The embodiment of the invention discloses a vehicle-borne terminal detection method and device based on a CAN bus. After a vehicle-borne terminal receives the request message sent by detection equipment through a CAN bus, the data type of the data which the detection equipment asks to obtain is analyzed and obtained. Then the data corresponding to the data type is obtained and is sent to the detection equipment through the CAN bus such that the detection equipment analyzes the obtained data, and the operation state or fault information of the vehicle-borne terminal is obtained. By using the method, the state data of the vehicle-borne terminal can be obtained through the detection equipment, and the data is analyzed to obtain the operation condition of the vehicle-borne terminal. Especially when the vehicle-borne terminal is failed, the failure information and failure reason of the vehicle-borne terminal can be analyzed and obtained, thus the maintenance of the vehicle-borne terminal by a user or maintenance staff is facilitated, the failure information of the vehicle-borne terminal can be obtained without returning to a manufacturer, the maintenance efficiency of the vehicle-borne terminal is improved, and the maintenance cost of the vehicle-mounted terminal is reduced.
Description
technical field [0001] The present invention relates to the technical field of vehicle-mounted terminals, in particular to a method and device for detecting a vehicle-mounted terminal based on a CAN bus. Background technique [0002] The vehicle-mounted terminal is usually installed inside the electric vehicle, and is responsible for real-time detection of information such as the operating status of the electric vehicle, and uploads the monitored information to the monitoring and management center, which monitors and ensures the safe operation of the electric vehicle. The vehicle-mounted terminal communicates with other electronic control devices in the electric vehicle through a CAN (Controller Area Network, Controller Area Network) bus. [0003] If the vehicle-mounted terminal fails, the monitoring and management center will not be able to monitor the electric vehicle. In the prior art, when the vehicle-mounted terminal breaks down, the vehicle-mounted terminal can only b...
