Aiming at the requirement of remote monitoring and anti-theft system, a GPS/GSM based mobile phone remote vehicle monitoring and anti-theft system is developed. The system design contains two parts: hardware part and software part. On the hardware design, the STC89C52 chip is chosen as the main control chip, the u-blox NEO-6M chip is used as the vehicle position information module, and the GTIM900-B chip is adopted as the short message sending module. On the software design of the system, a single-chip microcomputer program, an analog serial port program, a GPS information processing program and a GSM short message sending program are implemented. In addition, the system has developed algorithms, including map displaying algorithm, speech alarming algorithm and short message trapping algorithm. When an abnormal moving distance exceeds 100 meters, the current vehicle position will be identified and displayed on the APP map of the mobile phone in real time for the vehicle owner, and the system will warning the owner that the vehicle has moved by speech alarming. The system is the low-cost, and can be applied extensively on the remote monitoring of personal vehicle and the remote trapping and location of the outside moving subject.
