OULU Wind solar complementary power generation system provides power for road monitoring
At present, highway road cameras usually operate 24 hours a day. The traditional municipal power supply system is adopted. Although the power is small, it will also consume a lot of electric energy because of the large number. The use of traditional power supply system is not conducive to energy saving; Moreover, the cable of camera power supply is often stolen and the loss is large, which greatly increases the use and maintenance cost and increases the operation cost of expressway business units.
The application of wind solar complementary power generation system to provide power for road surveillance cameras not only saves energy, but also does not need to lay cables, which reduces the possibility of theft and effectively prevents theft. However, there will be bad weather conditions in China, such as continuous haze weather, less sunshine, wind power can not reach the wind power, and there will be no continuous power supply. The original municipal power line can be used to automatically charge the battery when the solar energy and wind energy are insufficient to ensure the normal operation of the system.
