Through the analysis of the site we came to the conclusion that the whole system we use wireless bridge hybrid network Winncam wireless bridge 2.4 and 5.8, from point to point and point to multipoint network, set up three level wireless transmission network, which can smooth the audio and video in the network through the front-end equipment; we recommend using infrared network the camera, rear end accept can use a computer, but also can use the DVR DVR to use the decoding function. Finally, we can view and manage the entire system at the back end. The most extensive application of solar energy in the early stage is to heat water, and millions of solar water heaters are now available all over the world. The main components of the solar water heating system include three parts: the collector, the storage device and the circulating pipeline. In addition, there may be auxiliary energy device (such as electric heaters, etc.) used to supply without sunshine, in addition still may have forced circulation with water, with water level control device or control electric parts or temperature and received loads of pipeline etc.. According to the cycle of solar water heating system can be divided into two kinds:
On the direct use of solar energy in humans is still at the primary stage, mainly solar collectors, solar water heating systems, solar heating, solar power, solar wireless monitoring etc.. Along with the development of modern enterprise system in our country's popularization and deepening development of enterprise informatization construction unceasingly thorough, safety and prevention work for enterprises using digital video technology has been combined with the development of solar energy technology represent the general trend, the launch of the real Winncam zero wiring for wireless monitoring solution. (solar wireless monitoring installation renderings)In the modern industrial park, the implementation of video surveillance system, the security department can realize all-weather real-time video monitoring in the industrial park at the entrance, the main road, office buildings, such as perimeter wall sites; the relevant departments can understand the situation, strengthen campus security management, improve work efficiency; the relevant departments can real-time understanding of each monitoring point the leading enterprises in the office; using a desktop computer, you can keep abreast of the real-time status of each monitoring point, handling emergencies, can also record multiple days ago, tracking and analysis, in addition to the establishment of local network monitoring system, but also to focus on remote video monitoring of branches. The actual production of Zhongcheng labor discipline inspection at any time Trw Corporation employees according to the actual needs of the park, some difficulties to take power, we use Solar power supply, with reference to the relevant international standards and national standards, combined with the company's experience in the Industrial Park monitoring and accumulated, the preparation of this zero wiring solar wireless monitoring technology program.
1 natural circulation:This type of storage tank is placed above the collector. Water heating collector in solar radiation temperature rise, causing the collector and tank water temperature and have a different density difference, thus causing buoyancy, this is like a hot siphon, the water flow in the water storage tank and collector. Because of the density difference, the water flow rate is proportional to the solar energy absorbed by the collector. This kind of type is widely used because it does not need the circulating water and the maintenance is very simple.2 forced circulation:The water in the hot water system makes the water circulate between the collector and the water storage tank. When the water temperature at the top of the collector is higher than the water temperature of the bottom of the water storage tank, the control device can start the water to make the water flow. A check valve is arranged at the entrance of the water to prevent the nighttime water from being driven by the collector to cause heat loss. The flow rate of this type of hot water system can be known (as a result of the flow from the water), easy to predict performance, can also be calculated in a number of hours of heating water. As in the same design condition, the natural circulation has can gain higher water temperature strengths, but because it must use water, the water power and maintenance (such as Water Leakage etc.) and the control device of dynamic stop, damage easily water problems. Therefore, in addition to large hot water system or the need for a higher water temperature, the forced circulation, the general use of natural circulation water heater. Solar power system consists of solar cells, solar controller, battery (group). Such as output power for AC 220V or
