Description

technical field [0001] The invention relates to the field of vehicle information services, in particular to a vehicle information system based on Beidou communication. Background technique [0002] At present, most of the known in-vehicle information service terminals are for the purpose of navigation service, or transmit the positioning information of the vehicle to the monitoring center through the GSM or 2G network. The transmission speed of the 2G wireless network is relatively slow, and the transmitted data is relatively simple. However, with the improvement of vehicle safety requirements and the development of in-vehicle information services, the monitoring center not only needs to collect vehicle location information, but also needs to collect vehicle status information and carry out remote monitoring, diagnosis and control of vehicles, and the amount of transmitted data is huge. increase, higher transmission speed requirements; due to the existence of signal blind sp...
