Description

Technical Field

[0001] The present invention relates to the technical field of train guidance systems, and in particular to an intelligent platform guidance method and system. Background Art

[0002] Under the current railway operation and management model, passengers need to enter the platform in advance to wait for the train to arrive. After entering the platform, passengers begin to look for the train stop door corresponding to their carriage. Since the same platform location corresponds to different stop door positions for different trains, multiple waiting signs will be set on the ground near the train side of the platform. Multiple waiting signs display different door positions in different colors. Passengers need to find their own door positions according to the corresponding colors prompted on the platform display screen, which is very inconvenient and easy to queue up in the wrong line.

[0003] Moreover, if there are too many people on the platform and a long queue forms behind the waiting sign, passengers who arrive late will not be able to see the waiting sign and will gather in the front, causing congestion and even safety accidents.

[0004] In order to improve the passenger guidance and safety management of high-speed railway platforms, we proposed an innovative platform guidance system solution. Summary of the invention

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides an intelligent platform guiding method.

[0006] The technical solution of the present invention is as follows: An intelligent platform guidance method, comprising: S1. Obtain the information of the next train that will stop at the target platform, including the train number, estimated arrival time and stop door position; S2. At time T1 before the estimated arrival time, turn on and adjust the ultraviolet spotlight to illuminate the fluorescent marker on the ground screen; According to the preset fluorescent powder mark position information of the ground target area corresponding to different train stop door positions, the ultraviolet spotlight position adjustment system is controlled to adjust the position and irradiation angle of the ultraviolet spotlight installed on the top of the platform column, so that the center position of the ultraviolet spotlight beam irradiates the center position of the fluorescent powder mark at the corresponding position on the platform ground screen; The fluorescent powder marker position information of the ground target area corresponding to the different stop door positions of the train includes the coordinate information and length information of the corresponding fluorescent powder marker in the ground target area of ​​the different stop door positions of the train; S3, adjusting the width of the ultraviolet spotlight beam outlet according to the ground fluorescent powder mark length information corresponding to the arriving train and the ultraviolet spotlight position information; S4. During the train stop, the platform ambient light intensity is obtained in real time, the irradiation angle between the ultraviolet spotlight and the platform ground is calculated, the angle position of the ultraviolet spotlight is dynamically adjusted, and the adjusted angle position information is obtained, and the last angle position information is stored as the memory angle information; S5. After the current train leaves, turn off the ultraviolet spotlight.

[0007] Wherein, the ultraviolet spotlight position adjustment system comprises: A height adjustment module is used to adjust the height of the UV spotlight on the column; A horizontal rotation module is used to adjust the horizontal rotation angle of the ultraviolet spotlight on the column; The vertical rotation module is used to adjust the vertical rotation angle of the ultraviolet spotlight on the column.

[0008] The control system for adjusting the position of the ultraviolet spotlight adjusts the position and irradiation angle of the ultraviolet spotlight installed on the top of the platform column, including: Obtain the memory angle information of the train number, and control the height adjustment module, the horizontal rotation module, and the vertical rotation module to adjust the ultraviolet spotlight to the memory angle position; Storing new memory angle information will automatically overwrite the old memory angle information.

[0009] In step S3, a shading plate is provided at the beam exit position of the ultraviolet spotlight, a beam exit hole with adjustable width is provided in front of the shading plate, and a filter is provided in front of the beam exit hole, which only allows ultraviolet light of 365nm to pass through.

[0010] A ground screen is arranged between two adjacent upright posts of the platform, wherein one or more sections of fluorescent powder markings are contained therein, and the fluorescent powder markings include a fluorescent powder layer at a lower portion and a transparent floor paint at an upper portion.

[0011] As a preferred embodiment, the ultraviolet spotlights are integrated with multiple ones, each with different intensities, and the phosphor layer includes multiple layers of fluorescent coatings, each layer of which can emit light of different colors under ultraviolet irradiation of different intensities, forming a multi-color display.

[0012] The present invention also includes an early warning system, comprising: Get the light intensity sensor information on the ground screen. If the light intensity is lower than 300, a maintenance alarm is triggered. Obtain wear sensor information from the floor screen. If the wear level exceeds 700, a maintenance alarm is triggered. Get the temperature sensor information in the platform. If the temperature is higher than 35℃, trigger a high temperature warning. Get the humidity sensor information in the platform. If the humidity is higher than 80%, the anti-slip warning is triggered.

