With the rapid development of economy, the number of cars in society has risen sharply, and the problem of vehicle management and deployment in various units has become more prominent. At the same time, carjacking, car theft and other phenomena that endanger social order and affect social stability are increasing year by year. Vehicle safety monitoring and management system can not only help relevant units and individuals to dynamically control their own vehicles and improve their dispatching and management capabilities, but also help public security departments to improve their rapid response capabilities in cracking down on criminal activities and handling emergencies.

Working Principle The GPS vehicle monitoring system consists of three parts, namely: vehicle host, server and client. The vehicle-mounted host mainly determines the position of the moving target through the global positioning system (GPS) in the United States, and uploads data through the mobile communication network and the global Internet. The server receives and stores positioning data, and the client accesses the server through the global Internet to extract maps and vehicle positioning information, thus providing users with perfect services.
The GPS receiver installed on the vehicle calculates the current position of the vehicle according to the received satellite information, and the communication controller extracts the required position, speed and time information from the signal output by the GPS receiver, and forms a data packet by combining the information such as vehicle identity, and then sends it to the monitoring center through the GPRS network of the mobile operator. The server of the monitoring center receives the data from the vehicle-mounted machines, extracts the positioning information from it, and displays it on the electronic map of the monitoring center according to the car number and car group number of each car. At the same time, the system administrator of the control center can inquire about the running status of each vehicle and dispatch vehicles reasonably according to the traffic flow.
The principle of vehicle monitoring system determines that the reliable operation of the system depends on three networks: the global positioning system of the United States, the GPRS network of China Mobile, and the global Internet based on different operators.
The vehicle monitoring and management system is composed of on-board computer and monitoring and dispatching center, and its information transmission depends on public network system, without a separate network system, which saves a lot of maintenance funds.
Vehicle safety monitoring and management system runs in the effective range of GSM public network, and can effectively track and manage all vehicle-mounted targets within the roaming range of the network. The popularization of GSM technology will drive the synchronous development of vehicle safety monitoring and management system. The expansion of the network means the expansion of the actual tracking range.
Vehicle safety monitoring and management system adopts multi-level architecture, and the scale can be large or small. From the group to the family, real-time tracking management of different properties can be carried out for different whole. Simple equipment, moderate cost and convenient use.
The 666GPS vehicle monitoring system composed of GIS and GPS technology can be divided into three functional modules: vehicle terminal module, mobile communication system and monitoring center. Vehicle-mounted terminal calculates positioning data (longitude, latitude, time, speed and direction) and status data through satellite signals received by GPS receiver, and sends the data information back to the central information gateway through GSM/GPRS after calculation and packaging, and the central information gateway receives the positioning and status data from the feedback center of vehicle-mounted unit to judge the data type. According to the vehicle ownership unit of the central service system, the GPS positioning data, status data and service requests are distributed to the corresponding monitoring clients. With the support of geographic information system and electronic map matching technology, the monitoring client software can display the position and status of vehicles on the map in real time according to the latitude and longitude coordinates in the ePs positioning signal uploaded by each vehicle, so as to realize real-time monitoring and management of vehicles.
The on-board monitoring framework consists of on-board terminals, transmission networks and monitoring centers, which provides functions such as vehicle theft prevention, robbery prevention, driving route monitoring, real-time wireless transmission of video images inside and outside the vehicle, rapid accident response, call command and so on, and solves the dynamic management problems of existing vehicles.
Vehicle-mounted monitoring adopts vehicle-mounted video server and 3~4 cameras. The video server is connected to the EDGE/cdma2000 1x/Wi-Fi network, and the monitoring center can monitor and transmit the images in the car in real time, using the dual code stream technology. Local video recording adopts D 1 resolution, and network transmission adopts CIF/QVGA/QIF resolution to realize local coded storage and remote storage.
Vehicle monitoring system is mainly composed of vehicle terminal (vehicle video server), monitoring center and transmission network.
Vehicle-mounted terminal Vehicle-mounted terminal is the front-end equipment of vehicle monitoring and management system, which is generally installed on various vehicles in secret. Vehicle terminal equipment is mainly composed of vehicle video server, LCD touch screen, external camera, telephone handle, car burglar alarm and other external equipment.
The vehicle-mounted video server collects audio and video signals, compresses them into digital streams, and transmits them to the user monitoring center through wireless networks such as cdma2000 1x, so as to achieve the purpose of remote monitoring and emergency command. In-vehicle video server needs to encode dual code streams at the same time, including local independent video streams and network streams.
Users need to extract video surveillance data in two ways: one is through the USB port of the vehicle terminal, and the other is through EV-DO(cdma2000 1x, Wi-Fi).
Monitoring Center The monitoring center is the core of the dispatching command system and a remote visual command and monitoring management platform. Monitor all vehicles at the scene to realize audio-video interactive command. The electronic map of the monitoring center can display the intuitive position of the vehicle, and the vehicle can be monitored and set up through the wireless network. For example, by configuring the pan/tilt, the vehicle-mounted front-end camera can be remotely controlled.
