Automation Solutions for Industrial Safety Locks

1. Core Technologies of Intelligent Locks

• IoT Connectivity: Sensors (for open/close status, vibration, temperature, and humidity) and wireless communication modules (4G/LoRa/NB - IoT) are integrated. The lock status is uploaded to the management platform in real - time. Alarms are triggered automatically when there is an abnormal opening (e.g., forced entry or overdue unlocking), and notifications are sent via SMS. For example, in chemical plants, tank valve locks can be linked to the DCS system to lock valves and cut off remote control rights when abnormal pressure is detected.

• Contactless Authorization: Biometric recognition (fingerprint, iris, face) with an error rate of less than 0.001% replaces traditional keys, suitable for high - security areas. RFID/NFC smart cards provide one - card - one - permission access, and permissions are updated dynamically through the enterprise OA system.

• Automated Energy Isolation (Smart LOTO): When equipment is under maintenance, the system automatically generates electronic work orders, locks energy sources according to preset procedures, and displays virtual warning labels. After maintenance, locks are unlocked by scanning codes, and all data is archived, complying with OSHA 1910.147 and GB/T 33579 - 2017.

2. Typical Application Scenarios

• Unmanned Warehousing and Logistics: Locks on automated warehouse shelves and containers are controlled remotely by the WMS system. AGVs can access the locks automatically when they reach the designated positions, and the locks are self - checked and locked after the operation.

• High - risk Equipment Maintenance: Locks on wind turbine converter cabinets and photovoltaic power station junction boxes are linked to equipment status sensors. They can be locked automatically to prevent maintenance work under unstable conditions.

• Compliance Auditing Upgrade: Lock operation records are synchronized to the enterprise safety management platform, generating ISO 45001 - compliant audit reports for remote inspection by regulatory authorities.

3. Advantages and Value

• Efficiency Improvement: Permission changes are reduced from 2 hours to 5 minutes, and the standardization rate of equipment maintenance processes reaches over 98%.

• Risk Reduction: Safety accidents caused by human error are reduced by 70%, and the response time to lock failures is compressed from 4 hours to 15 minutes.

• Cost Optimization: Key management costs are reduced by 85%, the frequency of manual inspections in high - risk scenarios is decreased by 60%, and equipment downtime losses are reduced by 40%.

4. Core Standards and System Integration

• Communication Protocols: Support industrial - level protocols such as OPC UA and Modbus TCP for seamless integration with PLC and MES systems.

• Security Certifications: Pass environmental reliability tests like CE, UL, and GB/T 2423, and use financial - grade data encryption (AES - 256) to prevent data tampering.
