Abstract
Description
Technical Field
[0001] This utility model relates to the field of maglev train suspension control technology, and in particular to a suspension sensor for medium and low speed maglev vehicles. Background Technology
[0002] The suspension sensor housing of medium- and low-speed maglev vehicles contains two circuit boards, one for digital signal processing and the other for analog signal processing. One circuit board, located at the bottom of the suspension sensor housing, is used for coil excitation and gap signal processing, while the other circuit board, located at the top of the suspension sensor housing, is used for digital acquisition and linear compensation of gap and acceleration signals. Furthermore, the power supply and control chips of the two circuit boards suffer from redundant circuit design and complex layout, making them prone to circuit failures.
[0003] The suspension sensor not only lacks fault diagnosis capabilities, but its fault diagnosis function is also implemented by the suspension controller. Since the suspension controller and suspension sensor are separate components, it's ultimately impossible to pinpoint whether the gap and acceleration faults are caused by the transmission cable of the suspension controller or the suspension sensor. Therefore, the diagnostic results may suffer from misdiagnosis, missed diagnosis, and difficulty in fault location.
[0004] Therefore, it is urgent to solve the problem that the suspension sensor does not have fault diagnosis function. Utility Model Content

[0065] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0066] In this invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0067] As the background technology shows, existing suspension sensors lack fault diagnosis capabilities, leading to the suspension controller diagnosing suspension sensor faults. However, since the suspension controller and suspension sensor are separate components, when the suspension controller diagnoses a fault, it cannot pinpoint whether the fault originates in the suspension controller itself or from the transmission cable of the suspension sensor, resulting in gap or acceleration faults. Consequently, the diagnostic results may suffer from misdiagnosis, missed diagnosis, and difficulty in fault location.
[0068] Therefore, this utility model embodiment provides a suspension sensor for medium- and low-speed maglev vehicles, which includes a suspension sensor body. The suspension sensor body consists of a data circuit board and a control circuit board. The control circuit board enables the suspension sensor to have fault diagnosis capabilities, thereby solving problems such as misdiagnosis, missed diagnosis, and difficulty in fault location.
[0069] Therefore see Figure 1 This diagram illustrates a first structural schematic of a levitation sensor for a medium-low speed maglev vehicle according to an embodiment of the present invention. The levitation sensor includes:
[0070] The suspension sensor housing 6 is composed of a fixing part 101 and a mounting part 102, and the mounting part 102 is provided with at least a first mounting groove and a second mounting groove.
[0071] Optionally, in this embodiment of the utility model, the mounting part 102 is not limited to having two mounting slots, but may also have N mounting slots, which can be configured according to requirements.
[0072] It should be noted that a passage is provided between the first mounting slot and the second mounting slot.
[0073] The suspension sensor body 103 is installed in the first mounting slot.
[0074] A suspension sensor cover plate 1 is attached to the suspension sensor body 103 and connected to the first mounting slot.
[0075] The gap measuring probe 7 is installed in the second mounting slot and connected to the suspension sensor body 103. The gap measuring probe 7 is sealed in the second mounting slot by potting with anti-corrosion material.
[0076] It should be noted that the suspension sensor body 103 is connected to the gap measuring probe 7 and can form an excitation circuit with the gap measuring probe 7. Furthermore, the suspension sensor body 103 can also receive the impedance parameter changes measured by the gap measuring probe 7.
[0077] In some embodiments, the anti-corrosion material is epoxy resin, which has properties such as high strength, good hardness, chemical resistance, adhesion, heat resistance, and corrosion resistance.
[0078] The external suspension sensor connector 5 is located at the bottom of the mounting section 102 and is connected to the suspension sensor body 103.
[0079] It should be noted that the suspension sensor body 103 is connected to the external suspension sensor connector 5. The gap signal and acceleration information are transmitted to the suspension controller through the external suspension sensor connector 5. The existing suspension controller's fault diagnosis function based on the gap signal and acceleration signal is retained. The suspension sensor also receives the DC24V voltage provided by the suspension controller through the external suspension sensor connector 5.
[0080] An accelerometer 4 is installed inside the suspension sensor housing 6 and connected to the suspension sensor body 103.
[0081] Optionally, the suspension sensor body 103 is connected to the accelerometer 4 disposed inside the suspension sensor housing 6 through the opening of the first mounting slot.
