The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.
[0059] A turnout is a track connection device that allows locomotives and rolling stock to switch from one track to another, and it is also one of the weakest links in the track. It enables trains to switch between different tracks to meet the needs of train scheduling and operation. The main function of a turnout is to guide the wheels of locomotives and rolling stock along the main line or siding. It consists of two stock rails, two switch rails, various connecting parts, and switching machinery. The position of the turnout determines the direction of train travel. However, turnouts cannot rotate independently; their position is controlled by a turnout control system.
[0060] In view of the above situation, this disclosure provides a fully electronic interlocking turnout control system.

[0066] In this exemplary embodiment, a two-out-of-two processor architecture can be used to determine the working state of the switch machine and the position of the turnout. The two-out-of-two processor includes two CPUs, each determining the working state of the switch machine and the position of the turnout respectively. If the results determined by the two CPUs are consistent, the result is considered correct. For example, if CPU1 determines the turnout position to be fixed, and CPU2 also determines the turnout position to be fixed, then the turnout position is confirmed as fixed. If the results determined by the two CPUs are inconsistent, the result is incorrect and needs to be re-determined. In this application, the processor, three-phase power electronic switch, five-way state switching relay, and five-way line connection node can be integrated into a single board structure. The switch machine is connected to the board through the five-way line connection node. The voltage sensor can monitor the voltage between the signal input terminals during the switch machine's rotation and also monitor the voltage between the signal input terminals after the switch machine has completed its rotation. That is, the same voltage sensor circuit can simultaneously monitor the switch machine's rotation state and indication state. The three-phase power electronic switch is used to control the conduction and interruption states of the three-phase circuit. The five-way state switching relay refers to a five-way rotation and indication switching relay.

[0082] Figure 3 In the diagram, Z represents a diode used to indicate the circuit, and R represents a current-limiting resistor. Z and R are installed in the cable and HZ-24. Inside the switch machine, four sets of automatic switches achieve the switching functions of positioning rotation, positioning indication, reverse rotation, and reverse indication, namely 41-42, 13-14, 43-44, 23-24, 25-26, 33-34, 15-16, 25-26, and 35-36 in the diagram. Figure 2 In the diagram, the three sets of coils at the bottom represent the electric motor inside the switch machine. These control the switch machine's positioning or reverse rotation, i.e., controlling the motor's forward or reverse rotation.
[0083] In this application, the processor can receive voltages monitored between a first voltage sensor and a fourth voltage sensor. Specifically, the processor can receive voltage V12 between the first signal input terminal and the second signal input terminal, voltage V13 between the first signal input terminal and the third signal input terminal, voltage V14 between the first signal input terminal and the fourth signal input terminal, and voltage V15 between the first signal input terminal and the fifth signal input terminal.

[0087] In this exemplary embodiment, the processor controls the operation of the switch machine by controlling the rotation of the switch machine through the working states of the three-phase power electronic switches and the five-way state-switching relays. For example, when it is necessary to control the rotation of the switch machine, all three-phase power electronic switches can be closed and turned on. If the switch machine needs to execute a fixed operation command to rotate from the fixed position to the reverse position, the processor with a 2-out-of-2 architecture first controls the first state-switching relay connected to the first line connection node X1, the third state-switching relay connected to the third line connection node X3, and the fourth state-switching relay connected to the fourth line connection node X4 to turn on.

[0096] Based on the first fixed operating power of the switch machine when it rotates from the position to the reverse position, and the second fixed operating power of the switch machine when it rotates from the position to the reverse position, the total fixed operating power of the switch machine when it rotates from the position to the reverse position is determined.
[0097] In this exemplary embodiment, the first fixed operating power Pab = the line current Ib where the B-phase power electronic switch is located * the voltage V13 between the first signal input terminal and the third signal input terminal;
[0098] The second fixed operating power Pac = the line current Ic where the C-phase power electronic switch is located * the voltage V14 between the first signal input terminal and the fourth signal input terminal;
[0099] The total fixed operating power of the switch machine when it rotates from the fixed position to the reverse position = the first fixed operating power Pab + the second fixed operating power Pac.
