Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of urban rail transit signal system, and particularly relates to a train point control level adjustment control method and device. BACKGROUND

[0002] The current mainstream urban rail transit signal system train operation control level includes a continuous train control level (CTC), an intermittent train control level (ITC) and an interlocking control level (ILC).

[0003] The CTC level is a main control level, which is based on moving block and can realize small-interval train operation tracking. When the signal system fails to meet the CTC level operation condition, the ITC level operation can be used if the corresponding condition is met. The ITC level is a running control level based on fixed block. When the signal system does not meet the CTC level and the ITC level control level operation, the ILC level is used for operation if the corresponding condition is met. The automation level and the safety protection capability are in descending order of the CTC level, the ITC level and the ILC level. The ITC level requires that the ground device is deployed with an active transponder. The train receives point mobile authorization and other information when passing through the active transponder. The vehicle on-board controller (VOBC) controls the train to operate in the ITC level according to the point mobile authorization and other information.

[0004] However, the ITC level requires that the active transponder is deployed on the ground. The interlocking sends the corresponding transponder message to the active transponder through the LEU device according to the display of the signal machine. The VOBC receives and analyzes the transponder message and updates the front mobile authorization information when the train passes through the active transponder. However, when the active transponder is not deployed on the ground, the urban rail transit signal system does not have the ITC level control function, which greatly affects the safety and operation efficiency of the system and needs to be solved urgently. SUMMARY

[0032] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0033] The train point control level adjustment control method and device provided by the embodiment of the present application are described below with reference to the accompanying drawings. In view of the problems mentioned in the background art, the present application provides a train point control level adjustment control method. In the method, it is determined whether the target train meets the preset interlocking communication condition. If the target train meets the preset interlocking communication condition, the target train is controlled to establish communication with the interlocking. The transponder message of the target homing signal machine sent by the interlocking is received, and the transponder message is parsed to generate parsed data of the transponder message, and the distance between the maximum safe front end of the target train and the target homing signal machine is calculated. Based on the parsed data, it is determined whether the distance between the target train and the target homing signal machine is less than a preset first configuration value, and whether the target train meets a preset train upgrade auxiliary condition. If the distance is less than the preset first configuration value and the target train meets the preset train upgrade auxiliary condition, the target train is controlled to be upgraded to a point train control level. In the present application, when there is no active transponder deployed on the ground, the on-board ATP communicates with the interlocking, the interlocking sends the transponder message to the on-board ATP through wireless communication according to the display of the signal machine, and the on-board ATP operates in the ITC level control level after parsing the message, thereby reducing the deployment of active transponders and LEUs and other devices, reducing the construction cost, and improving the safety and operation efficiency of the urban rail transit signal system. Thus, the problem that the urban rail transit signal system does not have the ITC level control function when there is no active transponder deployed on the ground, which greatly affects the safety and operation efficiency of the system, is solved.

[0034] Specifically, Figure 1 A flowchart of the train point control level adjustment control method provided by the embodiment of the present application is shown in FIG. 1.

[0035] As Figure 1 shown, the train point control level adjustment control method includes the following steps:

[0036] In step S101, it is determined whether the target train meets the preset interlocking communication condition. If the target train meets the preset interlocking communication condition, the target train is controlled to establish communication with the interlocking.

[0037] In actual execution, when there is no active transponder (and active transponder supporting devices such as LEU) deployed on the ground, the embodiment of the present application can first analyze the communication state between the current train and the interlocking, and establish communication when the preset interlocking communication condition is met between the current train and the interlocking, thereby providing technical support for the subsequent transmission of the transponder message.

[0038] Optionally, in one embodiment of the present application, the preset interlocking communication condition comprises: the distance between the maximum safety front end and the target same direction signal machine is less than a second preset configuration value, and the ZC link establishment fails, and the control level in the train pre-selection mode of the target train is the continuous train control level or the point train control level.

[0039] It should be noted that in all areas where the train-ground wireless communication is deployed, the RM needs to establish communication with the interlocking when positioning the train or the ITC level train, that is, the area where the on-board ATP communicates with the CI is not limited to only a few areas with special attributes (in the existing signal system, the on-board ATP communicates with the interlocking only in a few areas with special attributes such as station).

