[0061] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0062] Figure 1 It is a flow chart of the track circuit information collection method provided by the present invention, such as Figure 1 As shown, the method includes:

[0063] S1. Based on the phase-modulation lightning arrester, the power signal at the receiving end of the track circuit is converted into a multi-channel output signal, and the multi-channel output signals are collected respectively according to the collection units deployed in the track boards of each system;

[0064] S2. Determine the target output signal collected by the main system track board according to the computing units deployed in each system track board;

[0065] S3. Determine the information collection result of the track circuit receiving end according to the target output signal;

[0066] Among them, each track board is connected to the phase-adjusting lightning arrester.

[0067] It should be noted that the execution subject of the above method may be a computer device.

[0068] Optionally, a track section with a power transmission end and a power receiving end is used as an example for explanation: Figure 2 The power receiving end of the track circuit forms two power signals through the power line (Q) and return line (H), and is wired to the distribution cabinet through the trackside terminal box (XB-1). Then, it is processed by the phase-modulating lightning arrester (TFQ) of the distribution cabinet and converted into multiple output signals (for example, 4 output signals) to each track board (GDB) in the object controller cabinet.

[0069] The following is an explanation using the A series track board and the B series track board. Two output signals GS1-Q and GS1-H are sent to the A series track board, and the other two output signals GS2-Q and GS2-H are output to the B series track board.

[0070] The acquisition unit deployed on the A series track board collects the output signals GS1-Q and GS1-H, and the acquisition unit deployed on the B series track board collects the output signals GS2-Q and GS2-H.

[0071] After the acquisition units of the A series track board and the B series track board respectively collect GS1-Q, GS1-H, GS2-Q and GS2-H, the computing units deployed inside the A series track board and the B series track board are used to determine which one of the A series track board and the B series track board belongs to the main system track board.

[0072] If it is determined that the A series track board belongs to the main system track board, the target output signal is obtained based on the output signal (GS1-Q and GS1-H) collected by the A series track board; similarly, if the B series track board belongs to the main system track board, the target output signal is obtained based on the output signal (GS2-Q and GS2-H) collected by the B series track board.

[0073] Finally, the collected target output signal is used as the information collection result of the power receiving end of the track circuit.

[0074] It should be noted that each track board can transmit the information collection results of the track circuit power receiving end to the computer interlocking (CI) through the standard CAN communication protocol, and the computer interlocking maintenance workstation processes the information collection results. At the same time, the computer interlocking maintenance workstation sends the processed information collection results to the maintenance support system (MSS) through the wireless network to realize the full sharing of relevant information.

[0075] The track circuit information collection method provided by the present invention adopts a track circuit board to collect the information of the track circuit, which is completely isolated from the track circuit receiving end and does not affect the operation of the track circuit, meets the requirements of circuit failure and safety, and realizes the self-collection of the track circuit information.

[0076] Further, in one embodiment, the step S1 of collecting multiple output signals respectively according to the collection units deployed in the track boards of each system may specifically include:

[0077] S11, collecting a first output signal according to a first acquisition unit deployed in a first series track board and a first output terminal of a phase-modulating lightning arrester;

[0078] S12. Collect the second output signal according to the second acquisition unit deployed in the second track board and the second output terminal of the phase-modulating lightning arrester.

[0079] Alternatively, see Figure 3 According to the working principle of the track circuit, such as the 50HZ track circuit, the terminals 62, 52, 83, and 73 of the phase-modulating lightning arrester are output terminals. The first output terminals 62 and 52 of the phase-modulating lightning arrester are used as sampling points of the first series track board, such as the A series track board, and the second output terminals 83 and 73 of the phase-modulating lightning arrester are used as sampling points of the second series track board, such as the B series track board.

[0080] According to the sampling points of the A series track board and the acquisition unit deployed in the A series track board (i.e., the first acquisition unit), the first output signal (GS1-Q and GS1-H) is collected; and according to the sampling points of the B series track board and the acquisition unit deployed in the B series track board (i.e., the second acquisition unit), the second output signal (GS2-Q and GS2-H) is collected.

