Description

Technical Field

[0001] This application relates to switch control technology, and particularly to a switch control system and an interface circuit. Background Art

[0002] As Figure 1 shown, in traditional switch control technology, generally, an interlocking device 101 controls switch operation. The interlocking device 101 sends a control command to a switch control device 102, and the switch control device 102 controls the switch to move from the original path to the target path according to the received control command. However, when the switch operation fails and it is necessary to cut off the control of the interlocking device 101 over the switch, the communication between the interlocking device 101 and the switch control device 102 cannot be automatically disconnected and needs to be manually disconnected to prevent the control command from continuing to be transmitted to the switch control device 102, and then local control is adopted to move the switch from the original path to the target path. The faults in the switch operation cannot be detected and eliminated in time; after the switch action is successful, it is also necessary to manually disconnect the communication between the interlocking device 101 and the switch control device 102.

[0073] To make the objectives, technical solutions, and advantages of the present application clearer and more understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts belong to the scope of protection of the present application. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0074] Figure 2 A schematic diagram of the structure of a turnout control system provided by an embodiment of the present application, as Figure 2 shown, the turnout control system 100 described in the embodiments 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 to the interlocking device 101; the other end of the interface circuit 103 is connected to the turnout control device 102; the interface circuit 103 includes at least two forward paths;

[0075] Composed of Figure 1 and Figure 2It can be seen that, different from the conventional switch control technologies, a switch control system 100 provided by an embodiment of the present application adds the interface circuit 103 between the interlocking device 101 and the switch control device 102. It can be seen that, in the switch control system 100 of the embodiment of the present application, the communication between the interlocking device 101 and the switch control device 102 is controlled through the interface circuit 103, and different types of control commands are separately transmitted through different forward paths in the interface circuit 103 without interference, so as to avoid affecting the normal operation of the entire switch control system in case of a circuit failure, which is beneficial to realizing safe and stable control of switch operations according to various situations occurring in the system.

[0076] Functionally,

[0077] the interlocking device 101 is configured to generate a control command and control the forward target path in the at least two forward paths to be in an open state according to the type of the control command;

[0078] the interface circuit 103 is configured to transmit the control command from the interlocking device to the switch control device by using the forward target path that is in an open state;

[0079] the switch control device 102 is configured to control the switch to perform a switch operation corresponding to the control command.

[0080] When the control command generated by the interlocking device 101 needs to be sent to the switch control device 102, the forward target path in the at least two forward paths needs to be opened according to the type of the control command. Thus, 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 open. In this way, the state of the forward path in the interface circuit 103 determines whether to open or cut off the communication between the interlocking device 101 and the switch control device 102, without the need for manual monitoring of the switch control system 100, ensuring that the switch control system 100 can safely and stably control switch operations, reducing the incidence of potential safety hazards, and increasing the safety of train operation.

[0081] Specifically, the type of the control command generated by the interlocking device 101 represents information on what operation the turnout is to perform, which is a type of control information and is a type of control command generated in an application scenario where the turnout needs to perform an action. The interlocking device 101 sends the generated control command to the interface circuit 103 to control the opening of the forward target path that can be opened corresponding to the type of the control command in the interface circuit 103, so as to transmit the control information to the turnout control device 102 and notify the turnout control device 102 to control the turnout to perform relevant operations according to the control information. Obviously, the transmission direction of the forward path is the direction from the interlocking device 101 to transmit the control information to the turnout 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. The interface circuit 103 is equivalent to an interface for controlling whether communication occurs between the interlocking device 101 and the turnout control device 102, and has the function of transmitting the control command on the forward target path opened according to the type of the control command.

[0082] By controlling the opening of the forward target path in the at least two forward paths according to the type of the control command to transmit the control command to the turnout control device 102, it is a way to control whether to open the path to transmit the signal (control command) through the device, which can accurately control the turnout operation and solves the technical problem that the turnout operation is not safe and stable due to manually controlling the opening or cutting off between the interlocking device 101 and the turnout control device 102. Moreover, the interlocking device 101 sends the control command and transmits the control command to the turnout control device 102 through the opening of the forward path in the interface circuit 103 instead of directly transmitting the control command to the turnout control device 102, enabling the turnout control system 100 to have a certain ability to detect its own faults and protect the safe operation of the system, and improving the accuracy and safety of controlling the turnout operation.

[0083] The turnout control system provided by the embodiment of the present application can be applied to any occasion where track communication realizes turnout control, such as the turnout control occasion of maglev turnouts, the turnout control occasion of subways, and the turnout control occasion of high-speed rails. That is, the interface circuit 103 provided by the embodiment of the present application is applicable to occasions for controlling various different types of turnouts. As a preferred method, it can be applied to the maglev turnout occasion and can effectively control the maglev turnout.

