Description

Technical Field

[0001] This invention relates to turnout control technology, and in particular to a method, apparatus, equipment and medium for analyzing the consistency of turnout representation indoors and outdoors based on turnout close-fitting data acquisition. Background Technology

[0002] A turnout is a track connection device that allows locomotives and rolling stock to switch from one track to another. It is one of the most critical pieces of equipment in rail transit signaling and also one of the weakest links in the track. Therefore, turnout fault diagnosis and maintenance are key issues in rail transit signaling maintenance. Currently, the determination of turnout positioning and reversal is done through indoor positioning relays and reversal indication relays. This method relies on manual testing to ensure consistency between indoor and outdoor testing. Once a negligence occurs in the manual process, it can easily lead to major and catastrophic safety problems. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a method, device, equipment and medium for analyzing the consistency of turnout representation indoors and outdoors with high acquisition efficiency and strong real-time performance.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] According to a first aspect of the present invention, a method for analyzing the consistency of turnout indication between indoor and outdoor areas is provided. This method calculates the position of the outdoor turnout based on the acquisition of the turnout's contact value and performs real-time consistency analysis with the indoor turnout indication relay.

[0007] As a preferred technical solution, the calculation process for the outdoor turnout contact value includes: calculating the contact value based on the initial contact value and the contact offset value. The specific calculation process is as follows:

[0008] Fit value = Initial fit value + Fit offset value.

[0009] As a preferred technical solution, the initial contact value is obtained by setting it.

[0010] As a preferred technical solution, the close offset value is distinguished into different types according to the installation position of each acquisition module, and different calculation formulas are used for different types.

[0011] As a preferred technical solution, if the basic rail acquisition module and the switch rail acquisition module are on the same side, the left side close-fit offset value is equal to the change of the left basic rail after movement minus the change of the left switch rail.

[0012] As a preferred technical solution, if the basic rail acquisition module and the switch rail acquisition module are on different sides, the left side close-fit offset value is equal to the change of the left basic rail after movement plus the change of the left switch rail.

[0013] As a preferred technical solution, the turnout indication judgment process based on the close contact value is specifically as follows: the position of the outdoor turnout is determined according to the current close contact values ​​on the left and right sides and the turnout opening direction set in the previous period.

[0014] As a preferred technical solution, the turnout opening configuration set in the early stage includes positioning on the left and positioning on the right.

[0015] As a preferred technical solution, the actual position of the outdoor turnout includes both the initial and reverse positions.

[0016] As a preferred technical solution, the process for determining the consistency of indoor and outdoor turnout representations is as follows:

[0017] The consistency of the outdoor turnout position with the status of the indoor turnout indicator relay is compared.

[0018] As a preferred technical solution, the consistency comparison specifically refers to:

[0019] The system checks the consistency of the turnout's indoor and outdoor displays every second. If the inconsistency persists within the T1 time period, an error message is given. If the consistency persists within the T1 time period, the error message is restored.

[0020] As a preferred technical solution, T1 is configurable and is initially set to 5 seconds.

[0023] The turnout indication judgment module is used to determine the outdoor turnout indication based on the close-fitting value.

[0025] According to a third aspect of the present invention, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the program to implement the method described thereon.

[0026] According to a fourth aspect of the present invention, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, implements the method described thereon.

[0035] Figure 4 This is a schematic diagram illustrating the real-time measurement data acquisition method of the present invention. Detailed Implementation

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0037] This invention discloses a method for analyzing the consistency of turnout indication between indoor and outdoor locations. This method calculates the outdoor turnout position based on the collected turnout contact values ​​and performs real-time consistency analysis with the indoor turnout indication relay. The specific process is as follows:

[0038] 1) Based on the actual turnout conditions on site, determine the turnout direction (left side or right side) and the installation position of the data acquisition module (left side or right side), which will serve as a prerequisite for determining the outdoor positioning and reversal of the switch machine.

[0039] 2) Acquire real-time measurement data, including: A1-left basic rail crawl measurement value, A2-right basic rail crawl measurement value, A3-J1 left basic rail measurement value, A4-J1 right basic rail measurement value, A5-J1 left switch rail measurement value, and A6-J1 right switch rail measurement value, such as... Figure 4 As shown;

[0040] 3) Logically calculate the close distance between the left and right base rails and the switch rails of J1. The distance between the left base rail and the switch rail of J1 = the measured value of the left base rail of J1 (A3) - the measured value of the left switch rail of J1 (A5). The distance between the right base rail and the switch rail of J1 = the measured value of the right base rail of J1 (A4) - the measured value of the right switch rail of J1 (A6).

