Description

Technical Field

[0001] The present invention relates to the technical field of railway equipment monitoring, and particularly to a transponder monitoring method, system, device, storage medium and program product. Background Art

[0002] A transponder is a point device used to transmit information from the ground to a train at a specific location. It is usually installed on the sleeper in the middle of the track and is in a dormant state. When a train passes by, the transponder is activated by the electromagnetic energy emitted by the on-vehicle antenna (BTM) to work, so that the transponder sends the stored data message to the train, providing fixed and real-time variable information such as basic line parameters and train operation target data for the train. It is a key device to ensure train operation safety and improve transportation efficiency. Therefore, it is very necessary to regularly monitor the performance and faults of the transponder.

[0003] Currently, there are mainly two ways to monitor transponders. One is to monitor the transponder by maintenance personnel through periodic inspections, which is time-consuming, laborious and inefficient; the other is to use a transponder monitoring device to perform regular inspections on the transponder (that is, regularly emit electromagnetic energy to the transponder to obtain the data message stored in the transponder), and send the inspection information back to the control room to determine whether the transponder is working properly. However, when the antenna of the on-vehicle device and the transponder monitoring device emit electromagnetic energy to the transponder at the same time, this method will cause mutual interference, thus affecting the on-vehicle device's normal reception of the data message sent by the transponder.

[0032] In order to enable those skilled in the art of the present technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0034] It should be noted that by the maintenance personnel monitoring the transponder in the way of periodic inspection, this way is time-consuming, laborious and inefficient. And when using a transponder monitoring device to conduct regular inspections on the transponder, when the antenna of the on-vehicle device and the transponder monitoring device simultaneously transmit electromagnetic energy to the transponder, it will cause mutual interference and thus affect the on-vehicle device's normal reception of the data message sent by the transponder.

[0035] Based on this, the embodiments of the present invention provide a transponder monitoring method, Figure 1The flowchart of a transponder monitoring method provided by an embodiment of the present invention is applicable to scenarios such as monitoring the working status and fault conditions of transponders. This method can be executed by a response monitoring device in a transponder monitoring system, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, preferably a mobile terminal, a desktop computer, a laptop computer, a server, etc.

[0036] As Figure 1 shown, the transponder monitoring method provided by an embodiment of the present invention is applied to a transponder monitoring system, which includes a response monitoring device and a monitoring and operation and maintenance device. The response monitoring device is arranged below the transponder.

[0037] Among them, the response monitoring device can be understood as a device for monitoring the working status of the transponder and the transmitted message information. It can judge whether the transponder is working properly and whether the transmitted data is correct by receiving the signal sent by the transponder. The monitoring and operation and maintenance device can be understood as a device deployed indoors for monitoring the transponder status and alarming for abnormalities. Specifically, it can be used to send monitoring instructions to the response monitoring device, receive the transponder-related data sent back by the response monitoring device, and can display, store, and alarm for faults the real-time or historical relevant data reflecting the transponder status after judgment and processing. Optionally, the monitoring and operation and maintenance device can be an indoor industrial computer, a server, etc. When the monitoring and operation and maintenance device is a server, it can run an analysis software system to automatically and efficiently analyze a large number of transponder signals, and store the analysis results and monitoring status, etc. The analysis results and monitoring status can be accessed by a remote browser, thereby improving the monitoring efficiency and accuracy.

[0038] Optionally, communication transmission between the response monitoring device and the monitoring and operation and maintenance device is carried out through a power line carrier mode.

[0039] Specifically, power line carrier modems are respectively deployed in the response monitoring device and around the monitoring and operation and maintenance device to extract and modulate communication data from the power line. Through the power line carrier mode, communication data transmission is directly carried out using the power line, realizing the integration of equipment power supply and communication on existing railway lines, reducing additional communication equipment and wiring costs, improving the overall work efficiency, and having the advantages of strong anti-interference ability, high security, fast transmission rate, and wide coverage. Communication transmission between the response monitoring device and the monitoring and operation and maintenance device can also be carried out through wireless communication and other methods, which are not limited in this embodiment.

[0040] The method is executed by the response monitoring device and specifically may include:

[0041] S101. When it is detected that a train enters and exits, generate passing train information and transmit the passing train information to the monitoring and operation and maintenance device.

[0042] Among them, the passing train information can be understood as information that can accurately reflect the passing situation of a train at a specific transponder position. The passing train information may include the code reflecting the passing of the train, the entry and exit times of the train, the position information of the transponder, etc.

