Description

Technical Field

[0001] The invention relates to the technical field of functional safety testing, and in particular to a software solution for turnout maintenance based on a full electronic interlocking system. Background Art

[0002] In the actual application of DDOC system, customers usually want to perform system maintenance on specific turnout equipment without interfering with the normal operation of other equipment. During maintenance, DDOC control of the turnout equipment must be effectively disconnected, and the power supply path related to it must be cut off to ensure the safety of maintenance personnel and the integrity of the equipment.

[0003] At present, the industry generally uses hardware external air interface switches to achieve this function, but this solution has significant shortcomings. First, the physical structure of the air interface switch is easily worn out during frequent operation, resulting in switch failure and high replacement frequency, which not only increases maintenance costs but also prolongs equipment downtime. Second, the installation and wiring process of hardware equipment is relatively complicated, usually requiring technicians to have certain professional skills, which limits the flexibility and convenience of operation.

[0004] More importantly, the use of hardware switches to control the disconnection of turnout equipment poses obvious safety hazards. The DDOC system directly uses 220V and 380V power supplies to drive the turnout circuit. Any operating error or equipment failure may lead to electrical accidents, seriously threatening the lives of maintenance personnel. The hardware switch is not sensitive enough in high-voltage environments and may not be able to cut off the power supply in time, causing maintenance personnel to face the risk of electric shock during operation or causing equipment damage.

[0005] In addition, the response speed of air-interface switches is slow and cannot meet the needs of rapid maintenance of turnout equipment in the event of a fault. For example, in an emergency, maintenance personnel need to quickly cut off the power supply to prevent safety accidents, and relying on hardware switches may cause delays and increase the possibility of accidents. This solution usually lacks intelligent control and cannot be effectively integrated with the monitoring and alarm mechanism of the DDOC system, further reducing the overall safety and reliability of the system.

[0006] Therefore, a software solution for turnout maintenance based on a fully electronic interlocking system is provided. Summary of the invention

[0007] The purpose of the present invention is to overcome the existing defects and provide a software solution for turnout maintenance based on a full electronic interlocking system, which achieves more efficient and safe maintenance operations by optimizing the maintenance process of turnout equipment.

[0008] The technical solution to achieve the above purpose is:

[0009] A software solution for turnout maintenance based on a fully electronic interlocking system, with ATS (Automatic Train Protection System) as the initiator of maintenance operations, MUC (Master Control Unit) as the intermediate coordinator, and DDOC (Execution Unit) as the executor of maintenance commands, including:

[0010] Step S1, the maintenance personnel selects the corresponding turnout on the ATS interface, enters the maintenance request and performs identity verification;

[0011] Step S2, after confirming the authorization, the ATS generates and sends a maintenance command;

[0012] Step S3, after receiving the maintenance command, the MCU parses the command content and then forwards it to the DDOC of the corresponding turnout;

[0013] Step S4, when DDOC receives the maintenance command, it immediately performs a power cut-off operation;

[0014] Step S5, after the power is successfully disconnected, DDOC generates feedback information, which is sent back to MCU;

[0015] Step S6, after receiving the success status feedback from DDOC, MCU will record the information and forward it to ATS;

[0016] Step S7, after confirming that the maintenance command has been successfully executed, the ATS will update the user interface to prompt the maintenance personnel that the system has entered the maintenance mode. The maintenance personnel will inspect and repair the turnout equipment while ensuring safety.

[0017] Preferably, in step S1, a maintenance operation command module is newly added to the ATS interface, and the maintenance personnel initiate a turnout maintenance request through the interface.

[0018] Preferably, in step S2, when the maintenance command is generated and sent, the timestamp and operator information of the operation are recorded.

[0019] Preferably, in step S3, the parsed command content includes the identification of the target turnout and maintenance instructions.

[0020] Preferably, in step S3, when the MCU forwards the parsed command content to the DDOC of the corresponding switch, it will monitor the sending process in real time.

[0021] Preferably, in step S4, the power cut-off operation includes monitoring relevant circuits.

[0022] Preferably, in step S5, the feedback information includes power disconnection status, disconnection time and related switch ID.

[0023] Preferably, in step S6, the MCU stores all relevant logs and status information.

[0024] Preferably, in step S7, in maintenance mode, the ATS will continuously monitor the turnout status, and if an abnormal situation occurs, an alarm will be immediately triggered and the maintenance personnel will be notified.

