Description

Technical Field

[0001] This invention relates to the field of track data processing technology, and in particular to a method, system, device, equipment, medium and product for measuring the locking amount of an externally locking turnout. Background Technology

[0002] Turnouts are an important component of rail transit lines. Trains change from one track to another, that is, the change of travel direction is achieved through turnout switching. Generally, turnout tracks consist of movable rails and fixed rails. When switching, the movable rails move from one side to the other, realizing the change of the track for the turnout.

[0003] External locking devices are crucial equipment for locking movable rails. For externally locked turnouts, the locking amount refers to the travel distance of the external locking device from the start to the end of locking. According to the standard "Q / CR848-2021 Technical Conditions for Installation of Railway Turnout Switching Equipment," the locking amount of the external locking device should be no less than 25mm at the first traction point of the switch rail and frog rail, and no less than 20mm at other traction points; the limit deviation of the difference in locking amount between the two sides of the external locking device is 2mm. Therefore, locking amount is a critical aspect of turnout maintenance and repair in the rail transit field. Currently, the main measurement method is manual inspection using specific calipers, which is characterized by an extremely large workload, poor timeliness, and low level of digitalization, seriously affecting the efficiency of on-site maintenance and repair, and severely hindering the timely detection of potential hazards.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] Example 1

[0032] Figure 1 This is a flowchart illustrating a method for measuring the locking amount of an externally locked turnout according to Embodiment 1 of the present invention. This method is applied to an externally locked turnout locking amount measurement system, which includes an externally locked turnout device and a data measurement subsystem. Figure 2 This is a schematic diagram of an externally locking turnout device provided in an embodiment of the present invention, for reference. Figure 2 The device includes a locking hook 10, an actuating lever 20, a locking iron 30, a locking frame 40, a sensing element 50, and a magnetic grid 60. Figure 2 (not shown in the image) and magnetic head 70 ( Figure 2 (Not shown in the image). The locking hook 10 and the actuating lever 20 are both located within the locking frame 40. The locking iron 30 is fixed above the locking frame 40. The sensing element 50 is built into the locking iron 30 to sense the distance data to the locking hook 10. The actuating lever 20 has a built-in magnetic grid 60. A locking frame stop 41 is fixedly connected to the locking frame 40. A magnetic head 70 is built into the locking frame stop 41 to measure the displacement data of the actuating lever 20. The data measurement subsystem is communicatively connected to the sensing element 50 and the magnetic head 70, respectively. Figure 1 As shown, the method includes:

[0033] S110. When the actuator starts to move along the contact surface with the locking hook, the distance data detected by the sensing element and the displacement data measured by the magnetic head are acquired until the actuator stops moving.

[0034] Specifically, Figure 3 This is a schematic diagram of the action rod structure provided in an embodiment of the present invention, for reference. Figure 1 , Figure 2 , Figure 3During the locking process of the externally locking turnout, the actuating lever 20 moves along the contact surface with the locking hook 10. Locking is completed at the end of the movement, and correspondingly, the upper surface of the locking hook 10 begins to descend. At this time, the sensing element 50 inside the locking iron 30 detects the moving distance of the locking hook 10. The magnetic grid 60 is embedded in the actuating lever 20, and the locking frame stop 41 has a built-in magnetic head 70. Figure 3 (Not shown in the image) It can sense changes in the magnetic field of the magnetic grating to obtain specific displacement data of the actuating rod 20. The data measurement subsystem is communicatively connected to the sensing element 50 and the magnetic head 70 to obtain the corresponding data. Among them, by using the sensing element 50, the magnetic head 70 and the magnetic grating 60, the position of the locking hook and the full-stroke displacement monitoring of the actuating rod of the turnout can be realized in a non-contact manner without changing the existing turnout structure, without drilling holes in the rails, and without adding tooling fixtures to the turnout.

[0035] S120. Determine the locking amount of the external locking turnout based on the distance and displacement data.

[0036] In an optional embodiment, the above step of determining the locking amount of the externally locking turnout based on the distance data and the displacement data includes:

[0037] Based on the distance data, determine the first distance value change time point; the first distance value change time point is the time point in the distance data when the distance value changes from zero to non-zero.

[0038] Specifically, the turnout switching process is divided into multiple stages, namely, unlocking, switching, and locking. In the unlocking stage, the actuating lever 20 and the locking hook 10 have a contact surface. The actuating lever 20 moves along the contact surface first, while the locking hook 10 remains stationary. When the locking hook 10 starts to move, the switching stage begins. The upper surface of the locking hook 10 begins to descend, and the data of the sensing element 50 changes. At this time, it can be determined that the unlocking stage is completed. That is, the first distance value change point in the distance data from zero distance value to non-zero distance value is the time point when the unlocking stage is completed.

[0039] Determine the first target displacement value at the time point when the first distance value changes in the displacement data.

[0040] The first target displacement value is determined as the locking amount of the externally locked turnout.

[0041] Specifically, the locking amount is the same in the unlocking and locking phases, both being the locking amount of the externally locked turnout. Therefore, based on the distance data, the first distance value change time point is determined, that is, after determining the unlocking phase, the locking amount of the externally locked turnout is determined based on the displacement value of the action rod 20 under the unlocking phase, that is, the first target displacement value.