[0084] In the embodiment of the present application, the at least two forward paths include a first forward path and a second forward path;

[0085] Here, the first forward path and the second forward path are opened as the forward target path according to different types of control commands, and the control commands are transmitted to the switch control device 102; wherein, the first forward path and the second forward path are two different forward paths;

[0086] Specifically, in terms of implementation functions,

[0087] The interlocking device 101 is used to control the first forward path to be in an open state when the control command represents a command type for positioning the switch; and to control the second forward path to be in an open state when the control command represents a command type for reverse-positioning the switch;

[0088] Here, the interlocking device 101 has a control effect on which forward path in the interface circuit 103 is opened as the forward target path. Specifically, it is the control information represented in the control command that activates the opening of the forward target path;

[0089] The interface circuit 103 is used to transmit the control command of the command type representing the positioning operation of the switch to the switch control device 102 through the first forward path; or to transmit the control command of the command type representing the reverse-positioning operation of the switch to the switch control device 102 through the second forward path;

[0090] Here, the control command representing the positioning operation type is the positioning control command, and the control command representing the reverse-positioning operation type is the reverse-position control command. The opening of the forward target path is controlled according to the information represented by the control command. When the control command is the positioning control command, the first forward path is opened while the second forward path is closed; when the control command is the reverse-position control command, the second forward path is opened while the first forward path is closed. Therefore, a type of control command can only be transmitted on the forward target path that it can open. The function of the interface circuit 103 is to transmit the control command on the opened forward target path. It itself cannot control the opening and closing of the forward target path, but at least two forward paths it contains are activated by the control command to open the forward target path;

[0091] The switch control device 102 is used to control the switch to perform a positioning operation when the control command is the positioning control command; or to control the switch to perform a reverse-position operation when the control command is the reverse-position control command;

[0092] Here, the positioning control command activates the first forward path and is transmitted through the first forward path to the switch control device 102. The switch control device 102 controls the switch to perform a positioning operation according to this type of control command; or, the reverse position control command activates the second forward path and is transmitted through the second forward path to the switch control device 102. The switch control device 102 controls the switch to perform a reverse position operation according to this type of control command; by transmitting control commands of different opening types through different forward paths, the control commands of the interlocking device 101 can accurately reach the switch control device 102, reflecting the clear division of labor of the interface circuit 103 when transmitting control commands.

[0093] Here, the switch control device 102 controls the switch operation according to the type of control command, realizing the control of the switch operation by the interlocking device 101.

[0094] In the above solution, taking a single - turnout as an example, it 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 reverse position operation refers to switching the turnout from the second path to the first path; among them, the first path and the second path are relative concepts and can be converted to each other in actual applications. When the control command represents the command type of the positioning operation, the first forward path is activated, and the control command of the positioning operation is transmitted to the switch control device 102 to control the switch to switch from the first path to the second path; when the control command represents the command type of the reverse position operation, the second forward path is activated, and the control command of the reverse position operation is transmitted to the switch control device 102 to control the switch to switch from the second path to the first path. In the transmission of these two types of control commands, since the generated control command is of one command type and is guaranteed to be transmitted by an open forward target path, the problem that one forward path needs to transmit multiple control commands will not occur, which can reduce the complexity of the interface circuit 103 and make the switch control system 100 have a rigorous control logic.

[0095] In the above solution, it is the situation of the forward path for the interlocking device 101 to transmit control commands to the switch control device 102. In addition, the switch control system 100 provided by the embodiments of the present application can also implement a reverse path for the switch control device 102 to transmit control results to the interlocking device 101, which is specifically described as follows:

[0096] The interface circuit further includes at least two reverse paths;

[0097] Here, the at least two reverse paths are used for the switch control device 102 to transmit information to the interlocking device 101;

[0098] The switch control device 102 is configured to obtain a control result for controlling the switch operation; according to the type of the control result, control the reverse target path in the at least two reverse paths to be in an open state;

[0099] The interface circuit 103 is configured to transmit the control result from the switch control device to the interlocking device 101 by using the reverse target path that is in an open state;

[0100] The interlocking device 101 is configured to receive and output the control result.

[0101] It can be seen that a switch control system 100 provided by an embodiment of the present application adds an interface circuit 103 between the interlocking device 101 and the switch control device 102, and can also be used when the control result obtained by the switch control device 102 according to the switch operation situation needs to be sent to the interlocking device 101, to open the corresponding reverse target path in the at least two reverse paths according to the type of the control result. In this way, the interlocking device 101 can timely know the switch operation situation, ensuring that the switch control system 100 can safely and stably control the switch operation, reducing the occurrence rate of potential safety hazards, and increasing the safety degree of train operation.

