Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to facilitate a clearer understanding of the various embodiments of the present application, some relevant background knowledge is first presented below.
In recent years, platform door systems have been popularized and applied in part of inter-city railways and high-speed railways. However, the types of trains operated on the same line are complex and various, and part of old vehicles only adopt automatic train protection (Automatic Train Protection, ATP) control, and the related functions of automatic train operation (Automatic Train Operation, ATO) are not realized, if the automatic train protection is modified, the cost is huge, so that the linkage control with a signal system in urban rail transit is not realized.
In the related art, most stations control a station door switch by manually operating an on-site control panel installed on a station, and for each vehicle type, a corresponding door opening control button is arranged on the on-site control panel, which requires a station operator to identify the currently-in-service train type and accurately execute corresponding operation, and if the button operation is wrong, the station door outside the vehicle marshalling range is opened, which causes a great potential safety hazard.
With the increasing call of passenger departments for automatic control of platform doors, some platform door automatic control technologies, including image recognition technology and millimeter wave radar detection technology, are presented in the industry.
The image recognition technology collects real-time images of a station through a camera and analyzes the vehicle type and parking accuracy of an incoming train, and the mode is easily influenced by external environmental factors such as weather, vibration, light intensity and the like and cannot guarantee stability and reliability.
The millimeter wave radar detection technology judges the entrance and exit of a train by capturing a moving object on a track, so that the platform door is controlled to execute corresponding actions.
Accordingly, in order to solve the above-mentioned problems, the present invention provides a method, apparatus, electronic device, and storage medium for controlling a platform door by automatically and accurately transmitting a door opening/closing command.
The method for controlling a platform door according to the present invention will be described in detail with reference to fig. 1. Fig. 1 is a schematic flow chart of a method for controlling a platform door according to the present invention, referring to fig. 1, the method includes steps 101 to 103, wherein:
Step 101, obtaining scheduling data of a target train; the target train is a train to be inbound, the scheduling data comprises first grouping length and vehicle type information of the target train, and the first grouping length is a preset grouping length of the target train.
Firstly, it should be noted that the execution body of the present invention may be any electronic device with a platform door control function, for example, any one of a smart phone, a smart watch, a desktop computer, a laptop computer, etc., and may be, for example, a dispatch control server installed in a station room.
In order to automatically and accurately send a door opening and closing command to control a platform door system, in the embodiment of the invention, first, scheduling data of a target train needs to be acquired, wherein the target train is a train to be entered (i.e. to be entered), and a first grouping length of the target train is a preset grouping length of the target train in the scheduling data.
In practical application, the execution body can be connected to the national railway group dispatching system through the railway intranet and acquire dispatching data of a target train to be arrived from the national railway group dispatching system in real time.
Specifically, the scheduling data of the target train obtained from the national iron group scheduling system mainly includes:
A. Daily schedule including schedule information of trains including planned arrival time, planned departure time, arrival times, departure times, and stop tracks.
B. Stage planning: the stage planning is a plan of every three hours and is used for correcting the planned arrival time and the planned departure time of the train.
C. Until the actual time: the actual information of the train comprises actual arrival time, actual departure time, actual arrival train number and actual departure number.
D. Schedule: including stop stops, expected residence times.
E. Vehicle bottom planning: and acquiring the vehicle type information through the vehicle bottom plan, and calculating the marshalling length of the train according to the vehicle type information.
102, acquiring a second marshalling length and a parking state of the target train; matching the second group length with the first group length; the second marshalling length is the actual marshalling length of the target train, and the stop state at least comprises the start of entering and stopping and leaving.
In this embodiment, after the schedule data of the target train is obtained, the second grouping length and the stop information of the target train need to be obtained; the second group length is then matched to the first group length.
The second grouping length is the actual grouping length of the target train in the station, and it is required to be noted that whether the data corresponding to the target train in the dispatching system is accurate or not can be verified by matching the second grouping length with the first grouping length;
the target train stop information is used for indicating a running state after the target train enters the station, and the stop information at least comprises: the inbound stops, the outbound starts and the train passes through.
Step 103, determining a target control instruction based on the vehicle type information and the parking state and sending the target control instruction to a platform door controller under the condition that the second grouping length is successfully matched with the first grouping length; the target control instruction is used for controlling the platform door to open or close by the platform door controller.
