BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 It is a structural schematic diagram of the high-speed railway station landmark screen guidance system with intelligent monitoring and alarm functions of the present invention.

[0030] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0031] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0032] like Figure 1 As shown, the present invention provides a high-speed railway station landmark screen guidance system with intelligent monitoring and alarm functions, including a controller, a data acquisition module, a voltage acquisition module, an image acquisition module, a calculation module, a line crossing determination module, an audible and visual alarm, a sleep module, a shutdown module and a service platform, the controller is respectively connected to the data acquisition module, the voltage acquisition module, the line crossing determination module, the audible and visual alarm, the sleep module, the shutdown module and the service platform, the line crossing determination module is connected to the calculation module, and the calculation module is connected to the image acquisition module.

[0033] Data acquisition module:

[0034] The data acquisition module is used to collect the pressure, temperature and humidity in the landmark screen, and transmit the collected data to the controller; wherein, the atmospheric pressure in the pressure landmark screen.

[0035] The data acquisition module includes a pressure acquisition unit (pressure sensor), a temperature acquisition unit (temperature sensor), and a humidity acquisition unit (humidity sensor). The pressure acquisition unit is used to collect the atmospheric pressure in the landmark screen, the temperature acquisition unit is used to collect the temperature data in the landmark screen, and the humidity acquisition unit is used to collect the humidity data in the landmark screen.

[0036] The landmark screen is factory-evacuated with negative pressure. If the pressure is lost and the humidity (humidity monitoring) increases, it indicates that the landmark screen is leaking. The leakage fault is transmitted to the controller, and the controller controls the shutdown module to shut down the landmark screen. At the same time, the controller transmits information to the service platform, and the service platform determines the information and transmits it to the maintenance personnel's mobile terminal for maintenance. The temperature of the landmark screen is monitored. When the temperature value exceeds the set temperature, it is transmitted to the controller. The controller drives the sleep module to put the landmark screen into sleep mode. The pressure of the landmark screen is monitored. When tourists step on the landmark screen, the internal pressure of the screen will increase, and then be transmitted to the controller. The sound and light alarm will flash the landmark screen and sound prompts to remind passengers and station staff.

[0037] Voltage acquisition module:

[0038] The voltage acquisition module (voltage sensor) is used to collect the voltage in the landmark screen, and determine whether the power supply in the landmark screen is faulty based on the voltage, and transmit the judgment result to the controller. If the power supply is faulty, the fault information is transmitted to the service platform through the controller. The service platform determines the information and transmits it to the maintenance personnel's mobile terminal for maintenance.

[0039] Image acquisition module:

[0040] The image acquisition module is used to collect the original image and real-time image above the landmark screen through a fixed camera, and transmit the original image and real-time image to the calculation module for processing. The original image and the real-time image are both images of the same position, so a fixed camera is used, and the camera's shooting area is the warning area.

[0041] The image acquisition module starts to acquire images when the picture above the landmark screen changes, and stops acquiring images when the picture changes. When the picture changes, it indicates that someone may try to cross the cordon of the station, so image acquisition is performed.

[0042] The situation where the picture changes starts is: the original image and the real-time image are collected. When the collected real-time image does not completely overlap with the original image, that is, a change occurs, the image that starts to change is determined to be the first frame of the changed image; that is, when no one crosses the line, each frame of the image collected by the camera is exactly the same (original image). When a different image is collected (there is a change in the image), it can be determined that someone is trying to cross the cordon of the station.

[0043] The situation where the picture change ends is: when the real-time image after the changed image completely overlaps with the original image, it is determined that the previous frame of the real-time image is the last frame of the changed image; that is, after a person crosses the cordon, or tries to cross it but fails, each frame of the image captured by the camera is exactly the same (the same as the original image captured at the beginning), that is, the previous frame of the image is the last frame of the changed image.

[0044] The original image is collected, and the direction of the station warning line is determined according to the original image, and the starting edge warning line and the ending edge warning line are set according to the direction of the station warning line; wherein the starting edge warning line and the ending edge warning line are both the edges of the original image. The direction of the vehicle warning line indicates which side is the standing area for people and which side is the driving area (the area prohibited from entering), and based on this, the starting edge warning line and the ending edge warning line can be determined, and both are the edges of the image.

[0045] Compute module:

[0046] The calculation module is used to receive the real-time image, and calculate the changing picture frame when the picture changes, and the distance between the changing picture frame and the frame of the original image according to the original image and the real-time image.