[0082] Specifically, the accelerometer 4 is used to detect the acceleration value of the suspension sensor, that is, the acceleration signal, and send it to the suspension sensor body 103 so that the suspension sensor body 103 can perform fault diagnosis based on the acceleration signal.
[0083] The suspension sensor body 103 consists of a data circuit board 2 and a control circuit board 3.
[0084] In some embodiments, the data circuit board 2 and the control circuit board 3 employ chips with higher integration and better performance, which can optimize the circuitry of the digital signal processing circuit board and the analog signal processing circuit board in the suspension sensor. The integration of the functions of the two circuit boards can reduce the power supply circuit, control chip and its peripheral circuits.
[0085] The data circuit board 2 is mounted on the suspension sensor cover plate 1 via the isolation column 9. The input end of the data circuit board 2 is connected to the output end of the control circuit board 3. The data circuit board 2 is equipped with a data storage circuit and a wireless transmission circuit.
[0086] In some embodiments, the data circuit board 2 is mounted on the suspension sensor cover plate 1 via four isolation pillars 9, wherein the data circuit board 2 employs a dedicated flat wireless communication antenna, which can increase the wireless transmission signal in the suspension sensor.
[0087] The first input terminal of the control circuit board 3 is connected to the gap measuring probe 7, and the second input terminal of the control circuit board 3 is connected to the output terminal of the external connector 5 of the suspension sensor. The control circuit board 3 is equipped with a control circuit.
[0088] Understandably, the first input terminal of the control circuit board 3 is connected to the gap measuring probe 7 through the opening of the second mounting slot. The second input terminal of the control circuit board 3 is connected to the output terminal of the external connector 5 of the suspension sensor through the opening at the bottom of the mounting part 102.
[0089] In the suspension sensor disclosed in this utility model, the functions of the digital signal processing circuit board and the analog signal processing circuit board are integrated and optimized to form a suspension sensor body composed of a control circuit board and a data circuit board. This improves the control circuit board, and through the improved control circuit board, the suspension sensor has a fault diagnosis function, thereby improving the reliability of the suspension sensor.
[0090] In some embodiments, the control circuit board 3 is provided with a control circuit, see [reference]. Figure 2 The diagram shows a first structural schematic of a control circuit, which consists of a first connector 1, a second connector 2, a third connector 3, a gap detection circuit 4, an acceleration circuit 5, a control chip circuit 6, a power supply circuit 7, a data storage module 8, and a communication module 9.
[0091] The first input terminal of the second connector 2 is connected to the gap measuring probe 7, and the output terminal of the second connector 2 is connected to the input terminal of the gap detection circuit 4.
[0092] Specifically, the second connector 2 receives the gap signal sent by the gap measuring probe 7 and sends the gap signal to the gap detection circuit 4. The second connector 2 can provide an excitation signal to the gap measuring probe 7. The excitation signal is a key factor in the normal operation of the gap measuring probe 7 and ensuring the accuracy of the measurement. By providing an appropriate excitation signal, the performance of the gap measuring probe 7 can be improved and the reliability of the measurement results can be guaranteed.
[0093] The first output terminal of the gap detection circuit 4 is connected to the first input terminal of the acceleration circuit 5, and the second output terminal of the gap detection circuit 4 is connected to the second input terminal of the second connector 2.
[0094] Understandably, the gap detection circuit 4 receives the gap signal sent by the second connector 2, preprocesses it, and then sends the preprocessed gap signal to the acceleration circuit 5 and the second connector 2. When the second connector 2 receives the preprocessed gap signal, it sends it to the gap measurement probe 7 to ensure that the gap measurement probe 7 can accurately and stably acquire and process gap data.
[0095] The second input terminal of the acceleration circuit 5 is connected to the accelerometer 4 in the suspension sensor, and the output terminal of the acceleration is connected to the first input terminal of the control chip.
[0096] Specifically, the acceleration circuit 5 receives the acceleration value from the suspension sensor detected by the accelerometer 4, and converts the pre-processed gap signal, sending it to the control chip for processing.
[0097] The second input terminal of the control chip circuit 6 is connected to the output terminal of the data storage module 8, the first output terminal of the control chip circuit 6 is connected to the first input terminal of the communication module 9, the second output terminal of the control chip circuit 6 is connected to the input terminal of the data storage module 8, and the third output terminal of the control chip circuit 6 is connected to the first input terminal of the third connector 3.
