Description

Technical Field

[0001] The present invention relates to the technical field of subway tunnel operation, and in particular to an automatic flushing method, equipment and storage medium for a subway tunnel. Background Art

[0002] During the continuous operation of the subway, a large amount of dust and debris will gradually accumulate in the tunnel. The piston wind brought by the running of the train will roll up the above air pollutants and diffuse throughout the tunnel, which will not only affect the comfort of the train operation, but also enter the station with the use of the tunnel fan, seriously affecting the air quality in the train and the station. Therefore, the subway operating unit will regularly clean the subway tunnel.

[0003] In the existing urban rail transit lines, whether in manned or unmanned operation lines, subway tunnel cleaning currently relies mainly on subway operators to manually drive subway tunnel washing trains and manually wash tunnels at night. Operations such as adding water to the train, driving the train and reaching the operation area, tunnel washing, exiting operations, and secondary operations all require manual operations. This manual operation method has a large workload and complex operations, a low level of automation, low operating efficiency, long time consumption, and high labor costs. Summary of the invention

[0004] The purpose of the present invention is to provide a subway tunnel automatic flushing method, equipment and storage medium in order to overcome the defects of the above-mentioned prior art.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] According to a first aspect of the present invention, there is provided a method for automatic flushing of a subway tunnel, which is implemented based on a signal autonomous operation system TACS, wherein the signal autonomous operation system TACS includes a trackside resource manager WRC, an ATS subsystem and an ATC onboard controller, wherein the ATC onboard controller is installed on a subway tunnel flushing train; the method comprises:

[0007] Step 1: The ATS subsystem obtains the tunnel flushing operation plan and sends it to the ATC onboard controller;

[0008] Step 2: The ATC onboard controller controls the flushing train to add water according to the tunnel flushing operation plan;

[0009] Step 3: The ATS subsystem sets a working area WZ for the flushing train, the working area WZ covers and is larger than the tunnel flushing range in the tunnel flushing operation plan, and the trackside resource manager WRC sets the trackside resources of the working area WZ to a prohibited state;

[0010] Step 4: When the planned start time of the tunnel flushing operation is reached, the ATS subsystem sends a task to the ATC onboard controller to enter the work area WZ. The ATC onboard controller applies to the trackside resource manager WRC for the trackside resources to enter the work area WZ. After the resource application is successful, the ATC onboard controller controls the flushing train to enter the work area WZ and arrive at the starting point of the tunnel flushing range.

[0011] Step 5: The ATC onboard controller controls the flushing train to run within the tunnel flushing range and perform tunnel flushing;

[0012] Step 6: After the flushing operation is completed, the ATC onboard controller feeds back the operation completion information to the ATS subsystem, and the trackside resource manager WRC restores the trackside resources of the work area WZ to a normal state.

[0013] Furthermore, in the step 1, the staff sets a tunnel flushing operation plan in the ATS subsystem, and the tunnel flushing operation plan includes: the water adding time of the flushing train, the planned start and end time of the flushing operation, the tunnel flushing range, the tunnel flushing method, and whether to add water a second time and continue the flushing operation after the first operation is not completed.

[0014] Furthermore, step 2 is specifically as follows: the ATC on-board controller controls the flushing train to run to the water adding point to automatically add water within the flushing train water adding time specified in the tunnel flushing operation plan. Within the specified flushing train water adding time, if the water adding is completed, the ATS subsystem is fed back that the water adding is successfully completed. If the water adding is unsuccessful or the water adding does not reach the required water level, the ATS subsystem is fed back that the water adding fails, and an alarm is sounded at the ATS subsystem workstation. The ATS subsystem cancels the operation and prompts the staff to intervene manually.

