Pay attention to the suitability of choosing ppe

Enterprises are concerned about the traditional property management can not keep up with the demand of people nowadays for services. Therefore, the wisdom management of the community has become more important. To create a professional community service platform for the community, to solve the actual needs of the owners has become major real estate developers. And the problems that traditional communities urgently need to solve.

So, what is the establishment of a smart community system? What functions can the smart community service platform achieve?

I. Why are real estate developers now looking for a smart community transformation?

1. Changes in the scope of services Traditional property management includes the management of projects such as housing construction, public facilities, greening, sanitation, transportation, life order, and the environment. The community O2O model integrates various information systems and resources, builds a unified community information platform, and improves community services on the basis of traditional properties.

2. Transformation of business model From the traditional property to the community O2O, the change in business model is mainly reflected in four aspects: management focus, management methods, personnel structure and income structure.

Changes in management focus: The focus of traditional property management is on the management and maintenance of housing and ancillary facilities, related sites, and the maintenance of community environment and order. The community O2O model pays more attention to the needs of the owners and the property management becomes The process of co-management by the owners truly makes the service a reality.

Changes in management methods and personnel structure: Traditional property management adopts civil air defense management, which is a labor-intensive industry. There are many workers and low skill requirements. The community O2O uses information systems to achieve technical protection in security and surveillance. The managerial skills are also more demanding.

The change of profit model: The most direct change from traditional property to community O2O is its profit model. Community O2O income no longer depends solely on property management fees, and property management revenue will mainly come from various profitable ways such as customer value-added services.

OFweek smart home network news from Amazon in November 2014 launched the smart speaker Echo, more and more Internet giants began to join this hot market.

Followed by Alibaba's "Tmall Elf", Tencent vice president Liu Chi-Ping recently also publicly stated that Tencent's smart speaker products "ear" will be released around August, plus the previous "Jidong" and Baidu DuerOS wisdom chip Combining the actions of upstream partners in the field of smart speakers, the product roadmaps of major Internet companies in this area are gradually clear.

The rise in downstream industry enthusiasm has also given rise to the enthusiasm of upstream chip makers. Companies such as Qualcomm, MediaTek, Intel and Ziguang Zonui have all released smart speaker product lines this year. Some even believe that smart speakers will become the next e-consumer product after both mobile phone products.

“The consumer’s willingness to purchase smart speakers is increasing. With the infiltration of Amazon in other countries and the outbreak of the mainland market, there will be a very good development.” Deputy General Manager of U-Touch Technology and General Manager of Home Entertainment Products Group In an interview with reporters, if you look at the annual growth rate, it is expected that the volume of smart speakers in the industry this year will be three times that of last year.

A spokesperson for Ziguang Zengru revealed to reporters that the smart speaker products that carry the company’s chips have been shipped on a large scale, mainly smart and Bluetooth speakers within 300 yuan.

Market enters an outbreak

Following the mobile phone, smart speakers were initially considered to be another "killer" product that detonated the consumer market.

The consulting company, Strategy Analytics, predicts that the global shipment of smart speakers in 2016 will be 5.9 million units, which will increase 10 times in 2022 and the market value will reach US.5 billion. In the fourth quarter of last year, shipments of smart speakers increased nearly 600% year-on-year to 4.2 million units.

In fact, giants such as Amazon have begun to taste the sweetness in this area.

From the time of its official release in November 2014 to more than two years now, Amazon Echo Smart Speaker has become one of the hottest smart home products on the market. People can use Echo to control their home appliances, purchase goods, and inquire through voice. According to survey data from research firm eMarketer, in the United States, about 36 million users use voice-operated speakers once a month, and this number is still expanding.

As the market became clear, Apple, Google, Microsoft, Tencent, and Ali also started to enter the market, which also led to a significant increase in chip shipments of chip manufacturers in the field of smart speakers.

