[0051] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related application, and not to limit the application. In addition, it should be noted that only parts related to the application are shown in the drawings for ease of description.

[0052] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0053] There are many types of turnouts, commonly used are single turnout, symmetrical turnout, triple turnout and split turnout, the inventive concept of the present application is applicable to various types of turnouts, and a single turnout is taken as an exemplary description in the embodiments of the present application.

[0054] A turnout is composed of turnout beams, finger-shaped handle sets, cross-shaped hinges, tail shaft devices and other components. The turnout beams are connected by finger-shaped handle sets that can rotate with each other and T-shaped shafts that can rotate up and down and horizontally. The finger-shaped handle sets eliminate the gap between adjacent turnout beams, and the cross-shaped hinges and tail shafts can ensure that the turnout generates a corner change when it rotates, and drive the related beams to rotate. The drive system of the turnout drives the swing arm to rotate around the center shaft of the reducer to realize the horizontal movement of the turnout beam.

[0055] Please see Figure 1 A method for monitoring a turnout opening position, the method comprising:

[0056] S1, a preset reference position and an opening position of a turnout are set. The opening position is a position corresponding to a branch of the turnout, and the opening position indicates a passing direction of a train on the turnout. In the turnout, the switch machine can also indicate the position of the switch core.

[0057] S2, a preset distance interval is set based on the reference position and the opening position.

[0058] In the embodiments of the present application, the existence of errors is allowed when setting the preset distance interval. In the embodiments of the present application, the preset distance interval range is the distance range of the turnout rotatable part and the allowed error, and the preset distance interval range is used to determine whether the turnout is in the opening position.

[0059] S3, a real-time distance of the turnout rotatable part to the reference position is obtained.

[0060] The detection of the turnout rotation distance is related to the type of turnout. According to the type of turnout, the rotation distance of the turnout rotatable part can be directly detected, or the rotation distance of the synchronously rotating component of the rotatable part can be indirectly detected. According to the convenience of the detection of the turnout rotation distance, the detection method of the rotation distance is determined.

[0061] S4, it is determined whether the real-time distance is within the preset distance interval.

[0062] S5, if the real-time distance is within the preset distance interval, an indication signal of the opening position is output, and the indication signal is used to indicate whether the turnout is in the opening position.

[0063] In the embodiments of the present application, the distance between the turnout rotatable part and the reference position is obtained in real time, and the distance is used to determine whether the turnout is in the opening position. Then, the signal is output to the outside, and the state of the turnout is determined by the signal. The indication signal of the opening position can be used to indicate whether the turnout is in the opening position. In the specific setting, the indication signal can include multiple signals, for example, a first signal. When the first signal is a closed signal, it indicates that the turnout is in the opening position. When the first signal is a disconnected signal, it indicates that the turnout is not in the opening position. The output form of the multiple signals is not specifically limited in the present application. In the following embodiments, several signals are illustratively given, and the application scenario can be adjusted in the specific setting.

[0064] In the embodiments of the present application, the preset reference position and the opening position of the turnout include:

[0065] S101, a preset rotation track of the turnout is set, and the preset rotation track includes an actual rotation track of the turnout.

[0066] S102, preset one position in the preset rotation track as a reference position;

[0067] The example is as follows Figure 2 , the A'-B' arc in the figure is the preset rotation track of the switch rotatable part, and the A-B arc is the actual rotation track of the switch rotatable part. A' can be defined as the reference position of the rotation distance, or B' can be defined as the reference position of the rotation distance.

[0068] S103, determining the branch opening of the switch based on the actual rotation track;

[0069] S104, determining the opening position based on the branch opening.

[0070] In the example provided in the embodiment of the present application Figure 2 In the example, it is assumed that the A-B arc is the actual rotation track of the switch rotatable part, and the branch opening (not shown) is located at A, and A is selected as the opening position.

[0071] It should be noted that the preset distance interval can be determined according to the performance of different switch systems, or can be configured by a user, and the present application does not limit this. In the embodiment of the present application, the opening position is determined based on the motion track of the switch rotatable part. In different embodiments, the motion track of the switch can be a straight line or a curve, and the present application does not limit this.

[0072] For example, the preset distance interval is set based on the reference position and the opening position, including:

[0073] S201, determining the actual distance from the opening position to the reference position of the switch rotatable part in the preset rotation track;

[0074] S202, obtaining the running allowable error of the switch rotatable part;

[0075] S203, calculating the preset distance interval based on the actual distance and the running allowable error.

[0076] It should be noted that the method for defining the preset distance interval adopted in the embodiment of the present application is to determine the motion track of the switch mechanical part, for example Figure 2 In the arc motion track of the switch rotatable part in the example, the distance from the position of the end point of the end to the reference position is defined. When the real-time distance of the switch is obtained, the preset distance interval is defined as the circumference of the arc.

