[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The core of the present invention is to provide a suspension sensor, a suspension sensor processing method and a maglev train system, which can improve the accuracy of gap measurement.

[0036] The suspension sensor provided by the present invention is applied to a maglev vehicle, and forms an eddy current effect by cooperating with the long stator 8 on the track, so as to measure relevant travel parameters when the vehicle is moving, for example, the measurement of the travel speed and the measurement of the gap between the suspension sensor and the track. The suspension sensor can convert the obtained speed signal or gap signal into an electrical signal, and provide it to the vehicle control system to control the travel speed, adjust the current of the suspension electromagnet in real time, ensure the stability of the gap between the track and the suspension electromagnet on the vehicle, so as to maintain a stable suspension state of the vehicle.

[0037] In the specific embodiment 1 of the suspension sensor provided by the present invention, as Figures 1 to 3 As shown, the suspension sensor includes a mounting box 1 , a sensor coil plate 2 , a support plate 3 , a pressing plate 7 , a positioning portion 4 and an electric control device 5 .

[0038] The installation box 1 is used to be connected to the maglev train and to carry other structures in the suspension sensor. The sensor coil plate 2 , the support plate 3 , the pressure plate 7 , the positioning part 4 and the electric control device 5 are all arranged in the installation box 1 .

[0039] The sensor coil plate 2 includes a coil substrate 21 and a gap measuring coil 22, and the gap measuring coil 22 is used to detect the gap between the suspension sensor and the track. The coil substrate 21 includes a main board 211 and two vertical boards 212, and the two vertical boards 212 are located at both ends of the main board 211 in the preset travel direction X. Among them, the preset travel direction X specifically corresponds to the travel direction of the vehicle, and the preset lateral direction Y is perpendicular to the preset travel direction X.

[0040] The gap measurement coil 22 can specifically detect the electromagnetic induction signal between the suspension electromagnet and the track to calculate the suspension gap. The gap measurement coil 22 at least spans a tooth structure 81 and a slot structure 82 of the long stator 8. To improve the accuracy of the measurement, it is necessary to reduce or avoid the tooth slot effect. The gap measurement coil 22 can be a circular coil, a rectangular coil or an 8-shaped coil.

[0041] like Figure 3 As shown, it is a schematic diagram of the coil substrate 21 in the unfolded state, and the main board 211 and the vertical board 212 are divided along the dotted line. Part of the structure of the gap measurement coil 22 is a first coil portion 221 arranged on the top surface of the main board 211. The parallel projection of the first coil portion 221 in the preset horizontal direction Y is a line segment with a certain length, which can specifically include coil segments such as straight line segments and arc segments extending along the preset travel direction X. The remaining part of the gap measurement coil 22 is a second coil portion 222 arranged on the vertical board 212. The second coil portion 222 is connected to the first coil portion 221 at two points on the docking line between the vertical board 212 and the main board 211. The parallel projection of the second coil portion 222 in the preset travel direction X is a line segment with a certain length. The second coil portion 222 can be a coil segment of a straight line segment, an arc segment, or a concave segment.

[0042] On the long stator 8 of the track, there are tooth structures 81 and slot structures 82 arranged in sequence in an alternating manner along the preset travel direction X. The portion of the gap measurement coil 22 extending perpendicular to the preset travel direction X passes through the tooth structure 81 and the slot structure 82 in sequence, and is greatly affected by the tooth and slot fluctuations of the long stator 8. In the suspension sensor of the present application, the gap measurement coil 22 is distributed on the main board 211 and the vertical plate 212, and the portion on the main board 211 faces the long stator 8. The portion of the gap measurement coil 22 on the main board 211 is used to cooperate with the long stator to perform gap measurement, and the second coil portion 222 located on the vertical plate 212 can avoid the long stator 8. The second coil portion 222 has a certain projection length in the preset travel direction X, which can eliminate the influence of the tooth and slot fluctuations on this part of the coil portion during the gap measurement, thereby improving the accuracy of the gap measurement result.

[0043] Further, the two ends of the coil substrate 21 in the preset travel direction X are bent downward to form the vertical plates 212 respectively, and the remaining part of the coil substrate 21 forms the main plate 211. The coil substrate 21 is formed by direct bending, and the structure is simple and easy to process. Accordingly, as the coil substrate 21 is formed, the first coil part 221 and the second coil part 222 of the gap measurement coil 22 on the coil substrate 21 are synchronously distributed on the main plate 211 and the vertical plate 212, as shown in FIG. Figure 2 In the embodiment, the left and right portions of the gap measurement coil 22 extending out of the tooth structure 81 and the slot structure 82 respectively form the second coil portion 222; Figure 3 In the figure, the coil substrate 21 is bent with the dotted line as the docking line to form a main board 211 and a vertical board 212, respectively. The middle part of the gap measurement coil 22 is a first coil part 221, and the two sides are respectively second coil parts 222. Of course, in other embodiments, the main board 211 and the vertical board 212 can also be formed by splicing.