"Including intelligent voice assistant equipment, Internet of Things, power management and ASIC, we expect that revenue from growth products will exceed 30% in the next 1-2 years." After this year's MediaTek 2017 shareholder meeting, Chairman Cai Mingjie said in an interview with the media. At present, MediaTek is one of the main chip makers of the Amazon smart speaker Echo, occupying more than half of the shipment share.

Tourists Jie told reporters that MediaTek is expected to increase its share of Amazon at the end of this year, and is also cooperating with several domestic Internet giants in the field of smart speakers, as the most convenient human-machine interface, he believes that the market will be The second half of this year ushered in an outbreak. "In terms of annual growth rate, the growth rate of the smart speaker industry this year is at least three times more than last year."

Of course, MediaTek's old rivals Qualcomm, Spreadtrum, and Intel are also in the game.

At a developer conference last month, Qualcomm launched the "Smart Audio Platform." In addition to the chip itself, this new platform also provides developers with more development tools to help developers create smart audio faster, similar to Amazon's Echo and other products. Both new chips will provide support for two voice assistants, Google Assistant and Amazon's Alexa; they can also support voice recognition, voice over Internet Protocol (VoIP). Prior to this, at a technology development conference in Amazon, Intel announced high-profile development of a smart speaker based on the Amazon Voice Assistant called "Smart Home Hub."

Ziguang’s market is even faster, and its partners have already launched smart sounders at prices below 300 yuan. "At present, there are about dozens of our speaker customers, mainly smart and Bluetooth speakers within 300 yuan, the price of the chip is very competitive." Spreadtrum spokesman told reporters.

AI entrance?

"Intelligent speaker, hidden is the layout of various chip manufacturers in the field of smart artificial." Wang Yanhui, secretary of the Mobile Alliance, told reporters.

In fact, although it is called "smart speaker", Amazon's Echo function far beyond a speaker, it is more like a tool for home users to use voice to access the Internet, such as on-demand songs, online shopping, or to understand Weather forecasts can also be used to control smart home devices, such as opening curtains, setting the temperature of the refrigerator, warming the water heater in advance, etc.

In other words, the smart speaker is more like a prototype of a “home robot,” and it provides better service and better decisions through historical data and current data. Wang Yanhui told reporters that this kind of manipulation through voice is not only limited to homes, but also cars, shopping malls, etc., and chip makers are entering because they see a bigger market.

Take Intel as an example. Although Intel has been extending its artificial intelligence technology to acquire Nervana, a leading provider of deep learning and neural network chips and software, in recent years, Intel has not yet had a product comparable to the PC era in terms of consumer products. It can be "endorsement." Therefore, many people in the industry believe that the cooperation with Amazon is not so much that Intel wants to share the smart speaker market. It is better to say that it has taken a fancy to the smart home products and other larger artificial intelligence chip markets.

At the cooperation summit with Baidu, the chief scientist of Ziguang Zonui and Wei Dike, CEO of RDA Microelectronics, were even more blunt. Artificial intelligence is essentially the application of voice computing. The chip companies can provide various interfaces, communications, and low-level chips. In order to achieve the role of artificial intelligence portal. In the future, the power of domestically produced chips on smart voice will focus on three points: lower power consumption, smaller size, and more powerful functions. Rui Dike plans to work together with Baidu and ARM to release a chip every year.

In the opinion of the visitors, after the deep learning was proposed, the learning of the AI ​​became easier, and the implementation of the hardware architecture also achieved a major breakthrough. This is why Amazon began to have such products as Echo. At the same time, he believes that smart speakers will become the future "service entrance." "At present, smart speakers are not just voice conversations. What people value more is the service brought by this product in the future, or what kind of service will be integrated." The visitor Jiejie told reporters.

In any case, whether it is smart speakers or artificial intelligence, it is certain that, following the mobile phone, another round of new opportunities for chip manufacturers is coming. Wang Yanhui told reporters that voice is becoming a central user interface, which will stimulate the recovery of the upstream industry chain including the chip industry.