[0047] The calculation module compares the changed image with the original image to determine the changed border of the changed image, and determines the point closest to the start edge warning line as the start point, and determines the point closest to the end edge warning line as the end point. When performing image comparison, the difference between the images can be determined, and the difference can be stroked to obtain the changed border of the image, and then the start point and the end point can be determined.

[0048] Cross-line determination module:

[0049] The line crossing determination module is used to determine whether a line crossing situation occurs according to the changing picture frame and the frame distance, and transmit the line crossing situation to the controller.

[0050] The specific determination method is:

[0051] S1. When the end point from the first frame of the changing image to the last frame of the changing image does not reach the end edge warning line, it is judged that the line has not been crossed; when the end point reaches the end edge warning line, it can be determined that the person has not crossed the line, or has stretched out his hands and feet and finally retracted them.

[0052] S2. When the end point from the first frame of the changing image to the last frame of the changing image reaches the end edge warning line, the distance from the starting point to the starting edge warning line is calculated; when the end point reaches the end edge warning line, someone may have crossed the warning line, and further judgment is required.

[0053] S3, when the distance from the starting point to the starting edge warning line is greater than zero, it is determined to be a line crossing; when the distance from the starting point to the starting edge warning line is equal to zero, the time length of the overlap between the ending point and the ending edge warning line is determined; wherein the time length is the time point of the last frame of the changing image minus the time point of the first frame of the changing image when the ending point and the ending edge warning line overlap;

[0054] S4, if the time length during which the end point overlaps with the end edge warning line is less than the set time length, it is determined that the line has not been crossed;

[0055] S5. If the time length during which the end point overlaps with the end edge warning line is greater than or equal to the set time length, it is determined to be a line crossing.

[0056] As in S3-S5 above, when the distance from the starting point to the starting edge warning line is greater than zero, it can be considered that the warning line has been crossed, so it is determined that the line has not been crossed. When the distance from the starting point to the starting edge warning line is equal to zero, there may be a hand-reaching behavior, but the warning line has not been crossed. Therefore, the length of time that the end point and the end edge warning line overlap is further determined. For example, the time for the person to reach out can be determined. When the time for the person to reach out is too long, dangerous behavior will also occur. Therefore, if the time exceeds the set time length, it is determined to be crossing the line, and an alarm and sound and light prompts are issued.

[0057] Sound and light alarm:

[0058] The sound and light alarm is connected to the controller; when the controller determines that a line crossing occurs, the sound and light alarm flashes the landmark screen and issues a voice reminder to passengers and station staff; wherein the line crossing situation is: when the controller determines that the pressure on the landmark screen increases, it is determined to be a line crossing; and the controller receives the line crossing information through the line crossing judgment module.

[0059] Hibernation module:

[0060] A sleep module is connected to the controller, and the controller receives the real-time temperature data of the landmark screen. When the real-time temperature data exceeds the set temperature, the controller transmits information to the sleep module to control the landmark screen to sleep.

[0061] Shutdown module:

[0062] A shutdown module is connected to the controller, and the controller receives real-time humidity data of the landmark screen. When the real-time humidity data exceeds the set humidity, it is determined that the landmark screen is leaking. The controller transmits information to the shutdown module to perform shutdown control on the landmark screen.

[0063] Service Platform:

[0064] A service platform and a mobile terminal, wherein the service platform is connected to the controller and the mobile terminal via WiFi or 5G, and the mobile terminal includes a mobile phone and a tablet computer; the service platform is used to receive power failure conditions transmitted by the controller, and when a power failure requires maintenance, the maintenance information is transmitted to the mobile terminal so that maintenance personnel can receive the information in time to maintain the landmark screen.

[0065] The present invention provides a data acquisition module for collecting pressure, temperature and humidity in the landmark screen. When these data exceed the set threshold, corresponding alarm, sleep or shutdown processing is performed. A voltage acquisition module is provided for collecting the voltage in the landmark screen, and thereby determining whether the power supply in the landmark screen is faulty; an image acquisition module is provided for collecting the original image and real-time image above the landmark screen, and thereby determining the changing picture border when the picture changes, and determining whether there is a line crossing according to the changing picture border, so as to alarm the personnel who cross the warning line, and simultaneously emit flashing light and sound for prompting, so as to comprehensively monitor the platform personnel and reduce the hidden dangers to driving safety.
