[0002] Urban rail transit signaling equipment (hereinafter referred to as tronin signaling equipment) is the core equipment for ensuring train operation safety and efficiency. Regular maintenance is a prerequisite for maintaining its stable and reliable operation. Tronin signaling equipment has a complex working principle, and maintenance operations must strictly follow established procedures. However, existing maintenance standards mostly rely on written documents and verbal communication. The standardization of the operation process depends entirely on the responsibility and professional competence of the operators, which can easily lead to problems such as non-standard maintenance and omissions in procedures, resulting in equipment failure and affecting the normal operation of rail transit the following day. Although some auxiliary maintenance tools and equipment have been put into use, they still cannot achieve refined control over maintenance operations.

[0003] Based on the above situation, it is urgent to use digital and intelligent technologies to implement refined supervision and control over the standardization, omissions, and equipment status of urban rail signal equipment maintenance procedures, so as to improve the quality of the operation process, ensure that the equipment is in normal working condition before the next day's operation, avoid the risk of operation interruption and human error, and thus comprehensively improve the overall quality of maintenance operations.

[0028] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the monitoring method, apparatus, equipment, and medium for the maintenance of urban rail signaling equipment proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the embodiments of this invention. Please refer to the drawings to make the objectives, features, and advantages of this invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this invention, should still fall within the scope of the technical content disclosed in this invention.

[0029] This invention provides a monitoring method for the maintenance process of urban rail signaling equipment, comprising the following steps: S1. Predefine and configure the various model data and conditions required for the supervision of urban rail signaling equipment maintenance procedures, including: defining the main model of urban rail signaling equipment, the sensing data model and the alarm data model; formulating supervision rule models for various types of equipment; establishing the mapping relationship with the target equipment of the production planning management system; and specific equipment configuration.

[0030] Step S1 specifically includes the following steps: S1.1 Define the main model, sensing data model and alarm data model of the urban rail signaling equipment to lay the foundation for subsequent steps. The sensing data model includes the switching quantity, analog quantity and recorded curve of the equipment.

[0031] The urban rail signaling equipment includes, but is not limited to, turnout switch machines, ATS (Automatic Train Protection) equipment, ATC (Automatic Train Control) equipment, interlocking equipment, fully electronic interlocking equipment, axle counting equipment, and power supply equipment. Specifically, the main model for urban rail signaling equipment is defined by classifying the equipment according to its operational purpose through visual configuration, i.e., typifying it into several equipment types, and assigning a fixed equipment type ID to each type. Then, specific urban rail signaling equipment is instantiated to form a main equipment type list, where each instantiated device has a unique equipment ID. For example, turnout switch machines can be classified into two equipment types: AC switch machines and DC switch machines, where each specific AC switch machine and each specific DC switch machine has its own unique equipment ID.

[0032] Specifically, defining the sensing data model for urban rail signaling equipment involves defining, through visual configuration, sensing data items that can be obtained by monitoring or other systems for each type of equipment after categorization. This includes defining the meaning and key attributes of each sensing data item. Each sensing data item is then categorized into several sensing data types (such as switch quantities, analog quantities, and recording curves), and a fixed sensing data type ID is assigned to each type. For example, for an AC switch machine, the definable sensing data items include: position indicating switch quantity, reverse position indicating switch quantity, 1DQJ switch quantity, position indicating AC voltage analog quantity, reverse position indicating AC voltage analog quantity, position indicating DC voltage analog quantity, reverse position indicating DC voltage analog quantity, total operating power recording curve, and operating A, B, and C phase current recording curves. Among them, the position indicating a switch quantity, the reverse position indicating a switch quantity, and the 1DQJ switch quantity belong to the switch quantity sensing data type; the position indicating an AC voltage analog quantity, the reverse position indicating an AC voltage analog quantity, the position indicating a DC voltage analog quantity, and the reverse position indicating a DC voltage analog quantity belong to the analog quantity sensing data type; the total power recording curve of the action and the current recording curves of phases A, B, and C of the action belong to the recording curve sensing data type.

[0033] Specifically, the definition of the alarm data model for urban rail signaling equipment involves defining, through visual configuration, the alarm data that can be obtained by monitoring or other systems for each type of equipment after categorization. Each type of alarm data is then coded, meaning a fixed alarm code is assigned to each type of alarm data. For example, for an AC switch machine, the definable alarm data includes positioning gap alarms and reverse positioning gap alarms, each assigned a separate alarm code.

