[0035] With the development of society, subways are running more and more frequently. During subway operation, accurate train stop time has a great impact on train driving safety, platform door opening and closing processing, and normal train operation plan. When turning back and changing ends, since it involves train changing ends, higher requirements are put forward for the stop timing of the automatic train operation system ATO.

The embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

A control device may be respectively provided in the head end 101 and the tail end 102, for example, the head end 101 may be provided with a control device C_equip_1, and the tail end 102 may be provided with a control device C_equip_2. In some embodiments, the first control device located at one end of the train may be the control device C_equip_1 in the head end 101; in other embodiments, the first control device located at one end of the train may also be the control device C_equip_2 in the tail end 102. The following embodiments of the present application are all described by taking the first control device being the control device C_equip_1 in the head end 101 and the second control device being the control device C_equip_2 in the tail end 102 as an example. In the embodiments of the present application, when the first control device is the control device C_equip_1 in the head end 101 and the second control device is the control device C_equip_2 in the tail end 102, the first control device can be recorded as the first control device C_equip_1 and the second control device can be recorded as the second control device C_equip_2. Figure 1 , applied to the first control device C_equip_1 located at one end of the train 100; if an arrival terminal change instruction is received, the stop common information is periodically transmitted between the train automatic protection system ATP and the second control device C_equip_2 located at the opposite end; the stop common information includes the stop cycle information determined by the control device that sends the stop common information; the arrival terminal change instruction includes the stop duration; the arrival terminal change instruction can be sent by the train automatic monitoring system ATS; every time the stop common information is received, if the train has stopped at the target station Stop_target, then based on the activation status information of the train, it is determined whether the first control device is an activated end; if it is determined that the first control device is an activated end, the stop timing is performed based on the stop duration; if the first control device is an activated end, and the stop timing duration is equal to the stop duration, the train is executed to exit the station at the target station Stop_target.

[0039] Combine the following Figure 1 The application scenario described herein is used with reference to the accompanying drawings to describe the method for stop timing of an exemplary embodiment of the present application. It should be noted that the above application scenario is only shown to facilitate understanding of the method and principle of the present application, and the implementation of the present application is not limited in this regard.

[0040] The embodiment of the present application provides a method for timing a stop, which is applied to a first control device C_equip_1 located at one end of a train 100; Figure 2 As shown, the following steps may be included:

[0041] S201, if an arrival terminal change instruction is received, the stop public information is periodically transmitted between the automatic train protection system ATP and the second control device at the other end; the stop public information includes the stop cycle information determined by the control device sending the stop public information; the arrival terminal change instruction includes the stop duration.

[0042] In specific implementation, the terminal change instruction at the station can be sent by the train automatic monitoring system. If the terminal change instruction at the station is received, the first control device at one end of the train periodically transmits the stop common information between the train automatic protection system ATP and the second control device at the other end; the stop common information includes the stop cycle information determined by the control device that sends the stop common information; the terminal change instruction at the station includes the stop duration.

[0043] Exemplarily, if the arrival change end instruction Change_ is received, the stop public information Stop_info is periodically transmitted between the train automatic protection system ATP and the second control device C_equip_2 located at the other end; the stop public information Stop_info includes the stopped cycle information stay_cycle_in determined by the control device that sends the stop public information Stop_info; the arrival change end instruction Change includes the stop duration S_time_l.

[0044] S202: Whenever public stop information is received, if the train has stopped at the target station, determine whether the first control device is an activated terminal based on the activation status information of the train.

[0045] In a specific implementation, each time the first control device at one end of the train receives public information about a stop, if the train has stopped at a target station, it determines whether the first control device is an activated end based on the activation status information of the train.

[0046] The activation status information of the train includes the head end key activation status and the tail end key activation status. The head end key activation status is used to indicate whether the head end key has activated the head end so that the head end is the end that controls the train; the tail end key activation status is used to indicate whether the tail end key has activated the tail end so that the tail end is the end that controls the train. At any time point, at most one of the head end and the tail end of the train is activated by the key.

