Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, in particular to a system and method for monitoring the progress of EMU operation and maintenance in an EMU depot. BACKGROUND

[0002] In the high-speed railway operation system, the EMU depot and the EMU station are the key nodes for the operation and maintenance of EMU, which directly affect the operation safety and efficiency of EMU. The operation of the EMU depot and the EMU station is characterized by frequent arrival, departure and shunting operations, and the maintenance operation is mainly concentrated in the night and early morning. Among them, the arrival, departure and shunting operations of EMU in the EMU depot and the EMU station are operation operations. Whether the EMU can arrive at the storage yard on time and be adjusted into the maintenance yard on time is of great importance to the progress of the EMU maintenance operation. At the same time, whether the maintenance operation can be completed on time is an important factor for the EMU to operate on time. At present, the operation and maintenance of EMU in the EMU depot and the EMU station are controlled by different operation personnel, and the operation personnel cannot real-time grasp the operation progress of other departments. With the continuous increase in the number of EMU in operation, higher requirements are put forward for the punctuality and efficiency of the operation and maintenance of EMU in the EMU depot and the EMU station.

[0003] The EMU depot and the EMU station are generally equipped with a centralized control system (CCS system) of the EMU depot and the EMU station, which is used by the station personnel of the field train department. The CCS system has functions such as operation plan management, dispatching command management, EMU position tracking and operation process control. According to the post setting of the EMU depot and the EMU station, the CCS system is equipped with a signalman terminal and a duty officer terminal. The signalman terminal is used to display the station equipment state and track the EMU position in the whole field. The duty officer terminal displays the execution of the arrival, departure and shunting operation plan of the EMU, automatically collects the progress of the operation plan execution, and ensures the smooth operation of the arrival, departure and shunting operation.

[0004] The maintenance yard of the EMU depot and the EMU station is equipped with a maintenance operation registration and cancellation system, which is used by the maintenance personnel of the field maintenance yard. The system provides functions such as clock-in input by the maintenance personnel and real-time display of the maintenance operation on the same day.

[0005] At present, there are mainly two kinds of schemes for monitoring the progress of EMU operation and maintenance in the EMU depot and the EMU station:

[0006] Scheme one: using the CCS system to monitor the progress of EMU operation in the EMU depot and the EMU station.

[0007] The arrival, departure and shunting operation progress of the motor train unit in the motor train depot and the motor train station is monitored by the station staff of the train service department through the CCS system. The CCS system obtains the motor train unit arrival, departure and shunting operation plan information, and determines whether the relevant operation plan is completed according to the real-time position of the motor train unit.

[0008] However, the defects are:

[0009] (1) Only the operation progress of the motor train unit in the motor train depot and the motor train station is monitored, and the monitoring of the repair operation progress of the motor train unit is lacking. When the repair operation of the motor train unit is overtime, the station staff of the on-site train service department cannot obtain the overtime information in time.

[0010] (2) The CCS system is set in the local area network and adopts the C / S (server / client) architecture, and the operation personnel of other departments cannot directly view the operation progress information of the motor train unit in the motor train depot and the motor train station.

[0011] (3) When the motor train unit arrival, departure and shunting operation are delayed, the CCS system cannot provide alarm prompts to the operation personnel.

[0012] Scheme two: using the repair operation registration and cancellation system to monitor the repair operation progress of the motor train unit in the motor train depot and the motor train station.

[0013] The on-site dispatchers of the vehicle department monitor the repair operation production progress of the motor train unit by checking the repair operation registration and cancellation system, and cooperate with the use of handheld radios, camera remote control and other methods. The on-site dispatchers manually register and report the relevant operation time of the motor train unit.

[0014] However, the defects are:

[0015] (1) Only the repair operation progress of the motor train unit in the motor train depot and the motor train station is monitored, and the monitoring of the operation progress of the motor train unit is lacking. When the operation of the motor train unit is overtime, the dispatchers of the on-site vehicle department cannot obtain the delay information in time.

[0016] (2) The dispatchers of the on-site vehicle department still need to manually register and report the operation and repair time.

[0017] (3) The dispatchers of the on-site vehicle department need to manually judge the overtime delay of the repair operation.