[0040] In the embodiment of the present application, if the current train needs to establish communication with the interlocking, the following interlocking communication conditions need to be met at the same time:

[0041] 1. The distance between the maximum safety front end of the train and the nearest same direction signal machine in front of the train running (i.e., the target same direction signal machine) is less than a configuration value (i.e., a second preset configuration value, which is recommended to be the train length of the train operating in the project);

[0042] 2. The on-board ATP judges that the ZC link establishment fails;

[0043] 3. The control level in the train pre-selection mode is the CTC level or the ITC level.

[0044] Therefore, in the embodiment of the present application, when the on-board ATP judges that the current train meets the interlocking communication condition after the RM mode train is positioned, the corresponding interlocking is established to communicate, thereby improving the reliability of the established communication state and guaranteeing the realization of the transponder message transmission function.

[0045] In step S102, the transponder message of the target same direction signal machine sent by the interlocking is received, and the transponder message is parsed to generate parsed data of the transponder message, and the distance between the maximum safety front end of the target train and the target same direction signal machine is calculated.

[0046] After the target train establishes communication with the interlocking, further, the embodiment of the present application can also receive the transponder message of the nearest same direction signal machine in front sent by the interlocking through the on-board ATP, and perform real-time parsing and calculate the distance between the current maximum safety front end and the same direction signal machine, thereby providing reliable data guidance and basis for the adjustment control of the target train in the point train control level.

[0047] Optionally, in an embodiment of the present application, receiving the transponder message of the target homing signal machine sent by the interlocking includes: obtaining the ID information of the target homing signal machine and sending the ID information to the interlocking; and obtaining and sending the transponder message corresponding to the ID information through the interlocking.

[0048] It should be noted that, after the RM mode train establishes communication with the interlocking, the periodical interaction information of the embodiment of the present application is as follows:

[0049] 1. The on-board ATP sends the ID of the nearest homing signal machine in front of the train to the interlocking.

[0050] 2. The interlocking sends the transponder message corresponding to the signal machine ID sent by the on-board ATP to the on-board ATP.

[0051] Therefore, the embodiment of the present application realizes the periodical interaction of the transponder message between the current train and the interlocking, thereby providing a reliable basis for judging whether the current train needs to be upgraded to the point train control level.

[0052] In step S103, based on the analysis data, it is judged whether the distance between the target train and the target homing signal machine is less than a preset first configuration value and whether the target train satisfies a preset train upgrade auxiliary condition, wherein if the distance is less than the preset first configuration value and the target train satisfies the preset train upgrade auxiliary condition, the target train is controlled to be upgraded to the point train control level.

[0053] After calculating the distance between the maximum safe front end of the target train (i.e. the current train) and the target homing signal machine, further, the embodiment of the present application can also judge, according to the analysis data, whether the distance between the above maximum safe front end and the target homing signal machine is less than a preset first configuration value (the first configuration value can be the shortest length of the train that can be uncoupled in the project), when the on-board ATP judges that the distance between the maximum safe front end of the train and the target homing signal machine is less than the first configuration value, and the current train satisfies other conditions (i.e. the train upgrade auxiliary condition) of upgrading to the ITC level, the current train can be controlled to be upgraded to the ITC level.

[0054] Therefore, the embodiment of the present application analyzes the safety of the region between the current train position and the front signal machine after the on-board ATP receives the transponder message corresponding to the target homing signal machine in front, so as to upgrade the current train to the ITC level when the current train satisfies the safety requirement, thereby effectively guaranteeing the safety performance of the train operation.

[0055] Optionally, in an embodiment of the present application, after the target train is controlled to upgrade to the point train control level, the method further comprises: acquiring and analyzing a new transponder message of the target homing signal machine in real time to generate new analysis data; determining a message information state of the new transponder message according to the new analysis data; if the message information state of the new transponder message is a red light message information state, controlling the target train to retract the MA to the target red light signal machine; and if the message information state of the new transponder message is a yellow light message information state or a green light message information state, controlling the target train to perform a preset extended MA operation.

[0056] In actual execution, when the train is running at the ITC level, the on-board ATP can continuously receive the transponder message of the nearest homing signal machine in front sent by the interlocking, and analyze and process the transponder message in real time to determine the message information state of the transponder message. When the message information state is a red light message information state, the train should be controlled to immediately retract the MA to the red light signal machine. When the message information state is a green light / yellow light message information state, the train should be controlled to immediately extend the MA.

[0057] Therefore, in the process of running the train at the point train control level, the embodiments of the present application control the train to adjust the MA according to the real-time acquisition of the transponder message of the homing signal machine, thereby greatly guaranteeing the safety and reliability of vehicle operation.

