Description

Technical Field

[0001] The present invention relates to the technical field of anti-static wristbands, and in particular to an anti-static wristband monitoring system based on intelligent sensing and wireless transmission. Background Art

[0002] In static-sensitive industries such as electronics manufacturing and semiconductor processing, anti-static wristbands are an important protective tool for operators to prevent electrostatic discharge from damaging products. However, traditional anti-static wristbands only have a simple electrostatic discharge function and cannot effectively monitor their own wearing conditions (such as whether they are worn correctly, whether they have fallen off, etc.) or the integrity of the grounding circuit. At the same time, the alarm will continue to sound after the person leaves the post and will not turn off automatically. Usually, the power is manually turned off, and after returning to work, only the anti-static wristband is connected, and the power is forgotten to be turned on, resulting in the loss of electrostatic protection. If the wristband is not worn properly or the grounding is poor, static electricity may still cause damage to precision electronic products, leading to problems such as reduced product quality and increased scrap rate.

[0003] Therefore, an anti-static wristband monitoring system based on intelligent sensing and wireless transmission has become an urgent problem to be solved. Summary of the Invention

[0004] The technical problem addressed by this invention is to achieve real-time, accurate monitoring of the wear and grounding status of an anti-static wristband, effectively improving the reliability of ESD protection and protecting employees from the hazards of static electricity during production. This reduces product quality risks caused by static electricity and prevents component loss due to static electricity. The system is suitable for various static-sensitive production environments and laboratories.

[0005] To solve the above technical problems, the present invention provides a technical solution: an anti-static wristband monitoring system based on intelligent sensing and wireless transmission, which mainly includes an anti-static wrist strap sensor module, a resistance sensor, a wireless transmission monitoring system and a monitoring host.

[0006] The anti-static wrist strap sensor module is located inside the anti-static wrist strap and contains a contact sensor that detects contact between the wrist strap and the skin. If the wrist strap is not worn correctly or falls off, the contact sensor detects and triggers an alarm.

[0007] Resistance sensor: Connects the anti-static wristband's grounding circuit to the workstation's built-in buzzer and / or additional LED warning light. The resistance sensor monitors the wristband's grounding circuit's resistance in real time. When the resistance exceeds a preset range, it triggers a buzzer and / or LED warning light, prompting the operator to promptly inspect and repair the grounding circuit.

[0008] Wireless Transmission Monitoring System: Connected to the anti-static wrist strap sensor module and resistance sensor, it periodically collects data from the resistance sensor and transmits it wirelessly (e.g., via Bluetooth, Wi-Fi, or radio frequency signals in a specific frequency band) to a monitoring host. The wireless transmission monitoring system also provides preliminary data processing and analysis, enabling digital management. It also records abnormal event information, including time, location, and operator, for subsequent tracing and analysis.

[0009] Monitoring Host: Receives data and abnormal event information transmitted by the wireless transmission monitoring system, and stores, analyzes, and displays it. The monitoring host can also send alarm notifications to relevant personnel based on preset rules to ensure that problems are handled promptly.

[0010] The advantages of this invention over existing technologies lie in its ability to fully automatically measure, warn, and provide real-time notification of poor grounding points through intelligent sensing and wireless transmission. This system offers ease of use, real-time online monitoring, high precision, and intelligent monitoring. It reliably ensures the proper operation of wrist strap grounding systems in anti-static (personal) work areas, effectively limiting the economic losses and personal safety risks associated with anti-static equipment failure in enterprises.

[0012] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", "vertical", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0013] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0014] The following is a further detailed description of an anti-static wristband monitoring system based on intelligent sensing and wireless transmission of the present invention with reference to the accompanying drawings.

[0015] Combined with attachment Figure 1 The specific implementation process of the anti-static wristband monitoring system based on intelligent sensing and wireless transmission of the present invention is as follows:

[0016] An anti-static wristband monitoring system based on intelligent sensing and wireless transmission, intelligent sensing monitoring system:

[0017] Anti-static wrist strap sensor module: The wrist strap online monitor is installed inside the anti-static wrist strap and includes a contact sensor for detecting the contact status between the wrist strap and human skin;

[0018] Resistance Sensor: Monitors the resistance of the wristband grounding circuit. This sensor allows online monitoring of the operator's wristband grounding system status. It can also monitor either equipment grounding or mat grounding. It provides audible and visual alarms and displays the wristband circuit resistance in real time, ensuring the employee's grounding system is functioning properly.

[0019] If the intelligent sensor monitoring system detects an abnormal situation (such as not wearing a wristband, excessive ground resistance, etc.), in addition to the workstation's built-in buzzer alarm, the on-site LED display monitors real-time monitoring (with an extended LED warning light). The sound and light alarm replaces the expensive and cumbersome daily wristband inspection and record keeping work.

[0020] Wireless transmission monitoring system:

[0021] The wireless transmission monitoring system is connected to the wristband sensor module and resistance sensor, periodically collecting data from the contact and resistance sensors and transmitting this data wirelessly (e.g., via Bluetooth, Wi-Fi, or radio frequency signals in a specific frequency band) to the monitoring host. The system then performs preliminary data processing and analysis to enable digital management. It also records abnormal event information (including time, location, and operator).

[0022] The anti-static wristband monitoring system, featuring intelligent sensing and wireless transmission, provides fully automatic intelligent measurement, early warning, and real-time notification of poor grounding detection points. Featuring ease of use, real-time online monitoring, high accuracy, and intelligent monitoring, it reliably ensures the proper operation of wrist strap grounding systems in anti-static (personal) work areas, effectively limiting the economic losses and personal safety associated with anti-static equipment failure in enterprises.
