DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments: A smart bus stop sign for real-time passenger flow monitoring, see attached Figure 1 and attached Figure 2As shown, it includes a pedal box 1, which is a rectangular structure with a length greater than 2m and a width less than 0.8m. It is set at the bus stop boarding point. Two side baffle boxes 2 with the same length as the pedal box 1 are symmetrically set on the pedal box 1, and the height of the side baffle box 2 is less than 1.2m, so that a U-shaped space for accommodating a single row of passengers is formed between the pedal box 1 and the side baffle box 2, so that the passengers are arranged in a column in an orderly manner; a movable opening 21 is opened on the inner side of the side baffle box 2 near the front end, and the top surface of the side baffle box 2 is vertically set near the front end There is a vertical pipe 3, and the top of the two vertical pipes 3 is connected to a mounting shell 4. The distance between the mounting shell 4 and the pedal box 1 is not less than 2m, so that the mounting shell 4 has a sufficient height to avoid "passengers bumping into each other", and a mounting cavity 41 is provided in the mounting shell 4, and a strip-shaped opening 42 is provided on the surface; a bus information monitor 5 is also installed on the mounting shell 4 to monitor and display the bus schedule, departure and arrival information in real time. The bus information monitor 5 is a conventional technology in the prior art, and this application does not elaborate on this; in addition, the pedal box 1 is provided with a mounting cavity 41 in the mounting shell 4 and a strip-shaped opening 42 on the surface; a bus information monitor 5 is also installed on the mounting shell 4 to monitor and display the bus schedule, departure and arrival information in real time. The bus information monitor 5 is a conventional technology in the prior art, and this application does not elaborate on this; in addition, the bus information monitor 5 is provided in the pedal box 1. A driving component 6 is provided, one set of execution ends of the driving component 6 extends into the side baffle box 2 and is connected to the movable opening 21, and is connected to a counting component 7. In the initial state, the counting component 7 is more than 0.8m high from the stepping box 1, so that it acts as an "interceptor bar" in this state to prevent passengers from moving forward, and when the bus information monitor 5 detects that the bus is about to arrive at the station, the driving component 6 operates and moves the counting component 7 downward to contact the stepping box 1, so that the counting component 7 enters the counting state, and when the bus information monitor 5 detects that the bus leaves the station, the driving component 6 operates and moves the counting component 7 upward to reset, so that the counting component 7 enters the "interceptor bar" state; another set of execution ends of the driving component 6 extends into the installation cavity 41 and is connected to a linkage component 8, the execution end of the linkage component 8 is connected to the strip opening 42 and is connected to a cleaning component 9, the cleaning component 9 contacts the bus information monitor 5, and performs a cleaning action on the bus information monitor 5 with a downward movement of the counting component 7, and resets with an upward movement of the counting component 7, and completes a cleaning action again in the reverse direction during the reset process.

[0020] During the specific implementation of the present application, the bus information monitor 5 monitors the status of the bus in real time. When it detects that the bus is about to arrive at the station, it sends a signal to the driving component 6 in the pedal box 1. One set of execution ends of the driving component 6 drives the counting component 7 in the side block box 2 to move down and contact the pedal box 1, releasing the interception state, allowing passengers to pass into the boarding area, and the counting component 7 synchronously enters the counting state to record the number of people on the bus; at the same time, another set of execution ends of the driving component 6 drives the linkage component 8 in the installation cavity 41, so that the cleaning component 9 connected to the strip opening 42 performs the cleaning action on the bus information monitor 5; when the bus information monitor 5 detects that the bus leaves the station, the driving component 6 operates to make the counting component 7 move up and reset, and act as an "interception bar" again to prevent subsequent passengers from entering. The cleaning component 9 is also reset synchronously, waiting for the next time the counting component 7 moves down to perform the cleaning action again. The present application realizes the integrated functions of orderly queuing of passengers, passenger flow statistics and cleaning of the bus information monitor 5 through the linkage between the various components.

[0021] For the drive assembly 6 in the above solution, specifically, refer to the attached Figure 2 As shown, the drive assembly 6 includes a dual-output shaft reducer 61, which is installed in the pedal box 1, and the two output ends of the dual-output shaft reducer 61 are each connected to a rotating shaft 62, and a driving gear 63 is installed on the rotating shaft 62. The driving gear 63 is engaged with a passive gear 64, and the passive gear 64 is connected to a vertical threaded rod 65. The vertical threaded rod 65 is rotatably set in the pedal box 1 and passes through the side baffle box 2 and the vertical pipe 3 to connect to the installation cavity 41. The vertical threaded rod 65 is located on a section of the side baffle box 2 and is equipped with a slider 66. The slider 66 is slidably set in the side baffle box 2 and is connected to the movable port 21 and the counting assembly 7.