[0013] It also includes an emergency response system, in which indicator arrows and emergency evacuation information are integrated in the ground screen. When an emergency occurs on the platform, the ultraviolet spotlight position adjustment system adjusts the ultraviolet spotlight to illuminate the indicator arrows and emergency evacuation information.

[0014] It also includes adjusting the intensity of the ultraviolet spotlights according to the flow of people at each stop gate on the platform, specifically: A1. At every T2 time interval, obtain the area image of each stop gate position on the platform, and divide the area image into a front row image and a back row image according to a preset proportional line, wherein the front row image is the area image close to the ground screen, and the back row image is the area image far from the ground screen; A2. Obtain the entire area image of each parking gate within a period T0, where T0=n*T2, and n is a natural number greater than 4; A3. For each parking door, execute the following steps simultaneously: Extract the faces in each area image of the current parking door position to form an area image face data set, and form the area image face data set of this period T0 into a periodic area image face data set. Perform comparative analysis on the periodic area image face data sets and count the number of times the same face appears. If the same face appears more than n / 2 times, put the face into the operation set; Count the number of faces in the operation set P1; The total number of times P2 that the face in the operation set appears in the front row images of all regional images in the TO cycle; A4. If P2>m*P1, where m is the warning factor, increase the power of the ultraviolet spotlight by one level; A5, continue to obtain the whole area image within the next cycle T0, and execute step A3; If P2>m*P1, m is the warning factor, then reduce the power of the second-level ultraviolet spotlight; A6, continue to obtain the whole area image within the next cycle T0, and execute step A3; If P2>m*P1, m is the warning factor, notify the platform staff.

[0015] The present invention also provides an intelligent platform guidance system, which adopts the above intelligent platform guidance method and comprises: The ground screen module is located between adjacent columns of the platform and has a fluorescent marker inside; The train information acquisition module obtains the train number, estimated arrival time and stop gate information of the train that is about to arrive at the station; The ultraviolet spotlight position adjustment module obtains the memory angle information of the train number and controls the ultraviolet spotlight position adjustment system to adjust the position and irradiation angle of the ultraviolet spotlight installed on the top of the platform column, so that the ultraviolet spotlight can illuminate the fluorescent powder mark in the platform ground screen.

[0020] In the attached picture: Figure 1 This is a schematic diagram of the ultraviolet spotlight position adjustment module; Figure 2 This is a state diagram of the fluorescent powder marking inside the platform ground screen illuminated by ultraviolet light; DETAILED DESCRIPTION

[0021] An intelligent platform guidance method, comprising: S1. Connect with the railway travel service system to obtain the information of the next train that will stop at the target platform, including the train number, estimated arrival time and stop gate position; S2. At a time T1 before the estimated arrival time, for example, 5 minutes before arrival, turn on and adjust the ultraviolet spotlight to illuminate the fluorescent marker on the ground screen. Specifically: According to the preset fluorescent powder mark position information of the ground target area corresponding to different train stop door positions, the ultraviolet spotlight position adjustment system is controlled to adjust the position and irradiation angle of the ultraviolet spotlight installed on the top of the platform column, so that the center position of the ultraviolet spotlight beam irradiates the center position of the fluorescent powder mark at the corresponding position on the platform ground screen; Among them, the ultraviolet spotlights are installed on the top of the platform columns; The fluorescent powder marking position information of the ground target area corresponding to the different stop door positions of the train includes the coordinate information and length information of the corresponding fluorescent powder marking in the ground target area of ​​the different stop door positions of the train; The UV spotlight position adjustment system includes: A height adjustment module is used to adjust the height of the UV spotlight on the column; Specifically, a vertical sliding device can be arranged on the platform column to adjust the height of the ultraviolet spotlight.

[0022] A horizontal rotation module is used to adjust the horizontal rotation angle of the ultraviolet spotlight on the column; The vertical rotation module is used to adjust the vertical rotation angle of the ultraviolet spotlight on the column.

[0023] It can be controlled by a dual stepper motor system, one for the X-axis (horizontally adjust the rotation direction) and one for the Y-axis (vertically adjust the rotation direction). The horizontal and vertical angles of the UV spotlight can be adjusted at the same time, improving the flexibility and response speed of the system.

[0024] Control the UV spotlight position adjustment system to adjust the position and irradiation angle of the UV spotlight installed on the top of the platform column, including: The memory angle information of the train is obtained, and the height adjustment module, the horizontal rotation module and the vertical rotation module are controlled to adjust the ultraviolet spotlight to the memory angle position.

[0025] By setting up an angle memory module to record the changes in illumination angle for each train due to seasonal or weather changes, the system can directly call the stored data during the next operation, reducing calculation time.

