車載實時路況信息接收終端的設計與實現(xiàn)
[Abstract]:In recent years, with the development of domestic economy, the number of domestic cars has increased rapidly, followed by serious traffic congestion in cities. But even during the rush hour, not all urban roads are congested, and a considerable number of roads are still clear. Therefore, based on the research of embedded system, this paper puts forward a kind of vehicle-mounted mobile device which can receive real-time road condition information. The device solidifies the electronic map in Rom and connects to the traffic information server through GPRS. Displaying the received information on the electronic map can provide an intuitive road condition for the travelers. People can avoid the heavy traffic congestion and choose the appropriate route to solve the problem of travel difficulties. The development platform of this topic chooses to use the Linux Qt4.8.0, system content to divide into the road condition information sending server and the road condition information receiving terminal. The traffic information sending server consists of a PC machine connected to the Internet network and a traffic information sending program running on it. The program has a graphical interface and can broadcast according to different traffic information. The hardware of the terminal is based on the Tiny210V2 embedded development board of the friendly arm Company, and the GPS module and the GPRS module are added. The electronic map of the terminal equipment adopts the geographic data packet of MapInfo company. The MapInfo electronic map format is one of the most widely used vector map formats at present. This paper studies the vector map format of MapInfo. The third party open source C library Mitab is used to process the map data file of MIF format, and the electronic map of Lanzhou urban area is compiled by Qt. After that, the serial port reading and writing based on Linux operating system is studied, the GPS data extraction program is written, the GPS data is obtained through the serial port, and the positioning function is completed with the electronic map. Finally, the GPRS wireless communication network is used to analyze the received road condition information by using the monitoring events of Qt, and the road condition and detailed event information are positioned on the corresponding road sections, and the dynamic updating display of the road condition information on the electronic map is realized.
