Description
Technical Field
The present invention relates to the field of vehicle door docking, and more particularly, to a vehicle door docking method and a computer storage medium for a movable platform door.
Background
With the gradual increase of the degree of urbanization in China, the demand for rail transit is continuously increased. The rail transit platform door can effectively isolate a rail area from a platform area, so that active/passive accidents (such as casualty accidents caused by personnel falling off the platform or impacting a running train) of passengers in the platform area during waiting are prevented. The part of a rail transit platform door adopted by each station on the ground at present comprises a sliding door capable of being opened and closed movably, a fixed door incapable of being moved and the like, the sliding door and a vehicle door are opened simultaneously after a train arrives at the station so as to be convenient for passengers to get on or off the train, and the fixed door is fixed in place all the time. However, the number of high-speed rail/intercity train types in China is more than 7, and the platform door is required to be capable of realizing self-adaptive functions of different train types and different door opening positions. On this basis, a movable platform door is proposed, which comprises a plurality of sliding doors for docking with the doors of the train. The entire movable platform door can be moved to the appropriate position along the track/rail at the platform, and each sliding door itself may also be moved along the track/rail at the platform. Therefore, the movable platform door and/or each sliding door can be moved independently to be in butt joint with the vehicle door, so that the requirements of different types of high-speed rail/urban rail trains on different door opening positions are met.
However, when the movable platform door works, if the sliding door closest to the current high-speed rail/inter-city train arrival door is simply arranged to be in butt joint every time a train arrives at a station or a certain sliding door is established for each train to be in butt joint every time, the moving scheme of the platform door within the set time may not be optimal, and the total moving distance may be longer when the platform door moves integrally and when the sliding doors adjust the mutual distance, so that the device loss and the energy consumption are larger, and the movable platform door is not favorable for reducing the operation cost and low-carbon environmental protection.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention relates to a vehicle door butt joint method of a movable platform door, which comprises the steps of obtaining all vehicle door positions of all arriving trains within set time according to train scheduling information and sequencing according to time; circularly simulating a vehicle door and sliding door butt joint scheme according to the priority of the arrival time and based on the vehicle door butt joint ratio in the set range for each train arriving at the station within the set time, and respectively calculating the sum of the moving distances of the whole movable platform door and each sliding door of the movable platform door in each butt joint scheme; the vehicle door butt joint ratio is the ratio of the number of idle sliding doors which can be correctly butted with the vehicle door to the total number of the vehicle doors; and selecting a docking scheme with the sum of the distances as the minimum value as the vehicle door docking scheme in the set time.
The invention selects the scheme with the shortest adjusting moving distance (including the integral moving distance of the platform door and the moving distance of the adjusting mutual distance of the sliding door) of the movable platform door within the set time from a plurality of schemes of the vehicle doors which arrive at the station according to the time sequence of the butt joint set time of the sliding door of the movable platform door by simulating and adjusting the butt joint ratio of the vehicle doors, and takes the scheme as the butt joint scheme of the vehicle doors and the sliding doors with the final set time, thereby shortening the running distance of the platform door within the set time, reducing the total running time of the adjusting position within the set time of the platform door, reducing the abrasion of parts during the running of equipment, reducing the maintenance times, energy consumption and cost, meeting the low-carbon and environment-friendly requirements, further avoiding the longer moving distance of the movable platform door when the sliding door of the platform door is butt joint the vehicle door according to the nearest or the appointed principle, causing larger device loss and energy consumption, the operation cost is not reduced, and the defects of low carbon and environmental protection are overcome.
Fig. 1 is a flowchart of a preferred embodiment of a method for docking a door of a movable platform door according to the present invention. As shown in fig. 1, in step S1, all the door positions of all the trains arriving at the station within the set time are acquired according to the train schedule information and sorted by time. Here, a certain time point in a day can be selected as a starting time T, arrival time, vehicle type and marshalling information of all trains which are to arrive at the station on the day are obtained according to train scheduling information of the station, and positions of all doors arranged on the day in time sequence can be calculated. Of course, subsequent sequencing and simulation may also be performed at other time periods, such as half a day, four hours, and so on.
