With the government's efforts to promote and support the development of environmental protection and energy-saving industries, the "energy-saving business" of the security industry in the rapid development stage has received unprecedented opportunities for development. The security industry is constantly increasing its focus on energy conservation and consumption reduction. Many areas have also begun to pay more attention to energy-saving and environment-friendly security products and systems, such as safe cities, transportation, and building construction.
"The 12th Five-Year Development Plan for China's Security Industry" clearly stated that in the next five years, China's security industry will adhere to high technological content, good economic returns, low resource consumption, low environmental pollution and full utilization of human resources. The development of a new type of industrial intensification. Premier Wen Jiabao of the State Council stated in a speech at the Copenhagen Climate Change Conference: "China will fully implement the ten key energy conservation projects and 1,000 enterprise energy conservation plans and carry out energy conservation actions in key areas such as industry, transportation, and construction." It is enough to prove that "energy conservation and environmental protection" has been deeply rooted in people's minds and is imperative.
Security energy saving is imminent
With the enhancement of people's environmental awareness and the continuous emergence of advanced technologies, the green building industry has shown a rapid development trend and gradually formed a prosperous market. In smart buildings and green building projects, a reliable physical security system including energy-saving monitoring and access control equipment is an important part of a successful building management system. For the security products used in green buildings, “energy saving and environmental protection” is placed first, with the goal of significantly reducing energy غير مجاز مي باشدts while improving the user’s experience and minimizing operating غير مجاز مي باشدts.
It is understood that in smart buildings, construction professionals will put an average of 5% of the total construction غير مجاز مي باشدt into the security system. Compared to the construction غير مجاز مي باشدt, the average غير مجاز مي باشدt of the security system is lower, but it has a reliable set in the intelligent building. Security system is very necessary. Intelligent building system integration is mainly divided into two forms: one is to integrate the data of security systems, building automation systems, and fire protection systems, and manage them on a unified platform; the other is to automate building security, security, Fire-fighting, information equipment systems and information-based application systems are integrated to form an IBMS system. These five systems are controlled by a unified platform. The latter has many integrated systems and is generally applicable to banks, enterprises, and other special requirements. Things. In this sense, the security system is one of the indispensable subsystems in the system integration of building construction. In the past, physical security was added as a supplement after the main design of the building project was completed. However, with the increasing emphasis on security and the building becoming more and more complex, security design was able to intervene early in the entire construction life cycle. .
The security industry, as a material life requirement for the development of human life, has experienced rapid development in recent years, and its number of energy-consuming devices is very alarming. According to incomplete statistics, there are more than 1.2 million security systems of various risk levels in the country, and more than 200,000 security systems of various types are newly built and rebuilt each year. With a large number and large scale, it is undoubtedly a new demand for energy-saving construction of security systems. For example, with the rise of large-scale projects, the application of video surveillance systems has become increasingly popular, resulting in an increase in the amount of back-end storage and an increasing demand for energy consumption. According to Xu Tao, the deputy general manager of Beijing Guanlin Yingke Intelligent System Integration Co., Ltd., “The video surveillance in the security system is moving in the direction of high-definition, and the ensuing energy consumption is also correspondingly larger, such as high-definition images for transmission cables, The back-end storage has increased the pressure, which means that the energy consumption of the security system in the entire weak system of the building will be ranked in the top three, and the energy-saving of the security system will be mentioned as an important part of the overall energy efficiency of the building.
Although it is at the start, it is still surging
At present, although security and energy saving have not been taken seriously by real estate developers and actual users in building construction, the energy consumption of security products has become increasingly prominent. For example, it is well-known that computer rooms in building construction are used as high-energy-consuming sites in security systems. It has always been considered as a standard for energy conservation and environmental protection of equipment suppliers and system builders. There are a large number of data storage devices in the machine room. They need to work all the time without interruption and consume a lot of power. Taking data storage as an example, as the hard disk capacity increases, the power required by the hard disk also increases. If an energy-saving hard disk maintains stable performance, the power consumption can be reduced by approximately 4 W, saving a lot of electricity غير مجاز مي باشدts in a year. , And a system with 5,000 hard drives (small domestic centralized back-office storage) can save a considerable amount of money in a year. At the same time, too much heat will bring about a series of problems such as cooling of air conditioners and thickening of cables. If energy-saving products are used in security projects, unnecessary hidden غير مجاز مي باشدts can be reduced. As described by Beijing Guanlin Xu Tao, “Digitalization has promoted the development of security in the direction of energy conservation. It can be seen that any proposed energy saving is the result of large energy consumption. Security and energy saving in the future will become a bright spot for energy conservation in building construction. In the fifth plan, whoever first puts energy conservation into the security system well, whoever will have more market share."