[0100] In some embodiments, when the switch machine is controlled to rotate from the reverse position to the positioning position, the second current sensor monitors the line current Ib where the B-phase power electronic switch is located, the third current sensor monitors the line current Ic where the C-phase power electronic switch is located, the first voltage sensor monitors the voltage V12 between the first signal input terminal and the second signal input terminal, and the fourth voltage sensor monitors the voltage V15 between the first signal input terminal and the fifth signal input terminal.
[0101] The processor is used to determine the first reverse operation power Pba when the switch machine rotates from the positioning position to the reverse position based on the line current Ib where the B-phase power electronic switch is located and the voltage V12 between the first signal input terminal and the second signal input terminal.
[0102] Based on the line current Ic where the C-phase power electronic switch is located and the voltage V15 between the first signal input terminal and the fifth signal input terminal, the second reverse operation power Pca when the switch machine rotates from the positioning position to the reverse position is determined.
[0103] Based on the first reverse operation power when the switch machine rotates from the fixed position to the reverse position, and the second reverse operation power when the switch machine rotates from the fixed position to the reverse position, the total reverse operation power when the switch machine rotates from the fixed position to the reverse position is determined.
[0104] In this exemplary embodiment, the first reverse operation power Pba = the line current Ib where the B-phase power electronic switch is located * the voltage V12 between the first signal input terminal and the second signal input terminal;
[0105] The second reverse operation power Pca = the line current Ic where the C-phase power electronic switch is located * the voltage V15 between the first signal input terminal and the fifth signal input terminal;
[0106] The total reverse operation power when the switch machine rotates from the stationary position to the reverse position = first reverse operation power Pba + second reverse operation power Pca. Because synchronous sampling is used, voltage and current can be obtained simultaneously. Therefore, the two processors (two-out-of-two) can calculate the phase angle between voltage and current based on algorithms such as Fourier transform, and then calculate data such as active power and reactive power.

[0120] In some embodiments, the current track state of the turnout is determined based on the voltage V12 between the first signal input terminal and the second signal input terminal, the voltage V14 between the first signal input terminal and the fourth signal input terminal, the voltage V13 between the first signal input terminal and the third signal input terminal, and the voltage V15 between the first signal input terminal and the fifth signal input terminal.
[0121] In some embodiments, determining the current track state of the turnout based on the voltage V12 between the first signal input terminal and the second signal input terminal, the voltage V14 between the first signal input terminal and the fourth signal input terminal, the voltage V13 between the first signal input terminal and the third signal input terminal, and the voltage V15 between the first signal input terminal and the fifth signal input terminal includes:
[0122] When the voltage V12 between the first signal input terminal and the second signal input terminal is a full-wave signal, the voltage V14 between the first signal input terminal and the fourth signal input terminal is a positive half-wave signal, the voltage V13 between the first signal input terminal and the third signal input terminal is zero, and the voltage V15 between the first signal input terminal and the fifth signal input terminal is zero, then the current track state of the turnout is determined to be in a fixed position.
[0123] When the voltage V13 between the first signal input terminal and the third signal input terminal is a full-wave signal, the voltage V15 between the first signal input terminal and the fifth signal input terminal is a negative half-wave signal, the voltage V12 between the first signal input terminal and the second signal input terminal is zero, and the voltage V14 between the first signal input terminal and the fourth signal input terminal is zero, then the current track state of the turnout is determined to be reversed.
[0124] In this exemplary embodiment, after the switch machine rotates to its designated position, the 2-out-of-2 processor first closes the fifth state switching relay. When the processor detects that the current output from the current sensor is 0, it considers the fifth state switching relay to be completely closed. Then, the processor switches the four safety switches to the indicated position and begins collecting the voltages sent by the four voltage sensors, with each processor collecting the data independently. The collected data is then compared; if the data matches, the collection is considered correct, and the process proceeds to the data processing flow.
[0125] In this exemplary embodiment, if the voltage waveform between X1 / X2 is a full wave (that is, a complete full wave waveform), the voltage between X1 / X4 is a positive half wave (only the part greater than 0), and there is no voltage on X1 / X3 and X1 / X5, it indicates that the turnout is in position.
[0126] If the voltage waveform between X1 / X3 is a full wave, the voltage between X1 / X5 is a negative half wave, and there is no voltage on X1 / X2 and X1 / X4, then the turnout is in the reverse position.
