3, Monitoring Center

The equipment composition of the monitoring center includes: database, monitoring terminal/GIS terminal, business processing terminal, and front -end access equipment.Staff can monitor the movement of all mobile targets through the network through monitoring the system.The key is the database construction, electronic maps, and application software-Mis, which is closely related to business content to achieve main functions such as vehicle scheduling, monitoring alarm, and information query.

The functions and characteristics of the GPS monitoring system

1As well asGPSMonitoring function

(1) Real -time video monitoring

The monitoring center can monitor the vehicle remotely in real time,GPSWireless video server (single card/ /Double card) Support multi -way video remote browsing.

(2) Video storage playback

(3.GPSAlarm linkage

GPSThe alarm linkage mainly includes an external alarm button, that is, the driver can report to the monitoring center when the driver encounters an emergency during driving.The second is two -way voice calls.

(4.GPSposition

built-inGPSYou can track the motion trajectory of the vehicle and fully understand the operation.

2As well asGPSMonitoring characteristics

The monitoring system supports monitoring through a variety of terminals, mainly includesPCWaiting for clients, TV walls, mobile phone terminals, and remote video browsing, remote control, multi -screen monitoring, manual video, video playback and other functions.

(1) Monitor the client

The monitoring center is connected to telecommunications through the dedicated lineIDCIn the computer room, customers can browse and cameras at each monitoring pointPTZControl and other functions.

(2) mobile phone monitoring

Monitor the client software through the built -in monitoring of the client software3GThe mobile terminal realizes remote video browsing, remote cloud mirror control, video screenshots and other functions to meet the needs of customers' remote video viewing and remote emergency command.3GCustomers provide video surveillance services anytime, anywhere.

also,GPSThere are other characteristics of monitoring.First, distributed monitoring, centralized management, intelligent settings, and humanized operations.The second is the integrated design of wireless video servers with high system reliability.The third is to adopt dual -code flow technology, local video adoptionD1Resolution, network transmission adoptionCIF/QVGAResolution.The fourth is to adoptH.264The method of compressing coding, support multi -road video access at the same time, each video is in8~10Frames, the video is clearer.Fifth, wireless network transmission, China Mobile3GThe upward bandwidth can be reached1.8mbit/sEssenceSixth, the system has strong expansion capabilities.

GPSThe monitoring and management system will be out of time, time, arrival time, return time, parking time, speeding time, fatigue driving, trajectory analysis, late management, outlet management, line management, mileage statistics, fuel consumption management, fuel consumption management, fuel consumption management, fuel consumption management, mileage, mileage, mileage.Data statistics and other businesses conduct report analysis.To realize the humanized management model, bring more returns to enterprises!"Vehicle Manager" monitoring and positioning system has become it3GThe mainstream of the times, it serves every car owner with the spirit of responsibility, trustworthiness, refinement, and innovation to solve the troubles of car use!

GPS vehicle monitoring composition

The vehicle monitoring structure consists of a three -layer network comprehensive regulatory system formed by the vehicle terminal, the transmission network and the monitoring center to provide functions of vehicle anti -theft, anti -robbery, driving route monitoring, real -time wireless transmission of video images inside and outside the car, To solve the dynamic management of existing vehicles.

The vehicle monitoring uses a vehicle installation of the car video server with 3 to 4 cameras.The video server via EDGE/CDMA20001X/Wi-Fi network. The monitoring center can monitor and transmit real-time monitoring and transmission of images inside the vehicle. It also uses dual-order streaming technology. Local video uses D1 resolution. The network transmission uses CIF/QVGA/QCIF to distinguish the resolutionRate, realize local coding storage and remote storage.

The main composition of the vehicle monitoring system is divided into: vehicle terminal (vehicle video server), monitoring center, transmission network, etc.

GPS vehicle monitoring system working principle

1As well asGPSThe vehicle monitoring system consists of three parts: car host, server and client.The car host is mainly through the global satellite positioning system of the United States (GPS) To determine the position of the mobile target, upload data through the mobile communication network and the global Internet, the server receives positioning data and stores it. The client access the server to extract maps and vehicle positioning information through the global Internet access server.

2, Installed on the vehicleGPSThe receiver calculates the current location of the vehicle based on the received satellite information.GPSExtract the position, speed and time information required in the signal output of the receiver, combine information such as the vehicle identity, and other information to form a data packet, and then through the mobile operatorsGPRSThe network is sent to the monitoring center.The server of the monitoring center receives the data sent by the vehicle machine and extracts the positioning information from it. According to the vehicle number and group number of each vehicle, it is displayed on the electronic map of the monitoring center.At the same time, the system administrator of the control center can inquire about the operating conditions of each vehicle and reasonably dispatch the vehicle according to the traffic flow.

3The principle of the vehicle monitoring system determines that the system needs to rely on three networks to run reliable: the global satellite positioning system in the United States, China Mobile, China MobileGPRSThe global Internet network based on different operators.

4The vehicle monitoring management system consists of the vehicle machine and the monitoring and dispatch center. The information transmission depends on the public public network system. It does not need to be established alone, and also saves a lot of maintenance funds.

5, Vehicle Safety Monitoring Management System is inGSMOperation within the effective range of the public network, all car targets can be effectively tracking management within the scope of the network roaming range.GSMThe extension of technology will promote the simultaneous development of vehicle safety monitoring and management systems.The expansion of the network means the expansion of the actual tracking range.

6The vehicle safety monitoring management system adopts a multi -level architecture, which can be large or small. From groups to families, they can conduct various types of real -time tracking management of different natures for different overalls.The equipment is simple, the cost is moderate, and it is convenient to use.
