Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a non-contact type connector alignment monitoring device and method. Background Art

[0002] A railway coupler is an important device used on railways or rail vehicles, and is one of the components of a railway vehicle system. It is used to connect completed railway trains or rail vehicles to ensure that when the locomotive or the power car in a fixed train set is started, it can drive the unpowered railway passenger car or railway freight car, so that they can be synchronously linked at the same time under their physical force, thereby ensuring the smooth operation of the entire rail train.

[0003] The electro-pneumatic braking system currently used in trains needs to be installed on the trains in the electrical system and communication system of each train, and electrical and communication connections are required between each train. In the existing electro-pneumatic control system, the communication lines are mostly connected by cables. When reorganizing or disassembling the train, it is necessary not only to connect the brake air ducts of each vehicle in the train, but also to connect the communication lines, which makes the operation complicated. In addition, the cables between the vehicles in the train are connected with connectors. Since the cross-marshaling of trains is very frequent, and the life of the mechanically connected connectors is limited, usually not more than 500 times, the cable connector is a fault-prone link in the communication line, increasing the maintenance and repair costs; and when the two mating interfaces of adjacent connectors interact with each other, the inevitable wear and friction will cause a series of contact-related failures and maintenance problems.

[0004] Based on this, contactless connectors are the current development direction, but if the connector plug and the connector socket of the contactless connector are not aligned, especially when the train turns, there is a risk of train derailment, safety accidents are prone to occur, and the communication function between the connectors is easily affected. Summary of the invention

[0005] The purpose of the present invention is to overcome the problem that the prior art lacks a device for detecting whether a non-contact connector is aligned during a train turning process, resulting in the risk of train derailment and unstable signal transmission, and provides a non-contact connector alignment monitoring device and method, which can determine whether the connector is aligned during a turning process, and can adjust the non-contact connector to align it when it is not aligned, thereby improving the safety of the train during the turning process and the signal transmission quality.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: a non-contact connector alignment monitoring device, comprising:

[0007] The turning judgment module is used to judge whether the train has entered the turning process and determine the turning direction;

[0008] A laser device is used to initially determine whether the connector is aligned;

[0009] A signal monitoring device for monitoring the quality of signal transmission between the connector plug and the connector socket;

[0010] A control system, used for receiving the preliminary judgment result of the laser device and the signal transmission data of the signal monitoring device, and sending a control signal to the alignment device according to the distance data and the signal transmission data;

[0011] The alignment device is used to control the alignment of the connector according to the control signal of the control system.

[0012] The upper and lower terminals of the connector should correspond to the plug and socket or the male and female ends of the connector. The plug and socket of the contactless connector do not contact each other. This application is to determine whether the plug and socket of the contactless connector are aligned. Connector alignment means that the plug and socket of the connector are aligned. When working, the turning judgment module first determines whether the train enters a turn. If the train enters a turn, the control system controls the laser device and the signal monitoring device to start working. The laser device can obtain the distance between the connector plug and socket, or directly determine whether the connector is aligned based on whether the laser can be received, and send the judgment result to the control system. The signal monitoring device obtains the signal transmission quality between the contactless connector plug and socket and sends the result to the control system. The control system combines the data of the laser device and the signal monitoring device to determine whether the contactless connector is aligned, and adjusts the alignment device according to the judgment result. The alignment device controls the adjustment of the angle between the terminals of the contactless connector to ensure the alignment of the contactless connector and the quality of signal transmission.

[0013] Preferably, the control system comprises:

[0014] A judging module, used for judging whether the connectors are aligned according to the calculation results of the laser device and the signal monitoring device;

[0015] A current control module, used to adjust the magnitude and direction of the current flowing to the alignment device according to the judgment result of the judgment module;

[0016] The communication module is used to send the calculation results of the laser device and the signal monitoring device and the judgment results of the judgment module to the server.

[0017] When entering a curve, the angle between the central axis of the connector plug and the socket decreases from 180°. Due to centrifugal force, the distance between the contactless connector plug and the socket may increase, causing the two to be misaligned. At this time, the current control module changes the direction of the current flowing to the alignment device and changes the magnitude of the current flowing to the alignment device as needed. When exiting a curve, the angle between the central axis of the connector plug and the socket gradually changes back to 180°. At this time, the current control module changes the direction of the current flowing to the alignment device again and changes the magnitude of the current flowing to the alignment device as needed. This is the working mode of the alignment device, and the present application is used to monitor whether the connector plug and socket are aligned. When misaligned, the distance between the connector plug and the socket can also be adjusted by adjusting the magnetic force of the electromagnet to align them.