[0098] It should be noted that the control chip circuit 6 diagnoses whether the acceleration value and the converted gap signal are both greater than the preset threshold. If both the acceleration value and the processed gap signal are greater than the preset threshold, it is determined that the suspension sensor is faulty, the diagnostic result is obtained, and the diagnostic result is sent to the data storage module 8 for storage through the third connector 3.
[0099] In addition, the control chip circuit 6 will send the acceleration value and the converted gap signal to the communication module 9.
[0100] The second input terminal of the first connector 1 is connected to the output terminal of the external connector 5 of the suspension sensor, the first output terminal of the first connector 1 is connected to the input terminal of the power supply circuit 7, the second output terminal of the first connector 1 is connected to the second input terminal of the communication module 9, and the third output terminal of the first connector 1 is connected to the input terminal of the external connector 5 of the suspension sensor.
[0101] It should be noted that the first connector 1 receives the acceleration value and the converted gap signal sent by the control chip circuit 6 through the communication module 9, and transmits the acceleration value and the converted gap signal to the suspension controller through the external connector 5 of the suspension sensor, so that the suspension controller can perform diagnosis based on the acceleration value and the converted gap signal. If a fault is diagnosed, the diagnosis result will be transmitted to the control circuit through the external connector 5 of the suspension sensor. If no fault is diagnosed, the suspension controller will perform corresponding processing based on the acceleration value and the converted gap signal.
[0102] In addition, the levitation controller will also send DC24V voltage to the power supply circuit 7 through the external connector 5 of the levitation sensor to power the power supply circuit 7.
[0103] The second input terminal of the third connector 3 is connected to the second output terminal of the wireless transmission circuit in the data circuit board 2, and the output terminal of the third connector 3 is connected to the first input terminal of the data storage circuit in the data circuit board 2.
[0104] It should be noted that, in addition to sending acceleration values and converted gap signals from the acceleration circuit 5 for fault diagnosis, the control chip circuit 6 can also receive acceleration values and gap signals from the suspension sensor sent by the data circuit board 2 via the third connector 3 for fault diagnosis. Optionally, the acceleration values and gap signals from the suspension sensor sent by the data circuit board 2 can be obtained through manual detection.
[0105] It should also be noted that, in addition to sending the diagnostic results to the data storage module 8 for storage, the control chip also sends them to the data storage circuit in the data circuit board 2 via the third connector 3 for storage, so that front-end personnel can also view the diagnostic results of the suspension sensor through mobile devices.
[0106] In addition, the third connector 3 is located above the control chip circuit 6 and is connected to the data circuit board 2, enabling information exchange with the data circuit board 2.
[0107] In the suspension sensor disclosed in this utility model, the problem that the suspension sensor cannot diagnose its own faults can be solved by the control circuit, and the fault can be quickly located.
[0108] In some embodiments, combined with Figure 2 See Figure 3 The diagram shows a second structural schematic of a control circuit, wherein the gap detection circuit 4 includes a gap signal excitation circuit 41 and a gap signal conditioning circuit 42.
[0109] The input terminal of the gap signal excitation circuit 41 is connected to the output terminal of the second connector 2, and the output terminal of the gap signal excitation circuit 41 is connected to the input terminal of the gap signal conditioning circuit 42.
[0110] Understandably, the gap signal excitation circuit 41 is used to receive the gap signal sent by the second connector 2 and send the gap signal to the gap signal conditioning circuit 42 for processing. The gap signal excitation circuit 41 is also used to generate an excitation signal and transmit the excitation signal to the gap measurement probe 7 through the second connector 2.
[0111] The output of the gap signal conditioning circuit 42 is connected to the input of the acceleration circuit 5.
[0112] Specifically, the gap signal conditioning circuit 42 demodulates the gap signal received from the gap signal excitation circuit 41 and sends it to the acceleration circuit 5.
[0113] It should be noted that the gap signal excitation circuit 41 is located below the second connector 2, and the gap signal conditioning circuit 42 is located below the gap signal excitation circuit 41. It should also be noted that the suspension sensor of this invention has four gap measurement probes 7, designated as gap 1 to gap 4, and each gap measurement probe 7 has a different position and detection location. The suspension controller analyzes the four gap signals and calculates the parameters of two to three of them. Therefore, the suspension sensor has a total of four gap detection circuits 4: gap 1, gap 2, gap 3, and gap 4. The gap signal excitation circuit 41 is for gap 1, and the gap signal conditioning circuit 42 is for gap 4.
