With the continuous development of train signal control, safe and efficient running of trains is increasingly important. With the rapid development of urban rail transit, higher requirements are put forward on the safety and automation of the whole train control system while the urban rail transit is operated efficiently. At present, automation and intellectualization in the field of train control in China are low, and particularly when an overline overlapping area responds to an access person request, the current overline overlapping area access person request processing scheme is as follows: when the access is in a close locking state, the interlocking equipment (CI) can unlock through a total person solution command, and after the total person solution is received, the access state meeting unlocking conditions is converted into a close delay unlocking state. If the delay unlocking time is up, the state of the access is converted from the approach delay unlocking state to the automatic unlocking state.
The determination process of the delay unlocking time length in the process is as follows: and determining the section running time of the train in the train section according to the average travelling speed required by the average travelling speed in the subway safety contract, and further determining the delay unlocking time according to the section running time.
However, the actual average travel speed in actual running is higher than the average travel speed in the contract, so that the delay unlocking time calculated based on the average travel speed in the contract is longer than the actual requirement, the waiting time of the train before the red light signal is greatly increased, and the operation efficiency of the subway line is low.
In order to solve the above problems, the embodiment of the application provides a method for controlling an unlocking route based on a delayed unlocking time, wherein an execution main body of the method is electronic equipment, the delayed unlocking time determined by the application is close to the actual demand, the waiting time of a train in front of a red light signal machine is reduced, and the operation efficiency of subway lines is improved. The specific implementation steps are shown in fig. 1, including:
The simulation result at least comprises the running time of the train at each position of the subway line. The line attribute information includes position information of an active beacon, position information of a station, length information of a line, position information of the line, and the like. The vehicle attribute information includes operation information of the vehicle, equipment information, and the like. The signal equipment provides various equipment for train running, including signal lamp, interlocking equipment and other equipment.
The simulation tool commonly used in subway projects is an X-drive simulation tool, and after a mathematical model is established according to the line attribute information of a subway line, the vehicle attribute information of an operation vehicle and the arrangement information of signal equipment, the model can be input into the simulation tool, and then simulation calculation is carried out by using the tool, so that a simulation result is obtained. The vehicle control algorithm used by the X-drive simulation tool is consistent with the vehicle control method actually used by the signal system, and meanwhile, the established line model and the established vehicle model are consistent with the actual vehicle control method, so that the result of the simulation tool has high consistency with the vehicle control effect during actual automatic driving of the train, and the simulation result can reflect the time and distance relation of normal running of the train.
In the step, the principle of an X-drive simulation tool is specifically introduced: (1) the system is based on energy control: in any case, the system calculates the energy of the train, the braking capacity and the triggering point of braking, and the system is controlled according to the braking curve at the moment; the speed profile is defined in terms of stopping points and ensures that it is within the emergency braking capability (i.e., below the EB touch profile). (2) During braking, the system dynamically controls the train according to the parking spot in front of the train, the state of the trackside equipment and the interference condition. (3) During traction, the system will bring the train to the highest speed allowed as soon as possible. (4) The negative grade (downhill) accelerates the train, the positive grade (uphill) decelerates the train, the gradient effect translates to acceleration, and the simulation calculation will also take into account the train moment of inertia and the train load.
And 102, determining at least one train interval according to the active beacons arranged on the subway line.
Wherein the active beacon is an active transponder. In practice, a transponder antenna is arranged on the train, and when the transponder antenna comes into the signal radiation range of an active transponder, the active transponder is activated, and the data stored by the transponder is transmitted to the transponder antenna. The data generally includes data required by the train during traveling.
In this step, according to the active beacons set on the subway line, the specific process of obtaining the positions of all the active beacons on the subway line is as follows: acquiring the positions of all active beacons on the subway line according to the active beacons arranged on the subway line; determining an active beacon arranged at a station exit of each station as a target active beacon; for any adjacent stations, judging whether a plurality of other active beacons exist between the target active beacons corresponding to the stations respectively; if not, determining the interval between the two target active beacons as a train interval; and if so, determining a train interval according to the target active beacon and the other active beacons.
And setting an active beacon at each station exit, and determining the active beacon as a target active beacon.