From the perspective of product technology, as the building construction security market continues to expand, the advantages of energy-efficient products are becoming increasingly prominent. Most of the project traders and users have been bothered by the fact that the clarity and power consumption of the camera are directly proportional to the quality of the image. At the same time, how to ensure high-definition image quality without increasing power consumption, and achieving energy conservation and environmental protection, some are very strong. Companies with R&D capabilities have come up with very good ideas, such as innovations in chip and compression technology, to provide users with both good and energy-efficient products. With the global demand for energy conservation and the low power consumption demand of security customers, video chip suppliers are urged to make every effort to produce as many energy-efficient video solutions as possible, which not only creates the conditions for the security system to save energy in building construction. , but also for their own can occupy more market share in building construction efforts.
Judging from the perspective of the state policy, the State Council issued the “12th Five-Year Plan for Comprehensive Energy Conservation and Emission Reduction Work Program” clearly stated that the government will give full support to its fiscal policy: on the one hand, it will increase central budget investment and central government energy saving. Efforts will be made to reduce investment in special funds to accelerate the implementation of key projects and capacity building; on the other hand, local finance will deepen support mechanisms such as “subsidizing with awards”, “using incentives to promote governance”, and adopting financial subsidies to promote energy-efficient products, and strengthen such support mechanisms. The guiding role of financial funds. In addition, the government will also focus on green procurement and gradually increase the proportion of energy-saving and environmental-friendly products. For the security industry, security applications will continue to deepen in the fields of government, finance, transportation, and building construction, and energy-saving and environmentally friendly security products and projects will be affected. Promotion.
Party A is less concerned with security and energy conservation
At present, most users of building construction are favored. The building control system brings about energy saving in the operation of various subsystems such as air conditioning, heating, power distribution, lighting, elevators, and drainage. They believe that this type of building control is more energy efficient. Intuitive, obvious; and relatively speaking, the security system in the product of energy saving and environmental protection, user attention is weak. Security system brings safety performance to users. In building construction, security systems emphasize protection of personal safety. For example, users only care whether the access control system can safely open or close the door, whether the video surveillance system can completely record images, and whether the alarm system can Timely, accurate alarms, etc., are unaware that security systems have gradually become large energy consumers in building construction. According to Guo Zhigang, Program Manager of Siemens Building Technologies (Tianjin) Co., Ltd., “At present, many building construction projects don’t pay much attention to security and energy-saving users. They are more about the performance of security products and can bring much security to the building itself. Protection, but for energy conservation, they are more likely to choose building control systems for energy conservation because the air conditioning, lighting and other subsystems under the building control system are more intuitive in terms of energy efficiency."
"From the perspective of what we have done, at present, Party A is generally unaware that security has become a big energy consumer, and the concept has not yet changed. It is also considered that building building security systems are not as energy-efficient as building control systems, but Building building energy-saving development point of view, security system energy-saving will be a major trend, but at present the need for engineering companies, integrators to actively guide customers.” Beijing Guanlin Xu Tao added.
