and S101, respectively receiving the turnout state and the actual turnout rotation time, wherein the actual turnout rotation time is determined by the turnout health monitoring server according to the turnout health state.
In an implementation, the health state of the turnout comprises: the turnout health monitoring system comprises a health state, a sub-health state and an unhealthy state, wherein the actual turning time of the turnout is determined by a turnout health monitoring server according to the health state of the turnout, and the turnout health monitoring system comprises the following steps:
determining the turnout health state by using a turnout health state model in the turnout health monitoring server;
and determining the actual turning time of the turnout corresponding to different turnout health states by utilizing the matching relationship between the turnout health states and the actual turning time of the turnout.
In the concrete implementation, through the different health status of definition switch, switch health monitoring server can be according to the different health status of definition, confirm the actual rotation time of current switch and send to the train, so that the train can be according to the actual rotation time of switch, apply for switch resource in switch the place ahead in advance, need not to wait for switch action in switch the place ahead and pass through the switch again to the state unanimous with train traffic direction, effectively reduce the occupation of the other resource time of rail, and then promote the train operating efficiency of whole circuit.
Different from the prior art, the signal system sets the turnout operation time to be 13 seconds as the default turnout operation time based on safety consideration, namely when the front train and the rear train in the virtual marshalling train are untrusted and passed through the turnout, the situation that a part of the train in the virtual marshalling train waits in front of the turnout occurs, and the turnout operation time of the turnout in a normal healthy state is 7 seconds. Consequently, the actual rotation time of switch that the present embodiment utilized switch health monitoring server to confirm that different switch health status corresponds sends to the train to make the train can in time apply for the switch resource according to the actual rotation time of switch, avoid waiting for the switch action in switch the place ahead, thereby effectively reduce the occupation of the other resource time of rail, promote the train operating efficiency of whole circuit.
In specific implementation, the turnout health monitoring server determines the actual turnout rotation time corresponding to different turnout health states according to the determined turnout health state and by utilizing the corresponding relation between the turnout health state and the actual turnout rotation time. Specifically, turnout health detection devices and industrial cameras are installed on two sides of a turnout, and periodically acquired turnout switch machine current data and image information which is shot by the industrial cameras and contains turnout stock rails, switch rails and the like are sent to a turnout health monitoring server in real time by using a sending device. The database of the turnout health monitoring server stores a large amount of turnout health detection model data, and turnout health states are divided into healthy, sub-healthy and unhealthy states according to turnout action time of turnouts of different models. The method comprises the steps of establishing a turnout health detection model containing corresponding relation between turnout current data and turnout health states, determining the turnout health states by using the turnout health detection model according to the received turnout current data and image information of turnout switch rails, further calculating time (actual turnout rotation time) required by current turnout rotation, and sending the turnout rotation time to a train.
According to the actual operation scene requirements, the turnout health state determining method comprises the steps of obtaining current curve data of a turnout switch machine by using a turnout health detection device, obtaining image information of a turnout switch blade by using an industrial camera, inputting the current curve data and the image information of the turnout switch blade into a turnout health detection model, and outputting the action time of the turnout by the turnout health detection model by determining the residual service life and the turnout model of the turnout switch machine, so as to determine that the turnout health state is healthy, or sub-healthy, or unhealthy.

Fig. 2 is a schematic diagram of the operation mode of the marshalling train passing through the switch points in the embodiment of the present application, such as (1) and (2) shown in fig. 2, when the virtual marshalling train is in normal operation, the operation paths of the two trains are kept consistent and simultaneously pass through the switch points. Fig. 3 is a schematic view of the same operation mode of the operation path of the train after the disassembly and the compilation, and as shown in fig. 3, for an application scenario in which the paths of the front train and the rear train are the same after the disassembly and the compilation of the train, the difference from fig. 2 is that the front train normally operates, the rear train decelerates, and the operation distance between the two trains becomes longer.