[0043] In this embodiment, the manner in which the response monitoring device detects that a train has entered and exited can be to collect signals, images, etc. of the train entering and exiting by setting vibration sensors, infrared sensors, cameras and other collection devices around the response monitoring device, and send them to the response monitoring device to detect whether a train has entered and exited. When it is detected that a train has entered and exited, passing train information is generated, and the passing train information is transmitted to the monitoring and operation and maintenance device to inform the monitoring and operation and maintenance device of the information that a train has just passed.

[0044] S102. Receive a first transponder activation monitoring instruction sent by the monitoring and operation and maintenance device, where the first transponder activation monitoring instruction is generated by the monitoring and operation and maintenance device based on the passing train information.

[0045] Among them, the first transponder activation monitoring instruction can be understood as an automatic instruction for ensuring that the transponder is activated and monitored at least once during the gap between two train passes.

[0046] In this embodiment, when the monitoring and operation and maintenance device receives the passing train information, the monitoring and operation and maintenance device immediately generates at least one first transponder activation monitoring instruction and sends it to the response monitoring device.

[0047] S103. Send a first activation energy to the transponder according to the first transponder activation monitoring instruction.

[0048] Among them, the first activation energy can be understood as the activation energy generated according to the first transponder activation monitoring instruction, which can be an energy signal of 27 MHz and is used to activate the transponder to enter the working state.

[0049] In this embodiment, the response monitoring device actively sends the first activation energy to the transponder according to the received first transponder activation monitoring instruction to activate the transponder.

[0050] S104. Receive a first energy response signal sent by the transponder after obtaining the first activation energy, and monitor the transponder through the first energy response signal.

[0051] Among them, the first energy response signal can be understood as the signal sent by the transponder using the first activation energy. The first energy response signal may include the information stored in the transponder or the real-time information received from the line-side electronic unit (LEU), such as the basic line parameters (such as line gradient, track section), line speed information (such as the maximum allowable line speed, the maximum allowable train speed), temporary speed limit information (such as when the train operation speed is restricted due to construction, etc., providing temporary speed limit information to the train), whistle information, and train positioning information, etc.

[0052] In this embodiment, the receiving transponder receives the first energy response signal sent by using the first activation energy after obtaining the first activation energy, and extracts and analyzes the information in the first energy response signal that can reflect the working state of the transponder, such as extracting and analyzing the state parameter information such as the amplitude and frequency of the first energy response signal, and verifying the transponder message data contained in the first energy response signal to determine whether the transponder fails or the working state is normal.

[0053] According to the above description, the judgment result can also be sent to the monitoring and operation and maintenance equipment for display, storage, and / or alarm. The extracted state parameter information and transponder message data can also be sent to the monitoring and operation and maintenance equipment for further analysis and judgment, such as comparing with the received historical state parameter information and transponder message data, and judging whether the performance of the transponder has decreased through the change of the state parameter information and the accuracy of the message data. If the decrease is relatively serious, a warning signal can be sent to inform the maintenance personnel to check and replace it; it can also be compared with the historical state parameter information of other similar transponders received to judge whether the transponder is interfered, etc.

[0054] It can be understood that when it is determined that the transponder has a fault or the working state is abnormal, a fault alarm is carried out. The fault alarm method can be to display the faulty transponder in red in the node topology diagram, or to broadcast the faulty transponder in the form of voice alarm; it can also be to alarm in the form of high-brightness red flashing in the event status bar; it can also be to push the fault information to the maintenance personnel by means of text message, email, etc. At the same time, data such as state parameter information, transponder message data, operation records, and historical fault events can be stored for subsequent management and viewing.

[0055] It should be noted that the transponder monitoring device is always in the on state, that is, it can normally receive the signals sent by the transponder, receive the signals and images of the train entering and leaving sent by the acquisition device, and complete data processing and other tasks, but does not send activation energy to the transponder in real time to monitor the transponder.