[0058] Optionally, in an embodiment of the present application, after the target train is controlled to upgrade to the point train control level, the method further comprises: determining whether the maximum safe front end has passed the target homing signal machine based on the distance between the maximum safe front end and the target homing signal machine; if the maximum safe front end of the target train has passed the target homing signal machine, acquiring the homing signal machine closest to the target train in the direction of travel of the target train, and updating the homing signal machine to a new target homing signal machine, otherwise, not updating the target homing signal machine.

[0059] It should be noted that when the on-board ATP determines that the maximum safe front end has passed the target homing signal machine, the embodiments of the present application need to update the CI to run the nearest homing signal machine in front to the next homing signal machine (i.e. the new target homing signal machine), and the on-board ATP no longer processes the message information of the signal machine that the maximum safe front end has passed sent by the CI.

[0060] Therefore, in the process of running the train at the point train control level, the embodiments of the present application update the signal machine in front, so that the on-board ATP continuously acquires the message state of the effective signal machine in front, realizes the continuity of the on-board ATP acquiring the moving authorization at the ITC level, and makes the train have better safety and higher operation efficiency.

[0061] The execution logic of the train point control level adjustment control method of the present application is described below through a specific embodiment and in conjunction with the accompanying drawings.

[0062] In one specific embodiment of the present application, when the train is in the RM mode and establishes positioning by sequentially passing through two passive transponders, the on-board ATP can establish communication with the interlocking where the train is currently located after meeting the corresponding conditions. After the communication is established, the on-board ATP sends the ID information of the nearest signal machine in the same direction ahead to the interlocking, the interlocking feeds back the transponder message information corresponding to the signal machine, and the on-board ATP judges whether to upgrade to the ITC level according to the transponder message information sent by the interlocking.

[0063] Figure 2 The execution logic of the train point control level adjustment control method is shown in the schematic diagram. As shown in Figure 2 The execution process of the train point control level adjustment control method of the present application is described as follows:

[0064] S201: The RM mode train establishes positioning;

[0065] S202: It is judged whether the on-board ATP meets the condition of establishing communication with the interlocking. If yes, go to S203, otherwise go to S206;

[0066] S203: The on-board ATP establishes communication with the interlocking;

[0067] S204: The on-board ATP sends the ID of the nearest signal machine in the same direction ahead to the interlocking, and the interlocking feeds back the message information of the signal machine to the on-board ATP;

[0068] S205: The on-board ATP judges whether to meet the condition of upgrading to the ITC level. If yes, go to S207, otherwise go to S206;

[0069] S206: Keep the current train in the RM mode;

[0070] S207: Upgrade the current train to the ITC level.

[0071] According to the train point control level adjustment control method provided in the embodiment of the present application, whether the target train meets the preset interlocking communication condition is judged, wherein if the target train meets the preset interlocking communication condition, the target train is controlled to establish communication with the interlocking; the transponder message of the target homing signal machine sent by the interlocking is received, and the transponder message is parsed to generate parsed data of the transponder message, and the distance between the maximum safe front end of the target train and the target homing signal machine is calculated; based on the parsed data, whether the distance between the target train and the target homing signal machine is less than a preset first configuration value and whether the target train meets a preset train upgrading auxiliary condition are judged, wherein if the distance is less than the preset first configuration value and the target train meets the preset train upgrading auxiliary condition, the target train is controlled to be upgraded to a point train control level. When no active transponder is deployed on the ground, the on-board ATP communicates with the interlocking, the interlocking sends the transponder message to the on-board ATP through wireless communication according to the display of the signal machine, and the on-board ATP operates in the ITC level control level after parsing the message, thereby reducing the deployment of active transponders and LEU and other devices, reducing the construction cost, and improving the safety and operation efficiency of the urban rail transit signal system.

[0077] The upgrading module 300 is configured to judge, based on the parsed data, whether the distance between the target train and the target homing signal machine is less than a preset first configuration value and whether the target train meets a preset train upgrading auxiliary condition, wherein if the distance is less than the preset first configuration value and the target train meets the preset train upgrading auxiliary condition, the target train is controlled to be upgraded to a point train control level.

[0084] The second analyzing module is configured to determine whether the maximum safety front end has passed the target homeward signal based on a distance between the maximum safety front end and the target homeward signal after the target train is upgraded to the point train control level.
