[Abstract]:This paper first introduces the background of GPS positioning system and the current situation of development at home and abroad, and describes the specific related technologies involved in the research in detail. The GPRS wireless communication network is used to monitor and dispatch the GPS terminal vehicle in real time. The system involves the knowledge of GPS location technology, database storage and access technology, geographic information technology, computer network technology and data structure algorithm. The GPS vehicle location monitoring system studied in this paper is divided into three parts: mobile vehicle terminal DTU module, computer network, wireless GPRS communication network and database service center. The DTU module of vehicle terminal is initialized and installed, and the optimal network access scheme, virtual serial port debugging and wireless network protocol configuration are selected to build and perfect the whole system for its normal operation. The interface of the system is designed on the server side, the data format is analyzed and stored, and a reasonable searching and storing updating algorithm is designed. From the above work, the vehicle is monitored in real time, and the reasonable remote scheduling is carried out, and the information is added, modified, deleted, queried, and the historical track is observed at the same time. Due to the limitations of the existing conditions, this paper simulates the continuous transmission of information from multiple terminal GPS modules to the database server. The design method uses the Zip distribution and Poisson distribution to simulate the random transmission of GPS data from multiple data terminals DTU to the server. The research of GPS vehicle positioning system is related to the social and economic development. GPS technology has been applied in intelligent transportation control, logistics distribution of goods and positioning and navigation of cars and so on.