[0044] The butt joint line between the main board 211 and the support board 3 may be a straight line, and the two butt joint lines may be arranged in parallel, and may be perpendicular to the preset travel direction X. In addition, the vertical board 212 is perpendicular to the preset travel direction X to ensure that the second coil portion 222 avoids the long stator 8 and facilitates the control of the bending angle.

[0045] In the installation box 1, in order to improve the stability of the sensor coil plate 2 installed in the installation box 1, as shown in FIG. Figure 1 As shown, the support plate 3 is arranged below the main board 211, and the vertical plate 212 is fixed between the side of the support plate 3 and the side of the installation box 1. Specifically, the support plate 3 is made of a foam board. Specifically, the height of the side of the support plate 3 that is in contact with the vertical plate 212 is not less than the height of the vertical plate 212, so as to ensure the fit between the support plate 3 and the main board 212, and to prevent the installation box 1 from propping up the vertical plate 212 and causing the main board 212 to float on the support plate 3; or, the bottom end of the vertical plate 212 can be located below the support plate 3, and extend into and plug into a slot on the ground of the installation box 1, so as to improve the positioning capability of the sensor coil plate 2 through the slot.

[0046] In addition, the sensor coil plate 2 is adhesively fixed to the mounting box 1 and / or the support plate 3 to improve the connection strength of the sensor coil plate 2. Specifically, during the assembly process, the bottom surface of the sensor coil plate 2 or the top surface of the support plate 3 can be fully coated with adhesive, and after the sensor coil plate 2 is bent into shape and placed in the mounting box 1, adhesive fixation is simultaneously achieved. Of course, in other embodiments, the sensor coil plate 2 and the mounting box 1 or the support plate 3 can also be fixed by bolts for reinforcement.

[0047] In addition, if Figure 1As shown, the main board 211 includes an arc-shaped plate with a downward convex middle portion in the preset travel direction X. A pressing plate 7 is provided in the concave portion of the top surface of the arc-shaped plate to press down the main board 211. The pressing plate 7 is specifically a resin plate. Specifically, to ensure the pressing effect, the pressing plate 7 is a strip plate extending along the preset transverse direction Y, and the length in this direction can be the same as the length of the main board 211, so as to be able to press down at various positions in this direction. Among them, in the preset travel direction X, the straight-line distance between the main board 211 and the docking line of the two vertical boards 212 is the sum of the lengths of a tooth structure 81 and a groove structure 82. At the same time, as Figure 1 As shown, the top surface of the support plate 3 is an arc-shaped surface that fits with the bottom surface of the arc-shaped plate.

[0048] Among them, after the pressure plate 7 is pressed on the arc-shaped depression on the top surface of the sensor coil plate 2, in order to further reduce the influence of the pressure plate 7 on the appearance of the mounting box 1, the top surface of the pressure plate 7 does not protrude above the highest point of the sensor coil plate 2, so that the groove of the arc plate can fully accommodate the pressure plate 7.

[0049] Among them, Figure 1 As shown, the main board 211 of the sensor coil board 2 may also have flat plates at both ends in the preset direction of travel, and the two flat plates are coplanarly arranged and respectively located on both sides of the arc-shaped plate, and the two flat plates are arranged perpendicular to the vertical plate 212. Accordingly, the top surface of the support plate 3 is also correspondingly arranged as a middle arc-shaped surface and flat surfaces at both ends, so as to fit with different parts of the bottom surface of the main board 211 of the sensor coil board 2. With the help of the flat matching parts, the positioning effect is improved to prevent the sensor coil board 2 from sliding on the arc-shaped surface of the support plate 3. Specifically, the center line of the arc-shaped plate may be parallel to the preset horizontal direction Y.

[0050] Based on the cooperation of the pressing plate 7, the supporting plate 3 and the sensor coil plate 2, the reliability of fixing the sensor coil plate 2 can be further improved. At the same time, since the middle of the top surface of the arc plate is concave, it can accommodate the pressing plate 7, and the space in the installation box 1 can be more fully utilized. Moreover, the fitting cooperation between the arc plate and the supporting plate 3 also has a positioning effect. Of course, in other embodiments, the main board 211 can also be a flat plate structure.

