Description

Technical Field

[0001] The present invention belongs to the technical field of image acquisition, and in particular is a driver and passenger information acquisition system based on a wireless communication network. Background Art

[0002] With the development of wireless communication network technology, passenger stations can realize the automation and intelligence of driver and passenger information collection through image acquisition and monitoring, improve data processing efficiency, and provide more accurate information support for public security management; through information collection, passenger stations can verify and authenticate passenger identities, strengthen supervision and security inspections on mobile personnel, and improve public security management effects; passenger stations can establish a passenger blacklist database through information collection, restrict and manage people with criminal records or bad behaviors, and improve the level of public security management from the source.

[0003] Before getting on or waiting for the bus, drivers and passengers need to go through information collection at the bus station. Currently, most bus stations still use cameras for facial recognition, and then pass through the security gate to check whether the passengers are carrying any illegal items. Finally, they are allowed to pass after the security personnel confirm their information. The process is very cumbersome and time-consuming. If there is a sharp increase in the number of people during holidays, it is easy to cause delays in the flow of people and affect the normal operation of the bus station. In addition, the brightness and direction of light during facial recognition have a great impact on the accuracy of facial recognition, and the quality of facial images may be affected in strong or weak light environments. Moreover, the recognition effect of the face will be different at different angles, rotations or postures. Different angles may make it difficult to extract facial features, prolong facial recognition time, and aggravate the impact on the normal operation of the bus station. Summary of the invention

Compared with measuring by touching the top of the person's head, it can avoid disrupting the hairstyle of the person, which causes the person to feel more uncomfortable with the touch; and the total weight of the parts on the slide plate 24 is light, which avoids oppression on the shoulders of the person and causing discomfort;

[0037] The number of camera assemblies 13 on each slide plate 24 is at least three, and the camera assembly 13 consists of camera 1 25, camera 2 26 and camera 3 27; camera 1 25 and camera 3 27 are respectively located at the two ends of the slide plate 24, and camera 1 25 is inclined toward the entrance 12 of the acquisition device 1, and camera 3 27 is inclined toward the center of the acquisition device 1; camera 2 26 is located in the middle part of the slide plate 24, and camera 2 26 is horizontally facing the center of the acquisition device 1; a light shield 28 is provided on the slide plate 24, and the camera assembly 13 is located in the light shield 28; the light shield 28 blocks light for the camera assembly 13, and a transparent plate 29 is provided near the shooting area of ​​the camera assembly 13 of the light shield 28; camera 1 25, camera 2 26 and camera 3 27 are all conventional camera components; the transparent plate 29 isolates the camera assembly 13 from the external environment, and the transparency of the transparent plate 29 will not affect the normal operation of camera 1 25, camera 2 26 and camera 3 27.

[0038] Specific work flow: When collecting information at the passenger station, mobile drivers and passengers need to pass through the door of the collection device 1 before getting on the bus; before the person steps onto the weighing plate 15, the No. 1 sensor 16 is in a state of being contacted and triggered by the weighing plate 15, and the collection device 1 controls the electric telescopic rod 21 to remain stationary; after the person steps onto the weighing plate 15, the person's weight is pressed on the weighing plate 15, driving the weighing plate 15 to descend along the groove 14 to trigger the weighing assembly 17, thereby achieving the purpose of weighing the person; the weighing plate 15 is away from the No. 1 sensor 16, and the No. 1 sensor 16 loses the contact effect and is in an untriggered state. The state is detected and a signal is sent to the collection device 1, the collection device 1 controls the electric telescopic rod 21 to work, the electric telescopic rod 21 drives the lifting plate 2 to descend, and the lifting plate 2 drives the detection rod 23 to descend; when a person passes through the collection device 1, the main body of the collection device 1 completes a preliminary detection of whether the person carries a large metal object, and the detection rod 23 completes the close-range detection of the person through one lifting, eliminating the need to arrange additional security personnel to hold the detection rod 23 to detect the whole body of the person, thereby improving the degree of automation, accelerating the speed of personnel information collection, and improving the efficiency of the personnel information collection system;