[0102] Specifically, the type of the control result obtained by the switch control device 102 represents information on the situation of the switch executing a control command, which is a type of control information, and for different operation situations of the switch executing a control command in the application scenario, a type of control result is generated; the switch control device 102 sends the obtained control result, controls the reverse target path in the at least two reverse paths in the interface circuit 103 to be opened, and gives the control result to the interlocking device 101. Those skilled in the art know that the forward path and the reverse path are relative concepts and are not specifically described herein. The interface circuit 103 is equivalent to the interface between the interlocking device 101 and the switch control device 102, and has the function of transmitting the control result on the corresponding reverse path opened according to the control result.

[0103] In the embodiment of the present application, the at least two reverse paths include a first reverse path and a second reverse path;

[0104] Here, the reverse target path is controlled to be opened according to the information represented by the control result. When the control result represents that the positioning operation is successful, the first reverse path is opened, while the second reverse path is closed; when the control result represents that the reverse positioning operation is successful, the second reverse path is opened, while the first reverse path is closed. Therefore, a control result can only be transmitted on the target reverse path that it can open;

[0105] In terms of function implementation,

[0106] The switch control device 102 is further configured to control the first reverse path to an open state when the control result represents a successful result of the switch positioning operation; or, to control the second reverse path to an open state when the control result represents a successful result of the switch reverse position operation;

[0107] The interface circuit 103 is configured to use the first reverse path in the open state to transmit the successful result representing the switch positioning operation from the switch control device 102 to the interlocking device 101; or, to use the second reverse path in the open state to transmit the successful result representing the switch reverse position operation from the switch control device to the interlocking device 101;

[0108] Here, the function of the interface circuit 103 is to transmit the current control result on the open reverse target path. It itself cannot control the opening or closing of the reverse target path. Instead, at least two forward paths it contains are excited by the control result to open the reverse target path;

[0109] Correspondingly,

[0110] The interlocking device 101 is configured to receive and output the successful result representing the switch positioning operation or the successful result representing the switch reverse position operation;

[0111] The interlocking device 101 receives and outputs the successful result representing the switch positioning operation through the first reverse path; or, receives and outputs the successful result representing the switch reverse position operation through the second reverse path.

[0112] Due to the reverse path in the interface circuit 103, the interlocking device 101 can not only generate and send control commands, but also receive the control results of the switch operation control and obtain the feedback of the sent control commands, making the control logic in the whole switch control operation more perfect and further ensuring that the switch operation can be completed in a safe and rigorous working environment.

[0113] Further, the at least two reverse paths include a third reverse path; the control result further includes a control result representing the failure of the switch positioning operation or reverse position operation;

[0114] In terms of function realization,

[0115] When the third reverse path is in an open state, the interface circuit 103 uses the third reverse path to transmit the control result representing the failure of the positioning operation or reverse position operation to the interlocking device 101;

[0116] The switch control device 102 is further configured to control the third reverse path to an open state when the control result represents a failed positioning operation or a failed reverse operation result;

[0117] The interface circuit 103 is configured to transmit the control result representing a failed positioning operation or a failed reverse operation result from the switch control device 102 to the interlocking device 101 by using the third reverse path that is in an open state;

[0118] Correspondingly,

[0119] The interlocking device 101 is configured to receive and output the control result representing a failed positioning operation or a failed reverse operation result.

[0120] In the above solution, when the switch fails to execute the control command operation, the switch control device 102 feeds back this type of control result to the interlocking device 101 through the interface circuit 103, enabling the interlocking device 101 to promptly know that the switch operation has gone wrong. It realizes the monitoring of the switch operation situation with a rigorous and comprehensive operation logic, thereby ensuring the train operation safety.

[0121] In an embodiment of the present application, the interface circuit further includes at least two locking circuits;

[0122] The switch control device is configured to obtain the control result for controlling the switch operation; according to the type of the control result, control the target locking circuit among the two locking circuits to an open state;

[0123] The interface circuit 103 is configured to lock the switch by using the target locking circuit that is in an open state.

[0124] By locking the switch by the switch control device 102 and the interface circuit 103 respectively under different control result types, it not only ensures that the switch can be promptly locked when the switch fails to execute the control command, preventing unpredictable failures and taking corresponding measures for the switch after the operation failure in a timely manner, but also ensures that the switch is promptly locked when the switch successfully executes the control command, preventing potential safety hazards such as the switch moving when a train passes by later.

[0125] Wherein, the at least two locking circuits include a first locking circuit and a second locking circuit;

[0126] Here, the at least two locking circuits can lock the switch under different types of control results;

[0127] In terms of function implementation,

[0128] The switch control device 102 is configured to control the first locking circuit to be in an open state when the control result indicates a successful switch operation result; correspondingly, the interface circuit is configured to lock the switch by using the first locking circuit that is in an open state;

[0129] Alternatively, the switch control device 102 is configured to control the second locking circuit to be in an open state when the control result indicates a failed switch operation result; correspondingly, the interface circuit is configured to lock the switch by using the second locking circuit that is in an open state.

