Abstract

The invention discloses a configuration method and device for collected data of a vehicle-mounted terminal. The vehicle-mounted terminal is used for collecting data of two ECUs, the two ECUs comprisea master ECU and a slave ECU, and the method comprises the steps of acquiring configuration information; configuring data sending channels of the master ECU and the slave ECU according to the configuration information based on an XCP or CCP protocol; performing data acquisition on the master ECU and the slave ECU configured with the data sending channel through a CAN bus; distinguishing whether the acquired data information is from the master ECU or the slave ECU based on the interface number of the CAN bus; and storing the data information of the distinguished data sources in a database. Theproblem that the storage synchronism of the two vehicle-mounted terminals to the acquired data is difficult to guarantee when the two vehicle-mounted terminals acquire the dual-ECU data in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular, to a method and device for configuring data collected by a vehicle-mounted terminal. Background technique [0002] A vehicle-mounted terminal in the related art can only collect XCP data of one ECU, and the vehicle-mounted terminal only needs to receive and process the data sent by the CAN bus, and the vehicle-mounted terminal does not need to perform any processing. Two vehicle-mounted terminals are required to collect dual-ECU data, but it is difficult to guarantee the synchronization of the two vehicle-mounted terminals for storing the collected data. [0003] In the related art, when two vehicle-mounted terminals collect data from dual ECUs, it is difficult to ensure the synchronization of the data stored by the two vehicle-mounted terminals, and no effective solution has been proposed yet. Contents of the invention [0004] The main purpose of t...
