Abstract

The invention discloses a composite signal detecting system and a detecting method based on CAN (Controller Area Network) configuration, relates to a detection technology and aims at solving the problems that a large quantity of manpower and time are needed in the traditional manual detection of an instrument main control panel. A computer in the composite signal detecting system realizes communication with a test command analysis module through a CAN bus; the test command analysis module sends an analyzed command to the instrument main control panel to be tested through a digital signal analysis module or an analog signal analysis module; and a detection module detects a response signal of the instrument main control panel to be tested and feeds the result back to the computer through the CAN bus. The detecting method comprises the steps that a test command is generated by the computer, the computer controls and sends the test command to an instrument to be tested, and the computer receives, displays and outputs a test result. The composite signal detecting system and the detecting method are applicable for detecting the main control panels of automobile instruments and the like.

Description

technical field [0001] The invention relates to a detection system and belongs to the field of modern electronics. Background technique [0002] The main control panel of the automobile instrument needs to be tested before assembly, and can be assembled only after passing the test. This kind of test usually uses manual operation to send signals to let the instrument display the state of response, so as to judge whether the instrument is functional or not. qualified. Using this method requires a lot of manpower and wastes time, which is very unsuitable for the requirements of modern industrial automation. [0003] Therefore, there is an urgent need for a fully automatic testing instrument that can save manpower and time and is suitable for modern industrial automation requirements. Contents of the invention [0004] The purpose of the present invention is to provide a CAN network-based configuration composite signal detection system and detection method for the problem th...
