Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to an automatic turning method, system and operation mechanism of a turnout. Background Art

[0002] At present, with the development of my country's rail transit industry, it will face various complex operation scenarios. For specific operation scenarios, the signal system is required to provide relevant measures to reduce manual intervention to improve the automation efficiency of the system. In some scenarios, the turnout should be set to be in a specified position normally. For example, when a safety line is set for a national railway station, the turnout needs to be continuously opened to the position leading to the safety line under normal circumstances to ensure the operational safety when the train cannot stop for some reason.

[0003] In the signal system of rail transit, the control of turnouts is generally achieved by an interlocking system. At present, for turnouts that are continuously opened in a specific direction, when the direction of the turnout is in the opposite position and is not locked, a turnout alarm message is generally set to remind the on-duty personnel to pay attention to the turnout operation. Although this method can give prompts to the on-duty personnel in a timely manner, under the condition of high operating pressure, the on-duty personnel may not be able to respond to the alarm in time to operate the turnout. Therefore, in view of the defects of this current scenario, a safe and reliable method is provided, which can check whether the turnout is in an unlocked state and automatically reverse the turnout action when the action conditions are met. Summary of the invention

[0004] The purpose of the present invention is to provide a method, system and operation mechanism for automatic rotation of turnouts, which improve the automation level in the field of rail transportation, reduce the workload of operators, and ensure the safety and reliability of the automatic rotation system.

[0005] In order to achieve the above object, in a first aspect, the present invention provides an automatic turning method of a turnout, comprising:

[0006] The interlocking system sets the attribute of the turnout that deviates from the normal position as the automatic rotation attribute, and determines whether the turnout with the automatic rotation attribute meets the conditions for the turnout action;

[0007] After the turnout with automatic rotation attribute meets the turnout action conditions, the interlocking system starts the delay countdown of the turnout automatic rotation, and continuously determines whether the turnout with automatic rotation attribute meets the turnout action conditions during the delay countdown of the turnout automatic rotation;

[0008] When the delay countdown for the automatic turnout rotation ends and the turnout still meets the turnout action conditions, the interlocking system controls the turnout to complete the rotation action.

[0009] Optionally, the positioning position of the turnout is set to the normal position, and the interlocking system sets the attribute of the turnout in the reverse position to the automatic rotation attribute; or, the reverse position of the turnout is set to the normal position, and the interlocking system sets the attribute of the turnout in the positioning position to the automatic rotation attribute. Optionally, the situation in which the turnout rotates to the reverse position includes at least:

[0010] The train route requires that the turnout be in the reverse position;

[0011] Due to the need for track debugging, the turnout needs to be operated to the reverse position alone;

[0012] Because the train passes through the positioning position of a set of single-action turnouts of the Y-type turnout, it is necessary to operate the protection of another set of double-action turnouts of the Y-type turnout and lock them to the reverse position.

[0013] Optionally, the conditions for the switch action include: the switch is not in a blocked state and the switch is not in a single locked state, and the switch is not in a locked state, and the switch has not received an operation command to the positioning position or is in a positioning operation process.

[0014] Optionally, the situations in which the turnout is not in a locked state include: the turnout is not in an approach locking state in a reverse position, the track section where the turnout is located is not occupied, the turnout is not protectively locked, the turnout is not deadlocked or non-approach locked, and in an urban rail project, the turnout is not continuously protectively locked.

[0015] Optionally, the method for the interlocking system to determine whether the turnout meets the turnout action conditions includes:

[0016] If any of the switch action conditions are not met, the interlocking system will continue to determine whether the switch action conditions are met in each operation cycle until the switch meets the switch action conditions;

[0017] The operation cycle of the interlocking system is the time it takes for the interlocking system to complete a condition check of a turnout action.

