A Bi-direction Guard System Design of Car Based on GPS and GSM

Currently, some commercial car guard systems have little function, large volume and high power consumption. In this paper, a low power consumption guard system is designed with MSP430 micro controller. The system combines GPS receiver module with GSM communication network. By receiving position information from GPS, the longitude, latitude, velocity and position of object are calculated. At the same time, some messages about position information are transmitted by GSM network or telephone. The bi-direction car guard system can be used to guard and localize position of car. It is of high performance-price ratio.
