Introduction:
The grounding monitoring system is mainly used to monitor the real-time static electricity protection status of the wrist strap and the equipment grounding. If there is an abnormality, it can report the fault location, number and category to the relevant operation or monitoring and management personnel in time and accurately to prevent static electricity hazards and operational safety in advance.
One host can monitor 4 wrist straps and 4 devices (including table pads) online at the same time.If multiple machines are online, real-time network monitoring can connect up to 50 hosts to work together.At the same time, the multifunctional ground monitoring system transmits each online wrist strap/ankle strap and device ground monitoring data information to the PC through the monitoring network in real time and records it for archiving. The management or inspection personnel can call and view at any time.The grounding monitoring system is a new product developed by our company in the field of anti-static. It can effectively monitor the grounding of production auxiliary tools and equipment. It allows real-time monitoring, alarming, recording, and querying of grounding. Its functions are comprehensive and powerful.

Working principle of intelligent grounding network monitoring:
Working principle of intelligent grounding network monitoring
Features of grounding networking system:
A host has 4 wrist straps and 4 device interfaces (including pads).
When using the networked online monitoring function, multiple machines are used in series, and the maximum number is 50.
Adopt resistive monitoring principle, double loop grounding to ensure reliable grounding of monitored objects.
The internal circuit of the host adopts photoelectric isolation technology to effectively separate the electrostatic ground from the equipment ground, which is more safe and reliable.
The alarm threshold can be adjusted according to the actual grounding warning standards in different occasions and regions.
The operator can remotely access the monitoring through the network, and dynamically monitor the wearing of the human wrist strap, the pad and the grounding of the equipment in real time.
Adopt buzzer alarm sound and LED indicator alarm and PC upper computer system alarm and record it.
Convenient installation, low maintenance and management costs, simple replacement and maintenance of accessories, and ready to use.
Grounding system networking and function introduction:
Grounding system networking and function introduction
Using diffuse reflection infrared automatic sensing device, when the human body is detected, the human body wrist strap is grounded intelligently.
The sensing device can be flexibly adjusted according to the position of the human body to reduce blind areas. The human body induction signal detection lasts for 2-3 seconds, which can effectively stop the flow of people and trigger the induction to cause false alarms.
Table mat/equipment grounding abnormal, host alarm + alarm light alarm + computer sound alarm.
The wrist strap is grounded abnormally, the wrist strap inserts the label alarm + host alarm + alarm light alarm + computer sound alarm.
Through the scene, alarm lights, and host computer software, according to the corresponding machine number and port (location information) of the alarm, the fault is eliminated and the alarm is eliminated. The state change at this time is recorded in the database and can be viewed or exported.
Intelligent on-site alarms, computer management and database storage can efficiently and reliably realize integrated intelligent management of factory ESD.
