All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. In the present application, the embodiments and features of the embodiments may be arbitrarily combined with each other without conflict.

Fig. 2 is a schematic structural diagram of a switch control system according to an embodiment of the present application, and as shown in fig. 2, a switch control system 100 according to an embodiment of the present application includes: an interlocking device 101, an interface circuit 103 and a turnout control device 102; wherein, one end of the interface circuit 103 is connected with the interlocking device 101; the other end of the interface circuit 103 is connected with the turnout control equipment 102; the interface circuit 103 comprises at least two forward paths;

as can be seen from fig. 1 and 2, unlike the conventional switch control technology, the switch control system 100 according to the embodiment of the present application adds the interface circuit 103 between the interlock device 101 and the switch control device 102. It can be seen that, in the switch control system 100 in the embodiment of the present application, the interface circuit 103 controls the communication between the interlock device 101 and the switch control device 102, and different forward paths in the interface circuit 103 separately transmit different types of control commands, so that each control command does not interfere with each other, thereby avoiding the influence on the normal operation of the whole switch control system when a circuit fails, and facilitating the realization of safe and stable control over the switch operation according to various conditions occurring in the system.

In terms of the function, the user can select the specific part,

the interlocking device 101 is configured to generate a control command, and control a forward target path of the at least two forward paths to be in an open state according to a type of the control command;

the interface circuit 103 is configured to transmit the control command from the interlock device to the turnout control device by using a forward target path in an open state;

and the turnout control equipment 102 is used for controlling the turnout to perform turnout operation corresponding to the control command.

When a control command generated by the interlock device 101 needs to be sent to the switch control device 102, a forward target path of the at least two forward paths needs to be opened according to the type of the control command, so that the control command cannot be directly transmitted to the switch control device 102, but reaches the switch control device 102 when the forward target path is opened, and thus, the state of the forward path in the interface circuit 103 determines whether to open or cut off the communication between the interlock device 101 and the switch control device 102, and does not need to artificially monitor the switch control system 100, thereby ensuring that the switch control system 100 can safely and stably control switch operation, reducing the occurrence rate of potential safety hazards, and increasing the safety degree of train running.

Specifically, the type of the control command generated by the interlock device 101 represents information for controlling what kind of operation is performed by the switch, and is control information, and the control command is generated in an application scene in which the switch is required to be operated to perform an action; the interlock device 101 sends the generated control command to the interface circuit 103, and controls the forward target path that can be opened according to the type of the control command in the interface circuit 103 to open, so as to transmit control information to the switch control device 102, and inform the switch control device 102 to control the switch to execute the relevant operation according to the control information. Obviously, the transmission direction of the forward path is a direction in which the interlock device 101 transmits the control information to the switch control device 102 through the interface circuit 103, the forward target path is one of the at least two forward paths that can be opened according to the control information, and the interface circuit 103 is equivalent to an interface that controls whether to perform communication between the interlock device 101 and the switch control device 102, and has a function of transmitting the control command on the forward target path that is opened according to the type of the control command.

The method controls the opening of the forward target passage in at least two forward passages according to the type of the control command so as to transmit the control command to the turnout control equipment 102, is a mode of controlling whether the passage is opened or not by the equipment so as to transmit a signal (control command), can accurately control the turnout operation, and solves the technical problem that the turnout operation is not safe and stable enough due to manual control of opening or closing the interlocking equipment 101 and the turnout control equipment 102. In addition, the interlock device 101 sends a control command, and transmits the control command to the switch control device 102 by opening the forward path in the interface circuit 103, instead of directly transmitting the control command to the switch control device 102, so that the switch control system 100 has certain capability of detecting self faults and protecting the safe operation of the system, and the accuracy and the safety of controlling the switch operation are improved.

The switch control system that this application embodiment provided can be applied to any track communication and realize the occasion of switch control, like the switch control occasion of magnetic levitation switch, the switch control occasion of subway and the switch control occasion of high-speed railway. That is, the interface circuit 103 provided in the embodiment of the present application is suitable for controlling switches of different types. As an optimal mode, the magnetic suspension turnout control system can be applied to magnetic suspension turnout occasions and can realize effective control on the magnetic suspension turnout.