In this embodiment, the second grouping length is matched with the first grouping length, and in case of successful matching, it is indicated that the actual incoming target train is matched with the scheduling information of the target train in the scheduling system; and determining a target control instruction based on the vehicle type information and the stopping state of the target train, and sending the target control instruction to the platform door controller so that the platform door controller controls the opening or closing of the platform door based on the target control instruction.
According to the platform door control method, the scheduling data of the target train are obtained, wherein the scheduling data comprise first grouping length and vehicle type information of the target train, and the first grouping length is preset grouping length of the target train; then, a second grouping length of the target train and a parking state are obtained, wherein the second grouping length is the actual grouping length of the target train, and the parking state at least comprises stop of entering a station and start of leaving the station; matching the second grouping length with the first grouping length, and under the condition that the second grouping length is successfully matched with the first grouping length, indicating that the actually-arrived train is matched with the scheduling information of the target train; and determining a target control instruction based on the train type information and the parking state, and sending the target control instruction to a platform door controller so that the platform door controller controls the platform door to start or close based on the target control instruction, thereby achieving the aim of automatically controlling the operation of the platform door according to the train type information, improving the station operation efficiency and further promoting the intelligent development process of the platform door system.
Optionally, in a possible implementation manner of the embodiment of the present invention, at least one ranging sensor and a speed measuring sensor are installed at the platform;
The obtaining the second grouping length and the parking state of the target train can be achieved by the following steps of 1) to 4):
step 1), acquiring distance information acquired by each ranging sensor, wherein the distance information is the distance between the ranging sensor and an object shielding the ranging sensor;
step 2), determining the second grouping length based on each distance information;
step 3), acquiring speed change information acquired by each speed measuring sensor, wherein the speed change information reflects the speed change condition of the target train;
and 4) determining the parking state based on the speed change information.
In this embodiment, the distance measuring sensor is mounted on the cross beam of the platform door body, and the distance is collected in a direction facing the track and perpendicular to the track.
For example, 4 platforms are arranged on each side of the platform and are respectively positioned at the positions corresponding to the carriages of the 4 th section, the 5 th section, the 12 th section and the 13 th section. When the target train enters the station, distance information acquired by each ranging sensor may be acquired, and a second consist length may be determined based on the distance information.
The speed measuring sensors are arranged on door body stand columns or cross beams at two ends of the platform, speed change information acquired by each speed measuring sensor is acquired in real time by facing the track, and the stopping state of the target train is determined based on the speed change information.
In the above embodiment, distance information collected by each ranging sensor and speed change information collected by each speed measuring sensor are obtained respectively, and then a second grouping length is determined based on each distance information; determining a parking state based on the speed change information; by the method, whether the scheduling information of the target train actually entering the station is matched with the scheduling information of the target train in the scheduling system or not can be determined by utilizing the second grouping length; under the condition of matching, different control instructions can be determined by utilizing the stop state (namely, stop-in, start-out and stop-out) of the target train, so that the platform door controller controls the opening or closing of the platform door based on the target control instructions, and the aim of automatically controlling the operation of the platform door according to the train model information is achieved.
Optionally, in a possible implementation manner of the embodiment of the present invention, the determining the second grouping length based on each distance information may specifically be implemented by the following steps [1] -step [ 2):
step [1], determining the ranging sensor with the distance information smaller than and/or equal to a preset distance threshold value as a target ranging sensor;
step [2], determining the second group length based on the number of target ranging sensors.
In this embodiment, after the distance information acquired by each ranging sensor is acquired, it is necessary to select a target ranging sensor among a plurality of ranging sensors as a ranging sensor for determining the second group length. That is, a ranging sensor whose distance information is less than and/or equal to a preset distance threshold value is taken as a target ranging sensor that detects a target train.
A second group length is then determined based on the number of target ranging sensors. For example: when a target train stops at a platform, the distance information acquired by a distance measuring sensor (also called a distance measuring module) is a linear distance S from the installation position of the distance measuring module to the target train in the direction vertical to the track, and the S is taken as a preset distance threshold;
when no train stops on the platform, the output data of the ranging module is far greater than S, so that a certain margin S1 is added on the basis of the value S and is used as a judgment basis, and whether the train enters or not can be detected by comparing the output value of the ranging module with the output value in real time.
