The GPS location service system is an integrated system established to strengthen the visual operation management of vehicles. Darma GPS location service system has a national patent of China. It uses GPS global satellite positioning technology, GIS geographical information technology, mobile communication technology, and computer processing technology. Monitor and scheduling management.

　　Through this system, you can understand the location, speed, driving status and other information of the vehicle in real time; you can realize the nearby scheduling, dangerous alarm, and asking for help; you can understand the historical driving status of the vehicle; Report. The construction of the vehicle monitoring and scheduling system makes the management of the vehicle more scientific and reasonable. While improving the management level, many unnecessary expenses have also been reduced.

　　The GPS system is the core factor of this system. Due to the existence of the GPS system, the car terminal can calculate the location of the vehicle in real time.

　　The GPS system is a high -precision, all -weather and global radio navigation positioning, and time -granted multi -functional system with the development of modern science and technology. It uses a satellite network that is more than 20,000 kilometers away from the earth and consists of 24 artificial satellites to continuously emit positioning signals to the earth. Any GPS receiver on the earth, as long as it receives a signal issued by more than three satellites, can instantly solve the motion status of the measured carrier, such as longitude, latitude, height, time, speed, and direction.

　　The positioning error of GPS is within 10 meters, which allows the management center to understand the location of the vehicle more accurately.

　　After the device is installed, it can be turned on for 24 hours. The vehicle information is transmitted to the management center through the wireless data network and displayed on the electronic map. The management center manager can be unified management and scheduling. The management center can order the GPS vehicle terminal as specified Require automatic return position.

　　Through vehicle monitoring function, on the one hand, managers can remotely realize the visual management of vehicle personnel; on the other hand, for the transportation industry, they can provide real -time cargo tracking and improve the service level of logistics companies.