[0130] Here, the switch control device 102 obtains a control result, and according to the type of the control result, activates the target locking circuit to lock the switch. The interface circuit 103 locks the switch by using the activated target locking circuit, making the switch immovable;

[0131] Specifically, in order to activate the target locking circuit, the switch control device 102 is configured to use a first power supply when the control result indicates a successful switch operation result. The first power supply is used to supply power to the first locking circuit, and the first locking circuit being supplied with power is in an open state;

[0132] The switch control device 102 is configured to use a second power supply when the control result indicates a failed switch operation result. The second power supply is used to supply power to the second locking circuit, and the second locking circuit being supplied with power is in an open state.

[0133] In an embodiment of the present application, the switch control device 102 is further configured to generate a cut-off signal when a fault occurs in the switch operation; the cut-off signal causes the forward path that is in an open state among the at least two paths to be cut off.

[0134] In the above solution, the switch control device 102 generates a cut-off signal to disconnect the forward path that is in an open state in the interface circuit 103 according to the control result of the switch's failure to execute the control command operation, timely cutting off the control of the switch by the interlocking device 101, and instead directly controlling the switch by the switch control device 102, avoiding the disadvantages in the prior art that the control result is not timely enough and the manual cut-off takes longer.

[0135] In the embodiment of the present application, the interlocking device 101 is connected to the switch control device 102 through the interface circuit 103. The interlocking device 101 transmits different types of control commands to the switch control device 102 through at least two forward paths, and only one forward path can be opened each time to transmit one type of control command. The switch control device 102 can not only receive the control command and control the switch to perform corresponding operations, but also obtain the control result of controlling the switch to execute the control command, and open the reverse target path according to the type of the control result, and feedback the control result to the interlocking device 101 through the reverse target path, and supply power to the corresponding locking circuit according to the type of the control result to turn on the target locking circuit for the interface circuit 103 to use for switch locking.

[0136] In addition, the switch control device 102 can also generate a cut-off signal according to the control result indicating that the switch operation fails, disconnect the forward path in the interface circuit 103 that is in the open state, timely cut off the control of the switch by the interlocking device 101, and instead directly control the switch by the switch control device 102, avoiding the disadvantages of insufficiently timely obtaining the control result and longer manual cut-off time in the prior art, realizing safe and stable logical control of the switch, and reducing the potential safety hazards when the switch executes the control command.

[0137] As Figure 3 shown, it is a schematic diagram of the information representation structure of a switch control system provided by an embodiment of the present application. The switch control system 100 includes: an interlocking device 101, a switch control device 102, and an interface circuit 103; wherein, one end of the interface circuit 103 is connected to the interlocking device 101; the other end of the interface circuit 103 is connected to the switch control device 102; the interface circuit 103 includes at least two forward paths;

[0138] The interlocking device 101 is configured to generate a control command and control the forward target path in the at least two forward paths to be in an open state according to the type of the control command;

[0139] The interface circuit 103 is configured to transmit the control command from the interlocking device 101 to the switch control device 102 by using the open forward target path;

[0140] The switch control device 102 is configured to control the switch to perform switch actions according to the control information represented by the control command.

[0141] Figure 3Among them, the control information transmitted by the interlocking device 101 to the interface circuit 103 is a control command. The interface circuit 103 converts the control command into a relay signal through a relay interface and transmits it to the switch control device 102. The switch control device 102 controls the switch to act according to the control information represented by the relay signal, obtains the control result, and feeds back the control result to the interlocking device 101 through the interface circuit 103.

[0142] As Figure 4 shown, another switch control system 400 provided by an embodiment of the present application includes an interlocking device 101, an interface circuit 103, a switch control device 102, and a control mode conversion circuit 104. Among them, one end of the interface circuit 103 is connected to the interlocking device 101; the other end of the interface circuit 103 is connected to the switch control device 102; the interface circuit 103 includes at least two forward paths; the control mode conversion circuit is respectively connected to the interlocking device 101, the interface circuit 103, and the switch control device 102;

[0143] The interlocking device 101 is configured to generate a control command and control the forward target path among the at least two forward paths to be in an open state according to the type of the control command;

[0144] The interface circuit 103 is configured to transmit the control command from the interlocking device 101 to the switch control device by using the forward target path in an open state;

[0145] The switch control device 102 is configured to control the switch to perform a switch operation corresponding to the control command.

[0146] The control mode conversion circuit 104 is configured to control the switch control system to operate in a centralized state mode or a non-centralized state mode.

[0147] Specifically, the working principle of the switch control system 400 is basically the same as that of the switch control system 100 described above, and will not be elaborated here.