[0018] And, the CCS system and the maintenance operation registration and deregistration system involved in the above two schemes are respectively provided for operation personnel of different departments, are independent of each other, and are not integrally managed between each other, so that the two systems lack interface interaction; and, since the two systems respectively adopt different local area networks, the CCS system involves signal control data, the maintenance operation registration and deregistration system involves maintenance operation data, and the CCS system data involves a higher safety level than the maintenance operation registration and deregistration system, therefore, the two systems cannot directly interface and interact.

[0019] In addition, the Chinese invention patent application with the publication number CN114077902A, a high-efficiency EMU intelligent maintenance system and control method, discloses a scheme to realize efficient EMU intelligent maintenance, but it cannot monitor the operation and maintenance operation progress of the EMU in the EMU depot and EMU station. The Chinese invention patent application with the publication number CN105678357A, an EMU maintenance operation process management and control system and method, discloses a scheme in which a handheld terminal, an RFID reader, an RFID electronic tag, and a server device are used to match the RFID electronic tag information of the current position of the maintenance personnel with the electronic tag data in the database, and when the matching is successful, the completion progress of the current maintenance operation task is determined according to the position information of the RFID electronic tag, to realize the management and control of the EMU maintenance operation process. Although this scheme can detect the EMU maintenance operation progress, it determines the progress according to the current position of the maintenance personnel, which lacks accuracy in judging the maintenance operation progress and lacks accuracy in recording the specific maintenance operation time. At the same time, this scheme only controls the EMU maintenance operation progress, and does not monitor the operation progress of the EMU in the EMU depot and EMU station. SUMMARY

[0079] In order to more clearly show the technical solutions provided by the present application and the technical effects produced, the system provided by the embodiments of the present application is described in detail below with specific examples.

[0080] I. System architecture design

[0081] The EMU section / EMU depot operation and maintenance operation progress monitoring system provided by the embodiments of the present application adopts a B / S (browser / server) architecture, and mainly comprises: a monitoring terminal, an interface server, a website server, a database server, a printer, and a network isolation device, as shown in Figure 2 .

The interface server is used to receive EMU operation data from a CCS system and EMU maintenance operation data from a maintenance operation registration and deregistration system, and transmit the above operation data to the database server. The website server is used to complete logical calculation of related EMU operation and maintenance operation data, late departure alarm, and the like. The database server is used to store various types of operation data.

[0082] As shown in Figure 3 , the main working process of the system is shown.

The website server reads the related data stored in the database server, performs data integration and logical calculation, performs late departure time calculation by combining actual data of related operations, and finally displays the calculation results by the front end.

[0083] II. EMU operation and maintenance operation progress monitoring scheme

[0084] 1. Operation flow of EMU in EMU section or EMU depot

[0085] The operation flow of the EMU in the EMU section or EMU depot is shown in Figure 4 . The EMU departs from a neighboring station, enters a storage yard of the EMU section or EMU depot, and according to subsequent specific arrangements, there are two cases for the EMU operation, one is to be adjusted from the storage yard to a maintenance library for direct maintenance operation, and the other is to be adjusted from the storage yard to other tracks for temporary parking, and then to enter the maintenance library for maintenance according to the subsequent plan. After the EMU enters the maintenance library and completes the maintenance operation, it will be adjusted to the storage yard or other tracks (corresponding to post-out operation) according to subsequent arrangements, and finally the EMU will depart from the storage yard and enter the neighboring station. According to the operation flow of the EMU in Figure 4 , the monitoring of the operation progress of the EMU in the EMU section or EMU depot can be divided into: arrival operation, pre-entry operation, maintenance operation, post-out operation, and departure operation, each part has a corresponding operation progress module to record the operation progress, forming the operation and maintenance operation progress table shown in Table 1.

[0086] Table 1: EMU section and EMU depot operation and repair work schedule

[0087]

[0088] 2. Operation data processing.

[0089] (1) EMU operation data and repair work data.

[0090] (1.1) The operation data mainly includes: train set number, starting track, destination track, operation time. It includes three types of train data, departure data and shunting data (used to control the pre-storing operation and post-storing operation, and provide the arrival time filling in the repair work progress module).

[0091] Exemplary:

[0092] (a) Train data: train set number A1, 6G, 2G, 16:00; wherein train set number A1 refers to the EMU train set number, 6G is the departure track of the adjacent station, 2G is the arrival track of the EMU section or depot, and 16:00 indicates that the EMU train set with train set number A1 arrives at the EMU section or depot 2G at 16:00.

