[0002] The ZPW-2000A type non-insulated track circuit is currently the mainstream circuit for automatic block signaling systems in China. Each track circuit includes a main track circuit and a tuning zone circuit. By performing electrical disconnection checks on the track circuits, if the track circuit exhibits electrical characteristics indicating a potential rail breakage, the train control system determines that there is a risk of rail breakage, issues an alarm, and prevents the train from entering the track with the risk of a rail breakage.

[0003] However, in practical applications, due to factors such as varying cable lengths in different track sections and variable operating environments, the voltage of the signal in the tuning zone track may exceed the preset threshold, causing the train control system to issue incorrect alarm messages. Therefore, the detection accuracy of the tuning zone track circuit in the existing ZPW-2000A type uninsulated track circuit is relatively low. Summary of the Invention

[0023] By connecting the adjacent terminals and the terminals of the attenuation disk, a fourth voltage value of the output signal of the attenuator is obtained;

[0024] When the fourth voltage value is within the preset standard voltage range, the fourth voltage is used as the output signal voltage value of the attenuator.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0052] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0053] In one exemplary embodiment, such as Figure 1 As shown, a method for adjusting the small track of a ZPW-2000 track circuit is provided. This method is applied to electronic devices and includes steps S101 to S103. The method includes:

[0054] S101. For each tuning zone in the railway track, obtain the first voltage value of the small track input signal of the tuning zone.

[0055] The track circuit covers the entire railway track and includes multiple track sections, each consisting of a main track and a tuning section track. The tuning section track, acting as an electrical insulation joint, is 29 meters long.

[0056] Each track section includes transmitting and receiving equipment. The transmitting equipment sends the main track input signal, which is transmitted via the main track rail in the opposite direction of train travel to the receiving equipment of this track section. The transmitting equipment also sends the sub-track input signal, which is transmitted via the tuning zone rail in the direction of train travel to the receiving equipment of the next track section.

[0057] Specifically, such as Figure 2 As shown, Figure 2 The illustration shows two smaller tracks and one main track, with the smaller tracks representing the tuning zone tracks in this embodiment. The transmitting device for this track section sends a main track input signal, which is transmitted via the main track rail in the opposite direction of train travel to the receiving device for this track section. The transmitting device for the subsequent track section sends smaller track input signals, which are transmitted via the smaller track rail in the same direction of train travel to the receiving device for this track section.

[0058] Furthermore, the transmission process of downlink segment signals is illustrated using three adjacent track sections as an example. For instance... Figure 3 As shown:

[0059] Figure 3 Three track segments are illustrated: a 1-track segment, a 2-track segment, and a 3-track segment. The 1-track segment consists of segments ab and bc, and the tuning zone track status of the 1-track segment is checked by the receiving device 2JS of the 2-track segment.

[0060] Similarly, the 2-track section consists of the cd and de segments, and the track status of the tuning zone of the 2-track section is checked by the 3JS receiving equipment of the 3-track section. The 3-track section consists of the ef and fg segments, and the track status of the tuning zone of the 3-track section is checked by the 4JS receiving equipment of the 4-track section.

[0061] S102. Locate the first terminal corresponding to the first voltage value in the preset receive level adjustment table.

[0062] The preset receiving level adjustment table includes a mapping relationship between voltage values ​​and terminals. Each terminal is used to connect a resistor. The preset receiving level adjustment table is obtained by using a fuzzy control model to perform fuzzy reasoning on different voltage values ​​and different cable lengths.

[0063] Specifically, the electronic device inputs the fiber optic cable length and voltage value into the fuzzy control model. The fuzzy control model maps these values ​​to fuzzy linguistic quantities using a membership function, and calculates the membership degree of the input parameters and each preset fuzzy subset. After calculating the membership degree of the input parameters and each preset fuzzy subset, the membership degrees of each preset fuzzy subset are superimposed to obtain the fuzzy inference of the input parameters. The fuzzy inference is then defuzzified to obtain the terminal corresponding to the input parameters.

[0064] S103. Connect the first terminal and the terminal of the attenuation disk, adjust the first voltage value, and obtain the second voltage value of the output signal of the attenuator corresponding to the attenuation disk.

[0065] Understandably, each terminal is connected to a resistor, and the resistors are connected in series. By connecting the terminals of the attenuation disk to different terminals, different resistors can be connected in series to achieve voltage division processing of the small track input signal, thereby reducing the voltage value of the small track input signal.