[0077] Of course, in other embodiments, a straight-line distance can also be used as a reference for judgment. In the embodiments of the present application, the manner of setting the preset distance interval is not limited, and the real-time distance of the switchable part of the turnout to the reference position can be unified when it is acquired or after it is acquired. Regardless of the implementation, it falls within the protection scope of the present application.

[0078] In the embodiments of the present application, a position switch is preset at the opening position, and the position switch is closed when the turnout is turned to the position of the position switch, and the position switch is opened when the turnout leaves the position of the position switch.

[0079] In the embodiments of the present application, a position switch is preset at the opening position, and the position switch is closed when the turnout is turned to the position of the position switch, and the position switch is opened when the turnout leaves the position of the position switch.

[0080] In the embodiments of the present application, the distance between the switchable part of the turnout and the reference point and the state of the position switch preset at the opening position of the turnout are combined, and the turnout position is determined through certain logic of the two. The combination of the position switch and the distance measurement mode further improves the reliability of the turnout position monitoring and the safety of the system.

[0081] Further, as shown in Figure 3 The method further includes:

[0082] ST1, acquiring the state of the position switch in real time.

[0083] ST2, outputting a signal based on the state of the position switch; the state of the position switch is determined, and the output signal is determined based on the state of the position switch and whether the turnout is at the opening position.

[0084] ST3, if the real-time distance is within the preset distance interval and the position switch is closed, a first signal is output; the first signal indicates that the turnout is at the opening position, and the signal prompts the user to quickly acquire the position of the turnout.

[0085] ST4, if the real-time distance is within the preset distance interval and the position switch is opened, a second signal is output; the second signal indicates that the turnout device is faulty. The alarm information of the fault information prompts the user according to the alarm information, so that the user can quickly acquire the fault information for quick response and improve the user experience.

[0086] In a specific application, other conditions can also be set for the output of the second signal to ensure that the fault signal is more rigorous and prevent false alarms, for example, a delay time condition can also be set, for example, after a delay of 100 ms, the real-time distance is still within the preset distance interval and the position switch is still open, and the second signal is output. Of course, other conditions can also be set for limitation, and the embodiments of the application do not limit other conditions for signal output.

[0087] In a specific application, various signals, such as the first signal, the second signal, the third signal, etc., can be subject to other condition limitations according to the application scenario. Regardless of which limitation method is used, as long as it does not deviate from the inventive concept of the present application, it falls within the protection scope of the present application.

[0088] ST5, if the real-time distance is not within the preset distance interval and the position switch is open, output a third signal. The third signal represents that the turnout is in a four-open state, that is, neither in an open position nor in a fault, and generally indicates that the turnout is in a certain non-open position in the moving track through the four-open state.

[0089] In the embodiments of the present application, the open position includes a first position and a second position, the preset distance interval corresponding to the first position is a first preset interval, and the preset distance interval corresponding to the second position is a second preset interval.

[0090] It should be noted that the first position is a positioning, and the second position is a reverse position. The positioning and the reverse position limit the rotation direction of the rotatable part of the turnout. When rotated to the positioning, the rotatable part of the turnout moves in the direction from the positioning to the reverse position. When rotated to the reverse position, the rotatable part of the turnout moves in the direction from the reverse position to the positioning. It should be noted that the single-open turnout is exemplarily described in the embodiments of the present application. When the turnout is in the positioning, the turnout allows light rail or other vehicles to pass through. When the turnout is in the reverse position, the turnout prohibits light rail or other vehicles to pass through.

[0091] Two open positions are exemplarily described in the embodiments of the present application. In some other embodiments, multiple open positions can also be set, which needs to be exemplarily adjusted according to a specific application scenario. The present application does not limit this.

[0092] Among them, the first position is provided with a first position switch, and the second position is provided with a second position switch.

[0093] Specifically, the method comprises:

[0094] ST11, real-time acquisition of the state of the first position switch and the state of the second position switch;

[0095] ST12, outputting a signal based on the state of the first position switch and the state of the second position switch;

[0096] ST13, outputting a first position signal if the real-time distance is in the first preset interval and the first position switch is closed; the first position signal represents that the turnout is in a first position, for example, a positioning position.

[0097] ST14, outputting a second position signal if the real-time distance is in the second preset interval and the second position switch is closed; the second position signal represents that the turnout is in a first position, for example, a positioning position.

[0098] ST15, outputting a second signal if the real-time distance is in the first preset interval and the first position switch is open; the second signal represents that the turnout device is faulty. The alarm information of the fault information can prompt the user according to the alarm information, so that the user can learn the fault information in time to respond quickly and improve the user experience.

[0099] ST16, outputting a second signal if the real-time distance is in the second preset interval and the second position switch is open; the second signal represents that the turnout device is faulty. The alarm information of the fault information can prompt the user according to the alarm information, so that the user can learn the fault information in time to respond quickly and improve the user experience.