According to reliable data, most of the global tools are produced by enterprises in China, the United States, and Germany. After 30 years of rapid development, China has become the world’s leading tool manufacturing center and consumer market. In addition to fully satisfying the domestic market demand, China’s hand tools and power tools have also been exported to many countries around the world. China's tool manufacturing plays an important role in the global industrial chain.

At present, China’s tool hardware industry is in a critical period of improving its core competitiveness. The mainstream companies in the industry are increasing investment in technological equipment and transformation to take the path of healthy development with low carbon, environmental protection, and energy conservation. The domestic tools have determined the development goals for the next five years, and strive to achieve a transformation from qualitative change to qualitative change through the joint efforts of the entire industry. Shi Lanlan, executive vice president and chairman of the China Association of China Hardware Products Association, said in an interview.

Statistics from the customs show that during the period of the 11th Five-Year Plan period, the growth rate of China’s tool exports has exceeded 20 per year. In 2010, the total value of China’s exports of various tools exceeded 8 billion U.S. dollars; in January-June this year, the export value was 4.904 billion U.S. dollars. The year-on-year increase of 25.4. At present, more than 160 countries in the world have Chinese tool products.

If a manufacturing industry wants to cast a world brand, it must not only improve product quality and technical level, but also have persistent and innovative spirit. It is reported that in the next five years, domestic tools will strive to achieve new breakthroughs in product development, standard setting, and market development. There are five specific development goals: First, the whole industry will strive to achieve export volume of US billion by 2015 on the basis of steady growth, of which the export of self-owned brands will reach 10-15. The second is to guide the Dragon Skull Dry Enterprise through equity optimization. Such as forming a joint force to participate in international market competition. In this process, we must basically eliminate high energy consumption and high pollution companies. The third is to introduce advanced management systems, increase research and innovation, and strive to establish one or two provincial or national engineering technology centers to ensure that the funds used for R&D and innovation are not less than 5 percent of the sales revenue, and half of the patents declared or obtained Put into practical use. Fourth, large enterprises should be encouraged to do a good job of quality management, establish a high-level laboratory equipped with advanced professional testing instruments, and be used for daily quality supervision. Fifth, we must increase the popularity of Chinese brands in the international market, and strive to make more Chinese-made tool products into foreign high-end markets; at the same time, increase the share of domestic high-end products.

To achieve the above goals, we must first vigorously develop the cultivation of China's tool brands, in particular to increase and expand the awareness of China's own brand of tools in the domestic and foreign markets, so that enterprises can constantly improve their competitiveness in the process of nurturing and creating brands. Large-scale investment in technology and equipment, in the next 5 to 10 years and strive to form a group of enterprises with an annual output value of 1 billion yuan, and nurtured 3 to 5 world-renowned tool brands and a large number of well-known brands of domestic tools.

Zhang Dongli, chairman of the China Hardware Products Association, added that during the 12th Five-Year Plan period, the domestic tool industry should step up the pace of transformation and upgrading. Manufacturers should pay more attention to quality safety and technological innovation. Only in this way can the Chinese tool industry realize the advancement from a manufacturing power to a manufacturing power. At the same time, the entire industry can not carry out vicious competition, peers should join hands together, and through cooperation with international counterparts to promote their own and global hardware industry development.

A number of well-known companies have emerged in the tool industry in China. The heads of these companies have also expressed their own views on the development direction of the industry in the next five years and the company's development priorities. On behalf of companies, the rapid economic growth and substantial increase in income have led to an increasing demand for high-end and branded tools in the market. This is also the key to making domestic tools more competitive in the future. Like other manufacturing industries in China, at present, domestic tools face the challenges of rising labor غير مجاز مي باشدts, shortages of ancillary products, insufficient power resources, and increasingly stringent environmental protection requirements. Faced with these challenges, we must achieve sound development in the face of these difficulties. The production line will intensify the transformation to ensure high efficiency and high quality.

In 2014, the scale of China's smart home market will reach 28.61 billion yuan. It is expected that it will exceed 300 billion yuan by 2020, which shows that the potential for market development is large.