[0056] A transponder monitoring method provided in this embodiment generates passing train information when it detects that a train enters and exits, and transmits the passing train information to the monitoring and operation and maintenance device; receives a first transponder activation monitoring instruction sent by the monitoring and operation and maintenance device, where the first transponder activation monitoring instruction is generated by the monitoring and operation and maintenance device based on the passing train information; sends a first activation energy to the transponder according to the first transponder activation monitoring instruction; receives a first energy response signal sent by the transponder after obtaining the first activation energy, and monitors the transponder through the first energy response signal. By sending the first activation energy to the transponder after detecting that a train enters and exits and receiving the first energy response signal sent by the transponder, this method realizes at least one activation monitoring of the transponder adaptively during the interval between two passing trains, ensures the timeliness of transponder monitoring, improves the monitoring efficiency, and avoids affecting the normal working function of the transponder when the train passes. At the same time, the adaptive start mechanism reduces the start times of the transponder, thereby reducing the failure rate of the transponder, and further reducing the frequency and cost of maintenance and replacement; monitoring the transponder through the first energy response signal can early warn the transponder with potential faults or fault conditions, effectively ensuring the safe operation of the train.

[0057] As a first alternative embodiment of this embodiment, the transponder monitoring system further includes at least one vibration sensor, the vibration sensor surrounds the response monitoring device and is arranged on the steel rail around the response monitoring device, and the power required by the vibration sensor is provided by the response monitoring device.

[0058] Among them, the output signal of the vibration sensor is a waveform voltage signal from -5V to 5V, and the amplitude and frequency of the waveform are linearly related to the vibration characteristics.

[0059] Exemplarily, two vibration sensors can be respectively deployed on both sides of the steel rail 1 meter away from the vibration sensor, and the positions of the two vibration sensors on each side are spaced 1 meter apart.

[0060] Correspondingly, generating passing train information when it detects that a train enters and exits can be specifically implemented as the following steps:

[0061] a1) Convert the signals output by each vibration sensor received into frequency domain signals respectively, and determine whether the signals output by the vibration sensor have passing train characteristics according to the amplitude values of the frequency domain signals within a specific frequency range.

[0062] Among them, the passing train characteristics can be understood as the characteristics reflected by the vibration signals generated by the vibration of the track caused by the passing of the train.

[0063] In this embodiment, after receiving the signals output by each vibration sensor, the signals are converted to the frequency domain by means such as fast Fourier transform. According to the operating characteristics of the high-speed train, the frequency domain signals between 120 Hz and 6 kHz are intercepted and the amplitude values of the frequency domain signals are calculated. If the amplitude value is greater than the set threshold, it is determined that the signal output by the vibration sensor has the characteristic of a passing train, that is, it is considered that a train has passed through the position where the vibration sensor is located.

[0064] b1) If it has the characteristic of a passing train, determine whether the duration of the passing train characteristic is greater than the set time threshold. If so, determine the signal with the passing train characteristic as a complete passing train signal.

[0065] In this embodiment, if it has the characteristic of a passing train, determine whether the duration of the passing train characteristic is greater than the set time threshold. It can be understood that the time threshold can be set according to the time when a general high-speed train passes through the transponder. If the duration of the passing train characteristic is greater than the set time threshold, then the segment of the signal with the passing train characteristic and the signals without the passing train characteristic within a certain period of time adjacent to the front and back of this segment of the signal can be jointly determined as a complete passing train signal.

[0066] c1) In the same time period, if the vibration sensors with a complete passing train signal account for more than half of all the vibration sensors deployed around the same transponder detection device, and the difference between the maximum amplitude values of the passing train signals in the frequency domain is less than the preset first amplitude threshold, generate passing train information.

[0067] Among them, the first amplitude threshold can be understood as the threshold for judging whether the maximum amplitude values of each frequency domain signal are similar, that is, if it is less than the first amplitude threshold, it is considered that the maximum amplitude values of each frequency domain signal are close.

[0068] In this embodiment, if it is judged that among all the vibration sensors deployed around the same transponder within the same time period, more than half of the vibration sensors output signals with complete passing train signals, and the difference between the maximum amplitude values of the frequency domain signals of each passing train signal is less than the preset first amplitude threshold, then generate passing train information.

[0069] Exemplarily, following the above example description, 4 vibration sensors can be set. When the response monitoring device determines that 3 out of the 4 vibration sensors output signals with complete passing train signals, determine the maximum amplitude values of the passing train signals of the above 3 vibration sensors in the frequency domain, and judge whether the difference between the 3 maximum amplitude values is less than the preset first amplitude threshold. The first amplitude threshold can be set to 5% of the maximum value among the maximum amplitude values to flexibly adapt to various situations. If it is less than the preset first amplitude threshold, generate passing train information that can reflect the passing of a train.

