Description

Technical Field

[0001] This utility model relates to the field of people flow monitoring devices, and in particular to a people flow monitoring device for unmanned supermarkets. Background Technology

[0002] Unmanned supermarket customer flow monitoring devices are generally classified into infrared sensor type, video surveillance type, microwave radar type, and pressure sensor type.

[0003] Video surveillance-based pedestrian detection devices capture video footage from supermarket entrances and exits using cameras. Image recognition technology is then used to detect and track people in the video, thus calculating pedestrian flow. However, conventional video surveillance-based pedestrian detection devices are prone to missing detections in densely populated areas with high pedestrian traffic. Therefore, existing technologies typically incorporate partitions for pedestrian detection. These partitions are placed at equal intervals below the surveillance cameras at the supermarket entrance.

[0004] Dividing the entrance into multiple channels, with each channel allowing only one person to pass at a time, achieves the effect of evacuation and improves the accuracy of pedestrian flow identification. However, the partitions can significantly affect the rapid evacuation of people in emergencies; the presence of partitions can also easily affect the handling of large goods in the supermarket. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a pedestrian flow monitoring device for unmanned supermarkets, which solves the problem that the presence of fixed partitions in existing technologies affects the rapid evacuation of crowds.

[0006] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0007] A device for monitoring foot traffic in an unmanned supermarket includes a base plate, a gantry frame fixed to the top of the base plate, a camera fixed to the crossbeam of the gantry frame, and several partitions slidably disposed on the top surface of the base plate. The partitions slide along the length of the base plate on the top surface of the base plate and are positioned on the base plate by a limiting component.

[0008] Optionally, the top surface of the base plate is symmetrically provided with a sliding groove, and the bottom surface of the partition is fixed with a slider, which is slidably inserted into the sliding groove.

[0009] Optionally, the positioning component includes an n-shaped frame that is slidably connected to the inner wall of the partition through a sliding hole. The middle part of the n-shaped frame protrudes from the top surface of the partition. The top surface of the bottom plate is provided with a plurality of pairs of first slots spaced apart along the length of the bottom plate. When the position of the partition corresponds to a pair of first slots, the two ends of the n-shaped frame protrude from the bottom surface of the partition and are inserted into a pair of first slots.

[0010] Optionally, springs are fitted at both ends of the portion of the n-shaped frame that protrudes from the top surface of the partition. The upper end of the spring is fixed to the outer wall of the n-shaped frame, and the lower end of the spring is fixed to the top surface of the partition.

[0011] Optionally, the positioning component includes a plurality of second slots spaced apart along the length of the base plate on the top surface of the base plate, a cavity in the middle of the bottom surface of the partition, a flip plate rotatably connected to the partition near the cavity by a pivot pin, the flip plate extending into the cavity and forming a downwardly facing locking plate, a torsion spring sleeved on the outside of the pivot pin, one side of the torsion spring being fixed to the outer wall of the flip plate, and the other side of the torsion spring being fixed to the side wall of the partition, when the partition is facing the second slot, the locking plate is engaged in the second slot; a handle is fixed to the top of the partition, and an anti-slip sleeve is fixed to the middle of the handle.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The partition of this utility model is slidably connected to the base plate by setting a slider, which can realize the rapid sliding of the partition. In the event of a disaster, all partitions can be slid to the side of the passage to provide an unobstructed passage for emergency evacuation. The sliding partition can temporarily expand the width of the exit passage, solve the problem of fixed partitions restricting the handling of large goods, and improve the supermarket's operational efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, please refer to Figures 1 to 3 This embodiment provides a device for monitoring the flow of people in an unmanned supermarket, including a base plate 1, a gantry frame 2 fixed on the top of the base plate 1, a camera 3 fixed on the crossbeam of the gantry frame 2, a plurality of partitions 4 slidably arranged on the top surface of the base plate 1, the partitions 4 sliding along the length of the base plate 1 on the top surface of the base plate 1, a sliding groove 5 symmetrically opened on the top surface of the base plate 1, a slider 6 fixed on the bottom surface of the partitions 4, the slider 6 slidably inserted into the sliding groove 5, and the partitions 4 being positioned on the base plate 1 by a limiting component.

[0022] An n-shaped frame 7 is slidably connected to the inner wall of the partition 4 through a sliding hole. The middle part of the n-shaped frame 7 protrudes from the top surface of the partition 4. Springs 9 are sleeved on both ends of the part of the n-shaped frame 7 that protrudes from the top surface of the partition 4. The upper end of the spring 9 is fixed to the outer wall of the n-shaped frame 7, and the lower end of the spring 9 is fixed to the top surface of the partition 4. Several pairs of first slots 8 are spaced apart along the length of the bottom plate 1. When the position of the partition 4 corresponds to a pair of first slots 8, the two ends of the n-shaped frame 7 protrude from the bottom surface of the partition 4 and are inserted into a pair of first slots 8.

[0023] In the initial state, the partitions 4 are spaced apart on the top surface of the base plate 1. When it is necessary to expand the passage space, the upper end of the n-shaped frame 7 is lifted, and the spring 9 is stretched accordingly. At the same time, the lower end of the n-shaped frame 7 moves away from the first slot 8. When the lower end of the n-shaped frame 7 is disengaged from the first slot 8, the partition 4 can be pushed so that the slider 6 at its bottom moves in the slide groove 5, thereby completing the movement of the partition 4. When the n-shaped frame 7 moves above the pair of first slots 8, the n-shaped frame 7 is released, and the spring 9 rebounds to lock the lower end of the n-shaped frame 7 into the first slot 8. In this way, the partitions 4 can be moved to one side of the gantry frame 2 in sequence.

[0024] Example 2, please refer to Figures 4 to 5 The difference between this embodiment and embodiment one is that a plurality of second slots 10 are spaced apart along the length of the bottom plate 1 on the top surface of the bottom plate 1, a cavity is opened in the middle of the bottom surface of the partition plate 4, and a flip plate 11 is rotatably connected to the partition plate 4 near the cavity by a pivot pin. The flip plate 11 extends to the inside of the cavity and forms a downward-facing locking plate. A torsion spring 13 is sleeved on the outside of the pivot pin. One side of the torsion spring 13 is fixed to the outer wall of the flip plate 11, and the other side of the torsion spring 13 is fixed to the side wall of the partition plate 4. When the partition plate 4 is facing the second slot 10, the locking plate is engaged in the second slot 10. A handle 14 is fixed to the top of the partition plate 4, and an anti-slip sleeve 12 is fixed to the middle of the handle 14.

[0025] In the initial state, the partitions 4 are spaced apart on the top surface of the base plate 1. When it is necessary to expand the passage space, step on the part of the flip plate 11 that protrudes from the cavity of the partition 4, causing the flip plate 11 to flip. The torsion spring 13 also twists accordingly, causing the part of the flip plate 11 that is in the second slot 10 to leave the second slot 10. At this time, the partition 4 can be moved. When the partition 4 is moved to the second slot 10 on the side of the gantry frame 2, the torsion spring 13 rebounds and locks the lower end of the flip plate 11 into the second slot 10. In this way, all the partitions 4 can be moved to one side of the gantry frame 2 in sequence.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
