[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The embodiment of the present application provides a method for automatically configuring a simulated network disk, which is applied to an adjustment implementation system. The adjustment implementation system may include an operation unit, a storage unit, an execution unit, and a terminal. The operation unit, the storage unit, and the execution unit may be connected to a track circuit system through the terminal, such as Figure 1As shown, the method may include:

[0047] S10, the operating unit obtains the total cable length and the actual cable length;

[0048] S11, the operating unit obtains the simulated cable length according to the total cable length and the real cable length;

[0049] S12, the operating unit obtains the simulated network disk adjustment table from the storage unit, and determines a plurality of simulated network disk terminals that need to be connected according to the simulated network disk adjustment table and the length of the simulated cable, wherein the plurality of simulated network disk terminals are located in the track circuit system;

[0050] S13, the operating unit controls the execution unit to connect to multiple simulated network disk terminals;

[0051] S14, the operating unit detects the connectivity results of the multiple simulated network disk terminals;

[0052] If after detection, the multiple simulated network disk terminals are correctly connected, step S15 is executed;

[0053] S15. Confirm that the configuration of the simulated network disk is complete.

[0054] Among them, the adjustment implementation system can be a hardware device independent of the track circuit system, or a part of the components can be added to the original track circuit structure to form the adjustment implementation system. Of course, the main function of the adjustment implementation system is to adjust the simulated network disk terminal to achieve the actual required simulated cable length. The adjustment implementation system can mainly include an operation unit, a storage unit, an execution unit and a terminal. Among them, the operation unit can input track circuit information and operation instructions. Optionally, the track circuit information can include information such as rail length, track bed resistance, compensation capacitor and number of capacitors; the storage unit can store cable adjustment information (terminal adjustment information), transmitter level adjustment information, receiver main track adjustment information, receiver small track level adjustment information, system adjustment table, cable, rail, tuning unit, matching unit basic electrical parameters and electrical parameter calculation equations, etc., and a calling interface can also be set to facilitate the call of other units in the adjustment implementation system; the execution unit can control the connection or disconnection of the terminal in the track circuit system; the terminal can be used to connect the adjustment implementation system and the track circuit system, wherein different terminals can be used to connect different units in the adjustment implementation system to the track circuit system. A simulated cable can refer to a circuit built with resistors, capacitors, and inductors, so that when the current signal passes through it, it is consistent with the situation passing through a real cable. The length of the simulated cable can be determined according to the length of the real cable, that is, the sum of the real cable length and the simulated cable length is the total cable length. Among them, the total cable length can be a fixed value in the application of track circuit products. Optionally, the total cable length can be 7.5 kilometers or 10 kilometers. The fixed total cable length makes it easy to determine the simulated cable length directly through the real cable length. For example, the total cable length is specified to be 10 kilometers. If the real cable length is 3 kilometers, the simulated cable length is 7 kilometers; if the real cable length is 4 kilometers, the simulated cable length is 6 kilometers. The simulated cable length can be obtained by adjusting the terminals of the simulated network disk in the track circuit system. Such as Figure 2 The cable part of the track circuit system shown in the figure includes a simulated network disk and a real cable. The two ends of the cable part have two terminals for connecting with other parts of the track circuit system. The simulated network disk can include terminals 1 to 10. Of course, the number of terminals of the simulated network disk can be multiple and is not limited to Figure 2 Number of terminals shown.

[0055] In this embodiment, when the operating unit obtains the simulated cable length according to the total cable length and the real cable length, the simulated network disk adjustment table (the table contains different simulated cable lengths and simulated network disk terminals to be connected corresponding to each simulated cable length) can be obtained from the storage unit. The operating unit can determine the simulated network disk terminals to be connected according to the contents of the simulated cable length-terminal in the simulated network disk adjustment table, and connect the simulated network disk terminals through the execution unit. Further, after the simulated network disk terminals are connected, the connectivity of the terminals needs to be detected to avoid safety problems caused by incorrect terminal connections.

[0056] The embodiment of the present application adopts a method for automatically configuring a simulated network disk. In this method, the adjustment implementation system automatically determines multiple simulated network disk terminals that need to be connected according to the length of the simulated cable, and automatically connects them, thereby effectively reducing the error rate of terminal connection. Furthermore, after connecting the terminals, the connection status of the terminals is confirmed by checking twice, which can further reduce the error rate of terminal connection.

[0057] According to another method for automatically configuring a simulated network disk provided by an embodiment of the present application, Figure 1 The step S14 shown may include step 1:

[0058] Step 1: The operating unit detects whether the multiple simulated network disk terminals are connected and whether the multiple simulated network disk terminals that are connected are the multiple simulated network disk terminals that need to be connected. If so, it is determined that the multiple simulated network disk terminals are correctly connected.

