Embodiment 1

[0039] The method of the invention is used to collect the engine speed signal under the J1939 protocol and the actual rail pressure signal of the engine under the UDS protocol.

[0040] Step 1: The remote communication terminal receives and stores the configuration file sent by the remote data platform through the wireless network.

[0041]The configuration file includes a header (Header) and a parameter signal section (ParaList); wherein, the header includes a remote communication terminal type, an engine controller information access method, data file collection rules (1,2,1), CAN channel Acquisition settings (CAN channel identification is 2, CAN channel communication baud rate is 2, 1, 0, 0), other application layer functions reserved, etc.; parameter signal part includes signal unique identification code (DCW_U010501), signal name (engine speed , actual rail pressure), signal acquisition mode (send after passive request), upload mode (1,1,1), request address (18DA00F1), re...

Abstract

The invention discloses a remote communication terminal data acquisition method based on a configuration file. The method comprises the following steps: 1, the configuration file is received and stored by a remote communication terminal; 2, the remote communication terminal analyzes the configuration file based on the analysis format to generate an analysis signal; 3, the remote communication terminal generates a to-be-collected list according to the analysis signal, the to-be-collected list comprises engine parameters needing to be collected, and the engine parameters correspond to the engine signals; and 4, the remote communication terminal carries out data acquisition on the engine through the corresponding engine parameters according to the list to be acquired. According to the invention, the configuration file is used as a target carrier of the engine signal, so that various engine signal acquisition under different protocols is compatible.

Description

technical field [0001] The invention relates to an engine data acquisition method, in particular to a configuration file-based remote communication terminal data acquisition method. Background technique [0002] The various operating data of the engine are important reference indicators of engine performance, and also one of the important parameters to ensure the safe driving of the vehicle. There are many types and models of engines, and their parameter protocol interfaces are also different. When collecting engine data, SAE J1939, ISO27145, ISO14229, ISO15765 and other protocol application layer definitions are involved. For example: the remote acquisition remote communication terminal module applied to the National VI regulations can often only meet the specific regulatory requirements, and the necessary national standard parameter signals and acquisition CAN channels are written in the form of programs for software development and implementation. When the signal acquisi...
