[0063] In order to enable persons skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0064] In view of the existing safety hazard problem of passengers crossing the line on the platform, the present invention provides a platform electronic safety line alarm device and method, which uses an LED display screen to identify the electronic safety line, and sets one or more safety modules including the LED display screen, and each safety module includes one or more LED display screens. In addition, a crossing line detector, a photosensitive detector, and a control module are set in each safety module; the crossing line detector detects the current position of the passenger on the platform, and after detecting that a passenger has crossed the safety line, it sends a crossing line detection signal to the control module; the photosensitive detector detects the ambient brightness, and sends a brightness detection signal to the control module. Accordingly, the control module can control the LED display screen to display the crossing line prompt information according to the crossing line detection signal, and can also control the brightness of the LED display screen according to the brightness detection signal.

[0065] like Figure 1 FIG. 1 is a schematic diagram of the structure of a platform electronic safety line alarm device according to an embodiment of the present invention.

[0066] In this embodiment, the device comprises: one or more security modules, Figure 1 The case of two security modules is shown in FIG.

[0067] Each safety module includes: a line crossing detector, a photosensitive detector, a control module, and a display module. The display module includes one or more LED display screens, and the LED display screen is used to identify the electronic safety line. Specifically, it can be set on the side of the platform close to the track and at a certain distance from the edge of the platform. The distance can be determined according to the position of the existing platform ground safety markings. The size of the LED display screen can be designed according to the length and width of the ground safety markings. Considering that the increase in the length of the LED display screen will incur higher costs, the length of each LED display screen can be determined based on the cost budget, and a display module can be designed with multiple LED display screens, such as 3 to 5.

[0068] In this embodiment, the crossing-line detector is used to detect the current position of the passenger on the platform, and after detecting that a passenger has crossed the safety line, sends a crossing-line detection signal to the control module; the photosensitive detector is used to detect the ambient brightness and sends a brightness detection signal to the control module.

[0069] Correspondingly, the control module outputs the line crossing prompt information (also called alarm information) to the display module according to the line crossing detection signal; and controls the brightness of the LED display screen according to the brightness detection signal.

[0070] The display module displays the line crossing prompt information on the LED display screen. The line crossing prompt information can be in the form of a flashing icon and / or text, etc., which is not limited in this embodiment of the present invention.

[0071] In practical applications, the line crossing detection signal may be a switch signal, and the brightness detection signal may be a resistance signal.

[0072] It should be noted that in actual applications, each security module can be designed to have a completely identical structure, for example, each includes its own processing unit. In addition, considering the cost issue, it can also be designed as a master-slave structure, that is, the security module includes: a master security module and one or more slave security modules; different security modules can be connected through serial data lines and networks.

[0073] The following is a detailed description of the device architecture of the master and slave structures.

[0074] like Figure 2 As shown, in this embodiment, the control module of each security module includes: a storage unit, and a signal sensing circuit, a resistance conversion circuit, and a video output module respectively connected to the storage unit.

[0075] For the main safety module, its control module also includes: a processing unit. Among them:

[0076] The signal sensing circuit is used to process the switch signal, such as rectification, voltage stabilization, etc., and write the line crossing information into the storage unit according to the processed switch signal;

[0077] The resistance conversion circuit is used to convert the resistance signal into a resistance value, and write brightness information into the storage unit according to the converted resistance signal;

[0078] The control module of the main safety module further includes: a processing unit, which is used to read the line crossing information and the brightness information stored in each storage unit, generate first video encoding data for line crossing alarm according to the line crossing information and the brightness information, and transmit the first video encoding data to each video output module;

[0079] The video output module is used to distribute the first video encoding data to each LED display screen in the corresponding display module for display.

[0080] It should be noted that the transmission of the above-mentioned line crossing information and brightness information can be completed through a serial data line such as RS232, and the transmission of the first video encoding data can be completed through a network (wired or wireless network).

[0081] The platform electronic safety line alarm device provided by the embodiment of the present invention uses an LED display screen to identify an electronic safety line, and is provided with one or more safety modules including the LED display screen, and each safety module includes one or more LED display screens. Moreover, a line crossing detector, a photosensitive detector, and a control module are provided in each safety module; the line crossing detector detects the current position of the passenger on the platform, and after detecting that a passenger has crossed the safety line, a line crossing detection signal is sent to the control module; the photosensitive detector detects the ambient brightness, and sends a brightness detection signal to the control module. Accordingly, the control module can control the LED display screen to display the line crossing prompt information according to the line crossing detection signal, and can also control the brightness of the LED display screen according to the brightness detection signal. Therefore, when a passenger crosses the safety line, an automatic and timely reminder can be given, and all-weather protection without blind spots can be achieved, which effectively improves the personal safety of passengers and driving safety, and greatly reduces the workload of platform security personnel.