[0022] In the implementation process of the scheme, the double-output shaft speed reducer 61 is the power core, and two output ends of the double-output shaft speed reducer 61 are connected with rotating shafts 62 respectively. The rotating shafts 62 drive the driving gears 63 to rotate. The driving gears 63 are engaged with passive gears 64, and the rotation is transmitted to the vertical threaded rods 65. When the bus information monitor 5 monitors that the bus is about to stop, the double-output shaft speed reducer 61 starts, the driving gears 63 rotate, and drive the passive gears 64 and the vertical threaded rods 65 to rotate. In the side blocking box 2, the sliding blocks 66 cooperating with the vertical threaded rods 65 slide up and down along the vertical threaded rods 65 due to the threaded transmission principle. When the vertical threaded rods 65 rotate, the sliding blocks 66 move downward, push the counting assembly 7 to descend to contact the stepping box 1, so that the counting assembly 7 enters the counting state, allows passengers to pass and records the number of passengers. When the bus departs, the double-output shaft speed reducer 61 reverses, the sliding blocks 66 drive the counting assembly 7 to move upward and reset, and act as an “intercepting rod” to prevent passengers from advancing. At the same time, the vertical threaded rods 65 pass through the vertical pipes 3 and are connected to the installation cavities 41. The rotation of the vertical threaded rods 65 drives the linkage assembly 8 through mechanical linkage, and then drives the cleaning assembly 9 connected to the strip-shaped ports 42 to move transversely, so as to clean the bus information monitor 5. When the counting assembly 7 counts downward each time, the cleaning assembly 9 synchronously performs a cleaning action each time, and when the counting assembly 7 moves upward and resets, the cleaning assembly 9 also resets.

[0023] For the counting assembly 7 in the above scheme, specifically, referring to the accompanying drawings, Figure 3 As shown in the drawings, the counting assembly 7 includes an outer shell 71, the outer shell 71 is open at the top and is connected between the two sliding blocks 66. The outer shell 71 is provided with a pressure sensor 72 and a buffer spring 73 inside. The end of the buffer spring 73 is connected with a pressure receiving plate 74, the pressure receiving plate 74 is vertically slidably arranged in the outer shell 71. When the pressure sensor 72 detects that the pressure receiving plate 74 is pressed once and the pressure value reaches a set value, the number of passengers is recorded.

[0024] During the implementation of the scheme, the outer shell 71 of the counting component 7 is connected between the two sliders 66 in the side baffle box 2. When the bus information monitor 5 detects that the bus is about to arrive at the station, the driving component 6 operates to make the slider 66 drive the outer shell 71 to descend, and the counting component 7 releases the "interception bar" state, and the passengers can enter the stepping box 1 area; at this time, the passengers will step on the pressure plate 74 in the outer shell 71 during the journey. After the pressure plate 74 is pressurized, it overcomes the resistance of the buffer spring 73 and slides vertically downward along the outer shell 71; when the pressure on the pressure plate 74 reaches the threshold value preset by the pressure sensor 72, the pressure sensor 72 The pressure signal is converted into an electrical signal, the counting program is triggered, and the number of people is recorded once (of course, in the specific implementation process, the setting value of the pressure sensor 72 is precisely debugged, which can not only effectively distinguish the normal passenger pedaling pressure from environmental interference, but also ensure that the pedaling of passengers of different weights can be accurately identified, thereby achieving accurate counting of passing passengers, such as setting the set value to 30kg); after the bus leaves the station, the driving component 6 drives the counting component 7 to move up and reset, and continue to act as an "interceptor bar", waiting for the next counting task, and every other cycle can feed back the number of people in the cycle to the background system, so as to realize passenger flow statistics for the bus stop.

[0025] In addition, considering the accuracy of passenger flow statistics, please refer to the attached Figure 4 As shown, the counting assembly 7 further includes a camera 75 and an infrared sensor 76 , both of which are disposed at the bottom of the mounting shell 4 to monitor the number of passengers below in real time.