[0018] Preferably, the alignment device comprises electromagnets evenly and spacedly distributed on the edges of the connector plug and the connector socket, and the electromagnets are connected to a control system.

[0019] Electromagnets are installed in both the connector plug and the connector socket. The electromagnets are evenly and spaced apart on the edge of the plug, so as to avoid the plug facing the socket. For example, if the plug is circular, the electromagnets are evenly and spaced apart on the circumference. The alignment device in the present application is completed by the electromagnets installed on the connector plug and the socket. The control system controls the magnetic force of the electromagnet by the current flowing to the electromagnet, and then adjusts the angle of the connector plug and the socket to achieve alignment. Specifically, when entering the curve, the angle between the central axis of the connector plug and the socket decreases from 180°. Due to the centrifugal force, the distance between the contactless connector plug and the socket may increase, resulting in misalignment between the two. At this time, the current control module changes the direction of the current flowing to the alignment device, and the two electromagnets attract each other to complete the alignment, and the current size flowing to the alignment device is changed as needed, so that the repulsive force between the two electromagnets becomes an attractive force. When exiting the curve, the angle between the central axis of the connector plug and the socket gradually changes back to 180°. At this time, the current control module changes the direction of the current flowing to the alignment device again so that the attractive force between the two electromagnets becomes a repulsive force, and the current size flowing to the alignment device is changed as needed. This is the working mode of the alignment device, and this application is used to monitor whether the connector is aligned after the alignment device works. The electromagnets evenly distributed on the connector plug and socket can accurately control the magnetic force of some electromagnets according to the specific angle between the connector plug and the socket, thereby ensuring the alignment of the connector plug and the socket.

[0020] Preferably, the laser device comprises:

[0021] A laser transmitter, comprising a laser receiver, a laser signal demodulation and identification circuit and an intelligent control signal output circuit connected in sequence, for emitting laser;

[0022] The laser receiver comprises a laser receiver, a laser signal demodulation and identification circuit and an intelligent control signal output circuit which are connected in sequence and is used for receiving the laser from the laser transmitter.

[0023] The laser transmitter includes a laser connected in sequence, a voltage-stabilized constant current drive circuit, and an intelligent control circuit. There are three lasers, one installed in the center of the connector plug and two lasers distributed on the edge of the connector plug and symmetrical to the center; the laser receiver includes a laser receiver connected in sequence, a laser signal demodulation and identification circuit, and an intelligent control signal output circuit; there are three laser receivers, one installed in the center of the connector socket and two laser receivers distributed on the edge of the connector socket and symmetrical to the center. Through three lasers and three laser receivers, it is possible to more accurately determine whether the connector is aligned, thereby achieving precise control. The use of three lasers is to prevent the situation where the center position of the connector plug and the socket remains relatively unchanged, but the connector is still not aligned, because at this time the central laser receiver can still receive the laser emitted by the laser, but the edge cannot receive it.

[0024] On the other hand, the principle of laser beaming can also be used to determine whether the train is entering a turning process. When driving on a straight section, the connectors are aligned, and the angle between the central axis of the connector plug and the socket is 180 degrees. The laser receiver at the center of the connector socket can accurately receive the laser emitted by the laser at the center of the connector plug. When turning, the angle between the central axis of the connector plug and the socket decreases from 180 degrees, and the laser receiver at the center of the connector socket cannot receive the laser emitted by the laser at the center of the connector plug. Therefore, it can be determined whether the train is entering a turning process.

[0025] A non-contact connector alignment monitoring method comprises the following steps:

[0026] S1: Determine whether the train is in the process of turning and determine the turning direction;

[0027] S2: Acquire data from the laser device and the signal monitoring device to obtain judgment data;

[0028] S3: judging whether the connectors are aligned according to the judgment data;

[0029] S4: If the connectors are not aligned, adjust the angle between the connector plug and the connector socket to align the connectors.

[0030] The data from the laser device and the signal transmission quality are combined to determine whether the connector plug and socket are aligned, making the judgment result more accurate.

[0031] Preferably, the step S1 is further expressed as:

[0032] S1.1: Perform non-dynamic modeling on the connector and calculate the velocity vector of each point on the connector through filtering trajectory;

[0033] S1.2: Calculate the increment of the velocity vector of the current point and the projection value of the velocity vector increment of the current point in the normal direction of the track surface of the previous point, and determine the turning direction of the single point according to the size of the projection value;

[0034] S1.3: Perform sliding window statistics on the turning directions calculated at multiple points on the connector to obtain the statistically determined turning direction to determine the turning direction of the train.

