Introduction to GPS system concept

　　Dangerous goods vehicle monitoring and dispatching system is a software and hardware integrated system integrating global positioning system (GPS), geographic information system (GIS) and wireless communication technology. It is mainly composed of three parts: vehicle terminal, wireless data link and monitoring center system. It can conduct unified centralized management and real-time monitoring and dispatching for vehicles.

　　The GPS monitoring and dispatching system for dangerous goods transport vehicles has the function of real-time dynamic monitoring of all weather and all route vehicles. It is mainly used for vehicle tracking, dispatching, supervision, history query, security alarm, vehicle file management and other purposes.

　　Powerful functions of accurate vehicle positioning, real-time monitoring and efficient dispatching;

　　Fast alarm processing mechanism to minimize losses caused by accidents;

　　Provide multiple monitoring methods, which can focus on monitoring specific areas and lines;

　　Compatible with a variety of vehicle terminals, giving users high flexibility in hardware selection;

　　It can simultaneously support multiple communication modes, including GSM/CDMA SMS, GPRS and trunking;

　　The system has a complete security and automatic disaster recovery mechanism to ensure the security and stability of the system;

　　Precise digital map and professional map service support;

　　The industry-leading high-speed 2DGIS and 3DGIS engines are particularly suitable for real-time monitoring systems.
