The rail transit operation and maintenance method provided by the embodiments of the present disclosure first collects data from the rail transit operation subsystem and equipment covered by the operating line through the data collection layer, and then classifies and stores the collected data through the data storage layer, and finally passes the data collection layer. The functional module layer and the business application layer perform visual output and generate operation and maintenance decisions based on the collected data, so as to facilitate the operation and maintenance personnel to view and grasp the true state of the system, reduce planned maintenance, and achieve precise operation and maintenance. As shown in Figure 2, the rail transit operation and maintenance method includes:

In step S201, the operating status information and/or system configuration information of each rail transit operation subsystem is acquired.

Here, the embodiment of the present disclosure obtains the operating status information and system configuration information of each rail transit operation subsystem covered by the operating line through the data collection layer, and each rail transit operation subsystem may include multiple devices.

Wherein, the operating status information may include status data automatically reported by the rail transit operation subsystem during operation, and/or status data reported by installing additional sensors, and this information reflects the real-time status of the operating line. The status data reported by the sensor is related to the business of the rail transit operation subsystem, including but not limited to current, voltage, temperature, humidity, speed, pressure, acceleration.

The system configuration information refers to the configuration information of the rail transit operation subsystem and its equipment, including but not limited to temporary task information, maintenance plan information, inspection feedback information, equipment parameters, and equipment principle models. Temporary task information refers to temporary and emergency maintenance tasks manually created by operation and maintenance personnel due to special reasons. The special reasons include, but are not limited to, unexpected conditions, special test requirements, and manual decisions. The maintenance plan information refers to the maintenance guidance and method suggestions given by the original equipment manufacturer. Inspection feedback information refers to the feedback result of manual inspection, which is used to supplement the operation status information reported by the rail transit operation subsystem. Through manual inspection, it is possible to feed back the true status information of the rail transit operation subsystem and its equipment itself that cannot be automatically reported and the sensor equipment is not installed. Equipment parameters refer to equipment characteristic parameters provided by original equipment manufacturers for specific equipment, reflecting the upper and lower limits of the equipment. The equipment principle model is a principle model of equipment operation provided by original equipment manufacturers. Based on this model, it is possible to gain in-depth understanding of equipment operation principles and obtain key influence parameters.

As an example of the present disclosure, the rail transit operation subsystem includes but is not limited to an automatic fare collection system, a passenger information system, and a signal system. The intelligent maintenance system and the rail transit operation subsystem can communicate with each other by means of, for example, a preset gateway, system interface, and/or message transfer, so that the intelligent maintenance system is interconnected with each rail transit operation subsystem Intercommunication, real-time collection of data fed back from the rail transit operation subsystem, and obtaining rail transit operating status information, effectively solving the problem of data islands and ensuring the timeliness of operating status information.

As mentioned earlier, each rail transit operation subsystem includes multiple devices, and the collected operating status information is large and complex. As an example of the present disclosure, in order to improve the management efficiency of the operating status information, the embodiments of the present disclosure classify and store the operating status information. Each rail transit operation subsystem sets corresponding system ID information, and each rail transit operation subsystem covers equipment sets corresponding device ID information. When the rail transit operation subsystem reports the operation status information to the intelligent maintenance system, the operation status information, system ID information, and equipment ID information are packaged and sent. The intelligent maintenance system classifies and stores the operation status information according to the received system ID information and device ID information.

As shown in FIG. 3, it is a flowchart of classified storage provided by an embodiment of the present disclosure. After the step S201 obtains the operating status information and/or system configuration information of each rail transit operation subsystem, it further includes:

In step S301, the system ID information and device ID information corresponding to the operating state information are acquired.

Wherein, the system ID information is an identifier of the rail transit operation subsystem that reports the operation status information, and is used to distinguish different rail transit operation subsystems. The device ID information is the identifier of the device that specifically reports the operating status information under the rail transit operation subsystem, and is used to distinguish different devices under the same rail transit operation subsystem.

When each rail transit operation subsystem reports the operating status information, the operating status information, system ID information, and device ID information can be packaged into status data packets for transmission. When the intelligent maintenance system collects status data packets from various rail transit operation subsystems through preset gateways, calling system interfaces, etc., it further analyzes the status data packets to obtain real-time operating status information and its corresponding System ID information and device ID information of the device.

In step S302, the operating state information is stored in a storage sub-area in the database, where the storage sub-area is determined by the system ID information and device ID information.

