[0002] In recent years, platform screen door systems have been widely adopted on some intercity and high-speed railways. Currently, most stations control the opening and closing of platform screen doors manually via a local control panel installed on the platform.

[0003] However, in the relevant technologies, for each type of train, a corresponding door opening control button is set on the local control panel. This requires station staff to be able to identify the type of train currently entering the station and execute the corresponding operation accurately. If the button operation is wrong and the platform door outside the train formation range is opened, it will cause a great safety hazard.

[0004] Therefore, how to automatically and accurately send opening and closing commands to control the platform door system is an important issue that the industry urgently needs to address. Summary of the Invention

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0048] To facilitate a clearer understanding of the various embodiments of this application, some relevant background knowledge will be introduced as follows.

[0049] In recent years, platform screen door systems have been widely adopted on some intercity and high-speed railways. However, the types of trains operating on the same line are quite complex and diverse. Some older train models only use Automatic Train Protection (ATP) control and do not have the relevant functions of Automatic Train Operation (ATO). If they were to be upgraded, the cost would be huge, so it is impossible to achieve the linkage control with the signaling system as in urban rail transit.

[0050] In related technologies, most stations control the opening and closing of platform screen doors by manually operating a local control panel installed on the platform. For each type of train, the local control panel is equipped with a corresponding door opening control button. This requires station staff to be able to identify the type of train currently entering the station and execute the corresponding operation accurately. If the button is operated incorrectly and the platform screen door is opened outside the train formation range, it will cause a great safety hazard.

[0051] As passenger transport sectors increasingly demand automatic control of platform screen doors, several automatic control technologies for platform screen doors have emerged in the industry, including image recognition technology and millimeter-wave radar detection technology.

[0052] Image recognition technology uses cameras to capture real-time images of stations and analyzes the type of train entering the station and its stopping accuracy. However, this method is susceptible to external environmental factors such as weather, vibration, and light intensity, and cannot guarantee stability and reliability.

[0053] Millimeter-wave radar detection technology detects trains entering and leaving the station by capturing moving objects on the track, thereby controlling the platform screen doors to perform corresponding actions. This method cannot identify the specific train model and can only achieve automatic control of the entire or half of the platform screen doors.

[0054] Therefore, in order to address the aforementioned technical problems and to enable the automatic and accurate sending of opening and closing commands to control the platform screen door system, this invention provides a platform screen door control method, device, electronic equipment, and storage medium.

[0055] The following is combined with Figure 1 The platform screen door control method provided by the present invention will be described in detail. Figure 1 This is one of the flowcharts illustrating the platform door control method provided by the present invention. See [link / reference]. Figure 1 As shown, the method includes steps 101-103, wherein:

[0056] Step 101: Obtain the scheduling data of the target train; the target train is a train waiting to enter the station, and the scheduling data includes the first train length and model information of the target train, wherein the first train length is the preset train length of the target train.

[0057] First, it should be noted that the subject of this invention can be any electronic device with platform screen door control function, such as any kind of smartphone, smartwatch, desktop computer, laptop computer, etc., or a dispatch control server installed in the station's equipment room.

[0058] In order to automatically and accurately send opening and closing commands to control the platform screen door system, in this embodiment of the invention, it is first necessary to obtain the scheduling data of the target train, wherein the target train is the train waiting to enter the station (about to enter the station), and the first train length of the target train is the preset train length of the target train in the scheduling data.

[0059] In practical applications, the implementing entity can connect to the China State Railway Group's dispatching system through the railway intranet and obtain real-time dispatching data of the target trains that are about to enter the station.

[0060] Specifically, the dispatching data for target trains obtained from the China State Railway Group's dispatching system mainly includes:

[0061] A. Daily Schedule: Includes train timetable information, including planned arrival time, planned departure time, arriving train number, departing train number, and stopping track.

[0062] B. Phase Plan: The phase plan is a plan every three hours, used to adjust the planned arrival time and planned departure time of the train.

[0063] C. Actual Arrival and Departure: Actual train information, including actual arrival time, actual departure time, actual arrival train number, and actual departure train number.

[0064] D. Timetable: Includes stops and estimated stay time.

