Mobile dvr 3g gps Introductions of Vehicle monitoring system:
The vehicle monitoring system is a combination of terminal data collection technology, mobile communication technology and Internet technology. Then it feedbacks the position and status of the vehicles to the software management persons. Through the system, vehicles can be located, tracked, monitored, etc It can export relevant data information as the historical basis of the vehicle travel. It can help the dispatching person to control the in-transit information of the vehicle, and finally improve the vehicle management efficiency

The types of vehicle monitoring systems:
GPS vehicle monitoring system
The vehicle monitoring system consisting of GIS and GPS technology can be divided into three functional modules, ie: vehicle terminal module, mobile communication system and monitoring center. The vehicle terminal calculates the positioning data (longitude, latitude, time, speed, direction) and The data information received by the GPS signals, and the and the packs the data information back to the wireless communication network (GSM/GPRS). The central information gateway receives the positioning and status data from the on-board unit return center, Determining the data type, and distributes the GPS positioning data, status data, service request, etc. according to the vehicle belonging unit of the central service system to the corresponding monitoring. The client and the monitoring client software realize the real-time display of The position and status of the vehicle on the map through the electronic map matching technology according to the latitude and long Degree coordinates in the uploaded ePs positioning signals of each vehicle, and supported by the geographic information system. Real-time monitoring and management of vehicles.
Mobile phone positioning vehicle monitoring system.
The mobile phone positioning vehicle monitoring system utilizes the driver's on-board mobile phone to realize vehicle monitoring based on the base station positioning of the mobile operation network. The base station positioning mainly uses the base station to measure the distance of the mobile phone to determine The location of the mobile phone, which is also called the LBS base station positioning method. Its accuracy depends largely on the distribution and coverage of the base station. The urban error is about 50M-200M, and the suburban 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 logistics industry of freight vehicle management. For example, the Lu Ge Guan Bao vehicle monitoring system only needs to register the driver's mobile phone number, And when the signal is turned on, the position of the mobile phone can be locked, and the data is fed back to the electronic of the monitoring cente r. On the map, the logistics dispatcher can monitor the freight vehicles in transit. Compared with the GPS positioning system, it does not need to install GPS and other equipment, reducing expenses, and is very popular among logistics management personnel.
