Anti-interference device and method

Abstract

An anti-interference device and method are provided. The anti-interference device comprises an anti-interference module and a control module. The control module is used for sending a working signal to the anti-interference module. The anti-interference module is used for receiving the working signal and controlling the working state of a first element according to the working signal. The first element is connected with the control module through at least one first connecting wire and the at least one first connecting wire is divided into at least two sections by an anti-interference material which is connected with the ground. The anti-interference module is also used for sending a backflow signal to the control module, and the backflow signal flows to the control module through the anti-interference material. An anti-interference method is also disclosed. According to the technical solution provided by the embodiments of the invention, the connecting wire between the control module and the anti-interference module is divided by the anti-interference material, so that the loop area of the backflow signal is reduced and the electromagnetic radiation interference generated in a circuit can be effectively reduced with low cost.

Description

technical field [0001] The present invention relates to the field of electronic technology, and in particular, to an anti-interference device and method. Background technique [0002] Nowadays, the whole equipment integrates more and more electronic and electrical equipment. For example, more and more electronic components are integrated into the interior of the car. In a small space environment, how to achieve compatibility between various electronic and electrical equipment is guaranteed. It is not interfered by the operation of other electronic and electrical equipment, resulting in its own work failure or abnormality, nor is it not interfered by other electronic and electrical equipment caused by its own operation, and the failure or abnormality has become a requirement of all automobile companies and related suppliers. important issues faced. In order to ensure the quality of the whole machine and the normal operation of various electronic components, automobile compan...

AI Technical Summary

Problems solved by technology

For example, the liquid crystal display (LCD) module in the vehicle product has strong interference, which will cause the whole machine product to fail to meet the EMC index requirements of the car company

[0003] However, there is no anti-interference technology with low cost and good anti-electromagnetic radiation interference effect in the prior art.