In a specific implementation, as shown in fig. 3(1), if the moving directions (moving paths) of the front and rear cars in the virtual train consist are both consistent with the turnout state (positioning, reverse), the turnout state is kept unchanged, i.e., the turnout does not need to be operated. Specifically, if the turnout state is in the positioning state, and the running direction (running path) of the front and rear vehicles needs the turnout state to be in the positioning state; or, if the turnout state is in the reversal state and the running direction (running path) of the front and rear vehicles needs the turnout state to be in the reversal state, the turnout state is kept unchanged. Therefore, the train set decoding position is independent of the decoding distance from the switch, namely the minimum decoding distance is 0.

if the running directions of the front vehicle and the rear vehicle in the virtual marshalling train are not consistent with the received turnout state, calculating a first minimum distance between the front vehicle and the rear vehicle and the turnout region according to the running speed of the front vehicle and the received actual rotation time of the turnout;
and controlling the front and rear vehicles to perform the decoding in a first decoding area corresponding to the first minimum decoding distance.
In implementation, if the operation direction of the front and rear trains in the virtual marshalling train is not consistent with the received switch state, the step of controlling the front and rear trains to perform the decompiling in the corresponding decompiling area according to the matching relationship between the operation direction of the front and rear trains and the switch state and the actual rotation time of the switch further includes:

In a specific implementation, as shown in fig. 3(2), if the traveling directions (traveling paths) of the front and rear cars in the virtual train consist are not identical to the turnout state, a turnout operation request is sent, that is, the turnout needs to be operated. Specifically, if the turnout state is in a reverse state, and the running direction (running path) of the front vehicle and the rear vehicle needs to position the turnout; or if the turnout state is in a positioning state and the running directions (running paths) of the front and rear cars need to be reversely positioned at the turnout, calculating the first minimum solution distance from the solution position of the marshalling train to the turnout area to be V x T according to the running speed V of the front car and the actual turning time T of the turnout received from the turnout health monitoring server, and controlling the front and rear cars to perform solution in the first solution area corresponding to the first minimum solution distance, so that the front car after solution runs at a constant speed and the rear car runs at a reduced speed.
Meanwhile, according to the obtained judgment result that the running directions of the front vehicle and the rear vehicle in the virtual marshalling train are not consistent with the received turnout state, after the front vehicle is determined to send turnout action requests to the object controller OC, the front vehicle sends turnout action requests to the object controller OC according to the received actual turnout rotation time T from the turnout health monitoring server, so that the object controller OC can control turnout to complete corresponding actions according to turnout action times (the turnout action times are 1) contained in the turnout action requests, and therefore when the front vehicle arrives at a turnout area, the turnout is switched to the corresponding state, therefore, the application time of the turnout action requests is adjusted based on the actual turnout rotation time, and the running efficiency of the whole line can be obviously improved.
In implementation, if the operation direction of the front and rear trains in the virtual marshalling train is not consistent with the received turnout state, the step of controlling the front and rear trains to perform the decompiling in the corresponding decompiling area according to the matching relationship between the operation direction of the front and rear trains and the turnout state and the actual rotation time of the turnout comprises the following steps:
if the operation direction of a front vehicle in the virtual marshalling train is consistent with the received turnout state and the operation direction of a rear vehicle is inconsistent with the received turnout state, calculating a second minimum decommissioning distance between the front vehicle and the rear vehicle and the turnout region according to the operation speed of the front vehicle, the deceleration of the rear vehicle, the operation time of the front vehicle from the operation of the front vehicle to the turnout region and the actual rotation time of the turnout;
and controlling the front and rear vehicles to perform the decoding in a second decoding area corresponding to the second minimum decoding distance.
In implementation, if the operation direction of the front and rear trains in the virtual marshalling train is not consistent with the received switch state, the step of controlling the front and rear trains to perform the decompiling in the corresponding decompiling area according to the matching relationship between the operation direction of the front and rear trains and the switch state and the actual rotation time of the switch further includes:
and if the operation direction of the front train in the virtual marshalling train is consistent with the received turnout state and the operation direction of the rear train is inconsistent with the received turnout state, determining that the turnout action frequency is 1, and sending a turnout action request to the corresponding object controller by the rear train so that the object controller controls the turnout to switch the turnout state after determining that the turnout is cleared from the tail of the front train.
