It can realize the transfer of trains between different tracks to meet the dispatching and operation needs of trains. The function of the turnout is mainly to guide the wheels of locomotives to travel along the main line or the side line. It consists of two basic rails, two point rails, various connecting parts and switch machinery. The position of the turnout determines the direction of the train. However, the turnout cannot rotate autonomously, and the position of the turnout needs to be controlled by the turnout control system.

[0119] Step 51, end.

[0120] In some embodiments, the current track state of the turnout is determined based on a voltage V12 between the first signal input terminal and the second signal input terminal, a voltage V14 between the first signal input terminal and the fourth signal input terminal, a voltage V13 between the first signal input terminal and the third signal input terminal, and a 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 according to 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, it is determined that the current track state of the turnout is positioning;

[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, it is determined that the current track state of the turnout is in reverse position.

[0124] In this exemplary embodiment, when the switch machine rotates to the right position, the processor of the two-out-of-two architecture first turns off the fifth state switching relay. When the processor detects that the current output by the current sensor is 0, it is considered that the fifth state switching relay has been completely turned off. Then the processor switches the four groups of safety to represent, and starts to collect the voltages sent by the four voltage sensors. The two processors collect them independently. Then the collected data is compared. If the data is consistent, it means that the collection is correct, and then enters the data processing process.

[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 means that the turnout is in position.

[0126] If the voltage waveform between X1 / X3 is full wave, the voltage between X1 / X5 is negative half wave, and there is no voltage on X1 / X2 and X1 / X4, it means that 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 means that mixed tracks have occurred and the switch position is still judged as four open.

[0129] After the judgment is completed, the processor sends the data to the interlocking host or the signal centralized detection system through the communication circuit.

[0130] Figure 5 FIG. 1 is a flow chart of judging the state of a turnout track according to an exemplary embodiment. Figure 5 As shown in FIG. 1 , the turnout track state judgment process includes:

[0131] Step 50, start;

[0132] Step 51, the processor controls the fixed relay to close;

[0133] Step 52: The processor detects that the current is 0;

[0134] Step 53, the processor controls four safety relays to the indicating position, and then collects four groups of voltages, of which two processors collect;

[0135] Step 54, comparing whether the voltages collected by the two processors are consistent, if not, then ending;

[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 it is determined that the current track state of the turnout is positioning; 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 it is determined that the current track state of the turnout is reverse position; if all the voltages are 0, then the current track state of the turnout is four-open, otherwise it is four-open and mixed line;

[0137] Step 56, sending out through the communication circuit;

[0138] Step 57, end.

[0139] Figure 6 FIG. 1 is a circuit diagram of a switch machine rotation control according to an exemplary embodiment. Taking positioning as an example, the circuit diagram of the switch machine rotation control is as follows: Figure 6X1 is a circuit associated with the first line connection node X1, X2 is a circuit associated with the second line connection node X2, and X4 is a 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 The DBJ is removed and voltage sensors are added between X1 and X2, and between X1 and X4. Figure 7 The figure is an equivalent circuit diagram of a switch machine rotation control circuit according to an exemplary embodiment.

[0141] Figure 7 The switch machine coil U, switch machine coil V, and switch machine coil W are three coils of the AC motor inside the switch machine. When a single coil is energized, the motor rotates and drives the switch machine to work.

[0142] Assuming that the voltage sensor impedance between X1 / X2 is R12 and the voltage sensor impedance between X1 / X4 is R14, when the transformer output voltage is positive at the bottom and negative at the top, the equivalent circuit is further equivalent to: Figure 8 :

[0143] Figure 8 The equivalent circuit diagram of the switch machine rotation control circuit according to an exemplary embodiment is shown in FIG. Figure 1 The equivalent circuit is as follows Figure 8 :

[0144] The voltage V12 between X1 / X2 is

[0145] V12 = V change * ((R12 + RDJ1 + RDJ2) / (R + R12 + RDJ1 + RDJ2));

[0146] V14=Vchange*((RDJ1+RDJ2) / (R+R12+RDJ1+RDJ2)).