[0039] As the lifting plate 2 descends, it drives the slide plate 24 downward, and the slide plate 24 drives the camera assembly 13 downward. Before the camera assembly 13 descends, it is located on the top of the acquisition device 1 to collect long-distance video of the person; after the camera assembly 13 descends, the slide plate 24 contacts the person's shoulder and stays, and the lifting plate 2 moves away from the slide plate 24 and continues to descend to drive the detection rod 23 to detect the person's clothing, while the camera assembly 13 staying on the person's shoulder collects video at close range; by weighing weight, measuring shoulder height and face recognition photography, multiple channels are adopted to confirm the person's information, improve the accuracy of information collection, and thus improve the efficiency of the information collection system; and when the slide plate 24 briefly stays on the person's shoulder, on the one hand, it reduces the person's discomfort of touching sensitive parts of the body, and on the other hand, it reminds the person through contact to avoid moving around during the contact period of the slide plate 24 to affect face recognition;

[0040] When the lifting plate 2 descends to the top of the collection device 1 near the groove 14, the second sensor 22 contacts the collection device 1 to trigger and send a signal, and the collection device 1 drives the lifting plate 2 to rise and reset through the electric telescopic rod 21. The lifting plate 2 rises to the top and contacts the bottom of the slide plate 24 and drives it to rise and reset. The slide plate 24 drives the camera assembly 13 to rise and reset, and the personnel can complete the personnel information collection work through the collection device 1;

[0041] Furthermore, since the camera assembly 13 is composed of camera 1 25, camera 2 26 and camera 3 27; when the person walks towards the acquisition device 1, the camera assembly 13 is close to the top of the acquisition device 1, and the camera 1 25 is at a high position and obliquely downward to collect the person's appearance, clothing and face; when the person stands in the acquisition device 1, the camera assembly 13 is located at the shoulder of the acquisition device 1, the camera 2 26 collects and identifies the person's side face, and the camera 3 27 collects and identifies the person's front face at close range; by collecting the overall appearance of the person at a long distance, collecting the side face at close range and collecting the front face at close range, the face collection angle is increased, the face recognition accuracy is improved, thereby improving the recognition efficiency, and then improving the efficiency of the personnel information collection system;

[0042] Furthermore, by providing the light shield 28, during the acquisition process of the camera assembly 13, the camera assembly 13 acquires the image of the person through the transparent plate 29, and the light shield 28 blocks the light outside the shooting range of the camera assembly 13 from entering, thereby avoiding the situation in which the quality of the facial image is affected in a strong light or weak light environment, thereby further improving the accuracy of facial recognition; further, by providing the transparent plate 29, dust and impurities in the external environment are prevented from adhering to the lens in the camera assembly 13 and blocking the acquisition of the image, thereby improving the image acquisition quality and accelerating the accuracy of facial recognition; in addition, when installing the light shield 28, a fill light may be installed inside to ensure the quality of image acquisition.

[0043] Embodiment 2:

[0044] Based on the first embodiment, as shown in the accompanying drawings of the specification Figure 1-Figure 6 As shown, a guide block 3 with a right-angled triangle cross section is fixedly connected to the top of the collection device 1, and the inclined surface of the guide block 3 faces the slide plate 24; a slide groove 31 is provided on the inclined surface of the guide block 3, and a slide rod 32 is slidably connected in the slide groove 31, and the slide rod 32 moves on the inclined surface of the guide block 3 in a vertical state; the part of the slide rod 32 away from the guide block 3 contacts the transparent plate 29, and the bottom of the slide rod 32 contacts the slide plate 24; the contact part of the slide rod 32 with the guide block 3 and the slide plate 24 can be equipped with a ball to reduce the friction between the slide rod 32 and the guide block 3, and between the slide rod 32 and the slide plate 24, thereby improving the sliding smoothness of the slide rod 32 on the inclined surface of the guide block 3 and the slide plate 24; the inclined state of the inclined surface of the guide block 3 is from the entrance 12 of the collection device 1 to the exit 11 of the collection device 1, and the inclined state of the slide groove 31 is the same as above;

[0045] An air bag 33 is provided in the slide groove 31, and an air outlet nozzle is provided in the air bag 33; air blowing holes 34 are evenly provided on the slide bar 32, and the air bag 33 is connected to the air blowing holes 34 through the air outlet nozzle and the air pipe;

