Design of Monitoring System on Vehicle Safety
Abstract: In order to make drivers better master some of the vehicle safety performance indicators, the monitoring system on the vehicle safe driving was designed that took AT89C52 as the core of the microcontroller so as to measure some safety monitoring indexes on vehicle such as tire pressure, oil temperature, oil pressure, and so on. The system was mainly composed of detection module, MCU and display module. This design used single chip technology, A/D conversion technology and liquid crystal display technology, single chip AT89C52 which was the core controller, By collecting signals with the sensor and sending them to the microcontroller which processed those signals , then sending signals to the display module.The simulation results show that the system can real-time detect the automobile tire pressure, oil temperature and oil pressure, and its measurement accuracy is higher. In addition, the monitoring system has good stability, practicality and low cost.
