The two-ticket issuance is done manually, using an outdated ticketing model that lacks graphical and intelligent ticket generation capabilities. This results in low operational efficiency and high error probability.
The process of ticket issuance and review is entirely dependent on personnel, lacking technical means for real-time status-based logical and safety measure verification.
The dispatch, PMS, error prevention, and other O&M systems are isolated from each other, lacking business coordination. This results in data gaps and redundant work during the workflow of the two-ticket process.
On-site operations still rely on paper tickets, with paper records and slow information circulation. Records require manual sorting and secondary entry, affecting operational efficiency, and the records lack timeliness.
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.
Through whole process
With two-ticket processing as the main construction line, the system integrates the new power system's three zones and four layers, connecting systems such as PMS, dispatching, centralized control, and anti-misoperation, achieving end-to-end two-ticket operation, simplifying business processes, improving operational modes, and enhancing operational safety.
Mobile operations
Focusing on the needs of front-line personnel, the system integrates business processes, mobile applications, and terminal interconnectivity to achieve online, mobile, and transparent production operations, enhancing on-site operational capabilities and safety management and control.
Intelligent business
The solution deepens the innovation in two-ticket business applications, introducing intelligent technologies such as semantic recognition, machine learning, expert knowledge bases, and network topology analysis to achieve intelligent parsing, ticket generation, and verification, optimizing application experience, improving work quality, capacity, and efficiency, and enhancing the sense of achievement at the grassroots team level.
Unified data maintenance
With the support of the power grid resource business middle platform and the data center, the solution promotes the unification of schematic model data for the anti-misoperation system in Zone I and the two-ticket application in Zone IV. This ensures a single data source for each dataset, addressing the challenge of maintaining data consistency and meeting the need for integrated data sharing.
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.

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.
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.