[0070] In the above technical solution of this embodiment, by analyzing whether the signal output by the vibration sensor has a train-passing feature, whether the train-passing feature is greater than the set time threshold, and whether the sensors with the train-passing feature are in the majority, it is accurately determined whether a train has passed, so as to ensure that the corresponding transponder can be started for timely and effective monitoring during each interval between two train passages, improving the train operation safety.

[0071] As the second alternative embodiment of this embodiment, on the basis of the above embodiment, it further includes:

[0072] a2) Receiving a second transponder activation monitoring instruction sent by the monitoring and operation and maintenance device, and sending second activation energy to the transponder according to the second transponder activation monitoring instruction, where the second transponder activation monitoring instruction is generated by the monitoring and operation and maintenance device based on the trigger signal received for the monitoring start control.

[0073] Among them, the second transponder activation monitoring instruction can be understood as an instruction sent by the monitoring and operation and maintenance device to the response monitoring device after receiving the trigger signal for the monitoring start control when the service object (such as maintenance personnel) has the need to monitor the transponder, so as to activate and monitor the transponder in a timely manner. The monitoring start control can be understood as a user interface element or function for starting the response monitoring system for monitoring, and can be in the form of a button, shortcut, slider, drop-down box, etc. The monitoring start control allows selecting to start monitoring all transponders so as to obtain the status and data of all transponders at the same time. It also allows starting the monitoring of these specific transponders by inputting or selecting the line address information of specific transponders, which is applicable to monitoring transponders deployed on new lines, after modifying stored information (such as setting or canceling temporary speed limit commands), and those that have not been monitored for a long time. The line address information can be composed of the section number, station number, group number, and the device serial number within the group. The second activation energy can be understood as the energy for activating the transponder generated according to the second transponder activation monitoring instruction.

[0074] In this embodiment, after the monitoring and operation and maintenance device receives the trigger signal generated by operating (such as clicking, dragging, etc.) the monitoring start control, it generates a second transponder activation monitoring instruction and sends the instruction to the corresponding response monitoring device. When the response monitoring device receives the second response activation monitoring instruction, it sends a second activation instruction to the transponder according to the second response activation monitoring instruction.

[0075] b2) Receiving a second energy response signal sent by the transponder after obtaining the second activation energy, and monitoring the transponder through the second energy response signal.

[0076] Among them, the second energy response signal can be understood as the signal sent by the transponder using the second activation energy, and may include the information stored in the transponder or the real-time information received from the line side electronic unit (LEU).

[0077] In this embodiment, the receiving transponder acquires the second energy response signal sent after obtaining the second activation energy, and monitors the working state of the transponder by analyzing the message data in the second energy response signal and the status parameter information such as the amplitude and frequency of the second energy response signal, and transmits the message data and status parameter information to the monitoring and operation and maintenance equipment for further analysis, monitoring, result display, etc. Exemplarily, the integrity of the transponder message transmission channel, the working state of the transponder, and whether the temporary speed limit command is executed can be monitored.

[0078] The above technical solution of this embodiment, after receiving the second transponder activation monitoring instruction generated and sent by the monitoring and operation and maintenance equipment based on the monitoring start control trigger signal, sends the second activation energy to the transponder, so as to monitor the transponder through the second energy response signal sent by the transponder, realizing active, timely and efficient monitoring of one or more transponders deployed on new lines, after modifying the stored information, and not monitored for a long time, so as to discover transponders with potential faults in advance, reduce the emergency braking situation of trains caused by transponder failures, and thus improve the train operation safety and transportation efficiency.

[0079] As the third optional embodiment of this embodiment, it further includes:

[0080] a3) When the train passes by the transponder, automatically receive the third energy response signal sent by the transponder, and the third energy response signal is generated after the transponder obtains the third activation energy sent by the on-vehicle antenna.

[0081] Among them, the third activation energy can be understood as the energy used to activate the transponder sent by the on-vehicle antenna when the train passes by the transponder. The third energy response signal can be understood as the signal sent by the transponder using the third activation energy, and may include the information stored in the transponder or the real-time information received from the line side electronic unit (LEU), so that the train control system can read and process this information to realize functions such as vehicle-ground communication and train positioning.

[0082] In this embodiment, when the train passes by the transponder, the transponder generates a third energy response signal after receiving the third activation energy sent by the on-vehicle antenna, and sends the third energy response signal to the on-vehicle antenna. During this process, the response monitoring device can automatically receive the third energy response signal sent by the transponder to the on-vehicle antenna, that is, monitor and record the communication situation between the transponder and the train in real time.