In the implementation, according to the active beacons arranged on the subway line, the positions of all the active beacons on the subway line are obtained; and determining the active beacon positioned at the station exit as a target active beacon. In a subway line, all adjacent stations are determined, and for any adjacent station, whether a plurality of other active beacons exist between the target active beacons respectively corresponding to the adjacent stations is judged. If not, it is stated that there is no or only one other active beacon between the two target active beacons. When no other active beacons exist between the target active beacons, data is sent to the train by virtue of the fact that no active beacon exists in the middle, so that if the time required by the train to travel from the previous target active beacon to the next target active beacon is equal to the time delay unlocking time, the train can directly travel through the next target active beacon without waiting at the position of the train to travel to the next target active beacon. Therefore, the length of time required for the train to travel from the last target active beacon to the next target active beacon can be determined, and the interval between the two target active beacons needs to be determined, so the interval between the two target active beacons is determined as the train interval. When one active beacon exists between the target active beacons, the distance between the two target active beacons determines the effective time of data sent to the train by the active beacons according to regulations, and therefore the interval between the two target active beacons is determined as the train interval.
The data transmitted from the active beacon to the train is substantially variable data used by the train in the backup mode, and is used as a backup mode variable. When the backup mode variable fails, the train can perform emergency braking, and then the train stops. In order that the train does not stop in the event of passing the target active beacons, the effective time of the train carrying the backup mode variable is related to the train interval formed between two target active beacons when there is no or only one other active beacon between the two target active beacons.
If a plurality of active beacons exist between the two target active beacons, determining a train interval according to the target active beacons and the other active beacons, wherein the specific steps are as follows: determining two active beacons spaced one active beacon apart from the target active beacon and other active beacons; the interval between two active beacons is determined as the train interval.
In an implementation, among active beacons composed of a target active beacon and other active beacons, two active beacons that are spaced apart by only one active beacon in the middle are determined, that is, active beacons adjacent to the two active beacons are the same active beacon. The interval between the two active beacons is determined as the train interval.
In order to prevent the train from stopping when passing through the last active beacon of the two active beacons, the active time of the backup mode variable is related to a train section formed between any two active beacons spaced apart by one active beacon when there are a plurality of other active beacons between the two target active beacons.
For example, as shown in fig. 2, the triangle in fig. 2 represents an active beacon, and thus, there are 4 active beacons in fig. 2, active beacon 1, active beacon 2, active beacon 3, and active beacon 4, respectively. The active beacon 1 is a target active beacon corresponding to the station 1, and the active beacon 4 is a target active beacon corresponding to the station 2. Since the active beacon 2 and the active beacon 3 exist between the active beacon 1 and the active beacon 4, the section between the active beacon 1 and the active beacon 2 cannot be determined as a train section, but two active beacons of one active beacon at each interval are determined, and the section between the two active beacons is determined as a train section, for example, the section between the active beacon 1 and the active beacon 3 is determined as a train section, and the section between the active beacon 2 and the active beacon 4 is determined as a train section.
The interval running time is the time for simulating the running of the actual train in the corresponding train interval, and the time is close to or even the same as the running time of the train in the corresponding train interval.
In a specific embodiment of the step, according to at least one train section, in a simulation result, the section operation duration of the train in the at least one train section is determined, and at least one section operation duration is obtained. The method comprises the following specific steps: for each train interval, judging whether an end active beacon of the train interval is a target active beacon; if so, acquiring a starting position, a train stopping position and a terminating position in the train section, and determining the section running time of the train in the train section according to the starting position, the train stopping position and the terminating position; if not, acquiring the starting position and the ending position in the train section, and determining the section running time of the train in the train section according to the starting position and the ending position.
Wherein the train travels from a start active beacon to an end active beacon of the train. The position corresponding to the initial active beacon is the initial position, and the position corresponding to the termination active beacon is the termination position. The stop position is a position where the train stops in the station. When the end active beacon is the target active beacon, the train passes through the station, and the train stops when passing through the station, so the interval running time length comprises the time length of the train stopping at the station. When the end active beacon is not the target active beacon, the train is not passed through the station, and the interval running duration does not comprise the duration of stopping the train at the station.
Further, according to the starting position, the train stopping position and the ending position, determining the section running duration of the train in the train section, specifically comprising the following steps: acquiring a starting time point of the train at the starting position, a stopping time point and a starting time point at the stopping position of the train and a terminating time point at the terminating position respectively according to the starting position, the stopping position and the terminating position of the train; determining a first duration according to the starting time point and the stopping time point, determining a second duration according to the stopping time point and the starting time point, and determining a third duration according to the starting time point and the ending time point; and adding the first time length, the second time length and the third time length to obtain the interval operation time length.
The time point of the train at the starting position is determined as a starting time point, the time point of the train at the ending position is determined as an ending time point, the time point of the train just stopped at the stopping position is determined as a stopping time point, and the time point of the train just started at the stopping position is determined as a starting time point.
