Traditional railway station platform ground guide signs are painted, set up flat signs with a color different from the floor tiles, or set up metal landmarks. However, there are many reasons such as easy wear and tear, easy confusion by color distinction, single function, and unsightly appearance, making it difficult for passengers to quickly and accurately obtain relevant guidance information such as train numbers and carriages.

[0003] With the development of high-speed railways, the number of EMU models continues to increase. Different trains will stop on the same railway, and there are many train formation methods. The stop positions and car numbers of different trains are different. When waiting for the train on the platform, passengers do not know where the starting position of the train they are taking is, where the car door is, and after the train stops, passengers will cause confusion when looking for the car they are taking, which affects safety. In order to guide passengers to quickly find their own car, electronic landmarks are usually set up on the platform to guide passengers waiting for the train.

[0052] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0054] Unless otherwise specified, the term "plurality" means two or more than two. In the disclosed embodiments, the character " / " indicates that the objects before and after are in an "or" relationship. For example, A / B means: A or B. The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0055] At present, some stations have installed electronic landmarks. There are three common types, but they have shortcomings to varying degrees:

[0056] The first type is a hanging general LED display screen. The screen is far away, but it cannot be hung outside the rainproof awning. It is expensive and cannot cover all train carriages. The hanging general LED display screen can prompt users about the approximate location of the carriage at the front, middle or rear of the train. Users still need to find the carriage by themselves, and the prompt is not specific enough.

[0057] The second type is underground LCD screens, which can only be used in fully enclosed platforms due to the inherent defect of insufficient brightness of LCD screens, and the effect is not good even in fully enclosed platforms.

[0058] The third category is the underground general LED display screen, which is composed of a general display screen module and a general transmission module. It is large in size, high in price, unsightly and impractical.

[0059] The electronic landmark provided in the embodiment of the present application is an LED display screen specially used to guide passengers to queue up at the platform. It adopts an underground design, and the size of the display screen is customized according to the display guidance information. It is small, beautiful and practical, and can also display slogans.

[0060] Among them, electronic landmarks are set near the doors of trains corresponding to different types of vehicles when the train stops at the platform. In order to achieve accurate reminders for carriages of different types of vehicles, this embodiment provides a comprehensive management system to group and manage multiple electronic landmarks, and realize the content display, brightness and alarm prompt management of electronic landmarks.

[0061] In order to make the purpose, technical solutions and advantages of the present application clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0062] Figure 1 This is a schematic diagram of the structure of a system for controlling ground electronic landmarks provided in one embodiment of the present application. Figure 1 As shown, the system for ground electronic landmark control includes a plurality of electronic landmarks 10 laid on the ground of at least one platform, a communication main module 11, a network switch 12 and a host computer 13. In the figure, three platforms are shown as an example.

[0063] Each electronic landmark 10 includes a communication submodule and an LED display panel for displaying train guidance information and / or slogan prompt information. The LED display panel includes a plurality of LED pixel units arranged in an array. The LED pixel unit is a multi-color LED pixel unit.

[0064] In a possible implementation, the electronic landmark 10 is only used to display train guidance information.

[0065] In a possible implementation, the electronic landmark 10 is used to display train guidance information and slogan prompt information.

[0066] Optionally, train guidance information and slogan prompt information are displayed simultaneously in different areas, with simple control logic, reducing the control operation pressure of the host computer.

[0067] Optionally, train guidance information and slogan prompt information are displayed alternately according to the set switching time, which can interact with passengers and reduce passenger fatigue while waiting for the train.

[0068] Optionally, some of the electronic landmarks 10 in the guidance landmark group are used to display train guidance information, and other electronic landmarks 10 are used to display slogan prompt information, which can play the role of guidance and slogan prompt at the same time, avoiding passengers from being unable to clearly obtain guidance information in emergency boarding situations.

[0069] Each station is provided with a corresponding communication main module 11. A plurality of electronic landmarks 10 on each station are connected to the corresponding communication main module 11 through a communication submodule. Each communication main module 11 is connected to a host computer 13 through a network switch 12.

[0070] The host computer 13 is used to manage train information, display scheme configuration information and landmark grouping, determine the corresponding guidance landmark group according to the train information of the train to be stopped at the platform, determine the display information of each electronic landmark 10 in the guidance landmark group according to the train information and the display scheme configuration information, and send the display information via the network switch 12 and the communication main module 11; wherein, the display information includes: train guidance information and / or slogan prompt information.

[0071] The electronic landmark 10 is used to receive the display information transmitted by the communication main module 11 through the communication submodule.