[0148] However, it should be noted that the control mode conversion circuit 104 can set the working state mode of the switch control system 400 to the centralized state mode or the non - centralized state mode. In the centralized state mode, the interlocking device 101 sends the generated control commands to the switch control device 102 via the interface circuit 103, and controls the switch to act according to the type of the control commands; while in the non - centralized state mode, the switch control device 102 directly controls the switch to act. Therefore, the significance of the interface circuit 103 is not only to serve as the interface between the interlocking device 101 and the switch control device 102, but also to utilize the opening and closing of the forward target path in at least two forward paths it contains to enable the switch control system 400 to work in the centralized state mode or the non - centralized state mode, reflecting the logical integrity of the operation of the switch control system 400.

[0149] The following combines Figures 5 - 9 to specifically illustrate the working principle of a switch control system applied to a maglev switch provided in an embodiment of the present application. Among them, Figures 5 - 8 are the circuit structures involved in the embodiments of the present application; Figure 9 is an application scenario of an embodiment of the present application.

[0150] As shown in Table 1, it is Figures 5 - 8 the detailed information of the relays used in the circuit structure in; among them, there are the name, name abbreviation and normal state of the relay. The name of the relay represents the function of the relay, the abbreviation is the Chinese pinyin abbreviation of the name, the normal state is the state when not excited, and the excitation means providing a normal working magnetic field for the relay.

[0151] It should be stated here that in the embodiments of the present application, the relays with the same name (such as the cut - off relay QDJ, the centralized state relay JZZJ, etc.) appearing in different circuits or the same circuit are all the same relay device, but they are different structural parts of the same relay device; this is because the structure of the relay mainly includes a coil, and the coil has at least four contacts, so the relay has at least four logic switches and can realize at least four different logical functions.

[0179] Functionally,

[0180] Figure 5 It is a turnout cut-off circuit located in the turnout control device 102, which is used to control Figure 7 all the cut-off relays in it to cut off when the turnout fails to execute the turnout control command within the first preset time or fails to complete the turnout control command within the second preset time, and cut off the turnout control command from the interlocking device 101 and the turnout power supply from the interface circuit 103 for the turnout control cabinet. The first preset time is the preset waiting time for the turnout to start operating, and the second preset time is the preset waiting time for the turnout to complete the operation;

[0181] Figure 6 It is a turnout locking circuit located in the turnout control system, which is used to lock the turnout when the turnout completes the control command or fails to complete the control command, and Figure 7 together with the first locking circuit and the second locking circuit in the circuit structure to complete the locking of the turnout. On the one hand, it ensures that the turnout is locked on the new path after the turnout operation is successful. On the other hand, it locks the turnout in time when the turnout fails to avoid bad results;

[0182] Figure 7 It is a schematic diagram of the circuit structure of the forward path of the interface circuit 103 provided by the embodiment of the present application, which is used to transmit the control command of the interlocking device 101 (taking the single-opening turnout as an example, including the control command for the normal position operation or the reverse position operation) to the turnout control cabinet (the control device located in the turnout control device 102) in the centralized control mode, and is also used to feedback the information on whether the turnout control system 100 can continue to work in the centralized state mode to Figure 9 the control mode conversion circuit 104 in it, ensuring the logical integrity of the turnout control system 100;

[0183] Figure 8 It is a schematic diagram of the circuit structure of the reverse path of the interface circuit 103 provided by the embodiment of the present application, which is used for the turnout control system to obtain the control result of the turnout executing the control command and feedback it to the interlocking device 101, and is also used to feedback the fault result to the interlocking device 101; among them, the fault result is obtained by the fault detection system in the turnout control device 102, and a relay signal is generated to the interlocking device 101 through the excitation Figure 8 of the fault relay GZJ in it, timely feeding back the action situation of the turnout

[0184] The above Figures 5 - 8 circuit structure in Figure 9 The specific working principle in the application scenario is referred to the subsequent relevant description and will not be described in detail here.

[0185] Next, taking the single-opening turnout as an example, combined with Figure 9 the application scenario of Figures 5 - 8The mutual cooperation of the circuit structures will be used to elaborate in detail on the working principle of the switch control system 400:

[0186] First, the interlocking device 101 generates control commands and sends the control commands to the control mode conversion circuit 104 and the interface circuit 103 respectively.

[0187] The control mode conversion circuit 104 controls the switch control system to operate in the centralized state mode according to the control command of the interlocking device 101, that is, the working mode in which the interlocking device 101 controls the switch operation, and sends corresponding commands to the interface circuit 103 to control Figure 7 All the centralized state relays JZZJ in it to pick up (close), and select a reasonable working mode according to the working conditions of the switch to control the switch control system.

[0188] When the control command is the positioning control command, Figure 7 In it, the positioning relays DJ in lines 71 and 73 receive the positioning control command of the interlocking device 101 through the relay interface, get excited and close, and the cut-off relay QDJ is cut off by Figure 5 The circuit in it supplies power and is in the picked-up state; at this time, lines 71 and 73 form the first forward path.

