Abstract

A multifunction monitoring system of earthing comprises earthing detection unit including wrist belt detection module with insertion- start sub module and detection comparison sub module, platform pad detection module and equipment detection module; and indication unit for indicating detection information of earthing. The device can be used to monitor earthing state and static voltage of wrist belt, platform pad and equipment.

Description

technical field [0001] The invention relates to a signal device, in particular to a multifunctional grounding monitoring system. Background technique [0002] With the increasing electrostatic sensitivity of electronic components used in electronic products, the requirements for electrostatic control in electronic product manufacturing environments are becoming more and more stringent, requiring the grounding of workbenches, human body grounding and instrumentation in electronic product production environments. Monitor the grounding to ensure the reliability of its grounding, and monitor the leakage of equipment, workbenches, and the electrostatic voltage of the human body to ensure the safety of electronic products during production and assembly activities. Therefore, in the production of electronic products with high electrostatic sensitivity, it is necessary to monitor the grounding condition and leakage problems of the production environment. [0003] The existing groun...
