[0059] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. However, it is obvious that one or more embodiments may be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concepts of the present disclosure.

[0060] The terms used herein are for describing specific embodiments only and are not intended to limit the present disclosure.

[0063] In the embodiments of the present disclosure, in aspects such as the collection, update, analysis, processing, use, transmission, provision, disclosure, storage, etc. of the data involved (for example, including but not limited to user personal information), they all comply with the provisions of relevant laws and regulations, are used for legal purposes, and do not violate public order and good customs. In particular, necessary measures are taken for user personal information to prevent illegal access to user personal information data and to maintain the security of user personal information, network security, and national security.

[0064] In the embodiments of the present disclosure, the authorization or consent of the user is obtained before obtaining or collecting user personal information.

[0065] In the related art, the direction of the motor steering of a train is usually determined manually by a first-line train debugging staff by feeling the rotation direction of the coupling or by using a special test tooling. This is not intelligent enough and has the disadvantages of wasting manpower and material resources.

[0066] In view of this, the embodiments of the present disclosure provide a method for identifying the steering of a traction motor of a train, including starting the traction motor in response to receiving a detection instruction for detecting the traction motor of the train; sensing the rotation of the gear of the traction motor through an induction sensor to obtain a first induction signal and a second induction signal, wherein the induction sensor includes a first sub-induction element and a second sub-induction element, and the first sub-induction element and the second sub-induction element are respectively arranged at different positions along the clockwise rotation direction of the gear of the traction motor; determining the motor steering of the traction motor according to the phase relationship between the first induction signal and the second induction signal; and determining a detection result according to the motor steering and the driving direction information of the train, wherein the detection result characterizes whether the steering of the traction motor is correct.

[0067] Figure 1 Schematically shows an application scenario diagram of a traction motor steering recognition method, device and train according to an embodiment of the present disclosure.

[0068] As Figure 1 shown, the application scenario 100 according to this embodiment may include a first train 110 and a second train 120. The first train 110 and the second train 120 may include a device for recognizing the steering of the traction motor of the train, and by responding to a detection instruction for detecting the traction motor of the train, start the traction motor; sense the rotation of the gear of the traction motor through an induction sensor to obtain a first induction signal and a second induction signal, wherein the induction sensor includes a first sub-induction element and a second sub-induction element, and the first sub-induction element and the second sub-induction element are respectively arranged at different positions along the clockwise rotation direction of the gear of the traction motor; determine the motor steering of the traction motor according to the phase relationship between the first induction signal and the second induction signal; determine the detection result according to the motor steering and the driving direction information of the train, wherein the detection result characterizes whether the steering of the traction motor is correct.

[0069] Figure 2 Schematically shows a system connection diagram of a train according to an embodiment of the present disclosure.

[0070] As Figure 2 shown, multiple network units may be arranged in the train, and the multiple network units may communicate with each other. For the convenience of description, taking the load device as an air conditioner as an example, the network unit is connected to the auxiliary converter and the air conditioner controller through a Multifunction Vehicle Bus (MVB) or Ethernet (ETH). n traction converters 1, 2, 3... n may be arranged in the train, and each traction converter controls 4 traction motors (axles 1, 2, 3, and 4 in the figure) of two power bogies. A Hall-type two-channel speed sensor may be installed at the non-driving end of each traction motor, and the two Hall induction elements of the sensor are placed in the magnetic field of the magnet. When the gear of the traction motor rotates, the magnetic flux passing through the Hall induction element changes.

[0071] Figure 3 Schematically shows a flowchart of a traction motor steering recognition method of a train according to an embodiment of the present disclosure.

[0072] As Figure 3 shown, this method includes operations S310 to S340.

[0073] In operation S310, in response to receiving a detection instruction for detecting the traction motor of the train, start the traction motor.

[0074] In operation S320, the rotation of the gear of the traction motor is sensed by a sensing sensor to obtain a first sensing signal and a second sensing signal. The sensing sensor includes a first sub-sensing element and a second sub-sensing element, and the first sub-sensing element and the second sub-sensing element are respectively arranged at different positions along the clockwise rotation direction of the gear of the traction motor.

[0075] In operation S330, according to the phase relationship between the first sensing signal and the second sensing signal, the rotation direction of the traction motor is determined.

