Description

Technical Field

[0001] This invention relates to equipment maintenance technology on cold rolling finishing and rewinding mills, and more specifically, to an electronic locking device for self-management safety control of cold rolling finishing mills and its usage method. Background Technology

[0002] The self-managed projects of the cold rolling finishing unit mainly refer to the projects undertaken by production operators (including production assistants), equipment inspectors (including operation and maintenance personnel), integrated operators and maintenance personnel, and integrated inspectors and maintenance personnel to inspect, maintain, and troubleshoot the equipment they operate or inspect.

[0003] The existing operating method involves installing a mechanical switch on the unit's control panel for locking and unlocking the equipment. Before starting a self-operated project, the equipment must be locked and a self-operated project warning sign must be hung to prevent accidental operation by other personnel.

[0004] The existing control method mainly uses "manual locking + hanging warning signs", which has the following problems:

[0005] (1) Human operation is prone to negligence: Manually locking and unlocking the self-reliant project tag requires the operator's active execution, which carries the risk of human negligence. If the operator forgets to perform these steps or performs them incorrectly, the equipment may start unexpectedly during the self-reliant project, causing a safety accident;

[0006] (2) Inability to prevent accidental operation by others: Manual power outages and the hanging / removal of self-reliant project signs rely solely on the operator's initiative and cannot prevent accidental or malicious operation by others. If other personnel accidentally operate or intentionally start the equipment, safety risks will still exist;

[0007] (3) Reliance on personnel memory and adherence to procedures: Manual power outages and the hanging and removing of self-reliant project signs rely on the operator's memory and adherence to safety procedures, which introduces human factors that may affect safety. If operators have not received sufficient training or do not strictly follow the procedures, safety accidents may occur.

[0008] Existing patent applications, such as Chinese patent application number 201811569071.8, disclose a tool cabinet for storing electrical tools, in which a facial recognition device is connected to the cabinet door's access control system, automatically opening the cabinet door through facial recognition. Patent publication number CN111723648A discloses a method and system for identity recognition in electrical work, installing facial recognition and fingerprint recognition systems on electrical equipment, triggering an alarm when personnel retrieve the equipment. However, the above patent technologies only disclose the application of fingerprint or facial recognition technology to alarms or open / close cabinet doors after identity recognition. Summary of the Invention

[0009] To address the shortcomings of existing technologies, the purpose of this invention is to provide an electronic locking device for safety management of self-managed projects in cold rolling finishing units and its usage method, so as to ensure the safety of self-managed project operations, avoid misoperation and errors in the self-managed project tag hanging and unhooking process, and replace the existing "manual locking + hanging self-managed project warning signs" operation process, so that the tag hanging and unhooking process will not have human deviation and prevent other personnel from misoperating.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0028] S3, The bidding process logic for the self-reliant project is written into the electronic locking device for safety management of the self-reliant project through a program.

[0029] S4. Before starting the self-reliant project, click the "Unlock" button on the tablet computer. The self-reliant project security management electronic locking device will determine the identity based on fingerprint or facial recognition. If the person is in the image or fingerprint database, a "Lock" confirmation button will pop up and the device will be automatically locked after confirmation. If the person is not in the image or fingerprint database, the self-reliant project security management electronic locking device will not perform any operation.

[0030] S5. After the self-reliant project is completed, click the "Unlock" button on the tablet computer.

Once all personnel's lock records have been cleared, the self-reliant project security management electronic locking device will automatically unlock the locked device. If the person does not belong to the image or fingerprint database, the device will remain locked.

[0031] This invention provides an electronic locking device for safety management of self-operated projects in cold rolling finishing units, along with its usage method. It features "fingerprint + facial recognition" functionality, includes a fingerprint and facial database, and displays real-time information such as "personnel and name" and "operation start time" for each self-operated project. It stores activity records and allows for querying both immediate and historical information. An expansion interface is provided for future upgrades, achieving goals such as safe production, safe maintenance, intelligent registration, and efficient querying. Using this electronic locking device for self-operated project safety management avoids procedural errors during the tagging process. Since it cannot unlock devices locked by individuals other than the registered owner, it greatly minimizes safety hazards caused by misoperation. The system can be expanded to network monitoring, allowing users to query the locking and unlocking status and records of the online locking terminal via an app or computer terminal, facilitating tracking and real-time monitoring of the locking process by management personnel.