[0035] The turning direction can be compared with the final magnetic force of the electromagnet to determine whether the adjustment result is reliable. For example, when turning left, the centrifugal force on the left and right sides of the connector is different. In order to ensure alignment, the magnetic force of the electromagnet on the left and right sides of the connector will also be different. Furthermore, a three-axis acceleration sensor can be installed on the connector to determine the turning angle.

[0036] Preferably, in step S3, the specific method of determining whether the connectors are aligned is:

[0037] A: If the laser receiver can receive the laser emitted by the laser, and the signal transmission quality changes within the threshold range, it means that the connectors are aligned;

[0038] B: If the laser receiver can receive the laser emitted by the laser, and the signal transmission quality change exceeds the threshold range, measure again. If the measurement result does not change, adjust the angle between the connector plug and the connector socket according to the signal transmission quality and measure again;

[0039] C: If at least one of the laser transmitters cannot receive the laser light emitted by the laser, and the signal transmission quality changes beyond the threshold range, it means that the connector is not aligned;

[0040] D: If at least one of the laser transmitters cannot receive the laser emitted by the laser, and the signal transmission quality changes within the threshold range, measure again. If the measurement result does not change, adjust the angle between the connector plug and the connector socket according to the laser device and measure again.

[0041] Preferably, the magnetic force of the electromagnet is adjusted according to the judgment result. If the distance between the connector plug and the connector socket increases, the magnetic force of the electromagnet is increased; if the distance between the connector plug and the connector socket decreases, the magnetic force of the electromagnet is reduced. The adjustment can apply different magnetic forces to different electromagnets according to the specific judgment result and the turning direction of the train.

[0042] Specifically, the electromagnets are evenly and spacedly distributed on the edges of the connector plug and socket. If the distance between the left end of the connector plug and the socket is measured to be farther than that between the right end, the current at the left end can be controlled to increase to increase the attraction of the electromagnet; the current at the left end can be controlled to increase to increase the attraction of the electromagnet; the current at the right end can be controlled to increase to reduce the attraction of the electromagnet.

[0043] Therefore, the present invention has the following beneficial effects: 1. It can determine whether the non-contact connector plug and socket are aligned during the turning process, thereby realizing the monitoring of the non-contact connector; 2. When the non-contact connector plug and socket are not aligned during the turning process of the train, the non-contact connector can be adjusted to align them, thereby improving the safety of the train during the turning process and the signal transmission quality, and ensuring the safety of the train.

[0047] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0048] Embodiment 1:

[0049] This embodiment is a non-contact connector alignment monitoring device, such as Figure 1 As shown, it includes: a control system 1 and a turning judgment module 2, a laser device 3, a signal monitoring device 4 and an alignment device 5 connected to the control system. The control system is used to receive the preliminary judgment result of the laser device and the signal transmission data of the signal monitoring device, and send a control signal to the alignment device according to the distance data and the signal transmission data; the turning judgment module is used to judge whether the train enters the turning process and judge the turning direction; the laser device is used to preliminarily judge whether the connector is aligned; the signal monitoring device is used to monitor the signal transmission quality between the connector plug and the connector socket; the alignment device is used to control the connector alignment according to the control signal of the control system.

[0050] When working, the turning judgment module first determines whether the train has entered a turn. If the train has entered a turn, the control system controls the laser device and the signal monitoring device to start working. The laser device can obtain the distance between the connector plug and the socket, or directly determine whether the connector is aligned based on whether the laser can be received, and send the judgment result to the control system. The signal monitoring device obtains the signal transmission quality between the non-contact connector plug and the socket and sends the result to the control system. The control system combines the data of the laser device and the signal monitoring device to determine whether the non-contact connector is aligned, and adjusts the alignment device according to the judgment result. The alignment device controls the adjustment of the angle between the non-contact connector terminals to ensure the alignment of the non-contact connector and the quality of signal transmission.

[0051] Specific:

[0052] The control system includes a judgment module 6 for judging whether the connector is aligned according to the calculation results of the laser device and the signal monitoring device; a current control module 7 for adjusting the current size and current direction flowing to the alignment device according to the judgment result of the judgment module; and a communication module 8 for sending the calculation results of the laser device and the signal monitoring device and the judgment result of the judgment module to the server 10; the judgment module is respectively connected to the laser device, the signal monitoring device, the current control module, and the communication module, the communication module is also connected to the laser device and the signal monitoring device, and the current control module is connected to the alignment device.

[0053] This embodiment also includes a power supply module for providing power to the electromagnet, and the current control module is used to control the magnitude of the current flowing from the power supply module to the electromagnet.