It can be expected that with the continuous improvement of Internet technology, if the “new generation” of smart home products can take the lead in this market, it will have an inestimable effect on the enterprise and the industry. The status of locks in smart homes can not be ignored. We can not do everything in smart homes. There is a “money map” as long as we grasp them.

As we all know, the size of domestic building openings is not uniform, making the door industry still dominated by customization. The non-standard customized production of the door industry (including the entrance door) gave birth to the customization of the hardware lock industry. At present, the trend of door lock bundled sales is becoming more and more obvious. Consumers are more inclined to purchase door products that are already equipped with locks. .

In order to comply with the needs of consumers, there are three situations in which a lock company cooperates with an entry door company or a decoration company:

The first is that lock enterprises become a supporting “production workshop” for door and window companies, and the brand is the brand of the door factory (which can also be understood as the door factory for OEM);

Second, the brand of the lock enterprise and the product brand of the door factory are independent, match each other, and cooperate strategically, and appear in the form of a door vendor's special hardware lock supplier.

In the third kind, after a certain decoration design company receives an order, it arranges the door company and the lock company to produce according to the order, but the brand owner of the door and the lock is a decoration design company.

Of course, if the lock company's products become the industry's forward-looking, innovative and differentiated new generation of smart lock products leader, become a smart home entrance, it will be more attractive to enter the door enterprises and lock companies to achieve cooperation, will also prompt them Marketing or technological innovations for products of the category.

The smart door lock is passive and active. Before the joint doors and windows and real estate development, the door companies occupy a dominant position in the cooperative relationship between door enterprises and traditional machinery lock enterprises. In most cases, mechanical lock enterprises seek cooperation from door companies, and few door companies actively cooperate with lock factories. Most bosses of mechanical locks also believe that locks are accessory products for the door. Only if the door factory is satisfied, then the lock product can be sold.

But now, we need to think backward: The intelligent and technological content of the door and window industry is the smart lock, a differentiated and forward-looking smart lock product. Why can it not affect the product adjustment and innovation of the door company in turn? ? Impact on their sales strategy, or even procurement cooperation thinking? A "mobile-side smart lock" that profoundly cuts consumer spending trends and consumer trends, can bring bright spots to household entrance products, increase "selling points", improve grades, attract consumers, promote sales, and deserve to enter the door Actively focus on and change ideas.

In addition to the traditional docking industry, the real estate market is also a direction in which smart door locks can be developed.

The real estate market is not a constant temperature environment. For developers, improving intrinsic value and competitiveness is the only way out. The smart home as a new highlight of refined decoration has been favored by developers.

According to the China Real Estate Index System Monitoring Data Report, among the 40 large and medium-sized cities in China, over 17% of the existing real estate projects for sale and for sale are fine-tuned projects, of which the fine-tuned projects in Guangzhou and Beijing have reached 47% respectively. 30%. From the perspective of the project proportion of the top 100 real estate companies, the refined decoration project has become the main product.

Among them, Vanke Real Estate's major projects in 2009, the proportion of fine decoration more than 80%, while in 2010 the new start of apartment projects to achieve 100% fine decoration, fine decoration housing is gradually becoming the mainstream trend of the real estate market. However, with people's constant pursuit of high quality of life, simple and exquisite home stacking can not meet the needs of consumers, and intelligence has become the pursuit of simple aesthetics.

The use of science and technology will develop digitalization, networking, and integration of home furnishing. This process integrates the application of triple-play technology, the Internet of Things, and 3G technologies, reflecting the humanization and daily life of the living environment. Features such as simplification bring great convenience to residential users and firmly grasp their psychology of pursuing high quality and high intelligence.

As a result, it has become an important opportunity for the development of the real estate industry. Walnut wisdom lock is the outstanding representative of smart home decoration. Its outstanding aesthetic design and outstanding intelligence degree not only make it a new design element and new bright spot for decoration companies and designers, but also for real estate. Soft value development has injected new vitality.