[0015] Furthermore, in step 4, before the ATC onboard controller controls the flushing train to enter the working area WZ and reach the starting point of the tunnel flushing range, it also includes:

[0016] The ATC onboard controller controls the flushing train to run to the edge of the working area WZ and feeds back the water level information of the flushing train to the ATS subsystem;

[0017] If the water level information of the flushing train meets the preset minimum water level for the flushing operation, the ATS subsystem sends the tunnel flushing working conditions to the ATC on-board controller. The ATC on-board controller controls the flushing train to enter the working area WZ and reach the starting point of the tunnel flushing range. Otherwise, the ATS subsystem issues an alarm that the train water level is too low and reminds the staff to intervene.

[0018] Furthermore, an active detection method is adopted to determine the real-time position of the flushing train, that is, the flushing train determines the real-time position of the flushing train by reading beacons located on the track or according to its own speed and distance measuring equipment.

[0019] Furthermore, the tunnel flushing method includes any one or more of top flushing, side flushing, and bottom flushing.

[0020] Furthermore, step 5 also includes:

[0021] The real-time position of the flushing train is obtained, the cross-sectional shape of the current tunnel is obtained according to the position of the flushing train, and the angle of the water outlet pipe on the flushing train is adjusted according to the cross-sectional shape of the tunnel.

[0022] Furthermore, the cross-sectional shape of the tunnel includes but is not limited to circular, horseshoe-shaped, and rectangular.

[0023] Furthermore, step 5 also includes:

[0024] During the flushing process, the ATC onboard controller feeds back the water level information of the flushing train to the ATS subsystem in real time;

[0025] When the flushing train reaches the end of the tunnel flushing range, the water level is still greater than or equal to the preset minimum water level for the flushing operation, indicating that the flushing operation has been completed;

[0026] When the flushing train reaches the end of the tunnel flushing range and the water level is lower than the preset minimum water level for the flushing operation, the subsequent operation will be carried out according to the requirements in the tunnel flushing operation plan: "whether to add water a second time and continue the flushing operation if the first operation is not completed".

[0027] Furthermore, if it is preset that no secondary water flushing is performed, the current flushing operation is completed; if it is preset that a secondary water flushing is performed, the ATC on-board controller applies to the trackside resource manager WRC for the return of the trackside resources of the vehicle depot, controls the flushing train to add water, and returns to the last flushing stop point after the water addition is completed to continue the flushing operation until the flushing operation is completed.

[0028] According to a second aspect of the present invention, there is provided an electronic device, comprising a memory and a processor, wherein the memory stores a computer program, and when the processor executes the program, the method according to the first aspect of the present invention is implemented.

[0029] According to a third aspect of the present invention, there is provided a computer-readable storage medium having a computer program stored thereon, wherein when the program is executed by a processor, the method according to the first aspect of the present invention is implemented.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) This method realizes the interface between the tunnel flushing train and flushing equipment and the signal system. Except for the preparation of plans and the intervention of staff after the alarm in special circumstances, the rest of the process does not require the participation of staff. The entire train safety protection, train operation, water addition, information feedback, tunnel flushing, etc. can be completed unmanned, reducing the workload of staff and improving the efficiency of operation and the automation level of the system.

[0032] (2) At the same time, since the outlet pipe angle of different tunnel sections can be automatically adjusted, the efficiency of tunnel flushing operations can be improved, the waste of water resources can be reduced, and the operating costs can be reduced.

[0033] (3) The trackside resource manager WRC sets the trackside resources in the work area WZ to a prohibited state, prohibiting trains other than the flushing train from applying to enter the resources in this area, thereby ensuring the safety of the flushing operation during the process.

[0040] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given. Obviously, the described embodiment is only an embodiment of a part of the present invention, not all embodiments, and the protection scope of the present invention is not limited to the following embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0041] This specification provides method operation steps such as embodiments or flowcharts, but more or fewer operation steps may be included based on conventional or non-creative labor. The order of steps listed in the embodiments is only one way of executing the order of many steps and does not represent the only execution order. When the actual system or server product is executed, it can be executed in sequence or in parallel (for example, in a parallel processor or multi-threaded processing environment) according to the method shown in the embodiments or the drawings, or the execution order of steps without timing restrictions can be adjusted.