[0065] E. Trainset Plan: Trainset plan is used to obtain train model information, and the train formation length can be calculated based on the train model information.

[0066] Step 102: Obtain the second train length and stopping status of the target train; match the second train length with the first train length; the second train length is the actual train length of the target train, and the stopping status includes at least entering the station and stopping and departing from the station.

[0067] In this embodiment, after obtaining the scheduling data of the target train, it is also necessary to obtain the second train length and stopping information of the target train; then the second train length is matched with the first train length.

[0068] The second train length is the actual train length of the target train entering the station. It should be noted that by matching the second train length with the first train length, the accuracy of the data corresponding to the target train in the dispatching system can be verified.

[0069] The target train stopping information is used to indicate the running status of the target train after it enters the station. The stopping information includes at least: coming to a complete stop upon entering the station, starting from departure, and the train passing through the station.

[0070] Step 103: If the second train length and the first train length are successfully matched, a target control command is determined based on the vehicle type information and the parking status, and the target control command is sent to the platform door controller; the target control command is used by the platform door controller to control the opening or closing of the platform door.

[0071] In this embodiment, the length of the second train group is matched with the length of the first train group. If the match is successful, it indicates that the target train actually entering the station matches the scheduling information of the target train in the scheduling system. Then, the target control command is determined based on the model information and stopping status of the target train, and the target control command is sent to the platform door controller so that the platform door controller can control the platform door to open or close based on the target control command.

[0072] The platform screen door control method provided by this invention acquires the scheduling data of the target train, including the first train length and model information, where the first train length is a preset train length. Then, it acquires the second train length and stopping status, where the second train length is the actual train length, and the stopping status includes at least arrival at the station and departure from the station. The second train length is matched with the first train length; a successful match indicates that the actual train entering the station matches the scheduling information of the target train. Based on the model information and stopping status, a target control command is determined and sent to the platform screen door controller, enabling the platform screen door controller to start or close the platform screen doors based on the target control command. This achieves the goal of automatically controlling the operation of the platform screen doors according to the train model information, improving station operating efficiency and further promoting the intelligent development of platform screen door systems.

[0073] Optionally, in one possible implementation of the present invention, at least one distance sensor and a speed sensor are installed on the platform;

[0074] The acquisition of the second trainset length and stopping status of the target train can be achieved through the following methods, specifically including steps 1) to 4):

[0075] Step 1) Obtain the distance information collected by each of the ranging sensors, wherein the distance information is the distance between the ranging sensor and the object that is blocking the ranging sensor;

[0076] Step 2) Determine the second grouping length based on the distance information provided.

[0077] Step 3) Obtain the speed change information collected by each of the speed sensors, the speed change information reflecting the speed change of the target train;

[0078] Step 4) Determine the docking status based on the speed change information.

[0079] In this embodiment, the distance sensor is installed on the crossbeam of the platform gate to collect distance in a direction facing the track and perpendicular to the track.

[0080] For example, four sensors are deployed on each platform, located at the positions corresponding to the 4th, 5th, 12th, and 13th carriages, respectively. When the target train enters the station, distance information collected by each distance sensor can be obtained, and the length of the second train group can be determined based on this distance information.

[0081] Speed ​​sensors are installed on the gate pillars or beams at both ends of the platform, facing the track to acquire speed change information collected by each speed sensor in real time, and determine the stopping status of the target train based on the speed change information.

[0082] In the above implementation, distance information collected by each ranging sensor and speed change information collected by each speed sensor are acquired respectively. Then, based on the distance information, the length of the second train set is determined; based on the speed change information, the stopping status is determined. Through the above method, the length of the second train set can be used to determine whether the actual target train entering the station matches the scheduling information of the target train in the scheduling system. If they match, the stopping status of the target train (i.e., entering the station and stopping, departing and starting, and passing through the station) can be used to determine different control commands, so that the platform door controller can control the platform door to open or close based on the target control command, thereby achieving the goal of automatically controlling the operation of the platform door according to the train type information.

[0083] Optionally, in one possible implementation of the present invention, determining the second grouping length based on the distance information can be achieved through the following steps [1]-[2]:

[0084] Step [1]: Identify the ranging sensors whose distance information is less than and / or equal to a preset distance threshold as target ranging sensors;

[0085] Step [2]: Determine the second group length based on the number of target ranging sensors.