The embodiment of the present disclosure divides the database according to each rail transit operation subsystem and the equipment below it in advance. Each rail transit operation subsystem corresponds to a storage area in the database. The storage area is based on the system ID corresponding to the rail transit operation subsystem. Information naming; the storage area corresponding to the rail transit operation subsystem is divided into multiple storage sub-areas according to the devices under the rail transit operation subsystem, and the storage sub-areas are named after the device ID information of the device. For example, the storage area corresponding to the signal system is named 123456 and the system ID information corresponding to the signal system is 123456. The signal system includes speed sensors, direction sensors and other devices. The storage sub-area corresponding to the speed sensor is named device ID information sd, The storage sub-area corresponding to the direction sensor is named device ID information fx. After obtaining the operating status information and its corresponding system ID information and device ID information, the corresponding storage area is found according to the system ID information, and then the corresponding storage sub-area is found according to the device ID information, and the operation The status information is stored in the storage sub-area, thereby completing the classified storage of the operating status information, which is beneficial to the unified management of the operating status information of each rail transit operation subsystem.

As an example of the present disclosure, on the basis of the classified storage shown in FIG. 3, as shown in FIG. 4, a flowchart for implementing the visualization processing provided by the embodiment of the present disclosure is shown. After the step S201 obtains the operating status information and/or system configuration information of each rail transit operation subsystem, it further includes:

In step S401, the system ID information and the device ID information are acquired according to the query instruction, and the operating status information corresponding to the system ID information and the device ID information is acquired from the database.

Specifically, operation and maintenance personnel can view specific aspects of the status information on rail transit, such as the operating speed of trains, by entering query instructions, for example. The intelligent maintenance system retrieves system ID information and device ID information according to the query instruction, and then queries the database according to the system ID information and device ID information to obtain corresponding operating status information. Taking the running speed of the aforementioned train as an example, the intelligent maintenance system queries the storage area corresponding to the information system according to the system ID information 123456, and then queries the storage sub-area in the storage area according to the device ID information sd, and reads the storage From the data in the sub-area, get the running speed of the train.

In step S402, visual processing is performed on the operating state information, and the visualized operating state information is displayed.

The embodiments of the present disclosure use computer graphics and image processing technology to convert the operating status information into graphics or images and display them on the screen to achieve real-time monitoring, which greatly facilitates the operation and maintenance personnel to view and grasp the truth of the operating line status.

In step S202, the operation status information and/or system configuration information is analyzed to generate an operation and maintenance decision plan of the rail transit operation subsystem.

Here, the operation status information reflects the current real operation information of each rail transit operation subsystem. It is the first-hand data to grasp the operation status of rail transit. It is objective and true. It has a high level of operational and maintenance decisions based on the operation status information. Scientific rigor improves the feasibility of decision-making, avoids subjective misjudgment by operators, and reduces the cost and waste caused by excessive maintenance.

The embodiments of the present disclosure analyze the operating status information and/or system configuration information, including analysis of real-time status, analysis of health assessment information, analysis of failure prediction information, analysis of temporary maintenance information, and maintenance plan There are six aspects of information analysis and inspection result information analysis. The analysis of each aspect may generate at least one of maintenance work orders, maintenance work orders, and inspection work orders. Among them, the maintenance work order refers to the work document that needs to be repaired when the equipment fails, the maintenance work order refers to the work document that needs maintenance for the equipment to perform poorly, and the inspection work order refers to the work document that the equipment needs to be inspected.

As an example of the present disclosure, the specific implementation process of real-time status analysis decision-making is given below. As shown in FIG. 5, the step S202 includes:

In step S501, real-time status analysis is performed on the operating status information.

Here, real-time status analysis refers to data analysis performed with only running status information as the analysis object. The embodiments of the present disclosure perform real-time status analysis on the running status data reported at each moment, including judging fault information, calculating reporting frequency, and monitoring fluctuations. Rules to analyze and locate possible problems and corresponding problem equipment.

In step S502, if the operating status information includes fault status information, a maintenance work order corresponding to the problem equipment is generated.

In step S503, if the running status value reported multiple times within the specified time range of the same information item in the running status information is close to the upper threshold or the lower threshold, a maintenance work order corresponding to the problem equipment is generated, where the close to the upper threshold is Means that the difference between the reported running state value and the upper threshold is less than or equal to the approach threshold. Near the lower threshold means that the difference between the reported running state value and the lower threshold is less than or equal to the approach threshold.