Since the current train has only 8, 16 and 17 groups, the second group length of the train can be detected by arranging the ranging modules at 1/4 and 3/4 of the transverse position of the platform, and two sets of modules are arranged at each position to ensure the reliability of detection. The effective detection results of the 4 ranging modules at each side are divided into the following 3 cases, and the process of detecting the second grouping length is specifically described with reference to fig. 2 to 4:
1) FIG. 2 is one of the schematic diagrams provided by the present invention for determining a second group length;
in fig. 2, there is one target train (8 consist trains, including cars 1-8); two speed measuring modules (namely speed measuring sensors 1-2) and four distance measuring modules (namely distance measuring sensors 1-4) are arranged at the platform; the modules are connected through a field bus and are connected to a dispatching control module (such as a dispatching control server) in the platform door equipment room; the dispatching control module sends a door opening and closing instruction to the central control panel based on data transmitted by the field bus.
And if the distance measuring modules (namely, the distance measuring sensor 1-2 is taken as a target distance measuring sensor) at the 4 th and 5 th carriages arranged at the platform detect the vehicle body, and other modules do not detect the vehicle body, the target train is determined to be the front 8 marshalling trains, and the second marshalling length is 8.
2) FIG. 3 is a second schematic diagram of determining a second group length according to the present invention;
in fig. 3, there is one target train (8 consist trains, including cars 1-8); two speed measuring modules (namely speed measuring sensors 1-2) and four distance measuring modules (namely distance measuring sensors 1-4) are arranged at the platform; the modules are connected through a field bus and are connected to a dispatching control module (such as a dispatching control server) in the platform door equipment room; the dispatching control module sends a door opening and closing instruction to the central control panel based on data transmitted by the field bus.
And the distance measuring modules (namely, the distance measuring sensors 3-4 are used as target distance measuring sensors) arranged at the 12 th and 13 th carriages of the platform detect the vehicle body, and if the other modules are not detected, the target train is determined to be a rear 8-group train, and the second group length is 8.
3) FIG. 4 is a third schematic illustration of determining a second group length provided by the present invention;
in fig. 4, there is one target train (17 consist trains, including cars 1-17); two speed measuring modules (namely speed measuring sensors 1-2) and four distance measuring modules (namely distance measuring sensors 1-4) are arranged at the platform; the modules are connected through a field bus and are connected to a dispatching control module (such as a dispatching control server) in the platform door equipment room; the dispatching control module sends a door opening and closing instruction to the central control panel based on data transmitted by the field bus.
And 4, if the ranging module (namely, the ranging sensor 1-4 is taken as a target ranging sensor) fully detects the train body, determining that the target train is 16/17 of the grouped trains, and the second grouping length is 16/17.
In the above-described embodiment, the distance sensor whose distance information is smaller than and/or equal to the preset distance threshold value is determined as the target distance sensor; then, based on the number of the target ranging sensors, the second grouping length of the target train can be accurately determined; and determining whether the scheduling information of the target train actually entering the station is matched with the scheduling information of the target train in the scheduling system by utilizing the second grouping length so as to improve the accuracy of generating different control instructions, so that a platform door controller controls the opening or closing of the platform door based on the target control instructions, and the aim of automatically controlling the operation of the platform door according to the train model information is fulfilled.
Optionally, in a possible implementation manner of the embodiment of the present invention, the determining the parking status based on each of the speed change information may be implemented by the following steps a) -c):
step a), determining the running direction of the target train based on the speed change information;
step b), determining a target speed sensor based on the driving direction;
and c) determining the parking state based on the speed change information acquired by the target speed sensor.
In this embodiment, since the directions of arrival of the target trains are different, it is first necessary to determine the target speed sensor as a source of the target train speed change information; after the target speed measuring sensor is determined, the stopping state of the target train can be determined based on the speed change information acquired by the target speed measuring sensor, namely, the stop of the target train after entering the station is determined, or the start of the target train after leaving the station is required.
Compared with the passing train, the speed of the target train for getting on and off passengers gradually decreases in the process of getting on and off, the speed decreases to zero when reaching the stop standard, and after the passengers take the car, the target train starts to start and gradually increases corresponding to the speed.
The target speed sensor can judge the movement of the target train entering the station by capturing the descending process of the target train speed; when the speed of the target train is detected to be zero, a short delay (calculation time and filtering time) is passed, and the target train is judged to be stationary when entering the station. In this case, in order to ensure the accuracy of the result, the distance information of the ranging module needs to be synchronously acquired, and a train inbound stable signal is finally output when the target train is verified to stop.
On the premise that the target train arrival and stop stabilizing signal is effective, the process of capturing the speed rise can be used for judging that the target train starts to leave the station and outputting a corresponding signal. The target train start-up departure signal is therefore always established after the train has started up.
