HXPnR-H type protective safety slide wire, its conductive body is a section of "H" copper profile, it is also called "H" type energy-saving slide wire device, energy saving is relative to the angle wire as the main line of the trolley wire, electrical energy in Loss during transmission is greatly reduced. The resistivity of copper is much lower than that of steel, and the specific gravity is small. Rolling the copper into the "H" type is based on ensuring a certain conductive cross-sectional area to improve the overall rigidity and strength. However, copper has a low surface hardness and is not wear resistant. In order to make the aluminum substrate meet the practicality as a conductive slide wire, the "H" shaped middle beam is made into an upper arch type, and a stainless steel section with high wear resistance is embedded here according to a prescribed process procedure. This "H" shaped stainless steel profile serves as the frictional transmission surface of the conductive block in the conductor, and its inserting process ensures the tight integration of stainless steel and aluminum profiles, and the current introduced into the copper profile is kept in contact with the stainless steel body. The guide block in the conductive device transmits the current in the friction contact, which ensures the continuous current of the hoisting machinery during operation.

Nowadays, electromagnetic flowmeters have been widely used, but in order to make them better, we can't ignore its detection. The following Chengfeng Instrument will talk about five special tests on electromagnetic flowmeters for you.

1. Electrode contact resistance. Measuring the liquid contact resistance value of the electrode spoon can indirectly evaluate the general condition of the surface of the electrode and the liner layer without removing the flow sensor from the pipe, which is helpful for analyzing the cause of the failure.

2. Polarization voltage of the electrode. Measuring the polarization voltage between the electrode and the liquid will help determine if the zero-point instability or output sloshing fault is caused by the electrode being contaminated or covered. With a digital multimeter 2V DC gear, measure the polarization voltage between the two electrodes and the ground (the electromagnetic flowmeter can be measured without interruption or blackout). If the two measurements are nearly equal, the electrodes are not contaminated or covered. The magnitude of the polarization voltage is determined by the "electrode potential" of the electrode material and the nature of the liquid. The measured value may be between a few mV and a few hundred mV. Because the two electrodes are actually contaminated during operation, it is not possible to be completely symmetrical, so the voltage across the two electrodes forms an asymmetric common-mode voltage. The asymmetric common-mode voltage becomes a differential mode signal, causing a zero offset.

3. Pipeline stray current flow discriminant. Sometimes to find the spurious source of interference in the pipeline upstream or downstream of the flow sensor to narrow the search, try to reduce or eliminate the effects of stray current interference.

4. Determination of signal cable interference. The signal cable is affected by the external electrostatic induction and electromagnetic induction interference will make the electromagnetic flowmeter zero point change. To determine whether the zero point change is due to signal cable interference potential influences, it is necessary to determine the general scope of the interference and the degree of influence on the electromagnetic flowmeter.

5. Determine if there is a ground potential. Electromagnetic flow juice in the normal use of the process, such as the sensor near the motor (force) status changes (such as leakage), the ground potential will change and cause a zero point change. Check if there is any influence in this way. Short circuit the converter's working ground C terminal and protective grounding G terminal, and judge whether there is a grounding potential by changing the zero point (or indication value).

After the "Home Appliances Going to the Countryside" and "Cars to the Countryside" received rave reviews, the 'building materials going to the countryside' that the Central No. 1 document introduced this year followed. Due to export difficulties, many architectural hardware companies began to consider 'export to domestic sales', the introduction of the policy can be described as sending in the snow. Industry insiders believe that building materials to the countryside will not only provide huge opportunities for related industries such as construction hardware, but also will be conducive to industrial restructuring, speed up the development of competitive enterprises, and backward production capacity.

It is reported that the products of building materials to the countryside must first be products that meet the relevant national regulations and have a certain scale and are produced by regular manufacturers. Although the price is low, the production process and the level of backward products will not be included in the scope of building materials to the countryside. Therefore, building materials to the countryside is precisely to encourage the development of advanced technology, environmental protection and energy saving building materials companies, and to reject low-tech, high pollution, high energy consumption products.

China is widely recognized as a major manufacturer of hardware products. Its background is that China’s labor resources are abundant and cheap, but its products have low technological content and need to be transformed from producers to creators. First-class products are sold to Europe and the United States, and inferior goods are sold domestically. Chinese hardware companies need to produce their own products with core technologies.

