Embodiment Construction
[0038] In order to make the purpose, advantages and features of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the drawings are all in very simplified form and not drawn to scale, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. In addition, the structures shown in the drawings are often a part of the actual structures. In particular, each drawing needs to display different emphases, and sometimes uses different scales.
[0039] As used in this specification and the appended claims, the singular forms "a," "an" and "the" include plural referents unless the content clearly dictates otherwise. As used in this specification and the appended claims, the term "or" is generally employed in its sense including "and / or" unless the content clearly dictates otherwise.

The present invention provides a grounding control method, a grounding control device and a readable storage medium, wherein the first switch is connected between the sensor and the shielding shell, and the second switch is connected between the shielding shell and the grounding point, and the first switch is controlled to be closed and The second switch is turned off, as the first grounding mode, if the noise value of the sensor is not greater than the set value, then maintain the first grounding mode; and if in the first grounding mode, the noise value of the sensor is greater than the set value, Then control the first switch to be turned off and the second switch to be turned on as the second grounding mode; furthermore, if the noise value of the sensor is not greater than the set value, then maintain the second grounding mode. With such a configuration, by measuring the noise value of the sensor in the first grounding mode or the second grounding mode, the form of interference received by the sensor can be identified; the grounding can be quickly switched by switching the first switch and the second switch modes to deal with different forms of interference. The identification method of the interference form is simple and the identification efficiency is high.
Description
technical field [0001] The invention relates to the technical field of signal transmission, in particular to a grounding control method, a grounding control device and a readable storage medium. Background technique [0002] With the gradual development of electronic technology in the direction of high speed, high precision, high reliability, high sensitivity, high power and weak signal, electromagnetic compatibility technology has been paid more and more attention by people. Especially after a large number of modern electronic technologies are used in artificial satellites, missiles, communication equipment and high-end manufacturing equipment, the problem of electromagnetic compatibility becomes more prominent. [0003] For example, for high-end manufacturing equipment such as lithography machines, the motion table is controlled by magnetic levitation, which itself is a magnetic field. In order to drive the motion table, many high-power motors are installed on the motion ...
