Abstract

The invention provides a new energy automobile CAN bus data wireless transmission vehicle data recorder device. A double single chip microcomputer communication technology, an embedded Linux technology, a 3G technology, a GPS technology, a CAN bus collection technology, a USB technology and a WIFI technology are integrated, the new energy automobile CAN bus data wireless transmission vehicle data recorder device is used for collecting and monitoring new energy automobile data, enables CAN bus data, positioning information data and failure warning information data of a new energy automobile to be uploaded to a monitoring center in real time in a protocol format according with a national standard and a department standard through a 3G wireless communication network, and the monitoring center carries out storage and follow-up analysis on the received data. The new energy automobile CAN bus data wireless transmission vehicle data recorder device has a local storage function, can analyze control commands issued by the monitoring center, makes a corresponding response, and provides a basis for operation, supervision and data analysis of the new energy automobile.

Description

technical field : [0001] The invention discloses a vehicle-mounted recorder device for wireless transmission of CAN bus data of a new energy vehicle, which belongs to the technical field of complete vehicle control. Background technique: [0002] At present, the industrialization trend of new energy vehicles is becoming more and more obvious, but my country's new energy vehicles are in their infancy, and the related technologies of new energy vehicles are not perfect, and the performance of the whole vehicle is quite different from that of traditional vehicles. Moreover, many new energy vehicles in operation, such as electric taxis, electric buses, and electric buses for enterprises and institutions, mostly have harsh working conditions. Because of the problems of new energy vehicle technology and working environment, various bus failure errors often occur. If these error messages are uploaded to the vehicle controller, it may even mislead the vehicle controller to take wr...