[0093] (b) Departure data: train set number A2, 5G, 10G, 7:00; wherein train set number A2 refers to the EMU train set number, 10G is the arrival track of the adjacent station, 5G is the departure track of the EMU section or depot, and 7:00 indicates that the EMU train set with train set number A2 departs from the EMU section or depot 5G at 7:00.

[0094] (c) Shunting data: train set number A3, 7G, inspection 5, 18:00; wherein train set number A3 refers to the EMU train set number, 7G and inspection 5 are both tracks of the EMU section or depot, and 18:00 indicates that the EMU train set with train set number A3 arrives at inspection 5 at 18:00.

[0095] (1.2) Repair work data mainly includes: train set number, repair track, repair work start time, repair work end time.

[0096] Exemplary repair data: train set number A4, inspection 6, 18:00, 20:00; indicating that the repair work of the EMU train set with train set number A3 at inspection 6 starts at 18:00 and ends at 20:00.

[0097] (2) Operation information data preprocessing and grouping.

[0098] Because the same EMU train set may perform multiple shunting operations in the EMU section or depot, and the shunting operation information does not have sequential nature, the received operation information data of the EMU train set needs to be sorted and integrated.

[0099] (2.1) In order to avoid confusion of different train set data, and the train set number is unique, therefore, grouping is carried out according to the train set number, and the data of the same train set is ensured to be processed collectively.

[0100] (2.2) Separation of data types: the operation information data of the same train set is separated according to the arrival, departure and shunting.

[0101] Since the starting track or the destination track of the arrival and departure data is the data of the adjacent station, the classification can be carried out according to this principle. Specifically, the operation information data preprocessing and grouping process is as shown in Figure 5 Firstly, grouping is carried out according to the train set number, and then, each group is traversed, and the data is separated according to whether the starting track and the destination track of each data in the group are adjacent station tracks.

[0102] (3) Construction of shunting mapping table.

[0103] In the embodiment of the present application, according to the operation process of the train set, a dictionary structure is constructed to store the track operation data, the key is the shunting starting track, and the value is the corresponding destination track and operation time, so as to ensure that the chain relationship can be quickly found subsequently.

[0104] In order to facilitate understanding, the following examples are introduced in combination with Table 2.

[0105] Table 2: Shunting data example of train set A4 of the train set in the operation information data after carding

[0106]

[0107] Based on the shunting data shown in Table 2, the shunting mapping table of the train set A4 of the train set is constructed = {“3 track”: (“4 track”, “08:15”), “5 track”: (“check 10”, “09:00”), “4 track”: (“5 track”, “08:30”), “check 10”: (“11 track”, “11:30”)}.

[0108] (4) Construction of shunting track operation sequence table.

[0109] In the embodiment of the present application, the destination track of the train set arrival data is taken as the current track, and the shunting mapping table is searched circularly until the current track does not exist in the shunting mapping table, and the construction method of the shunting track operation sequence table is as shown in Figure 6 .

[0110] In order to facilitate understanding, the following examples are provided.

[0111] In this example, the arrival data of the train set A4 has a destination track of 3, and the operation time is 08:00. The departure data of the train set A4 has a starting track of 11, and the operation time is 12:00. The shunting mapping table of the train set A4 is {“3 track”: (“4 track”, “08:15”), “5 track”: (“check 10”, “09:00”), “4 track”: (“5 track”, “08:30”), “check 10”: (“11 track”, “11:30”)}.

[0112] Set 3 as the current track and search for the next shunting destination track (i.e. the corresponding destination track when the current track is used as the starting track) as 4, and the operation time is 08:15. Set 4 as the current track, and record 4 and the operation time 08:15 in the track operation sequence list.

[0113] Search with 4 as the key and get the next shunting destination track as 5, and the operation time is 08:30. Set 5 as the current track, and record 5 and the operation time 08:30 in the track operation sequence list.

[0114] Search with 5 as the key and get the next shunting destination track as check 10, and the operation time is 09:00. Set check 10 as the current track, and record check 10 and the operation time 09:00 in the track operation sequence list.

[0115] Search with check 10 as the key and get the next shunting destination track as 11, and the operation time is 11:30. Set 11 as the current track, and record 11 and the operation time 11:30 in the track operation sequence list.

[0116] When searching with 11 as the key, the shunting mapping table cannot search for corresponding data. The current track is the departure starting track 11, indicating that the shunting search process is over.

[0117] The final sorted track sequence is: 3 → 4 → 5 → check 10 → 11, and the operation time of each track is recorded.

