Design And Implementation Of Vehicle Anti-theft System Based On GPS And GPRS

The number of family car has greatly increased with the accelerating industrialization and the improved quality of our life.At the same time,the situation of vehicle stealing is becoming more serious,especially the stealing methods being constantly updated.So the problem of car security protection has become urgent to be solved.This thesis designs a vehicle anti-theft system based on GPS and GPRS by analyzing the research status of vehicle anti-theft devices.The system can realize the function of vehicle anti-theft,alarm and location tracking.as well as reliability and economy so that it can be widely applied to all types of vehicles.The vehicle anti-theft system includes vehicle terminal and vehicles’ security monitoring and management platform software.This thesis mainly focuses on the design and realization of the vehicle terminal.The vehicle terminal will adopt ARM STM32F103C8 single chip microcomputer as the core processor.The GPS module applies the NEO-6M chip to get the real-time information of the location.Additionally,GPRS module uses the SIM900 A module to complete the communication task between the owner’s phone and remote monitoring platform.The implement of the system’s main function is that the owner can check the position of his vehicle in real time through the phone and the platform.Meanwhile,combined with the sensor module and the alarm module,the alarm information will be sent to the owner immediately when the alarm occurs.The main tasks include hardware circuit design,PCB circuit board design and vehicle terminal software design.The hardware circuit part mainly contains system circuit,GPRS module circuit,GPS module circuit and monitoring module circuit.The software part mainly introduces the software implementation of two communication modes: short message communication and GPRS data communication,the software design of GPS module location information collection.Finally,through the test of the overall performance,the anti-theft system realized in this thesis can meet the requirements of vehicle anti-theft because of the fast response speed and high positioning reliability.
