With the development of science and technology, companies are paying more and more attention to the use of wrist strap monitors to control human static electricity, but the detection methods are relatively backward, and some even do not detect and directly replace them after a period of time. First, if it is broken, there is no way to know, and second, if the employee does not wear it properly, there is no way to know. This fundamentally does not play the role of controlling static electricity, but increases hidden dangers. In the solution we designed this time, we used a real-time online monitor to ensure that we know the human body static control status at all times, to ensure that an alarm is triggered when the wrist strap is broken or not worn properly, and to let the management personnel or production line personnel wear or replace the wrist strap in time through an external indicator light. This solution mainly realizes real-time monitoring of the dynamic changes of the wrist strap grounding circuit and displays it through an external indicator light, so as to achieve the purpose of timely discovery and elimination of unsafe hidden dangers.
Based on:
General Specification for Anti-static Inspection of Electronic Product Manufacturing and Application Systems (SJ/T10694-2006)
"Establishing an electrostatic control program - Protecting electrical and electronic components, devices and equipment" (ANSI/ESD-S20.20-1999) "Protection of electronic devices from electrostatic phenomena- General requirements" (IEC EN61340-5-1:2001)
Wrist strap monitor has:
The practicality and economy of the system: The wrist strap monitoring system adopts unified monitoring products, taking into account the advancement, scientificity, practicality and economy of the system.
Real-time alarm: As a product anti-static, it is required to have real-time alarm to achieve the purpose of not harming the product by static electricity. The alarm response time of this system is only 0~20MS
Timeliness: If the employee's wrist strap is not worn properly, the wrist strap itself is broken or there is a problem with the grounding of the loop, a real-time sound and light alarm will be issued.
The wrist strap monitoring system is designed according to the customer's needs and the requirements of modern anti-static technology for wrist strap monitoring systems. The functional design follows the principles of scientific structure configuration, technological advancement, product modularity and compatibility, and investment economy, and is closely linked to the system goals.