[0076] In operation S340, according to the rotation direction of the motor and the driving direction information of the train, a detection result is determined, where the detection result characterizes whether the rotation direction of the traction motor is correct.

[0077] According to an embodiment of the present disclosure, the detection instruction can be issued by a terminal device, and after the sensing sensor is set up, the detection instruction can be issued.

[0078] According to an embodiment of the present disclosure, the first sub-sensing element and the second sub-sensing element are respectively arranged at different positions along the clockwise rotation direction of the gear of the traction motor. Therefore, when the gear of the traction motor rotates, the first sensing signal and the second sensing signal obtained can be signals with different phases, and thus the rotation direction of the traction motor can be determined according to the phase relationship between the first sensing signal and the second sensing signal.

[0079] According to an embodiment of the present disclosure, the sensing sensor can be a Hall-type two-channel speed sensor.

[0080] According to an embodiment of the present disclosure, the driving direction information of the train can be obtained from the train, and the driving direction information of the train can be obtained by detecting the direction handle of the train.

[0081] According to an embodiment of the present disclosure, by combining the rotation direction of the traction motor with the driving direction information of the train, it can be confirmed whether the rotation direction of the traction motor matches the driving direction of the train. When the two match, it can be determined that the detection result is that the rotation direction of the traction motor is correct; when the two do not match, it can be determined that the detection result is that the rotation direction of the traction motor is incorrect.

[0082] According to an embodiment of the present disclosure, by providing an induction sensor in the traction motor, a first induction signal and a second induction signal can be automatically obtained when the gear of the traction motor rotates. The first sub-induction element and the second sub-induction element of the induction sensor are arranged at different positions, so that there is a phase difference between the first induction signal and the second induction signal. According to the phase relationship between the first induction signal and the second induction signal, the rotation direction of the traction motor can be determined. Furthermore, by combining with the driving direction information of the train, the detection result of the steering motor can be determined, achieving full-automatic detection without manual detection, improving the efficiency of detecting the train traction motor, and requiring fewer devices, thus reducing the cost of detecting the train traction motor.

[0083] Figure 4 Schematically shows a schematic diagram of the induction principle of the Hall induction element in the traction motor according to an embodiment of the present disclosure.

[0084] As Figure 4 shown in a of [reference], when the top surface of the tooth of the gear of the traction motor faces the Hall induction element, the magnetic field lines passing through the Hall induction element are the most concentrated and the magnetic flux is the largest; as Figure 4 shown in b of [reference], when the bottom surface of the tooth of the gear of the traction motor faces the Hall induction element, the magnetic field lines passing through the Hall induction element are the most dispersed and the magnetic flux is the smallest. When the traction motor rotates, the top surface and the bottom surface of the tooth of the gear alternately pass through the Hall induction element, and the generated magnetic flux also changes alternately. According to the alternating change of the magnetic flux generated by the gear in the Hall induction element, the induced voltage of the Hall induction element also changes alternately, so that an induction signal can be obtained according to the change of the induced voltage.

[0085] Specifically, in the embodiment of the present disclosure, the first sub-induction element includes a first Hall induction element, and the second sub-induction element includes a second Hall induction element.

[0086] Among them, by the induction sensor to sense the rotation of the gear of the traction motor to obtain a first induction signal and a second induction signal, including: sensing the first magnetic flux generated when the gear of the traction motor rotates through the first Hall induction element to obtain the first induction signal; sensing the second magnetic flux generated when the gear of the traction motor rotates through the second Hall induction element to obtain the second induction signal.

[0087] According to an embodiment of the present disclosure, when the gear of the traction motor rotates, magnetic flux is generated in the first Hall induction element and the second Hall induction element. The first induction signal is generated according to the first magnetic flux generated by the first Hall induction element, and the second induction signal is generated according to the second magnetic flux generated by the second Hall induction element. It can be known from Figure 4 this that the first magnetic flux and the second magnetic flux are changing. Therefore, the first induction signal and the second induction signal also change according to the top surface and the bottom surface of the gear tooth.

[0088] According to an embodiment of the present disclosure, the positions where the first sub-inductive element and the second sub-inductive element are arranged can cause a certain phase difference between the inductive signals generated by the two.

