The application of solar warning lights conforms to the development of modern society, and through solar warning lights, some things can be avoided to some extent. With the acceleration of urbanization, more and more urban construction and construction. In order to prevent accidents of passing vehicles and pedestrians, it is common to set up eye-catching construction signs at the construction site. Especially at night and when it is rainy, snowy, foggy, etc., the weather is more dangerous. It is usually necessary to turn on the warning light to ensure safety. Solar warning light, the circuit is powered by solar panels and batteries, with both manual and light control functions. In the automatic control state, after the dark, the circuit can control the warning light to automatically turn on, and make it work in the blinking state, and the warning light can be automatically turned off during the day. It can also be controlled manually, it can also be used during the day, easy to adjust, low cost and easy to use.
For the present society, dangerous incidents have continued to occur. Every day, we can see the accidents happening in the news. The solar warning lights can provide certain guarantees for the safety of our roads. For the whole system, there are two modes of manual control and automatic control. . Under manual control conditions, when the circuit is turned on, the warning light starts to flash, alerting the vehicle or pedestrians. In the automatic control state, thereby controlling the working state of the warning light. When the daytime light is good, the resistance of the photoresistor is small, the relay is disconnected, and the warning light does not flash. 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 is energized to start flashing, thereby playing a warning role.
The power unit, the light control unit, the main control MCU unit and the LED lighting unit are composed of four parts of the system. The system mainly uses the solar panel to charge the battery through the diode, and the battery is supplied with power after being regulated, and is powered by the battery at night or on cloudy days. 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 safety and security, will it reduce the accident? What happened? The good performance of the solar warning light is sure to play its role.
The solar warning light is suitable for urban construction and other aspects, it can play a warning role for some vehicles and pedestrians. However, from the current situation, the solar warning light itself needs to be continuously improved. The process of using it is also a process of finding problems, and it is also more conducive to the modification and supplement of the solar warning light.
