The Hardware Design Of Multi-Mode Information Service Of Vehicle Terminal Based On BD

Urban transport system is the critical infrastructure of the city, and it plays a key role in the normal functioning of the city, social development, economic prosperity and quality of life of residents. With the transportation infrastructure and the rapid development of information technology, the complexity and the increasing congestion of the road traffic has become a serious problem for vehicle travel. Because the urban transport system is a complex system of a multi-target, multi-level, multi-factor, relying on the traditional approach to traffic management tools and services have been unable to meet the development needs of intelligent transportation, and also it is difficult to solve urban transport problems fundamentallyFrom the current situation, the existing traffic information systems depend on collecting information, then publish information via electronic message signs and radio. To some extent, although this pattern contributed to the development of traffic information, there are some inadequate in network of traffic information and interactive information, and car navigation mainly relies on GPS. So there are many instability and unsafe factors. Under the new historical conditions, the development of technology of internet of things and BD navigation system connects urban transport traffic information with travel vehicle together to form a traffic information service system with the wisdom and communicate ability, which is an effective way to solve urban transport services. It will further enhance the intelligent transportation, information technology level.The main work of the subject is to complete hardware design of intelligent multimode vehicle services terminal. Device will use our own intellectual property-based BD satellite positioning technology, and in the terminal it integrates the communication module of WIFI,2G,3G, GPS and BD satellite navigation module multimode so as to achieve innovation in the transport sector. This terminal can achieve connection between a vehicle and urban traffic information service system, and provide efficient interactive services, and allowing the vehicle to become elements of an intelligent transportation nodes, supporting relevant industry regulatory requirements to achieve coordination of travel of the vehicle and the road, the goal of harmony and unity...
