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.

A kind of based on CAN network configuration formula composite signal detection system, it comprises: computing machine, adapter, digital signal parsing module, simulating signal parsing module, CAN communication module, instrument master control borad to be measured, detection module and test command parsing module;

Computing machine is connected on the CAN bus through adapter; The test command signal receiving end of test command parsing module is connected on the CAN bus; The digital test order receiving end that the digital test order output terminal of test command parsing module connects digital signal resolution module and, the simulation test order receiving end of the simulation test order output terminal connection mode analog signal parsing module of test command parsing module; The digital test information output of digital signal parsing module connects the digital test information input terminal of instrument master control borad to be measured; The simulation test information output of simulating signal parsing module connects the input end of the simulation test information of instrument master control borad to be measured; The response message input end of the response message output terminal connection detection module of instrument master control borad to be measured; Detection module sends to this response message on the CAN bus through the CAN communication module as testing result;

Adapter receives detection signal on the CAN bus, and this detection signal is sent to computing machine.

Based on a kind of detection method based on CAN network configuration formula composite signal detection system, implementation step is:

Step 1, computing machine produce a test command, and this test command is sent on the adapter;

Step 2, adapter send to received test command on the CAN bus;

Step 3, test command parsing module are resolved the test command that receives on the CAN bus; If the test data in this test command is a digital signal; Then the test command parsing module sends to the digital signal parsing module with this test command, and execution in step four then; If the test data in this test command is a simulating signal, then the test command parsing module sends to the simulating signal parsing module with this test command, and execution in step five then;

Step 4, digital signal parsing module send detecting information according to test command and give instrument master control borad to be measured, and execution in step six then;

Step 5, simulating signal parsing module send detecting information according to test command and give instrument master control borad to be measured, and execution in step six then;

Step 6, detection module detect the response message of instrument master control borad to be measured, and this response message is sent on the CAN bus through the CAN communication module as testing result;

Step 7, computing machine receive testing result through the CAN bus after sending test command, and show output.

Advantage of the present invention is: what the present invention adopted is the method for full-automatic measuring instrument master control borad, has saved manpower and has shortened detection time greatly, thereby be bigger economic benefit and the social benefit of enterprise's acquisition.