[0026] During the implementation of the solution, camera 75 uses computer vision technology to monitor the passengers below in real time, and uses target detection algorithms (such as YOLO, SSD) to identify the body contours and head features of passengers, distinguish individuals and count their numbers. At the same time, it combines tracking algorithms (such as DeepSORT) to track the trajectories of moving passengers to avoid repeated counting; combined with infrared sensor 76, it monitors the movement of passengers by emitting and receiving infrared signals. When a passenger enters the sensing area of ​​infrared sensor 76, the infrared signal will be blocked, and the signal strength received by the sensor will change, triggering counting, thus compensating for the recognition errors that may occur in camera 75 under complex lighting environments. identification error; in the specific implementation process, the data collected by the pressure sensor 72, camera 75 and infrared sensor 76 are integrated through the data fusion algorithm. For example, when the camera 75 recognizes that the passenger enters the area, and the infrared sensor 76 senses the signal change, and the pressure sensor 72 detects that the pressure value reaches the set value, the system will confirm a valid count, reducing the misjudgment caused by environmental interference (such as falling leaves, light reflection) of a single sensor, and greatly improving the accuracy and reliability of passenger flow statistics. In addition, the use of multimodal data can also cross-validate, providing more comprehensive and accurate data support for bus companies to analyze peak passenger flow periods, passenger flow patterns, etc.

[0027] For the linkage component 8 in the above solution, specifically, refer to the attached Figure 5 As shown, the linkage assembly 8 includes a transverse threaded rod 81 rotatably arranged in the installation cavity 41, and the end of the transverse threaded rod 81 is connected to a driven gear 82, and the driven gear 82 is engaged with a driving gear 83, and the driving gear 83 is connected to one of the vertical threaded rods 65, so that the vertical threaded rod 65 rotates to drive the transverse threaded rod 81 in linkage, and the transverse threaded rod 81 is equipped with a moving block 84, which is horizontally slidably arranged in the installation cavity 41 and is connected to the strip-shaped opening 42 and is connected to the cleaning assembly 9.

[0028] During the implementation of the scheme, when the bus information monitor 5 detects that the bus is about to arrive at the station, the dual-output shaft reducer 61 in the driving assembly 6 is started, driving the vertical threaded rod 65 to rotate. At this time, the driving gear 83 connected to the vertical threaded rod 65 rotates accordingly, and the driving gear 83 transmits power to the horizontal threaded rod 81 by meshing with the driven gear 82. When the horizontal threaded rod 81 rotates, the moving block 84 matched with it makes horizontal linear motion along the horizontal threaded rod 81 under the action of the thread transmission. When the moving block 84 moves, it will drive the connected cleaning assembly 9 to move synchronously. The cleaning assembly 9 slides horizontally and contacts the surface of the bus information monitor 5 to complete the wiping and cleaning action of the bus information monitor 5 display screen; when the bus leaves the station, the driving assembly 6 drives the vertical threaded rod 65 to rotate in the opposite direction, the driving gear 83 and the driven gear 82 drive the horizontal threaded rod 81 to reverse, and the moving block 84 drives the cleaning assembly 9 to reset and return to the initial position.

[0029] For the cleaning component 9 in the above solution, specifically, refer to the attached Figure 6 As shown, the cleaning assembly 9 includes a mounting rod 91 , which is vertically connected to the moving block 84 , and is provided with at least two scraping strips 92 made of rubber material for contacting the bus information monitor 5 .

[0030] During the implementation of the scheme, when the moving block 84 in the linkage component 8 slides, the mounting rod 91 will move laterally, thereby driving the scraper 92 to clean the surface of the bus information monitor 5; the scraper 92 can fit tightly to the surface of the bus information monitor 5, effectively removing impurities such as dust, water stains, and stains; at least two scraper strips 92 are provided to form multiple cleaning lines, enhance the cleaning effect, ensure that a larger area can be covered in one cleaning action, improve cleaning efficiency, and reduce cleaning blind spots; as the moving block 84 reciprocates on the horizontal threaded rod 81, the scraper strip 92 follows the mounting rod 91 to wipe back and forth on the surface of the bus information monitor 5, and each time the counting component 7 moves down to trigger the linkage component 8 to act, the cleaning component 9 completes a cleaning, ensuring that the bus information monitor 5 is always in a clear and visible state, providing passengers with accurate bus information.