[0054] The alignment device includes an electromagnet 9 connected to a current control module. In this embodiment, the electromagnets are evenly and spacedly distributed on the edge of the connector end. There are two current control modules, one for controlling the electromagnet of the upper connector and the other for controlling the electromagnet of the lower connector. The current control module controls the attraction between the two electromagnets by controlling the current flowing to the electromagnet, thereby aligning the connectors.

[0055] In this embodiment, the laser device is a laser irradiation device, including a laser transmitter and a laser receiver. The laser transmitter includes a laser, a voltage-stabilized constant current drive circuit and an intelligent control circuit connected in sequence, and is used to emit laser. The laser receiver includes a laser receiver, a laser signal demodulation and identification circuit and an intelligent control signal output circuit connected in sequence, and is used to receive the laser from the laser transmitter.

[0056] The laser transmitter is installed on the connector plug and is located on the surface of the plug; the laser receiver is installed on the connector socket and is located on the surface of the socket. Specifically, there are three lasers, including one laser installed in the center of the connector plug and two lasers distributed on the edge of the connector plug and symmetrical to the center; there are three laser receivers, including one laser receiver installed in the center of the connector socket and two laser receivers distributed on the edge of the connector socket and symmetrical to the center. There is a one-to-one correspondence between the three lasers and the three laser receivers. When the connector socket and the plug are aligned, the three laser receivers can receive the lasers emitted by the corresponding lasers.

[0057] Three lasers and three laser receivers can more accurately determine whether the connector is aligned, thereby achieving precise control. The three lasers are used to prevent the situation where the center position of the connector plug and socket remains relatively unchanged, but the connector is still not aligned, because at this time the center laser receiver can still receive the laser emitted by the laser, but the edge cannot receive it.

[0058] The signal monitoring device includes a signal receiving module, a signal processing module and a signal quality calculation module, and finally obtains a signal transmission quality value, compares the value with the signal transmission quality value during alignment, and determines whether the difference between the two exceeds a threshold.

[0059] The monitoring device of the present invention can determine whether the connector is aligned during the train turning process, and the judgment is made by combining laser data with signal transmission data, so that the judgment result is more accurate. When the connector is not aligned, the angle between the connector plug and the socket can be adjusted by controlling the electromagnet current to align them, thereby ensuring the safety of the train turning process and the quality of signal transmission.

[0060] This embodiment also provides a non-contact connector alignment monitoring method, such as Figure 2 As shown, the following steps are included: the first step is to determine whether the train is in the process of turning and determine the direction of the turn; the second step is to obtain data from the laser device and the signal monitoring device to obtain judgment data; the third step is to determine whether the non-contact connector is aligned according to the judgment data; the fourth step is to adjust the angle between the connector plug and the connector socket if the connector is not aligned to align the connector. The data of the laser device and the signal transmission quality are combined to jointly determine whether the connector is aligned, and the judgment result is more accurate. When the non-contact connector is not aligned during the train turning process, the non-contact connector can be adjusted to improve the safety of the train during the turning process and the signal transmission quality, thereby ensuring the safety of the train.

[0061] The following is a further description of the monitoring method of this application:

[0062] Step 1: Determine whether the train is in the process of turning and determine the direction of the turn.

[0063] The contactless connector is non-dynamically modeled, and the velocity vectors of each point on the contactless connector plug and socket are calculated through filtering trajectory; the increment of the velocity vector of the current point and the projection value of the velocity vector increment of the current point in the normal direction of the track surface of the previous point are calculated, and the turning direction of the single point is determined by the projection value; the turning directions calculated at multiple points on the contactless connector are statistically analyzed to determine the turning direction of the train. The turning direction can be compared with the magnetic force of the last electromagnet to determine whether the adjustment result is reliable. For example, when turning left, the centrifugal force on the left and right sides of the connector is different. In order to ensure alignment, the magnetic force of the electromagnet required on the left and right sides of the connector will also be different.

[0064] Step 2: Obtain data from the laser device and the signal monitoring device to obtain judgment data.

[0065] The data of the laser device is whether the three laser receivers all receive the laser emitted by the laser; the data of the signal monitoring device is whether the change in signal transmission quality exceeds a threshold.

[0066] Step 3: judging whether the contactless connector is aligned according to the judgment data.

[0067] There are four judgment methods:

[0068] 1. If the laser receiver can receive the laser emitted by the laser and the signal transmission quality changes within the threshold range, it means that the connectors are aligned.

[0069] 2. If the laser receiver can receive the laser emitted by the laser and the signal transmission quality change exceeds the threshold range, measure again. If the measurement result does not change, adjust the angle between the connector plug and the connector socket according to the signal transmission quality and measure again.