Security and building control depth integration, linkage energy saving
In the building construction, people not only need a sense of security but also a sense of comfort. From the perspective of practical applications, there can be no more than security systems and building control systems. The former include monitoring, access control, and alarms. They play the role of * and security to safeguard the safety of people and buildings in the building. The latter plays the role of housekeeper and babysitter to realize the automatic control and management of air-conditioning, hydropower, lighting, elevators and other equipment in the building. The two systems of security and building control go from the initial parallel relationship to the current intersection relationship, mainly reflected in linkage and integration, such as linkage control of access control systems, linkage of cards and elevators, and even in many building buildings, security and buildings. Controls operate on the same platform and share data with each other. When emergencies occur in buildings, they cooperate with each other to ensure building safety. According to industry statistics, through the integration of applications can achieve 10% to 20% of energy-saving building buildings, in addition to centralized control, optimization of operations, can effectively control the equipment maintenance cycle, saving maintenance غير مجاز مي باشدts. According to Yao Jianmin, executive vice president of intelligent construction division of Zhejiang Zheda Central Control Information Technology Co., Ltd., said: “The security system saves manpower غير مجاز مي باشدt in building building energy saving, and can also be linked with other systems, optimize the building management system, and achieve internal Energy savings."
"The integration of security systems and building control systems, through the combination of access control, alarm, video surveillance, energy management, vehicle access management, elevator management, and web-based guest management tools, enables users to manage and control through an integrated unified platform. Improve energy efficiency and reduce building control غير مجاز مي باشدts, added Liu, marketing manager of Tyco Fire & Security (Tianjin) Co., Ltd.
With the concept of building energy conservation, the status of security systems in building construction has become increasingly prominent. Of course, security and energy saving in building construction can be interpreted from three aspects. The first is to reduce the power consumption of the product and the system itself, so as to achieve the effect of energy saving; the second is the change of the power supply mode, in other words, the use of wind energy, Renewable energy such as solar energy or Power over Ethernet (PoE) technology. "In the past two years, with the rapid development of network video surveillance, Ethernet (PoE) power supply technology can not only transmit signals, but also provide DC power for network cameras. In this case, energy consumption can be reduced a lot." Beijing Guanlin Xu Tao, for example, said. The third can be understood as the effect of the security system on the energy saving and environmental protection of building construction. For example, the building area of an office building or conference center is usually large. If the equipment is not properly managed, the energy consumption rate will be very alarming. Siemens Building Technology Guo Zhigang example: "The public conference area can be linked through the access control system and the building control system under the security system, through the process of scheduled linkage with the access control system, according to the access control to control the lights, air conditioning, this allows Users intuitively feel the energy savings brought by the security system."
In recent years, the proportion of security systems in building construction has increased significantly. The security system has brought security to building construction and has also contributed to energy conservation and environmental protection. According to Liao Hangang, chief engineer of Shenzhen Dashi Smart Co., Ltd., “The current construction ratio of security systems in building construction has been increasing year by year. It provides convenience for the safety of building construction, and it also features 'consumer information' as a user. Bring low energy consumption, green, and sustainable lifestyles, and contribute to energy saving and environmental protection.” Through integrated monitoring of the entire building, as well as access control systems at entrances and exits, building control systems, etc. Data sharing can provide managers with energy-saving analysis and advice. For example, when an access control system is used in a hotel, when a guest enters a room by swiping a card into the card slot, it triggers the air conditioning in the room and the water and electricity are automatically turned on. When the guest checks in and out of the room, it is automatically closed, which not only brings customers Comfort and convenience are also very important energy-saving measures for hotel operators. Through the analysis of video surveillance images and access control credit card records, managers can obtain information on the distribution and accessibility of the flow of people in the building, which is conducive to the timely adjustment of equipment distribution within the entire building to the rational use of resources. “From a security point of view, installing access control equipment at the entrance to the building can understand the flow of people in the building on the one hand, and on the other hand, the building control system controls the light and temperature of the entire building based on the monitoring and access conditions.” Beijing Guanlin Xu Tao added.
High-definition and smart boost the energy efficiency of buildings
In recent years, China’s attention to energy conservation and environmental protection of building construction has gradually increased. The state’s policy on building development also places greater emphasis on greenness, environmental protection, intelligence, and sustainability. The most conspicuous energy consumption in building construction environmental protection lies in lighting, air-conditioning and other systems. According to statistics from related departments, lighting energy consumption accounts for 25% to 35 of the entire building's energy consumption, accounting for the country’s electricity. 13% of total consumption. The intelligent technology will play an important role in energy efficiency in building construction, as Shenzhen LSD Intelligent Liao Hangang said: “Intelligent technology not only greatly improves the comfort of human settlements, but also improves the energy conservation and environmental protection coefficient of buildings, with automatic fresh air. The system regulates indoor comfort and enables automatic temperature and humidity adjustment."