[0031] In addition, considering the rainy and snowy weather, in order to prevent the cleaning component 9 from scraping the rain and snow on the surface of the bus information monitor 5 and then directly dropping it onto the heads of the passengers below, for this purpose, refer to the attached Figure 7 As shown, the cleaning component 9 also includes a water trough 93, which is arranged at the lower end of the surface of the bus information monitor 5, and both ends of the water trough 93 extend to the outside of the two side baffle boxes 2. A scraper block 94 is connected to the water trough 93, and the scraper block 94 is connected to the mounting rod 91 through a connecting rod 95, so that the scraper block 94 moves in the water trough 93 as the mounting rod 91 moves.

[0032] In the implementation process of the scheme, when the linkage assembly 8 drives the mounting rod 91 to move laterally, the scraper block 94 will move synchronously in the water guide groove 93 installed at the lower end of the surface of the bus information monitor 5, and the two ends of the water guide groove 93 extend to the outside of the side blocking box 2 to form a complete water flow guiding channel. During the movement of the scraper block 94 in the water guide groove 93, the rain and snow water scraped off by the cleaning assembly 9 is timely collected and pushed to the two ends of the water guide groove 93, so that the rain and snow water is discharged along the water guide groove 93 to the outside of the side blocking box 2, avoiding direct dripping on the heads of passengers below. Through the cooperation of the water guide groove 93 and the scraper block 94, a waterproof and flow guiding system in rainy and snowy weather is constructed, which not only guarantees the cleaning effect of the bus information monitor 5, but also fully considers the waiting experience of passengers, and improves the practicality and humanization degree of the application in complex weather environment.

[0033] For the above-mentioned scheme, from the service life of the device, for this purpose, referring to the drawings Figure 8 As shown in the drawings, the stepping box 1 is provided with a heater 11, and in this scheme, the stepping box 1, the side blocking box 2, the vertical pipe 3 and the mounting shell 4 are connected.

[0034] In the implementation process of the scheme, the heater 11 in the stepping box 1 continuously emits warm air flow by converting electrical energy into heat energy. Since the stepping box 1, the side blocking box 2, the vertical pipe 3 and the mounting shell 4 are connected to form a relatively closed air circulation channel, the hot air generated by the heater 11 can circulate in the entire structure along the channel to uniformly heat each component. In cold weather, the hot air can improve the ambient temperature of the electronic devices such as the bus information monitor 5, preventing problems such as performance degradation of electronic components, shortening of battery endurance and the like caused by low temperature. In rainy and snowy and humid environment, the heat emitted by the heater 11 can reduce the humidity of the internal air, avoiding faults such as short circuit and poor contact of circuit components due to dampness. It can also prevent rust and corrosion of metal parts, reduce the problem of structural strength reduction and mechanical jam caused by rust. Through the synergistic effect of the heater 11 and the connecting structure, a stable working environment is created for various components in the intelligent bus stop board, significantly improving the overall service life of the device.

[0035] For the above-mentioned scheme, considering that there is a situation of "queuing up at the wrong station and going to the wrong station" in the queuing process of passengers, but it is difficult to retreat, in order to protect the queuing order from being disturbed, for this purpose, referring to the drawings Figure 9 and the drawings Figure 10 As shown in the drawings, the side blocking box 2 is provided with an opening 22 near the movable port 21, the opening 22 is not connected to the inside of the blocking box, a single-way door 24 is rotatably connected to the opening 22 through a rotating seat 23, a torsion spring 25 is further connected between the rotating seat 23 and the single-way door 24, and the single-way door 24 abuts against a baffle 26 arranged at the opening 22, so that the single-way door 24 can only be opened outward.

[0036] During the implementation of the scheme, under normal queuing conditions, the one-way door 24, under the action of the torsion spring 25, tightly contacts the baffle 26 at the opening 22, remains closed, maintains the closed queuing space formed by the side baffle box 2, and ensures that passengers wait for the bus in an orderly manner in a single column, preventing queue jumping or congestion; when a passenger finds that he or she has "queued in the wrong queue or got on the wrong station" and needs to leave the queue, he or she can apply an outward thrust to the one-way door 24, which can push the one-way door 24 to rotate outward around the rotating seat 23 and open, forming a passage for passengers to leave. After the passenger leaves, under the action of the torsion spring 25, the one-way door 24 will quickly reset and close, restoring the closed state of the side baffle box 2, preventing other passengers from entering the queue in reverse through this door, and avoiding disruption of the order of the queue.

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention.