[0059] Among them, the operating unit sends a current detection command to the execution unit, and the operating unit obtains the terminal current result returned by the execution unit based on the current detection command, and determines whether multiple simulated network disk terminals are already connected and the multiple connected simulated network disk terminals are multiple simulated network disk terminals that need to be connected according to the terminal current result. Specifically, the operating unit sends a current detection command to the execution unit, and after receiving the current detection command, the execution unit detects whether there is current passing through the connected terminals, and returns the terminal current result to the operating unit. The terminal current result may include two parts: the current passing situation at the connected terminal and the corresponding identification of the connected terminal. The operating unit can determine whether multiple simulated network disk terminals are already connected according to the current passing situation at the connected terminal in the terminal current result; and compare the corresponding identification of the connected terminal with the corresponding identification of the terminal that needs to be connected as determined above, so as to determine that the multiple connected simulated network disk terminals are multiple simulated network disk terminals that need to be connected. This embodiment can effectively reduce the error rate of terminal connection through the double detection of the operating unit.

[0060] According to another method for automatically configuring a simulated network disk provided by an embodiment of the present application, the execution unit may include an electronic switch unit. Figure 1 Before step S13, steps 2 to 4 may also be included:

[0061] Step 2: The operating unit determines the electronic switches corresponding to the multiple simulated network disk terminals that need to be connected through the multiple simulated network disk terminals and the electronic switch protocol;

[0062] Step 3: The operation unit controls the execution unit to connect multiple simulated network disk terminals, including:

[0063] Step 4: The operating unit controls the electronic switches corresponding to the multiple analog network disk terminals that need to be connected to connect the multiple analog network disk terminals.

[0064] Among them, the adjustment implementation system may include multiple electronic switches, and each electronic switch can be connected to the terminal of the simulation network disk in the track circuit system through the terminal of the adjustment implementation system, wherein the connection method between the terminals can be a non-movable connection, such as welding; or a movable connection, such as a switch. In this embodiment, after the operating unit determines the multiple simulation network disk terminals that need to be connected, it can obtain the electronic switch-terminal correspondence table from the storage unit, and the multiple electronic switches corresponding to the multiple simulation network disk terminals that need to be connected can be determined through the table. The operating unit can control the electronic switch to connect the multiple simulation network disk terminals that need to be connected through the execution unit.

[0065] According to another method for automatically configuring a simulated network disk provided by an embodiment of the present application, the method may further include step five and step six:

[0066] Step 5: The operating unit configures the receiving level of the receiver and the transmitting level of the transmitter;

[0067] Step 6: The operating unit detects whether the configuration is correct. If correct, it confirms that the transmission channel of the track circuit system has been configured.

[0068] Among them, first, the operating unit obtains the calculation results of the main rail receiver level, the small rail receiver level and the transmitter level, and obtains the transmitter adjustment information and the receiver adjustment information from the storage unit. Secondly, the operating unit generates the terminal configuration information of the transmitter and the receiver according to the calculation results and the adjustment information, that is, generates multiple terminals that the transmitter needs to be connected and multiple terminals that the receiver needs to be connected. Finally, after the operating unit determines the multiple terminals that need to be connected, it obtains the electronic switch-terminal correspondence table from the storage unit, through which the multiple electronic switches corresponding to the multiple terminals that need to be connected can be determined, and the electronic switches are controlled by the execution unit to connect the multiple terminals that need to be connected, so as to complete the receiving level configuration of the receiver and the sending level configuration of the transmitter.

[0069] Furthermore, after completing the configuration of the receiving level of the receiver and the sending level of the transmitter, it is necessary to detect the connectivity of the terminals. Specifically, the operating unit sends a current detection command to the execution unit. After receiving the current detection command, the execution unit detects whether there is current passing through the connected terminals and returns the terminal current result to the operating unit. The terminal current result may include two parts: the current passing through the connected terminals and the corresponding identification of the connected terminals. The operating unit can determine whether multiple terminals are connected according to the current passing through the connected terminals in the terminal current result; and compare the corresponding identification of the connected terminals with the corresponding identification of the terminals that need to be connected as determined above, so as to determine that the multiple connected terminals are the multiple terminals that need to be connected. When the simulated network disk, the receiving level of the receiver and the sending level of the transmitter are configured, it can be considered that the transmission channel configuration of the track circuit system is completed.

[0070] According to another method for automatically configuring a simulated network disk provided by an embodiment of the present application, the adjustment implementation system may further include a processing unit, and the method may further include step seven and step eight:

[0071] Step 7: The processing unit calculates the electrical parameters of the key nodes of the transmission channel of the track circuit system and detects whether the electrical parameters are correct. If correct, execute step 8;

[0072] Step 8: Confirm that the transmission channel of the track circuit is configured correctly.