[0046] A liquid reservoir 35 is provided in the slide groove 31, and paint is stored in the liquid reservoir 35, and the paint is used to be applied on the transparent plate 29 to prevent scratches; the liquid reservoir 35 and the air bag 33 are located on the same side of the slide rod 32; a liquid inlet nozzle and a liquid discharge nozzle are provided in the liquid reservoir 35, and the liquid reservoir 35 is connected with the blowing hole 34 through the liquid discharge nozzle and the water pipe; the air bag 33 and the liquid reservoir 35 are both made of materials with high elastic properties; the paint is selected from the type of transparent anti-scratch coating material in the prior art; the liquid inlet nozzle and the liquid discharge nozzle in the liquid reservoir 35 are both of the type of guided circulation, and the liquid inlet nozzle draws suction into the liquid reservoir 35, and the liquid discharge nozzle discharges to the outside of the liquid reservoir 35.

[0047] Specific working process: the slide plate 24 drives the transparent plate 29 to rise and reset through the light shield 28, the top of the slide plate 24 contacts the slide bar 32 and squeezes the slide bar 32 toward the inclined surface of the guide block 3, the slide bar 32 maintains a vertical state and slides along the inclined surface of the guide block 3 to scrape the transparent plate 29, wipes off the dust on the transparent plate 29, keeps the transparent plate 29 clean, reduces the obstruction of dust on image acquisition, and improves the efficiency of face recognition; when the slide bar 32 slides toward the exit 11 of the acquisition device 1 in the slide slot 31, the slide bar 32 squeezes the air bag 33, and the air bag 33 exhausts air to the blowing hole 34 through the air outlet nozzle, and the blowing hole 34 exhausts the air The air is blown toward the transparent plate 29 near the exit 11 of the collection device 1 by the slide bar 32, so that before cleaning the transparent plate 29, the slide bar 32 first blows away the dust on the transparent plate 29 that is easy to clean, and cooperates with the slide bar 32 to clean the transparent plate 29, so as to maintain the cleanliness of the transparent plate 29; when the slide bar 32 slides toward the entrance 12 of the collection device 1 by the spring return, the slide bar 32 no longer squeezes the air bag 33, and the air bag 33 elastically recovers by sucking air through the air outlet nozzle, and the air blowing hole 34 draws air toward the transparent plate 29, so as to speed up the air flow rate around the transparent plate 29 and prevent dust from falling on the transparent plate 29;

[0048] By setting the liquid storage bag 35, the liquid storage bag 35 is squeezed while the slide bar 32 squeezes the air bag 33. After the liquid storage bag 35 is squeezed, the paint inside is sprayed into the blowing hole 34 through the liquid discharge nozzle and the water light. The blowing hole 34 sprays the paint on the transparent plate 29 and leaves it to stand, leaving enough time for the transparent plate 29 and the paint to combine, thereby improving the anti-scratch effect of the paint on the transparent plate 29. When the slide bar 32 is reset and the transparent plate 29 is scraped again, the slide bar 32 scrapes off the excess paint and spreads it evenly. Furthermore, when the paint is sprayed through the air hole 34, the air bag 33 also blows air into the air hole 34 to increase the spraying speed of the air hole 34, so that the air hole 34 can spray the paint onto the transparent plate 29 faster and farther, thereby avoiding insufficient spraying pressure of the paint and the failure to spray evenly onto the transparent plate 29, thereby improving the ease of use of the collection device 1; when the slide bar 32 is reset, the liquid storage capsule 35 absorbs air through the liquid inlet nozzle for elastic recovery, and the liquid storage capsule 35 is replenished through the liquid inlet nozzle after the paint is used up.