Among them, each information item corresponds to a pair of upper threshold and lower threshold. For example, when the operating status information includes N information items, there can be N pairs of upper threshold and lower threshold. The upper threshold and lower threshold are used to determine whether the corresponding information item There is a problem.

In step S504, if the operating status information exhibits irregular fluctuations, a patrol work order corresponding to the problem device is generated.

Among them, the content contained in the operating status information intuitively reflects the status of the rail transit operation subsystem and equipment. If the operating status information includes fault status information, it indicates that the equipment corresponding to the fault status information has failed, and a maintenance work order corresponding to the faulty equipment is generated.

The running status value of some information items in the running status information has a corresponding floating range. When the running status value exceeds a preset upper threshold or lower threshold, a dangerous situation will occur; when the running status When the value is close to the upper threshold or lower threshold for many times, it indicates that the device is currently prone to dangerous situations. The embodiments of the present disclosure screen out potentially dangerous equipment by monitoring whether the running state value reported multiple times by the same information item is close to the upper threshold or the lower threshold. Specifically, by setting the approach threshold, the difference between the operating state value reported by the same information item at different times and the upper threshold or lower threshold is calculated, and if the difference is less than or equal to the approach threshold multiple times, then It is considered that the running status value of the information item reported multiple times within the specified time range is close to the upper threshold or the lower threshold, and a maintenance work order corresponding to the problem equipment is generated.

Similarly, the fluctuation rule of the operating status information is also stable or fluctuates within a specified range. If the operating status information at a certain moment fluctuates irregularly, it indicates that the equipment in the rail transit operation subsystem will have operational problems, and the equipment in the rail transit operation subsystem needs to be inspected. In the embodiments of the present disclosure, by monitoring the fluctuation rules of the operating status information, the problem devices exhibiting irregular fluctuations are screened, and the inspection work order corresponding to the problem device is generated.

As an example, the real-time status analysis may further include:

If the reporting frequency of the operating status information is less than the lower frequency threshold or greater than the upper frequency threshold, a maintenance work order corresponding to the problem equipment is generated.

Here, the reporting frequency is the difference between the current reporting time of the running status data and the previous reporting time. Generally, the reporting frequency of the operating status information of the rail transit operating subsystem and its equipment is stable or fluctuates within a specified range. If the reporting frequency of the operating status information is too slow or too fast, it indicates that the equipment in the rail transit operation subsystem is about to fail, and timely maintenance of the equipment in the rail transit operation subsystem is required. Therefore, the embodiments of the present disclosure filter out potentially problematic devices by setting a lower limit frequency threshold and an upper limit frequency threshold. When the reporting frequency of the operating status information is less than the lower frequency threshold or greater than the upper frequency threshold, a maintenance work order corresponding to the problem equipment is generated.

The above real-time status analysis of the operating status data realizes the status repair of the equipment in the rail transit operation subsystem, effectively avoids planned repairs, and helps reduce operation and maintenance costs.

As an example of the present disclosure, the specific implementation process of the health assessment analysis decision is given below. As shown in FIG. 6, the step S202 includes:

In step S601, the health status assessment is performed on the current operating state information and system configuration information to obtain the health value corresponding to the equipment in the rail transit operation subsystem.

Here, the system configuration information includes equipment parameters and equipment principle models. Health assessment analysis refers to the evaluation of the health value of the equipment in the rail transit operation subsystem based on the degradation model, combined with historical data, equipment parameters, equipment principle models and current operating status information, to obtain a health value about the equipment.

In step S602, if the health value is less than the first expected health threshold, a maintenance work order for the equipment corresponding to the health value is generated, and if the health value is greater than the first expected health threshold and less than the second expected health threshold, then Generate an inspection work order for the equipment corresponding to the health value.

The health value reflects the operating state of the equipment in the rail transit operation subsystem. When the health value is high, the operating state of the equipment is good, and when the health value is low, the operating state of the equipment is poor. The embodiment of the present disclosure sets a first expected health threshold and a second expected health threshold, where the first expected health threshold is smaller than the shown second expected health threshold. The first expected health threshold is used to determine whether the equipment is about to fail, and is a criterion for determining whether a maintenance work order is generated. The second expected health threshold is used to determine whether the equipment has operating problems, and is a criterion for determining whether to generate an inspection work order. The health value is compared with the first expected health threshold and the second expected health threshold, and if the health value is less than the first expected health threshold, a maintenance work order is generated, and if the health value is greater than the first expected health threshold If the health threshold is less than the second expected health threshold, an inspection work order is generated.