[0089] According to an embodiment of the present disclosure, by using the first Hall inductive element to sense the first magnetic flux generated when the gear of the traction motor rotates, a first inductive signal is obtained, including: using the first Hall inductive element to sense the first magnetic flux generated when the gear of the traction motor rotates, generating a first inductive voltage; and obtaining the first inductive signal according to the first inductive voltage.

[0090] By using the second Hall inductive element to sense the second magnetic flux generated when the gear of the traction motor rotates, a second inductive signal is obtained, including: using the second Hall inductive element to sense the second magnetic flux generated when the gear of the traction motor rotates, generating a second inductive voltage; and obtaining the second inductive signal according to the second inductive voltage.

[0091] According to an embodiment of the present disclosure, when the traction motor rotates, the top surface and the bottom surface of the gear alternately pass through the first Hall inductive element and the second Hall inductive element, and the first magnetic flux and the second magnetic flux generated also change alternately. According to the alternating change of the first magnetic flux and the second magnetic flux, the first inductive voltage generated by the first Hall inductive element and the second inductive voltage of the second Hall inductive element also change alternately. Thus, the first inductive signal and the second inductive signal can be obtained according to the change of the first inductive voltage and the change of the second inductive voltage. The first inductive signal can characterize the rotation of the steering motor at the position relative to the first Hall inductive element, and the second inductive signal can characterize the rotation of the steering motor at the position relative to the second Hall inductive element.

[0092] According to an embodiment of the present disclosure, by arranging a plurality of Hall inductive elements, first inductive signals and second inductive signals with different phases can be obtained, so that the steering of the steering motor can be accurately judged.

[0093] According to an embodiment of the present disclosure, according to the motor steering and the train running direction information, a detection result is determined, including: when it is determined that the steering of the traction motor represented by the motor steering is consistent with the train running direction, it is determined that the detection result represents that the steering of the traction motor is correct; when it is determined that the steering of the traction motor represented by the motor steering is inconsistent with the train running direction, it is determined that the detection result represents that the steering of the traction motor is incorrect.

[0094] Figure 5 Schematically shows a schematic diagram of the first inductive signal and the second inductive signal when the traction motor rotates clockwise and counterclockwise according to an embodiment of the present disclosure.

[0095] AsFigure 5 As shown in a, the preset phase may be 90°, and in Figure 5 it may be represented as the rising edge a1 of the first induction signal S1 leading the rising edge a2 of the second induction signal S2. Among them, the rising edge a1 of the first induction signal S1 and the rising edge a2 of the second induction signal S2 may detect the same position of the traction motor.

[0096] As Figure 5 shown in b, the rising edge b2 of the second induction signal S2 leads the rising edge b1 of the first induction signal S1, and the rising edge b2 of the second induction signal S2 and the rising edge b1 of the first induction signal S1 may detect the same position of the traction motor.

[0097] Specifically, in the embodiments of the present disclosure, determining the motor rotation direction of the traction motor according to the phase relationship between the first induction signal and the second induction signal may include: when it is determined that the phase difference between the first induction signal and the second induction signal indicates that the first induction signal is before the second induction signal, determining that the motor rotation direction of the traction motor is clockwise; when it is determined that the phase difference between the first induction signal and the second induction signal indicates that the first induction signal is after the second induction signal, determining that the motor rotation direction of the traction motor is counterclockwise.

[0098] According to the embodiments of the present disclosure, the first induction signal being before the second induction signal may be that the signal for inducing the traction motor in the first induction signal is ahead of the signal for inducing the same position of the traction motor in the second induction signal on the time axis. The first induction signal being before the second induction signal may be the phase relationship as shown in Figure 5 a, where the rising edge a1 of the first induction signal leads the rising edge a2 of the second induction signal. In this case, the motor rotation direction of the traction motor may be determined to be clockwise.

[0099] According to the embodiments of the present disclosure, the first induction signal being after the second induction signal may be that the signal for inducing the traction motor in the second induction signal is ahead of the signal for inducing the same position of the traction motor in the first induction signal on the time axis. The first induction signal being after the second induction signal may be the phase relationship as shown in Figure 5 b, where the rising edge b2 of the second induction signal leads the rising edge b1 of the first induction signal. In this case, the motor rotation direction of the traction motor may be determined to be counterclockwise.