[0018] Optionally, the method by which the interlocking system continuously determines whether the turnout with the automatic rotation attribute meets the turnout action condition within the delay countdown of the turnout automatic rotation comprises:

[0019] When the turnout meets the turnout action condition in an operation cycle of the interlocking system during the delay countdown of the turnout automatic rotation, the interlocking system will send the prompt information of the turnout action condition check in the operation cycle of the interlocking system to the monitoring system and the dispatching system;

[0020] When the turnout does not meet the turnout action conditions in an interlocking cycle during the delay countdown of the turnout automatic rotation, the interlocking system will immediately stop the delay countdown of the turnout automatic rotation and end the turnout automatic rotation process;

[0021] The prompt information is used to reflect whether the turnout meets the turnout action conditions in the operation cycle of the interlocking system.

[0022] Optionally, the method for the interlocking system to control the turnout to complete the rotation action includes:

[0023] After the delay countdown for the automatic rotation of the turnout ends and the interlocking system checks that the turnout still meets the conditions for turnout action, the interlocking system will send a turnout movement command to the positioning position to the turnout machine that controls the turnout rotation, and keep the turnout movement command valid continuously.

[0024] Optionally, it also includes: obtaining the turnout through the interlocking system to complete the rotation action;

[0025] Among them, the method of obtaining the situation of the turnout completing the rotation action through the interlocking system includes:

[0026] Setting a maximum action time in the interlocking system, the maximum action time being the maximum time for which the turnout can be continuously operated;

[0027] When the interlocking system sends a switch command, the countdown of the maximum action time will start, and the maximum action time will start from the time when the switch-away machine executes the switch command;

[0028] When the maximum action time is within and the switch-removing machine executes the switch-moving command normally, the interlocking system will send the switch indication information to the monitoring system and the dispatching system, and make the monitoring system and the dispatching system synchronously display the countdown of the maximum action time;

[0029] If within the maximum action time, the interlocking system collects the turnout indication information as positioning indication information, the turnout completes automatic rotation; at this time, the interlocking system sends the turnout's positioning indication information to the monitoring system and the dispatching system, and stops the countdown of the maximum action time synchronously displayed by the monitoring system and the dispatching system.

[0030] Optionally, the method for obtaining the situation that the turnout completes the rotation action through the interlocking system also includes:

[0031] When the maximum action time is exceeded and the interlocking system fails to collect the position information of the turnout, the interlocking system will immediately stop the countdown of the maximum action time;

[0032] If the switch command is executed again during the maximum action time, the interlocking system will restart the countdown of the maximum action time.

[0033] If the switch-out machine still cannot execute the switch-out command after the countdown of the maximum action time ends, the interlocking system will stop maintaining the validity of the switch-out command, and stop the monitoring system and the dispatching system from synchronously displaying the countdown of the maximum action time; at the same time, after the interlocking system collects that the switch is in the lost meter state, the interlocking system will start the countdown of the alarm delay, and send an alarm message to the monitoring system and the dispatching system after the countdown of the alarm delay ends, to remind the operator to handle it;

[0034] The alarm information is used to reflect that the switch is in a lost meter state.

[0035] In a second aspect, the present invention further provides a computing mechanism comprising a processor and a computer-readable storage medium, wherein the computer-readable storage medium stores computer-executable instructions that can be executed by the processor, and the processor executes the computer-executable instructions to implement the above-mentioned automatic rotation method of the turnout.

[0036] In a third aspect, the present invention further provides an automatic turnout rotation system, comprising:

[0037] Turnouts, which are set between different tracks;

[0038] A switch-out machine is arranged at one end of the turnout; a sensor is arranged on the switch-out machine, and the sensor is used to judge whether the turnout is closely attached, thereby obtaining the indication information of the turnout;

[0039] Monitoring system, used to monitor the turnout's rotation operation process in real time;

[0040] The dispatching system is used to control the rotation of the turnout;

[0041] The interlocking system comprises: a control console and the above-mentioned operation mechanism; the control console is used for human-computer interaction; the operation mechanism transmits signals with the monitoring system and the dispatching system, receives the turnout dispatching command sent by the dispatching system, and sends prompt information and alarm information to the dispatching system and the monitoring system; the operation mechanism transmits signals with the turnout machine, receives the turnout indication information sent by the turnout machine, and can send a turnout moving command to the turnout machine to realize the above-mentioned automatic turnout turning method.