[0083] b3) Monitor the transponder based on the third energy response signal.

[0084] In this embodiment, the method of monitoring the transponder based on the third energy response signal may be to verify the message data in the second energy response signal to determine whether the data sent by the transponder is complete and accurate; determine whether the transponder is working properly by checking whether the transponder can normally generate the third energy response signal; and monitor the performance of the transponder, such as the reliability and stability of signal transmission, by analyzing the state parameter information such as the amplitude and frequency of the second energy response signal.

[0085] According to the above technical solution of this embodiment, when the train passes by the transponder, the transponder automatically sends the third energy response signal based on the third activation energy, and the transponder is monitored based on the third energy response signal to monitor the performance and status of the normal operation of the transponder in real time, ensuring the accuracy of train positioning and the reliability of vehicle-ground communication. In particular, it solves the problem that when facing a non-reproducible fault caused by an instantaneous decrease in the performance of the transponder, the train will make an emergency brake, but the cause of the transponder fault cannot be determined.

[0086] As one implementation manner of any of the above embodiments of the present invention, the monitoring of the transponder based on the energy response signal can be further specifically optimized as:

[0087] a4) Convert the received energy response signal into a digital signal and obtain the baseband signal of the digital signal.

[0088] In this embodiment, the method of converting the received energy response signal into a digital signal may be to convert the received energy response signal into a digital signal through an analog-to-digital converter (ADC); the method of obtaining the baseband signal of the digital signal may be to perform digital mixing on the digital signal by using a digital downconverter (DDC), and then filter and sample the mixed signal to extract the I and Q quadrature components, that is, the baseband signal, and store it in the FIFO memory.

[0089] To better understand the above technical solution, a specific example is given here. Figure 2 It is a schematic diagram of the baseband signal extraction principle of a transponder monitoring method provided by an embodiment of the present invention. As Figure 2As shown, a numerically controlled oscillator (NCO) generates 4.23 MHz sine and cosine quadrature signals using a 42.3 MHz clock, reads digital signals collected by an ADC and stored in a double data rate memory (DDR), multiplies them with the generated sine and cosine signals respectively, obtains two orthogonal digital signals DATAI and DATAQ, filters the filtered data through a finite impulse response (FIR) filter, samples the filtered data respectively and stores the sampled data in a FIFO memory.

[0090] b4) Determine the average amplitude of the digital signal. If the average amplitude is greater than a preset second amplitude threshold, execute data analysis logic to determine the amplitude, code rate, and carrier frequency rate of the baseband signal, and record the amplitude, code rate, and carrier frequency rate of the baseband signal as transponder characteristic parameters.

[0091] Among them, the second amplitude threshold can be understood as a threshold for controlling whether to execute data analysis logic, and can be set according to the empirical values of multiple experiments.

[0092] In this embodiment, the average amplitude of the digital signal is determined according to the amplitude values of each sampling point of the digital signal and the number of sampling points. If the average amplitude is greater than the preset second amplitude threshold, the baseband signal is obtained and the data analysis logic is executed on the baseband signal, that is, the amplitude, code rate, and carrier frequency speed of the baseband signal can be determined, and the amplitude, code rate, and carrier frequency rate of the baseband signal are recorded as transponder characteristic parameters.

[0093] To better understand the above technical solution, a specific example is given here. Figure 3 It is a schematic diagram of the data analysis logic of a transponder monitoring method provided by an embodiment of the present invention. As Figure 3As shown, the processing logics such as baseband signal extraction and data analysis can be performed by the FPGA chip inside the response monitoring device. Specifically, the ADC collects two signals, namely the unprocessed energy response signal and the energy response signal processed by the automatic gain control (AGC) circuit. It should be noted that the AGC circuit can process the amplitude of the signal to improve the flatness of the signal amplitude, thereby reducing the zero-crossing drift. The FPGA chip sends the digital signal generated by collecting the unprocessed energy response signal obtained from the ADC to the threshold / amplitude calculation module, calculates the average amplitude of the digital signal, and determines whether the average amplitude is greater than the preset second amplitude threshold; and sends the digital signal generated by collecting the energy response signal processed by the AGC obtained from the AD to the DDR for caching. After the FPGA chip reads the cached data in the DDR, I and Q baseband signals are generated through the DDC and sent to the code rate / carrier frequency calculation module. When the threshold calculation module determines that the average amplitude is greater than the preset second amplitude threshold, it sends a start calculation command to the code rate / carrier frequency calculation module, so that the code rate / carrier frequency calculation module can calculate the code rate and carrier frequency of the baseband signal according to the obtained I and Q baseband signals. At the same time, the calculated average amplitude can be sent to the code rate / carrier frequency calculation module as the amplitude calculation result. It can be understood that the code rate, carrier frequency, and amplitude calculation result of the baseband signal can be read by the CPU inside the response monitoring device through the code rate / carrier frequency calculation module.