[0147] Fig. 9 The equivalent circuit diagram of the switch machine rotation control circuit according to an exemplary embodiment is shown in FIG. Figure 2 When the transformer output voltage is positive at the top and negative at the bottom, the equivalent circuit is further equivalent to Fig. 9 :

[0148] The resistance between X1 / X2 is equivalent to R12 plus RDJ2 and R14 plus RDJ3 in parallel, represented by R24, and the voltage V12 between X1 / X2 is:

[0149] V12 = V change * ((R24 + RDJ1) / (R + R24 + RDJ1));

[0150] The voltage V14 between X1 / 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, that is,

[0151] VP = V12 * (R24 / (R24 + RDJ1));

[0152] The voltage between X2 and X4 is V24 = VP*(RDJ2 / (R12+RDJ2));

[0153] The voltage between X1 / X4 is V14=V12-V24.

[0154] In this way, the processor calculates the voltage effective value and peak value between X1 / X2 and the voltage effective value and peak value between X1 / X4 based on the voltage value converted by the synchronous ADC, and they are within the correct voltage range. At the same time, if there is no voltage on X1 / X3, X1 and X5, it can be determined that the turnout is in position. Similarly, when the turnout is in the reverse position, the voltage effective value and peak value of X1 / X3 and X1 / X5 are calculated, and if it is determined that there is no voltage on X1 / X2 and X1 / X4, it can be determined that the turnout is in the reverse position. Among them, the algorithm for the effective value of the voltage adopts the root mean square method. Assuming that the voltage collection points passing through the converter are S1, S2, S3...Sn, respectively, 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 fixed position to reverse position), the two-out-of-two processor chooses 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 means that the external line is mixed, and the three-phase power electronic switch should be closed to end the rotation; when receiving the reverse operation (reverse position to fixed position rotation) command, it should choose to calculate the voltage between X1 and X2, the voltage between X1 and X5, and monitor the voltage between X1 and X3, and the voltage between X1 and X4. If there is voltage between X1 and X3 and between X1 and X4, it means that there is a mixed line, and the three-phase power electronic switch should be closed to end the rotation. Among them, X1~X5 in all embodiments of the present application are five-line circuit connection nodes.

[0159] If there is voltage loss, incorrect amplitude or large phase difference between X1 and X3, and between X1 and X4, it also indicates that the circuit is abnormal. The solid-state relay should be turned off, the rotation should be stopped, and the fault should be reported through the communication circuit.

[0160] If the voltage between X1 and X3, and between X1 and X4 is normal, it means that the circuit is correctly turned on. At this time, the current phase is calculated based on the current of phase B and phase C. When the positioning rotation is performed, the phase of phase B leads the phase of phase C by 120°. When the reverse operation is performed, the phase of phase C leads the phase of phase B. If the phase is abnormal, it means that the external wiring is wrong. At this time, the solid-state relay should be turned off to stop the conversion. Here, the current sensor circuit is also used for control functions.

[0161] When the three-phase current is also normal, it means that all circuits are normal and the switch machine can rotate normally. If only two of the three current sensors have current, and the currents are equal and much larger than the normal current, it means that there is a phase loss, then the control circuit is cut off to avoid the switch machine from being damaged by clicking and to achieve phase loss protection.

[0162] Here, the current sensor is installed on the driving three-phase power and is only used to collect current data when the switch machine is driven. When the current is 0, it means that the switch machine has rotated to the right position.

[0163] The method for calculating power here is the two-table method to calculate the three-phase power, that is, assuming that phase A is the neutral line, the total power can be obtained by calculating the power of phases B and C. The two-table method has a lot of theoretical and algorithmic support, which will not be repeated here.

[0164] When the switch machine is in position and rotating, the B-phase current is used in conjunction with the voltage between X1 / X2 to calculate the B-phase power, and the C-phase current is used in conjunction with the voltage between X1 / X5 to calculate the C-phase power. The sum of the two powers is the total power.

[0165] When the switch machine rotates in reverse, the B-phase current is used in conjunction with the voltage between X1 / X3 to calculate the B-phase power, and the C-phase current is used in conjunction with the voltage between X1 / X4 to calculate the C-phase power. The sum of the two powers is the total power.