[0042] Compared with the prior art, the technical solution of the present invention has at least the following beneficial effects:

[0043] The automatic turning method of the turnout of the present invention can automatically control the turning machine to turn the turnout by judging whether the turnout meets the conditions for the turnout action, so that the turnout can automatically turn to a specified position; the logical operation of the automatic turning process of the turnout is completely realized by the interlocking system, without the need for manual access, thereby improving the automation level in the field of rail transportation and reducing the workload of operators.

[0044] In the automatic rotation method of the turnout described in the present invention, the automatic rotation attribute of the turnout can be set as needed, and the interlocking system can determine whether the turnout meets the turnout moving condition (i.e., the condition for the turnout action) based on the automatic rotation attribute, making the automatic rotation method described in the present invention more flexible in practical applications.

[0045] In the automatic rotation method of the turnout described in the present invention, a delayed countdown for automatic rotation can be set according to project needs, so that the turnout can execute the switch movement command after the delayed countdown for automatic rotation ends to complete the turnout rotation action, thereby preventing the turnout from automatically rotating due to the conditions for the turnout action being met immediately after being operated to the reverse position, thereby preventing the train from being unable to pass the turnout normally, thereby ensuring the reliability of the automatic rotation system.

[0046] The maximum action time and alarm delay are set in the automatic rotation method described in the present invention to prevent the risk of damage to the motor caused by the switch machine still executing the switch movement command when the switch cannot be rotated into place (i.e., rotated to the positioning position) for some reason, thereby ensuring the safety of the automatic rotation system described in the present invention.

[0051] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] For train tracks with switches, when the switches deviate from the normal position or safe position for some reason, they need to be adjusted to the normal position or safe position in time to ensure the safety of train travel. Figure 1 As shown, a safety line is provided in parallel with the first track on which the train 1 is running, which the train 1 can enter when it enters the route prepared for other trains. To ensure the running safety of the train 1, the position of the switch AB is set to the normal position (or safety position) of the switch AB, i.e., the positioning position, when the train 1 passes through the switch AB and drives towards the safety line, and the position of the switch AB is set to the reverse position when the train 1 passes through the switch AB and still drives in the original direction; and a signal S1 is provided at one end of the safety line. When the train 1 is located outside the signal S1 (i.e., Figure 1 When the train 1 passes the turnout AB in the reverse position (i.e., the train 1 travels from the signal S1 on the safety line to the first track), the turnout AB is operated to the reverse position and locked by the interlocking system until the train 1 passes the turnout AB in the sequence of occupying the route section, unlocks the turnout AB, and operates the turnout AB to the positioning position again. In the prior art, the position of the turnout needs to be operated manually, which consumes a lot of manpower and there is a situation where the response is not timely.

