With the management objective of ensuring operational safety in petrochemical production processes, the system employs technologies and tools such as electronic workflows, digital access control, safety interlock devices, IoT sensor equipment, and mobile work terminals to ensure the correctness and mandatory nature of process operations, address common issues such as cumbersome paper-based management, non-standardized operations, and inaccurate feedback on site conditions, and improve the efficiency and safety of process production operations, while also advancing the digitalization and intelligent management of petrochemical production processes.
Product Advantages Standardized operation processes
The system standardizes the processing of operation tickets through electronic business workflows, eliminating the non-standard issues of traditional paper operation tickets.
Improved operation efficiency
The mobile app allows operators to view operation instructions and record the work process at any time, improving operational efficiency.
Enhanced operation safety
Digital permission management for mandatory interlocking ensures that only authorized personnel can perform correct operations, reducing the risk of misoperation and enhancing operational safety.
Record keeping and closed-loop feedback
The system records key parameters and operation logs during the process and provides closed-loop feedback, helping operators identify issues and make improvements, thereby improving operational quality and safety.
The system aims to ensure the correctness and completeness of energy isolation, safeguarding the safety of maintenance operations. Through electronic workflows, digital permission management, isolation lockout attachments, and mobile work terminals, the system effectively addresses common issues such as cumbersome paper-based process management, irregular isolation processes, and inaccurate feedback of on-site status during the energy isolation process. It improves the efficiency and safety of energy isolation, and promotes the digitalization and intelligence of petrochemical production management.
The system integrates cloud services, mobile applications, and IoT technologies to achieve comprehensive safety management of the production process. The system's business modules include operational safety management and control, personnel safety management and control, environmental monitoring, and equipment monitoring, covering positioning, safety training, intelligent inspections, environmental parameter monitoring, safety procedure execution, and emergency response. The overall system structure effectively integrates various safety controls, ensuring comprehensive safety management throughout the petrochemical production process.
The one-click sequence control system includes a one-click sequence control host, a double confirmation device for disconnect switches, a ground wire status collection device, a secondary equipment status collection device, remote control clamps, and remote control circuit breakers. It achieves full monitoring and control of primary and secondary equipment within the station, meeting the high-reliability requirements of misoperation prevention and double confirmation of disconnect switch status, providing safer and more reliable technical support for the implementation of one-click sequence control.
This system provides closed-loop control for the entire process, personnel, and elements involved in the operation, maintenance, and inspection of the power supply system in petrochemical enterprises. It enables intelligent O&M management, including safe operations, intelligent inspections, information monitoring, status warnings, and decision support. This ensures the safety of both personnel and equipment, achieves the goal of reducing manpower while improving efficiency, and offers data support for condition-based maintenance of equipment.
With data integration and business collaboration as the main focus, the intelligent O&M safety management and control system for the petrochemical industry enables comprehensive and intelligent management of petrochemical power supply systems, providing support for safety assurance, efficiency improvement, emergency response, and green energy savings. The system comprehensively controls unsafe behaviors of personnel and unsafe factors in equipment, ensuring the effective implementation of safety production regulations, eliminating equipment safety hazards, preventing accidents, and building a safety management system for the entire power supply O&M process.
To address the business needs of intelligent O&M under the "centralized control station+unattended substation+equipment owner system" model of power grid companies, the system utilizes key technologies such as "PMS interconnection, remote control (sequence control) constraints, operation rights management, and information monitoring" to address issues such as low efficiency of ticket preparation at the centralized control main station, lack of safety constraints in remote/sequence control operations, incomplete control information, and insufficient business coordination between systems. This supports the new substation O&M management model and enhances the safety management and control level of regional power grids.
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.
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.