[0047] Exemplarily, when the first control device C_equip_1 at one end of the train 100 receives the stop public information Stop_info, if it is determined that the train 100 has stopped at the target station Stop_target, it determines whether the first control device C_equip_1 is an active end based on the activation status information Active_info of the train 100.

[0048] S203: If it is determined that the first control device is an activated terminal, a stop timing is performed based on the stop duration.

[0049] In specific implementation, each time the first control device located at one end of the train receives public information about a stop, if it is determined that the train has stopped at the target station, it determines whether the first control device is an activated end based on the activation status information of the train. After that, if it is determined that the first control device is an activated end, the stop timing is performed based on the stop duration.

[0050] Exemplarily, if it is determined that the first control device C_equip_1 is the active end, the stop timing is performed based on the stop duration S_time_1.

[0051] S204: If the first control device is an activated end and the stop timing duration is equal to the stop duration, the train exit operation is executed.

[0052] In specific implementation, in step S203, if it is determined that the first control device is an activated terminal, the stop timing is performed based on the stop duration to obtain the stop timing duration of the first control device. After that, if the first control device is an activated terminal and the stop timing duration is equal to the stop duration, the train exit operation is performed. The stop timing duration is the time information obtained by performing stop timing based on the stop duration after determining that the first control device is an activated terminal.

[0053] Exemplarily, if the first control device C_equip_1 is an activated terminal and the stop counting duration St_count_time is equal to the stop duration S_time_1, the exit operation of the train 100 is executed.

[0054] In the above process, it is applied to the first control device located at one end of the train; if an arrival terminal change instruction is received, the stop public information is periodically transmitted between the train automatic protection system ATP and the second control device located at the opposite end, wherein the stop public information includes the stop cycle information determined by the control device that sends the stop public information; the arrival terminal change instruction includes the stop duration; each time the stop public information is received, if the train has stopped at the target station, it is determined whether the first control device is an activated end based on the activation status information of the train; if it is determined that the first control device is an activated end, the stop timing is performed based on the stop duration; if the first control device is an activated end, and the stop timing duration is equal to the stop duration, the train's exit operation is executed. The method of this embodiment can transmit part of the information required for stop timing through the on-board automatic train protection system ATP, provide a mechanism for the fusion processing of the stop timing time at both ends of the train, realize the stop timing by the train control device during the end change process, and control the train's exit operation based on the stop timing duration of the control device as the activation end, which can avoid the failure to complete the stop timing normally in complex scenarios such as ATS communication anomalies, effectively improve the accuracy of the stop timing in the return end change process, and improve the operating efficiency of the train.

[0055] In some embodiments of the present application, the control devices at the head and tail ends of the train do not communicate, and the first control device at one end of the train transmits the stop cycle information to the second control device at the other end through ATP head-to-tail communication; if the first control device is currently the activated end, the stop timing of the first control device does not use the received stopped cycle information, but executes the following process: if it is determined that there is recorded valid stopped cycle information, the stop timing continues with the recorded valid stopped cycle information; if there is no recorded valid stopped cycle information, the stop timing starts from zero according to the stop.

[0056] In some embodiments of the present application, if it is determined that the first control device is an activation end, after performing stop timing based on the stop duration, before executing the train exit operation, the method further includes:

[0057] Based on the stop timing duration, the stop cycle information included in the stop public information sent by the first control device to the second control device at the opposite end is generated.

[0058] In some embodiments of the present application, when executing step S203, the stop timing is performed based on the stop duration, such as Figure 3 As shown, this is achieved through the following steps:

[0059] S301, if there is target stopped station cycle information, and the target stopped station time has not reached the stop time, then the stop time is continued based on the target stopped station cycle information.

[0060] The target stopped station cycle information is the stopped station cycle information recorded by the first control device and is not an invalid value; the target stopped station time is the length of time the train corresponding to the target stopped station cycle information stays at the target station.