With the increasingly sophisticated security technology, video surveillance has developed in the direction of high-definition and intelligence. In building building energy-saving, the temperature and humidity of the air-conditioning can be adjusted through the function of video monitoring and intelligent analysis of technical points. When the number of people is large, the temperature is increased and the air is supplied. When the number of people is small, the supply of air is reduced. Or combine the video surveillance system with motion detection technology to form an intelligent space occupancy sensor (IOS) that accurately senses the number and type of indoor objects and the time the object spends in the detection area. The heating and air conditioning of the linkage building control system controls the indoor temperature and humidity. In addition, the linkage with the lighting system can also be performed through video monitoring and intelligent analysis technology. When people are observed, the lights are turned on, and when they are not, they are turned off to achieve effective energy saving. “Integration of the security system and the building control system can be used to control the lighting and temperature and humidity in the building through the linkage between the access control system, the monitoring system and the building control system. For example, it detects whether there is a person in the room through the access control swipe card, and the linkage switch Lighting, or the use of video surveillance intelligence analysis technology to determine the indoor flow density to control the temperature of the air conditioning."
In recent years, the proportion of security systems in building construction has increased significantly, mainly reflected in the installation and construction of video surveillance. At present, most building constructions require full-scale installation of video surveillance, and the requirements for image quality meet high-definition standards. The use of high-tech such as remote monitoring, intelligent analysis, and system integration has not only been updated in the front-end equipment, but also has changed in back-end data processing and storage. Although these have increased investment غير مجاز مي باشدts, they have been viewed from another energy conservation perspective. High-definition video surveillance is installed in the building in an all-round way, and intelligent analysis technology is used. Only one or several security personnel are required to monitor and monitor in the surveillance management room, which greatly reduces the labor غير مجاز مي باشدt. For example, when an incident occurs in a building, monitoring and control room personnel and joint operations with the outside security, can quickly and accurately stop the malignant changes in emergencies. Or the linkage between the alarm system and the monitoring system, when there is an alarm in a building, no security is required to rush to the place immediately. The monitoring staff can simply call a video somewhere to check whether the alarm actually occurs. If there is a real danger, then inform the security guard to rush to the office. And so on, through high-definition video surveillance to a certain extent liberated productivity, saving human resources غير مجاز مي باشدts. On the contrary, if it is artificially used to replace the role of security systems in building construction, how many security measures will be required for a single building? These labor غير مجاز مي باشدts may all exceed the غير مجاز مي باشدts of system construction.
In the past, most of the buildings were analog systems such as Burj Khalifa and Taipei 101. With the development of security technology towards networking, more and more intelligent architectures and green buildings adopt IP-based main architectures, which can minimize the amount of construction and installation of newly-built and reconstructed construction projects, and facilitate new construction in the future. The replacement of technology. For example, the traditional analog system is suitable for small-scale sites, but if it is to be extended to large-scale buildings, it will be restricted by the expansion. Using IP-based technologies, security systems, building control systems, and fire-fighting systems and other systems can Better and faster communication linkage. It is understood that in some new smart green building projects, there are already application cases that are based on simulation and IP-based security systems.
Under the increasingly grim situation of global energy issues, many security companies have keenly discovered that energy-saving products will certainly become the future development trend. At home, a considerable number of products in the security industry involve energy conservation. As far as the current market status is concerned, energy-efficient products are both market demand and market trend, and energy-saving products are not only the leaders of this trend, but also the pass for product suppliers, system integrators, and project developers to open their doors. All industries and industries around the world are conserving energy, and it is the responsibility of security and energy conservation. It can foresee the security market in the future. Whether the product will be energy-efficient or not will become the new standard for measuring the technical content of security products. For example, Zhejiang Jianzhong Yao Jianmin said: “Energy conservation and environmental protection are the major trends in the development of building construction. With the continuous development of the construction industry and the increasing demand for security, the 'energy saving and environmental protection' of security will be the mainstream of future building development. ."
