Manual operations are prone to issues such as erroneous power disconnection and reconnection, live working, or accessing the wrong track, which poses safety risks.
Due to the continuous extension of subway operation hours, the maintenance window for vehicles is short, and the efficiency of manual grounding is low and time-consuming.
Traditional power outage, restoration, and vehicle maintenance rely on manual paper forms for ticketing, and the operation process lacks informatized management.
During the process of maintenance personnel climbing the inspection platform, it is difficult to promptly determine whether the catenary system is live, leading to insufficient safety assurance for personnel.
This solution, designed for the power supply and maintenance operations of urban rail transit depots, adopts advanced technologies such as IoT, big data processing, automation control, computer technology, and network communication. Through monitoring, early warning, and control, it establishes a unified safety management and control platform that covers comprehensive dispatching, point management, and maintenance safety interlocking. Guided by the maintenance process of the depot, it establishes closed-loop process control, achieving real-time protection and informatization throughout the entire process to meet the goals of safe, efficient, and intelligent O&M management.
Full-process safety management and control
It implements safety interlock control for each step, including power outages, voltage detection, grounding, and platform operations, ensuring the safety of both personnel and equipment.
Automated operation process
The system adopts automation technologies such as remote grounding, intelligent door control, electronic ticketing, and access management, significantly improving the efficiency of maintenance operations.
Visual operation supervision
It enables remote real-time monitoring of the site operations and the status of related equipment in the depot, allowing management personnel to easily and intuitively grasp the situation on-site.
Comprehensive safety warnings
The system utilizes warning lights and voice broadcasts to monitor the live status of the catenary system in real-time, providing comprehensive on-site anti-misoperation safety warnings.

The JOYO-H2 visual catenary grounding management system includes a backend management system, AC/DC visualized grounding devices, and three-position visualized isolation grounding devices. It is applied to various rail transit systems such as urban rail transit, intercity rail transit, and electrified railways for the automatic power-off and grounding operations of catenary systems. The system uses integrated primary and secondary intelligent switchgear, automatic power-off and grounding operations, remote visual supervision, online voltage detection of catenary systems, programmatic control, comprehensive safety management and control, and closed-loop workflow management to address the lack of intelligence in catenary equipment and low efficiency in disconnector operations. It enhances the efficiency of catenary disconnector operations while ensuring safety and extends the effective catenary maintenance time.
The safety interlock management system for vehicle depot maintenance operations considers power supply operations and vehicle maintenance safety, mainly addressing issues such as low efficiency in personnel-controlled power operations, paper-based management of work processes, and a lack of safety interlocks throughout the work process. The system leverages automated measures such as logical judgment, safety interlocking, intelligent door control, audio-visual alarms, and video surveillance to achieve comprehensive safety management and control throughout the entire process, from vehicle depot power shutdown and restoration operations to platform maintenance work. These technical measures ensure the safety of both personnel and equipment during operations.
The rail transit power operation safety production management system, supported by new digital technology, addresses current issues such as high operational risks, short work windows, low O&M efficiency, and heavy maintenance tasks. It strengthens safety management and control and improves operational efficiency across the entire range of operational, maintenance, and work scenarios, and builds a next-generation rail transit power O&M safety control system, covering the entire network and all processes.
The crew scheduling management system uses informatized methods to optimize the management of each aspect of crew management, including the compilation of driving plans, automatic scheduling, dispatch and return status of crew members, safety training and education, query statistics, and information announcements. This forms a complete information chain, achieving centralized analysis, dynamic transmission, and information sharing of crew data. It effectively improves crew work efficiency and optimizes production dispatching command processes, realizing precise command and refined management.
It is applicable to electrified railways, urban rail transit systems, or city rail transit lines powered by AC 27.5 kV, including mainline catenary systems, station yards, and depots (EMU depots). The solution enables automatic grounding operations during catenary system maintenance, remote visual monitoring, online voltage detection, operational safety management and control, safety interlocking, and closed-loop management of work processes. While ensuring safety, it significantly improves the efficiency of grounding operations and safety measure deployments, thereby extending the effective maintenance time for catenary systems.
By replacing conventional isolation switches, transfer switches, and visual grounding devices with a combination of intelligent isolation grounding switch devices, this solution can be applied to urban rail transit mainline catenary systems and various scenarios within depots, achieving a comprehensive visual and intelligent solution for catenary system switch devices. It significantly improves the efficiency of catenary system disconnector operations and the intelligence level of catenary system switch devices.
Suitable for urban rail transit mainline catenary systems, throat areas, and maintenance depots, this solution enables automatic grounding operations, remote visual supervision, online voltage detection, operational safety management and control, safety interlocks, and closed-loop process management during catenary system maintenance. It significantly improves grounding operation and safety measure deployment efficiency while ensuring safety, extending the effective maintenance time for catenary systems.