[0055] The present invention provides an automatic turnout system for realizing automatic turnout. The automatic turnout system comprises: an interlocking system, a monitoring system, a dispatching system, a turnout and a turnout machine. The turnout is arranged between different tracks and can change the direction of train travel. The turnout machine is arranged at one end of the turnout and is used to operate the turnout to a positioning position or a reverse position; and a sensor is provided on the turnout machine, which determines whether the turnout is closely attached by the sensor, and then obtains the representation information of the turnout. The monitoring system is used to monitor the turnout rotation operation process in real time, and promptly remind the operator to deal with abnormal situations on site. The dispatching system can send a turnout dispatching command to regulate the rotation of the turnout. The interlocking system includes a control console and an operation mechanism. The control console is a host computer (MMI) used for human-computer interaction, which can display the operating status of the turnout in real time and can also manually operate the position of the turnout; the operation mechanism is a lower computer, which transmits signals with the monitoring system and the dispatching system, can receive the dispatching command to the turnout sent by the dispatching system, and send prompt information and alarm information to the dispatching system and the monitoring system to update the operating status of the turnout in the dispatching system and the monitoring system, and timely feedback to the operator; the operation mechanism transmits signals with the transfer machine, can receive the turnout representation information sent by the transfer machine, and realize the process of the interlocking system collecting the turnout representation information; and the operation mechanism can send a turnout movement command to the transfer machine, control the transfer machine to execute the turnout movement command, and then realize the rotation of the turnout; the operation mechanism transmits signals with the control console, receives manual operation instructions, and enables the turnout to be manually controlled.

[0056] Wherein, the indication information is used to indicate that the turnout is in the reverse position or the positioning position, and includes: positioning indication information and reverse position indication information, wherein the positioning indication information indicates that the turnout is in the positioning position, and the reverse position indication information indicates that the turnout is in the reverse position. And the positioning indication information and the reverse position indication information are both binary variables, and the three states of the turnout can be indicated by the positioning indication information and the reverse position indication information: when the positioning indication information is 1 and the reverse position indication information is 0, it indicates that the turnout is in the positioning position; when the reverse position indication information is 1 and the positioning indication information is 0, it indicates that the turnout is in the reverse position; when the positioning indication information is 0 and the reverse position indication information is 0, it indicates that the turnout is in the lost state.

[0057] like Figure 2 and Figure 3 As shown, the present invention provides an automatic rotation method of a turnout, which is implemented by using the above-mentioned operation mechanism. By setting an automatic rotation countdown, the turnout AB can automatically rotate to the positioning position after being in the reverse position, thereby reducing manual operation and improving the reliability and safety of turnout operation. The automatic rotation method includes:

[0058] Step S1, determining whether the turnout meets the automatic rotation inspection conditions.

[0059] Step S11, setting the automatic rotation attribute of the turnout so that the turnout can start the automatic rotation function.

[0060] According to the project requirements, the automatic rotation mark (ICON) of the turnout is set through the interlocking system to enable the turnout to have the automatic rotation function.

[0061] During the automatic rotation of the turnout, the interlocking system identifies whether the turnout has an automatic rotation mark (ICON), and the automatic rotation attribute can be set for the turnout with the automatic rotation mark.

[0062] The interlocking system sets the attribute of the turnout that deviates from the normal position as an automatic rotation attribute. According to the needs of the project, the automatic rotation attribute of the turnout in the positioning position or the reverse position can be set by the computing mechanism of the interlocking system (i.e., the lower computer); at the same time, the computing mechanism of the interlocking system determines whether it is in the positioning position or the reverse position by collecting the representation information of the turnout, and then determines whether to turn on the automatic rotation function of the turnout. Usually, the positioning position of the turnout is set to the normal position, so the automatic rotation attribute of the turnout in the reverse position is set by the interlocking system. At this time, if the turnout is in the reverse position, the automatic rotation function is turned on, and it automatically rotates from the reverse position to the positioning position and executes step S12; when the turnout is in the positioning position, no operation is performed.

[0063] In another embodiment, the reverse position of the switch can be set to the normal position according to actual needs, and the automatic rotation property of the switch in the positioning position can be set through the operation mechanism of the interlocking system. At this time, if the switch is in the positioning position, the automatic rotation function is turned on to make the switch automatically rotate from the positioning position to the reverse position.

[0064] The automatic rotation attribute includes: a delay countdown T_YS for the automatic rotation of the turnout, and the delay countdown T_YS for the automatic rotation of the turnout is used to make the turnout stay at the original position for a period of time before automatically rotating.

[0065] Step S12, determining through the interlocking system whether the turnout positioning operation satisfies the turnout action condition check.