[0081] It should be noted that the object controller is a security system, such as Figure 4 As shown, the object controller adopts a two-by-two-out-of-two architecture. The A-series track board and the B-series track board deployed in it both have the function of collecting information on the power receiving end of the track circuit. In order to ensure the uniqueness of the information, the main system track board and the spare system track board are switched using the reversing unit, so that only the information collected by the main system (Pr) track board is output, and the information collected by the spare system (St) track board is not output.

[0082] The track circuit information collection method provided by the present invention solves the problems of redundant equipment, large workload of collection and wiring, and poor collection accuracy in the prior art of using track circuit receivers, track test disks, and microcomputer monitoring track circuit collection equipment to collect track circuit information, and realizes automatic collection of track circuit information through various track boards.

[0083] Furthermore, in one embodiment, step S11 may specifically include:

[0084] S111, isolating an output signal of a first output terminal according to a first group of isolation units deployed in a first acquisition unit;

[0085] S112. Collecting the isolated first output signal and the frequency of the first output signal according to the first acquisition module deployed in the first acquisition unit;

[0086] S113, collecting the isolated second output signal and the frequency of the second output signal according to the second acquisition module deployed in the first acquisition unit;

[0087] S114, isolating the subordinate local power supply signal of the first power supply panel connected to the first system track board according to the second group of isolation units deployed in the first acquisition unit;

[0088] S115, collecting the isolated first slave local power signal and the second slave local power signal respectively according to the first collection module and the second collection module;

[0089] S116, determining a first phase angle collected by the first collection module according to the first output signal and the first subordinate local power supply signal;

[0090] S117, determining a second phase angle collected by a second collection module according to the second output signal and the second subordinate local power supply signal;

[0091] S118, determining a first output signal according to the acquisition results of the first acquisition module and the second acquisition module;

[0092] The first acquisition module and the second acquisition module are connected to the first group of isolation units and the second group of isolation units respectively.

[0093] Optionally, the information collection of the power receiving end of the track circuit is realized by the collection unit inside each track board. In actual scenarios, the collection principle of the collection unit deployed inside each track board is the same. The collection unit mainly includes an isolation unit, a collection module, a computing CPU and a communication output port. Specifically:

[0094] like Figure 5 As shown, the first acquisition unit includes two groups of isolation units (the first group of isolation units: GL1, GL2 and the second group of isolation units: GL3, GL4), wherein the isolation units use high-resistance isolation and are integrated into the A-series track board. Among them, GL1 and GL2 isolate the output signals (GS1-Q and GS1-H) of the first output terminal of the phase-modulating lightning arrester; GL3 and GL4 isolate the subordinate local power supply signals (JJZ110 and JJF110) of the first power supply panel connected to the A-series track board.

[0095] Among them, the sampling points of the subordinate local power supply signals of the first power supply panel connected to the A series track board are the track power subordinate local power supply signals JJZ110 and JJF110 output by the first power supply panel.

[0096] The acquisition unit (first acquisition unit) in the A series track board includes two acquisition modules, namely the first acquisition module and the second acquisition module;

[0097] The first acquisition module is used to acquire the isolated output signals GS1-Q and GS1-H (first output signals: GS1-1Q and GS1-1H), the frequency of the first output signal, and the first phase angle.

[0098] Specifically, by collecting the line voltages of the first output signals GS1-1Q and GS1-1H output by the isolation unit GL1, the first output signal, namely the first voltage value U1, and the frequency of the first output signal are calculated.

[0099] The first phase angle is obtained by collecting the slave local power supply signal (JJZ110 and JJF110) output by the isolation unit GL3 and then calculating the phase difference between the slave local power supply signal (JJZ110 and JJF110) and the first output signal output by GL1.

[0100] Since the collected first voltage value, the frequency of the first output signal, and the first phase angle are all analog quantities, they need to be quantized and then sent to the analog-to-digital conversion module ADC for processing.

[0101] The second acquisition module collects the line voltage of the second output signal GS1-2Q, GS1-2H output by the isolation unit GL2, and measures the second output signal, ie, the second voltage value U1, and the frequency of the second output signal.

