Some anti-misoperation unlock keys, step keys, and combination electrical interlock/unlock keys are not under management and are uncontrolled, allowing O&M personnel to use them easily.
Some unlock keys are managed by methods such as envelope sealing or drawer storage, which cannot fundamentally limit the use of unlock keys, and their use is not recorded.
Once the unlock key is obtained, the unlocking scope cannot be controlled due to the use of common lock cores, making it easy to enter the wrong bay and cause misoperation.
Unlock keys are simple in design and easy to duplicate, leading to misuse.
The UT-050 series intelligent unlocking key management machine uses electronic sealing technology and mobile internet technology to standardize the authorization of all unlocking keys and automatically store usage records. These technical measures ensure the proper management and use of unlocking tools (keys). It accurately records details such as the applicant, approver, reason for unlocking, key retrieval, and return, and enables key monitoring, remote control, and directional unlocking, eliminating human errors, standardizing the management of unlocking tools (keys), and ensuring the safety of on-site personnel as well as the O&M safety of power grid equipment.
Directional unlocking, controlled operation
Unlock specific equipment through task-based directional unlocking, ensuring unauthorized equipment cannot be unlocked.
Status monitoring, specified access
Multiple authorization methods ensure the safe use of keys while providing greater convenience.
Efficient approval, flexible authorization
Each key has a unique identity and can be monitored in real time to track its status.
Record archiving, closed-loop tasks
Key usage information is automatically recorded, and task flows form a closed loop through encryption algorithms.

With "safety and efficiency" as the goal, and "business collaboration" and "data integration" as the core, based on the requirements of one-click sequence control, intelligent substations, and centralized control station construction, the system adheres to the new-generation architecture of substation secondary products that are autonomously controllable and compliant with information security standards. It relies on new technologies such as "big data, cloud computing, IoT, AI, and intelligence" and introduces innovative applications such as intelligent sensing, intelligent ticketing, intelligent verification, and intelligent maintenance. This expands anti-misoperation control from primary equipment operations to secondary equipment operations, maintenance tasks, and O&M activities, achieving comprehensive anti-misoperation safety management and control.
Based on microcomputer anti-misoperation technology, the safety management and control system for substation operation and inspection targets every aspect of integrated O&M workflows, including switching, maintenance, and repair operations. Through process refinement and system applications, combined with existing innovative technologies, it establishes a platformized, networked, and intelligent substation O&M safety management and control system. This platform fully covers safety control for O&M and repair across multiple disciplines, effectively improving work efficiency, reducing operational costs, and enhancing power safety production levels.
Substations, power plants, and industrial and mining enterprises' tool rooms store various safety tools and equipment, including insulating gloves, insulating shoes, safety helmets, voltage detectors, and temporary ground wires. Due to the large number, safety tools are placed in disorder. As a result, a lot of time needs to be spent counting them during inspections. The management practices are outdated . The UT-7710 series intelligent safety tools and equipment management device can electronically identify safety tools and equipment, enabling online detection and intelligent lifecycle management of safety tools and equipment. The safety tool management device can be used independently or used with other systems to achieve advanced management of safety tool .
Establish a WAPI network in the substation to achieve full signal coverage in the area, and deploy a wireless intelligent grounding wire management system. This ensures safe access to the wireless network and enables real-time data collection of grounding pile status, transforming the original “virtual remote signal” of the grounding pile in the microcomputer anti-misoperation system into a “real remote signal.” This avoids unnecessary travel during grounding wire installation and removal and eliminates the risk of misplacing or failing to remove grounding wires. An intelligent grounding wire cabinet is deployed to ensure the proper storage of grounding wires and manage their usage based on ticket issuance.
Currently, many accidents in transmission and distribution lines are caused by grounding wire issues. While negligence during operation is one factor, the more significant reason is the lack of effective management of grounding wires in transmission and distribution lines. This solution utilizes intelligent monitoring devices installed on grounding wires to enable real-time data collection and uploading of grounding wire connection status and location. Through cloud services and a mobile app, it enables remote monitoring and management of grounding wire storage and usage information. An intelligent grounding wire cabinet is deployed to ensure the proper storage of grounding wires and manage their usage based on ticket issuance.
The intelligent lock control system for communication towers is designed for the intelligent management of tower company communication room and cabinet door locks. It uses mechatronic intelligent locks with remote and on-site unlocking, high lock safety, real-time status monitoring, and timely abnormal alarms. This system meets the needs of base station inspections, maintenance, emergency repairs, and process control, ensuring base station safety and improving O&M efficiency.
Thermal power enterprises are characterized by large-scale, densely packed equipment, complex processes, tightly coupled production, and multiple high-temperature, high-pressure, and flammable areas. Traditional management methods that rely on "human oversight + procedures" are insufficient to address the safety management challenges of on-site operations. In view of the content and risks of each operation stage in thermal power enterprises, and with the goal of ensuring the safety of personnel, equipment, and the operation process, the system adopts a "technical defense + human defense + material defense" management approach. By integrating digital technology with power plant operation management, it enables measurable, visible, predictable, and controllable operations, comprehensively manages operational risks, improves efficiency, and supports the construction of intrinsically safe intelligent power plants.