[0127] If there is no voltage on X1 / X2, X1 / X3, X1 / X4, and X1 / X5, it means that the turnout is in the four-open position.
[0128] If it is any other situation, it indicates that a track mix-up has occurred, and the switch position is still judged as a four-way switch.
[0129] After the judgment is completed, the processor sends the data to the interlocking host or the centralized signal detection system through the communication circuit.
[0130] Figure 5 This is a flowchart illustrating the turnout track status determination according to an exemplary embodiment. For example... Figure 5 As shown, the turnout track status determination process includes:
[0131] Step 50: Begin;
[0132] Step 51: The processor controls the fixed relay to turn off;
[0133] Step 52: The processor detects a current of 0.
[0134] Step 53: The processor controls the four safety relays to the indication position, and then collects four sets of voltages, which are collected by both processors;
[0135] Step 54: Compare whether the voltages collected by the two processors are consistent. If they are inconsistent, the process ends.
[0136] Step 55: If the voltages collected by the two processors are consistent, then if the voltage V12 between the first signal input terminal and the second signal input terminal is a full-wave signal, the voltage V14 between the first signal input terminal and the fourth signal input terminal is a positive half-wave signal, the voltage V13 between the first signal input terminal and the third signal input terminal is zero, and the voltage V15 between the first signal input terminal and the fifth signal input terminal is zero, then the current track state of the turnout is determined to be in the correct position; if the voltage V13 between the first signal input terminal and the third signal input terminal is a full-wave signal, the voltage V15 between the first signal input terminal and the fifth signal input terminal is a negative half-wave signal, the voltage V12 between the first signal input terminal and the second signal input terminal is zero, and the voltage V14 between the first signal input terminal and the fourth signal input terminal is zero, then the current track state of the turnout is determined to be in the reverse position; if all voltages are 0, then the current track state of the turnout is four open, otherwise it is four open and mixed.
[0137] Step 56: Transmit via communication circuit;
[0138] Step 57, End.
[0139] Figure 6 This is a circuit diagram illustrating the rotation control of a switch machine according to an exemplary embodiment. Taking a positioning representation as an example, the circuit principle of its switch machine rotation control is as follows: Figure 6As shown. X1 is the circuit associated with the first line connection node X1, X2 is the circuit associated with the second line connection node X2, and X4 is the circuit associated with the fourth line connection node X4.
[0140] In this application, measuring the voltage between X1 / X2 and X1 / X4 is equivalent to... Figure 6 Remove DBJ and add voltage sensors between X1 and X2, and between X1 and X4. Figure 7 This is an equivalent circuit diagram of a switch machine rotation control circuit according to an exemplary embodiment.
[0141] Figure 7 The switch machine coils U, V, and W are the three coils of the AC motor inside the switch machine. When a single coil is energized, the motor rotates, driving the switch machine to work.
[0142] Assuming the voltage sensor impedance between X1 and X2 is R12 and the voltage sensor impedance between X1 and X4 is R14, then when the transformer output voltage is positive at the bottom and negative at the top, the equivalent circuit can be further equivalent to: Figure 8 :
[0143] Figure 8 The equivalent circuit of the switch machine rotation control circuit shown according to an exemplary embodiment is divided into... Figure 1 Equivalent circuit as follows Figure 8 :
[0144] The voltage V12 between X1 and X2 is
[0145] V12 = Vvariable * ((R12 + RDJ1 + RDJ2) / (R + R12 + RDJ1 + RDJ2));
[0146] V14 = Vvariable * ((RDJ1+RDJ2) / (R+R12+RDJ1+RDJ2)).
[0147] Figure 9 The equivalent circuit of the switch machine rotation control circuit shown according to an exemplary embodiment is divided into... Figure 2 When the transformer output voltage is positive at the top and negative at the bottom, the equivalent circuit is further equivalent to... Figure 9 :
[0148] The resistance between X1 and X2 is equivalent to R12 plus RDJ2 and R14 plus RDJ3 in parallel, denoted as R24. Therefore, the voltage V12 between X1 and X2 is:
[0149] V12 = Vvariable * ((R24 + RDJ1) / (R + R24 + RDJ1));
[0150] The voltage V14 between X1 and X4 is the voltage between P and X2 divided by RDJ2 and R12. The voltage VP between P and X2 is equivalent to the voltage divided by R24 and RDJ1.
