Abstract:
In order to prevent forest fire, a solar-powered forest fire-proof and alarm system is designed and realized in this paper with the power supply furnished by the energy of the solar-powered battery, which is not only eliminating the trouble of replacing the power supply, but also obtaining the advantage of environmentally friendly approach and convenience to install. When the solar cell module is charging the battery, the alarm will track the output voltage and current of the solar cell module to obtain the maximum power, thus, the battery could be fully charged with the fastest speed. The system takes STC12C4052AD as the main chip, and DC/DC converter circuit is designed. The smoke & temperature sensors are used to detect the fire, and it will be a high-decibel alarm. The fire-proof and alarm system can be applied in the forest with harsh terrain or areas where power line is hard to lay, and the system has practical and commercial value with low cost.
