[0023] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0024] In view of the low automation degree of turnout conversion in the simulation test process in the prior art, the embodiment of the present application provides a simulation tool of a five-line turnout switch machine, Figure 1 is a structure schematic view of a simulation tool of a five-line turnout switch machine provided by the embodiment of the present application. Figure 1 As shown in the figure, the simulation tool comprises a trigger component 110, a self-locking component 120, a delay component 130 and a safety component 140.

[0025] The trigger component 110 is connected with the wiring terminal 100 and the self-locking component 120, and the wiring terminal 100 is connected with the turnout board card and the safety component 140; the trigger component 110 is used for receiving an operation instruction sent by the turnout board card based on the wiring terminal 100, and triggering the self-locking component 120 to act based on the operation instruction.

[0026] The self-locking component 120 is connected with the delay component 130 and the safety component 140, and the self-locking component 120 is used for keeping a contact state after action, and the contact state after action is used for triggering the delay component 130 to act.

[0027] The delay component 130 is connected with the safety component 140, and the delay component 130 is used for triggering the safety component 140 to act after reaching a preset delay time length.

[0028] The safety component 140 is used for determining a representation state of a turnout position corresponding to the simulation tool of the five-line turnout switch machine based on a target wiring terminal introduced after action, and sending the representation state to the turnout board card.

[0029] It should be noted that the operation instruction includes a fixed operation instruction and a reverse operation instruction, the fixed operation instruction is used to convert the turnout in the simulation tooling from the reverse position to the fixed position, and the reverse operation instruction is used to convert the turnout in the simulation tooling from the fixed position to the reverse position.

[0030] The representation state of the turnout position includes a fixed table state and a reverse table state, the fixed table state is used to represent the state corresponding to the loop when the turnout is in the fixed position, and the reverse table state is used to represent the state corresponding to the loop when the turnout is in the reverse position.

[0031] The wiring terminal 100 includes a first wiring terminal X1, a second wiring terminal X2, a third wiring terminal X3, a fourth wiring terminal X4 and a fifth wiring terminal X5, and the wiring terminal 100 is connected to the driving end of the turnout board card through a cable. Among them: the first wiring terminal X1 is used as a common terminal, the second wiring terminal X2 to the fifth wiring terminal X5 are connected to the driving end of the turnout board card, the second wiring terminal X2 and the fifth wiring terminal X5 are used to receive the fixed operation instruction sent by the turnout board card, and the third wiring terminal X3 and the fourth wiring terminal X4 are used to receive the reverse operation instruction sent by the turnout board card.

[0032] In addition, when the operation instruction is the fixed operation instruction, the target wiring terminal of the safety component 140 after the action introduces the circuit to be the first wiring terminal X1, the second wiring terminal X2 and the fourth wiring terminal X4, and when the operation instruction is the reverse operation instruction, the target wiring terminal of the safety component 140 after the action introduces the circuit to be the first wiring terminal X1, the third wiring terminal X3 and the fifth wiring terminal X5.

[0033] After the user sends an operation instruction through the turnout card, the simulation tool can receive the operation instruction through the target terminal. The operation instruction can control the trigger component 110 to be powered on. After the trigger component 110 is powered on, the control operation instruction corresponding to the first target contact is attracted, and after the first target contact is attracted, the coil in the self-locking component 120 is powered on, and the second target contact in the self-locking component 120 is attracted, and the second target contact is controlled to remain in the attracted state. A preset delay time is set in the delay component 130. When the second target contact in the self-locking component 120 is attracted, the timing starts, and after the preset delay time is reached, the third target contact is attracted by the delay component 130, thereby controlling the safety component 140 to act. The simulation tool simulates the simulation action process corresponding to the operation instruction within the preset delay time. The simulation action starts when the second target contact in the self-locking component 120 is attracted, and ends after the preset delay time is reached. After the simulation action is completed, the safety component 140 forms an operation instruction corresponding to the representation loop through the target terminal corresponding to the operation instruction, to determine the representation state of the turnout position corresponding to the simulation tool, so that the turnout card can automatically obtain the representation state of the turnout position corresponding to the simulation tool after the simulation action is performed, without the need for manual operation of the representation switch, thereby improving the automation degree of the turnout conversion in the simulation test process, and further improving the simulation test efficiency.

[0034] It should be noted that the simulation tool further includes a representation power supply, at least one fan and a fan power supply. The representation power supply is used to power the representation circuit, the fan power supply is used to power each fan, and each fan is used to dissipate heat for the simulation tool to prevent the temperature in the simulation tool from being too high to affect the operation of the device. In addition, before the simulation tool performs simulation testing, it can be checked whether the circuit wiring is correct and whether the circuit connection is fixed. Then, the representation power supply and the fan power supply are powered on. After being powered on, the simulation tool is in a default state by default, that is, the turnout in the simulation tool is in a default position.