In step S2, circularly simulating a door and sliding door docking scheme based on a door docking ratio of a set range according to the priority of the arrival time for each train arriving at the station within the set time, and calculating the sum of the moving distances of the entire movable platform door and each sliding door of the movable platform doors in each docking scheme; the vehicle door butt joint ratio is the ratio of the number of idle sliding doors which can be correctly butted with the vehicle door to the total number of the vehicle doors.
The invention is suitable for the situation that the density of the sliding doors of the movable platform doors is greater than that of the train doors of the arriving train, namely, the number of the sliding doors of the movable platform doors exceeds that of the train doors under the condition of the same length. And each platform only has one train to arrive at the station in the same time period, and the arrival position of each train is set according to a fixed rule, for example, the head of each train is at the same position, or the central point of each train is at a fixed position. Thus, all trains are within a fixed segment area. It may be necessary to move the movable platform door as a whole or the sliding door of the movable platform door separately only because there is a difference in the length and number of the cars of the train. The object of the invention is to shorten the total distance of movement of the platform doors and the sliding doors of the platform doors.
In the preferred embodiment of this step, we obtain the distance that the movable platform door needs to be adjusted to move in multiple schemes that the movable platform door is docked to the platform door in chronological order on the day by simulating and adjusting the docking ratio of the vehicle door to the movable platform door sliding door when the train stops.
Fig. 4 is a schematic view of the docking of a vehicle door and a sliding door using the vehicle door docking method of the mobile platform door of the present invention. As shown in fig. 4, doors 11 are provided at both ends of each car of the train 10. The movable platform door 20 is provided with a plurality of sliding doors 21, and under the condition of the same length, the number of the sliding doors 21 of the movable platform door exceeds the number of the vehicle doors 11.
In a preferred embodiment of the invention, the vehicle door butt-joint ratio is a ratio of the number of idle sliding doors which can be correctly butted with the vehicle door to the total number of the vehicle doors. For example, there are 16 sliding doors such as a movable platform door, 12 doors for the first incoming train, and 8 doors for the second incoming train. Then for the train at the first arrival, the number of the idle sliding doors is 16, so that 12 vehicle doors can be correctly butted with the idle sliding doors, and the number of the idle sliding doors which can be correctly butted with the vehicle doors is 16. For the second train, since 12 sliding doors are already occupied by the first train, 4 sliding doors are left, and therefore, the number of free sliding doors capable of being correctly abutted with the train doors is 4, and the train door abutting ratio is 4/8= 0.5. If the number of sliding doors of the movable platform door is large enough, the whole train butt joint scheme can be adopted for each train, but the scheme is not practical and the cost is high. Therefore, in general, the density of the sliding doors of the movable platform door is greater than that of the doors of the arriving train, and the number of the sliding doors is 1.2 to 2 times of the maximum number of the doors in the arriving train. Of course, the number of the sliding doors can be set according to actual conditions.
Fig. 2 is a flowchart illustrating a preferred simulated docking process of the method for docking a door of a movable platform door according to the present invention shown in fig. 1.
As shown in fig. 2, in step S21, a maximum door butt ratio α 2, an initial door butt ratio α 1, and a set butt ratio interval β are set, and β ≦ α 2- α 1, and a current door butt ratio α = the initial door butt ratio α 1 is set. The butt joint ratio of the vehicle doors is the butt joint number of the vehicle doors and the sliding doors/the total number of the trains. Because the whole simulation docking process is a simulation process with the docking ratio increasing continuously, the maximum vehicle door docking ratio alpha 2, the initial vehicle door docking ratio alpha 1 and the set docking ratio interval beta can be selected according to actual needs. In general, the larger the interval between the initial door butt ratio α 1 and the maximum door butt ratio α 2 is, the smaller the set butt ratio interval β is, the larger the number of simulations is, the longer the calculation time is, and the larger the candidate distance is, the better the result can be obtained. However, since a larger maximum door butt ratio α 2 means a larger number of moving doors to be prepared, it is generally preferable to select a single folding value, and it is preferable to set the initial door butt ratio α 1 to 60%, the maximum door butt ratio α 2 to 80%, and the set butt ratio interval β to 2-10%. Of course, the specific values can be changed according to actual needs.