[0102] The second phase angle is obtained by collecting the slave local power supply signal (JJZ-110 and JJF-110) output by the isolation unit GL4 and then calculating the phase difference between the slave local power supply signal and the second output signal.

[0103] Since the collected first voltage value, second voltage value, frequency of the first output signal and the second output signal, the first phase angle and the second phase angle are all analog quantities, they need to be quantized and sent to the analog-to-digital conversion module ADC for processing.

[0104] Analog-to-digital converter (ADC): performs A / D conversion, converts the voltage values ​​output by the first acquisition module and the second acquisition module into digital information, and sends it to the operation unit CPU after processing.

[0105] Operation unit CPU: The CPU is the core of the track board. It manages the first acquisition unit according to the pre-set program, temporarily stores the converted data, and communicates with the CI maintenance workstation through the CAN bus via the communication output port.

[0106] Operation unit CPU: It can realize the operation and processing of track circuit voltage, frequency and phase angle acquisition data, determine the adjustment / branching status of the track circuit, and at the same time determine whether the acquisition results of each track board should be output externally based on the main / standby information of each board.

[0107] At the same time, the CPU of the operation unit adopts a 2-out-of-2 structure, including CPU1 and CPU2. CPU1 is connected to the first acquisition module, and CPU2 is connected to the second acquisition module. The two CPUs compare the acquisition results of the first acquisition module (first voltage value, frequency of the first output signal, first phase angle) and the acquisition results of the second acquisition module (second voltage value, frequency of the second output signal, second phase angle), respectively, and obtain the first output signal after the safety and gate, and output it to the communication output port. The output information includes: the voltage value, frequency value and phase angle of the power receiving end of the track circuit.

[0108] The calculation method of the first voltage value and the second voltage value is as follows:

[0109] CPU1 and CPU2 use the SPI bus to read the ADC respectively, and can read the instantaneous voltage value sent to the ADC entrance by the operational amplifier circuit at the receiving end of the track circuit. According to the circuit principle and amplification factor, the instantaneous voltage is converted into instantaneous current. The voltage data is collected every 1ms, and it is stored in a memory that can store 60 data in a loop, so that the memory segment always stores the instantaneous current data within the last 60ms (3 power frequency cycles). Finally, the root mean square value of the 60 instantaneous currents is calculated (first calculate the sum of squares, then calculate the mean, and finally take the square root) to obtain the effective value of the last 60ms. Through the above algorithm, the effective value of the voltage at the receiving end of the track (i.e., the first voltage value and the second voltage value) can be obtained.

[0110] Communication output port: It has the function of converting the data output by the computing CPU into data applied by standard communication protocol and outputting it to the outside through the CAN bus.

[0111] The track circuit information collection method provided by the present invention can automatically monitor the working parameters (voltage, frequency and phase angle) of the track circuit to determine whether the track circuit is working normally, thereby providing data support for maintenance personnel.

[0112] Furthermore, in one embodiment, step S12 may specifically include:

[0113] S121, isolating an output signal of the second output terminal according to a third group of isolation units deployed in the second acquisition unit;

[0114] S122. Collecting the isolated third output signal and the frequency of the third output signal according to the third acquisition module deployed in the second acquisition unit;

[0115] S123. Collect the isolated fourth output signal and the frequency of the fourth output signal according to the fourth acquisition module deployed in the second acquisition unit;

[0116] S124, isolating the subordinate local power supply signal of the second power supply panel connected to the second system track board according to the fourth isolation unit deployed in the second acquisition unit;

[0117] S125, collecting the isolated third slave local power signal and the fourth slave local power signal respectively according to the third collection module and the fourth collection module;

[0118] S126, determining a third phase angle collected by a third collection module according to the third output signal and the third subordinate local power supply signal;

[0119] S127, determining a fourth phase angle collected by the second collection module according to the fourth output signal and the fourth subordinate local power supply signal;

[0120] S128, determining a second output signal according to the acquisition results of the third acquisition module and the fourth acquisition module;

[0121] The third acquisition module and the fourth acquisition module are connected to the third group of isolation units and the fourth group of isolation units respectively.

