An anti-interference device and method

Abstract

An anti-interference device and method. The anti-interference device includes: an anti-interference module and a control module; the control module is used to send a working signal to the anti-interference module; signal to control the working state of the first component, the first component is connected to the control module through at least one first connection line, and the at least one first connection line is separated into at least two sections by the anti-interference material, so The anti-interference material is connected to the ground; the anti-interference module is also used to send a return signal to the control module, and the return signal flows to the control module through the anti-interference material. The corresponding anti-interference method is also disclosed. Adopting the technical scheme of an anti-interference device and method provided by the embodiment of the present invention, by using anti-interference material to separate the connection line between the control module and the anti-interference module, the loop area of ​​the return signal is reduced, and the low-cost And effectively reduce the electromagnetic radiation interference generated in the circuit.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an anti-interference device and method. Background technique [0002] Today's complete machine equipment integrates more and more electronic and electrical equipment, such as more and more electronic components in the interior of a car. It has become the requirement of all automobile companies and related suppliers to be free from the interference caused by the operation of other electronic and electrical equipment, causing their own work failure or abnormality, and not to be free from the interference caused by their own operation to other electronic and electrical equipment, resulting in failure or abnormality. important issues to face. In order to ensure the quality of the whole product and the normal operation of each electronic component, automobile companies have formulated their own very strict electromagnetic compatibility (Electro Magnetic Compatibility, EMC) standa...

AI Technical Summary

Problems solved by technology

For example, the liquid crystal display (LCD) module in the car 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.