[0094] Continuing with the above description, the specific calculation resource configuration can be as follows: ADC sampling is 2 channels, that is, 42.3M * 2CH * 14bit; DDR: write / read; DDC: orthogonal transformation to baseband (4.23MHz carrier frequency); FIR filter; for calculating the amplitude, the real part of amplitude values such as the average amplitude and amplitude median can be taken as the amplitude calculation result; for calculating the carrier frequency, the maximum, minimum, or average value of the carrier frequency over a period of time can be taken, which involves multipliers and adders; the timing control for generating the write DDR pulse and read DDR pulse can be to store in the DDR in real time according to 42.3MHz * 2 * 16bit and read out after a delay τ (τ is written by the CPU and determined by the processing bandwidth); the DDC module uses 1 NCO core and 2 * 2 FIR filters (two signals), that is, a total of 1 NCO and 4 FIR filters (8th order), and the shared logic unit is (2603 * 1 + 686 * 4) * 2-channel signal processing = 5347 * 2 = 10694 ALUT, accounting for 21.8% of the total logic resources of 49000 (LEs). The buffers used in other calculations are not calculated and can be ignored for now.

[0095] Multiplier resources required: A total of 4 * 2 (I, Q) = 8 real - number multiplications (two - time amplitude - square calculations, two channels) are required, approximately 8 multipliers. According to the 5CEFA4F23I7N manual, the contained multiplier resources are 132, so it meets the requirements and approximately occupies 6%. The temporary ones in the frequency - calculation module are not counted for the moment, and the remaining resources in the above discussion far meet the requirements.

[0096] c4) Determine whether the transponder characteristic parameters exceed the limit according to the preset parameter standard range, and generate fault - judgment information regarding the transponder.

[0097] In this embodiment, the parameter standard range can be preset according to the range required by the transponder waveform specification. The parameter standard range can include the ranges set for the amplitude, code rate, and carrier - frequency rate of the base - band signal respectively. By comparing the obtained transponder characteristic parameters with the preset parameter standard, it is determined whether the transponder characteristic parameters are lower or higher than the parameter standard range, and the difference between being lower or higher than the parameter standard range, so as to generate fault - judgment information regarding the transponder. Among them, the fault - judgment information can include a fault - judgment result (such as normal or faulty) and a warning message (such as performance - degradation level information).

[0098] d4) Send the transponder characteristic parameters and the fault - judgment information to the monitoring and operation - maintenance device for further analysis, fault alarm, and / or result display.

[0099] In this embodiment, the transponder characteristic parameters and the fault - judgment information are sent to the monitoring and operation - maintenance device for further analysis, fault alarm, and / or result display. Exemplarily, the monitoring and operation - maintenance device can perform fault alarm and result display on the received fault - judgment information indicating a fault, and can also store the result in the historical events; the monitoring and operation - maintenance device compares the received transponder characteristic parameters with the historical transponder characteristic parameters, or compares them with the transponder characteristic parameters corresponding to other adjacent or transponders on the same line, so as to more accurately determine whether there is a potential fault trend.

[0100] The above - mentioned technical solution of this embodiment increases the accuracy and timeliness of transponder - fault determination by analyzing the amplitude, code rate, and carrier - frequency of the energy - response signal after it is converted into a digital signal, thereby improving the response speed to transponder faults; and sending the transponder characteristic parameters and the fault - judgment information to the monitoring and operation - maintenance device for further analysis, fault alarm, and / or result display can more accurately analyze whether there are potential faults or serious performance degradation in the transponder, and timely prompt the maintenance personnel to check or replace the transponder, improving the train operation safety.

[0101] As the fourth alternative embodiment of this embodiment, it further includes:

[0102] a5) When receiving the status query command sent by the monitoring and operation and maintenance device, perform self-check and generate self-check status information to be sent to the monitoring and operation and maintenance device.

