With the continuous improvement of the organizational structure and production management requirements of electric power enterprises, the field of electric power error prevention will inevitably develop towards automation, high safety, high efficiency, and intelligence of control systems. How to comprehensively improve the efficiency of operation and inspection operations, and further improve the intelligent level of substation safety management and control is the key to the competitiveness of enterprises. The existing error-proof locking technology in the industry can no longer fully meet the new requirements for safe, efficient, and intelligent error-proof security management and control of power grid operations and power production operations. Currently, the unlocking operation of error-proof system equipment is basically completed by relying on error-proof computer keys, and in the process of one-key sequential control, there is no intelligent verification function for error-proof logic. In particular, there is an urgent need to upgrade to "comprehensive, complete, mandatory, and effective" in maintenance operations such as grounding wires and unlocking operations, as well as secondary equipment operations. Relying on technologies such as the Internet of Things, intelligent identification, intelligent sensing, and mobile APP, we can solve the current problem of error prevention in the process of imperfect error prevention functions, as well as in unlocking operations and maintenance operations. On the premise of ensuring the safety of sequential control operations and local operations, Comprehensively improve the intelligent level and efficiency of transportation and inspection operation control. Adopt intelligent identification technology for maintenance work areas to achieve locking control of substation maintenance work, misoperation prevention control of equipment on maintenance work surfaces, and improve secondary misoperation prevention.

The following is a case study of a power company's distribution box lock control upgrade scheme

Relevant problems and shortcomings of the original lock control system:

The battery requires regular charging and maintenance.

The carrying of the supporting PDA is not convenient.

Customized mobile phone wireless charging shell is not convenient for users. (NFC+wireless charging)

The unlocking sensing time is longer.

Our lock control plan:

Adopt our passive energy acquisition and unlocking module scheme

The core difficulties to be solved in this scheme are: the collected energy needs to meet the unlocking power, and key considerations need to be given to: lock structure, motor selection, antenna area, appropriate increase in volume, and reduction of metal environment interference in the lock structure.

Methods to shorten energy collection time: Increase antenna area, effective energy management, and increase anti metal processing to improve the success rate of unlocking different mobile phone drivers: NFC RF debugging, software architecture optimization

Currently, our company has made breakthroughs in the application of relevant technologies in the power industry:

Key management, tool management, warehouse management, protection supplies management, etc.

Operation tickets and work tickets are integrated into terminals such as work cards or mobile phones to achieve intelligent check-in, equipment maintenance, intelligent filling, and task submission.

Intelligent lock control intelligently manages the door locks of equipment rooms, power distribution boxes, base stations, and other facilities, achieving intelligent authorization throughout the operation, controllable behavior, feasible plans, and traceable tracks, improving efficiency and ensuring safety.

Unlock control: strictly limit the scope of unlock operations, and informatization record the unlock operation process and unlock content.

In the security of electric power production, power error prevention has always been an issue that people attach great importance to. Against the backdrop of the rapid development of the electric power industry, we have been committed to using various intelligent devices and technologies to ensure the safe operation of the electric power system, thereby improving the automation and intelligence of the electric power system to a higher level.
