The trend of security concept of energy saving is obviously demand and trend

Foreword: In recent years, global energy issues have attracted more and more attention. Therefore, more and more security companies have gradually discovered that energy-saving security products will become the development trend of the security industry in the future. Energy-saving products are both a market demand and a market trend. Now that some security companies have begun to engage in the research and development of energy-saving products, energy conservation has become a consensus in the industry. What is certain is that in the future, energy conservation of products will become one of the new standards for measuring the technical content of security products. The facts prove that this market trend is very obvious.

The energy-saving trend of security is obviously the demand is also the trend 1. The energy-saving effect of video storage is obvious With the increase of hard disk capacity, the required power of the hard disk is also increasing. 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.

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.

2. Application of Energy-Saving and Energy-Saving Scenery The expressway streetlight system that is currently under construction has taken full advantage of green clean energy, and is powered by wind-solar hybrid systems, achieving zero power consumption, zero emissions, and zero pollution. Complementary wind and solar power refers to the complementary generation of wind energy and solar energy. This system uses solar cell arrays and wind turbines (converts alternating current into direct current) to store the electric energy generated by wind and solar power generation into the battery pack. When the user needs electricity, the inverter The device converts the stored DC power in the battery pack to AC power, which is sent to the user's load via the transmission line.
