Speed is one of the basic reasons for vehicle accident. Many lives could have been saved if emergency service could get accident information and reach in time. Nowadays, GPS has become an integral part of a vehicle system. This paper proposes to utilize the capability of a GPS receiver to monitor speed of a vehicle and detect accident basing on monitored speed and send accident location to an Alert...
To ensure the security of the payment of Logistics vehicles, we design a specialized cash box based on GPS. The design combines GPS satellite positioning technology, GPRS communications technology, electronic locks and microcontrollers and other advanced technologies. This cash box on the logistics vehicle is characterized by opening designated locations, remote control, an alarm for abnormal state,...
This paper introduces the overall design of vehicle bus data acquisition and fault diagnosis system on the basis of OBD, focusing on its lower computer system and the upper computer system design principles. This system is based on the widely used CAN bus technology, to extract the vehicle's status or fault information. The CAN bus adopts the SAE J1939 protocol standards, maximize the superiority...
Recently, attentions are focused more on bus interior network application and the wireless bus-carry data transmission technology. For developing a remote monitoring system, three aspects of the system are discussed: the vehicle interior network configuration, the CAN/GPRS gateway realization and the remote monitoring server design. Described in the paper are the hardware and software design of the...
This article deals with several kernel technologies applied in vehicle information service. The technology referring to GPS (Global Positioning System), GPRS (General Packet Radio Service), GIS (Geographical Information System), and Computer Network etc, as we have studied, is believed to be able to construct a Vehicle Information Service System which faces the public. Synthesizing the technologies...
According to the defects of the GPS vehicle monitor system in the present market,a high concurrent and real-time GPS vehicle monitoring system is proposed. The entre system is based on a three-layer framework:the terminals,the interim database server,and the monitoring workstation. The monitor workstation is based on the MAPX platform,and the database server communicates with terminals through GPRS...
Based on the technology of GPS/GIS/GPRS, the airport support vehicle command and dispatch system is designed in this paper. The information transmission between the vehicle mobile termination and the monitoring control center is established. The function of graphic display and phonetic warning of the airport support vehicle's working process is realized.
The paper designs and implements positioning monitoring system for vehicle based on GPS/DR (Global Positioning System/dead reckoning) technology. It solves the deficiency that vehicle can not locate and monitor when GPS signal loses, and improves positioning accuracy. The system uses S3C2410A microprocessor as the core of the entire system modules. The designation of the whole system, hardware and...
Most of vehicle monitoring systems based on GPS and GIS technologies use SMS as their communicating means. SMS didn't have private channel and is difficult to extend to suit other data business, could not afford stable communicating in those systems in some special situations. Contrasting with SMS, GPRS is cheap, real time and is more stable, and more suitable for those systems. A vehicle monitoring...
This paper introduced the GPS/GPRS-based remote electronic monitoring and calibration system, as well as its working principle and system framework. Then the hardware structure and software designing of vehicle mounted unit were introduced. Next, we emphasize testing the reliability and speed of communications while refreshing the data of ECU through GPRS. As a conclusion, it quickly implements the...
Unifying the embedded system, the GPRS networking and the car license recognition technology, this article designs and realizes one kind of a embedded wireless vehicle management system which using the ARM9 microprocessor from the hardware and the software. In terms of the hardware, completed the design and connection of arm embedded system, video frequency gathering compression module and GPRS module;...
The paper lays out the design of intelligent bus movement monitoring system and station-reporting system. The paper consists of two parts: hardware and software. Hardware part puts forward in detail the design of the main circuit unit and introduces the application of GPRS module MC55. Hardware system uses S3C44B0 to control ISD25120 voice chip and LCD module after receiving data sent by GPS module...
Vehicle overspeed is an important reason for the traffic accident on the freeway and it is helpful and necessary to monitor the peccancy behavior of over speed. In this paper, design method of the overspeed wireless monitoring system based on GPRS (general packet radio system) is discussed, and the configuration of its hardware and software is introduced. The whole system consists of the subsystems...
Running red led is an important reason for the traffic accident at the intersection and it is helpful and necessary to monitor the violation behavior of running red led. In this paper, design method of the wireless monitoring system for the violation of running red led based on GPRS (general packet radio system) is discussed, and the configuration of its hardware and software is introduced. The whole...
Using a GPS to navigate, a guard locates a car theft and utilizes vehicle tracking that is, at present, widely employed. In this paper the terminal device using a microcontroller combines a GPS and a GSM/GPRS to make a portable and remote controlling device, and an embedded server is used as a transfer location server. In this way one accomplishes real-time vehicle trajectory monitoring. Clients can...
