Abstract

The invention discloses a signal detection method and a detection device, comprising: obtaining configuration information for configuring a target controller to send messages on a CAN network and test item information for detecting test signals; according to the configuration information and the obtained Said test item information, build test case and set up test environment; Run said test case in said test environment, obtain the detection result to said test signal. The embodiment of the present invention is optimized on the basis of the traditional signal detection method, and solves the problems of poor compatibility, functionality and automation of the existing detection method.

Description

technical field [0001] The invention relates to the technical field of network signal detection, in particular to a signal detection method and detection device. Background technique [0002] Pure electric vehicles use the Controller Area Network (CAN, Controller Area Network) as the main network to transmit data, and control the battery management system (BMS, Battery Management System), motor controller (MCU, MotorControl Unit) and vehicle controller ( VCU, Vehicle Control Unit) and other main modules, the CAN bus transmits data in units of messages, so the correct analysis and packaging of CAN messages is very important. However, during the operation of thousands of CAN messages, errors are unavoidable, so it is necessary to configure relevant detection devices to detect the network message sending and receiving configuration and signal processing. At present, there is no detection device suitable for the three controllers of the VCU, MCU and BMS, and the current detecti...