[0072] In this embodiment, the electronic landmark control system includes: an electronic landmark, a communication main module, a network switch and a host computer. Among them, the electronic landmark adopts an LED display panel including a plurality of LED pixel units arranged in an array, which saves the cost of the electronic landmark display device, and the display effect is not easily affected by the environment, and can be more eye-catching and play a guiding effect. In addition, the LED pixel unit adopts a multi-color LED pixel unit, which can enrich the display scheme. The host computer is used to manage the train information of the train to be stopped at the platform, manage the display scheme configuration information of the electronic landmark, and control each of the electronic landmarks to display the train guidance information and slogan prompt information; wherein, the train information includes: basic train information and train stop information. The train management module realizes the comprehensive management of multiple electronic landmarks, and integrates the design of the electronic landmark LED display panel to improve the management efficiency and guidance prompt efficiency of the electronic landmark.

[0073] Figure 2 The system architecture diagram of the host computer provided in one embodiment of the present application. The host computer is installed with an electronic landmark management program. Figure 2 As shown, the electronic landmark management program includes: a presentation layer and a persistence layer.

[0074] Among them, the presentation layer includes landmark management module, train management module, configuration management module and operation management module; the persistence layer includes a database; the landmark management module and the operation management module are respectively connected to the electronic landmarks in communication; the landmark management module, train management module, configuration management module and operation management module are respectively connected to the database.

[0075] The database is used to store electronic landmark information, display scheme configuration information, vehicle type-platform-landmark mapping table and train information of trains to be parked at the platform.

[0076] The train management module is used to manage the train information of the trains to be stopped at the platform, and when receiving the train delay information sent by the external device, update the train information in the database based on the train delay information;

[0077] The configuration management module is used to manage the display scheme configuration information of the electronic landmark and update the display scheme configuration information in the database when receiving the display scheme configuration information.

[0078] The landmark management module is used to manage the landmark identification and landmark grouping of multiple electronic landmarks, and determine the corresponding guidance landmark group according to the train information of the train to be stopped at the platform.

[0079] The operation management module is used to poll the database for train information of trains to be stopped at the platform, and to receive train information of trains to be stopped at the platform sent by external devices, and to determine the corresponding guidance landmark group according to the train information of the trains to be stopped at the platform, and to determine the display information of each electronic landmark in the guidance landmark group according to the train information and display scheme configuration information.

[0080] In this embodiment, the electronic landmark management program in the upper computer includes a presentation layer and a persistence layer. The presentation layer is provided with a landmark management module, a train management module, a configuration management module and an operation management module, which comprehensively realize train information management, display scheme configuration information management and landmark display control, and control each electronic landmark to display train guidance information and slogan prompt information according to the train information and display scheme configuration information in the database, thereby improving the efficiency of electronic landmark display control and enriching the electronic landmark display content.

[0081] Figure 3a This is a schematic diagram of the structure of an electronic landmark display panel provided in one embodiment of the present application. Figure 3a As shown, the LED display panel includes a plurality of LED pixel units arranged in an array; the LED pixel units are multi-color LED pixel units.

[0082] In one possible implementation, Figure 3b As shown, the multiple LED pixel units of each electronic landmark are divided into a train number display area, a carriage display area and a direction prompt display area. The specific display effect is as follows Figure 3b The display screen size is customized according to the display guidance information, which is small, beautiful and practical, and optimizes the display effect of the prompt information to make the display more eye-catching.

[0083] In other possible implementations, the distribution order of the train number display area, the carriage display area and the direction prompt display area can be adjusted, such as Figure 3c and 3e In other possible implementations, in order to increase the display area to enrich the display content, no obvious area division is performed when arranging the LED pixel units, such as Figure 3g As shown, a relatively large rectangular display area on the LED display panel, the specific display content includes but is not limited to Figure 3b , 3d and 3f.

[0084] In a possible implementation, each electronic landmark also includes a slogan display area (not shown in the figure). The slogan display area is displayed in a solid-state printed display or a dynamic display. The slogan display area is used to display one or more of the following: civilized norms slogan information, inspirational slogan information, and safety propaganda slogan information. Optionally, the slogan display area is distributed in Figure 3a~3f In the figure, both sides of the carriage display area are used to fully utilize the space of the display panel and avoid increasing the size of the electronic landmark.

[0085] In one possible implementation, each electronic landmark also includes a display unit for a slogan display area; the display unit is one or more of a night scene display unit, an LED display unit, an OLED display unit, a QLED and QD-LCD display unit, a Miniled display unit or a Micro-LED display unit.