[0066] Using the method provided in this application, for each tuning zone in the railway track, the first voltage value of the small track input signal in the tuning zone is obtained. Then, the first terminal corresponding to the first voltage value is found in a preset receive level adjustment table. By connecting the first terminal and the terminal of the attenuation disk, the voltage value of the attenuator's output signal is obtained. The preset receive level adjustment table is obtained through fuzzy reasoning for different voltages and different cable lengths. The preset receive level adjustment table can accurately find the wiring method of the resistors corresponding to different combinations of optical cable lengths and voltages. By connecting the found first terminal to the terminal of the attenuation disk and connecting different resistors in series, the voltage of the small track input signal can be adjusted to the voltage range allowed by the receiving device, avoiding false alarm messages caused by the small track input signal voltage value exceeding the voltage range allowed by the receiving device, thus improving detection accuracy.

[0067] Regarding S103 mentioned above, the attenuator is located between the receiving equipment and the optical cable. The small track input signal is transmitted to the attenuator via the optical cable, and the attenuator reduces the voltage of the small track input signal through a series resistor. Specifically... Figure 4 As shown, Figure 4 An exemplary schematic diagram of an attenuator is shown. A11-A19 are the terminals corresponding to the train traveling in the positive direction, each terminal is connected to a resistor, i.e., resistors RF11-RF19 are connected in series. C11-C19 are the terminals corresponding to the train traveling in the opposite direction, each terminal is connected to a resistor, i.e., resistors RZ11-RZ19.

[0068] The following combination Figure 5 This section introduces the method for constructing a preset receive level adjustment table, such as... Figure 5 As shown, the method includes:

[0069] S501. For each tuning zone, obtain the actual cable length from the signal transmitting device to the tuning zone and the third voltage value of the tuning zone.

[0070] The third voltage value can be the input signal voltage value of the small track under different transmission signals.

[0071] S502. Input the actual cable length and the third voltage value into the fuzzy control model so that the fuzzy control model can perform fuzzy reasoning on the actual cable length and the third voltage value to obtain the terminal corresponding to the third voltage value.

[0072] In one example, such as Figure 6 As shown, Figure 6An exemplary fuzzy control model is shown, which includes a signal builder, a fuzzy logic controller, a gain module, a constant module, an adder module, and an oscilloscope module.

[0073] The Signal Builder is used to generate custom input signals. The Fuzzy Logic Controller performs fuzzy processing on the received input signal to obtain a fuzzy control output, and then defuzzifies the fuzzy control output to obtain the output signal. Gain is used to scale the output signal. Constant is used to generate a constant. Sum is used to superimpose the scaled output signal and the generated constant. Scope is used to display the signal waveform.

[0074] S503. Construct a preset receiving level adjustment table according to the terminal corresponding to the third voltage value and the third voltage value.

[0075] Using the method provided in this application, for each tuning zone, the actual cable length and third voltage value corresponding to that tuning zone are obtained. The actual cable length and each third voltage value are input into a fuzzy control model, allowing the fuzzy control model to perform fuzzy inference based on different combinations of cable length and third voltage value, obtaining the terminals corresponding to different third voltage values ​​under that actual cable length. Repeating the above steps yields the terminals corresponding to different combinations of cable length and voltage value. A preset receiving level adjustment table is constructed using the output results of the fuzzy control model, improving the accuracy of the preset receiving level adjustment table. Subsequently, the voltage value of the small track input signal is adjusted using the preset receiving level adjustment table, improving the detection accuracy of the track circuit in the tuning zone.

[0076] In some embodiments of this application, before step S502 above, where the actual cable length and the third voltage value are input into the fuzzy control model for fuzzy inference based on the actual cable length and the third voltage value to obtain the terminal corresponding to the third voltage value, the method further includes:

[0077] The actual cable length is compensated to the maximum value of the target length range based on the actual cable length. This yields the simulated cable length.

[0078] The length range is preset according to current specifications.

[0079] In one example, the length intervals are divided into (0, 7.5], (7.5, 10], (10, 12.5], and (12.5, 15], in kilometers. If the actual cable length is less than 7.5 km, the cable length is compensated to 7.5 km; if the actual cable length is greater than 7.5 km but less than 10 km, the cable length is compensated to 10 km; if the actual cable length is greater than 10 km but less than 12.5 km, the cable length is compensated to 12.5 km; and if the actual cable length is greater than 12.5 km but less than 15 km, the cable length is compensated to 15 km.