[0073] Among them, the processing unit of the adjustment implementation system can perform processing work such as signal calculation, analysis and judgment. When the track circuit system completes the transmission channel configuration, it can determine whether the transmission channel configuration of the track circuit is correct based on the electrical parameters of the key nodes in the transmission channel at this time. Therefore, in this embodiment, the processing unit can generate the calculation results of the electrical parameters of the key nodes of the transmission channel based on the information such as the rail current frequency, rail length, ballast resistance, compensation capacitance value and the number of compensation capacitors input by the operating unit. In addition, the calculation results of the main rail receiver level, the small rail receiver level and the transmitter level in the above-mentioned embodiment are calculated by the processing unit based on the information such as the rail current frequency, rail length, ballast resistance, compensation capacitance value and the number of compensation capacitors input by the operating unit.

[0074] Specifically, when detecting the electrical parameters of the key nodes of the transmission channel, the detection can be divided into two parts: the sending side and the receiving side. In this embodiment, the electrical data of the key nodes of the track circuit transmission channel in the monitoring and diagnosis platform can be called first, and then the electrical data can be compared with the calculation results of the node electrical parameters generated by the above processing unit. If the comparison result is within the error range, it can be considered that the transmission channel configuration of the track circuit is correct. Optionally, the electrical data can include information such as node voltage and node current.

[0075] Further, such as Figure 3 The track circuit system structure shown in FIG. 1 includes sections A, B and C. Specifically, the small track adjustment in section A and the terminals r1 to r4 of the small track adjustment (the number of terminals of the small track adjustment is multiple and not limited to Figure 3 r1, r2, r3 and r4 shown), input terminals r5 and r6 of the receiver corresponding to the small track adjustment, a receiver, a receiving end primary coil L1, a receiving end secondary coil L2, a cable, a matching unit, tuning units BA1 and BA2, an air-core coil SVA, a compensation capacitor C (the number of compensation capacitors is multiple and not limited to Figure 3 The three shown in FIG. 1 ), the transmitter, the output terminal of the transmitter, the primary coil L3 of the transmitter and the secondary coil L4 of the transmitter; the transmitter in section B, the output terminal of the transmitter, the primary coil L5 of the transmitter and the secondary coil L6 of the transmitter. When the transmission channel of section A is configured, the small track adjustment can be used to perform verification between sections. Specifically, section A can receive signals from both section A and section B. After the verification of section A is completed, when the transmitter of section B is started, the receiving channel of section A can be verified again by the small track signal. The repeated verification of sections in this embodiment can improve the reliability of the automatic configuration of the adjustment implementation system.

[0076] In addition, in this embodiment, when the track circuit system simulates the network disk, the receiving level of the receiver and the sending level of the transmitter, in order to avoid the train receiving erroneous information, the configuration signal can be sent through the on-site train control center to facilitate the train to distinguish the configuration signal from the track circuit application signal. Specifically, in order to distinguish the configuration signal from the track circuit application signal and consider the compatibility of the transmission channel of the track circuit, the configuration signal can be adjusted on the basis of the existing track circuit application signal (the track circuit application signal is FSK modulated and can have four basic carrier frequencies: 1700Hz, 2000Hz, 2300Hz and 2600Hz, with a frequency deviation of 11Hz). For example, the carrier frequency of the track circuit application signal is 1700Hz, and two signals of 1711Hz and 1689Hz can be transmitted in the transmission channel. Then, 1711Hz is "0" and 1689Hz is "1". At this time, the signal transmission structure of the configuration signal can be 01010101. After adjustment, the signal transmission structure of the configuration signal can be in the form of 00001111 and the like. Of course, in this embodiment, the configuration signals can be edited in sequence according to different transmission channels to correspond to the track circuits of different sections.

[0077] According to another method for automatically configuring a simulated network disk provided by an embodiment of the present application, the processing unit in step 7 calculates the electrical parameters of key nodes of the transmission channel of the track circuit system, which may specifically include:

[0078] The processing unit calculates the voltages and currents of the receivers, transmitters and matching units in the track circuit system.

[0079] Among them, the key nodes of the transmission channel of the track circuit may include: a receiver input terminal, a cable, a matching unit, a tuning unit, and a transmitter input terminal. In this embodiment, the voltage and current of the key nodes of the transmission channel of the track circuit are mainly calculated to determine whether the transmission channel of the track circuit is configured correctly.