In an embodiment of the present application, the at least two forward paths include a first forward path and a second forward path;

here, the first forward path and the second forward path are opened as forward target paths according to different types of control commands, and the control commands are transmitted to the turnout control device 102; the first forward path and the second forward path are two different forward paths;

in the specific implementation function, the system is provided with the following functions,

the interlocking device 101 is configured to control the first forward path to be in an open state when the control command represents a command type for performing a positioning operation on the turnout; under the condition that the control command is characterized as a command type for carrying out the reversal operation on the turnout, controlling the second forward path to be in an open state;

here, the interlock device 101 has a control effect on which forward path is opened as a forward target path in the interface circuit 103, specifically, the control information represented in the control command stimulates the forward target path to be opened;

the interface circuit 103 is configured to transmit a control command, which is characterized by a command type for performing a positioning operation on a switch, to the switch control device 102 by using a first forward path; or, transmitting a control command of a command type characterized by performing a bit reversal operation on the turnout to the turnout control device 102 by using a second forward path;

the control command is characterized as a positioning control command in a positioning operation type, and is characterized as a reverse control command in a reverse operation type, the forward target access is controlled to be opened according to the information characterized by the control command, and when the control command is the positioning control command, the first forward access is opened, and the second forward access is closed; when the control command is a flip control command, the second forward path is open and the first forward path is closed, so that a control command of one type can only be transmitted on the forward target path on which it is open. The interface circuit 103 is used for transmitting a control command on the opened forward target path, and cannot control the opening and closing of the forward target path per se, but at least two forward paths contained in the interface circuit open the forward target path under the excitation of the control command;

the turnout control equipment 102 is used for controlling the turnout to perform positioning operation under the condition that the control command is a positioning control command; or, under the condition that the control command is a reverse control command, controlling the turnout to perform reverse operation;

here, the positioning control command activates a first forward path to be opened, and is transmitted to the switch control device 102 through the first forward path, and the switch control device 102 controls the switch to execute the positioning operation according to the type of control command; or the reversal control command excites a second forward path to be opened, the second forward path is transmitted to the turnout control equipment 102 through the second forward path, and the turnout control equipment 102 controls the turnout to execute reversal operation according to the type of control command; the control commands for controlling the opening types of the interlocking devices 101 are transmitted through different forward paths, so that the control commands of the interlocking devices 101 can accurately reach the turnout control device 102, and the definite division of labor of the interface circuit 103 in the process of transmitting the control commands is embodied.

Here, the switch control device 102 controls the switch operation according to the type of the control command, and the control of the switch operation by the interlock device 101 is realized.

In the above scheme, a single turnout is taken as an example and includes a first path and a second path, the positioning operation refers to switching the turnout from the first path to the second path, and the flipping operation refers to switching the turnout from the second path to the first path; the first path and the second path are relative concepts, and can be mutually converted in practical application. When the control command is characterized as a command type of positioning operation, opening a first forward path, and transmitting the control command of positioning operation to the turnout control device 102 to control the turnout to be switched from a first path to a second path; when the control command is characterized as a command type of the flip operation, a second forward path is opened, and the control command of the flip operation is transmitted to the turnout control device 102 to control the turnout to switch from the second path to the first path. In the transmission of these two control commands, since the generated control command is of one command type and is guaranteed to be transmitted by the openable forward target path, the problem that one forward path needs to transmit multiple control commands does not occur, the complexity of the interface circuit 103 can be reduced, and the switch control system 100 has strict control logic.

In the above solution, in addition to the situation of the forward path for the interlock device 101 to transmit the control command to the switch control device 102, the switch control system 100 provided in the embodiment of the present application may further implement a reverse path for the switch control device 102 to transmit the control result to the interlock device 101, and the following is specifically stated:

the interface circuit further comprises at least two reverse paths;

here, the at least two reverse paths are used for the switch control device 102 to transmit information to the interlock device 101;

the turnout control equipment 102 is used for obtaining a control result for controlling turnout operation; controlling a reverse target passage in the at least two reverse passages to be in an open state according to the type of the control result;

the interface circuit 103 is configured to transmit the control result from the turnout control device to the interlock device 101 by using a reverse target path in an on state;

the interlocking device 101 is configured to receive and output the control result.