[0035] Further, the trigger component 110 includes a reverse operation 380V relay K1 and a fixed operation 380V relay K2, wherein: The reverse operation 380V relay K1 is connected to the third terminal X3 and the fourth terminal X4 in the terminal 100, and the reverse operation self-locking relay K3 in the self-locking component 120; the reverse operation 380V relay K1 is used to generate a first reverse operation signal corresponding to the reverse operation self-locking relay K3 based on the reverse operation instruction sent by the third terminal X3 and the fourth terminal X4; The fixed operation 380V relay K2 is connected with the second terminal X2 and the fifth terminal X5 in the terminal 100, and the fixed operation self-locking relay K4 in the self-locking assembly 120; the fixed operation 380V relay K2 is used for generating the first fixed operation signal of the fixed operation self-locking relay K4 based on the fixed operation instruction sent by the second terminal X2 and the fifth terminal X5.

[0036] For example, Figure 2 is a structure schematic diagram of the simulation tool of the five-wire turnout switch machine provided by the embodiment of the application, as shown in Figure 2 As shown in the figure, after the reverse operation instruction is sent through the third terminal X3 and the fourth terminal X4 at the driving end of the turnout plate card, the contact 5 and the contact 9 in the reverse operation 380V relay K1 are attracted, and the contact 8 and the contact 12 are attracted, that is, the first target contact corresponding to the reverse operation instruction is the contact 5, the contact 9, the contact 8 and the contact 12 of the reverse operation 380V relay K1. Since the contact 8 of the reverse operation 380V relay K1 is connected with the contact 13 of the reverse operation self-locking relay K3 in the self-locking assembly 120, after the contact 8 and the contact 12 are attracted, the first reverse operation signal of the reverse operation self-locking relay K3 can be generated, and the first reverse operation signal can trigger the reverse operation self-locking relay K3 to act.

[0037] After the fixed operation instruction is sent through the second terminal X2 and the fifth terminal X5 at the driving end of the turnout plate card, the contact 5 and the contact 9 in the fixed operation 380V relay K2 are attracted, and the contact 8 and the contact 12 are attracted, that is, the first target contact corresponding to the fixed operation instruction is the contact 5, the contact 9, the contact 8 and the contact 12 of the fixed operation 380V relay K2. Since the contact 8 of the fixed operation 380V relay K2 is connected with the contact 13 of the fixed operation self-locking relay K4 in the self-locking assembly 120, after the contact 8 and the contact 12 are attracted, the first fixed operation signal of the fixed operation self-locking relay K4 can be generated, and the first fixed operation signal can trigger the fixed operation self-locking relay K4 to act.

[0038] In the embodiment of the application, the driving voltage of the two relays in the triggering assembly 110 is 380V alternating current, and during the test process, since manual intervention is not required, the risk brought by strong current 380V to the operator can be avoided, and the safety and reliability of the simulation test process are improved.

[0039] Further, as shown in the figure, Figure 2 The triggering assembly 110 further includes a reverse operation indicating lamp D2 and a fixed operation indicating lamp D1, wherein: The reverse operation indicating lamp D2 is connected with the display contact of the reverse operation 380V relay K1; the reverse operation 380V relay K1 is used for lighting the reverse operation indicating lamp D2 when the reverse operation instruction is received; The fixed operation indicating lamp D1 is connected to the display contact of the fixed operation 380V relay K2; the fixed operation 380V relay K2 is used for lighting the fixed operation indicating lamp D1 in the case of receiving the fixed operation instruction.

[0040] For example, in the reverse operation 380V relay K1, the contact 5 is used as a display contact. After the contact 9 and the contact 5 in the reverse operation 380V relay K1 are attracted, the reverse operation indicating lamp D2 connected to the contact 5 is lit.

[0041] In the fixed operation 380V relay K2, the contact 5 is used as a display contact. After the contact 9 and the contact 5 in the fixed operation 380V relay K2 are attracted, the fixed operation indicating lamp D1 connected to the contact 5 is lit.

[0042] It should be noted that the light-emitting colors of the reverse operation indicating lamp D2 and the fixed operation indicating lamp D1 can be yellow, red, green, etc., and the embodiments of the present application do not limit this, as long as the light-emitting color of the reverse operation indicating lamp D2 is different from that of the fixed operation indicating lamp D1, which is convenient for the operator to clearly understand the current simulation test process.