[0082] Furthermore, in the case of multiple security modules, one of them is used as the main security module and interacts with the core server through the network, and the other modules are used as slave security modules and communicate with the main security module through the serial port data line and the network in turn. This device architecture can simplify the hardware configuration of the slave security module, reduce the cost of the slave security module, and thus save the cost of the entire device.

[0083] It should be noted that, considering that when passengers get on and off the train, for the convenience of description, the platform status at this time is called the boarding and alighting status. When the platform is in the boarding and alighting status, passengers need to cross the platform safety line, and the crossing line detector will detect that a passenger has crossed the safety line. In this case, it is a normal situation for passengers to get on and off the train, and the alarm information should not be displayed on the LED display. For this reason, in actual applications, the power switch of the device or the corresponding main safety module in the device can be controlled manually according to the arrival and departure of the train to avoid false alarms. In other words, the device is started to fully work only when the platform is in a non-boarding and alighting state. When the platform is in a boarding and alighting state, some or all of the modules or units in the device can be put into a dormant state, which not only avoids false alarms, but also effectively saves energy.

[0084] Reference Figure 3 , which is a specific application example of the platform electronic safety line alarm device according to an embodiment of the present invention.

[0085] In this embodiment, the device includes multiple safety modules, namely a main safety module and N slave safety modules. The display module of each safety module includes 5 LED display units, namely the LED display screen mentioned above. During installation, these LED display units are arranged in sequence and installed at a certain distance from the track side of the train platform as platform safety line markers.

[0086] The control module in the main safety module is used as a neighboring card, and the control modules in other slave safety modules are used as HUB cards. They are installed on the board interface in the safety module to which they belong. The boards of different safety modules can be connected through corresponding interfaces and data lines, such as setting corresponding wiring through holes on the installation boxes of each safety module. Each safety module can be powered by an external power supply, and the power line can also be connected to the board in each safety module through the through hole.

[0087] like Figure 3 As shown, in this embodiment, the device further includes: a core server, which is connected to the main security module via a network (wired network or wireless network).

[0088] The core server is used to send train arrival and departure information to the main safety module. Accordingly, the processing unit can determine the current state of the platform according to the train arrival and departure information, and transmit the first video encoding data to each video output module when the current state of the platform is a non-boarding or alighting state.

[0089] It should be noted that the train arrival and departure information can be manually input into the core server, or can be transmitted from the arrival and departure server to the core server, which is not limited in the embodiment of the present invention. Moreover, the arrival and departure server can be a part of the device of the present invention, or can be independent of the device, which is not limited in the embodiment of the present invention.

[0090] In the platform electronic safety line alarm device of this embodiment, the processing unit in the pilot card can automatically distinguish the current status of the platform according to the train arrival and departure information sent by the core server, avoiding false alarms when passengers get on and off the train. Compared with the manual control method, the automation and intelligence of the device can be further improved.

[0091] Furthermore, in this embodiment, the processing unit can also generate second video encoding data for indicating waiting information according to the train arrival and departure information, and transmit the second video encoding data to the video output module. Accordingly, the video output module distributes the second video encoding data to the LED display screens in each display module, so that the waiting information is displayed on the LED display screens.

[0092] It should be noted that the waiting information may include but is not limited to the following information: train number, arrival and departure time, stop platform, etc.

[0093] It can be seen that the solution of this embodiment can not only automatically warn passengers when they cross the line, but also provide passengers with clear and definite train information, effectively avoiding the situation where passengers get on the wrong train when there are trains on both sides of the platform.

[0094] Furthermore, in another specific application example of the device, the core server is also used to send advertising information to the main security module. Accordingly, the processing unit is also used to generate third video encoding data containing the advertising information, and transmit the third video encoding data to the video output module; the video output module is also used to distribute the third video encoding data to each LED display screen, so that the LED display screen displays the advertising information.

[0095] It should be noted that the advertising information, the waiting information, and the crossing line prompt information can be displayed in layers on the LED screen, wherein the advertising information is at the bottom layer, the waiting information is at the middle layer, and the crossing line prompt information is at the top layer, and the upper layer information can cover the lower layer information. In addition, the crossing line prompt information can be in the form of text, icons, patterns, etc., and of course it can also be a crossing line warning indication, such as the lights around the LED display screen flashing warning.

[0096] Furthermore, in another specific application example of the device, the device may also include: a broadcast unit and / or a display unit connected to the core server.

[0097] In this application example, the processing unit is further configured to package the line crossing information and the brightness information into a reporting information message and report the message to the core server via a network.

[0098] Correspondingly, the core server is further configured to send an out-of-line area message to one or more broadcast units and / or display units according to the reported information message. The broadcast unit performs out-of-line broadcasting according to the out-of-line area message; and the display unit performs out-of-line display according to the out-of-line area message.

[0099] The broadcast unit may include: a broadcast server and a player, wherein the broadcast server is used to generate an alarm audio file according to the cross-line area message; and the player is used to play the alarm audio file.