[0042] This invention provides a method for measuring the locking amount of an externally locking turnout, applied to an externally locking turnout locking amount measurement system. The system includes an externally locking turnout device and a data measurement subsystem. The device comprises a locking hook, an actuating rod, a locking iron, a locking frame, a sensing element, a magnetic grating, and a magnetic head. The locking hook and actuating rod are both located within the locking frame, the locking iron is fixed above the locking frame, and the sensing element is built into the locking iron to sense the distance data between the locking hook and the actuating rod. The actuating rod has a built-in magnetic grating, a locking frame stop is fixedly connected to the locking frame, and the magnetic head is built into the locking frame stop to measure the displacement data of the actuating rod. The data measurement subsystem is communicatively connected to both the sensing element and the magnetic head. This method is executed by the data measurement subsystem. When the actuating rod is detected to begin moving along the contact surface with the locking hook, the distance data detected by the sensing element and the displacement data measured by the magnetic head are acquired until the actuating rod stops moving. Finally, the locking amount of the externally locking turnout is determined based on the distance and displacement data. The above technical solution solves the problems of high workload, low timeliness, and low digitalization caused by manual measurement of locking amount. Through multi-dimensional data fusion analysis, the key position information of the locking hook of the external locking device is obtained based on the characteristics of the position sensor data parameters. According to the locking hook position information, the stages of the turnout conversion process are accurately distinguished, thereby accurately determining the locking amount of the external locking turnout and further improving the operation and maintenance efficiency of rail transit turnout signal products.

[0043] Example 2

[0044] Figure 4 This is a flowchart illustrating a method for measuring the locking amount of an externally locking turnout according to Embodiment 2 of the present invention. This embodiment provides a preferred example based on the above embodiments.

[0045] like Figure 4 As shown, the method includes the following specific steps:

[0046] S210. When the actuator starts to move along the contact surface with the locking hook, the distance data detected by the sensing element and the displacement data measured by the magnetic head are acquired until the actuator stops moving.

[0047] S220. Based on the distance data, determine the time point when the second distance value changes; the time point when the non-zero distance value in the distance data does not change.

[0048] Specifically, since the turnout switching process is divided into three stages: unlocking, switching, and locking, in the unlocking stage, the actuating lever 20 and the locking hook 10 have a contact surface. The actuating lever 20 moves along the contact surface first, while the locking hook 10 remains stationary. When the locking hook 10 starts to move, the switching stage begins, the upper surface of the locking hook 10 begins to descend, and the data of the sensing element 50 changes to a non-zero distance value. When the non-zero distance value no longer changes, it can be determined that the switching stage is complete and the locking stage begins. That is, the time point when the non-zero distance value in the distance data no longer changes is the time point for entering the locking stage.

[0049] S230. Based on the second distance change time point and the stop movement time point of the action rod, determine the second target displacement value based on the displacement data.

[0050] Specifically, the second distance change time point is the time point when entering the locking stage, and the time point when the actuator stops moving is the time point when the locking stage is completed. The movement data of the actuator within these two time points is the locking amount of the locked turnout outside the locking stage, which is also the second target displacement value.

[0051] S240. The second target displacement value is determined as the locking amount of the external locking turnout.

[0052] Optionally, step S230 above, determining the second target displacement value based on displacement data according to the second distance change time point and the stop movement time point of the moving member, includes:

[0053] Determine the first reference displacement value at the time point of change of the second distance value in the displacement data; and,

[0054] Determine the second reference displacement value at the point when the moving member in the displacement data stops moving;

[0055] Among them, the first reference displacement value at the time point of change of the second distance value in the displacement data is the displacement value of the action link in the transition phase, and the second reference displacement value at the time point when the action link stops moving in the displacement data is the displacement value of the action link in the transition phase and the locking phase.

[0056] The second target displacement value is determined based on the first reference displacement value and the second reference displacement value.

[0057] For example, the difference between the second reference displacement value and the first reference displacement value is determined as the second target displacement value.

[0058] This invention provides a method for measuring the locking amount of an externally locked turnout. Based on distance data, a second distance value change time point is determined. This second distance value change time point is the time point when the non-zero distance value in the distance data does not change. Based on the second distance change time point and the time point when the moving rod stops moving, a second target displacement value is determined based on displacement data. Finally, the second target displacement value is determined as the locking amount of the externally locked turnout. This technical solution can accurately identify the locking stage of the externally locked turnout, thereby accurately identifying the locking amount and further improving the operation and maintenance efficiency of rail transit turnout signal products.

[0059] This invention also provides a locking amount measurement system for externally locking turnouts. The system includes an externally locking turnout device and a data measurement subsystem. The externally locking turnout device includes a locking hook, an actuating rod, a locking iron, a locking frame, a sensing element, a magnetic grating, and a magnetic head. The locking hook and actuating rod are both located within the locking frame. The locking iron is fixed above the locking frame. The sensing element is built into the locking iron to sense the distance data between the locking hook and the actuating rod. The actuating rod has the magnetic grating built into it. A locking frame stop is fixedly connected to the locking frame. The magnetic head is built into the locking frame stop and is used to measure the displacement data of the actuating rod. The data measurement subsystem is communicatively connected to both the sensing element and the magnetic head. The data measurement subsystem acquires the distance data detected by the sensing element and the displacement data measured by the magnetic head when it detects that the actuating rod has begun to move along the contact surface with the locking hook, until the actuating rod stops moving. Based on the distance data and displacement data, the locking amount of the externally locking turnout is determined.