[0042] A subway tunnel automatic flushing method, the system equipment involved in this method is as follows Figure 1 As shown. Based on the signal autonomous operation system TACS, the signal autonomous operation system TACS includes the trackside resource manager WRC, the ATS subsystem and the ATC on-board controller, etc. The ATC on-board controller is installed on the subway tunnel flushing train to realize the interface with the tunnel flushing train and the flushing equipment; in this case, the tunnel flushing train that originally did not have ATP protection and automatic driving functions can realize the automatic driving and ATP protection of the train after realizing the interface with the ATC on-board controller, and communicate with the trackside resource manager WRC and the ATS subsystem. At the same time, it can run at different speeds and adopt different tunnel flushing modes according to different working conditions and different tunnel section types.

[0043] The interface between the signal autonomous operation system TACS and the tunnel flushing train and flushing equipment is as follows: Figure 2 As shown, the dotted line represents the hard-wired interface, the solid line represents the wired network interface, and the dash-dot line represents the wireless network interface:

[0044] Specifically, Figure 6 As shown, the method includes:

[0045] 1) The staff sets up a tunnel flushing operation plan in the ATS subsystem, which includes the time for adding water to the flushing train (start time and end time, required water level), the planned start and end time of the flushing operation (this time should include the time the flushing train leaves the depot and travels within the main line), the tunnel flushing range (with kilometer marks as the start and end points), whether to add water a second time and continue the flushing operation after the first operation is not completed, and the tunnel flushing method (flushing the tunnel top, side or roadbed separately, or flushing multiple parts at the same time); the required minimum water level for the flushing train flushing operation can also be set in the ATS subsystem, etc.

[0046] 2) The tunnel flushing operation plan is sent to the ATC on-board controller via the ATS subsystem. The ATC on-board controller controls the flushing train to run to the water adding point to automatically add water within the flushing train water adding time specified in the tunnel flushing operation plan. If the water adding is completed within the specified flushing train water adding time, the ATS subsystem is fed back that the water adding is successfully completed. If the water adding is unsuccessful or the water adding does not reach the required water level, the ATS subsystem is fed back that the water adding fails, and an alarm is sounded at the ATS subsystem workstation. The ATS subsystem cancels the operation and prompts the staff to intervene manually.

[0047] 3) After the water is added, the flushing train is powered on and waits for the flushing operation to begin.

[0048] 4) Before the flushing operation starts (e.g., 20 minutes before the scheduled start time of the flushing operation), the ATS subsystem sets an independent work area WZ based on the tunnel flushing range, such as Figure 3 As shown, this area should completely cover and be larger than the tunnel flushing range. At the same time, the trackside resource manager WRC sets the trackside resources entering the working area WZ to a prohibited state, prohibiting other trains except the flushing train from applying for resources to enter this area, thereby ensuring the operational safety during the flushing operation.

[0049] 5) When the scheduled start time of the flushing operation is reached, the ATS subsystem sends a task to the ATC onboard controller to enter the work area WZ. The ATC onboard controller applies to the trackside resource manager WRC for trackside resources to enter the work area WZ. When the resources applied for by the flushing train are successfully applied for, the ATC onboard controller controls the flushing train to run to the edge of the work area WZ according to the operation task sent by the ATS subsystem and feeds back the water level information of the flushing train at this time to the ATS subsystem. Since the TACS system is no longer equipped with secondary detection equipment such as axle counters or track circuits, the position of the train is actively detected, that is, the train determines the real-time position of the train at this time by reading the passive beacon RB or radio frequency tag on the track and its own speed and distance measurement equipment, such as Figure 3 Example.

[0050] 6) If the water level is still higher than the required minimum water level for flushing operations, the ATS subsystem sends the tunnel flushing conditions to the ATC onboard controller of the flushing train. The ATC onboard controller controls the flushing train to enter the working area WZ at a speed of 10km / h-15km / h and reach the starting point of the flushing operation range. Otherwise, the ATS subsystem workstation will issue an alarm for low train water level and remind staff to intervene to determine whether to continue the flushing operation or return to the vehicle depot for water replenishment.