It is expected that in the next 3-5 years, with the strengthening of the development trend of the Internet and smart homes, the integration of door entry enterprises and a new generation of smart lock enterprises will develop in depth. High-sensitivity, industry-leading and innovative entrants will also focus on the consumer demand after the 80s and 90s under the influence of Internet thinking, and will use the mobile phone's product opportunities to differentiate their industries. Chain partners, forward-looking choice of smart lock accessory products, do a full range of products, do marketing, service, brand.

Valve is a kind of widely used mechanical parts. Its role in modern production and life is more and more significant. No matter whether it is high-end technology or daily ordinary life, it is inseparable from it. It is because of the extensive application of valves that the types of valves are very numerous and the structure is not the same, which also brings certain problems to the maintenance of the valve. Although the types of valves are numerous, the basic role is the same, that is, connecting or cutting off the flow of media. Therefore, the valve sealing problem is very prominent.

To ensure that the valve can cut off the flow of media well and that no leakage occurs, it is necessary to ensure that the seal of the valve is intact. There are many causes of valve leakage, including unreasonable structural design, defective seal contact surfaces, loosening of fastening parts, and incompatibility between the valve body and the valve cover. All of these problems may result in the valve not sealing. Well, there is a leakage problem. Therefore, the valve sealing technology is an important technology related to the valve performance and quality, and requires systematic and in-depth research.

The classification and structure of the valve is very diverse. It is not easy to divide the valve. It can be divided according to the principle, or it can be divided according to the function. It can also be divided according to the structure, and it can even be combined to divide. No matter what kind of partitioning method, Can not change the use of the valve. Currently, the commonly used classification method in the world is to classify valves into these types, namely, gate valves, ball valves, butterfly valves, globe valves, safety valves, pressure reducing valves, throttle valves, plug valves, and control valves. In these valves, gate valves, ball valves, butterfly valves, and globe valves are classified as shut-off valves. They are mainly used to connect or shut off the flow of medium, and pressure reducing valves, throttle valves, and control valves are the types of control valves. It regulates the flow, temperature, and pressure of the medium flow, while the safety valve is mainly used for overpressure safety protection.

In addition to these classifications, they can be classified according to working pressure. At this time, they can be divided into vacuum valves, low pressure valves, medium pressure valves, high pressure valves, and ultra-high pressure valves; if classified according to the working temperature of the medium, they can be divided. For the high temperature valve, medium temperature valve, room temperature valve, cryogenic valve and cryogenic valve; In addition, if classified according to the material of the valve body, it can be divided into metal valve, non-metallic material valve, metal valve body lining valve.

Although the types of valves are numerous, the basic structure is almost the same, and they can generally be composed of a valve body, a valve core and a valve seat. Here take the most commonly used control valve as an example to analyze the valve's structural composition. In the basic valve body structure of the regulating valve, there may be three types of straight-through, angular and Z-shaped structures; in the basic valve core structure, there are three types of parabolic structure, cage structure and V-shaped groove. In the basic seat structure, there are four types of surfacing valve seats, screw-in seats, welded seats and seated seats. The combination of these different basic structures constitutes a wide variety of valve structures. The basic structure of the valve is shown in Table 1.

Research status of valve sealing technology Although the types of valves are numerous, sealing problems are indispensable and very important. Since the valve was produced, its sealing technology has also undergone great development. So far, valve sealing technology is mainly reflected in two major aspects, namely static seal and dynamic seal. The so-called static seal, usually refers to the seal between the two static surfaces, static seal sealing method is the use of gaskets. The so-called dynamic seal, mainly refers to the valve stem seal, that does not allow the valve media to leak with the stem movement, dynamic seal sealing method is mainly the use of stuffing box. The following is a detailed analysis of these two valve sealing technologies.

Static and static sealing refers to the formation of a seal between two stationary sections. The method of sealing is mainly the use of gaskets. There are many kinds of washers. The frequently used washers include flat washers, O-rings, packing washers, shaped washers, wave washers, and winding washers. These types can be further divided according to the materials used.