[0051] Furthermore, if Figure 1 As shown, the installation box 1 includes a first box body 11 and a second box body 12 fixed below one end of the first box body 11 in a preset horizontal direction Y and connected to the first box body 11. At this time, the installation box 1 is an L-shaped box body. The installation box 1 is fixed to the maglev train through the second box body 12.

[0052] The sensor coil plate 2, the support plate 3 and the pressure plate 7 are arranged in the first box body 11, and the electric control device 5 is arranged in the second box body 12. The main board 211 is provided with an electrical connector 24 at one end in the preset horizontal direction Y, which can be a wire or a circuit board. The electrical connector 24 is electrically connected to the electric control device 5 through the top opening on the second box body 12, and the electric control device 5 can be connected to other electrical components through the bottom opening of the second box body 12 for communication.

[0053] Part of the structure of the support plate 3 is a connecting portion 31, which is fixed on the top of the second box body 12, and can be fixed by screws. The two connecting portions 31 are located on both sides of the electrical connector 24 in the preset travel direction X. The electrical connector 24 is also provided with a positioning portion 4 to cover the top of the electrical connector 24 to improve the reliability of the positioning of the electrical connector 24.

[0054] Specifically, Figure 1 As shown, the first box body 11 has an upwardly opening notch, which is separated from the upward opening of the second box body 12 by a partition. The positioning portion 4 includes a first positioning block 41 and a second positioning block 42, which are arranged in sequence along the preset horizontal direction Y, wherein the electrical connector 24 may include a first connector 241 extending upwardly obliquely and a second connector 242 located just above the opening of the second box body 12, the transition block 6 is located below the first connector 241, specifically, it can be located in the first box body 11, and is arranged in affixed to the partition, the first positioning block 41 is located below the first connector 241, and the top surface of the transition block 6 and the bottom surface of the first positioning block 41 are inclined surfaces that fit the first connector 241, and the second positioning block 42 is installed above the second connector 242, so as to realize the respective positioning of the parts of different shapes on the electrical connector 24 in different regions, improve the reliability of the positioning and fixing of the electrical connector 24, and thus realize the comprehensive fixing of the sensor coil plate 2.

[0055] Specifically, the positioning portion 4 and the transition block 6 are foam boards.

[0056] Specifically, a sealing layer, such as a resin layer, may be further provided above the pressing plate 7 to seal the top opening of the mounting box 1 .

[0057] Furthermore, two gap measuring coils 22 are sequentially arranged on the coil substrate 21 along the preset horizontal direction Y. The two gap measuring coils 22 cooperate with each other to effectively improve the accuracy of the gap measurement result. In addition, when the measurement results of the two gap measuring coils 22 differ greatly, it may be that at least one gap measuring coil 22 is damaged, which can be used to provide a maintenance prompt signal.

[0058] Furthermore, the sensor coil plate 2 also includes a speed measuring coil 23 to measure the travel speed. Specifically, the principle of the speed measuring coil is based on the principle of electromagnetic induction. When a conductor moves in a magnetic field, an electromotive force is induced in the conductor. By measuring the magnitude and rate of change of the induced electromotive force, the movement speed of the conductor can be calculated. Figure 2 As shown, two speed measuring coils 23 are sequentially arranged on the top surface of the main board 211 along the preset travel direction X. The speed measuring coils 23 calculate the speed by counting the number of teeth and slots, and each speed measuring coil 23 alternately passes through the tooth structure 81 and the slot structure 82 in sequence, and the tooth slot effect needs to be applied. Specifically, the arrangement of the speed measuring coils 23 on the coil substrate 21 is perpendicular to the preset travel direction X, specifically, the coils extending along the preset horizontal direction Y.

[0059] Among them, in the preset travel direction X: the width of the gap measurement coil 22 relative to the tooth slot is: the width after the two sides of the coil substrate 21 are folded (that is, the linear dimension of the main board 211) is equal to the width of one tooth structure 81 + one slot structure 82; the speed coil width is smaller than the width of the tooth structure 81 or the slot structure 82, and in the preset travel direction X: the spacing of the center lines of the two speed measurement coils 23 extending along the preset horizontal direction Y is equal to the spacing of the center lines of the adjacent tooth structures 81 and slot structures 82 extending along the preset horizontal direction Y.