[0086] Among them, in order to facilitate passengers to better distinguish between train-related guidance information and slogans, the slogan display area uses other display units different from the multi-color LED pixel units, and the display brightness is controlled to be lower than the multi-color LED pixel units. The differentiated display avoids affecting the eye-catching display of the guidance information, and at the same time can achieve a richer and more diverse display effect for the slogan information.

[0087] In this embodiment, the electronic landmark uses an LED display panel including a plurality of LED pixel units arranged in an array, which saves the cost of the electronic landmark display device, and the display effect is not easily affected by the environment, and can be more eye-catching and play a guiding effect. In addition, the LED pixel unit uses a multi-color LED pixel unit, which can enrich the display scheme.

[0088] In a possible implementation, the display scheme configuration information includes one or more of display content, display content switching scheme, foreground color, background color, font, and font color.

[0089] The displayed content includes train number, carriage and direction prompt. Figure 3b , 3d As shown in 3f, after the train enters the station, only part of the LED pixel units of the display content are lit to display the train number, carriage and direction prompts. Optionally, in order to distinguish different models, when the train number, carriage and direction prompts are given, all LED pixel units of the LED display panel are lit, and different LED pixel units display different colors (not shown in the figure). For example: the pixel units used to prompt the train number, carriage and direction use the same color as the foreground color, and other pixel units display other colors as the background color. The background color or foreground color is adjusted according to the model to distinguish the model.

[0090] The display content switching scheme includes: one or more of the screen-up time, screen-down time or display sequence. For example, the screen-up time is 5 to 10 minutes before the train arrives at the station, so that the station crew can manually check whether the display content is correct before the passengers wait for the train, or confirm the presence of a faulty landmark so as to arrive near the faulty landmark in advance and manually guide the passengers. The screen-down time is 1 to 2 minutes after the train leaves the station.

[0091] Display timing is used to control flashing reminders, for example: flashing reminders 30 seconds to 1 minute before the train departs, to remind passengers to board the train as soon as possible, reduce the frequency of manual reminders, and avoid untimely manual reminders or panic. Display timing includes one or more of holding time, moving speed and pause time.

[0092] In a possible implementation, the landmark identifier includes: a MAC address of the electronic landmark, a primary key of the electronic landmark in the electronic landmark system, and a primary key of the electronic landmark in the system.

[0093] The MAC address of the electronic landmark is set by the manufacturer in the form of a serial code. The primary key of the electronic landmark in the system is the electronic landmark identifier recorded in the database, which is specifically identified by the location of the electronic landmark on the platform using a serial code or array method. For example, the serial code method 0123 or the array method 3-23 are both the 23rd landmark on platform 3.

[0094] In this implementation, the landmark grouping management of multiple electronic landmarks is mainly used for grouping management according to vehicle type and stop platform, ensuring that the electronic landmarks at the car door positions corresponding to the vehicle type are lit when the vehicle is parked, and the electronic landmarks far away from the car door positions are dormant or display slogan information, so as to improve the prompt effect of the electronic landmarks used for prompts and reduce the energy consumption of the overall electronic landmarks.

[0095] Optionally, the landmark grouping includes a guidance landmark group and a slogan landmark group. The guidance landmark group is a landmark near the corresponding carriage door for displaying train-related guidance information, and the slogan landmark group is a landmark away from the carriage door and different from the guidance landmark group. The electronic landmarks of the slogan landmark group can be used as landmarks in the guidance landmark group when other models of vehicles stop, and the electronic landmarks of the guidance landmark group can be used as landmarks in the slogan landmark group when other models of vehicles stop.

[0096] In the embodiment of the present application, the working state of the electronic landmark includes a display state and a sleep state.

[0097] Optionally, before the landmark management module performs corresponding display control on the electronic landmark according to the train prompt information and the display scheme configuration information, it also includes controlling the electronic landmark to switch from a sleep state to a working state.

[0098] Optionally, when the landmark management module receives the display information transmitted by the communication main module through the communication submodule, it actively switches from the sleep state to the working state.

[0099] In this embodiment, the electronic landmark switches between a display state and a sleep state to ensure that when there is no flow of people on the platform, the energy consumption of the electronic landmark is reduced, the energy-saving effect is improved, and a striking reminder is provided when there is flow of people on the platform.

[0100] In one possible implementation, the presentation layer further includes: an electronic landmark operation management module for managing one or more of the brightness, fan, temperature, and operation status alarms of the electronic landmark;

[0101] The configuration management module is also used to manage configuration information of one or more of the brightness, fan, temperature and operation status alarm of the electronic landmark;

[0102] The database is also used to store configuration information of one or more of the brightness, fan, temperature and operation status alarms of the electronic landmark.