[0114] In the suspension sensor disclosed in this utility model, the gap signal is demodulated by the gap detection circuit, which can detect potential problems or faults in the suspension sensor, such as signal strength decrease or interference increase. This helps the subsequent control chip diagnosis. Furthermore, the demodulation processing of the gap detection circuit can extract accurate and clear gap information from the complex gap signal, ensuring that the suspension sensor can accurately measure and analyze the gap.
[0115] In some embodiments, combined with Figure 2 and Figure 3 See Figure 4 The diagram shows a third structural schematic of a control circuit. The acceleration circuit 5 includes: a first acceleration connector 51, a first acceleration conditioning circuit 511, a first AD module 5111, a second acceleration connector 52, a second acceleration conditioning circuit 522, and a second AD module 5222.
[0116] The input terminal of the first acceleration connector 51 is connected to the first output terminal of the accelerometer 4 in the suspension sensor, and the output terminal of the first acceleration connector 51 is connected to the input terminal of the first acceleration conditioning circuit 511.
[0117] Understandably, the first acceleration connector 51 is used to power the accelerometer 4, receive the acceleration value detected by the accelerometer 4 from the suspension sensor, and then send the acceleration value to the first acceleration conditioning circuit 511 for processing.
[0118] The output of the first acceleration conditioning circuit 511 is connected to the first input of the first AD module 5111.
[0119] Specifically, the first acceleration conditioning circuit 511 conditions the received acceleration value, thereby processing the acceleration value into a precise, stable and easy-to-analyze form to ensure the accuracy and reliability of the acceleration value measurement.
[0120] The second input terminal of the first AD module 5111 is connected to the first output terminal of the gap detection circuit 4, and the output terminal of the first AD module 5111 is connected to the first input terminal of the control chip circuit 6.
[0121] Specifically, the first AD module 5111 converts the received gap signal into a binary digital signal and the received conditioned acceleration value into a binary digital signal, and sends the two converted binary digital signals to the control chip circuit 6.
[0122] The input terminal of the second acceleration connector 52 is connected to the second output terminal of the accelerometer 4 in the suspension sensor, and the output terminal of the second acceleration connector 52 is connected to the input terminal of the second acceleration conditioning circuit 522.
[0123] It should be noted that the specific implementation of the second acceleration connector 52 is consistent with the specific implementation of the first acceleration connector 51. Therefore, the explanation of the second acceleration connector 52 can refer to the explanation of the first acceleration connector 51 above, and will not be repeated here.
[0124] The output of the second acceleration conditioning circuit 522 is connected to the first input of the second AD module 5222.
[0125] It should be noted that the specific implementation of the second acceleration conditioning circuit 522 is consistent with the specific implementation of the first acceleration conditioning circuit 511. Therefore, the explanation of the second acceleration conditioning circuit 522 can refer to the explanation of the first acceleration conditioning circuit 511 above, and will not be repeated here.
[0126] The second input terminal of the second AD module 5222 is connected to the second output terminal of the gap detection circuit 4, and the output terminal of the second AD module 5222 is connected to the second input terminal of the control chip circuit 6.
[0127] It should be noted that the specific implementation of the second AD module 5222 is consistent with the specific implementation of the first AD module 5111. Therefore, the explanation of the second AD module 5222 can refer to the explanation of the first AD module 5111 above, and will not be repeated here.
[0128] It should also be noted that both the first accelerometer connector 51 and the second accelerometer connector 52 use SIP5 single-row pins, which are symmetrically distributed on the left and right sides. The accelerometer 4 communicates with the control circuit board 3 through the SIP5 single-row pins.
[0129] In addition, the second input terminal of the first AD module 5111 and the second input terminal of the second AD module 5222 are both connected to the gap signal conditioning circuit 42 in the gap detection circuit 4.
[0130] In the suspension sensor disclosed in this utility model, the acceleration circuit can acquire the acceleration value of the suspension sensor and convert the received gap signal and the acquired acceleration value, thereby making the subsequent signal processing, transmission, storage and analysis more efficient, reliable and flexible. This, in turn, improves diagnostic accuracy.
[0131] In some embodiments, combined with Figure 2 , Figure 3 and Figure 4 See Figure 5 The diagram shows a fourth structure of a control circuit, wherein the control chip circuit 6 includes: a first control chip 61 and a second control chip 62.

The second output terminal of the first control chip 61 is connected to the first input terminal of the data storage module 8. The third output terminal of the first control chip 61 is connected to the first input terminal of the second control chip 62. The fourth output terminal of the first control chip 61 is connected to the first input terminal of the communication module 9.
