Everyone knows that gps is a global positioning system, then the vehicle also has a gps monitoring system. Today, Xiaobian introduces the components and applications of gps vehicle monitoring. I hope everyone can learn more.

Gps vehicle monitoring composition 1: GPRS mobile communication network

Public mobile communication network---GPRS mobile communication network is the data transmission medium of the system. The positioning data of the vehicle and the driving status data are transmitted to the dispatch management center through the mobile communication network. The reason why the public mobile communication network is selected is mainly because it has the characteristics of wide coverage and low cost, and is very suitable for the transmission of vehicle positioning data. There are two major mobile communication networks in China, namely GPRS communication network and CDMA communication network (also called mobile phone network). China Mobile mainly operates GPRS network, and China Unicom operates GPRS network and CDMA network. The system uses the data channel of the mobile communication network for data transmission. The specific protocol is China Mobile's short message protocol and GPRS protocol, as well as China Unicom's short message and CDMA1X data protocol. These systems can support these systems. The public mobile communication network has fast data transmission and high reliability, which provides an ideal platform for data exchange of monitoring systems.

Gps vehicle monitoring component two: GPS global positioning system

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

The GPS system is a high-precision, all-weather and global radio navigation positioning and timing multi-function system established with the development of modern science and technology. It uses a satellite network of 24 artificial satellites located at a height of more than 20,000 kilometers from the Earth to continuously transmit positioning signals to the Earth. Any GPS receiver on the earth can instantaneously calculate the motion state of the measured carrier, such as longitude, latitude, altitude, time, speed, heading, etc., as long as it receives signals from more than three satellites. The positioning error of the GPS is within 10 meters, which enables the management center to know the position of the vehicle more accurately.

Gps vehicle monitoring composition three: GIS geographic information system

GIS (Geophysics Information System) system is a computer database management system established for acquiring, storing, displaying and querying positioning data. The required information and data are displayed visually and visually on the electronic map in the form of graphs or tables. It provides a good map environment for GPS satellite positioning, and can perfectly combine the spatial information with the processing of attribute information to display information such as the position status of the vehicle in an intuitive manner.

The electronic map of the GIS system adopts the vector method to query the vehicles in any specified area, and can display the information hierarchically according to the needs; it can be arbitrarily enlarged, reduced, and moved; the multi-window display monitoring on the same screen can be performed, or the target can be locked in a certain window. , automatic tracking, etc. For the management department, the combination of GPS and GIS can realize the command management objectives in real time intuitively and efficiently. For the vehicle itself, the combination of GPS and GIS, in addition to completing the enterprise management functions, can also effectively achieve self-navigation.

Gps vehicle monitoring component four: computer data processing technology

In the 666GPS vehicle monitoring system, it mainly uses database technology, local area network and wide area network technology, multimedia technology, computer communication technology and computer remote control operation and other computer technologies.

GPS equipment can calculate the vehicle's motion status information in real time around the clock, mainly: vehicle position (accurate to 10 meters), running speed (accurate to 0.1 m / s), running direction (accurate to 1 degree) and time information (accurately 1 second).

After the equipment is installed, it can be turned on 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 administrator can perform unified management and scheduling. The management center can command the GPS vehicle terminal to press the designated Requires automatic return location.

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

The application of GPS vehicle monitoring in reality

GPS vehicle monitoring, from the user's own monitoring of vehicles to specialized company services, the attention of relevant management departments has added momentum to the development of the industry, showing product differentiation, multi-level utilization of data, value-added advertising resources, overall insurance, cost reduction, etc. Aspect development pattern.