[0025] The beneficial effects of the present invention are:

[0026] 1) By intelligently controlling and disconnecting the power supply of the turnout equipment, the risk of electric shock and equipment damage caused by traditional hardware switches is avoided. When performing maintenance operations, maintenance personnel can work in a safe environment, reducing the possibility of personal injury;

[0027] 2) The newly added ATS maintenance operation command module enables maintenance personnel to initiate maintenance requests intuitively and conveniently, simplifying the operation process. Through a unified interface and intelligent authorization, it reduces the complexity of operations and improves the work efficiency of maintenance personnel;

[0028] 3) The present invention realizes real-time monitoring and status feedback of maintenance commands, ensuring that each operation step can be traced and recorded. ATS can instantly obtain the power status and maintenance progress of the turnout, enhancing the controllability and transparency of the maintenance process;

[0029] 4) In maintenance mode, it can quickly respond to any abnormal situation and trigger an alarm to notify maintenance personnel in time. This efficient fault response mechanism reduces potential risks and provides maintenance personnel with conditions for rapid response, thereby improving the reliability of the entire system;

[0030] 5) By integrating the functions of the three major systems, efficient coordination of turnout maintenance is achieved, reducing the time and resources required for maintenance. After confirming that the system has entered maintenance mode, maintenance personnel can quickly start work, thereby improving overall maintenance efficiency;

[0031] 6) The design of the present invention takes into account the diversity of different turnout equipment, and can be adjusted and expanded according to actual needs to adapt to future technological development and the access of new equipment. The flexibility of the system makes subsequent functional upgrades and maintenance easier;

[0032] In summary, the intelligent control and system integration introduced by the present invention in turnout maintenance have significantly improved the safety, convenience and efficiency of the maintenance process, provided a strong guarantee for the safe operation of the railway system, and promoted the modernization of railway equipment maintenance management.

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] like Figure 1 As shown in the figure, a software solution for turnout maintenance based on a fully electronic interlocking system is provided. ATS is the initiator of maintenance operations and is responsible for safety system authorization and turnout control. MUC is the intermediate coordinator, receiving maintenance commands from ATS and forwarding them to the corresponding DDOC system to ensure the accuracy and real-time nature of command transmission. DDOC is the executor of maintenance commands, executing maintenance commands from MCU, cutting off external power supply, and sending real-time status to MCU. It includes:

[0037] Step S1: After the maintenance personnel selects the corresponding turnout on the ATS interface, they enter a maintenance request and perform identity verification.

[0038] In the embodiment, a maintenance operation command module is newly added to the ATS interface, and maintenance personnel initiate a switch maintenance request through the interface.

[0039] Step S2: After confirming the authorization, the ATS generates and sends a maintenance command.

[0040] In an embodiment, when a maintenance command is generated and sent, the timestamp and operator information of the operation are recorded for traceability.

[0041] Step S3, after receiving the maintenance command, the MCU parses the command content and then forwards it to the DDOC of the corresponding switch.

[0042] In the embodiment, the parsed command content includes the identification of the target turnout and the maintenance instruction.

[0043] In the embodiment, when the MCU forwards the parsed command content to the DDOC of the corresponding switch, it will monitor the sending process in real time to ensure that the command can arrive smoothly.

[0044] Step S4: When DDOC receives the maintenance command, it immediately performs a power cut-off operation.

[0045] In the embodiment, during the power cut-off operation, the relevant circuits are monitored to confirm whether the current has been completely disconnected to ensure the safety of the maintenance personnel.

[0046] Step S5, after the power is successfully disconnected, the DDOC generates feedback information and sends it back to the MCU.

[0047] In the embodiment, the feedback information includes power disconnection status, disconnection time and related switch ID.

[0048] Step S6, after receiving the success status feedback from the DDOC, the MCU will record the information and forward it to the ATS.

[0049] In an embodiment, the MCU stores all relevant logs and status information to facilitate subsequent review and troubleshooting.

[0050] Step S7, after confirming that the maintenance command has been successfully executed, the ATS will update the user interface to prompt the maintenance personnel that the system has entered the maintenance mode. The maintenance personnel will inspect and repair the turnout equipment while ensuring safety.

[0051] In the embodiment, in maintenance mode, the ATS will continuously monitor the status of the turnout. If an abnormal situation occurs, an alarm will be triggered immediately and the maintenance personnel will be notified.

[0052] Through this integrated approach, every step in the maintenance process is standardized, ensuring that the operation steps are clear and traceable. This not only improves the safety of turnout maintenance, but also simplifies the operation process for maintenance personnel.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