[0041] 4) When the distance between the left / right basic rail and the switch rail of J1 is less than or equal to 2mm, it is considered that the side is in close contact. As shown in the figure, the right side is considered to be in close contact.

[0042] 5) Determine the outdoor position of the turnout based on the turnout opening direction (left side or right side) and the close contact value on the left and right sides. For example, if the turnout is positioned on the left side, it is considered that the turnout is in the reverse position as shown in the figure.

[0043] 6) The suction / drop status of indoor DBJ and FBJ is obtained through the monitoring of switch signals;

[0044] 7) Provided that there are indications both indoors and outdoors (the distance (close contact value) between the basic rail and the switch rail on the left / right side of J1 is less than or equal to 2mm, and the indoor DBJ or FBJ is lifted), the consistency of the indoor and outdoor indications of the turnout is judged every second. If the inconsistency continues within the T1 time period, an abnormal prompt is given. If the consistency continues within the T1 time period, the abnormal prompt is restored. Specific embodiment:

[0046] like Figure 1 As shown, a method for analyzing the consistency between indoor and outdoor turnout representations based on outdoor close-fitting data collection is presented. This method includes the following steps:

[0047] Step 1: After the equipment is installed, obtain the following information based on the installation status of the turnout and switch machine, including the turnout direction (left side, right side), the measurement value of the A3-J1 left main rail, the measurement value of the A4-J1 right main rail, the measurement value of the A5-J1 left switch rail, and the installation position (left side, right side) of the measurement value acquisition module for the A6-J1 right switch rail.

[0048] Note: The left and right sides are defined with the rail facing the switch point in front.

[0049] Step 2: Based on the installation position of each acquisition module (left or right), differentiate between different types and apply different calculation formulas for each type. When the basic rail acquisition module and the switch rail acquisition module are on the same side, calculate the left side contact offset value = (A3'-A5')-(A3-A5). When the basic rail acquisition module and the switch rail acquisition module are on different sides, calculate the left side contact offset value = (A3+A5)-(A3'+A5'). See the specific logic below. Figure 2 (Taking the left side as an example);

[0050] Step 3: Based on the initial contact value set and the contact offset value calculated in Step 2, calculate the current contact value. Contact value = initial contact value + contact offset value.

[0051] Step 4: Determine the position of the outdoor turnout (positioned or reversed) based on the current left and right side contact values ​​and the previously set turnout opening direction (positioned left, positioned right).

[0052] Step 5, compare the consistency with the indoor turnout indicator relay status: check the consistency between the indoor and outdoor turnout indications every second. If the inconsistency continues within the T1 period (initially set to 5 seconds, configurable), an error message will be given. If the consistency continues within the T1 period (initially set to 5 seconds, configurable), the error message will be restored.

[0053] Step 2 will be explained in detail. If the basic rail acquisition module and the switch rail acquisition module are on the same side, such as... Figure 2 The dotted line represents the position after the movement. At this time, the left side offset value is equal to the change of the left basic rail after the movement minus the change of the left tip rail, i.e., (A3'-A5')-(A3-A5).

[0054] If the basic rail acquisition module and the switch rail acquisition module are on different sides, such as Figure 3 The dotted line represents the position after the movement. At this time, the left side offset value is equal to the change of the left basic rail plus the change of the left tip rail after the movement, i.e., (A3-A3')+(A5-A5').

[0055] This invention will be applied to the Intelligent Operational & Maintenance System (IOM) of the subway signaling system. The IOM system is an auxiliary tool for equipment status monitoring and maintenance of the entire rail transit signaling system. It has interfaces with subsystems such as Automatic Train Supervision (ATS), ATP / ATO (Automatic Train Protection System / Automatic Train Operation), Computer Based Interlocking (CBI), and communication. Through the above interfaces and real-time acquisition of the status of key equipment, alarms are generated in a timely manner for faulty equipment, the maintenance dispatch is notified, and the relevant maintenance operation process is initiated.