[0070] 3. If at least one of the laser transmitters cannot receive the laser light emitted by the laser, and the signal transmission quality changes beyond the threshold range, it means that the connector is not aligned.

[0071] 4. If at least one of the laser transmitters cannot receive the laser emitted by the laser, and the signal transmission quality changes within the threshold range, measure again. If the measurement result does not change, adjust the angle between the connector plug and the connector socket according to the laser device and measure again.

[0072] Step 4: If the connectors are not aligned, adjust the angle between the connector plug and the connector socket to align the connectors.

[0073] The magnetic force of the electromagnet is adjusted according to the judgment result. If the distance between the connector plug and the connector socket increases, the magnetic force of the electromagnet is increased; if the distance between the connector plug and the connector socket decreases, the magnetic force of the electromagnet is reduced. The adjustment can apply different magnetic forces to different electromagnets according to the specific judgment result and the turning direction of the train.

[0074] The adjustment can apply different magnetic forces to different electromagnets according to the specific judgment results and the turning direction of the train. Specifically, the electromagnets are evenly and spacedly distributed on the edges of the connector plug and the socket. If the distance between the left end of the connector plug and the socket is measured to be farther and the distance between the right end is closer, the current at the left end can be controlled to increase to increase the attraction of the electromagnet, the current at the left end can be controlled to increase to increase the attraction of the electromagnet, and the current at the right end can be controlled to increase to reduce the attraction of the electromagnet.

[0075] Embodiment 2:

[0076] In this embodiment, based on the first embodiment, the laser device does not adopt a laser irradiation device, but adopts a laser distance measuring device.

[0077] The laser distance measuring device includes:

[0078] A laser emitter, used for emitting laser, is installed in the center of the connector plug. In this embodiment, the laser emitted by the laser emitter is an outward-expanding laser, and the emitted laser can cover a large area of ​​the connector socket;

[0079] A laser receiver, used to receive the laser emitted by the laser transmitter, and used to be installed on the connector socket. This embodiment includes three laser receivers evenly and spaced apart on the central axis (left, middle, and right) of the connector socket;

[0080] A timing module is used to calculate the time taken for the laser transmitter to emit the laser and for the laser receiver to receive the laser;

[0081] The calculation module is used to calculate the distance between the connector plug and the socket according to the time of the timing module.

[0082] The laser light from the laser transmitter can also be guided to the laser receiver by a signal guiding device.

[0083] If the two connector terminals are aligned, the distances measured by the three laser receivers should be the same. If the two connector terminals are not aligned, the distances measured by the three laser receivers will deviate. When the deviation values ​​all exceed the error threshold, it indicates misalignment.

[0084] Specifically, in this embodiment, there are three ways to determine whether the contactless connectors are aligned:

[0085] 1. If the distance changes measured by two lasers between the contactless connector plug and the socket exceed the threshold, it means that the contactless connector plug and the socket are not aligned. According to the data of the laser device, the specific angle relationship between the contactless connector plug and the socket is determined.

[0086] For example, if the distance measured by the laser receiver on the left side of the socket is too small and the distance measured by the laser receiver on the right side is too large, the magnetic force of the electromagnet on the right side of the connector should be increased and the magnetic force of the electromagnet on the left side of the connector should be reduced to align the connectors.

[0087] 2. If the distance changes measured by the three laser receivers between the contactless connector plug and the socket do not exceed the threshold, and the signal transmission quality changes exceed the threshold range, measure again. If the measurement result does not change, adjust the angle between the contactless connector plug and the socket according to the signal transmission quality and measure again.

[0088] 3. If the distance change between the contactless connector plug and the socket and the signal transmission quality do not exceed the threshold, it means that the adjacent contactless connectors are aligned.

[0089] Embodiment three:

[0090] Based on the first embodiment, this embodiment adds a three-axis acceleration sensor for real-time measurement of the angle and speed of turning: the three-axis acceleration sensor is calibrated in the initial state; the acceleration vector data of the three-axis acceleration sensor is obtained, and the acceleration vector component in the direction of travel of the train and the lateral acceleration vector component perpendicular to the direction of travel of the train are calculated to obtain the travel speed vector of the train at the same time; the angle θi of the train turning within the time Δt is calculated based on the acceleration vector component, the lateral acceleration vector component and the travel speed vector.

[0091] At the same time, the control system controls the alignment device to correct the angle between the connector plug and the socket, and there is a reaction time. During the reaction time, because the train is still running, the angle between the contactor plug and the socket may still change. Therefore, this embodiment also designs a correction module to feedback and correct the current flowing to the electromagnet of the connector according to the train running speed and the current train angle.

[0092] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
