Description

Technical Field

[0001] This utility model relates to the field of traffic flow monitoring technology, and in particular to a station passenger flow monitoring device. Background Technology

[0002] With the acceleration of urbanization and the expansion of rail transit networks, stations, as core transportation hubs, are experiencing a continuous increase in daily passenger flow. Accurate passenger flow monitoring has become crucial for ensuring operational safety and optimizing service efficiency. Existing station passenger flow monitoring devices have significant shortcomings in terms of structural adaptability and long-term stability. Regarding angle adjustment mechanisms, traditional devices mostly employ manual adjustment in a single dimension, making it difficult to meet the monitoring needs of multiple scenarios such as entrance gates, waiting corridors, and transfer passages. Furthermore, the complex environment of stations poses severe challenges to equipment maintenance. Suspended particulate matter, humid air, and pollutants such as dust and debris carried by passengers easily adhere to the surface of monitoring sensors (such as infrared detectors and camera lenses), significantly reducing monitoring accuracy.

[0003] Chinese Patent Publication No. CN219414085U discloses a smart pedestrian flow monitoring and shooting device, including a shooting body, a connecting rod installed below the shooting body, a slider installed at one end of the connecting rod, a fixing plate connected to the slider, and fixing bolts connecting the fixing plate to a wall. The fixing plate has a T-shaped limiting groove on the side near the slider, and the slider is slidably connected to the T-shaped limiting groove. This smart pedestrian flow monitoring and shooting device achieves its fixing purpose by inserting the slider downwards from above the T-shaped limiting groove. After connecting to an external power source, the shooting body can then be opened to take pictures.

[0004] However, the above-mentioned patent documents still have the following defects in practice;

[0005] Although the aforementioned patented device can monitor passenger flow, it lacks a mechanism to adjust the angle and range of the device during use, which easily creates blind spots and fails to cover more areas, thus reducing the efficiency of station-wide monitoring. Furthermore, dust, moisture, and debris carried by passengers (such as food scraps and paper scraps) in the station environment easily adhere to the lens surface, causing image blurring or infrared signal attenuation, resulting in the accumulation of pollutants that affects the accuracy of recognition.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1, as Figures 1 to 7 As shown, a station passenger flow monitoring device includes an installation plate 1. An adjustment mechanism 2 is fixedly connected to the lower end of the installation plate 1. An infrared camera 3 is fixedly connected to the lower end of the adjustment mechanism 2. An electric telescopic cylinder 4 is fixedly connected to the lower rear part of the infrared camera 3. A power storage mechanism 5 is fixedly connected to the front side of the lower middle part of the infrared camera 3. A spray pipe 6 is fixedly connected to the front end of the power storage mechanism 5.

[0028] In the specific implementation of this utility model, the entire device is first installed in a suitable position using the mounting plate 1. Then, the infrared camera 3 is manually swung to adjust its illumination angle under the action of the adjustment mechanism 2. After the entire device is installed, the infrared camera 3 is started to monitor the flow of people. During use, when it is necessary to rotate the infrared camera 3 to illuminate a wider area, the internal drive structure of the adjustment mechanism 2 is controlled to drive the infrared camera 3 after the angle has been adjusted to rotate, thereby enabling the infrared camera 3 to achieve a wider monitoring range. After the infrared camera 3 has been used for a long time, its lens surface will be contaminated with dust and other impurities from the station environment. Then, the electric telescopic cylinder 4 is activated to drive the internal structure of the power storage mechanism 5 to move. Under the operation of the internal structure of the power storage mechanism 5, a high-speed airflow is instantly released through the spray pipe 6 to spray dust onto the lens surface of the infrared camera 3, thereby removing loose particles such as dust and debris from the lens surface and achieving the purpose of cleaning.

[0029] Example 2: In order to achieve the purpose of adjusting the angle and rotation of the infrared camera, refer to... Figure 2 In this scheme, the adjustment mechanism 2 includes a slide rail 21, which is fixedly connected to the lower end of the mounting plate 1. A slide rail 22 is rotatably connected to the lower part of the slide rail 21. A motor 23 is fixedly connected to the upper wall of the inner cavity of the slide rail 21. A ball 24 is fixedly connected to the lower end of the slide rail 22. A movable block 25 is movably connected to the outer surface of the ball 24.

[0030] Furthermore, the output end of the motor 23 is fixedly connected to the middle of the inner cavity of the slide rail 22 via a coupling.

[0031] In the above, the connection between the ball 24 and the movable block 25 is coated with a friction and damping coating, which fixes the infrared camera 3 at the angle after swinging while swinging it.