[0049] Embodiment three:

[0050] Based on the second embodiment, as shown in the accompanying drawings of the specification Figure 1-Figure 10 As shown, a sleeve 4 is sleeved on the slide bar 32, and sponge rings 41 are evenly arranged on the sleeve 4. The sponge rings 41 are vertically distributed on the slide bar 32, and the distance between the slide bar 32 and the transparent plate 29 is smaller than the radius of the sponge ring 41; annular grooves 42 are evenly opened on the sleeve 4, and the annular grooves 42 are located between adjacent sponge rings 41, and the blowing holes 34 are aligned with the annular grooves 42; a friction plate 43 is provided on the slide plate 24, and the surface of the sleeve 4 contacts the friction plate 43; the sponge ring 41 is made of a sponge material with high elasticity;

[0051] The slide bar 32 is provided with an arc-shaped piece 44, and the arc-shaped piece 44 is made of elastic material and is located in the sponge ring 41; there are multiple groups of arc-shaped pieces 44, and each group of arc-shaped pieces 44 is vertically distributed; there are two arc-shaped pieces 44 in each group, and the bending directions of each group of arc-shaped pieces 44 are opposite; one end of the arc-shaped piece 44 is fixedly connected to the slide bar 32, and the other end is connected to the outer edge of the sponge ring 41; the distance between the slide bar 32 and the transparent plate 29 is smaller than the length of the arc-shaped piece 44;

[0052] A cleaning plate 5 with an L-shaped cross section is provided on the slide bar 32, and the cleaning plate 5 is close to the center of the collection device 1; a first groove 51 is evenly provided on the side of the cleaning plate 5 close to the sponge ring 41, and the sponge ring 41 rotates through the first groove 51, and the inner wall of the first groove 51 contacts the outer ring of the sponge ring 41; scrapers are evenly provided in the first groove 51, and the scrapers are inclined;

[0053] A second groove 53 is evenly opened on one side of the cleaning plate 5, and the second groove 53 is located in the middle position inside the first groove 51; the cross-section of the second groove 53 is set in a shape with large openings at both ends and a small opening in the middle, and the opening of the second groove 53 close to the first groove 51 is larger than the opening in the middle of the second groove 53.

[0054] Specific working process: when the slide plate 24 rises to contact the bottom of the slide bar 32, the slide plate 24 drives the side of the friction plate 43 to contact the outer surface of the sleeve 4, and the slide bar 32 drives the sleeve 4 to move toward the outlet 11 of the acquisition device 1. Since the friction plate 43 is in close contact with the sleeve 4, the sleeve 4 rolls along the friction plate 43 to approach the outlet 11 of the acquisition device 1, and the blowing hole 34 blows air and paint toward the transparent plate 29 through the annular groove 42. The sleeve 4 drives the sponge ring 41 to rotate and approach the outlet 11 of the acquisition device 1, so that the sponge ring 41 rotates and wipes the transparent plate 29 during the movement. While wiping away dust, the sponge ring 41 will not scratch the transparent plate 29 due to multiple wiping, so as to maintain the transparency of the transparent plate 29 and improve the image acquisition quality;

[0055] When the sponge ring 41 wipes the dust, since the distance between the slide bar 32 and the transparent plate 29 is smaller than the radius of the sponge ring 41, the part of the sponge ring 41 close to the transparent plate 29 is deformed due to extrusion, thereby increasing the contact area between the sponge ring 41 and the transparent plate 29, improving the wiping area, and maintaining efficient wiping and cleaning capabilities; during the reset process of the slide bar 32, the sponge ring 41 wipes the transparent plate 29 stained with paint, absorbing excess paint while applying the paint more evenly;

[0056] In addition, the sleeve 4 drives the arc-shaped piece 44 to rotate and contact the transparent plate 29, and the end of the arc-shaped piece 41 indirectly contacts the transparent plate 29 through the sponge ring 41. Since the distance between the slide rod 32 and the transparent plate 29 is smaller than the length of the arc-shaped piece 44, the arc-shaped piece 44 is squeezed and bent, and two of each group of arc-shaped pieces 44 are bent to opposite places respectively, ensuring that the sponge ring 41 is in an upward and downward expansion posture when being squeezed and deformed, so that adjacent sponge rings 41 are squeezed and deformed to contact each other, so that the sponge ring 41 does not block the blowing hole 34 from blowing, and the plurality of sponge rings 41 can completely cover the transparent plate 29 through squeezing and deformation, so as to avoid the sponge ring 41 being squeezed and condensed together, but reduce the contact area between the sponge ring 41 and the transparent plate 29, thereby improving the stability of the sponge ring 41 during the squeezing and deformation process;