[0118] 3. Fill in the operation and maintenance progress table.

[0119] Based on the data processed by the above operation data, fill in the operation and maintenance progress table.

[0120] (1) Fill the starting track, destination track and operation time contained in the arrival data and departure data in the operation information into the arrival operation progress module and departure operation progress module; wherein, the arrival time and departure time in the arrival operation progress module and departure operation progress module are the operation time corresponding to the arrival data and departure data.

[0121] (2) Since the train set number of the motor train set is unique, when filling in the repair operation module, the train set number in the operation and repair operation schedule table needs to be matched, and considering the case of multiple entries of the motor train set into the warehouse, the repair track in the repair operation information and the operation track in the operation sequence list need to be matched, and after successful matching, it is judged whether the repair operation start time is later than the entry time, and after meeting the conditions, the repair track and repair operation time in the repair operation information are filled into the repair operation progress module. At the same time, the operation time of the repair track in the operation sequence list can be filled into the arrival time in the repair operation progress module. Figure 7 The filling process of the repair operation progress is shown.

[0122] (3) When filling in the pre-entry operation progress module and post-exit operation progress module, for each motor train set, the corresponding operation sequence list of the shunting track needs to be split; specifically, taking the repair track as the splitting basis, the data before the repair track is filled into the pre-entry operation progress module, and the data after the repair track is filled into the post-exit operation progress module; similarly, the arrival time in the pre-entry operation progress module and post-exit operation progress module is the operation time of the corresponding track in the operation sequence list of the shunting track.

[0123] III. Motor train set operation and repair operation delay and overtime alarm

[0124] The data sent by the CCS system and the repair operation registration and deregistration system contains both planned and actual data. When monitoring the operation and repair operation progress of the motor train set, the planned operation and repair operation schedule table and the actual operation and repair operation schedule table of the motor train set are constructed according to the scheme introduced in the second part. At the same time, considering the demand for alarm tolerance of on-site operation personnel, the alarm threshold is set, and the arrival delay, departure delay, pre-entry delay, post-exit delay and repair operation time are calculated.

[0125] 1. Delay alarm

[0126] The same logic is used for arrival delay, departure delay, pre-entry delay, post-exit delay.

[0127] If the difference between the actual operation time and the planned operation time is greater than the first alarm threshold, a late alarm is generated; if the difference is less than the alarm threshold, no late alarm is generated. The actual operation time and the planned operation time here are the operation times recorded in the operation progress module corresponding to the same operation type in the actual operation and maintenance progress table and the planned operation and maintenance progress table; the operation times corresponding to different operation types are different in category, for example, for the car receiving operation, the operation time is the arrival time, and for the car dispatching operation, the operation time is the departure time; taking the example of judging whether the car receiving is late, the difference is calculated using the arrival time recorded in the car receiving operation progress module in the actual operation and maintenance progress table and the planned operation and maintenance progress table, and compared with the alarm threshold to determine whether a late alarm is generated.

[0128] For example, the planned car receiving time of the motor train unit of A5 is 18:00, the actual time is 18:10, the alarm threshold is 5 minutes, according to the calculation, the actual late time is 10 minutes, which is greater than the alarm threshold of 5 minutes, indicating that the car receiving is late, and the system prompts the car receiving late alarm prompt.

[0129] 2. Maintenance timeout alarm.

[0130] Insufficient maintenance operation time calculation logic: Since whether the maintenance operation is completed directly affects whether the motor train unit can depart on time, whether the maintenance operation time is sufficient depends on the departure plan time combined with the alarm threshold to calculate whether the shunting into the maintenance depot is reasonable, so as to determine whether to generate a maintenance timeout alarm.

[0131] For example, the planned departure time of the motor train unit of A5 is 18:00, the actual shunting into the depot time is 17:40 (i.e. the arrival time recorded in the maintenance operation progress module in the actual operation and maintenance progress table), and the insufficient maintenance operation time alarm threshold (the second alarm threshold) is 30 minutes. According to the calculation, the motor train unit of A5 should be shunted into the depot at the latest at 17:30, but the actual shunting into the depot time is 17:40, at which time the maintenance operation cannot be completed on time, so the system needs to generate a maintenance timeout alarm prompt.

[0132] It should be noted that the above train group numbers A1-A5 are only simple train group number examples provided for convenience of representation, and in actual application, numbering needs to be performed according to specifications.