[0189] Specifically, the working state of the cut-off relay QDJ is determined by Figure 5 The switch cut-off circuit in it, and the specific working principle is as follows:

[0190] When the interlocking device 101 sends a control command to the interface circuit 103, in Figure 5 In it, the third power supply powers the switch cut-off circuit, the positioning indication relay DBJ, the reverse position indication relay FBJ, the timeout cut-off relay CSQDJ, and the non-moving cut-off relay WDQDJ pick up, the timeout cut-off shunt and the non-moving cut-off shunt form a path, and supply power and excitation to the cut-off positioner QDJ, and the cut-off positioner QDJ picks up.

[0191] Furthermore, a first preset time is set for the non-moving cut-off relay WDQDJ, and the non-moving cut-off relay WDQDJ will automatically drop after exceeding the first preset time; a second preset time is set for the timeout cut-off relay CSQDJ, and the timeout cut-off relay CSQDJ will automatically drop after exceeding the second preset time.

[0192] Generally, the action indication time of the switch is about 4.5 seconds (that is, the positioning operation starts within 4.5 seconds), and it takes about 15 seconds to complete the positioning operation. In this embodiment, the first preset time for the non-moving cut-off relay WDQDJ to remain picked up after excitation can be set to 7 seconds, and the second preset time for the timeout cut-off relay CSQDJ to remain picked up after excitation can be set to 30 seconds.

[0193] If the turnout control cabinet fails to control the turnout to perform the positioning operation, that is, if the time when the turnout does not start to perform the positioning operation exceeds 7 seconds, the non-moving cut-off relay WDQDJ changes from the picked-up state to the dropped state; and if the turnout fails to complete the positioning operation within 30 seconds, the overtime cut-off relay CSQDJ also changes from the picked-up state to the dropped state, the overtime cut-off shunt and the non-moving cut-off shunt are open-circuited, and at this time, the third power supply cannot supply power to the cut-off relay QDJ, and the cut-off relay QDJ changes from the picked-up state to the dropped state, corresponding to Figure 7 In the middle line 71 and 73, the cut-off relay QDJ drops, the line 71 and 73 are open-circuited, and the control command transmitted by the interlocking device 101 to the interface circuit 103 and the turnout power supply (the first power supply) for the control command of the positioning operation relay DCJ to perform the positioning operation are cut off.

[0194] That is to say, if the turnout fails to execute the control command, the cut-off relay QDJ can be automatically disconnected through the Figure 5 function of the turnout cut-off circuit in, which can efficiently protect the turnout and ensure the safety of train operation.

[0195] Reference Figure 7 , when the first forward path is in the open state, the interface circuit 103 transmits the positioning control command sent by the interlocking device 101 to the turnout control cabinet.

[0196] The positioning operation relay DCJ in the turnout control cabinet is excited, controls the turnout to perform the positioning operation, and obtains the operation result of the control command for the turnout to perform the positioning operation. Obviously, from Figure 5 the turnout cut-off circuit in, when the operation result indicates that the positioning operation is successfully executed, the cut-off relay QDJ remains in the picked-up state, that is, in this case, the turnout control cabinet controls the cut-off relay QDJ to close. Correspondingly, Figure 7 in, the first locking circuit is powered by the first power supply, the locking protection relay SFJ F1 / F2 in the first locking circuit closes, the first locking circuit works, and then Figure 6 in, the turnout locking circuit also starts to work to lock the turnout; when the operation result indicates that the positioning operation fails, the cut-off relay QDJ switches from the picked-up state to the dropped state. Correspondingly, Figure 5 in, the turnout cut-off circuit generates a cut-off signal to control the cut-off relay QDJ to disconnect. Correspondingly, Figure 7 in, the cut-off relay QDJ disconnects, and because the cut-off relay QDJ disconnects, Figure 7 in, all the centralized state relays JZZJ lose the excitation of the first power supply and change to the dropped state, connecting the second power supply and the second locking circuit, and the second locking circuit works, and then Figure 6The switch locking circuit therein also starts to work to lock the switch. Among them, the first locking circuit includes a first power supply and a locking protection relay SFJ F1 / F2; the second locking circuit includes a second power supply and a locking protection relay SFJ F1 / F2. Therefore, whether the switch executes the control command successfully or fails, the switch control system can lock the switch to avoid unpredictable safety hazards.

[0197] Meanwhile, Figure 7 the centralized status relay JZZJ therein disconnects, and is also used to feedback the disconnection situation to the control mode conversion circuit 104 through the relay interface of the centralized status relay JZZJ. The control mode conversion circuit 104 switches the working mode of the switch control system to the non-centralized status mode according to the feedback information.