[0122] Alternatively, if Figure 6 As shown, the second acquisition unit includes two groups of isolation units (the third group of isolation units: GL5, GL6 and the fourth group of isolation units: GL7, GL8), wherein the isolation units use high-resistance isolation and are integrated into the B-series track board. Among them, GL5 and GL6 isolate the output signals (GS2-Q and GS2-H) of the second output terminal of the phase-modulating lightning arrester; GL7 and GL8 isolate the subordinate local power supply signals (JJZ110 and JJF110) of the second power supply panel connected to the B-series track board.

[0123] Among them, the sampling points of the subordinate local power supply signals of the second power supply panel connected to the B series track board are the track power subordinate local power supply signals JJZ110 and JJF110 output by the second power supply panel.

[0124] The acquisition unit (second acquisition unit) in the B series track board includes two acquisition modules, namely the third acquisition module and the fourth acquisition module;

[0125] The third acquisition module is used to realize the acquisition of the isolated output signals GS2-Q and GS2-H (the third output signals: GS2-1Q and GS2-1H), the frequency acquisition of the third output signal and the acquisition of the third phase angle.

[0126] Specifically: by collecting the line voltage of the third output signal GS2-1Q, GS2-1H output by the isolation unit GL5, the third output signal, that is, the third voltage value U3 and the frequency of the second output signal are calculated.

[0127] The third phase angle is obtained by collecting the slave local power supply signal (JJZ110 and JJF110) output by the isolation unit GL7 and then calculating the phase difference between the slave local power supply signal (JJZ110 and JJF110) and the third output signal output by GL5.

[0128] Since the collected third voltage value, the frequency of the third output signal, and the third phase angle are all analog quantities, they need to be quantized and then sent to the analog-to-digital conversion module ADC for processing.

[0129] The fourth acquisition module: collects the line voltage of the fourth output signal GS2-2Q, GS2-2H output by the isolation unit GL6, and measures the fourth output signal, that is, the fourth voltage value U4, and the frequency of the fourth output signal.

[0130] The fourth phase angle is obtained by collecting the slave local power supply signal (JJZ-110 and JJF-110) output by the isolation unit GL8 and then calculating the phase difference between the slave local power supply signal and the fourth output signal.

[0131] Since the collected third voltage value, fourth voltage value, frequency of the third output signal and fourth output signal, third phase angle and fourth phase angle are all analog quantities, they need to be quantized and sent to the analog-to-digital conversion module ADC for processing.

[0132] Analog-to-digital converter (ADC): performs A / D conversion, converts the voltage values ​​output by the third acquisition module and the fourth acquisition module into digital information, and sends it to the operation unit CPU after processing.

[0133] The CPU of the operation unit also adopts a 2-out-of-2 structure, including CPU3 and CPU4. CPU3 is connected to the third acquisition module, and CPU4 is connected to the fourth acquisition module. The two CPUs compare the acquisition results of the third acquisition module (third voltage value, frequency of the third output signal, third phase angle) and the acquisition results of the fourth acquisition module (fourth voltage value, frequency of the fourth output signal, fourth phase angle), respectively, and obtain the second output signal after the safety and gate, and output it to the communication output port. The output information includes: the voltage value, frequency value and phase angle of the power receiving end of the track circuit.

[0134] The calculation method of the third voltage value and the fourth voltage value is the same as the calculation method of the first voltage value and the second voltage value.

[0135] The track circuit information collection method provided by the present invention can determine whether the track circuit is working normally by automatically monitoring the working parameters (voltage, frequency and phase angle) of the track circuit, thereby providing data support for maintenance personnel. At the same time, since each system track board adopts a 2-out-of-2 architecture, each system track board can synchronously collect the working parameters of the track circuit. Even if the main system track board fails, real-time monitoring of the working parameters of the track circuit can still be achieved.

[0136] Furthermore, in one embodiment, step S2 may specifically include:

[0137] S21, determining the main track board according to the judgment result of the computing unit on the main and standby information of each track board;

[0138] S22, determining the target output signal according to the acquisition result of the main system track board;

[0139] Among them, each series of track plates includes a first series of track plates and a second series of track plates.