[0051] 7) When the train reaches the starting point of the flushing operation range, the ATC on-board controller controls the flushing train to run at 5km / h, and according to the tunnel flushing method in the tunnel flushing operation plan (flushing the tunnel top, side or roadbed separately, or flushing multiple parts at the same time), controls the flushing water pipes of the flushing equipment to perform top flushing, side flushing, bottom flushing or multiple methods of flushing at the same time.

[0052] Since subway tunnel cross-sections have different shapes, such as circular, horseshoe, rectangular, etc., if a fixed-angle tunnel flushing method is used for different tunnel shapes, some locations in some tunnels will not be flushed thoroughly, thus failing to achieve the purpose of cleaning, while some locations in some tunnels will be over-flushed, resulting in a waste of water resources. Figure 4 As shown, since most tunnel flushing equipment adopts a fan-shaped arrangement to flush the water pipes, the circular tunnel area will be effectively flushed, while the left and right upper corners of the rectangular tunnel will not be effectively flushed, and parts of the horseshoe-shaped tunnel area will face excessive flushing.

[0053] Therefore, the ATC onboard controller obtains the tunnel section type of the corresponding position in its own electronic map according to the position of the train. The ATC onboard controller then dynamically adjusts the angle of the water outlet pipe through the interface with the flushing equipment to ensure that all positions in the tunnel are effectively flushed and the water source is fully utilized. (Note: Since different tunnel flushing trains are equipped with different flushing systems and water outlet pipe arrangements, the specific angle adjustment method needs to be configured in software based on the specific vehicle model and different tunnel sections)

[0054] 8) During the flushing process, the ATC on-board controller obtains water level information in real time.

[0055] When the train reaches the end of the tunnel flushing range and the water level is still greater than or equal to the minimum water level allowed for the flushing operation, it indicates that the flushing operation has been completed. Then the ATC onboard controller applies to the trackside resource manager WRC to return to the depot, and returns to the depot to stop, ending the flushing operation.

[0056] like Figure 5As shown, when the train reaches the end of the tunnel flushing range, the water level is lower than the minimum water level allowed for the flushing operation. The subsequent operation is performed according to the requirement in the flushing plan: "Whether to add water a second time and continue the flushing operation after the first operation is not completed". If the preset is not to add water for a second time to flush, the ATC on-board controller applies to the trackside resource manager WRC for the trackside resources to return to the depot, and returns to the depot to stop, ending the flushing operation; if the preset is to add water for a second time to flush, the ATC on-board controller applies to the trackside resource manager WRC for the trackside resources to return to the depot, and returns to the depot to add water, and returns to the mainline tunnel after the water addition is completed, and continues the flushing operation at the end point of the previous operation until the flushing operation is completed, and then applies to the trackside resource manager WRC for the trackside resources to return to the depot, and returns to the corresponding parking track of the depot to stop steadily.

[0057] 9) After the flushing operation is completed, the ATC onboard controller will feedback to the ATS subsystem that the operation has been completed. The ATS subsystem will release the set working area WZ, and the trackside resource manager will release the prohibited trackside resources and return to normal state.

[0058] The method realizes the interface between the tunnel flushing train and flushing equipment and the signal system. Except for the intervention of staff in the preparation of plans and after the alarm in special circumstances, the rest of the process does not require the participation of staff. The entire train safety protection, train operation, water addition, information feedback, tunnel flushing, etc. can be completed unmanned, reducing the workload of staff, improving the efficiency of operation and the automation level of the system. At the same time, since the angle of the water outlet pipe of different tunnel sections can be automatically adjusted, the efficiency of tunnel flushing operations can also be improved, the waste of water resources can be reduced, and the operating cost can be reduced.