[0100] It should be noted that in actual applications, there may be one or more players, which may be specifically arranged on the corresponding platform. Similarly, the display unit may be one or more display screens arranged on the corresponding platform, so as to remind passengers of crossing the line through broadcasting and / or large-screen display and other methods to ensure the safety of passengers on the platform.

[0101] Furthermore, the core server can also send SMS notification information according to the reported information message to inform relevant personnel that a passenger has crossed the line, so that the relevant passengers can be reminded and intervened manually, and multiple measures can be adopted to better ensure the safety of passengers.

[0102] Furthermore, the core server may also provide the reported information message to other third-party application data interfaces, so that the third-party application performs relevant processing according to the message content, such as on-site video surveillance tracking, mobile text message publishing, etc.

[0103] Accordingly, the embodiment of the present invention also provides a platform electronic safety line alarm method, such as Figure 4 As shown, it is a flow chart of the method, comprising the following steps:

[0104] Step 401, respectively detect the current position of the passenger on the platform and the ambient brightness, and obtain a line crossing detection signal and a brightness detection signal.

[0105] The line crossing detection signal is generated after detecting that a passenger has crossed the security line.

[0106] Step 402: According to the line crossing detection signal, one or more LED display screens used to identify the electronic safety line are controlled to display line crossing prompt information, and the brightness of the LED display screens is controlled according to the brightness detection signal.

[0107] The platform electronic safety line alarm method provided by the embodiment of the present invention uses an LED display screen to mark the electronic safety line, and obtains a line crossing detection signal and a brightness detection signal by detecting the current position of the passenger on the platform and the ambient brightness respectively; according to the line crossing detection signal, one or more LED display screens used to mark the electronic safety line are controlled to display the line crossing prompt information, and the brightness of the LED display screen is controlled according to the brightness detection signal. Therefore, when a passenger crosses the safety line, an automatic and timely reminder can be given, and all-weather protection without blind spots can be achieved, which effectively improves the personal safety of passengers and driving safety, and greatly reduces the workload of platform security personnel.

[0108] Furthermore, in order to avoid false alarms of crossing the line when passengers get on or off the train when the platform is in the boarding or alighting state, in another embodiment of the method of the present invention, train arrival and departure information can also be obtained in real time. Accordingly, in the above step 402, it is necessary to determine the current state of the platform according to the train arrival and departure information, and when the current state of the platform is not in the boarding or alighting state, control the LED display screen to display the crossing line prompt information. In other words, only when the platform is not in the boarding or alighting state, will the LED display screen be prompted according to the crossing line prompt information. Figure 4 In the method of step 402 shown in FIG. 1 , once it is detected that a passenger has crossed the line, the corresponding crossing prompt information will be displayed on the LED display screen.

[0109] It should be noted that the cross-line prompt information may be a flashing icon and / or a striking sign composed of text, etc., to better remind passengers. Of course, the embodiment of the present invention does not limit the specific content and form of the cross-line prompt information.

[0110] Furthermore, in another embodiment of the method of the present invention, waiting information can be generated according to the train arrival and departure information, and the LED display screen can be controlled to display the waiting information, thereby providing passengers with clear and definite train information, effectively avoiding the situation where passengers get on the wrong train when there are trains on both sides of the platform.

[0111] Furthermore, in another embodiment of the method of the present invention, advertisement information may be obtained, for example, the advertisement information may be obtained from a core server, and the LED display screen may be controlled to display the advertisement information.

[0112] It should be noted that the advertising information, the waiting information, and the crossing line prompt information can be displayed in layers on the LED screen, wherein the advertising information is at the bottom layer, the waiting information is at the middle layer, and the crossing line prompt information is at the top layer, and the upper layer information can cover the lower layer information. In addition, the crossing line prompt information can be in the form of text, icons, patterns, etc., and of course it can also be a crossing line warning indication, such as the lights around the LED display screen flashing warning.

[0113] like Figure 5 FIG. 2 is another flow chart of the platform electronic safety line alarm method of the present invention, comprising the following steps:

[0114] Step 501, respectively detect the current position of the passenger on the platform and the ambient brightness, and obtain a line crossing detection signal and a brightness detection signal.

[0115] Step 502: According to the line crossing detection signal, control one or more LED display screens used to identify the electronic safety line to display line crossing prompt information, and control the brightness of the LED display screens according to the brightness detection signal.

[0116] Step 503: Pack the line crossing information generated according to the line crossing detection signal and the brightness information generated according to the brightness detection signal into a reporting information message, and report the reporting information message to the core server.

[0117] Step 504: the core server controls the off-line broadcast, and / or off-line display, and / or sends SMS notification information according to the reported information message.

[0118] For example, the players and display screens installed at the corresponding stations perform cross-line broadcasting and / or cross-line display.