[0086] In this embodiment, after acquiring the distance information collected by each ranging sensor, a target ranging sensor needs to be selected from among the multiple ranging sensors to determine the second train group length. That is, ranging sensors whose distance information is less than and / or equal to a preset distance threshold are selected as the target ranging sensors for detecting the target train.

[0087] Then, based on the number of target ranging sensors, the length of the second train group is determined. For example, when a target train stops at the platform, the distance information collected by the ranging sensor (also called the ranging module) is the straight-line distance S from the installation position of the ranging module perpendicular to the track direction to the target train, and this S is used as a preset distance threshold.

[0088] When no train is stopped on the platform, the output data of the ranging module will be much larger than S. Therefore, a certain margin S1 is added to the value S and used as the basis for judgment. By comparing the output value of the ranging module with it in real time, it is possible to detect whether a train has entered.

[0089] Since current train formations are limited to 8, 16, and 17 cars, the length of the second car group can be detected simply by placing distance measuring modules at the 1 / 4 and 3 / 4 positions laterally on the platform. To ensure reliability, two sets of modules are placed at each location. The effective detection results from the four distance measuring modules on each side fall into three categories, which are described below. Figures 2-4 The process of detecting the length of the second group is explained in detail:

[0090] 1) Figure 2 This is one of the schematic diagrams provided by the present invention for determining the length of the second group;

[0091] exist Figure 2 In the system, there is a target train (an 8-car train, including carriages 1-8); two speed measuring modules (i.e., speed measuring sensors 1-2) and four distance measuring modules (i.e., distance measuring sensors 1-4) are installed at the platform; the modules are connected to each other via a fieldbus and connected to the dispatch control module (e.g., dispatch control server) in the platform door equipment room; the dispatch control module sends door opening and closing commands to the central control panel based on the data transmitted from the fieldbus.

[0092] If the distance measuring modules (i.e., distance measuring sensors 1-2 as target distance measuring sensors) installed in the 4th and 5th carriages of the platform detect the car body, and other modules do not detect it, then the target train is determined to be the first 8-car train, and the second car is 8.

[0093] 2) Figure 3 This is the second schematic diagram of determining the length of the second group provided by the present invention;

[0094] exist Figure 3 In the system, there is a target train (an 8-car train, including carriages 1-8); two speed measuring modules (i.e., speed measuring sensors 1-2) and four distance measuring modules (i.e., distance measuring sensors 1-4) are installed at the platform; the modules are connected to each other via a fieldbus and connected to the dispatch control module (e.g., dispatch control server) in the platform door equipment room; the dispatch control module sends door opening and closing commands to the central control panel based on the data transmitted from the fieldbus.

[0095] If the ranging modules (i.e., ranging sensors 3-4 as target ranging sensors) installed in the 12th and 13th carriages of the platform detect the car body, and other modules do not detect it, then the target train is determined to be the last 8-car train, with the second car group having a length of 8.

[0096] 3) Figure 4 This is the third schematic diagram of determining the length of the second group provided by the present invention;

[0097] exist Figure 4There is a target train (a 17-car train, including carriages 1-17); two speed measuring modules (i.e., speed sensors 1-2) and four distance measuring modules (i.e., distance sensors 1-4) are installed at the platform; the modules are connected to each other via a fieldbus and connected to the dispatch control module (e.g., dispatch control server) in the platform door equipment room; the dispatch control module sends door opening and closing commands to the central control panel based on the data transmitted from the fieldbus.

[0098] If all four ranging modules (i.e., ranging sensors 1-4 as target ranging sensors) detect the car body, then the target train is determined to be a 16 / 17 train set, with the second train set having a length of 16 / 17.

[0099] In the above implementation, by identifying ranging sensors whose distance information is less than and / or equal to a preset distance threshold as target ranging sensors, the second train length of the target train can be accurately determined based on the number of target ranging sensors. The second train length can be used to determine whether the actual target train entering the station matches the scheduling information of the target train in the scheduling system, thereby improving the accuracy of generating different control commands. This enables the platform door controller to control the opening or closing of the platform door based on the target control command, thus achieving the goal of automatically controlling the operation of the platform door according to the train model information.

