GPS vehicle monitoring system The vehicle monitoring system composed of GIS and GPS technology can be divided into three major functional modules, namely: vehicle terminal module, mobile communication system and monitoring center. The vehicle-mounted terminal calculates the positioning data (longitude, latitude, time, speed, direction) and status data through the satellite signal received by the GPS receiver. After calculation and packaging, the data information is sent back through the wireless communication network (GSM/GPRS) Central information gateway, the central information gateway receives the positioning and status data from the on-board unit back to the center, judges the data type, and dispatches the GPS positioning data, status data, service requests, etc. to the corresponding monitoring unit according to the vehicle service unit of the central service system Client, monitoring client software based on the latitude and longitude coordinates in the uploaded ePs positioning signals of each vehicle, supported by the geographic information system, through electronic map matching technology, real-time display of the vehicle's position, status and other information on the map, thus achieving Real-time monitoring and management of vehicles. Mobile phone positioning vehicle monitoring system The mobile phone positioning vehicle monitoring system uses the driver's mobile phone with the vehicle to realize vehicle monitoring based on the base station positioning of the mobile operation network. Base station positioning mainly uses the distance measurement of the base station to the mobile phone to determine the location of the mobile phone, also known as the LBS base station positioning method. Its accuracy depends to a great extent on the distribution of base stations and the size of the coverage area. The urban area error is about 50M-200M. The suburban area sometimes has an error of 1 to 2 kilometers. The positioning accuracy can meet the needs of the logistics industry. It is widely used in the management of freight vehicles in the logistics industry. For example, as long as the driver’s mobile phone number is registered and the signal is turned on, the location of the mobile phone can be locked, and the data is fed back to the electronic monitoring center. On the map, logistics dispatchers can monitor freight vehicles in transit. Compared with the GPS positioning system, it does not require the installation of GPS and other equipment, reducing expenses, and is very popular with the management personnel of logistics enterprises.