[0198] After the switch is operated, the switch control device 102 obtains the control result. Referring to Figure 8 , if the switch executes the positioning operation successfully, the 1st locking pin N-position switches A and B and the 11th locking pin N-position switches A and B in line 83 and line 84 close. The fourth power supply supplies power to the positioning indication relay DBJ. After the positioning indication relay DBJ is excited, it feeds back the control result of the switch executing the positioning operation successfully to the interlocking device 101 through the relay interface; if the switch executes the positioning operation fails, the fault detection system in the switch control cabinet energizes the fault relay GZJ in line 87 and 88, and feeds back the control result of the switch executing the positioning operation fails to the interlocking device 101 through the relay interface of the fault relay GZJ.

[0199] Similarly, when the control command is a reverse position operation control command, the working principle of the switch control system is similar to that when the operation command is a positioning control command, and no specific description will be made below, only a brief description will be given.

[0200] Referring to Figure 7 , when the control command is a reverse position operation control command, make Figure 7 the reverse position relay FJ therein be excited and closed. The lines including the reverse position relay FJ in line 72 and line 73 form a second forward path, and the control command 7 cuts off the relay QDJ and is powered by the circuit in Figure 5 and is in the picked-up state.

[0201] Through the second forward path formed by the lines including the reverse position relay FJ in line 72 and line 73, the interface circuit 103 transmits the control command of the reverse position operation sent by the interlocking device 101 to the switch control cabinet.

[0202] The reverse operation relay FCJ in the switch control cabinet is energized, controlling the switch to perform a reverse operation and obtaining the operation result. When the operation result is that the switch successfully performs the reverse operation, the control cut-off relay QDJ remains in the pulled-in state. At this time, the first power supply is used to supply power to the first locking circuit to lock the switch; when the operation result is that the switch fails to perform the reverse operation, the control cut-off relay QDJ switches to the dropped state. At this time, the second power supply is used to supply power to the second locking circuit to lock the switch. The first locking circuit and the second locking circuit drive Figure 6 the switch locking circuit in it to achieve switch locking.

[0203] After the switch is operated, the switch control device 102 obtains the control result. Referring to Figure 8 , if the switch successfully performs the reverse operation, the 1st locking pin R position switches A and B and the 11th locking pin R position switches A and B in line 85 and line 86 are closed. The fourth power supply supplies power to the reverse indication relay FBJ. After the reverse indication relay FBJ is energized, it feeds back the control result of the switch successfully performing the normal position operation to the interlocking device 101 through the relay interface; if the switch fails to perform the reverse operation, the fault detection system in the switch control cabinet energizes the fault relay GZJ in line 87 and 88, and feeds back the control result of the switch failing to perform the normal position operation to the interlocking device 101 through the relay interface of the fault relay GZJ, timely detecting the operation fault of the switch and ensuring the train operation safety.

[0204] Moreover, the centralized status relay JZZJ in the interface circuit 103 is opened, and the situation is fed back to the control mode conversion circuit 104 through the interface of the centralized status relay JZZJ. The control mode conversion circuit 104 switches the working mode of the switch control system 400 to the non-centralized status mode according to the feedback information.

[0205] Here, the switch control device 102 itself has the function of controlling the switch operation according to the control command. In the centralized status, it can receive the control command of the interlocking device 101, be controlled by the interlocking device 101, and control the switch to perform the corresponding operation according to the information represented by the control command; in the non-centralized status, the communication between the switch control device 102 and the switch control device 102 is because all the forward paths of the interface circuit 103 are in the closed state, and the switch operation can also be controlled at the switch control device end. Among them, the centralized status is the state where the interlocking device 101 controls the switch operation, and the non-centralized status mode is the state where the switch control device 102 controls the switch operation.

[0206] In the embodiments of the present application, a single turnout is taken as an example for illustration. In fact, the turnout control systems of double turnouts, triple turnouts, and multi-turnouts are similar to that of single turnouts. Therefore, the turnout control systems of double turnouts, triple turnouts, and multi-turnouts implemented based on the similar principle should also fall within the protection scope of the present application.

[0207] Therefore, the turnout control system provided in this embodiment realizes the connection between the interlocking device 101 and the turnout control device 102 through the interface circuit 103. It can not only transmit the control command of the interlocking device 101 to the turnout control device 102, but also feedback the control result obtained by the turnout control device 102 to the interlocking device 101. And when the turnout fails to execute the control command, it can also generate a cut-off signal to timely cut off the control of the interlocking device 101 on the turnout and the power supply of the turnout, providing conditions for the safe and stable switching path of the turnout, avoiding many potential safety hazards, and ensuring the safety while flexibly controlling the turnout.

[0208] As Figure 10 shown, the embodiments of the present application also provide an interface circuit 103, including a receiving circuit 1 and at least two forward paths connected to the receiving circuit 1; wherein,

[0209] The receiving circuit 1 is used to receive a control command; wherein, the control command is used to control the turnout.