[0080] Furthermore, with the lightning protection simulation network disk disconnected, the actual cable length is compensated to the maximum value of the target length range according to the target length range in which the actual cable length is located, thus obtaining the simulated cable length.

[0081] Understandably, the surge protection simulation network board contains electronic components such as resistors and capacitors. By disconnecting the surge protection simulation network board, the influence of the electronic components in the surge protection simulation network board on the voltage value of the small track input signal can be reduced.

[0082] Accordingly, in S502 above, the actual cable length and the third voltage value are input into the fuzzy control model for fuzzy inference based on the actual cable length and the third voltage value to obtain the terminal corresponding to the third voltage value. Specifically, this can be implemented as follows:

[0083] The simulated cable length and the third voltage value are input into the fuzzy control model to perform fuzzy inference on the simulated cable length and the third voltage, so as to obtain the terminal corresponding to the third voltage value.

[0084] The method provided in this application compensates the actual cable length to the maximum value of the target length range, thereby aligning all cables within that range to the maximum value and ensuring consistency in cable length. Since different cable lengths result in different inherent inductance and resistance, compensating for the actual cable length avoids the influence of inductance and resistance outside the cable itself on detection accuracy, thus improving the accuracy of subsequent detection.

[0085] In some embodiments of this application, after adjusting the first voltage value in S103 above, at the terminal connecting the first terminal and the attenuation disk, to obtain the second voltage value of the output signal of the attenuator corresponding to the attenuation disk, the method further includes:

[0086] Step 1: If the second voltage value exceeds the preset standard voltage range, obtain the adjacent terminal of the first terminal in the preset receive level adjustment table.

[0087] The preset standard voltage range is determined based on the voltage range allowed by the receiving device. In one example, the preset standard voltage range is 155±10mV.

[0088] Step 2: Connect the adjacent terminals and the terminals of the attenuation disk to obtain the fourth voltage value of the attenuator's output signal.

[0089] It should be noted that when measuring the voltage value of the output signal at the attenuation disc rail outlet, a frequency selection test is performed using the same carrier frequency as the small track input signal. Specifically, the signal transmitting device uses a high-frequency signal to transmit low-frequency information. The center frequencies of the high-frequency signal mainly include four types: 1700Hz, 2000Hz, 2300Hz, and 2600Hz. The frequency carrying the small track input signal is determined through the frequency selection test, thereby accurately measuring the voltage value of the small track input signal.

[0090] Step 3: When the fourth voltage value is within the preset standard voltage range, use the fourth voltage value as the output signal voltage value of the attenuator.

[0091] Using the method provided in this application embodiment, after connecting the first terminal and the terminals of the attenuation disk, the second voltage value of the attenuator output signal is detected. If the second voltage value exceeds a preset standard voltage range, it indicates that the second voltage value still exceeds the voltage measurement range allowed by the receiving device. Therefore, the adjacent terminal of the first terminal is searched in a preset receive level adjustment table, and the adjacent terminal and the terminals of the attenuation disk are reconnected. It is then determined whether the fourth voltage value of the output signal is within the preset standard voltage range. If it is within the preset standard voltage range, the fourth voltage value is used as the output signal voltage value. If it still exceeds the preset standard voltage range, the search continues, starting from the adjacent terminal, for the adjacent terminal until the voltage value of the output signal is within the element and standard voltage range. In this way, the voltage value of the attenuator output signal can be guaranteed to be within the voltage measurement range allowed by the receiving device, thereby avoiding false alarms caused by the voltage value exceeding the preset standard voltage range and improving detection accuracy.

[0092] In some embodiments of this application, the received voltage of the receiving device is obtained after processing the voltage value of the small track input signal. The electronic device can also adjust the voltage of the small track input signal transmitted by the transmitting device next time according to the received voltage.

[0093] The following combination Figure 4 This application introduces a small track adjustment circuit and a small track adjustment method according to embodiments of the present application, focusing on the small track adjustment circuit and... Figure 4The track adjustment circuits in the illustrated embodiments have the same structure, including a forward track adjustment branch and a reverse track adjustment branch. Depending on the train's direction of travel, the receiving device will be connected to different end track circuits. Therefore, the track circuits are adjusted in both forward and reverse directions.

[0094] The small track adjustment circuit is a variable series voltage divider attenuator. By shorting the cross-line to any intermediate tap terminal and selecting the total series resistance, it divides and attenuates the small track voltage input to the tuning zone, matching the small track input voltage to the receiver's rated operating level.

[0095] The small track adjustment circuit includes a positive direction small track adjustment branch and a negative direction small track adjustment branch.