In specific implementation, fig. 4 is a schematic view of different operation modes of operation paths after the marshalling train is disassembled, and for an application scenario that operation paths of front and rear trains are different after the marshalling train is disassembled, as shown in fig. 4, the operation modes of the front and rear trains passing through a turnout are different after the marshalling is disassembled, the front train operates along the positioning direction of the turnout, and the rear train operates along the reverse direction of the turnout; or the front vehicle runs along the reverse direction of the turnout, the rear vehicle runs along the positioning direction of the turnout, namely the front vehicle and the rear vehicle respectively run according to different paths after the railway switch is disassembled, the train needing to act the turnout is determined according to the running directions of the front vehicle and the rear vehicle and the current state of the turnout, and then the determined train sends a turnout action request to the object controller according to the received actual turning time of the turnout, so that the object controller controls the turnout to switch the turnout state.
Fig. 5 is a schematic diagram of a rear car needing turnout operation after the marshalling train is disassembled, if the turnout state is in a positioning state, a front car runs according to the turnout positioning direction, a rear car runs according to the turnout reverse direction, and the train needing turnout operation is determined to be the rear car, the rear car sends a turnout operation request to an object controller, and after the object controller determines that the tail of the front car leaves the turnout zone clearly, the turnout operation is controlled to be in the reverse state, so that the rear car can pass through the turnout area according to the turnout reverse direction.
Specifically, as shown in fig. 5(1), the marshalling train is in the second decommissioning area, which is in the decommissioning critical state, and the inter-vehicle distance between the front and rear trains is S0The vehicle length is L; as shown in fig. 5(2), the operation speed of the front vehicle after the de-compilation is the road speed limit V, and the rear vehicle runs at a reduced speedThe emergency deceleration is a (for ensuring the emergency braking distance of the train), when the front train head runs to the turnout area, the running time of the front train is t, and the running distance is S1V × t; as shown in fig. 5(3), when the object controller determines that the front car tail is out of the switch section, the object controller controls the switch to move to the reverse state, the actual rotation time of the switch is T, and the distance from the second de-encoding area to the switch area of the rear car head is S at this moment2＝V*(T+t)-1/2*a*(t+T)2Wherein S is2＝S1+S0Is arranged to obtain S2＝-1/2*a*t2+(V-a*T)*t+(V*T-1/2*a*T2). Therefore, the actual distance S will be decoded2-(L+S0) And as the second minimum de-coding distance, the actual de-coding distance is the distance from the front car head to the turnout area.
Meanwhile, according to the obtained judgment result that the operation direction of the front train in the virtual marshalling train is consistent with the received turnout state and the operation direction of the rear train is inconsistent with the received turnout state, after the rear train is determined to send a turnout action request to the object controller OC, the rear train sends the turnout action request to the object controller OC according to the received actual turnout rotation time T from the turnout health monitoring server, so that the object controller OC can control the turnout to complete corresponding action according to the turnout action times (the turnout action times is 1) contained in the turnout action request, and therefore when the rear train arrives at a turnout area, the turnout is switched to the corresponding state.
In implementation, if the operation direction of the front and rear trains in the virtual marshalling train is not consistent with the received turnout state, the step of controlling the front and rear trains to perform the decompiling in the corresponding decompiling area according to the matching relationship between the operation direction of the front and rear trains and the turnout state and the actual rotation time of the turnout comprises the following steps:
if the operation direction of a front vehicle in the virtual marshalling train is inconsistent with the received turnout state and the operation direction of a rear vehicle is consistent with the received turnout state, calculating a third minimum decommissioning distance between the front vehicle and the rear vehicle and the turnout region according to the operation speed of the front vehicle and the received actual rotation time of the turnout;
and controlling the front and rear vehicles to perform the decoding in a third decoding area corresponding to the third minimum decoding distance.
