Monitoring system, control host and monitoring method for radiation anti-interference test

Abstract

The invention relates to a monitoring system, a control host and a monitoring method for a radiation anti-interference test, wherein the monitoring system for the radiation anti-interference test comprises a first conversion module, an interface board, a second conversion module and the control host, wherein the first conversion module can intercept CAN (Controller Area Network) transmission data and LIN (Local Interconnected Network) transmission data from a CAN bus and an LIN bus when a tested vehicle is subjected to the radiation anti-interference test; next, the CAN transmission data and the LIN transmission data are sent to the interface board; moreover, the interface board conveys the CAN transmission data and the LIN transmission data to the second conversion module; at the moment, the second conversion module converts the CAN transmission data and the LIN transmission data into a specific data transmission mode respectively, and then conveys the CAN transmission data and the LIN transmission data in the specific data transmission mode respectively to the control host; and in such a way, the control host can monitor the changes of the CAN transmission data and the LIN transmission data in real time. With the adoption of the monitoring system, the control host and the monitoring method for the radiation anti-interference test, when the tested vehicle is subjected to the radiation anti-interference test, the condition of the tested vehicle can be monitored.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a monitoring system, a control host and a monitoring method for radiation anti-interference testing. Background technique [0002] With the continuous increase in the number and types of automotive electrical equipment, the electromagnetic environment in the car is becoming increasingly complex. The electronic equipment and devices on the car, especially the semiconductor logic devices are very sensitive to electromagnetic interference, so it is very necessary to carry out the radiation anti-interference test on the vehicle in the dark room. In the past, when doing radiation anti-jamming tests in darkrooms, the test phenomena were transmitted to the control room for monitoring through the camera, for example, the camera was used to obtain the image on the dashboard, and then sent back to the control room for monitoring. However, the camera can only observe the phenomenon on the surface of ...

[0003] On the other hand, the phenomenon captured by the camera is judged by the human eye to see if there is any abnormality, and the long test time can easily lead to missed judgments.

Even if the abnormal phenomenon can be correctly judged, it is impossible to accurately locate the frequency point when the abnormality occurs, and it is difficult to find the problem point