In the implementation, according to the starting position, the train stopping position and the ending position, respectively acquiring a starting time point of the train at the starting position, a stopping time point and a starting time point at the train stopping position and an ending time point at the ending position; determining a difference value between a starting time point and a stopping time point as a first duration of the train running to the stopping position, determining a difference value between the stopping time point and a starting time point as a second duration of the train stopping at the stopping position, and determining a difference value between the starting time point and the stopping time point as a third duration of the train running from the stopping position to the ending position; and adding the first time length, the second time length and the third time length to obtain the interval operation time length.
Further, determining the section operation duration of the train in the train section according to the starting position and the ending position specifically includes: acquiring a starting time point of the train at the starting position and a terminating time point of the train at the terminating position respectively according to the starting position and the terminating position; and determining the difference between the starting time point and the ending time point as the interval running time of the train in the train interval.
For example, as shown in fig. 2, when the section between the active beacon 1 and the active beacon 3 is determined as a train section, since the control center informs the state of the active beacon 2 of the train in advance, the train may not stop at the active beacon 2 but directly pass through the active beacon 2, and thus the section operation duration corresponding to the train section is the duration in which the train travels from the active beacon 1 to the active beacon 2 in the simulation result.
When the section between the active beacon 2 and the active beacon 4 is determined as a train section, since the train mission requires the train to stop in the station, the section operation time corresponding to the train section includes three parts, namely, the time from the active beacon 2 to the stop position, the stop time of the train at the stop position, and the time from the stop position to the active beacon 4. The sum of these three durations is thus determined as the section run duration of the train section.
And 104, determining a delay unlocking time length according to at least one interval operation time length, so that after the control center receives the total manual unlocking command, the interlocking equipment is controlled to perform an unlocking route after the delay unlocking time length.
In the implementation, whether the interval operation time is multiple or not is judged, and if not, the only interval operation time is determined to be the delay unlocking time. If so, comparing the plurality of interval operation time lengths, selecting the interval operation time length with the longest time length from the plurality of interval operation time lengths, and determining the interval operation time length as the delay unlocking time length, so that after the control center receives the total manual unlocking command, the control interlocking equipment performs an unlocking route after delaying the unlocking time length.
For example, as shown in fig. 2, since the communication terminal of the train and the control center is in the backup mode, when the train runs to the active beacon 1 in the backup mode, the active beacon 1 forwards the signal lamp related data transmitted by the control center to the train. For example, the traffic light-related data includes that the traffic light corresponding to the active beacon 3 is green after delaying the unlocking period. Thus, if the time length of the train from the active beacon 1 to the active beacon 3 is exactly equal to the delay unlocking time length, the signal lamp at the active beacon 3 is exactly green, and the corresponding approach is exactly unlocked, so that the train does not need to stop when running to the active beacon 3. If the duration of the train running from the active beacon 1 to the active beacon 3 is not equal to the delay unlocking duration, waiting is required when the train runs to the active beacon 3.
It should be noted that if the delay unlocking duration is set to be too small, the train is not driven to the route, and the route is unlocked earlier according to the driving route of the train, so that the driving of other trains on the route is affected, and the operation efficiency of the train line is further affected. If the delay unlocking time is set to be too large, the waiting time process of the train in the approach is caused, and the operation efficiency of the train line is also affected. The time delay unlocking time length of the method is close to the time length actually needed, the method is neither too large nor too small, and the operation efficiency of a train line is improved.
In the embodiment of the application, in a simulation tool, a simulation result is obtained according to line attribute information of a subway line, vehicle attribute information of an operation vehicle and arrangement information of signal equipment; determining at least one train interval according to the active beacons arranged on the subway line; in the simulation result, determining the interval running duration of the train in at least one train interval according to the at least one train interval; and determining a delay unlocking time length according to the at least one interval operation time length, so that after the control center receives the total personnel unlocking command, the interlocking equipment is controlled to perform an unlocking route after the delay unlocking time length. The delay unlocking time length determined by the method is close to the actual demand, the waiting time of the train before the red light signal is reduced, and the subway line operation efficiency is improved.
Further, as an implementation of the method embodiment shown in fig. 1-2, the embodiment of the application provides a device for controlling an unlocking route based on a delayed unlocking time, and the delayed unlocking time determined by the device is close to the actual demand, so that waiting time of a train in front of a red light signal is reduced, and subway line operation efficiency is improved.