[0066] The computing mechanism of the interlocking system receives and collects the indication information of the turnout, and determines whether the turnout is in the reverse position based on the indication information. When the turnout is rotated to the reverse position for some reason, the interlocking system receives the reverse indication information sent by the turnout, and at the same time turns on the automatic rotation function of the turnout, and performs a condition check on the turnout action. Among them, the situation in which the turnout is rotated to the reverse position includes at least: the turnout needs to be in the reverse position due to the train route requirements; the turnout needs to be operated to the reverse position alone due to track debugging; in urban rail projects, Y-type turnouts (i.e. double-opening turnouts) are usually used in combination with a group of double-action turnouts and a group of single-action turnouts, so that the train can enter any two directions from the main line direction. When a train route passes through the positioning position of a group of single-action turnouts of the Y-type turnout, the double-action turnout protection needs to be operated and locked to the reverse position.

[0067] Specifically, the operation mechanism of the interlocking system confirms that the turnout is authorized for the rotation operation by receiving the indication information of the turnout (i.e., the reverse position indication information) and the turnout dispatching command sent by the dispatching system (CTC / ATS), and begins to determine whether the turnout meets the conditions for the turnout action (i.e., the turnout moving conditions). Among them, the turnout dispatching command indicates that the dispatching system allows the turnout to be operated to the positioning position.

[0068] The conditions for the switch action include: the switch is not in a blocked state, the switch is not in a single locked state, the switch is not in a locked state, and the switch has not received an operation command to the positioning position or is in the positioning operation process. When the interlocking system determines that the switch meets the above switch action conditions, it indicates that the switch has reached the requirements for the rotation operation, and executes step S2 to perform a delay countdown T_YS for the automatic rotation of the switch; when any of the switch action conditions is not met, the operation cycle of this round of the interlocking system is terminated (i.e., if Figure 3 As shown, the interlocking system completes the time for checking the conditions of a turnout action once), and continues to judge whether the turnout meets the conditions for turnout action in each subsequent operation cycle of the interlocking system until the above-mentioned turnout action conditions are met.

[0069] Among them, the blocking state of the turnout prohibits trains from approaching the turnout, and only single operation is allowed; the single locking state of the turnout manually locks the turnout in a specified position; the locked state of the turnout prohibits any form of operation of the turnout. Please refer to the "Technical Conditions for Computer Interlocking".

[0070] Furthermore, the situations in which the turnout is not in a locked state include: the turnout is not in an approach locking state in a reverse position, the track section where the turnout is located is not occupied, the turnout is not locked for protection, the turnout is not deadlocked or non-approach locked, and in an urban rail project, the turnout is not locked for continuous protection (overlap).

[0071] Step S2, delay countdown of automatic turnout rotation is performed through the interlocking system.

[0072] After the interlocking system determines that the turnout operation meets the turnout action condition check, the delay countdown T_YS of the turnout automatic rotation is started. At this time, the turnout remains in the original position, and the interlocking system will continue to check the turnout action condition during the delay countdown of the turnout automatic rotation. Among them, the automatic rotation countdown can be set according to the needs of the project, which is used to prevent the turnout from automatically rotating as soon as it is operated to the reverse position and immediately meets the turnout action conditions, resulting in the turnout being unable to stay in the reverse position to meet the needs of normal train travel or operator track debugging.

[0073] The interlocking system will complete the condition check of the turnout action in each operation cycle of the interlocking system during the delay countdown T_YS of the automatic turnout rotation, and determine whether the turnout meets the conditions for the turnout action in the operation cycle of the interlocking system.

[0074] When the turnout meets the turnout action condition in an interlocking system operation cycle during the delay countdown T_YS of the turnout automatic rotation, the interlocking system will send the prompt information of the condition check of the turnout action in the operation cycle of the interlocking system to the monitoring system and the dispatching system. The prompt information is used to reflect whether the turnout meets the turnout action condition in the operation cycle of the interlocking system, so as to prompt the operator of the result of the condition check of the turnout action in each interlocking system operation cycle in the delay countdown T_YS of the turnout automatic rotation.