[0060] The suspension sensor provided in this embodiment uses a sensor coil plate 2, which has two gap measurement coils 22. Part of the coils of the gap measurement coil 22 are located on a vertical plate 212 that avoids the long stator 8 to overcome the problem of abnormal gap collection caused by tooth slot fluctuations and improve the stability of gap measurement. Two speed measurement coils 23 are provided to improve the accuracy of speed measurement, thereby realizing accurate collection of gap and speed signals, thereby achieving the effect of stable suspension of the train.

[0061] The present invention also provides a method for processing a suspension sensor, which is used for processing the suspension sensor, comprising:

[0062] S1: bend the two ends of the sensor coil plate 2 in the preset moving direction X, so that the two ends of the coil substrate 21 of the sensor coil plate 2 form upright plates 212 respectively, and the remaining part is the main plate 211 .

[0063] Among them, after the coil substrate 21 is bent, in the sensor coil plate 2, a gap measuring coil 22 is provided on the sensor coil plate 2, and a partial structure of the gap measuring coil 22 is a first coil portion 221 provided on the top surface of the main board 211, and the remaining part is a second coil portion 222 provided on the vertical plate 212, and the second coil portion 222 is connected to the first coil portion 221 at two points on the docking line between the vertical plate 212 and the main board 211.

[0064] Among them, in the processing operation of the coil substrate 21, the gap measurement coil 22 and the speed measurement coil 23 can be processed on the flat coil substrate 21 first, and then the coil substrate 21 can be bent. When bending, it can be achieved with the help of a bending machine. Specifically, the coil substrate 21 is placed on the mold of the bending machine for fixing to ensure that the coil substrate 21 does not move during the processing. The coil substrate 21 is made to reach the designed angle through hydraulic or mechanical pressure to form an arc plate and a vertical plate 212. In order to facilitate the demoulding of the coil substrate 21, when the vertical plate 212 is formed, the coil substrate 21 can be bent 90° or less than 90° relative to its original flat part.

[0065] In the coil substrate 21, the position of the docking line between the main board 211 and the vertical board 212 can be determined by the distribution adaptability of the gap measurement coil 22. Figure 3 As shown, the second coil portion 222 can extend parallel to the preset horizontal direction Y, and the butt joint line is arranged in close contact with the edge of the second coil portion 222, and all the second coil portions 222 are ensured to be located on the vertical plate 212, thereby ensuring that the coils extending parallel to the preset horizontal direction Y are more located on the vertical plate 212, reducing the influence of the tooth groove fluctuation. In addition, after the two vertical plates 212 are bent and formed, their heights can be specifically set to be the same.

[0066] S2: Place the sensor coil board 2 in the installation box 1 , and place the main board 211 above the support board 3 in the installation box 1 , and insert the vertical board 212 between the side of the support board 3 and the side of the installation box 1 .

[0067] The support plate 3 and the sensor coil plate 2 , specifically, the main board 211 and the support plate 3 , can be bonded and fixed; in addition, the vertical plate 211 and the support plate 3 and the installation box 1 can also be bonded and fixed.

[0068] The installation box 1 is used to be connected to the maglev train.

[0069] In the processing method of this embodiment, when the circuit board with the gap measuring coil 22 is installed in the installation box 1, the two sides are bent and then placed. This can avoid the influence of the tooth slot effect in the gap measurement, reduce the large fluctuation of the waveform measured by the gap due to the existence of the tooth slot, and effectively improve the stability of the gap measurement.

[0070] In addition to the above-mentioned suspension sensor and the processing method of the suspension sensor, the present invention also provides a maglev train system, which includes a maglev vehicle and a track. The maglev vehicle is provided with a suspension sensor. The suspension sensor can specifically be the suspension sensor provided in any of the above embodiments. The beneficial effects can be referred to the above embodiments accordingly. Specifically, the signal acquisition precision and accuracy can be improved, the influence of tooth groove fluctuation can be reduced, and the gap acquisition abnormality and other problems existing in the operation of the suspension guide sensor of the high-speed maglev train are solved.

[0071] Among them, in the maglev train system, a long stator 8 is provided on the track, and the bottom surface of the long stator 8 includes a tooth structure 81 and a slot structure 82 which are sequentially staggered along the preset travel direction X. A suspension electromagnet is also provided on the maglev vehicle, and the suspension electromagnet on the maglev vehicle cooperates with the track to realize the suspension and travel of the maglev vehicle on the track. In addition, when the suspension sensor performs gap control, it can transmit the detected gap signal to the corresponding control device, and the control device adjusts the excitation current of the suspension electromagnet so that the gap value between the track and the suspension electromagnet is kept below the set gap. In addition, when the driving speed changes, the set gap may also be switched back to adaptive change.