[0100] According to the embodiments of the present disclosure, by comparing the phase relationship between the first induction signal and the second induction signal, the motor rotation direction can be determined without manual confirmation, improving the intelligence of the traction motor rotation direction recognition.

[0101] According to an embodiment of the present disclosure, when the motor rotation direction of the traction motor is clockwise, it is determined that the rotation direction of the traction motor indicates that the train is moving forward; when the motor of the traction motor is counterclockwise, it is determined that the rotation direction of the traction motor indicates that the train is moving backward.

[0102] According to an embodiment of the present disclosure, the above method may further include: when it is determined that the motor rotation direction of the traction motor is clockwise and the driving direction information indicates that the train is moving forward, it is determined that the rotation direction of the traction motor represented by the motor rotation direction is consistent with the driving direction of the train; when it is determined that the motor rotation direction of the traction motor is clockwise and the driving direction information indicates that the train is moving backward, it is determined that the rotation direction of the traction motor represented by the motor rotation direction is inconsistent with the driving direction of the train; when it is determined that the motor rotation direction of the traction motor is counterclockwise and the driving direction information indicates that the train is moving forward, it is determined that the rotation direction of the traction motor represented by the motor rotation direction is inconsistent with the driving direction of the train; when it is determined that the motor rotation direction of the traction motor is counterclockwise and the driving direction information indicates that the train is moving backward, it is determined that the rotation direction of the traction motor represented by the motor rotation direction is consistent with the driving direction of the train.

[0103] According to an embodiment of the present disclosure, the rotation direction of the traction motor can be determined by the phase difference between the first induction signal and the second induction signal, and by comparing the rotation direction of the traction motor with the direction of the direction handle of the train, it can be determined whether the phase sequence wiring of the traction motor is correct. As shown in Table 1.

[0106] According to an embodiment of the present disclosure, the above method may further include: when the detection result indicates that the rotation direction of the traction motor is incorrect, generating a prompt message indicating that the detection result is that the rotation direction of the traction motor is incorrect; and displaying the prompt message through a display unit.

[0107] According to an embodiment of the present disclosure, the display unit may be the display screen of the terminal device that issues the detection instruction. The prompt message may include the information of "the rotation direction of the traction motor is incorrect", so that the rotation direction of the traction motor can be adjusted in time.

[0108] Figure 6 Schematically shows a flowchart of a method for identifying the rotation direction of a traction motor of a train according to another embodiment of the disclosure.

[0109] As Figure 6 shown, the method includes operation S610 to operation S680.

[0110] In operation S610, in response to receiving a detection instruction for detecting the traction motor of the train, the traction motor is started.

[0111] In operation S620, the gear rotation of the traction motor is sensed by an induction sensor to obtain a first induction signal and a second induction signal.

[0112] In operation S630, it is determined whether the phase difference between the first induction signal and the second induction signal indicates that the first induction signal is before the second induction signal. If so, operation S640 is executed; if not, operation S660 is executed.

[0113] In operation S640, it is determined whether the travel direction information indicates that the train is traveling forward. If so, operation S650 is executed; if not, operation S670 is executed.

[0114] In operation S650, it is determined that the detection result indicates that the steering of the traction motor is correct.

[0116] In operation S670, it is determined that the detection result indicates that the steering of the traction motor is incorrect.

[0117] In operation S680, a prompt message indicating that the detection result is that the steering of the traction motor is incorrect is generated and the prompt message is displayed through a display unit.

[0118] According to the embodiments of the present disclosure, the descriptions of operations S610 to S680 may refer to other embodiments of the present disclosure and will not be elaborated herein.

[0119] According to the embodiments of the present disclosure, the method for identifying the steering of the traction motor of the train in the embodiments of the present disclosure can be implemented by a software algorithm, which can quickly and accurately identify and judge the steering direction of the traction motor or the coupling, and at the same time, there is no need to install any detection equipment near the traction motor of the bogie under the vehicle, shortening the test cycle for judging the steering of the traction motor, realizing the automatic detection of the steering judgment of the traction motor of the EMU, and at the same time being able to reduce the detection cost.