[0210] The forward target path among the at least two forward paths that is controlled to be in the open state is used to output the control command; wherein, the forward target path controlled to be in the open state is determined according to the type of the control command.

[0211] Wherein, the at least two forward paths include forward path 21, forward path 22,..., forward path 2m, and m is a positive integer greater than 2.

[0212] Specifically, according to the type of the control command received by the receiving circuit 1, the forward target path among the at least two forward paths is opened, and the interface circuit 103 realizes the transmission of the control command generated by the interlocking device 101 to the turnout control device 102; by controlling the on-off of the forward paths in the interface circuit 103 through the control command, appropriate measures can be taken when the turnout needs to execute the control command and when it does not need the control command, so as to safely and stably control the turnout operation.

[0213] As Figure 11 shown, the embodiments of the present application also provide another interface circuit 103, including a receiving circuit 2 and at least two reverse paths connected to the receiving circuit 2; wherein,

[0214] The receiving circuit 2 is configured to receive a control result generated for a control command, where the control command is used to control a turnout.

[0215] The reverse target path that is controlled to be in an open state among the at least two reverse paths is configured to output the control result, where the reverse target path that is controlled to be in an open state is determined according to the type of the control result.

[0216] Wherein, the at least two reverse paths include a reverse path 31, a reverse path 32, …, a reverse path 3n, and n is a positive integer greater than 2.

[0217] It can be understood that m and n may be equal or may not be equal, depending on the specific situation.

[0218] Specifically, according to the type of the control result obtained by the receiving circuit 2, the reverse target path among the at least two reverse paths is opened, and the interface circuit 103 transmits the control result obtained by the turnout control device 102 to the interlocking device 101 through the reverse target path. By controlling the on / off of the reverse path in the interface circuit 103 according to the control result, the situation of the turnout executing the control command can be fed back to the interlocking device 101, so as to obtain the turnout operation situation in a timely manner and take reasonable measures next.

[0219] The embodiment of the present application further provides another interface circuit 103, and its circuit structure can refer to the combination of Figure 10 and Figure 11 and includes a first receiving circuit and at least two forward paths connected to the first receiving circuit; it further includes a second receiving circuit and at least two reverse paths connected to the second receiving circuit; wherein,

[0220] The first receiving circuit is configured to receive a control command, where the control command is used to control a turnout.

[0221] The forward target path that is controlled to be in an open state among the at least two forward paths is configured to output the control command, where the forward target path that is controlled to be in an open state is determined according to the type of the control command.

[0222] The second receiving circuit is configured to receive a control result generated for a control command.

[0223] The reverse target path that is controlled to be in an open state among the at least two reverse paths is configured to output the control result, where the reverse target path that is controlled to be in an open state is determined according to the type of the control result.

[0224] On the one hand, according to the type of the control command received by the first receiving circuit, the forward target path in the at least two forward paths is opened, and the interface circuit 103 realizes the transmission of the control command generated by the interlocking device 101 to the switch control device 102; by controlling the on / off of the forward path in the interface circuit 103 through the control command, appropriate measures can be taken when the switch needs to execute the control command and when it does not need the control command, so as to control the switch operation safely and stably.

[0225] On the other hand, according to the type of the control result received by the second receiving circuit, the reverse target path in the at least two reverse paths is opened, and the interface circuit 103 realizes the transmission of the control result obtained by the switch control device to the interlocking device 101 through the reverse target path; by controlling the on / off of the reverse path in the interface circuit 103 through the control result, the situation of the switch executing the control command can be fed back to the interlocking device 101, so as to obtain the switch operation situation in time and take reasonable measures next.

[0226] In the above solution, the interface circuit 103 provides a complete logical condition for the switch control system 100 to control the switch; the interface circuit 103 is equivalent to the interface between the interlocking device 101 and the switch control circuit. The interlocking device 101 sends the control command to the switch control device 102 through the interface circuit 103, and the switch control device 102 feeds back the control result to the interlocking device 101 through the interface circuit 103. Among them, when the interlocking device 101 sends a control command to the switch control device 102, it is received by the first receiving circuit, and the control command is transmitted through the corresponding forward target path; when the switch control device 102 feeds back the control result to the interlocking device 101, it is received by the second receiving circuit, and the control result is transmitted through the corresponding reverse target path.

[0227] The present application discloses a switch control system and an interface circuit. By controlling the on / off of the forward target path in at least two forward paths in the interface circuit, the control of the interlocking device sending a control command to the switch control device is realized. By controlling the on / off of the reverse target path in at least two reverse paths in the interface circuit, the timely feedback of the switch operation situation is realized. In the case of switch operation failure, the forward path in the open state can also be disconnected, solving the technical problem in the related art that the switch control system cannot respond to the switch operation failure in time and stop implementing the control command sent by the interlocking device, and cannot ensure the safe and stable control of the switch movement. At the same time, a complete logic for controlling the switch is also realized.