[0103] Among them, the brightness configuration information can be configured for all landmarks in the station as a whole or in groups according to platform distribution or regional distribution. For example, the brightness of some electronic landmarks affected by natural light at both ends of the platform can be configured, and the brightness during noon is higher than that during night.

[0104] Similarly, the heat dissipation module configuration information can be configured for all landmarks in the station as a whole or in groups according to platform distribution or regional distribution. Among them, some electronic landmarks at both ends of the platform affected by natural light have high heat and need to be cooled in time.

[0105] In addition, the alarm item configuration information can be configured for all landmarks in the station as a whole or in groups according to platform distribution or regional distribution. For example, for high temperature alarms, some electronic landmarks at both ends of the platform affected by natural light have high heat. If the same high temperature alarm condition is set, the alarm frequency of some electronic landmarks at both ends of the platform affected by natural light will increase. Then, configuring alarm items by region can optimize the management of electronic landmarks.

[0106] In this implementation, the safe operation of electronic landmarks is managed through the cooperation of the electronic landmark operation management module, configuration management module and database module at the presentation layer. When the electronic landmark is at risk of high temperature or low temperature, an alarm is issued in time to remind relevant personnel to conduct maintenance, ensure the safe operation of electronic equipment, extend the service life of electronic equipment, and avoid potential safety hazards and economic losses.

[0107] In different embodiments, the operation control of the electronic landmark is performed in different ways according to the configuration information of the configuration management module.

[0108] In a possible implementation, the landmark management module is responsible for forwarding configuration information to the corresponding electronic landmark, and the internal control system of the electronic landmark performs brightness control, heat dissipation control or alarm control.

[0109] In a possible implementation, the landmark management module is also used to perform operation control on the electronic landmark. The operation control includes one or more of brightness control, heat dissipation control, and alarm control, that is, the landmark management module sends a brightness control instruction or a heat dissipation control instruction to the corresponding electronic landmark, and performs alarm judgment and prompts according to the operating parameters such as the temperature of the electronic landmark.

[0110] Figure 4 is a flowchart of the method for controlling ground electronic landmarks provided in an embodiment of the present application, such as Figure 4 As shown, the method comprises the following steps:

[0111] S401, determining a corresponding guidance landmark group according to the train information of the train to be stopped at the platform; wherein the train information includes: basic train information and train stop information.

[0112] In the embodiment of the present application, the method execution subject is a host computer in a system for controlling ground electronic landmarks.

[0113] In different embodiments, the train information of the train to be stopped is obtained in different ways.

[0114] In a possible implementation, before step S301, it also includes: polling the train information stored in the local database to determine the train information of the train to be stopped at the platform; or, receiving the train information of the train to be stopped at the platform sent by an external device, and when the train delay information is received, updating the train information in the local database based on the train delay information.

[0115] Specifically, the train passing information and time of each station are relatively fixed. When encountering peak traffic during holidays or unexpected weather conditions, trains may be delayed or suspended. When there are no special circumstances, the landmark management module in the host computer polls the database and determines the trains to be parked at the platform according to the train arrival time. When special circumstances occur, the delay or suspension notice sent by the train operation management system or manually configured by the staff is received.

[0116] In this implementation, the corresponding guidance landmark group is determined based on polling the local database and receiving train information of trains to be stopped at the platform sent by external devices, so as to realize dynamic adjustment of the electronic landmark display and improve the management efficiency and guidance prompt efficiency of electronic landmarks.

[0117] S402: Determine display information of each electronic landmark in the guide landmark group according to the train information and display scheme configuration information, wherein the display information includes: train guide information and / or slogan prompt information.

[0118] In the specific implementation process, the station includes multiple platforms, and when trains of different models stop at the same platform, the landmarks corresponding to the carriages are different. Therefore, in order to improve the eye-catching effect to effectively remind passengers and reduce the energy consumption of the overall electronic landmarks, the electronic landmarks need to be grouped.

[0119] S403, sending the display information to control one or more areas on the LED display panel of the electronic landmark to display; wherein each display area is composed of a plurality of LED pixel units.

[0120] In this embodiment, the corresponding guide landmark group is determined according to the train information of the train to be stopped at the platform, and the display information of each electronic landmark in the guide landmark group is determined according to the train information and the display scheme configuration information and the display information is sent to control the display of multiple areas on the LED display panel of the electronic landmark. This application realizes the comprehensive management of electronic landmarks, train information and display scheme configuration information, and combines the design of displaying electronic landmarks through array-arranged LED pixel units, thereby improving the management efficiency and guidance prompt efficiency of electronic landmarks.