[0103] In this embodiment, when the monitoring and operation and maintenance device generates and sends a status query command to the responding monitoring device at regular intervals or after receiving the trigger signal of the self-check start control, the responding monitoring device performs self-check when receiving the status query command sent by the operation and maintenance monitoring device. The self-check process may include checking each functional module and circuit inside the responding monitoring device to ensure its normal operation. Exemplarily, the self-check content may include checking whether the power supply circuit of the responding monitoring device is normally powered; detecting whether the communication interfaces between the responding monitoring device and the monitoring and operation and maintenance device and the transponder are unobstructed; checking the data integrity of the internal memory of the responding monitoring device to ensure that the stored information is not damaged; testing the signal processing circuit of the responding monitoring device to ensure that it can correctly process the received monitoring instruction for activating the transponder and generate activation energy. When the self-check is completed, the transponder generates self-check status information. These information contain the self-check results, such as whether a fault is detected, the working status of each module, etc. Then, the responding monitoring device sends these self-check status information to the monitoring and operation and maintenance device.

[0104] Correspondingly, after receiving the self-check status information, the monitoring and operation and maintenance device can evaluate the health status of the responding monitoring device. If the self-check result shows that there is a fault or abnormality in the responding monitoring device, the monitoring and operation and maintenance device will trigger the corresponding alarm mechanism and notify the maintenance personnel to conduct inspections and repairs.

[0105] With the above technical solution of this embodiment, by starting the self-check of the responding monitoring device and sending the self-check status information to the monitoring and operation and maintenance device, problems existing in the responding monitoring device can be discovered in time, thereby ensuring the effectiveness and accuracy of transponder monitoring.

[0106] As the fifth alternative embodiment of this embodiment, it further includes:

[0107] a6) Perform configuration address information verification with the monitoring and operation and maintenance device through encrypted communication.

[0108] It is understandable that, according to the actual monitoring requirements and scope of the railway line, the number of response monitoring devices can be flexibly configured, and a unique configuration address information will be written into each response monitoring device during deployment. The configuration address information is preset and used to identify and distinguish different response monitoring devices in the communication network. Exemplarily, the configuration address information of each response monitoring device can be determined according to the preset deployment addresses of each response monitoring device outdoors, and the configuration address information can be written into the deployed response monitoring device through a terminal device (such as a mobile phone, etc.) by means of wired communication (suitable for monitoring scenarios with short distances and fixed positions) or wireless communication (such as 5G communication).

[0109] Continuing with the above description, when it is necessary to expand the monitoring scope, new response monitoring devices can be added at the corresponding positions. After adding, it is necessary to write the configuration address information for them and proofread it with the pre-entered line configuration table in the monitoring and operation and maintenance device. When some response monitoring devices need to be removed due to faults or other reasons, they can be deleted from the system. After deletion, it is also necessary to proofread it with the pre-entered line configuration table in the monitoring and operation and maintenance device to ensure the accurate identification and management of the response monitoring devices by the monitoring and operation and maintenance device, thereby ensuring the correctness and effectiveness of communication.

[0110] In this embodiment, by means of encrypted communication, the method of proofreading the configuration address information with the monitoring and operation and maintenance device can be that the monitoring and operation and maintenance device issues a verification command to the communication interface (slave node) of the response monitoring device through its own communication interface (master node). The verification command contains interface general transfer parameters. The interface general transfer parameters can include the master node call request ID, the format of which is a time string accurate to milliseconds (YYYY_MM_dd_HH_mm_ss_SSS), and its function is to also return this parameter when the interface returns, facilitating the slave node to perform verification. Exemplarily, the master node call request ID (reqId) can be expressed as: "reqId":"2024_03_19_13_23_00_182"; it also includes an access secret key, which is used for the master node to issue a slave node verification notice. Exemplarily, the access secret key (accessKey) can be expressed in the form of accessKey = dev002@ + serial number; it also includes an access encryption string, that is, the master node call request ID (reqId) and the access secret key (secretKey) can be encrypted through an encryption algorithm such as the MD5 algorithm. Exemplarily, the access encryption string can be expressed as secretKey = MD5(reqId + '_BDT_' + accessKey).