As an example of the present disclosure, the specific implementation process of the failure prediction analysis decision is given below. As shown in FIG. 7, the step S202 includes:

In step S701, the prediction model is used to perform fault prediction on the current running state information and system configuration information, and the failure probability corresponding to the equipment in the rail transit operation subsystem within the preset time range from the current moment is obtained.

Here, the system configuration information includes equipment parameters and equipment principle models. Failure prediction analysis refers to the use of predictive model algorithms, combined with historical failure data, equipment parameters, equipment principle models, and current operating status information to predict the probability of equipment failure in the rail transit operation subsystem, and obtain the rail transit operation subsystem The probability that the device will fail within the next preset time frame. The prediction model algorithm includes, but is not limited to, logistic regression algorithm, arima algorithm based on time series, and recurrent neural network algorithm.

In step S702, if the failure probability is greater than or equal to the failure probability threshold, a maintenance work order for the equipment corresponding to the failure probability is generated.

The failure probability reflects the probability of failure of the equipment in the rail transit operation subsystem. When the failure probability is high, the equipment in the rail transit operation subsystem is prone to failure. When the failure probability is low, the rail transit operation subsystem The equipment in is not prone to failure. The embodiment of the present disclosure sets a failure probability threshold, which is used to determine whether the equipment in the rail transit operation subsystem is about to fail, as a criterion for determining whether to generate a maintenance work order. The failure probability is compared with the failure probability threshold, and if the failure probability is greater than or equal to the failure probability threshold, a maintenance work order for the equipment corresponding to the failure probability is generated.

As an example of the present disclosure, the system configuration information may also include temporary maintenance information, and the temporary maintenance information refers to a maintenance task of a specified device manually created by an operation and maintenance personnel. When performing temporary maintenance analysis and decision-making, the intelligent maintenance system generates maintenance work orders based on maintenance tasks created by operation and maintenance personnel. The step S202 further includes: generating a maintenance work order according to the temporary maintenance information in the system configuration information.

As an example of the present disclosure, the system configuration information may also include maintenance plan information, and the maintenance plan information refers to the maintenance tasks of the specified equipment in the preset maintenance plan content. When performing maintenance plan analysis and decision-making, the intelligent maintenance system generates a maintenance work order according to the maintenance plan. The step S202 further includes: generating a maintenance work order according to the maintenance plan information in the system configuration information.

As an example of the present disclosure, the system configuration information may also include inspection feedback information. The patrol inspection feedback information refers to the feedback result of manual patrol inspection, including the actual status information of the equipment in the rail transit operation subsystem that cannot automatically report and the equipment without additional sensors. When performing inspection feedback analysis and decision-making, after the inspection feedback information is submitted to the intelligent maintenance system, the intelligent maintenance system combines the equipment model to generate a corresponding maintenance work order or maintenance work order. The step S202 further includes:

A maintenance work order and/or maintenance work order is generated according to the inspection feedback information, equipment parameters, and equipment principle model in the system configuration information.

As mentioned earlier, equipment parameters refer to equipment characteristic parameters provided by original equipment manufacturers for specific equipment, reflecting the upper and lower limits of equipment. The equipment principle model is a principle model of equipment operation provided by original equipment manufacturers. Based on this model, it is possible to gain in-depth understanding of equipment operation principles and obtain key influence parameters. The embodiments of the present disclosure obtain key influencing parameters according to the inspection feedback information and equipment principle model in the system configuration information, and then compare the key influencing parameters with the equipment parameters, and screen out the problematic equipment according to the comparison results , Generate repair work orders and/or maintenance work orders for problem equipment.

In summary, the embodiments of the present disclosure make operation and maintenance decisions based on operating status information and system configuration information, which has high scientific rigor, improves the feasibility of decision-making, and effectively reduces the dependence on traditional planned maintenance. It also reduces the cost and waste caused by excessive maintenance.

In step S203, the operation and maintenance decision plan is distributed to instruct the operation and maintenance personnel who received the operation and maintenance decision plan to perform repair, maintenance or inspection.

The above-mentioned operation and maintenance decision-making plan generated through real-time status analysis, health assessment analysis, failure prediction analysis, temporary maintenance analysis, maintenance plan analysis, and inspection result analysis will be sent to the corresponding operation and maintenance personnel, and the operation and maintenance personnel will be based on the operation and maintenance The maintenance decision plan implements repair, maintenance or inspection work.