[0100] Optionally, in one possible implementation of the present invention, determining the docking state based on the speed change information can be achieved through the following steps a)-c):

[0101] Step a) Determine the direction of travel of the target train based on the speed change information.

[0102] Step b) Determine the target speed sensor based on the driving direction;

[0103] Step c) Determine the docking status based on the speed change information collected by the target speed sensor.

[0104] In this embodiment, since the target trains enter the station in different directions, it is first necessary to determine the target speed sensor as the source of the target train speed change information. After determining the target speed sensor, the stopping status of the target train can be determined based on the speed change information collected by the target speed sensor, that is, it can be determined whether the target train needs to stop in the station or start from the station after entering the station.

[0105] Compared to passing trains, target trains that need to pick up and drop off passengers gradually decrease in speed as they enter the station, reaching zero speed when they arrive at the stop sign. After passengers have boarded and alighted, the target train starts moving, and its speed gradually increases accordingly.

[0106] The target speed sensor determines the train's entry into the station by capturing the process of the target train's speed decreasing. When the target train's speed reaches zero, after a short delay (computation time and filtering time), it is determined that the target train has come to a complete stop in the station. It should be noted that, to ensure the accuracy of the result, the distance information from the ranging module needs to be collected simultaneously, and the train will finally output a stop signal when the presence of a target train is verified.

[0107] Provided the target train's arrival and cessation signal is valid, the train's departure can be determined by capturing the speed increase process, and a corresponding signal will be output. Therefore, the target train departure signal can only be established after the train has started running.

[0108] The process of determining the direction of travel of the target train is described in detail below:

[0109] The direction of travel of the target train entering the station can be divided into two cases:

[0110] 1) Enter the station from the left when facing the track; 2) Enter the station from the right when facing the track.

[0111] Therefore, in order to distinguish the direction of the target train's entry into the station, it is necessary to determine the direction of travel of the target train based on the speed change information collected by each speed sensor (i.e., speed measurement module).

[0112] In practical applications, the speed measuring module can output positive or negative values ​​based on the direction of motion of the target train: when the target train is moving towards the speed measuring module, the speed measured by the speed measuring module is positive; when the target train is moving away from the speed measuring module, the speed measured by the speed measuring module is negative.

[0113] The direction of travel of the target train can be determined by the positive or negative value output by the speed measurement module. Once the direction of entry of the target train into the station is determined, the target speed measurement sensor can be used as the source of the target train speed change information based on the direction of travel.

[0114] The following is based on Figures 5-6 The process of detecting the length of the second group is explained in detail:

[0115] 1) Figure 5 This is one of the schematic diagrams of the target speed measuring sensor provided by the present invention;

[0116] exist Figure 5There are two target trains (an 8-car train, including carriages 1-8; and a 17-car train, including carriages 1-17). Two speed measuring modules (i.e., speed sensors 1-2) and four distance measuring modules (i.e., distance sensors 1-4) are installed at the platform. The modules are connected to each other via a fieldbus and connected to the dispatch control module (e.g., dispatch control server) in the platform door equipment room. The dispatch control module sends door opening and closing commands to the central control panel based on the data transmitted from the fieldbus.

[0117] When the target train enters the station from the right, the speed detected by the speed measuring module 1 on the left side of the platform is positive, while the speed detected by the speed measuring module 2 on the right side is negative. At this time, the speed measuring sensor 1 on the left and the distance measuring modules 1-2 (i.e., distance measuring sensors) are used as the data source.

[0118] 2) Figure 6 This is the second schematic diagram of the target speed measuring sensor provided by the present invention;

[0119] exist Figure 6 There are two target trains (an 8-car train, including carriages 1-8; and a 17-car train, including carriages 1-17). Two speed measuring modules (i.e., speed sensors 1-2) and four distance measuring modules (i.e., distance sensors 1-4) are installed at the platform. The modules are connected to each other via a fieldbus and connected to the dispatch control module (e.g., dispatch control server) in the platform door equipment room. The dispatch control module sends door opening and closing commands to the central control panel based on the data transmitted from the fieldbus.