[0100] ST17, outputting a second signal if the real-time distance is not in the first preset interval and the second preset interval, and the first position switch is closed or the second position switch is closed; the second signal represents that the turnout device is faulty. The alarm information of the fault information can prompt the user according to the alarm information, so that the user can learn the fault information in time to respond quickly and improve the user experience.

[0101] ST18, outputting a third signal if the real-time distance is not in the first preset interval and the second preset interval, and the first position switch is open and the second position switch is open; the third signal represents that the turnout is in a four-open state, that is, neither in an open position nor in a fault state, which generally represents that the turnout is in a certain non-open position in the moving track.

[0102] For example, a single turnout is taken as an example for illustrative description, as shown in Figure 2 , it is assumed that the A' position is the reference position for detecting the rotation distance (at this time, the real-time distance is 0).

[0103] The first position (positioning) in the switch opening position is determined as position A, and the rotating distance value A' A (assuming 1.00 meters) and its allowable error of +0.05 meters or -0.05 meters are assumed; the rotating distance (preset distance interval) of the first position of the switch is in the range of 0.95 meters to 1.05 meters.

[0104] The second position (reverse position) in the switch opening position is determined as position B, and the rotating distance value A' B (assuming 10.00 meters) and its allowable error of +0.05 meters or -0.05 meters are assumed; the rotating distance (preset distance interval) of the second position of the switch is in the range of 9.95 meters to 10.05 meters.

[0105] A distance measuring device is installed in the switch driving part to measure the rotating distance L in real time.

[0106] A first position switch Kd is installed at the positioning position of the switch, which is closed when the rotatable part of the switch rotates to the positioning position, and is opened when the rotatable part of the switch leaves the positioning position.

[0107] A second position switch Kf is installed at the reverse position of the switch, which is closed when the rotatable part of the switch rotates to the reverse position, and is opened when the rotatable part of the switch leaves the reverse position.

[0108] The opening and closing states of Kd and Kf and the distance L between the rotatable part and the reference position are detected in real time; as shown in Figure 4 .

[0109] 1) When 0.95≤L≤1.05 and Kd is in the closed state, the switch positioning output (first position signal) indicates to give a closed signal to show that the switch is in the positioning position.

[0110] 2) When 0.95≤L≤1.05 and Kd is in the open state, after a delay of 100 ms, it is still 0.95≤L≤1.05 and Kd is in the open state, then the switch fault output (second signal) indicates to give a closed signal to show that the switch equipment is faulty.

[0111] 3) When 9.95≤L≤10.05 and Kf is in the closed state, the switch reverse position output (second position signal) indicates to give a closed signal to show that the switch is in the reverse position.

[0112] 4) When 9.95≤L≤10.05 and Kf is in the open state, after a delay of 100 ms, it is still 9.95≤L≤10.05 and Kf is in the open state, then the switch fault output (second signal) indicates to give a closed signal to show that the switch equipment is faulty.

[0113] 5) when L is neither in the range of 0.95≤L≤1.05 nor in the range of 9.95≤L≤10.05, and Kd and Kf are both in the open state, for example, in the Figure 2 When the switch is in the fourth position, the fourth signal output (third signal) indicates that the switch is in the fourth position.

[0114] 6) when L is neither in the range of 0.95≤L≤1.05 nor in the range of 9.95≤L≤10.05, and Kd or Kf is in the closed state, the switch fault output (second signal) indicates that the switch device is faulty.

[0115] It should be noted that in the embodiments of the present application, only one state of a signal is exemplarily given in a certain state. Since three states of signals are shown in the embodiments of the present application, for example, when the first signal is in the closed state, it indicates that the switch is in the open position, but at the same time, the other signals, for example, the second signal and the third signal, are in the open state, indicating that there is no fault or the switch is not in the fourth position. The present application will not be described here.

[0116] In a second aspect, as shown in Figure 5 The present application provides a monitoring system for a switch open position, which comprises:

[0117] An initial module 100 is configured to preset a reference position and an open position of the switch, and set a preset distance interval based on the reference position and the open position.

[0118] A distance measuring module 200 is configured to acquire a real-time distance from the reference position of a rotatable part of the switch.

[0119] A judging module 300 is configured to judge whether the real-time distance is within the preset distance interval.

[0120] An output module 400 is configured to output an indication signal of the open position if the real-time distance is within the preset distance interval.

[0121] A position switch 500 is configured to be preset in the open position. When the switch is turned to the position of the position switch, the position switch is closed. When the switch is away from the position of the position switch, the position switch is open.

[0122] Further, the judging module 300 is further configured to acquire a state of the position switch in real time, and output the indication signal of the open position based on the state of the position switch.