[0043] Further, the reverse operation self-locking relay K3 is used for maintaining the closed state of the reverse operation self-locking contact based on the first reverse operation signal, and generating a second reverse operation signal; The fixed operation self-locking relay K4 is used for maintaining the closed state of the fixed operation self-locking contact based on the first fixed operation signal, and generating a second fixed operation signal.

[0044] For example, as shown in Figure 2 The second target contact in the self-locking assembly 120 includes the contact 8 and the contact 12 in the reverse operation self-locking relay K3, and the contact 8 and the contact 12 in the fixed operation self-locking relay K4, and the contact 8 and the contact 12 in the reverse operation self-locking relay K3 are used as the corresponding reverse operation self-locking contact of the reverse operation self-locking relay K3, and the contact 8 and the contact 12 in the fixed operation self-locking relay K4 are used as the corresponding fixed operation self-locking contact of the fixed operation self-locking relay K4.

[0045] In the reverse operation self-locking relay K3, after receiving the first reverse operation signal, the first reverse operation signal can trigger the coil in the reverse operation self-locking relay K3 to be energized, so that the contact 8 and the contact 12 are attracted. The attraction state of the contact 8 and the contact 12 is independent, that is, as long as there is no other external operation to change the attraction state of the two contacts, the contact 8 and the contact 12 will remain in the attracted state, so that the reverse operation self-locking relay K3 can realize the self-locking function of the reverse operation self-locking relay K3 without a continuous activation signal, thereby continuously generating a second reverse operation signal.

[0046] In the fixed operation self-holding relay K4, the contact 13 receives the first fixed operation signal, which can trigger the coil of the fixed operation self-holding relay K4 to be energized, so that the contact 8 and the contact 12 are attracted. And the contact 8 and the contact 12 remain in the attracted state, so that the fixed operation self-holding relay K4 can realize the self-holding function of the fixed operation self-holding relay K4 without a continuous activation signal, thereby continuously generating the second fixed operation signal.

[0047] Further, the delay component 130 includes a reverse operation delay relay S2 and a fixed operation delay relay S1, wherein: The reverse operation delay relay S2 connects the reverse operation self-holding contact of the reverse operation self-holding relay K3 and the safety component 140; the reverse operation delay relay S2 is used to generate the first reverse table signal corresponding to the safety component 140 based on the second reverse operation signal when the preset delay duration is reached; The fixed operation delay relay S1 connects the fixed operation self-holding contact of the fixed operation self-holding relay K4 and the safety component 140; the fixed operation delay relay S1 is used to generate the first fixed table signal corresponding to the safety component 140 based on the second fixed operation signal when the preset delay duration is reached.

[0048] It should be noted that the reverse operation delay relay S2 and the fixed operation delay relay S1 are both pre-set with a preset delay duration, and the preset delay duration corresponding to the reverse operation delay relay S2 and the preset delay duration corresponding to the fixed operation delay relay S1 can be the same or different, which can be set according to the actual duration of the respective simulation action.

[0049] For example, as Figure 2 shown, when the first reverse operation signal activates the reverse operation self-holding relay K3, it also triggers the timer in the reverse operation delay relay S2 to start timing. During the process that the timer does not reach the preset delay duration, the contacts in the reverse operation delay relay S2 maintain the default state, that is, the coil in the reverse operation delay relay S2 is in a de-energized state, and the contact 8 and the contact 12 are in a disconnected state. After the timer reaches the preset delay duration, the second reverse operation signal can trigger the coil of the reverse operation delay relay S2 to be energized, so that the contact 8 and the contact 12 in the reverse operation delay relay S2 are attracted, and the first reverse table signal corresponding to the safety component 140 is generated. The contact 8 and the contact 12 are the third target contacts in the reverse operation delay relay S2.

[0050] When the first fixed operation signal activates the fixed operation self-locking relay K4, the timer in the fixed operation delay relay S1 is triggered to start timing. During the preset delay time, the contacts in the fixed operation delay relay S1 maintain the default state, i.e., the coil in the fixed operation delay relay S1 is in a power-off state, and the contacts 8 and 12 are in an open state. After the timer reaches the preset delay time, the second fixed operation signal can trigger the coil in the fixed operation delay relay S1 to be powered on, so that the contacts 8 and 12 in the fixed operation delay relay S1 are attracted, and the first fixed table signal corresponding to the safety assembly 140 is generated. The contacts 8 and 12 are the third target contacts in the fixed operation delay relay S1.