[0026] As a preferred solution, a self-correction module can be further provided, and an angle sensor and a limit switch can be provided in the ultraviolet spotlight position adjustment system. The limit switch can be designed to be fixed at the extreme position of the motor rotation angle to prevent the rotation from exceeding the mechanical boundary. Through the coordinated action of the angle sensor and the limit switch, the spotlight angle can be ensured to be always in the optimal state, thus overcoming the errors caused by mechanical wear.

[0027] In this embodiment, a ground screen is set between two adjacent pillars of the platform, which contains one or more sections of fluorescent powder logos. When there are fewer trains stopping at the platform, they can be arranged in a row. If there are more trains stopping at the platform, multiple rows can be set.

[0028] The fluorescent powder sign consists of a fluorescent powder layer at the bottom and a transparent floor paint at the top, which has two major characteristics: (1) Transparent state: In the absence of ultraviolet light, the fluorescent powder is in a transparent state and does not affect the normal visual effect of the ground. Only when the ultraviolet light is irradiated, the fluorescent powder will emit bright visible light and display the preset identification information.

[0029] (2) Wear-resistant protection: A layer of transparent floor paint is placed on top of the fluorescent powder layer. This layer of floor paint can not only effectively prevent the fluorescent powder from being worn out due to long-term trampling, but also has waterproof, dustproof and anti-slip functions, ensuring the long-term use of fluorescent signs in various weather conditions.

[0030] As a preferred embodiment, multiple ultraviolet spotlights are integrated, each with different intensities. The intensity of the ultraviolet spotlights is controlled by PWM. The phosphor layer includes multiple layers of fluorescent coatings. The multiple layers of fluorescent coatings are superimposed, each layer has a different response wavelength, and each layer of coating can emit different colors of light under different intensities of ultraviolet light to form a multi-color display. By adjusting the intensity of ultraviolet light, different colors and patterns can be displayed on the same floor. A light intensity sensor is set in the floor screen to monitor the brightness of the fluorescent coating in real time.

[0031] S3, adjusting the width of the ultraviolet spotlight beam outlet according to the length information of the ground fluorescent powder mark of the current train and the ultraviolet spotlight position information, and then turning on the ultraviolet spotlight; A shading plate is provided at the exit of the UV spotlight beam, see Figure 1 As shown, the front of the shading plate is provided with an adjustable beam exit hole. By adjusting the width of the beam exit hole, the ultraviolet beam can be focused into a narrow beam, irradiating only the position where information needs to be displayed, preventing the wide beam of the ultraviolet lamp from irradiating and causing all fluorescent signs to light up at the same time. Figure 2 As shown, the ground screen only displays part of the phosphor identification information.

[0032] A filter is placed in front of the beam exit hole, which only allows 365nm ultraviolet light to pass through. This wavelength belongs to long-wave ultraviolet (UVA), which can effectively excite the phosphor to emit light and is invisible to passengers, thus avoiding any visual interference while still effectively exciting the phosphor.

[0033] S4. During the train stop, the platform ambient light intensity is obtained in real time, the irradiation angle between the ultraviolet spotlight and the platform ground is calculated, the angle position of the ultraviolet spotlight is dynamically adjusted, and the adjusted angle position information is obtained. The last angle position information is stored as memory angle information. Storing new memory angle information will automatically overwrite the old memory angle information.

[0034] The present invention also includes an early warning system, which uses embedded sensors to detect the working status of the ground screen in real time, thereby realizing automatic detection and maintenance to ensure the long-term stable operation of the ground screen, specifically including: Get the light intensity sensor information in the ground screen. The light intensity sensor is used to detect the brightness of the ground fluorescent coating to ensure that the coating emits light normally and the brightness remains within the set range. If the light intensity is lower than 300, a maintenance alarm is triggered. Obtain the wear sensor information in the floor screen. The wear sensor is used to detect the physical wear degree of the floor screen and ensure that a maintenance alarm is issued when the coating wear exceeds the preset threshold. Specifically, if the wear degree exceeds 700, a maintenance alarm is triggered; Preferably, when it is detected that the floor screen is less worn, that is, less than 700, the coating may be slightly worn, so the power of the ultraviolet lamp is controlled to be increased, and the service life of the fluorescent coating is extended by increasing the irradiation intensity of the ultraviolet lamp to avoid immediate replacement or repair of the coating.