[0111] Continuing with the above description, after receiving the verification command sent by the master node, the slave node sends the configuration address information to be verified to the master node so that the master node can perform a correctness verification. The master node can perform the verification according to the pre-input line configuration table of the response detection device. The line configuration table can be composed of the region number, sub-region number, station number, group number, device serial number within the group, and distance information, etc. It should be noted that the slave node needs to send the received interface general transfer parameters and device ID to the master node at the same time. After receiving the configuration address information sent by the slave node and performing a correctness verification, the master node sends the correctness verification result to the slave node. Exemplarily, the correctness verification result may include a verification judgment result (such as a boolean field true or false), a success or failure return code (200 represents success, 500 and others represent failure (only one of the verification judgment result and the code needs to be parsed)), a return description (such as verification success or verification failure), the timestamp of the master node's return result, the reqId passed during the master node's sending, a verification result code (such as 0 = message matching success, 1 = no corresponding configuration file exists, 2 = all numbers are inconsistent, 3 = partial information is inconsistent, 4 = others), a description of the verification result (the Chinese corresponding to the Code), and the correct message (i.e., the correct number information corresponding to the device number (obtained from the configuration file)).

[0112] In the above technical solution of this embodiment, the configuration address information in the response monitoring device is compared with the address information of the response monitoring device pre-entered in the monitoring and operation and maintenance device through encrypted communication to prevent incorrect configurations, thereby ensuring the effectiveness of subsequent monitoring.

[0113] To better understand the transponder monitoring method provided by the embodiments of the present invention, a specific example is given here. Figure 4 It is a schematic diagram of the system architecture of a transponder monitoring method provided by the embodiments of the present invention.

[0114] As Figure 4As shown in the figure, a response monitoring device is installed below the outdoor active balise. The response monitoring device is connected to vibration sensors arranged on the rails on both sides around it through cable lines to provide the required power for each vibration sensor and receive the electrical signals output by the vibration sensors. The response monitoring unit can communicate with the indoor monitoring and operation and maintenance device through 220V power line carrier using the spare line of the ground electronic unit LEU. The LEU spare line is connected to the power line carrier modem deployed indoors through the LEU indoor lightning protection cabinet. The power line carrier modem can extract and modulate communication data from the power line, and modulate the communication data and load it onto the current to be transmitted to the power line. The power line carrier modem can establish connections with multiple devices. It should be noted that the response monitoring device is also configured with a power line carrier modem to achieve the same function, and the active balise can also be connected and communicate with the LEU through cable lines. In addition, the LEU indoor wiring cabinet is connected to the monitoring and operation and maintenance device through reserved cables to also send the message data sent to the LEU through the LEU indoor wiring cabinet and lightning protection cabinet to the monitoring and operation and maintenance device, so that the monitoring and operation and maintenance device can judge whether the balise has executed the commands contained in the message data transmitted by the LEU by comparing the received message data sent by the balise.

[0115] Figure 5 It is a schematic structural diagram of a balise monitoring system provided by an embodiment of the present invention. As Figure 5 shown, the system includes: a response monitoring device 51, a monitoring and operation and maintenance device 52, and vibration sensors 53. The response monitoring device is arranged below the balise, the vibration sensors surround the response monitoring device and are arranged on the rails around the response monitoring device. The power required by the vibration sensors is provided by the response monitoring device, and communication transmission is carried out between the response monitoring device and the monitoring and operation and maintenance device by means of power line carrier.

This method sends first activation energy to the transponder after detecting that a train enters and exits, and receives the first energy response signal sent by the transponder, thereby realizing at least one activation monitoring of the transponder adaptively during the interval between two passing trains, ensuring the timeliness of the transponder monitoring, improving the monitoring efficiency, and avoiding affecting the normal working function of the transponder when the train passes. At the same time, the adaptive start mechanism reduces the start times of the transponder, thereby reducing the failure rate of the transponder, and further reducing the frequency and cost of maintenance and replacement; monitors the transponder through the first energy response signal, and can early warn the transponder with potential faults or fault conditions, effectively ensuring the safe operation of the train.

[0124] If it has passing train characteristics, determine whether the duration of the passing train characteristics is greater than a set time threshold. If so, determine the signal with the passing train characteristics as a complete passing train signal;

[0125] Within the same time period, if the vibration sensors with a complete passing train signal account for more than half of all the vibration sensors arranged around the same transponder detection device, and the difference between the maximum amplitude values of each passing train signal in the frequency domain is less than a preset first amplitude threshold, generate passing train information.