[0080] Specifically, Figure 4 The track circuit system structure shown includes a receiver, an input terminal R 11 and R 12 , two terminals V1 and V2 of the primary coil L7 at the receiving end, and terminals R1, R2 and R3 of the secondary coil L8 at the receiving end (R 11 and R 12 It can be connected to any two of R1, R2 and R3 respectively to adjust the input level of the receiver threshold circuit. The number of terminals of the secondary coil L8 at the receiving end is multiple and not limited to Figure 4R1, R2 and R3 shown in the figure), cables, matching units (the matching units in the track circuit system are mainly used to match the rail impedance and the cable impedance, and the core component is the transformer), tuning units BA1 and BA2, and steel ladle copper lead wire CA (the connecting wire between the tuning unit BA and the rail, which is Figure 4 The black short lines on the left and right sides of the tuning units BA1 and BA2 shown in the figure), the hollow coil SVA, the compensation capacitor C (the number of compensation capacitors is multiple and not limited to Figure 4 The three compensation capacitors C shown in the figure), the transmitter, the output terminals F6 and F7 of the transmitter, the terminals F1, L2 and F3 of the secondary coil L9 of the transmitter (the number of terminals of the secondary coil L9 of the transmitter is multiple and is not limited to Figure 4 F1, L2 and F3) and the primary coil L at the transmitting end 10 The two terminals S1 and S2.

[0081] Among them, the number of turns of the secondary coil at the receiving end is: and The inductance between the primary coils V1 and V2 at the receiving end is The input impedance of the receiving transformer is Where ω is the signal current angular frequency and j is an imaginary number. The minimum value of the input level of the receiver threshold circuit is known to be When the number of turns of the secondary coil at the receiving end is N R When the input voltage between V1 and V2 is: in, is the number of turns between V1 and V2. Since the voltage and current at the beginning of the cable are the voltage and current at the input of the receiver, then

[0082]

[0083]

[0084]

[0085] Among them, V 11 is the voltage at the beginning of the receiving cable, I 11 is the starting current of the receiving cable, Z R1 is the input impedance of the receiving cable end, V V1V2 is the input voltage between V1 and V2, Z cd is the characteristic impedance of the cable, Z V1V2 is the input impedance of the receiving transformer, that is, the input impedance of V1 and V2, γ d is the propagation constant of the cable, l d is the length of the cable at the receiving end, sh represents the hyperbolic sine function, and ch represents the hyperbolic cosine function.

[0086] The voltage and current at the input of the receiving end matching unit can be calculated by the following formula:

[0087]

[0088]

[0089]

[0091] Since the lead-out terminal of the receiving end tuning unit BA2 is connected to the input terminal of the receiving end matching unit, the impedance of the receiving end tuning unit BA2 is equal to the input impedance Z of the receiving end matching unit. R2 If connected in parallel directly, the impedance after parallel connection can be calculated by the following formula:

[0092]

[0093] Among them, Z R3 The impedance of the receiving end tuning unit BA1 and the input impedance of the matching unit Z R2 The impedance after parallel connection, Z R2 is the input impedance of the receiving end matching unit, Z P0 is the pole impedance of the receiving end tuning unit BA1.

[0094] Because Z R3 Connected in series with the ladle copper lead CA, the impedance after series connection can be: Z R4 =Z R3 +Z ca

[0095] Among them, Z R4 Z R3 The impedance after connecting in series with the copper lead wire of the steel ladle, Z ca It is the impedance of the copper lead wire of the steel ladle.

[0096] Therefore, the receiver tuning area (i.e. Figure 4 The total impedance of the area shown (001) is:

[0097]

[0098] Furthermore, the total impedance Z of each unit device at the receiving end JS for:

[0099]

[0100] Among them, Z JIR is the total impedance of the receiving end tuning area, Z R4 Z R3 The impedance after connecting in series with the copper lead wire of the steel ladle, Z1=Z Z0 +Z ca ; Z2=Z SVA +Z ca ; Z3=R V l VI / 2+jωL V l VI / 2, Z4=Z3.

[0101] In the rail section, in order to compensate for the rail loss, a compensation capacitor C can be connected in parallel at a certain distance between the rails. In this embodiment, the primary parameter of the track circuit without compensation capacitor is set to Z V and Y V :

[0102] Z V =R V +jωL V

[0105] Then the secondary parameter Z of the track circuit without compensation capacitor is CV and γV :

[0106]

[0111] After obtaining the impedance of the compensation capacitor in this embodiment, it is necessary to calculate the four-terminal network of the compensation unit. The compensation unit is the area consisting of the compensation capacitor and a small section of rail on the left and right sides of the compensation capacitor. Figure 4 The area 002 shown. The track circuit between the receiving end and the transmitting end in the track circuit system is analyzed based on the compensation capacitor spacing as the basic unit. The basic unit can be composed of three compensation units, that is, three four-terminal networks. The equivalent four-terminal network coefficient after the three four-terminal networks are cascaded is:

[0112]

[0113]
