| With the expanding scale of urban transport systems, the number of cars increase rapidly, also the urban road traffic congestion,vehicle thefts and other issues will be increased, as a subject, the taxi is particularly prominent. In this case, real-time monitoring of the operational status of rental vehicles, the vehicle has become a reasonable scheduling management to improve transport efficiency and prevent incidents of banditry practical problems, but also to promote social development, energy conservation, protection of the natural environment of the real problem.This article is designed vehicle monitoring and management system based on CAN/GPRS, which combines a high precision GPS systems with a good real-time function and real-time GPRS packet switching technology, high efficiency, covering a wide range of features, achieving the monitoring center to monitor and manage the vehicle.First, the whole system needs analysis, the system is divided into different functional modules and gives hardware selection to support system.Secondly, through the CAN interface design and GPRS transmission protocol and analysis method, combined with the control chip control for GPS and GPRS and AES encryption, gives the car terminal location information collected and transmitted to the remote monitoring center.Third, given the realization of program monitoring center of each function. Based on the vehicle terminal and monitoring center to determine the transmission of data formats and protocols for data monitoring center receives research methods and storage methods, the monitoring center are given for different vehicle information management solutions.Finally, this whole system’s debugging and testing. |