[0075] Further, if the turnout meets the conditions for turnout action in each interlocking cycle during the delay countdown T_YS of the automatic rotation of the turnout (i.e., the operator does not send other operation instructions to the turnout within the delay countdown T_YS of the automatic rotation of the turnout), the interlocking system sends the prompt information the same number of times as the number of interlocking system cycles included in the delay countdown T_YS of the automatic rotation of the turnout. The prompt information will continue to be sent until the delay countdown T_YS of the automatic rotation of the turnout ends, and step S3 is executed through the interlocking system to send a turnout movement command to the switching and withdrawing machine.

[0076] When there is an interlocking cycle during the delay countdown of the automatic rotation of the turnout and the turnout does not meet the turnout action conditions, the interlocking system will immediately stop the delay countdown T_YS of the automatic rotation of the turnout and end the automatic rotation process of the turnout (i.e., turn off the automatic rotation function of the turnout).

[0077] Step S3: the interlocking system sends a switch movement command to the switch-removing machine to drive the switch to rotate to the positioning position.

[0078] After the delay countdown for the automatic rotation of the turnout ends and the interlocking system checks that the turnout still meets the conditions for turnout action, the interlocking system will send a turnout movement command to the positioning position to the turnout machine that controls the turnout rotation, controlling the turnout to complete the rotation action from the reverse position to the positioning position.

[0079] At this time, the interlocking system should continue to keep the switch movement command valid so that it can drive the switch back to the positioning position.

[0080] Step S4, the interlocking system collects the indication information of the turnout and feeds back the execution status of the turnout moving command.

[0081] The maximum action time T_DCQD and alarm delay T_JC are set in the interlocking system. The maximum action time T_DCQD is the maximum time for the turnout to continue operating, which is used to reflect whether the turnout can complete the rotation action normally; the alarm delay T_JC is the reliable time for the interlocking system to collect the turnout information; and the settings of the maximum action time T_DCQD and the alarm delay T_JC are determined by the model of the turnout machine.

[0082] When the interlocking system sends a switch movement command, the countdown of the maximum movement time will start, and the switch representation information will be continuously sent to the monitoring system and the dispatching system. At this time, the interlocking system sends the switch representation information to the monitoring system and the dispatching system and synchronizes the countdown of the maximum movement time.

[0083] Specifically, when the interlocking system starts the countdown of the maximum action time T_DCQD, the timing starts from the time when the switch-removing machine executes the switch-moving command. When it is within the maximum action time T_DCQD and the switch-removing machine executes the switch-moving command normally, the interlocking system will send the switch indication information to the monitoring system and the dispatching system, and make the monitoring system and the dispatching system synchronously display the countdown of the maximum action time T_DCQD; at this time, if within the maximum action time T_DCQD, the interlocking system collects the turnout positioning indication information as 1 and the reverse position indication information as 0, it means that the turnout has been rotated to the positioning position, that is, the turnout has completed the automatic rotation; the interlocking system sends the turnout indication information (i.e., positioning indication information) at this time to the monitoring system and the dispatching system, and stops the maximum action time T_DCQD countdown synchronously displayed by the monitoring system and the dispatching system, indicating that the turnout has completed the automatic rotation process.