The following describes the process of determining the traveling direction of the target train in detail:
the traveling direction of the target train entering is divided into two cases:
1) To be stepped on from the left when facing the track; 2) And stands by the right side when facing the track.
Therefore, in order to distinguish the arrival direction of the target train, it is necessary to determine the traveling direction of the target train based on the speed change information acquired by each speed sensor (i.e., speed measuring module).
In practical application, the speed measuring module can output positive and negative values according to the movement direction of the target train: when the target train moves towards the speed measuring module, the speed fed back by the speed measuring module is a positive value; when the target train runs back to the speed measuring module, the speed fed back by the speed measuring module is a negative value.
The running direction of the target train can be determined through the positive and negative values output by the speed measuring module, and the target speed measuring sensor can be determined based on the running direction to serve as a source of the speed change information of the target train after the arrival direction of the target train is distinguished.
The process of detecting the second group length is specifically described below with reference to fig. 5 to 6:
1) FIG. 5 is one of the schematic diagrams of the determined target speed sensor provided by the present invention;
in FIG. 5, there are two target trains (8 consist trains, including cars 1-8; 17 consist trains, including cars 1-17, respectively); two speed measuring modules (namely speed measuring sensors 1-2) and four distance measuring modules (namely distance measuring sensors 1-4) are arranged at the platform; the modules are connected through a field bus and are connected to a dispatching control module (such as a dispatching control server) in the platform door equipment room; the dispatching control module sends a door opening and closing instruction to the central control panel based on data transmitted by the field bus.
When the target train enters from the right side, the speed detected by the speed measuring module 1 at the left side of the platform is positive, the speed detected by the corresponding speed measuring module 2 at the right side is negative, and the speed measuring sensor 1 at the left side and the distance measuring module 1-2 (namely the distance measuring sensor) are used as data sources.
2) FIG. 6 is a second schematic diagram of the target determination speed sensor provided by the present invention;
in FIG. 6, there are two target trains (8 consist trains, including cars 1-8; 17 consist trains, including cars 1-17, respectively); two speed measuring modules (namely speed measuring sensors 1-2) and four distance measuring modules (namely distance measuring sensors 1-4) are arranged at the platform; the modules are connected through a field bus and are connected to a dispatching control module (such as a dispatching control server) in the platform door equipment room; the dispatching control module sends a door opening and closing instruction to the central control panel based on data transmitted by the field bus.
When the target train enters from the left side, the speed detected by the speed measuring module 2 at the right side of the platform is positive, the speed detected by the corresponding speed measuring sensor 1 at the left side is negative, and the speed measuring sensor 2 at the right side and the distance measuring sensors 3-4 (namely the distance measuring sensors) are used as data sources.
In the above embodiment, the target speed sensor is determined by determining the traveling direction of the target train; based on the speed change information acquired by the target speed sensor, the parking state of the target train can be accurately determined; and the accuracy of generating different control instructions can be improved based on the stop state, so that a platform door controller can control the opening or closing of the platform door based on the target control instructions, and the aim of automatically controlling the operation of the platform door according to the train type information is fulfilled.
Optionally, in one possible implementation manner of the embodiment of the present invention, the determining, based on the vehicle type information and the parking status, a target control instruction, and sending the target control instruction to a platform door controller may be specifically implemented by the following manner:

It should be noted that, the scheduling control server stores a comparison table (i.e. a preset control instruction comparison table) of the vehicle type information and the door opening instruction of the target train, the scheduling control server finds the door opening instruction (i.e. the first target control instruction) corresponding to the vehicle type information of the target train in the preset control instruction comparison table through the extracted vehicle type information, and sends the door opening instruction to a central control panel (i.e. a platform door controller) of the platform door system, and the central control panel controls the corresponding sliding door to be opened according to the first target control instruction.
In mode 2, when the stop state of the target train is the start stop, the dispatch control server transmits a door closing command (i.e., a second target control command) to the central control panel of the station door system, and the central control panel controls all sliding doors to be closed.
The unopened sliding door keeps still when receiving the instruction in the process, and the unopened sliding door is closed when receiving the instruction, so that the door closing instruction does not need to be distinguished according to the vehicle type information.
In the above embodiment, the target control instruction is determined based on the vehicle type information and the parking state, and the target control instruction is sent to the platform door controller, so that the platform door controller controls the platform door based on the target control instruction, thereby achieving the goal of automatically controlling the operation of the platform door according to the train type information, improving the station operation efficiency, and further promoting the intelligent development process of the platform door system.