[0034] S1.2 Based on the main model, perception data model and alarm data model of urban rail signaling equipment, define the supervision rule model of various types of urban rail signaling equipment, including the definition of supervision items, the logical judgment content of each supervision item, the associated data objects and the pass criteria.

[0035] The defined supervision rule model for urban rail signaling equipment is specifically as follows: Supervision rules for each type of equipment are defined under the equipment types defined in S1.1 using a visual configuration method. Multiple supervision rules can be created for each equipment type. Supervision rule parameters include rule name, analysis period, analysis duration, end-of-life control time, and timeout control time.

[0036] Furthermore, each supervision rule can be configured with multiple supervision items. Each supervision item can specify a supervision item name, a data object for the supervision item, a supervision start time, and the text displayed when supervision passes or fails. The data object for the supervision item includes sensor data or alarm data; the supervision start time includes when supervision begins or after a specified step is completed.

[0037] Furthermore, each monitored item can be configured with its logical judgment content and pass criteria. When the data object of the monitored item is alarm data, the pass criteria for the monitored item are: select multiple alarm codes under this device type; if any alarm in the selected alarm code set is triggered, pass; if all alarms are triggered, pass; if none of the alarms are triggered, pass; if none of the alarms are triggered and then recovered, pass. When the data object of the monitored item is sensor data, the type of sensor data used can be configured, and the pass criterion logic can be edited through a Python script. The Python script can reference real-time sensor data at the time of monitoring for logical judgment.

[0038] S1.3 Define the mapping relationship between urban rail signaling equipment and target equipment in the production planning management system, so that the urban rail signaling equipment has the conditions for data exchange with the maintenance instructions of the production planning management system.

[0039] The mapping relationship between the definition and the target equipment in the production planning management system is as follows: import the target equipment list file exported from the production planning management system in a visual manner; establish a mapping table between the unique equipment ID of the urban rail signaling equipment defined in S1.1 and the unique ID of the target equipment in the production planning management system by matching equipment names; when maintenance instruction data is received, the maintenance instruction data is associated with the corresponding equipment in the main model of the urban rail signaling equipment by looking up the mapping table, so that the urban rail signaling equipment has the conditions to communicate with the maintenance instruction data of the production planning management system.

[0040] S1.4 Configure the equipment required for monitoring.

[0041] The specific devices to be monitored in the configuration are added visually under the monitoring rules defined in step S1.2, and the specific devices to which the monitoring rules apply.

[0042] S2. After the maintenance operation is triggered, the supervision process is automatically executed, including: receiving maintenance instruction data from the production planning management system in real time, parsing and mapping it into tasks to be processed; performing logical judgments and analyses on the tasks to be processed in sequence based on the predefined supervision rule model; and finally feeding back the supervision results to the production planning management system.

[0043] Step S2 specifically includes the following steps: S2.1 When maintenance work begins, maintenance instruction data from the production planning management system is received in real time. The maintenance instruction data includes at least target equipment information and the maintenance task time range for each target equipment. The maintenance task time range includes the start and end times of the maintenance task. Then, the target equipment information sent by the production planning management system is parsed and mapped to the urban rail signaling equipment master model defined in step S1.1. The parsed and mapped data is recorded as a task to be processed and added to the task queue.

[0044] S2.2. Start traversing the task queue to be processed described in step S2.1. For each task item to be processed in the queue, according to the device information recorded therein, associate it with the supervision rule model predefined for this type of device in step S1.2, that is, match the applicable supervision rule for this device.

[0045] S2.3. Based on the supervision rules determined in step S2.2, perform timed processing on the tasks to be processed, and determine whether the start time of the maintenance task associated with the task to be processed has passed. If so, create a single-device analysis task and execute the various supervision rules associated with that device. The execution process of each supervision rule is as follows: First, according to the data object specified for each supervision item in step S1.2, obtain the corresponding data from the device. Then, based on the obtained data, perform logical judgment to obtain the supervision result of whether each supervision item meets the passing criteria, and record the supervision result.

[0046] S2.4 Repeat steps S2.2 and S2.3 until the end time of the maintenance task associated with each pending task item in the pending task queue has arrived, and at the same time notify the production planning management system of the monitoring results.

[0047] S2.5 If there are any pending tasks that have not been completed within the maintenance task time frame, a progress delay warning message will be automatically generated and sent to the large screen page of the supervision and control integrated display module before the maintenance work is completed, to provide a reminder.