[0084] When the maximum action time T_DCQD is exceeded and the interlocking system fails to collect the position information of the turnout, it means that the switch machine has stopped working for some reason, and the interlocking system immediately stops the countdown of the maximum action time T_DCQD. At this time, if the switch machine re-executes the switch command within the maximum action time T_DCQD, the interlocking system will restart the countdown of the maximum action time T_DCQD; if the switch machine still cannot execute the switch command after the countdown of the maximum action time T_DCQD ends, in order to protect the outdoor switch machine from being damaged due to long-term continuous action, the interlocking system will stop maintaining the validity of the switch command and stop the monitoring system and the dispatching system from synchronously displaying the countdown of the maximum action time T_DCQD; at the same time, when the interlocking system collects that the turnout is in a lost state, the interlocking system will start the countdown of the alarm delay T_JC, and send an alarm message to the monitoring system and the dispatching system after the countdown of the alarm delay T_JC ends. The alarm message is used to reflect that the turnout is in a lost state (i.e., a squeezed state) to remind the operator to handle it.

[0085] Among them, after the interlocking system sends the switch movement command, the situation where the switch does not meet the switch movement conditions for some reason includes: the switch is in a lost state due to incomplete movement, that is, the switch is neither in the reverse position nor in the positioning position. At this time, the interlocking system will no longer trigger the automatic rotation function to prevent the switch from being damaged by triggering the automatic rotation function multiple times when the switch cannot be operated normally due to a fault.

[0086] In addition, the present invention also provides a computing mechanism, including a processor and a computer-readable storage medium. The computer-readable storage medium stores computer-executable instructions that can be executed by the processor, and the processor executes the computer-executable instructions to implement the above-mentioned automatic rotation method of the turnout. In summary, the present invention determines whether the turnout meets the conditions for the turnout action through the interlocking system, and uses the delayed countdown of the automatic rotation of the turnout to allow the turnout to stay in the original position for a period of time before performing the rotation action, and automatically controls the turnout to rotate the turnout, so that the turnout can automatically rotate to the specified positioning position, and realize the automatic rotation of the turnout under the condition of ensuring the normal passage of the train or the single operation of the turnout, thereby improving the automation level in the field of rail transit and reducing the work intensity of the operator; at the same time, the present invention sets the maximum action time and alarm delay through the interlocking system to prevent the motor of the turnout from being damaged for some reason, thereby ensuring the safety and reliability of the automatic rotation system.

A method for automatically rotating a turnout, characterized in that: Include: The interlocking system sets the attribute of the turnout that deviates from the normal position as the automatic rotation attribute, and determines whether the turnout with the automatic rotation attribute meets the conditions for the turnout action; After the turnout with automatic rotation attribute meets the turnout action conditions, the interlocking system starts the delay countdown of the turnout automatic rotation, and continuously determines whether the turnout with automatic rotation attribute meets the turnout action conditions during the delay countdown of the turnout automatic rotation; When the delay countdown for the automatic turnout rotation ends and the turnout still meets the turnout action conditions, the interlocking system controls the turnout to complete the rotation action.

2. The automatic turning method of a turnout according to claim 1, characterized in that: The positioning position of the turnout is set to the normal position, and the interlocking system sets the attribute of the turnout in the reverse position to the automatic rotation attribute; or, the reverse position of the turnout is set to the normal position, and the interlocking system sets the attribute of the turnout in the positioning position to the automatic rotation attribute.

3. The automatic turning method of a turnout according to claim 2, characterized in that: The situation where the turnout rotates to the reverse position includes at least: The train route requires that the turnout be in the reverse position; Due to the need for track debugging, the turnout needs to be operated to the reverse position alone; Because the train passes through the positioning position of a set of single-action turnouts of the Y-type turnout, it is necessary to operate the protection of another set of double-action turnouts of the Y-type turnout and lock them to the reverse position.

4. The automatic turning method of a turnout according to claim 2, characterized in that: The conditions for the switch action include: the switch is not in a blocked state, the switch is not in a single locked state, the switch is not in a locked state, and the switch has not received an operation command to a positioning position or is in a positioning operation process.

5. The automatic turning method of a turnout according to claim 4, characterized in that: The situations in which the turnout is not in a locked state include: the turnout is not in an approach locking state in a reverse position, the track section where the turnout is located is not occupied, the turnout is not protectively locked, the turnout is not deadlocked or non-approach locked, and in an urban rail project, the turnout is not continuously protectively locked.

