The invention provides a vehicular multi-system monitoring device which comprises a monitoring chip and an analog chip which is electrically connected to the monitoring chip; the monitoring chip is integrated with a processor chip and a Nor Flash chip; the analog chip is connected with an automobile diagnostic interface through an SAE (Society of Automotive Engineers) J1962 diagnostic connector; the monitoring chip operates a data monitoring program and controls the analog chip according to an operating result to realize logic gating with the automobile diagnostic interface; and the monitoring of the vehicular multi-system running state is realized through a corresponding diagnostic protocol. According to the vehicular multi-system monitoring device provided by the invention, the monitoring chip and the analog chip are adopted for realizing vehicular multi-system monitoring; a great number of relay switching devices are omitted; product volume is greatly reduced; and product cost is reduced.
Description
technical field [0001] The invention relates to a vehicle monitoring device, in particular to a vehicle multi-system monitoring device. Background technique [0002] With the rapid development of China's auto industry and the continuous popularization of family cars, the huge market potential of life after cars has attracted widespread attention from all parties. After years of market development and popularization, the automobile fault monitoring system has been effectively developed. [0003] The driving monitoring equipment for individual customers has gradually entered the personal user market of family vehicles due to its small size, low price, easy operation, and versatility based on OBDII and EOBD system monitoring. But at the same time, because the traditional monitoring equipment is based on the OBDII and EOBD series protocols, it can only monitor the relevant power system, the data volume is small, and the function is simple, so it cannot make a more comprehensive...