Nowadays, low-carbon heat has emerged in the architectural hardware industry. In the future, the building will pursue the pursuit of low-carbon, energy-saving, green, and environmental protection. In the future, the construction industry will inevitably adopt a large number of new materials featuring low-carbon technologies. The market demand for new energy-saving and environmentally friendly construction hardware products will maintain long-term growth. Construction hardware companies will inevitably improve technological innovation and develop more energy-saving products. At the same time, the architectural hardware industry will increase resource conservation and environmental protection efforts, and strive to achieve industrial structures that are mainly energy-intensive and capital-based, technology-based, and knowledge-intensive. Change and reduce the proportion of high energy consumption, high pollution and high convergence industries in the national economy.

At present, some domestic construction hardware companies have gradually evolved from processing-type enterprises into independent-innovation high-value-added enterprises, positioning themselves as 'international, professional, technology-oriented, and market-oriented', and mainly exporting. Architectural hardware suppliers pay more attention to brand building and technological innovation. They are already gearing up and hope to step out of a new world in the context of expanding domestic demand.

In the 1960s, China's hardware accessories began to use strip steel blanking, continuous processing such as punching and many Other processes. The surface is electrophoretic dip lacquer, electrostatic spraying and other processes, the quality has been improved.

In the 1980s, along with China’s reform and opening up, foreign construction hardware gradually entered the Chinese market. In addition to integrated Chinese and Western hardware products, aluminum alloys were also popular for die casting and precision casting hardware. The three-dimensional appearance was strong and the lines were clear and smooth. The surface is powder coated or electroplated into copper, chrome, gold, silver and other colors, the shape has been greatly improved.

Stepping people In the 1990s, with the development of China's construction industry and housing industry, people's demands for performances became higher and higher, and the hardware market saw a strong sales momentum. The hardware products of developed countries have entered the Chinese hardware market one after another. Infrared remote-control automatic doors, door closers, floor springs, rolling shutter doors, plumbing hardware, door and window hardware, automatic door locks, etc. of the United States, Japan, Korea, and EU countries, all products are available. , Strong sense of plastic arts, advanced surface treatment technology, high product accuracy, a variety of high and new technology have been used in architectural hardware products, products to mechanical and electrical integration, intelligent direction.

“From the perspective of domestic product development, products from Guangdong, Jiangsu, and Zhejiang are more popular among consumers, and as the birthplace of China’s architectural hardware products, Shanghai’s product market share is relatively low and there are not many new products. , lack of awareness of innovation, lack of cultural heritage, worthy of causing attention of relevant departments.” International mold and hardware and plastics industry supplier association Luo Baihui said that the 21st century is the golden period of the development of architectural decoration hardware industry, more consumers in order to highlight the personality , The acquisition of hardware accessories of different grades, intelligent electronic control door locks, electrical plugs, non-contact electromagnetic door locks and other market sales gradually increased, indicating that China's decorative hardware market will have a bright future.

With the rapid rise of China’s economic strength, China has become the most dynamic economic region in the world. China's economic facilities are relatively complete, its industrial development is relatively mature, and its labor غير مجاز مي باشدts are relatively low. It has the comparative advantage of becoming a global hardware manufacturing center, and its outward-oriented development characteristics are obvious.

The requirements of the international market for China’s hardware products began to gradually develop and change. They have higher requirements for the quality, packaging, and delivery terms of Chinese products, and even gradually extended to the production process and product research and development, product and environmental protection, energy resources, The human environment is combined. With the deepening of competition, the profit space in all stages of the hardware industry chain is being compressed, and the space for price reduction is decreasing. More and more companies are realizing that it is impossible to establish core competitiveness based on price competition alone, and not the direction of long-term development, in an effort to explore new development paths. Many hardware companies have increased their investment in technology, developed new products with high-tech content, used product differentiation as a long-term plan for business development, sought new market demand, and established new economic growth points to realize the Continuous development.