In step S22, it is determined whether the door-to-door ratio of the coming train is equal to or less than the current door-to-door ratio α, and if so, step S23 is executed, otherwise, step S24 is executed. As mentioned above, the door-to-door ratio of the arriving train is the ratio of the number of idle sliding doors and the number of doors that can be properly docked with the train doors. As in the previous example, the train coming to the station in the second time is taken as the train coming to the station, the number of the doors is 8, 12 sliding doors are already occupied by the train in the first time, so 4 sliding doors are left, and therefore, the number of the idle sliding doors capable of being correctly butted with the doors is 4, so that the door butting ratio is 4/8= 0.5. If the current door-to-door ratio α = the initial door-to-door ratio α 1 (0.6) at this time, the door-to-door ratio 0.5 of the oncoming train is smaller than the current door-to-door ratio 0.6, and then step S23 is executed to perform the entire door-to-door docking of the doors of the oncoming train and the movable platform doors according to the arrival time priority. And returning to the step S22, continuing to judge the next train until all inbound trains within the set time are traversed, and then executing the step S26 to calculate the sum of the moving distances of the whole movable platform door and each sliding door of the movable platform door within the set time under the current door butt-joint ratio alpha. If the door-to-door ratio of the coming train is greater than the current door-to-door ratio α, then we proceed directly to step S24. In step S24, it is determined whether the current door butt ratio α is larger than the maximum door butt ratio α 2. If the current door butt ratio α is found to be greater than the maximum door butt ratio α 2, which indicates that the whole simulation process can be ended, we can execute step S3 to select the butt-joint scheme with the minimum sum of the distances as the door butt-joint scheme within the set time. That is, the sum of the distances moved by the entire movable platform door and each sliding door of the movable platform doors within the set time at the calculated current door-to-door ratio α obtained in step S26. If the current door butt-joint ratio alpha is smaller than or equal to the maximum door butt-joint ratio alpha 2, the current door butt-joint ratio alpha = alpha + beta, then the loop simulation is carried out by returning to the step S22 until the current door butt-joint ratio alpha is larger than the maximum door butt-joint ratio alpha 2, and the simulation process is finished. Of course, the foregoing steps S1-S3 may be repeatedly executed according to the actual arrival time of the train and the scheduling scheme, so as to continuously update, and further obtain the subsequent door docking scheme.
In a further preferred embodiment of the invention, the integral door docking of the doors of the inbound train and the movable platform doors according to the arrival time priority preferably employs the proximity and free principle. For example, for the first arriving train within a set time, no sliding door is occupied at the moment, so that the movable platform door is directly and integrally moved to be butted with the train door. The movable platform door can be integrally moved to be aligned with the head of the train or the parking space, and then the butt joint adjustment of the idle train door and the adjacent sliding door is carried out. Of course, in other preferred embodiments, since the initial state of the movable platform door is located at the stopping point facing the train head, the whole platform door does not need to be moved, and the alignment operation can be directly performed.
Specifically, it may be determined whether two adjacent sliding doors of the train door are idle, and if yes, the sliding door closest to the train door is selected for docking, otherwise, it is determined whether one of the two adjacent sliding doors of the train door is idle, and if yes, the idle sliding door is selected for docking. If neither of the two adjacent sliding doors of the vacant door are vacant, then a partial door butt adjustment option needs to be selected.
Fig. 3 is a flowchart of a partial vehicle door docking adjustment scheme of the vehicle door docking method for the movable platform door of the present invention shown in fig. 2. As shown in fig. 3, in step S2331, a vacant door and an adjacent door whose distance is smaller than d are divided into a door set a by taking the average distance d of the doors as a standard, where n doors are in the set a and n is a positive integer. According to the distribution characteristics of the train doors at present, n is generally less than or equal to 3.
In step S2332, the set of the sliding doors of the movable platform door that have been butted against the vehicle doors in the set a and the idle sliding doors is divided into a sliding door set B, where m sliding doors are in the set B, and m is a positive integer.
In step S2333, a determination is made as to whether m is less than n, and if so, this indicates that the local door docking adjustment has failed to solve the alignment problem and requires the entire movement of the movable platform door, and then the process returns to step S23 to perform the entire movement again.