[0151] VP = V12 * (R24 / (R24 + RDJ1));
[0152] The voltage between X2 and X4, V24, is equal to VP * (RDJ2 / (R12 + RDJ2)).
[0153] The voltage between X1 and X4 is V14 = V12 - V24.
[0154] In this way, the processor calculates the effective and peak voltage values between X1 / X2 and between X1 / X4 based on the voltage values converted by the synchronous ADC, ensuring they are within the correct voltage range. Simultaneously, the absence of voltage on X1 / X3, X1, and X5 indicates the turnout is in the correct position. Similarly, when the turnout is in the reverse position, calculating the effective and peak voltage values of X1 / X3 and X1 / X5, and determining the absence of voltage on X1 / X2 and X1 / X4, indicates the turnout is in the reverse position. The effective voltage value is calculated using the root mean square (RMS) method. Let the voltage acquisition points after the converter be S1, S2, S3…Sn, then the effective value is:
[0155]
[0156] In some embodiments, when it is necessary to control the switch machine to rotate from the positioning position to the reverse position, the processor is used to control the first state switching relay, the third state switching relay and the fourth state switching relay to be turned on, and the second state switching relay and the fifth state switching relay to be turned off.
[0157] When it is necessary to control the switch machine to rotate from the reverse position to the positioning position, the processor is used to control the first state switching relay, the second state switching relay and the fifth state switching relay to be turned on, and the third state switching relay and the fourth state switching relay to be turned off.
[0158] In this exemplary embodiment, based on the rotation command, when it is a fixed operation command (rotation from position to reverse position), the two-out-of-two processor selects to calculate the voltage between X1 and X3, and the voltage between X1 and X4, and monitors whether there is voltage between X1 and X2, and between X1 and X5. If there is voltage between X1 and X5, it indicates an external wiring misconnection, and the three-phase power electronic switch should be turned off to end the rotation. When a reverse operation command (rotation from position to position) is received, it should select to calculate the voltage between X1 and X2, and the voltage between X1 and X5, and monitor the voltage between X1 and X3, and between X1 and X4. If there is voltage between X1 and X3, and between X1 and X4, it indicates a wiring misconnection, and the three-phase power electronic switch should be turned off to end the rotation. In all embodiments of this application, X1 to X5 are five-wire connection nodes.
[0159] If there is a voltage loss, incorrect amplitude, or large phase difference between X1 and X3, or between X1 and X4, it indicates a circuit malfunction. The solid-state relay should be turned off to stop rotation, and the fault should be reported through the communication circuit.
[0160] If the voltages between X1 and X3, and between X1 and X4, are normal, the circuit is correctly conducting. At this point, calculate the current phase based on the currents in phases B and C. During positioning rotation, phase B leads phase C by 120°; during reverse operation, phase C leads phase B. If the phases are abnormal, it indicates an external wiring error. In this case, the solid-state relay should be turned off to stop the switching. Here, the current sensor circuit is also used for control functions.
[0161] When all three-phase currents are normal, it indicates that all circuits are functioning correctly and the switch machine can rotate normally. If only two of the three current sensors have current, and the currents are equal and much greater than the normal current, it indicates a phase loss. In this case, the control circuit will cut off the circuit to prevent damage to the switch machine and achieve phase loss protection.
[0162] Here, the current sensor is installed on the three-phase power supply and is only used to collect current data when the switch machine is driven. When the current is 0, it indicates that the switch machine has rotated to the correct position.
[0163] The power calculation method here is the two-meter method for calculating three-phase power. That is, assuming phase A is the neutral line, the total power can be obtained by calculating the power of phases B and C. The two-meter method has a lot of theoretical and algorithmic support, which will not be elaborated here.
[0164] When the switch machine is in positioning rotation, the power of phase B is calculated by combining the phase B current with the voltage between X1 and X2, and the power of phase C is calculated by combining the phase C current with the voltage between X1 and X5. The sum of the two power values is the total power.
[0165] When the switch machine is rotating in reverse, the power of phase B is calculated by combining the phase B current with the voltage between X1 and X3, and the power of phase C is calculated by combining the phase C current with the voltage between X1 and X4. The sum of the two power values is the total power.