[0133] Understandably, the first input terminal of the first control chip 61 is connected to the first AD module 5111 in the acceleration circuit 5, and is used to receive two converted binary digital signals, namely the acceleration value and the gap signal, and to perform fault diagnosis based on the two converted binary digital signals. The first control chip 61 is also used to directly transmit the two converted binary digital signals to the communication module 9, thereby playing a communication transmission role.
[0134] It should be noted that there is information interaction between the first control chip 61 and the second control chip 62, thereby achieving data sharing: transmitting levitation sensor data or processing results so that the second control chip 62 can perform further processing or decision-making. Cooperative control: enabling task allocation and coordination among different control chips, optimizing overall system performance. Error detection and fault tolerance: the first control chip 61 can transmit its status information to the second control chip 62 so that the latter can monitor and handle potential errors or faults. System expansion: increasing system flexibility, handling more complex application requirements through the cooperation of multiple control chips.
[0135] The second input terminal of the second control chip 62 is connected to the second output terminal of the acceleration circuit 5.

[0136] Understandably, the second input terminal of the second control chip 62 is connected to the second AD module 5222 in the acceleration circuit 5, and is used to receive two converted binary digital signals, namely the acceleration value and the gap signal, and to perform fault diagnosis based on the two converted binary digital signals. This allows the determination of whether the diagnostic results of the first control chip 61 and the second control chip 62 are consistent, thereby ensuring the accuracy of the diagnosis.
[0137] In some embodiments, the first control chip 61 and the second control chip 62 are both FPGA chips, thereby realizing the calibration, processing, and transmission of gap signals and acceleration values according to protocol requirements.
[0138] In the suspension sensor disclosed in this utility model, the suspension sensor has a fault diagnosis function through the control chip circuit, and the layout of the control circuit board is also improved to a certain extent, thereby reducing the failure rate and improving the reliability of the suspension sensor.
[0139] In some embodiments, combined with Figure 2 , Figure 3 Figure 4 ,as well as Figure 5 See Figure 6 The diagram shows a fifth structural schematic of a control circuit, wherein the data storage module 8 includes a first memory and a second memory.
[0140] The input terminal of the first memory is connected to the first output terminal of the first control chip 61, and the output terminal of the first memory is connected to the second input terminal of the first control chip 61.
[0141] The input terminal of the second memory is connected to the second output terminal of the second control chip 62, and the output terminal of the first memory is connected to the third input terminal of the second control chip 62.
[0142] In one embodiment, both the first memory and the second memory are Flash memory, used to store data and diagnostic results sent by the control chip, thereby adding data storage function to the control circuit board 3 and realizing the storage function of gap signal and acceleration value of the suspension sensor.
[0143] In addition, the first memory and the second memory are used to store calibration data of the gap signal and acceleration value. The first memory and the second memory look up the table according to the two refined numbers converted by the first AD module 5111 and the second AD module 5222, and retrieve the corresponding calibration data from the first memory and the second memory and send it to the corresponding control chip, so that the control chip can perform fault diagnosis on the converted gap signal and acceleration value based on the calibration data.
[0144] In some embodiments, combined with Figure 2 , Figure 3 Figure 4 , Figure 5 ,as well as Figure 6 See Figure 7 The diagram shows a sixth structural schematic of a control circuit, where the communication module 9 includes an RS485 transmitting circuit and an RS485 receiving circuit.

[0147] It should be noted that the RS485 transmitting circuit and RS485 receiving circuit contain a total of 10 RS485 communication modules, located above connector 1. The RS485 transmitting circuit consists of 1 to 5 RS485 communication modules, used to transmit and calibrate the acceleration values received by gap 1, gap 2 and the first acceleration connector 51. The RS485 receiving circuit consists of 6 to 10 RS485 communication modules, used to transmit and calibrate the acceleration values received by gap 3, gap 4 and the first acceleration connector 51.
[0148] It should also be noted that among the 10 RS485 communication modules included in the RS485 transmitting and receiving circuits, 6 RS485 transmitting circuits and 4 RS485 receiving circuits are located above connector 1. The first memory FPGA connects to 3 RS485 transmitting circuits and 2 RS485 receiving circuits, and the second memory FPGA connects to 3 RS485 transmitting circuits and 2 RS485 receiving circuits. The 10 RS485 communication modules are arranged from left to right.
