There is a lack of technical association between the DCCS system's dispatch orders and the anti-misoperation system’s operation sequences, which can lead to discrepancies between operation sequences and dispatch order content, resulting in remote control or operational errors.
The offline anti-misoperation mode and handwritten logical formulas pose risks of empty or skipped operations; secondary equipment lacks anti-misoperation control measures; management control measures for grounding wires and unlock keys are incomplete.
The control measures for maintenance operations, such as safety measure verification, work scope authorization, maintenance work permits, maintenance switching tests, and maintenance process monitoring, are incomplete. This affects the quality and efficiency of operations and poses safety risks.
Based on microcomputer anti-misoperation technology, the safety management and control solution 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 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.

With digital two-ticket processing as the business hub, the system integrates the new power system's three zones and four layers, fully covering scenarios such as disconnector operations, maintenance, and O&M tasks, enabling online two-ticket processing, mobile operations, transparent information, and intelligent support. This promotes the deep integration of digital technology with equipment management throughout all processes and stages, improving team efficiency and ensuring the safety of on-site operations, thus supporting the digital transformation of power companies.
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.
To meet the anti-misoperation requirements of one-key sequence control in substations, relying on nearly 30 years of experience in anti-misoperation product development, the system achieves dual verification of sequence control anti-misoperation while introducing new features such as directional authorization unlocking, grounding wire status collection, and graded and zoned lock management. These improvements enhance the safety and efficiency of on-site operations.
JOYO advanced minicomputer-based anti-misoperation integrated operation system has evolved through three generations of substation microcomputer anti-misoperation technology, accumulating experience from over 40,000 substations. By introducing innovative design concepts and leading key technologies, it serves such functions as simulated operation, anti-misoperation interlocking, and operation ticket management. The system utilizes a computer key to unlock on-site equipment, receive, and transmit data, while various locks are used to interlock on-site equipment, preventing electrical misoperations and ensuring safe and controllable disconnector operations.
The intelligent 3D anti-misoperation system ensures safety management and control during disconnector operations, equipment maintenance, and routine inspections by utilizing 3D visualization of the work site, real-time personnel positioning, trajectory tracking, violation detection, and real-time voice alarms for risks. This system effectively prevents unsafe and non-standard operations, such as exceeding work boundaries, entering live bays by mistake, or misoperation of equipment, which provides strict control over personnel trajectories, work areas, and operational behaviors.

In line with the business needs for intelligent O&M under the power grid company's "centralized control station+unmanned substation+equipment ownership" model, a safe, stable, reliable, and user-friendly anti-misoperation system is developed for main and substations by leveraging key technologies such as "PMS interconnection, remote control (sequence control) constraints, operation permission management, and information monitoring" to support the new substation O&M management model, enhancing the safety management and control level of the regional power grid.
Focusing on on-site operation and inspection tasks, and adhering to the "three zones, four layers" design architecture, an intelligent ticketing and mobile operation application is built with the enterprise middle platform as the backbone. This solution enables online management of the two-ticket process, mobile operations, transparent information, and intelligent support. It promotes deep integration of digital technology with the entire process and every aspect of equipment management, enhancing team work efficiency and quality, ensuring on-site operational safety, and providing a foundation for the construction of digital teams.