In implementation, if the operation direction of the front and rear trains in the virtual marshalling train is not consistent with the received switch state, the step of controlling the front and rear trains to perform the decompiling in the corresponding decompiling area according to the matching relationship between the operation direction of the front and rear trains and the switch state and the actual rotation time of the switch further includes:
if the operation direction of a front vehicle in the virtual marshalling train is inconsistent with the received turnout state and the operation direction of a rear vehicle is consistent with the received turnout state, determining that the turnout action frequency is 2, and respectively sending turnout action requests to corresponding object controllers by the front vehicle and the rear vehicle so that the object controllers control the turnout to switch the turnout state, and controlling the turnout to switch the turnout state again after determining that the turnout is cleared at the tail of the front vehicle.
In specific implementation, fig. 6 is a schematic diagram of the front and rear cars of the marshalling train requiring turnout actions after being disassembled, if the turnout state is in a positioning state, the front car operates in a reverse direction of the turnout, and the rear car operates in a positioning direction of the turnout; or, if the turnout state is in the reverse position state, the front vehicle runs according to the turnout positioning direction, and the rear vehicle needs to run according to the reverse position direction of the turnout, it is determined that the front vehicle and the rear vehicle need to act on the turnout through the turnout area, namely the turnout action frequency is 2.
Specifically, as shown in fig. 6(1) - (2), assuming that the switch state is in the locating state, if the front car needs to operate in the switch reverse direction, according to the judgment result that the operation direction of the front car in the obtained virtual marshalling train is not consistent with the received switch state and the operation direction of the rear car is consistent with the received switch state, after the front car is determined to send a switch action request to the object controller OC, the front car sends a switch action request to the object controller OC according to the received switch actual rotation time T from the switch health monitoring server, so that the object controller OC can control the switch action to the reverse direction according to the switch action times (the switch action times is 2) included in the switch action request, thereby ensuring that the front car can pass through the switch area in time in the switch reverse direction when reaching the switch area.
Further, as shown in fig. 6(3) - (4), when the object controller OC determines that the preceding vehicle has traveled and passed through the switch area, the switch operation is controlled for the second time to the positioning direction so that the following vehicle passes through the switch area in the switch positioning direction. And the third minimum decoding distance of the grouped train from the turnout area is V x T, the grouped train is decoded in a third decoding area corresponding to the third minimum decoding distance, the third minimum decoding distance is the same as the first minimum decoding distance, and the third decoding area is the same as the first decoding area. Therefore, after the marshalling train is subjected to the decompiling in the third decompiling area, the front train runs at a constant speed, and the rear train runs at a reduced speed, so that the turnout can timely complete corresponding turnout state switching actions when the front and rear train heads respectively reach the turnout area.
In implementation, if the operation direction of the front and rear trains in the virtual marshalling train is not consistent with the received turnout state, the step of controlling the front and rear trains to perform the decompiling in the corresponding decompiling area according to the matching relationship between the operation direction of the front and rear trains and the turnout state and the actual rotation time of the turnout comprises the following steps:
according to the communication delay of the turnout actual rotation time sent by the turnout health monitoring server, the turnout actual rotation time is determined again;
determining a fourth minimum solution distance between the front and rear vehicles and the turnout area according to the redetermined actual turning time of the turnout and the preset safety allowance;
and controlling the front and rear vehicles to perform the decoding in a fourth decoding area corresponding to the fourth minimum decoding distance.