6. The automatic turning method of a turnout according to claim 4, characterized in that: The method for the interlocking system to determine whether the turnout meets the turnout action conditions includes: If any of the switch action conditions are not met, the interlocking system will continue to determine whether the switch action conditions are met in each operation cycle until the switch meets the switch action conditions; The operation cycle of the interlocking system is the time it takes for the interlocking system to complete a condition check of a turnout action.

7. The automatic turning method of a turnout according to claim 6, characterized in that: The method of the interlocking system continuously judging whether the turnout with automatic rotation attribute meets the turnout action condition within the delay countdown of the turnout automatic rotation includes: When the turnout meets the turnout action condition in an operation cycle of the interlocking system during the delay countdown of the turnout automatic rotation, the interlocking system will send the prompt information of the turnout action condition check in the operation cycle of the interlocking system to the monitoring system and the dispatching system; When the turnout does not meet the turnout action conditions in an interlocking cycle during the delay countdown of the turnout automatic rotation, the interlocking system will immediately stop the delay countdown of the turnout automatic rotation and end the turnout automatic rotation process; The prompt information is used to reflect whether the turnout meets the turnout action conditions in the operation cycle of the interlocking system.

8. The automatic turnout rotation method according to claim 1, characterized in that: The method for the interlocking system to control the turnout to complete the rotation action includes: After the delay countdown for the automatic rotation of the turnout ends and the interlocking system checks that the turnout still meets the conditions for turnout action, the interlocking system will send a turnout movement command to the positioning position to the turnout machine that controls the turnout rotation, and keep the turnout movement command valid continuously.

9. The automatic turning method of a turnout according to claim 8, characterized in that: Also includes: The turnout is acquired through the interlocking system to complete the rotation action; Among them, the method of obtaining the situation of the turnout completing the rotation action through the interlocking system includes: Setting a maximum action time in the interlocking system, the maximum action time being the maximum time for which the turnout can be continuously operated; When the interlocking system sends a switch command, the countdown of the maximum action time will start, and the maximum action time will start from the time when the switch-away machine executes the switch command; When the maximum action time is within and the switch-removing machine executes the switch-moving command normally, the interlocking system will send the switch indication information to the monitoring system and the dispatching system, and make the monitoring system and the dispatching system synchronously display the countdown of the maximum action time; If within the maximum action time, the interlocking system collects the turnout indication information as positioning indication information, the turnout completes automatic rotation; at this time, the interlocking system sends the turnout's positioning indication information to the monitoring system and the dispatching system, and stops the countdown of the maximum action time synchronously displayed by the monitoring system and the dispatching system.

10. The automatic turning method of a turnout according to claim 9, characterized in that: The method for obtaining the situation that the turnout completes the rotation action through the interlocking system also includes: When the maximum action time is exceeded and the interlocking system fails to collect the position information of the turnout, the interlocking system will immediately stop the countdown of the maximum action time; If the switch command is executed again during the maximum action time, the interlocking system will restart the countdown of the maximum action time. If the switch-out machine still cannot execute the switch-out command after the countdown of the maximum action time ends, the interlocking system will stop maintaining the validity of the switch-out command, and stop the monitoring system and the dispatching system from synchronously displaying the countdown of the maximum action time; at the same time, after the interlocking system collects that the switch is in the lost meter state, the interlocking system will start the countdown of the alarm delay, and send an alarm message to the monitoring system and the dispatching system after the countdown of the alarm delay ends, to remind the operator to handle it; The alarm information is used to reflect that the switch is in a lost meter state.

11. A computing mechanism comprising a processor and a computer-readable storage medium, characterized in that: The computer-readable storage medium stores computer-executable instructions that can be executed by the processor, and the processor executes the computer-executable instructions to implement the automatic turning method of a turnout according to any one of claims 1 to 10.