Therefore, according to the turnout control system 100 provided by the embodiment of the application, the interface circuit 103 is additionally arranged between the interlocking device 101 and the turnout control device 102, and the turnout control device 102 can be further used for opening the corresponding reverse target access in the at least two reverse accesses according to the type of the control result when the control result obtained by the turnout control device 102 according to the turnout operation condition needs to be sent to the interlocking device 101, so that the interlocking device 101 can timely know the turnout operation condition, the turnout control system 100 can safely and stably control the turnout operation, the occurrence rate of potential safety hazards is reduced, and the safety degree of train running is increased.

Specifically, the type of the control result obtained by the switch control device 102 represents information of a situation where the switch executes the control command, and is control information, and a type of control result is generated for different operation situations of the switch executing the control command in an application scene; the switch control device 102 sends the obtained control result, controls a reverse target path of the at least two reverse paths in the interface circuit 103 to open, and sends the control result to the interlock device 101. It is understood by those skilled in the art that the forward path and the reverse path are a relative concept and are not described in detail herein. The interface circuit 103 corresponds to an interface between the interlock device 101 and the switch control device 102, and has a function of transmitting a control result on a corresponding reverse path that is opened according to the control result.

In an embodiment of the present application, the at least two reversal paths include a first reversal path and a second reversal path;

Thus, a control result can only be transmitted on the target reverse path that it can open;

in terms of the realization of the function,

the switch control device 102 is further configured to control the first reverse path to be in an open state when the control result is characterized as a successful result of the positioning operation on the switch; or, under the condition that the control result is characterized as a successful result of the inversion operation of the turnout, controlling the second reverse path to be in an open state;

the interface circuit 103 is configured to transmit a successful result, which is characterized by a switch location operation, from the switch control device 102 to the interlock device 101 using the first reverse path in the on state; or, the second reverse path for utilizing the on state is used for transmitting the successful result which is characterized by carrying out the reversal operation on the turnout to the interlocking device 101 by the turnout control device;

here, the interface circuit 103 is configured to transmit the control result at this time on the opened reverse target path, and cannot control the opening or the disconnection of the reverse target path by itself, but at least two forward paths included in the interface circuit open the reverse target path under the excitation of the control result;

accordingly, the method can be used for solving the problems that,

the interlocking device 101 is used for receiving and outputting a successful result which is characterized in that the positioning operation is carried out on the turnout or a successful result which is characterized in that the inversion operation is carried out on the turnout;

the interlock device 101 receives and outputs a successful result characterized as a positioning operation on the switch through the first reverse path; alternatively, a successful result, characterized as a toggle operation on the switch, is received and output through the second reverse path.

Due to the reverse path in the interface circuit 103, the interlock device 101 not only can generate and send a control command, but also can receive a control result of controlling the turnout operation and obtain the feedback of the sent control command, so that the control logic in the whole turnout control operation is more perfect, and the turnout operation can be further ensured to be completed under a safe and strict working environment.

Further, the at least two reversal paths include a third reversal path; the control result also comprises a control result which is characterized in that the positioning operation or the inversion operation of the turnout fails;

in terms of the realization of the function,

in the case where the third reverse path is in the on state, the interface circuit 103 transmits a control result, which is characterized by a failure of the positioning operation or the flip operation, to the interlock device 101 using the third reverse path;

the switch control device 102 is further configured to control the third reverse path to be in an open state when the control result is characterized as a control result of failure of positioning operation or flipping operation;

the interface circuit 103 is configured to transmit a control result, which is characterized by a failure of a positioning operation or a flipping operation, from the turnout control device 102 to the interlock device 101 by using the third reverse path in the on state;

accordingly, the method can be used for solving the problems that,

the interlocking device 101 is configured to receive and output a control result that is characterized by a failure of a positioning operation or a flipping operation.