[0057] By setting the cleaning plate 5, when the sponge ring 41 approaches the exit 11 of the acquisition device 1, the sponge ring 41 wipes the dust and rotates to contact the first groove 51, the opening edge of the first groove 51 scrapes the sponge ring 41, and the scraper 52 inside the first groove 51 also scrapes the sponge ring 41 to clean the sponge ring 41, thereby improving the cleaning ability of the sponge ring 41 and avoiding the influence of impurities on the transparent plate 29 on image acquisition; when the sponge ring 41 approaches the entrance 12 of the acquisition device 1 to reset, the sponge ring 41 that absorbs excess paint passes through the first groove 51 and contacts the second groove 53, and as the sponge ring 41 rotates continuously to the middle part of the second groove 53 The sponge ring 41 is squeezed by the inclined inner walls on the upper and lower sides of the second groove 53, and the paint absorbed in the sponge ring 41 is squeezed out, thereby improving the continuous water absorption capacity of the sponge; and, the arc-shaped sheet 44 indirectly contacts the inner wall of the second groove 53 through the sponge ring 41, and the inclined inner wall of the second groove 53 squeezes each group of arc-shaped sheets 44, and the two arc-shaped sheets 44 squeeze the middle sponge ring 41 again, thereby reducing the residual paint in the sponge ring 41 and improving the continuous water absorption capacity of the sponge ring 41; after the sponge ring 41 and the arc-shaped sheet 44 rotate through the second groove 53, the arc-shaped sheet 44 and the sponge ring 41 elastically recover until they pass through the first groove 51 and move away from the cleaning plate 5.

[0058] Embodiment 4:

[0059] Based on the third embodiment, as shown in the accompanying drawings of the specification Figure 1-Figure 6As shown, a vertically arranged limit groove 6 is opened on one side of the guide block 3, and the limit groove 6 is slidably connected to a limit plate 61 close to the inner wall of the guide block 3, a spring is provided between the limit plate 61 and the limit groove 6, and the limit plate 61 slides toward the inside of the guide block 3; an electromagnet 62 is installed on the side of the limit groove 6 away from the guide block 3, and the electromagnet 62 is close to the limit plate 61; a limit block 63 is slidably connected in the limit groove 6, and a No. 3 sensor 64 is provided on the top of the limit block 63; the No. 3 sensor 64 is a conventional pressure sensor; and the electromagnet 62 is magnetically isolated from the equipment parts.

[0060] Specific working process: when the transparent plate 29 needs to be cleaned, the electromagnet 62 is in a power-off state, the limit plate 61 is affected by the spring to return to the inside of the guide block 3, the slide plate 24 rises to contact the slide bar 32, the slide bar 32 cleans the transparent plate 29, the slide plate 24 continues to rise and contacts the limit block 63 and drives the limit block 63 to rise along the limit groove 6, the limit block 63 rises and drives the third sensor 64 to contact the top inner wall of the limit groove 6, at this time the slide bar 32 moves to the end of the slide groove 31; the third sensor 64 sends a signal to the acquisition device 1 to control the slide plate 24 to descend, and after the slide bar 32 is reset to the beginning of the slide groove 31, the slide plate 24 is stationary;

[0061] When the transparent plate 29 does not need to be cleaned, the electromagnet 62 is energized to suck the limit plate 61 out of the guide block 3 and fix it in the limit groove 6. The spring on the limit plate 61 is compressed and is in a state of storing force. The slide plate 24 drives the No. 3 sensor 64 to rise and contact the bottom of the limit plate 61 through the limit block 63. The No. 3 sensor 64 is triggered, and the slide plate 24 descends a set distance and then remains stationary. In this way, the transparent plate 29 can be switched back and forth between the mode of needing to be cleaned and the mode of not needing to be cleaned, thereby avoiding cleaning the transparent plate 29 every time personnel information is collected, which increases the risk of scratching the transparent plate 29, thereby increasing the service life of the transparent plate 29 and further improving the practicality of the collection device 1.
