With regard to the present society, dangerous things continue to occur. Every day, we can see from the news that such incidents occur. Solar warning lights can provide a certain guarantee for the safety of our roads. For the entire system, there are two operating methods: manual control and active control. . Under the condition of manual control, when the circuit is connected, the warning light starts to flash to remind the vehicle or pedestrians to pay attention. Under the active control state, the operation state of the warning light is controlled. When the daylight is good, the resistance of the photoresistor is small, the relay is disconnected, and the warning light does not shine. When the light is dark at night, the resistance of the photoresistor becomes larger, the comparator outputs a high level, the relay is closed, and the warning light flashes when it is energized to play a warning effect. The power supply unit, the light control unit, the main control MCU unit and the LED light-emitting unit are the four parts of the system. The system mainly uses a solar panel to charge the battery through the diode, and the battery is powered after being stabilized. The battery is powered by the battery at night or cloudy day. Solar warning lights provide a guarantee for the safety of the city. In fact, as we usually say, we cannot predict the occurrence of danger, but if we can do some security guarantees, will it reduce the incident? Produced? The outstanding function of the solar warning light must be able to exert its effect.
Solar warning light is suitable for urban construction and other aspects, it can play a warning effect on some vehicles and pedestrians. However, from the current situation, the solar warning light itself needs to be continuously improved, and the process of using it is a process of finding problems, which is also more conducive to the correction and compensation of the solar warning light.