If m is greater than or equal to n, then go to step S2334; and selecting n sliding doors from the set B to be matched with n vehicle doors in the set A, wherein C (m, n) matching schemes can be obtained. It is of course possible that in some movable platform doors, their sliding doors may have a limited sliding distance. At this time, assuming that h matching schemes that cannot be achieved are removed according to the sliding distance limit of the sliding door, C (m, n) -h matching schemes are obtained for the subsequent step S2335. Of course, in other preferred embodiments of the present invention, other limitations may be set, or no limitations may be made at all.
In step S2335, a plan in which the sum of the moving distances of the sliding doors is the shortest among the matching plans is acquired as a partial vehicle door butting adjustment plan.
By implementing the vehicle door butt joint method of the movable platform door and the computer storage medium, the running distance of the movable platform door in the set time can be shortened, and the total running time of the position adjustment of the movable platform door in the set time is reduced, so that the abrasion of parts during the running of equipment is reduced, the maintenance times, the energy consumption and the cost are reduced, and the low-carbon environmental protection requirements are met. Further, the present invention can obtain a more preferable shortest moving distance scheme by combining the global movement adjustment and the local movement adjustment.
In a further preferred embodiment of the present invention, the vehicle door docking method of the movable platform door may be performed as follows.
Assuming that the butt-joint ratio of the vehicle door and the sliding door is alpha (alpha = the butt-joint number of the sliding doors of the vehicle door and the platform door/the total number of the train doors of the arriving train is alpha 1 is larger than or equal to alpha 2), the butt-joint ratio interval beta (beta is larger than or equal to alpha 2-alpha 1) is set during each adjustment, and the specific flow is described as follows:
(1) let α = α 1.
(2) Setting the current time as the starting time T, and preparing for butt joint simulation.
(3) And carrying out overall vehicle door butt joint adjustment, wherein the sliding door of the movable platform door is in butt joint with the vehicle door position of the train which will arrive at the station at the subsequent moment, the vehicle door butt joint priority of the train which arrives at the station at the previous moment is higher, and generally, the vehicle doors of a plurality of subsequent trains which arrive at the station are in butt joint in advance according to the arrival time sequence. Specifically, the step may include butting the idle vehicle doors according to the principle of proximity and idleness, that is, if two adjacent sliding doors of the idle vehicle doors are both idle, butting according to the principle of proximity; if only 1 adjacent sliding door is idle, arranging the idle sliding door to be in butt joint with the idle sliding door; if the adjacent 2 sliding doors are not idle, the local vehicle door butt joint adjusting method is adopted for butt joint, and if the local vehicle door butt joint adjusting method cannot realize the butt joint of all the vehicle doors, the whole vehicle door butt joint adjustment is switched back.
(4) And (4) when the butt joint ratio of the train doors of the train coming to the station is less than or equal to alpha%, turning to the step (3) to perform integral butt joint adjustment of the train doors until the butt joint of all the train doors in the same day is completed.
(5) Calculating the total moving distance of the movable platform door (without opening and closing of the sliding door) under the current ratio alpha, namely the sum D of the moving distances of the platform door moving integrally and the movable door adjusting mutual distanceαAnd stored in memory.
(6) When alpha is less than or equal to alpha 2, let alpha = alpha + beta, go to step (2), and when alpha is less than or equal to alpha 2>When alpha 2 is reached, stopping the circulation simulation, and obtaining the minimum value D of the total moving distance of the movable platform door in each scheme in the memory by comparisonmThe butt joint strategy of the corresponding platform sliding door and the train door is the result.
In the preferred embodiment, the local door interface adjustment method is as previously described and will not be described again.
By implementing the vehicle door butt joint method of the movable platform door and the computer storage medium, the running distance of the movable platform door in the set time can be shortened, and the total running time of the position adjustment of the movable platform door in the set time is reduced, so that the abrasion of parts during the running of equipment is reduced, the maintenance times, the energy consumption and the cost are reduced, and the low-carbon environmental protection requirements are met. Further, the present invention can obtain a more preferable shortest moving distance scheme by combining the global movement adjustment and the local movement adjustment.