The hardware industry's marketing targets are generally group and institution purchasing behaviors with obvious industry characteristics. Therefore, the marketing target is not the individual consumers facing the fast-moving consumer goods industry, but the production users who are characterized by industry users and invest in reproduction; Product structure: Technology is relatively specialized. The hardware industry is generally a system-integrated specialized product. Regardless of whether it is a construction machine or a central air-conditioner, the level of product specialization is generally very high, and the technical entry threshold and capital threshold for product entry are high. Third, the marketing model: direct marketing Mainly supplemented by channels. Because the technical content of the product structure is relatively high, and most domestic dealers rely on market opportunities, the relative overall quality is low, and it is impossible to rely entirely on channels. The distributors in most channels act as large sales personnel and end users. Engage in business-oriented, involving professional programs and technical exchanges, basically based on manufacturers; and manufacturers want to produce more stable, we must pay attention to direct sales.

Therefore, the marketing model: Take the end user as the leader, take the order of the project as the goal, and guide the manufacturer as the development direction.

"We finally found a way to see this complex idea in the signal of MRI," said Marcel Just of Carnegie Mellon University. "The correspondence between thinking and brain activity patterns tells us that How are our ideas built?"

The artificial intelligence system shows that the brain consciousness module is constructed by various subsystems instead of the brain.

Scientists have developed a new "brain reading" AI system that can decode and express complex human thoughts by measuring brain activity. The artificial intelligence system shows that the building blocks of the brain's complex thinking structure are composed of various subsystems of the brain rather than language.

"We finally found a way to allow us to see this complex idea in the MRI signal."

The researchers found that the brain's encoding of 240 complex events, such as the yelling and yelling sentences in the experimental scenario, used 42 practically meaningful components, or seemingly reasonable semantics in the brain's nervous system. These sentences are the correspondence between the way of thinking of the brain and the pattern of brain activity. These characteristics include people, scenes, size, social interactions, and body movements. Researchers say that every kind of information is processed in different brain systems. This is the way the brain processes objective information. By measuring the activity of each brain system, this program can determine what type of ideas the brain system is considering.

The researchers said: “One of the great advancements of the human brain is the ability to incorporate individual concepts into complex ideas, not only thinking about bananas, but also thinking of eating bananas with friends at night.”

"Our approach overcomes the drawbacks of functional magnetic resonance imaging, which tightly combines the signals generated in brain activity from beginning to end, as if two consecutive words were read in one sentence," said Just.

This advancement has made it possible to decode ideas that contain several concepts. This shows how most people's ideas are composed, "only by constantly adding information.

The researchers used a computational model to evaluate how seven individuals had different neurological responses to the 239 sentences used as materials. Then, the program can decipher the 240th feature. They tested each of the 240 sentences in turn, which is called "cross-validation." The researchers said that the model can predict the characteristics of the first subset of sentences picked out, with an accuracy rate of 87%, although the system has never been predicted before. It can also have other uses: to predict the activation status of a previously invisible sentence, only to show its semantic features.

1 The output signal of the analog type sensor is generally tens of millivolts at the maximum. During the transmission of these weak signals from the cable, it is easily disturbed, which results in unstable system operation or reduced measurement accuracy. The output signals of digital sensors are all around 3-4V, and their anti-jamming capability is much larger than that of analog signals. The problem of weak transmission signals and interference is solved. 2 RS485 bus technology is adopted to realize long-distance transmission of signals with a transmission distance of not less than 1000 meters;

3. The bus structure facilitates the application of multiple load cells. Up to 32 load cells can be connected in the same system. Digital electronic truck scale to solve the problem of offset temperature effects and solve the time effect of creep problems - Intelligent Technology 1 to prevent the use of simple circuits to change the size of the weighing signal cheating;

2 Digital truck scales can automatically compensate and adjust for the effects of offset loads and temperature changes. Consistency and interchangeability are good. After multiple sensors are connected in parallel, the linearity, correction and performance compensation can be realized by software methods. System error can be reduced and the on-site installation, adjustment, calibration and adjustment of the scale body can be simplified.

3 fault automatic diagnosis, error mesغير مجاز مي باشدe code prompt function.

4 When the load is added to a load cell for a long time, its output often has a large change. The digital load cell automatically compensates for the creep through the software in the internal microprocessor. The digital electronic truck scale does not require weighing display. The instrument reduces the failure rate of the truck scale--the digital calibration technology 1 makes the calibration of the weighing device (four corners) biased automatically;

2 The scale factor and zero value of the instrument can be modified as required to make the coefficients of each sensor consistent with the zero parameters.

3 The digital truck scale can be directly connected to the computer to display the weighing process, reducing the weighing faults. Today's computer hardware is extremely reliable, so the weighing system thus formed is more secure and reliable.