In the above scheme, under the condition that the operation of executing the control command by the turnout fails, the turnout control device 102 feeds back the type of control result to the interlocking device 101 through the interface circuit 103, so that the interlocking device 101 can timely know that the turnout operation is wrong, the monitoring of the turnout operation condition is realized through strict and comprehensive operation logic, and the driving safety is further ensured.

In an embodiment of the present application, the interface circuit further includes at least two latch circuits;

the interface circuit 103 is configured to lock the turnout with the target locking circuit in the open state.

Through under different control result types, the turnout is locked by the turnout control equipment 102 and the interface circuit 103 respectively, so that the turnout can be locked in time when the turnout executes a control command and fails, the situation that the failure which can not be estimated occurs is prevented, corresponding measures are taken for the turnout after the operation fails, the turnout is locked in time when the turnout executes the control command successfully is also ensured, and potential safety hazards such as movement of the turnout when a train passes through later are prevented.

Wherein the at least two latching circuits comprise a first latching circuit and a second latching circuit;

the at least two locking circuits can lock the turnout under different control result types;

or, the switch control device 102 is configured to control the second locking circuit to be in an open state when the control result is characterized as a result of switch operation failure; correspondingly, the interface circuit is used for locking the turnout by using the second locking circuit in an open state.

Here, the switch control device 102 obtains a control result, activates a target locking circuit to lock the switch according to the type of the control result, and the interface circuit 103 locks the switch by using the opened target locking circuit so that the switch cannot move;

specifically, in order to activate the target locking circuit, the switch control device 102 is configured to, if the control result is characterized as a successful switch operation result, use a first power supply, where the first power supply is configured to supply power to the first locking circuit, and the first locking circuit to be supplied with power is in an open state;

and the switch control device 102 is configured to, when the control result is characterized as a switch operation failure result, use a second power supply, where the second power supply is configured to supply power to the second locking circuit, and the second locking circuit to be supplied with power is in an open state.

The specific operation principle of the circuit structures in fig. 5-8 in the application scenario in fig. 9 is described in detail with reference to the following related description.

Next, the operation principle of the switch control system 400 will be described in detail by taking a single switch as an example, in conjunction with the application scenario of fig. 9 and the cooperation of the circuit structures in fig. 5 to 8:

first, the interlock device 101 generates a control command and sends the control command to the control mode switching circuit 104 and the interface circuit 103, respectively.

The control mode switching circuit 104 controls the turnout control system to work in a centralized state mode according to the control command of the interlocking device 101, namely the working mode of the interlocking device 101 for controlling turnout operation, and sends a corresponding command to the interface circuit 103, controls all centralized state relays JZZJ in fig. 7 to suck (close), and selects a reasonable working mode according to the working condition of the turnout to control the turnout control system.

When the control command is a positioning control command, a positioning relay DJ in

lines

71 and 73 in the figure 7 receives the positioning control command of the interlocking device 101 through a relay interface, excitation is closed, and the control command and a cut-off relay QDJ are powered by the circuit in the figure 5 and are in a suck-up state; at this time, the

lines

71 and 73 constitute a first forward path.

Specifically, the operating state of the disconnecting relay QDJ is determined by the switch disconnecting circuit in fig. 5, and the specific operating principle is as follows:

when the interlock device 101 issues a control command to the interface circuit 103, in fig. 5, the third power supply supplies power to the switch interrupting circuit, positions the positioning indicating relay DBJ, the flip indicating relay FBJ, the timeout interrupting relay CSQDJ, and the unmoved interrupting relay WDQDJ to suck up, and interrupts the shunt and the unmoved shunt to form a passage, and supplies power to and excites the output interrupting positioner QDJ to suck up the interrupting positioner QDJ.

Further, setting a first preset time for the unmoved tripping relay WDQDJ, wherein the unmoved tripping relay WDQDJ automatically falls down after the first preset time is exceeded; and setting a second preset time for the overtime cut-off relay CSQDJ, wherein the overtime cut-off relay CSQDJ automatically falls down after the second preset time is exceeded.