1 Flat Washer Flat washer is a flat washer that is attached between two stationary sections. It can be divided into plastic flat washers, flat rubber washers, flat metal washers and flat flat washers, flat washers for each material depending on the materials used. Have their scope of application.

2 O-ring O-ring is a gasket with O-shaped cross-section. Because its cross-sectional shape is O-shaped, it has a certain self-tightening effect, so the sealing effect is better than flat washers.

3-Pack of Gaskets A gasket is a gasket that encloses a material on another material. Such gaskets generally have good elasticity and can enhance the sealing effect.

4 Profile washers Profile washers are those that have irregular shapes, including oval washers, diamond washers, gear washers, dovetail washers, etc. These washers are generally self-tightening and are used mostly in high and medium pressure valves.

5 Wave washers Wave washers are washers with only wavy shapes. These washers are usually made of a combination of metallic and non-metallic materials. They generally have a small pressing force and a good sealing effect.

6 Wrapped Wraps Wrapped washers are gaskets that are formed by tying very thin metal tapes and non-metallic tapes together. These gaskets have good elasticity and tightness.

The materials for the manufacture of gaskets mainly include three major categories, namely metal materials, non-metal materials, and composite materials. In general, metal materials have high strength and high temperature resistance. Commonly used metal materials include copper, aluminum, and steel. There are many types of non-metallic materials, including plastic products, rubber products, asbestos products, hemp products, etc. These non-metallic materials are widely used and are selected according to specific needs. There are many types of composite materials, including laminates, composite panels, etc., which are also selected according to specific needs. Generally, they are used in wave washers and wound gaskets.

Dynamic seal seal refers to the seal that does not allow the media flow in the valve to leak with the movement of the valve rod. This is a seal problem during the relative motion. The seal method is mainly the stuffing box. There are two basic types of stuffing box, namely gland type and compression nut type. The gland type is the most used form at present. Generally, from the form of the gland, it can be divided into a combination type and an integral type. Although each type has a difference, it basically contains a bolt for pressing. Compression nut type is generally used for smaller valves. Because of the small size of this form, the pressing force is limited.

In the stuffing box, because the packing is directly in contact with the valve stem, all require that the packing has good sealability, low friction coefficient, can adapt to the pressure and temperature of the medium, and is resistant to corrosion. Currently used fillers include rubber O-rings, PTFE braided packing, asbestos packing, and plastic molding packing. Each packing has its own conditions and range of adaptability, and it is selected according to specific needs.

The prospect of valve sealing technology With the continuous development of science and technology, the requirements for valves are also getting higher and higher, so the valve sealing technology is also constantly developing, and new sealing materials and technologies are also emerging. Mainly reflected in the following aspects:

1 raw material seal What is raw material? It is the material of the polymer organic compound before it is sintered into the product. The raw material has a soft texture and can produce a monomolecular film effect. The raw meal can be shaped freely when used, and as long as there is pressure, a uniform annular membrane will be formed. This annular membrane plays a sealing role. Raw materials are very convenient to use, can be made into a certain shape, easy to replace, and good sealing effect.

2 Liquid Sealing Liquid sealing is a sealing technique that uses a liquid sealant to seal a valve. It is generally used for static sealing. In the liquid seal, the monomolecular film effect of the liquid sealant is mainly utilized so that it acts like a gasket under proper pressure.

3 Bellows seals Bellows seals are sealing techniques that use bellows to seal valves. They are generally used for dynamic seals. In the bellows seal, the two ends of the bellows are usually fixed together with other parts, so when the valve stem moves, the bellows will expand and contract. As long as the bellows itself is intact, the medium will not leak, so that it can be Seal the valve. This kind of valve sealing technology is mainly applied to the chemical industry and atomic energy industry, and it is aimed at the situation where the packing cannot be sealed.

With the further development of the economy and society, the application requirements of the valve will be higher and higher, and the valve sealing technology will also advance by leaps and bounds. More new materials and new technologies will also be applied, and the research on this aspect will be more and more in-depth. .
