[0002] Nowadays, private cars are becoming more and more popular. When a car opens its door, it is unable to give early warning to pedestrians and passengers. If the car door is opened directly without early warning, it is easy to scratch pedestrians and obstacles in front and behind, and even cause serious traffic accidents. Therefore, with the rapid development of intelligent cars, it is very necessary to prevent pedestrians and obstacles from colliding when the car door is opened. In order to improve the safety of cars, car door opening alarm products are also set in the existing technology, but they do not provide early warning and two-way prompts, and cannot be installed independently, and the replacement and maintenance costs are high, which requires technicians in this field to solve the corresponding technical problems.

If it is detected that the touch signals from touch plate 1 connected to the touch chip 1 and touch plate 2 connected to the touch chip 2 do not exist, detect whether the timer T7 is started. If the timer T7 is not started, start the timer T7. Then the microprocessor detects whether the timing of T7 is timed out. If the timing of T7 is timed out, the microprocessor enters a low power consumption mode to save energy and reduce power consumption. If there is no timeout, the microprocessor cyclically detects the status of LED1 indicator light and LED2 indicator light, and executes the flashing of LED1 indicator light and LED2 indicator light at an interval of T6 to prompt pedestrians, motor vehicles, and drivers and passengers in the car.

[0012] Furthermore, the T6 is 0.2S and the T7 is 30S.