[0140] Optionally, the primary and backup information of each series track board is judged according to the computing unit deployed inside each series track board, for example, the primary and backup information of the first series track board (A series track board) and the second series track board (B series track board) is judged, and according to the judgment result, the one of the A series track board and the B series track board that belongs to the primary system track board is determined.

[0141] Assuming that, after judgment, the A series track board is the main track board and the B series track board is the backup track board, the target output signal is determined according to the acquisition result of the A series track board.

[0142] The track circuit information collection method provided by the present invention realizes information collection on the power receiving end of the track circuit by adopting various track boards (such as dual-series track boards). Subsequently, the collected information can be sent to a computer for interlocking to realize docking and communication with various maintenance systems. The method has strong compatibility and is convenient for operation and maintenance management.

[0143] Furthermore, in one embodiment, step S3 may further specifically include:

[0144] S4, sending the information collection results to the computer interlocking maintenance workstation, so that the computer interlocking maintenance workstation can determine the voltage value, frequency and phase angle of the target output signal according to the information collection results;

[0145] S5. When the track is in an occupied state, if the voltage value is higher than a first preset voltage threshold, it is determined that the track circuit is abnormal, and an alarm is issued;

[0146] S6. When the track is in an occupied state, if the voltage value is lower than the second preset voltage threshold, it is determined that the track circuit is abnormal, and an alarm is issued;

[0147] S7. If the frequency is outside the preset frequency threshold range, it is determined that the track circuit is abnormal and an alarm is issued;

[0148] S8. If the phase angle is outside the preset phase angle threshold range, it is determined that the track circuit is abnormal and an alarm is issued.

[0149] Optionally, the information collection results are sent to the computer interlocking maintenance workstation, so that the computer interlocking maintenance workstation can determine the voltage value, frequency and phase angle of the target output signal based on the information collection results. The computer interlocking maintenance workstation can determine the track occupation (branching) or idle (adjustment) status by itself, and based on the voltage value, frequency and phase angle of the target output signal collected, combined with the working status of the track circuit, it can determine whether to alarm, which is specifically implemented as follows:

[0150] The computer interlocking maintenance workstation processes the voltage value, frequency and phase angle of the target output signal to form voltage, phase angle and frequency curves.

[0151] Compare the voltage value, frequency and phase angle of the collected target output signal with the 50HZ track circuit characteristics (normal working value) to make an alarm judgment:

[0152] When the track is in the occupied state (shunt state), the signal voltage of the track circuit (i.e., the voltage value of the target output signal) should be lower than the first preset voltage threshold, such as 7.4 V. If the collected voltage value is higher than 7.4 V, the voltage of the track circuit is considered abnormal, and the system alarm prompts.

[0153] When the track is in an idle state (adjustment state), the signal voltage of the track circuit should be higher than a second preset voltage threshold, such as 15 V. If the collected voltage value is lower than 15 V, the voltage of the track circuit is considered abnormal, and a system alarm is issued.

[0154] The frequency of the target output signal of the track circuit should be within the preset frequency threshold range, for example, 50Hz±0.3Hz. If the collected frequency is lower than 49.7Hz or higher than 50.3Hz, the power supply frequency of the track circuit is considered abnormal and a system alarm is issued.

[0155] The phase angle value of the target output signal of the track circuit should be within the preset phase angle threshold, for example, -30° to +30°. If the collected phase angle is lower than -30° or exceeds +30°, the phase angle of the track circuit is considered abnormal and a system alarm is issued.

[0156] During the use of the track circuit, the collected working parameters (voltage value, frequency and phase angle of the target output signal) may change. Different alarm thresholds (such as preset voltage threshold, preset frequency threshold and preset phase angle threshold) are set in the computer interlocking maintenance workstation to achieve accurate alarm. At the same time, the threshold value can be adjusted in time according to the use of the track circuit.

[0157] The track circuit information collection method provided by the present invention can collect the track circuit information by the fully electronic computer interlocking maintenance workstation, thereby realizing real-time monitoring of the working parameters of the track circuit and accurate alarm.