[0120] When the target train enters the station from the left, the speed detected by the speed measuring module 2 on the right side of the platform is positive, while the speed detected by the speed measuring sensor 1 on the left side is negative. At this time, the speed measuring sensor 2 on the right side and the distance measuring sensors 3-4 (i.e., distance measuring sensors) are used as the data source.

[0121] In the above implementation, the target speed sensor is determined by determining the direction of travel of the target train; based on the speed change information collected by the target speed sensor, the stopping status of the target train can be accurately determined; and then the accuracy of generating different control commands can be improved based on the stopping status, so that the platform door controller can control the platform door to open or close based on the target control command, thereby achieving the goal of automatically controlling the operation of the platform door according to the train type information.

[0122] Optionally, in one possible implementation of this invention, the step of determining the target control command based on the vehicle model information and the parking status, and sending the target control command to the platform door controller, can be implemented in the following way:

[0123] Method 1: When the stopping state is that the target train has come to a complete stop at the station, a first target control command is determined based on the train model information and a preset control command lookup table, wherein the first target control command corresponds to the train model information;

[0124] The first target control command is sent to the platform door controller, and the first target control command is used to instruct the platform door vacant controller to open the platform door.

[0125] Method 2: When the stopping state is the departure and start of the target train, a second target control command is sent to the platform door control party. The second target control command is used to instruct the platform door vacant party to control all platform doors to close.

[0126] The following is a detailed description of Method 1 and Method 2:

[0127] Method 1: When the target train is in a station-entry and has come to a complete stop, the length of the second train group collected by the distance measuring sensor needs to be compared with the length of the first train group in the scheduling data. If the length of the second train group is the same as the length of the first train group, the scheduling data is deemed valid, and the train type information is extracted from the scheduling data.

[0128] It should be noted that the dispatch control server stores a lookup table of target train model information and door opening instructions (i.e., a preset control instruction lookup table). The dispatch control server finds the corresponding door opening instruction (i.e., the first target control instruction) in the preset control instruction lookup table by extracting the model information of the target train, and sends it to the central control panel of the platform door system (i.e., the platform door controller). The central control panel then controls the corresponding sliding door to open according to the first target control instruction.

[0129] Method 2: When the target train is in the process of starting to depart from the station, the dispatch control server sends a door closing command (i.e., the second target control command) to the central control panel of the platform door system, and the central control panel controls all sliding doors to close.

[0130] During this process, unopened sliding doors remain stationary upon receiving the instruction, while already opened sliding doors close upon receiving the instruction. Therefore, there is no need to differentiate closing instructions based on vehicle model information.

[0131] In the above implementation, the target control command is determined based on the train model information and the stopping status, and the target control command is sent to the platform door controller so that the platform door controller can control the platform door based on the target control command. This achieves the goal of automatically controlling the operation of the platform door according to the train model information, improves the station operation efficiency, and further promotes the intelligent development of the platform door system.

[0132] Optionally, in one possible implementation of the present invention, if the second group length fails to match the first group length, an alarm message needs to be generated, which is used to indicate that the scheduling data is incorrect.

[0133] In this embodiment, the length of the second train group collected by the ranging sensor is compared with the length of the first train group in the scheduling data. If the second train group length is the same as the first train group length, the scheduling data is considered valid; if the second train group length is different from the first train group length, the scheduling data is considered invalid, an alarm message is generated, and an audible and visual alarm is triggered to prompt manual intervention. This method detects the validity of the scheduling data, thereby avoiding the opening or closing of platform doors when the target train does not match the scheduling data, thus reducing safety hazards.

[0143] If the target train has come to a complete stop at the station, proceed to step 707; if the target train has started moving away from the station, proceed to step 708.

[0144] Step 707: Based on vehicle model information and a preset control command lookup table, determine the first target control command; send the first target control command to the platform door controller, which is used to instruct the vacant platform door controller to open the platform door.

[0145] Step 708: Send the second target control command to the platform door control party. The second target control command is used to instruct the platform door vacancy party to control all platform doors to close.

[0146] Step 709: Generate alarm information. The alarm information is used to indicate scheduling data errors.