[0121] In a possible implementation, the display scheme configuration information includes one or more of display content, display content switching scheme, foreground color, background color, font, and font color.

[0122] In different embodiments, the specific information form of the displayed information is different, and accordingly, the upper screen display mode of the electronic landmark is different.

[0123] In a possible implementation, the display information is dot matrix control information, so as to control the electronic landmark to light up the corresponding LED pixel unit according to the dot matrix control information.

[0124] Among them, the dot matrix control information includes: the dot matrix control information includes: the electronic landmark identification, the LED pixel unit to be lit, the display position, the display area and the display color corresponding to the pixel unit; the electronic landmark identification is the MAC address of the electronic landmark or the primary key of the electronic landmark in the system.

[0125] In this implementation, the host computer directly generates dot matrix control information for controlling the LED pixel units of the electronic landmark based on the train information and display scheme configuration information, so that when the electronic landmark receives the dot matrix control information, it can quickly light up the corresponding LED pixel unit, thereby improving the guidance prompt efficiency.

[0126] In another possible implementation, the electronic landmark has an independent control system that can generate dot matrix control instructions based on display information to control corresponding LED pixel units to light up with corresponding colors.

[0127] In this implementation, the host computer generates text or picture information based on the train information and display scheme configuration information, and the electronic landmark generates dot matrix control information based on the display information and controls the corresponding LED pixel units to light up.

[0128] In another possible implementation, for situations where the displayed content is complex, or where multiple electronic landmarks are used to display the same content, the landmark management module generates a dot matrix control instruction and sends it to the corresponding electronic landmark, which can increase the information display rate on the screen. For situations where the displayed content is simple, the electronic landmark generates the corresponding dot matrix control instruction to reduce the computing pressure of the host computer.

[0129] Specifically, when an electronic landmark includes a slogan display area, if there is a picture sign such as "No Smoking", the landmark management module generates a dot matrix control instruction and sends it to one or more electronic landmarks for unified display. As for train guidance information, based on the difference between the car number displayed by each electronic landmark and the car numbers pointing to the front and back, the landmark management module directly sends content display control information to the electronic landmark, and each electronic landmark generates and displays the array control instruction by itself, which can improve the efficiency of the upper screen display of the guidance information.

[0130] Based on this, in a possible implementation manner, before sending the display information, the process includes:

[0131] When the display information is text prompt information and / or digital prompt information, generating content display control information based on the text prompt information and / or digital prompt information, and using the content display control information as the display information to be sent;

[0132] When the display information is picture prompt information, dot matrix control information is generated based on the picture prompt information, and the dot matrix control information is used as the display information to be sent.

[0133] Among them, the text prompt information is the train type such as: G, Z, T, K, front, back, etc., and the digital prompt information is mainly the train number and car number 1, 2,..., 0, etc.

[0134] In one possible implementation, the train prompt information includes: any one of the train entry, exit or train itinerary change information, and the train number; wherein the train itinerary change information includes any one of the delay information, early arrival information and platform change information.

[0135] In a possible implementation, when the train guidance information is exit information, it further includes:

[0136] After the train leaves the platform for a set time, a sleep instruction is generated and sent to each electronic landmark in the corresponding guidance landmark group to instruct the electronic landmark to enter the sleep state from the working state.

[0145] S505, determining the display information of each electronic landmark and generating an on-screen list.

[0146] The displayed information includes: train guidance information and / or slogan prompt information.

[0147] Optionally, the train guidance information includes: any one of the train entry, exit or train itinerary change information, and the train number; wherein the train itinerary change information includes any one of the delay information, early arrival information and platform change information.

[0148] S506, determine whether the screen display time has arrived. If the screen display time has arrived, execute step S507; otherwise, wait for the screen display.

[0149] S507, determine whether to display picture prompt information on the screen. If the picture prompt information is displayed on the screen, execute step S508, otherwise, if the text prompt information and / or digital prompt information is displayed on the screen, execute step S509.

[0150] S508, generating dot matrix control information according to the template setting and the picture prompt information.

[0151] S509, sending a screen display instruction to the electronic landmark according to the protocol.

[0159] In this implementation, a landmark grouping list is preset in advance according to the station operation situation, and determining the guiding landmark group based on querying the landmark grouping list can improve the efficiency of displaying information on the screen.

[0160] Among them, Figure 6 As shown, the operations of establishing a landmark grouping list include:

[0168] Based on this implementation, in actual application, for the same station, all trains that stop at it have corresponding platforms, but there are inevitable temporary changes, or the train stop platforms are changed according to the station plan. Therefore, the vehicle type-platform-landmark mapping table is updated to facilitate subsequent direct calls.
