This system contains a series of functions, [4]such as, detecting, judging, policing and so on. It can detect weather automatically and the function of Automatic alarm. For example, when bus launch with the door opened, this system will alarm Automatic. Meanwhile this system apply the technology of Photoelectric sensor. It not only realizes the intensity of light collection but also judge the day and the night. The most important is that it could control of the gate light intelligent. The Photoelectric Sensors referred in this article is mon in laboratory, application is simple and its price is very cheap. According to the Different light intensity, it will form different resistance and output voltages. This system detects the day and night through the microcontroller judgment and gives the output signal of the way. Alarm circuit applies SOC control Buzzer to realize Automatic alarm. The system applies the STM32F103C8T6 single chip microputer Produced by STMicroelectronics, which has a lot of advantages. These include less power consumption, patibility, high stability. The chip is small, but includes the five internal ans pletely, which is one of the main characteristics of this kind of chip. It has internal program memory, data memory, a variety of interface circuit. It is patible. It achie