[0149] It should also be noted that the RS485 transmitting circuit converts the four binary digital signals transmitted by the first control chip 61 and the second control chip 62 into differential signals in the RS485 standard format, and drives the transmission line for long-distance transmission to the first connector 1. The RS485 receiving circuit receives the differential signals from the first connector 1, converts them back into digital data, and provides them for processing by the first control chip 61 and the second control chip 62. Therefore, based on the coordinated operation of the RS485 transmitting and receiving circuits, stable remote data transmission and reception can be achieved.
[0150] In some embodiments, combined with Figure 2 , Figure 3 Figure 4 , Figure 5 , Figure 6 ,as well as Figure 7 See Figure 8 The diagram shows a seventh structural schematic of a control circuit. The power supply circuit 7 includes: a first EMC module, a first power supply module, a second power supply module, a third power supply module, a second EMC module, a fourth power supply module, a fifth power supply module, and a sixth power supply module.

[0152] The output terminal of the second power module is connected to the input terminal of the third power module.
[0153] It should be noted that, based on the connection relationship of the first control chip 61, the first AD module 5111, and the first memory, they are located above the third power supply module and arranged in an "L" shape. The input terminal of the second EMC module is connected to the fourth output terminal of the first connector 1, the first output terminal of the second EMC module is connected to the input terminal of the fourth power supply module, and the second output terminal of the second EMC module is connected to the input terminal of the fifth power supply module.
[0154] The output terminal of the fifth power module is connected to the input terminal of the sixth power module.
[0155] It should be noted that, based on the connection relationship between the second control chip 62, the second AD module 5222, and the second memory, the second control chip, the second AD module, and the second memory are located above the sixth power supply module and are arranged symmetrically with the first control chip 61, the first AD module 5111, and the first memory in an inverted "L" shape.
[0156] It should also be noted that the first EMC module, the first power module, the second power module, and the third power module are located to the left of the first connector 1, arranged sequentially from bottom to top. The second EMC module, the fourth power module, the fifth power module, and the sixth power module are located to the right of the first connector 1, arranged sequentially from bottom to top.
[0157] It should also be noted that the first and fourth power supply modules are DC24V / ±15V power supply modules, used to provide power to the operational amplifier and accelerometer 4. The operational amplifier is included in the gap signal excitation circuit 41 and the acceleration conditioning circuit. The third and sixth power supply modules are the chip power supplies for the control chip circuit 6, the data storage module 8, and the communication module 9.
[0158] In addition, the first EMC module and the second EMC module are used to filter and process the data sent by the first connector 1 before sending it to the corresponding power module, thereby protecting the circuit.
[0159] It should be emphasized that, as can be seen from the above description, apart from the first connector 1, the second connector 2, and the third connector 3, the components and modules contained in the gap detection circuit 4, the communication module 9, the acceleration circuit 5, the control chip circuit 6, the power supply circuit 7, and the data storage module 8 are all duplicated. Therefore, the control circuit board 3 can be divided into two groups of processing circuits. When any one group of processing circuits fails, it will not affect the other group of processing circuits, and the other group of processing circuits will take on the diagnostic function of the suspension sensor.
[0160] Therefore, the first set of processing circuits consists of gaps 1 and 2 in the gap detection circuit 4, the first acceleration connector 51, the first acceleration conditioning circuit 511, the first EMC module, the first power module, the second power module, the third power module, the first control chip 61, the first memory, the first AD module 5111, and one set of RS485 transmitting and receiving circuits in the communication circuit.

Moreover, the power and ground of the first and second sets of processing circuits are completely isolated during PCB layout, and they do not affect each other.

[0164] The input terminal of the wireless transmission circuit is connected to the second output terminal of the third connector 3, and the second output terminal of the wireless transmission circuit is connected to the second input terminal of the third connector 3.
[0165] It should be noted that the data storage circuit uses a high-speed microSD card as the storage medium. The use of a microSD card facilitates easy removal and replacement; therefore, when large amounts of data need to be read, a card reader can be used to connect to a computer to view the stored data. The wireless transmission circuit uses a dedicated flat wireless communication antenna to enhance the wireless communication signal.
[0166] It should also be noted that the wireless transmission circuit also transmits data to the receiving end, providing data for the receiving end's detection. The receiving end refers to the levitation controller or other host computer software.
[0167] In the suspension sensor disclosed in this utility model, card reading or wireless transmission is realized through a data circuit board, which can quickly read the gap signal and acceleration value of the suspension sensor, providing data support for the suspension controller and track status detection.