In general, the operation indication time of the switch is about 4.5 seconds (i.e., it takes about 15 seconds to start the positioning operation within 4.5 seconds) and to complete the positioning operation, and in this embodiment, a first preset time for maintaining the pull-up state after the excitation of the unmoved cut-off relay WDQDJ may be 7 seconds, and a second preset time for maintaining the pull-up state after the excitation of the overtime cut-off relay CSQDJ may be 30 seconds.

If the switch control cabinet fails to control the switch to perform the positioning operation, namely, the time that the switch does not start to perform the positioning operation exceeds 7 seconds, the WDQDJ is not switched from the sucking-up state to the falling-down state; and, if the positioning operation is not completed within 30 seconds of the switch, the overtime cut-off relay CSQDJ also switches from the suck-up state to the drop-down state, and the overtime cut-off shunt and the unmoved cut-off shunt are broken, at this time, the third power supply cannot supply power to the cut-off relay QDJ, the cut-off relay QDJ switches from the suck-up state to the drop-down state, and the switch power supply (the first power supply) corresponding to the drop of the cut-off relay QDJ in the

lines

71 and 73 in fig. 7 is broken in the

lines

71 and 73, and the control command transmitted from the interlock device 101 to the interface circuit 103 and the control command for the positioning operation performed by the positioning operation relay DCJ is cut.

That is, if the switch execution control command fails, the trip relay QDJ may be automatically tripped by the function of the switch trip circuit in fig. 5, so as to protect the switch efficiently and ensure the driving safety.

Referring to fig. 7, when the first forward path is in the open state, the interface circuit 103 transmits the positioning control command sent by the interlock device 101 to the switch control cabinet.

And a positioning operation relay DCJ in the turnout control cabinet is excited to control the turnout to execute positioning operation and obtain an operation result of a control command of the turnout to execute the positioning operation. Obviously, as can be seen from the switch disconnecting circuit in fig. 5, when the operation result is characterized that the positioning operation is successfully performed, the disconnecting relay QDJ keeps the pick-up state, i.e., the switch control cabinet controls the disconnecting relay QDJ to close in this case, and correspondingly, the first locking circuit in fig. 7 is powered by the first power supply, the locking protection relay SFJ 1/F2 in the first locking circuit is closed, the first locking circuit is operated, and then the switch locking circuit in fig. 6 is also operated to lock the switch; when the operation result represents that the positioning operation is failed to be executed, the disconnecting relay QDJ is switched to the falling state from the sucking-up state, correspondingly, the turnout disconnecting circuit in the figure 5 generates a disconnecting signal to control the disconnecting relay QDJ to be disconnected, correspondingly, the disconnecting relay QDJ in the figure 7 is disconnected, and due to the fact that the disconnecting relay QDJ is disconnected, all the centralized state relays JZZJ in the figure 7 lose excitation of the first power supply source and are switched to the falling state, the second power supply source and the second locking circuit are switched on, the second locking circuit works, and further the turnout locking circuit in the figure 6 also starts to work to lock the turnout. Wherein the first locking circuit comprises a first power supply and a locking protection relay SFJ F1/F2; the second locking circuit includes a second power supply source and a locking protection relay SFJ F1/F2. Therefore, no matter the turnout executes the control command successfully or fails, the turnout control system can lock the turnout, and unpredictable potential safety hazards are avoided.

Meanwhile, the centralized state relay JZZJ in fig. 7 is turned off, and is further configured to feed back a turn-off condition to the control mode switching circuit 104 through a relay interface of the centralized state relay JZZJ, and the control mode switching circuit 104 switches the operating mode of the turnout control system to the non-centralized state mode according to the feedback information.

After the switch operation, the switch control device 102 obtains the control result, referring to fig. 8, if the switch performs the positioning operation successfully, the N-bit switch A, B of the No. 1 lock pin and the N-bit switch A, B of the No. 11 lock pin in the line 83 and the line 84 are closed, the fourth power supply supplies power to the positioning indication relay DBJ, and the control result that the switch performs the positioning operation successfully is fed back to the interlocking device 101 through the relay interface after the positioning indication relay DBJ is excited; if the positioning operation of the turnout fails, a fault detection system in the turnout control cabinet excites the fault relays GZJ in the

lines

87 and 88, and a control result of the positioning operation failure of the turnout is fed back to the interlocking device 101 through a relay interface of the fault relay GZJ.