In the concrete implementation, table 1 is a corresponding relation table of turnout states and train running directions, turnout action times and minimum decoding distance of a marshalling train, as shown in table 1, the corresponding relation of the turnout states and train running directions, the turnout action times and the minimum decoding distance of the marshalling train is established, and as the actual rotation time T of the turnout is the important time for determining the minimum decoding distanceInfluence factors, so that in a practical application scenario, the communication delay T is considered for more accurate minimum solution distancedelayAnd a safety margin LsafeTwo important influencing factors. Fig. 7 is a schematic diagram of a relationship between actual turning time of a turnout and minimum decoding distance for decoding a train set in the embodiment of the present application, and as shown in fig. 7, the maximum speed at which a line can run is set to be V, and the actual decoding distance S is set to be V (T + T)delay)+LsafeAs a fourth minimum de-coding distance. The minimum decoding distance difference of the marshalling train, such as the default turnout rotation time of 13 seconds and the healthy turnout rotation time of 7 seconds in the signal system, can be known, the minimum decoding distance of the virtual marshalling train is mainly determined by the actual turnout rotation time, the shorter the actual turnout rotation time is, the shorter the corresponding minimum decoding distance is, therefore, the minimum decoding distance determined based on the actual turnout rotation time T and the application time of the turnout action request can effectively ensure that the front and rear trains pass through the turnout area in time, and further the operation efficiency of the whole line is improved.
TABLE 1 Turnout current state and running direction, and the corresponding relation table of the number of times of turning turnout and the grouping/editing distance
Therefore, the turnout health monitoring server sends the actual turnout rotation time corresponding to different turnout health states to the train, so that the train can calculate the minimum distance of disassembly according to the actual turnout rotation time, the occupation time of trackside resources is reduced, and the train operation efficiency is improved.
The present application takes a specific scenario as an example, and details a first embodiment of the present application are described.
In the actual operation of the marshalling train, when the marshalling train is removed, the front train and the rear train are in a cooperative state, when the operation paths of the front train and the rear train are different, the marshalling train needs to be removed from the marshalling in front of the turnout area according to different operation paths of the front train and the rear train, and the application time and the minimum distance of the determined turnout action request are different according to different turnout health states and different operation paths. Based on this, fig. 8 is a schematic view of an actual application flow of the dynamic compilation method based on virtual marshalling in the embodiment of the present application, and as shown in fig. 8, the dynamic compilation method for a virtual marshalling train includes:
801. the turnout health monitoring server establishes a turnout health detection model in advance.
802. And the turnout health detection devices and the industrial cameras are arranged on two sides of the turnout and respectively transmit the current data of the turnout machine and the shot image information to the turnout health monitoring server in real time.
803. The turnout health monitoring server determines the turnout health state of the current turnout by using the turnout health detection model, and further determines the actual turning time of the turnout in the required direction. Specifically, if the health state of the current turnout is determined to be healthy, the actual turnout rotation time is determined to be 7 seconds, and if the health state of the current turnout is determined to be sub-healthy or unhealthy, the actual turnout rotation time is determined to be 13 seconds, wherein the determination mode of the actual turnout rotation time is not specifically limited.
804. And the turnout health detection server sends the determined actual turnout rotation time to the marshalling train.
805. And the marshalling train calculates the minimum distance required by the marshalling train according to the actual rotation time of the turnout, and then the minimum distance is calculated at the corresponding position.
In addition, the marshalling train receives the current turnout state from the object controller OC, determines the train needing to send the turnout action request and the turnout action times according to the running path in the front and rear train running plan and the matching relation of the received current turnout state, further generates the turnout action request containing the turnout action times by the determined train, and sends the turnout action request containing the turnout action times to the object controller OC according to the actual turning time of the turnout, thereby ensuring that the front and rear trains smoothly pass through the turnout area.
Therefore, different turnout health states are defined, the application time for sending turnout action requests by trains in the marshalling train is adjusted according to the actual turning time of the turnout, and then the disassembly and assembly position corresponding to the turnout action times and the minimum disassembly and assembly distance is determined according to the running path and the turnout state after the marshalling train is disassembled and assembled, so that line resources can be effectively prevented from being occupied when the virtual marshalling train is disassembled and assembled, and the operation efficiency and the safety of lines are improved.
Based on the same application concept, the embodiment of the present application further provides a dynamic compiling and solving device based on virtual grouping, and because the principle of solving the problems of these devices is similar to that of a dynamic compiling and solving method based on virtual grouping, the implementation of these devices can refer to the implementation of the method, and repeated parts are not described again.
