Video storage energy-saving effect is obvious green security becomes an inevitable trend

Obviously, the energy saving effect of video storage has obvious cumulative effects. As far as the security industry is concerned, due to the small scale of the previous market, the demand for energy conservation and energy saving effects are not obvious, but with the continuous expansion of the security market, the advantages of energy-saving products are becoming increasingly prominent.

With the rise of large-scale projects, the application of electronic monitoring systems has become increasingly popular, resulting in more and more back-end storage, and the demand for energy consumption is getting higher and higher. At this time, the difference between the energy-saving and cost-effective use of energy-saving products and general products is very obvious.

It is understood that Western Digital's green monitoring and control hard disk (GreenPowerAV) has obvious advantages in vibration damping. WD's GreenPower energy-saving technology enables the hard drive to reduce heat, noise and vibration during working hours, making the operation reliable without affecting performance.

As the hard disk capacity increases, the required power for the hard disk also increases. At present, the power consumption of the current 1TB hard disk is usually higher than 13.5 watts. WD has designed a 3.5-inch hard drive with energy saving as the main attribute. Western Digital's introduction of green hard drives compared to standard desktop hard drives on average saves 4 to 5 W of power while maintaining stable performance.

If a power-saving hard disk can reduce power consumption by 4W, it can save about 10 yuan in electricity a year, and a system with 5,000 hard disks (small centralized back-office storage scale in China) can save a very considerable amount of money in a year. At the same time, too much heat will bring problems such as cooling of air conditioners and thickening of cables. Using energy-saving products can also reduce these hidden costs.

Hard disk is an important aspect of the stable and reliable DVR. Although hard disk technology for DVR applications is already available on the market, hard disk hibernation technology is still a very important technology in DVRs. It is relatively easy to do in the embedded DVR, because the embedded DVR is the embedded system to control the hard disk to run, as long as the operating system can provide such an interface to complete the hard disk dormancy. However, on the PC, the entire hard disk system is managed by Windows. The system does not provide peripheral management of hard disks. Windows itself has a hard disk hibernation system. However, this system cannot meet the application requirements of DVRs.

In the Windows hard disk management system, Hanbang Gaoke made a lot of research and development work, successfully broke through the Windows management restrictions, can fully realize the artificial control of the hard disk dormancy, the significance of this technology is to greatly improve the life of PC-type hard disk recorders, Improve system reliability and reduce operating and maintenance costs. And can support embedded DVR and PC DVR hard drive sleep. The power consumption of a hard disk is about 15W. In addition to the improvement of reliability, the application of hard disk hibernation technology is also very energy-saving.

It is understood that 2 to 4 hard disks are usually installed in the DVR, and 8 hard disks are usually installed for long-term storage environments. After the hard disk hibernation technology is used, only one hard disk is powered on. All other hard disks are hibernated. When the hard disk needs to be replaced, the specified hard disk is woken up. The hard disk that does not need to work can be put to sleep to achieve power saving.

Chip technology extends to some enterprises with strong development capabilities in the direction of reducing consumption. Through active innovations in chip and compression technologies, it provides users with products that are both useful and energy-efficient, and promotes energy conservation as a consumer trend and industry trend. It is understood that the main products in Panasonic's security products all use low-power DSP chips. Since 1997, the energy consumption of cameras has been reduced by 9.4%.

The single-chip solution is characterized by high integration, low cost, and high reliability, and is suitable for applications in the DVR industry. Zhang Haifeng said that the single-chip 8-channel technology has been successfully used in Hanbang's full range of products, and the single-core and multi-energy technology has been applied to the products within the four-way system. One chip completes the compression, playback, storage, management, network, etc. A series of work.

Summary: Energy conservation has become a global consensus and security is the responsibility of energy conservation. Energy conservation will become a new standard to measure the technical content of security products, and the facts prove that this market trend is very obvious. Some experts predict that in the near future, energy-saving performance requirements of products will appear in specific security product standards, and the future product market will, to a large extent, be an energy-saving market.

“Wind and light combination” becomes the best new energy In addition to the energy-saving design of products, the ingenious use of renewable energy can also reduce the power consumption. The change of power supply mode has more important significance for energy conservation and emission reduction.

By utilizing the power generated by renewable energy such as wind energy and solar energy, energy loss is reduced and system costs are reduced. Its general manager Xu Hui said: "Smart use of renewable energy can not only save electricity, but also more and more for construction companies to save construction and equipment costs."

It is understood that even Huo Express Zhengzhou to Luoyang section of the use of solar photovoltaic power generation technology, the successful implementation of the solar power supply of the entire video monitoring system demonstration project, in order to solve the highway monitoring grid power supply construction cost, line loss, low power utilization and other issues Explored a new way. According to the actual needs of Zhengluo Road's overall monitoring, from the perspective of economy, energy conservation, environmental protection, and shortening the construction period, the monitoring system uses solar power to provide power for the entire section of the road from Zhengzhou-Luoyang Highway to Luoyang, which is approximately 220 kilometers in length. 100 sets of video surveillance cameras supply power. According to the report, after nearly five years of actual operation, the demonstration project's technical program proved to be mature and reliable. Compared with power supply from the grid, it can save 58.3% of investment in power supply and distribution projects, and save electricity costs by 220,000 yuan and petrol by 960,000 yuan in five years. Yuan, reducing 402 tons of carbon dioxide emissions, significant energy savings.