[0061] In specific implementation, the invalid value may be a preset information value representing that the value is invalid. The information value may be a value that does not meet the preset conditions. For example, the invalid value may be set to a negative number. For example, the invalid value may be set to "-1". In the time period before the stop timing is started, the information on the stopped period included in the stop public information transmitted between the first control device through the automatic train protection system ATP and the second control device at the opposite end may be an invalid value, such as "-1". In some embodiments of the present application, the invalid value is the FF value. In other embodiments of the present application, the invalid value is a null value.

[0062] In some embodiments of the present application, the stopped station cycle information may be a stopped station cycle count, and the value of the stopped station cycle count is a natural number. The stopped station cycle count represents the number of operation cycles that have passed after the stop timing is started. The stop timing is in operation cycles. The length of the operation cycle can be configured as needed, for example, the operation cycle can be set to 50ms.

[0063] For example, in the process of performing stop timing based on the stop duration, if there is target stopped cycle information T_stay_cycle_in, and the target stopped time Tar_a_S_time has not reached the stop duration S_time_1, then the stop timing is continued based on the target stopped cycle information T_stay_cycle_in. The target stopped cycle information T_stay_cycle_in is the stopped cycle information that is not an invalid value recorded by the first control device C_equip_1 for stop timing; the target stopped time Tar_a_S_time is the time that the train 100 corresponding to the target stopped cycle information T_stay_cycle_in has stayed at the target station Stop_target.

[0064] S302: If there is no target station stop cycle information, then the stop timing is started based on the stop time when the train stops at the target station.

[0065] Exemplarily, if there is no target stopped cycle information T_stay_cycle_in, the stop timing starts based on the stop time Stop_target_time when the train 100 stops at the target station Stop_target.

[0066] In some embodiments of the present application, after determining whether the first control device is an activated end based on the activation status information of the train, if the first control device is determined to be an inactivated end, stop timing is performed based on the first stopped cycle information that is not an invalid value and is sent when the second control device was most recently an activated end.

[0067] The embodiment of the present application provides another method for timing a stop, which is applied to a first control device located at one end of a train, such as Figure 4 As shown, the following steps are included:

[0068] Step S401: If a command to change terminals at a station is received, the public information of the station stop is periodically transmitted between the automatic train protection system ATP and the second control device at the other end.

[0069] The public information about the stop includes the information about the stop cycle determined by the control device that sends the public information about the stop; and the terminal change instruction at the station includes the duration of the stop.

[0070] Step S402: Whenever the stop public information is received, if the train has stopped at the target station, it is determined whether the first control device is an activation terminal based on the activation status information of the train.

[0071] Step S403: If it is determined that the first control device is an activated terminal, the stop timing is performed based on the stop duration.

[0072] Step S404: If it is determined that the first control device is an inactive terminal, stop timing is performed based on the first stop cycle information that is not an invalid value and is sent when the second control device is most recently an active terminal.

[0073] In a specific implementation, each time the first control device located at one end of the train receives public information about a stop, if it is determined that the train has stopped at the target station, it determines whether the first control device is an activated end based on the activation status information of the train. After that, if it is determined that the first control device is an inactivated end, the stop timing is performed based on the first stopped cycle information that is not an invalid value and sent when the second control device was most recently an activated end.

[0074] Exemplarily, if it is determined that the first control device C_equip_1 is an inactive terminal, the stop timing is performed based on the first stop cycle information that is not an invalid value and is sent when the second control device C_equip_2 is most recently an active terminal.

[0075] Step S405: If the first control device is an activated terminal and the stop timing duration is equal to the stop duration, the train exit operation is executed.

