Circuit design of automobile anti-theft system
Abstract:The car anti-theft system is one of many anti-theft systems. It is widely used in various vehicle structures. Its main performance is the accuracy and stability of environmental recognition, the accuracy of alarms and the effectiveness of information transmission. As the most important anti-theft system in the market, the electronic car anti-theft system improves the accuracy and stability of environmental recognition, the reliability of alarm information, and the effectiveness of infrared information transmission. Using STC89C52 microcontroller as the core of hardware circuit control, external Sensor module and controlled module.The vibration and capacitance sensors are used to obtain external environmental information for the single-chip microcomputer, and the infrared sensor is used to realize infrared communication between the remote control and the single-chip microcomputer. According to the program in the single chip microcomputer, the electronic lock of the controlled component alarm is controlled. In order to achieve a fast response of the microcontroller to the sensor, the sensor information is input to the external interrupt of the microcontroller to achieve fast processing. Multiple interrupt responses are used to achieve fast and efficient control of multiple input information.
Keywords: car anti-theft; infrared communication; single chip; sensor