[0096] Taking the input terminal of the positive direction small rail adjustment branch as A11 and the output terminal as A19 as an example:

[0097] The internal series resistors are RF11-RF19, and the intermediate tap terminals of each resistor are A12~A19. The resistance values ​​of RF11-RF29 are 8Ω, 12Ω, 20Ω, 39Ω, 57Ω, 75Ω, 100Ω, 220Ω and 330Ω respectively.

[0098] Taking the input terminal of the reverse-direction rail adjustment branch as C11 and the output terminal as C30 as an example:

[0099] The internal series resistors are RZ11-RZ19, and the intermediate tap terminals of each resistor are C12~C19. The resistance values ​​of RZ11-RZ19 are 8Ω, 12Ω, 20Ω, 39Ω, 57Ω, 75Ω, 100Ω, 220Ω and 330Ω.

[0100] Combination Figure 4 The illustrated embodiment describes the complete steps of the small track adjustment method:

[0101] Step A: Acquire the original input voltage of the small rail.

[0102] The original rail input voltage is the signal picked up by the tuning zone transmitting equipment of the adjacent section through the electrical insulation joint. .

[0103] Step B: Calculate the total attenuation required.

[0104] The electronic equipment calculates the voltage attenuation ratio based on the on-site cable length, rail surface level, and rated input requirements of the receiving equipment. The total series resistance of the small track adjustment circuit is then determined based on this voltage attenuation ratio. .

[0105] Specifically, total series resistance Determined by the tapped terminals used for bridging. For example, bridging A11 and A15, the total series resistance... = 8+12+20+39+57 = 136Ω.

[0106] It should be noted that, in Figure 4 In the illustrated embodiment, the larger the tap number of the bridging connection, the larger the total series resistance, the stronger the attenuation, and the smaller the output voltage.

[0107] Step C: Distinguish the wiring according to the driving direction.

[0108] Different circuit branches are selected to achieve voltage division depending on the direction of train travel.

[0109] Specifically, when the train is running in the forward direction, the small track input signal is connected to the forward small track adjustment branch A11~A19, and A11 is shorted with a jumper wire. When the train is running in the reverse direction, the small track input signal is connected to the reverse branch C11~C19, and C11 is shorted with a jumper wire.

[0110] Step D: Obtain the receiving voltage of the small rail.

[0111] The receiving voltage of the track is the second voltage value of the output signal in the above embodiment, which is calculated according to the following formula:

[0112]

[0113] in, The total series resistance selected for the jumper. Input the equivalent internal resistance to the receiving device.

[0114] Step E: Closed-loop adjustment.

[0115] Specifically, the receiving device collects the received voltage in real time. Compare with the preset voltage upper limit and preset voltage lower limit The output amplitude of the adjacent section's transmitting equipment is adjusted in the reverse direction, thereby changing the small track input voltage of the output signal of the next adjacent transmitting equipment. This achieves level closed-loop stability.

[0116] Small track input voltage closed-loop regulation formula .

[0117] in, The small track input signal voltage, which is output by the transmitting device in the next cycle and sent to the tuning area, After passing through the small track adjustment circuit, the receiving device actually collects the voltage. : Preset maximum voltage limit for the small rail to receive. : Preset minimum voltage limit for small rail receiving.

[0118] like This indicates that the receiving voltage of the small rail is too high, so the transmitting equipment should be controlled to reduce its output. ;

[0119] like This indicates that the receiving voltage of the small rail is too low; therefore, the transmitting equipment should be controlled to increase its output. ;

[0120] like The transmission voltage remains unchanged.

[0121] In summary, the formula for calculating the matching resistance of the small rail is as follows: .

[0122] Where k: the parameter for selecting the tap position on the secondary winding of the small-rail regulating transformer, which is obtained by looking up a table. : The total series resistance of the positive direction small rail adjustment branch or the positive direction small rail adjustment branch.

[0123] Based on the above formula, the parameter k can be determined according to the required attenuation voltage, and the total series resistance of the matching circuit can be calculated. ,according to Identify the corresponding tap, complete the jumper settings, and achieve static level setting for the small track.

[0124] In one example, the calculated total series resistance The resistance is 334Ω. In the positive direction small rail adjustment branch, the resistance is accumulated step by step: 8+12+20+39+57+75+100=311Ω (A17), 311+220=531Ω (A18). Therefore, the total series resistance is... 334Ω is between A17 and A18, so you can choose the A18 setting for higher attenuation.