[0035] Get the temperature sensor information in the platform. If the temperature is higher than 35℃, trigger a high temperature warning. Get the humidity sensor information in the platform. If the humidity is higher than 80%, the anti-slip warning is triggered.

[0036] The temperature and humidity sensor is used to detect the environmental conditions around the ground screen to ensure that the temperature and humidity are suitable for the long-term stable operation of the fluorescent coating and prevent the harsh environment from affecting the life of the coating.

[0037] The present invention also includes an emergency response system, in which an indication arrow and emergency evacuation information are integrated in the ground screen. When an emergency occurs at the platform, the ultraviolet spotlight position adjustment system adjusts the ultraviolet spotlight to irradiate the indication arrow and emergency evacuation information.

[0038] Preferably, the indicator arrows and emergency evacuation information are arranged on both sides of the ground screen, where there will be no crowd blocking, which neither affects the display of the fluorescent powder identification information nor is it difficult for passengers to find it.

[0039] S5. After the current train leaves, turn off the ultraviolet spotlight.

[0040] As another implementation method, in order to better avoid the safety management problems caused by passengers crowding in front to check the ground signs when queuing, it also includes adjusting the intensity of the ultraviolet spotlight according to the flow of people at each stop gate of the platform to avoid the problem that the queuing passengers cannot see the fluorescent powder signs on the ground clearly due to the ultraviolet spotlight being too bright, too dark or malfunctioning, and constantly crowding in front. Specifically: A1. At every T2 interval, obtain the area image of each stop gate position on the platform, and divide the area image into front row image and back row image according to the preset proportion line. The front row image is the area image close to the ground screen, and the back row image is the area image far from the ground screen. The T2 time is based on the time it takes for passengers to pass through two adjacent stop gates to determine whether the passenger will pass through this stop gate or wait here.

[0041] A2. Obtain the entire area image of each parking gate within a period T0, where T0=n*T2, and n is a natural number greater than 4; For example, multiple area images of the current parking door position are obtained within 1 minute.

[0042] A3. For each parking door, execute the following steps simultaneously: Extract the faces in each area image of the current parking door position to form an area image face data set, and form the area image face data set of this period T0 into a periodic area image face data set. Perform comparative analysis on the periodic area image face data sets and count the number of times the same face appears. If the number of times the same face appears is greater than n / 2, the face is put into the operation set, and the people in the operation set are determined to be the passengers waiting for the bus at this stop door.

[0043] Count the number of faces in the operation set P1; The total number of times P2 that the face in the operation set appears in the front row images of all regional images in the TO cycle; If the fluorescent logo on the ground screen is displayed normally, passengers will queue up in order when they see it from a distance. If they cannot see it clearly, they will go to the front row to check and judge whether the ultraviolet spotlight at the current parking door is working properly based on the numerical relationship between P2 and P1.

[0044] A4. If P2>m*P1, where m is the warning factor, increase the power of the ultraviolet spotlight by one level; Based on the rule that the brightness of ultraviolet spotlights gradually decreases after long-term use, we first increase the power of ultraviolet spotlights to confirm whether it can solve the problem of passengers crowding forward.

[0045] A5, continue to obtain the whole area image within the next cycle T0, and execute step A3; If P2>m*P1, m is the warning factor, then reduce the power of the second-level ultraviolet spotlight; If increasing the power of the ultraviolet spotlights cannot solve the problem of congestion in the front row, and considering that the brightness of the ultraviolet spotlights is too high, the power of the ultraviolet spotlights at the second gear should be reduced so that the brightness of the ultraviolet spotlights drops to a level lower than before.

[0046] A6, continue to obtain the whole area image within the next cycle T0, and execute step A3; If P2>m*P1, m is the warning factor, notify the platform staff.

[0047] If reducing the power of the ultraviolet spotlights still does not solve the problem of congestion in the front row, consider that there is a malfunction and notify the platform staff to come and solve it.

[0048] Through this intelligent self-adjustment method, no manual on-site maintenance is required, saving labor costs.

[0049] The present invention also provides an intelligent platform guidance system, which adopts the above intelligent platform guidance method and comprises: The ground screen module is located between adjacent columns of the platform and has a fluorescent marker inside; The train information acquisition module obtains the train number, estimated arrival time and stop gate information of the train that is about to arrive at the station; The ultraviolet spotlight position adjustment module obtains the memory angle information of the train number and controls the ultraviolet spotlight position adjustment system to adjust the position and irradiation angle of the ultraviolet spotlight installed on the top of the platform column, so that the ultraviolet spotlight can illuminate the fluorescent powder mark in the platform ground screen.