The solar-powered highway video surveillance system consists of solar arrays, battery packs, solar charge and discharge controllers, inverters, transformers, cameras, and optical transceivers. The solar photovoltaic power generation system generates photovoltaic current through solar module radiation in sunlight, and provides electric energy for the electric load. The current generated by the solar cell passes through the charge-discharge controller. On the one hand, the load is directly supplied with power. On the other hand, excess electric energy is stored in the battery to supply power to the load when light is insufficient. AC load can be converted into applicable AC power through inverters and transformers. In order to cope with the poor battery condition caused by bad weather conditions, the system can be configured with mains or self-generating emergency charging interface. In order to improve the reliability of the power supply system, the operational status of the photovoltaic system is uploaded to the monitoring center in real time through the optical transceiver, so that manual maintenance measures can be taken in time.

The main obstacle to the application of solar photovoltaic power generation technology in the highway transportation industry is the applicability of the power supply load. How to combine the power load characteristics of the entire highway monitoring system, optimize the design of the power supply system, reduce the power consumption of the power load, and improve the solar power system Efficiency is the key technical link of the project.

In order to ensure the continuous stability of the power supply, the application of solar energy and wind power combined video monitoring project also has certain applications. This is the "wind and solar power supply complementary road monitoring system", this type of project is called the "landscape combination."

It is understood that by the end of 2009, Xuzhou, Jiangsu Province, the first solar energy, wind energy monitoring system was officially opened. The system is located on the north side of the Qinhong Bridge in Xuzhou City. The Qinhong Bridge spans the Beijing-Hangzhou Grand Canal and systematically transforms the original road section. The location is far away from the urban area, and there is a certain degree of difficulty in the installation of the traditional power monitoring system. The application of the “wind-light combination” road condition monitoring system has obvious application effects. It is understood that this system is mainly composed of solar energy, wind power supply system and monitoring system. It can guarantee the power supply under any weather conditions, and can save more than 30,000 yuan in electricity bill each year.

In the first half of 2009, the “Scenery Probe” of the Suzhou section of Shanghai-Nanjing Expressway has also been put into use. The power generated by the windmill on this system has reached 400 watts, and the power generated by the two solar panels is 170 watts each. With wind power of 2.5 m/s, the windmill can rotate to generate electricity.

In fact, the current project of using wind energy and solar energy to provide power for security monitoring and control equipment has been widely used in Guangdong, Fujian, Jiangsu, and Gansu provinces. The system uses wind energy and solar energy to generate power to support camera operation without laying cables.

Challenges of Cost and Concept Renovation Currently, energy-saving products on the market are getting more and more attention, among which industrial customers and large-scale enterprises are the main ones. Small-sized enterprises and general household users have relatively little attention to this issue. Most users only stay focused on the one-time purchase cost phase. The user’s purchase intention is not yet aimed at energy conservation. At present, domestic users have not yet formed awareness of energy-saving management of security products. Citizens’ awareness of energy conservation is generally weak. The audience often pays too much attention to the one-time purchase cost and ignores the operating costs in the later period.

Industry sources pointed out that there are three reasons why wind and solar hybrid power supply monitoring systems cannot be fully used in the market. First, the cost is too high. Compared with the original system, the cost is more than twice as high. This is the most realistic consideration for users, and it also directly leads to less optimistic market promotion; second, stability issues. It can be seen from some experimental cases that this type of energy supply has poor stability and is greatly affected by the environment. For the monitoring system related to social security, stability is the first one; third, there are differences in concepts. The concept of energy conservation and environmental protection of the people is still relatively weak, and these technologies are still not well understood. Even though some industry professionals have some understanding, it is still not clear whether the technology is mature or not and can operate independently without a backup power supply.

On the whole, the wind power supply technology conforms to the development trend of energy conservation and emission reduction of products in the global scope. From some actual application cases, in the forestry, grassland fire monitoring, highway road monitoring, GSM base station monitoring, desert oil fields and other areas of the wilderness monitoring, the use of scenery and other new energy power supply is more cost-effective, convenient, and fast. The prospects are very broad. However, this technology has not yet been perfected, and the industry still has concerns about its high cost and stability. In areas where urban power supplies such as city surveillance are more convenient, the cost of using wind power is relatively high, and currently there is no price competitive advantage.

Standardization of energy conservation will become a security trend. Energy conservation has become a global consensus, and security is the responsibility of energy conservation. What is certain is that in the future, energy conservation will become a new standard for measuring the technical content of security products. The facts prove that this market trend is very obvious.

Some experts predict that in the near future, energy-saving performance requirements of products will appear in specific security product standards, and the future product market will, to a large extent, be an energy-saving market. Experts pointed out that, first of all, as the cost of system materials is reduced, the cost of the new power supply method will be greatly reduced; second, the problem of stability will be solved continuously through technical improvement, and different product design schemes will be formulated according to different specific environments to ensure the The stability of the system; Third, people's ideas have changed. Under the promotion of the national energy conservation policy, the government attaches great importance to energy conservation and environmental protection work, and brings bright prospects for the promotion of energy conservation and environmental protection products and technologies in the security field.
