Problems solved by technology

Due to the harsh installation environment of hydro-generators, manual inspection is difficult and dangerous. At present, it is hoped to use a dedicated inspection robot for hydro-generators to replace manual inspections.
However, there is a strong magnetic field interference around the hydro generator, and it is necessary to propose an anti-interference system and method for inspection robots in a strong magnetic field environment.

Description

technical field [0001] The invention relates to the field of anti-electromagnetic interference of inspection robots, in particular to a system and method for anti-strong magnetic field interference of inspection robots. Background technique [0002] The working environment of the inspection robot is often accompanied by strong electromagnetic interference. The main problem of electromagnetic interference is that it will cause the controller to run code jumps, clock loss, etc., resulting in unstable operation of the robot. Therefore, the key to anti-electromagnetic interference is the protection of the controller. The methods adopted include the metal shell equipotential body shielding method. Although this method has a wide range of applications, the effect in the prior art is general, and it does not involve internal to internal electromagnetic wave interference, anti-electromagnetic interference software parts, and anti-electromagnetic interference circuit design. .
