Introduction to the working principle of vehicle-mounted GPS monitoring system

With the rapid development of economy, the number of cars owned by the society has increased sharply, and the problem of vehicle management and deployment of various units is more prominent. At the same time, various phenomena such as carjacking and car theft that endanger public security and affect social stability are increasing year by year. The vehicle safety monitoring and management system can not only implement dynamic control of the vehicles owned by relevant units and individuals and improve the dispatching and management capabilities, but also assist the public security department to improve the rapid response capabilities to combat criminal activities and deal with emergencies.

The purpose of the vehicle safety monitoring and management system is to solve the problem of how to monitor the location, status and other dynamic information of the vehicles in real time in a large area, deal with the problems encountered in vehicle operation in a timely manner, improve the effective utilization of limited resources, and ensure the personal safety of drivers. At the same time, it can effectively monitor, provide emergency rescue and provide various information services for mobile targets with strong mobility and large numbers across regions.

Principle of GPS Vehicle Monitoring System

The GPS vehicle monitoring system consists of three parts, namely: the vehicle host, server and client. The vehicle host mainly uses the US Global Positioning Satellite System (GPS) to determine the location of the mobile target and uploads the data through the mobile communication network and the global Internet. The server receives and stores the positioning data. The client accesses the server through the global Internet to extract maps and vehicle positioning information to provide users with complete services.

The working principle of the system is as follows: the GPS receiver installed on the vehicle calculates the current position of the vehicle based on the satellite information received, and the communication controller extracts the required position, speed and time information from the signal output by the GPS receiver, combines the vehicle identity and other information to form a data packet, and then sends it to the monitoring center through the mobile operator's GPRS network. The server of the monitoring center receives the data sent by the vehicle-mounted machine and extracts the positioning information from it, and displays it on the electronic map of the monitoring center based on the vehicle number and group number of each vehicle. At the same time, the system administrator of the control center can query the operating status of each vehicle and reasonably dispatch vehicles according to the traffic flow.

The principle of the vehicle monitoring system determines that the system must rely on three networks to operate reliably: the United States' global satellite positioning system, China Mobile's GPRS network, and the global Internet network based on different operators.

The vehicle monitoring and management system consists of an on-board machine and a monitoring and dispatching center. Its information transmission relies on the public network system, does not require a separate network system, and also saves a lot of maintenance funds.

The vehicle safety monitoring and management system operates within the effective range of the GSM public network. All vehicle-mounted targets can be effectively tracked and managed within the network roaming range. The extension of GSM technology will drive the synchronous development of the vehicle safety monitoring and management system. The expansion of the network means the expansion of the actual tracking range.

The vehicle safety monitoring and management system adopts a multi-level architecture, which can be large or small, and can carry out real-time tracking management of different natures for different entities, from groups to families. The equipment is simple, the cost is moderate, and it is easy to use.