[0051] Further, as shown in Figure 2 The safety assembly 140 includes a first safety relay KM1, a second safety relay KM2, a third safety relay KM3, and a fourth safety relay KM4. The first safety relay KM1 is connected to the reverse operation delay relay S2, a second terminal X2, and a third terminal X3. The second safety relay KM2 is connected to the fixed operation self-locking relay K4, the reverse operation delay relay S2, a fourth terminal X4, and a fifth terminal X5. The third safety relay KM3 is connected to the fixed operation delay relay S1 and the reverse operation self-locking relay K3. The fourth safety relay KM4 is connected to the first terminal X1. The first safety relay KM1 and the second safety relay KM2 are used to determine the reverse table state of the turnout position based on the first reverse table signal. The first safety relay KM1, the second safety relay KM2, and the third safety relay KM3 are used to determine the fixed table state of the turnout position based on the first fixed table signal.

[0052] For example, after the reverse operation delay relay S2 reaches the preset delay time, the first reverse table signal can trigger the first safety relay KM1 and the second safety relay KM2 to act, i.e., trigger the contacts 1 and 2 in the first safety relay KM1 to be attracted, so that the third terminal X3 is introduced into the circuit, and trigger the contacts 3 and 4 in the second safety relay KM2 to be attracted, so that the fifth terminal X5 is introduced into the circuit. The third terminal X3, the fifth terminal X5, and the first terminal X1 as a common terminal constitute a reverse table indicating loop, indicating that the turnout position is in a reverse table state. Without manual operation of the indicating switch, the turnout plate can automatically collect that the turnout position is in a reverse table state.

[0053] When the fixed delay relay S1 reaches the preset delay duration, the first fixed table signal triggers the third safety relay KM3 to act, i.e., the contact R1 and the contact R2 in the third safety relay KM3 are disconnected, the anti-operation self-locking relay K3 is actuated, and then the anti-table indicating circuit is disconnected. After that, the contact R3 and the contact R4 in the second safety relay KM2 are in a normally closed state, i.e., the fourth terminal X4 is introduced into the circuit by default, and the contact R1 and the contact R2 in the first safety relay KM1 are in a normally closed state, i.e., the second terminal X2 is introduced into the circuit by default. The second terminal X2, the fourth terminal X4 and the first terminal X1 as a common terminal constitute a fixed table indicating circuit, indicating that the turnout position is in a fixed table state. Without manual operation of the indicating switch, the turnout board card can automatically collect that the turnout position is in a fixed table state.

[0054] It should be noted that the first safety relay KM1 and the second safety relay KM2 belong to two-open and two-closed safety relays, and the third safety relay KM3 and the fourth safety relay KM4 belong to one-open and one-closed safety relays. After the simulation tool is powered on, the turnout position in the simulation tool defaults to a fixed table state. At this time, the contact R3 and the contact R4 in the second safety relay KM2 are attracted, indicating that the fourth terminal X4 is introduced into the circuit, the contact R1 and the contact R2 in the first safety relay KM1 are attracted, indicating that the second terminal X2 is introduced into the circuit, and the contact R1 and the contact R2 of the fourth safety relay KM4 are attracted, indicating that the first terminal X1 is introduced into the circuit, i.e., the first terminal X1, the second terminal X2 and the fourth terminal X4 constitute a fixed table indicating circuit, and at this time, the turnout board card can collect that the turnout position is in a fixed table state.

[0055] Further, as shown in Figure 2 The safety assembly 140 further includes an anti-table indicating lamp D4, a fixed table indicating lamp D3, a coil resistance circuit and a four-open switch SW, wherein: The anti-table indicating lamp D4 is connected to the first safety relay KM1 and the coil resistance circuit; the first safety relay KM1 is configured to light the anti-table indicating lamp D4 based on the anti-table state; The fixed table indicating lamp D3 is connected to the first safety relay KM1 and the coil resistance circuit; the first safety relay KM1 is further configured to light the fixed table indicating lamp D3 based on the fixed table state; The coil resistance circuit is further connected to the second safety relay KM2 and the fourth safety relay KM4; The four-open switch SW is connected to the fourth safety relay KM4, and the on-off state of the four-open switch SW is configured to control the working state of the simulation tool of the five-wire turnout switch machine.

[0056] For example, after the contact 1 and the contact 2 in the first safety relay KM1 are attracted, the reverse indication lamp D4 connected with the contact 2 of the first safety relay KM1 is lighted, further indicating that the switch position is in the reverse state.

[0057] After the reverse indication circuit is disconnected, the contact R2 and the contact R1 in the first safety relay KM1 are in the normally closed state, at this time, the fixed indication lamp D3 connected with the contact R2 is lighted, further indicating that the switch position is in the fixed state.

[0058] In addition, the coil resistances R1, R2 and R3 in the coil resistance circuit play a role in driving current limiting, the resistance R4 serves as a current limiting resistance in the indication circuit, and the fixed indication circuit and the reverse indication circuit share the same current limiting resistance.