Similarly, when the control command is a control command of a flip operation, the operating principle of the turnout control system is similar to that when the control command is a positioning control command during operation, and the following description is not specifically provided, but only briefly described.

Referring to fig. 7, when the control command is a control command for a flip operation, the flip relay FJ in fig. 7 is energized to close, the

lines

72 and 73 including the flip relay FJ constitute a second forward path, and the control command 7 to turn off the relay QDJ is supplied with power from the circuit in fig. 5 to be in a suck-up state.

Through a second forward path consisting of the

lines

72 and 73 including the flip-flop relay FJ, the interface circuit 103 transmits the control command of the flip operation sent by the interlock device 101 to the switch control cabinet.

And a reverse operation relay FCJ in the turnout control cabinet is excited to control the turnout to execute reverse operation and obtain an operation result. When the operation result is that the switch is successfully inverted, the cut-off relay QDJ is controlled to keep a suction state, and at the moment, a first power supply is adopted to supply power to the first locking circuit to lock the switch; and when the operation result is that the switch is failed to perform the reverse operation, the control cut-off relay QDJ is switched to a falling state, and at the moment, a second power supply is adopted to supply power to the second locking circuit to lock the switch. The first locking circuit and the second locking circuit realize turnout locking by driving the turnout locking circuit in figure 6.

After the switch is operated, the switch control device 102 obtains a control result, referring to fig. 8, if the switch performs the flip operation successfully, the R-bit switch A, B of the latch pin 1 and the R-bit switch A, B of the latch pin 11 in the line 85 and the line 86 are closed, the fourth power supply supplies power to the flip indication relay FBJ, and the flip indication relay FBJ is excited and then feeds back the control result that the switch performs the positioning operation successfully to the interlocking device 101 through the relay interface; if the switch fails to perform the inversion operation, a fault detection system in the switch control cabinet excites fault relays GZJ in

lines

87 and 88, and a control result of the switch failure in the positioning operation is fed back to the interlocking equipment 101 through relay interfaces of the fault relays GZJ, so that the operation fault of the switch is found in time, and the driving safety is guaranteed.

Moreover, the centralized relay JZZJ in the interface circuit 103 is turned off, the condition is fed back to the control mode switching circuit 104 through the interface of the centralized relay JZZJ, and the control mode switching circuit 104 switches the operating mode of the turnout control system 400 to the non-centralized mode according to the feedback information.

Here, the switch control device 102 itself has a function of controlling the switch operation according to the control command, and in a centralized state, the switch control device can receive the control command of the interlock device 101, be controlled by the interlock device 101, and control the switch to execute the corresponding operation according to the information represented by the control command; in the non-centralized state, the switch control device 102 communicates with the switch control device 102 because all forward paths of the interface circuit 103 are closed, and the switch operation can also be controlled at the switch control device side. The concentrated state is a state in which the interlock device 101 controls the switch operation, and the non-concentrated state mode is a state in which the switch control device 102 controls the switch operation.

In the embodiment of the present application, a single turnout is taken as an example for illustration, and actually, a turnout control system for a double turnout, a triple turnout, and a multiple turnout is similar to a single turnout, so that a turnout control system for a double turnout, a triple turnout, and a multiple turnout implemented based on a similar principle should also belong to the protection scope of the present application.

Therefore, the switch control system provided by this embodiment realizes the connection between the interlocking device 101 and the switch control device 102 through the interface circuit 103, not only can transmit the control command of the interlocking device 101 to the switch control device 102, but also can feed back the control result obtained by the switch control device 102 to the interlocking device 101, and when the switch execution control command fails, a cut-off signal can be generated to cut off the control of the interlocking device 101 to the switch and the power supply of the switch in time, thereby providing conditions for the switch to be safe and stable, avoiding many potential safety hazards, and ensuring the safety of the switch control system when the switch is flexibly controlled.