[0032] In the above, the infrared camera 3 is directly swung to drive the movable block 25 to rub against the surface of the ball 24, thereby achieving the purpose of adjusting the angle. Then, after the entire device is installed, the motor 23 is started to drive the slide rail 22 to rotate at the lower end of the slide rail 21. The rotation of the slide rail 22 drives the ball 24 to rotate, which in turn drives the movable block 25 to rotate, thereby achieving the purpose of adjusting the angle of the infrared camera 3.

[0033] The specific installation method, circuit connection method, and control method of the motor 23 used above are all conventional designs, and will not be described in detail in this utility model.

[0034] Specifically, in order to achieve the purpose of cleaning the three lenses of the infrared camera, refer to Figures 3 to 6In this scheme, the power storage mechanism 5 includes a sealing cylinder 51, which is fixedly connected to the front side of the lower middle part of the infrared camera 3. Several springs 52 are fixedly connected in a ring array on the side of the rear wall of the inner cavity of the sealing cylinder 51 away from its axis. Several sealing cylinders 51 are fixedly connected to the front end of the same compression assembly 55. Inclined blocks 53 are fixedly connected to the upper and lower sides of the middle part of the rear wall of the inner cavity of the sealing cylinder 51. The output end of the electric telescopic cylinder 4 extends through the left side of the rear end of the sealing cylinder 51 to the outside and is fixedly connected to the locking block assembly 54. A square block 56 is slidably connected to the rear end of the compression assembly 55.

[0035] In the above process, by activating the electric telescopic cylinder 4, the locking block assembly 54 is moved forward within the sealing cylinder 51. When the internal structure of the locking block assembly 54 contacts the square block 56, it hooks onto the inner surface of the square block 56. Then, the electric telescopic cylinder 4 pulls the square block 56 backward, which in turn pulls the compression assembly 55 backward within the sealing cylinder 51. Simultaneously, the compression assembly 55 compresses the spring 52, putting it into a compressed state. Then, when the square block 56 is inside the sealing cylinder 51... When the cavity moves backward a certain distance, the square block 56 contacts the inclined block 53. Then, the inclined surface of the inclined block 53 squeezes the square block 56, causing the square block 56 to move to the right on the surface of the squeezing assembly 55. This causes the square block 56 to leave the internal structure of the locking assembly 54. Then, the elastic force of the spring 52 is released instantaneously, pushing the squeezing assembly 55 to move forward in the inner cavity of the sealing cylinder 51. This causes the squeezing assembly 55 to instantly push the air inside the sealing cylinder 51 to be sprayed from the spray pipe 6 to the lens of the infrared camera 3, so that the high-speed airflow generated can clean the lens.

[0036] Specifically, in order to hook onto square block 56 and pull it backward, refer to... Figure 5 In this solution, the locking block assembly 54 includes a fixing block 541, which is fixedly connected to the output end of the electric telescopic cylinder 4. A limit rod 542 is fixedly connected to the upper front right side of the fixing block 541. A toggle block 543 is rotatably connected to the upper left side of the fixing block 541. A torsion spring 544 is fixedly connected to the upper left side of the outer surface of the toggle block 543.

[0037] In the above process, when the fixed block 541 is pushed forward by the electric telescopic cylinder 4, the inclined surface of the lever 543 rotates with the surface structure of the square block 56. When the lever 543 passes the vertical part behind the square block 56, the lever 543 rotates back to its initial position under the action of the torsion spring 544, so that the lever 543 is on the inner surface of the square block 56. Then, the electric telescopic cylinder 4 pulls it backward, and at the same time, the rear end of the lever 543 hooks onto the inner surface of the square block 56 and moves backward. The limit rod 542 ensures that the lever 543 will not rotate forward, thereby achieving the purpose of driving the square block 56 to move backward.

[0038] Specifically, in order to achieve the goal of causing the extrusion component 55 to spring back when the square block 56 moves to the right, refer to... Figure 6 In this solution, the extrusion assembly 55 includes a slide plate 551, which is fixedly connected to the front end of several springs 52. A groove 552 is provided on the right side of the slide plate 551, and springs 553 are fixedly connected to the upper and lower sides of the right wall of the groove 552.

[0039] Furthermore, the front vertical portion of the square block 56 is slidably connected to the inner cavity of the groove 552, and the left ends of the two springs 553 are fixedly connected to the right end of the front vertical portion of the square block 56. The left side of the rear vertical portion of the square block 56 is arc-shaped.

[0040] In the above process, when the square block 56 moves backward a certain distance, the arc surface of the square block 56 contacts the inclined surface of the inclined block 53, and the square block 56 is gradually squeezed into the inner cavity of the groove 552 and moves to the right. At the same time, it falls off the surface of the paddle block 543, thereby releasing the elastic force of the compressed springs 52 instantly, pushing the slide 551 forward and quickly pushing the air.

[0041] It should be noted that the specific installation method, circuit connection method and control method of the electric telescopic cylinder 4 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