[0076] In some embodiments of the present application, when executing step S404, the process of stopping timing is performed based on the first stopped period information that is not an invalid value sent when the second control device is the last activated end, such as Figure 5 As shown, this is achieved through the following steps:

[0077] S501, if it is determined based on the activation status information that the second control device is currently the activation end, then the stop timing is performed with the first stopped station cycle information as the starting point; the first stopped station cycle information is the first stopped station cycle information that is not an invalid value and is sent by the second control device after the second control device becomes the activation end this time.

[0078] In specific implementation, if it is determined based on the activation status information of the train that the second control device is currently the activation end, the stop timing is executed with the first stopped station cycle information as the starting point, wherein the first stopped station cycle information is the first stopped station cycle information that is not an invalid value and sent by the second control device after the second control device becomes the activation end this time.

[0079] Exemplarily, if it is determined based on the activation status information Active_info that the second control device C_equip_2 is currently the active end, the stop timing is performed with the first stopped cycle information stay_cycle_in_1 as the starting point; the first stopped cycle information stay_cycle_in_1 is the first stopped cycle information that is not an invalid value and is sent by the second control device C_equip_2 after the second control device C_equip_2 becomes the active end this time.

[0080] S502, if it is determined based on the activation status information that the second control device is currently an inactive end, the stop timing is performed with the second stopped station cycle information as the starting point; the second stopped station cycle information is the first stopped station cycle information that is not an invalid value and is sent by the second control device after the second control device last served as an active end.

[0081] In specific implementation, if it is determined based on the activation status information of the train that the second control device is currently an inactive end, the stop timing is executed with the second stopped cycle information as the starting point, wherein the second stopped cycle information is the first stopped cycle information that is not an invalid value and is sent by the second control device after the second control device last served as an active end.

[0082] Exemplarily, if it is determined based on the activation status information Active_info that the second control device C_equip_2 is currently an inactive end, the stop timing is performed with the second stopped cycle information stay_cycle_in_2 as the starting point; the second stopped cycle information stay_cycle_in_2 is the first stopped cycle information that is not an invalid value and is sent by the second control device C_equip_2 after the second control device C_equip_2 last served as an active end.

[0083] In some embodiments of the present application, the control devices at the head and tail ends of the train do not communicate, and the first control device at one end of the train transmits the stopped period information to the second control device at the opposite end through ATP head-to-tail communication; if the first control device is currently an inactive end, the first control device receives the stopped period information of the opposite end transmitted by ATP head-to-tail communication, and the first control device performs the following process: if the opposite end is determined to be an activated end, the first non-invalid data in the received stopped period information of the opposite end is recorded and the stop timing is started based on this data; if the opposite end is not an activated end, the timing is started based on the valid stopped period information recorded in the first control device; if the data in the received stopped period information of the opposite end and the recorded stopped period information in the first control device are both invalid values, the stop timing is not performed.

[0084] In some embodiments of the present application, considering the communication delay, if the control device is currently an inactive end and receives the information of the station stop period from the opposite active end and it is a valid value, a preset number of operation cycles is added as the communication delay, and the station stop timing is started from this. In some embodiments, the preset number is set to 5, that is, when the control device is currently an inactive end and receives the station stop period information from the opposite active end and it is a valid value, the received station stop period information is increased based on 5 operation cycles.

[0085] In some embodiments of the present application, when executing step S404, the process of stopping timing is performed based on the first stopped period information that is not an invalid value sent when the second control device is the last activated end, such as Figure 6 As shown, this is achieved through the following steps:

[0086] S601, adding preset communication delay cycle information to the first station-stopped cycle information that is not an invalid value and is sent when the second control device is most recently an activated end, to obtain corrected station-stopped cycle information.

[0087] In specific implementation, the stop timing is based on the operation cycle, and the relationship between the communication delay cycle information caused by the communication delay and the operation cycle is pre-calibrated. For example, the communication delay cycle information caused by the communication delay can be calibrated to be 5 operation cycles. Based on this, the first stop cycle information that is not an invalid value sent when the second control device is the last activated end is added with the preset communication delay cycle information to obtain the corrected stop cycle information.

[0088] Exemplarily, the first non-invalid stopped cycle information sent when the second control device C_equip_2 was last activated is added with the preset communication delay cycle information Tr_del_cycle_in to obtain the corrected stopped cycle information, and the corrected stopped cycle information is recorded as the stopped cycle correction value Aj_stay_cycle_in.

[0089] S602, starting from the corrected stop cycle information, executing stop timing.

[0090] Exemplarily, the stop timing is performed with the corrected stop cycle information, that is, the stop cycle correction value Aj_stay_cycle_in, as the starting point.

[0091] The embodiment of the present application provides another method for timing a stop, which is applied to a first control device located at one end of a train; Figure 7 As shown, the following steps are included:

[0092] Step S701: If a command to change terminals at a station is received, the public information of the station stop is periodically transmitted between the automatic train protection system ATP and the second control device at the other end.

[0093] The public information about the stop includes the information about the stop cycle determined by the control device that sends the public information about the stop; and the terminal change instruction at the station includes the duration of the stop.

[0094] Step S702: Whenever the stop public information is received, if the train has stopped at the target station, it is determined whether the first control device is an activation terminal based on the activation status information of the train.

[0095] Step S703: If it is determined that the first control device is an active end, a first judgment is performed to determine whether there is target station stop period information.

[0096] The target stopped station period information is the stopped station period information recorded by the first control device and is not an invalid value.

[0097] Step S704: If the result of the first judgment is that there is target stopped station cycle information and the target stopped station time has not reached the stop time, then the stop time is continued based on the target stopped station cycle information; the target stopped station time is the length of time the train stays at the target station corresponding to the target stopped station cycle information.

[0098] Step S705: If the result of the first judgment is that there is no target station stop cycle information, then the stop timing is started based on the stop time when the train stops at the target station.

[0099] Step S706: If it is determined that the first control device is an inactive terminal, a second judgment is performed to determine whether the second control device is currently an active terminal.

[0100] In a specific implementation, it is determined whether the second control device is currently an activated terminal, specifically, based on the activation state information, whether the second control device is currently an activated terminal

[0101] Step S707, if the result of the second judgment is that the second control device is currently the active end, the stop timing is performed with the first stopped station cycle information as the starting point; the first stopped station cycle information is the first stopped station cycle information that is not an invalid value and is sent by the second control device after the second control device becomes the active end this time.

[0102] Step S708, if the result of the second judgment is that the second control device is not currently an active end, the stop timing is performed with the second stopped station cycle information as the starting point; the second stopped station cycle information is the first stopped station cycle information that is not an invalid value and is sent by the second control device after the second control device last served as an active end.

[0103] Step S709: If the first control device is an activated end and the stop timing duration is equal to the stop duration, the train exit operation is executed.

[0104] In the above embodiment, the first control device located at one end of the train is applied; if the command of changing the end at the station is received, the stop common information is transmitted periodically between the train automatic protection system ATP and the second control device located at the opposite end; the stop common information includes the stop cycle information determined by the control device that sends the stop common information; the command of changing the end at the station includes the stop duration; each time the stop common information is received, if the train has stopped at the target station, it is determined whether the first control device is an activated end based on the activation status information of the train; if it is determined that the first control device is an activated end, the stop timing is performed based on the stop duration; if the first control device is an activated end, and the stop timing duration is equal to the stop duration, the train exit operation is executed. Therefore, in this embodiment, part of the information required for stop timing can be transmitted through the on-board train automatic protection system ATP, providing a mechanism for the fusion processing of the stop timing time at both ends of the train, so that the stop timing is performed by the train control device during the end change process, improving the accuracy of the stop timing in the return end change process, and improving the operation efficiency of the train.

[0105] Based on the same inventive concept, the stop timing method of the present application can also be implemented by a stop timing device. The effect of the stop timing device is similar to that of the above method, and will not be repeated here.
