Description

Technical Field

[0001] The present application relates to the technical field of crowd flow monitoring, and in particular to a crowd congestion monitoring device. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, crowded public places such as shopping malls, stations, scenic spots, etc. are becoming more and more common. However, the problem of crowd congestion has also come along, bringing challenges to people's travel and public safety. In order to solve this problem, crowd congestion monitoring devices came into being.

[0003] Traditional crowd monitoring methods mainly rely on advanced sensor technology, image processing technology and data analysis technology to achieve real-time monitoring and early warning of crowd flow. Among them, sensor technology is one of the core technologies in crowd monitoring. By arranging various sensors in the monitoring area, such as infrared sensors, ultrasonic sensors, etc., the crowd flow in the area can be sensed in real time. At the same time, combined with image processing technology, such as computer vision technology, the crowd flow images captured by the camera can be analyzed and processed to achieve more accurate monitoring effects. In addition, data analysis technology is also an indispensable part of crowd congestion monitoring devices. By collecting a large amount of monitoring data and using data analysis technology to conduct in-depth analysis of the distribution, density, flow speed, etc. of crowd flow, future congestion trends can be predicted, providing decision-making basis for managers.

[0004] At present, the traditional crowd monitoring device, such as a feeder airport passenger flow monitoring device with the existing announcement number CN216679213U (China, the authorization announcement date is 2022-06-07), includes a crowd monitoring camera, a mounting plate is fixedly arranged on the upper end of the crowd monitoring camera, two hanging plates are fixedly arranged on the lower surface of one end of the mounting plate, a connecting plate is rotatably connected between the two hanging plates through a rotating shaft, a cleaning bin is fixedly connected to the other end of the connecting plate, a circular guide rail is fixedly connected to the upper end of the cleaning bin, and a No. 1 motor is also fixedly arranged on the lower surface of the mounting plate. By setting up this kind of automatic cleaning device, the surface of the crowd monitoring camera can be wiped and dusted even if it is installed at a higher position by controlling multiple motors to work, so as to avoid the dust on the surface of the crowd monitoring camera from staying and accumulating for a long time, thereby ensuring the accuracy of crowd monitoring, and the two-way motion annular cleaning structure of the technical solution can clean all surfaces of the crowd monitoring camera, and the effect is remarkable. However, the above scheme still has certain defects, and the inventor has found through research. Long-term use of the above device may cause aging of the camera or its related power components, thereby causing failures. What is even more difficult is that existing camera designs are often difficult to disassemble, and once a failure occurs, maintenance work will become complicated and time-consuming. This means that in practical applications, maintenance costs and efficiency have become an issue that cannot be ignored. Secondly, the above-mentioned crowd monitoring device may have blind spots in certain directions. This means that at certain angles or areas, the device cannot accurately monitor the flow of people, which undoubtedly weakens the comprehensiveness and accuracy of its monitoring.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0024] See also Figure 1 The present application provides a crowd congestion monitoring device, including a main structure 10 and an assembly structure 20.

[0025] The main structure 10 is used to monitor the flow of people, and the assembly structure 20 facilitates the quick disassembly of the camera.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 The main structure 10 includes a cross mounting plate 110, four people flow monitoring cameras 120 installed at the four ends of the bottom of the cross mounting plate 110, and a support column 130 fixed by bottom bolts. It also includes a fixing member 140 installed between the cross mounting plate 110 and the support column 130, and the fixing member 140 includes a hole 141, a threaded head 142 and a locking nut 143.

[0027] The design of the cross mounting plate 110 plays a supporting and fixing role, which is convenient for the staff to install four crowd monitoring cameras 120, and reinforcing ribs or protrusions can be added to the surface of the cross mounting plate 110 to increase its rigidity and anti-deformation ability.

[0028] Among them, the design of the crowd monitoring camera 120 monitors the crowd flow in all directions and reduces blind spots. The design of the four crowd monitoring cameras 120 installed at the bottom of the cross mounting plate 110 enables the four crowd monitoring cameras 120 to capture the crowd flow in the venue from four different angles. Compared with the traditional single camera, this multi-angle monitoring method can more comprehensively understand the distribution and flow of crowds, improve the accuracy and reliability of the data, and at the same time, due to the installation of four crowd monitoring cameras 120, the monitoring range is expanded to better cover the entire area.

[0029] Among them, the design of the support column 130 provides a stable supporting force for the cross mounting plate 110. The support column 130 can be used as a mounting platform for other accessories or equipment, such as sensors, signboards, etc., thereby expanding the function of the device; in addition, its surface can also be coated with reflective material to improve visibility at night or in low visibility environments.

[0030] Among them, the design of the fixing part 140 enables the cross mounting plate 110 to be accurately fixed on the support column 130. Through the cooperation of the hole 141, the threaded head 142 and the locking nut 143, fast and accurate installation and fixation can be achieved. At the same time, the cross mounting plate 110 can be easily disassembled and reinstalled when necessary, which is convenient for daily maintenance.

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The assembly structure 20 includes an assembly part 210 and a clamping part 220 installed between a cross mounting plate 110 and four pedestrian monitoring cameras 120, wherein the assembly part 210 includes four large through holes 211, four small through holes 212, four cylinders 213 and four cover plates 214; the clamping part 220 includes a plurality of plug-in slots 221, a plurality of plug-in blocks 222 and a plurality of gaskets 223.

[0032] Among them, the design of the assembly part 210 allows the crowd monitoring camera 120 to be quickly and accurately installed on the cross mounting plate 110 as needed. Through the design that the large through hole 211 and the small through hole 212 are interconnected, the cover plate 214 can allow the cylinder 213 to slide back and forth between the large through hole 211 and the small through hole 212 through the large through hole 211. The cylinder 213 slides from the large through hole 211 to the small through hole 212, which can make the bottom edge of the cover plate 214 fit with the surface of the cross mounting plate 110, ensuring the stability of the installation of the crowd monitoring camera 120 and making its disassembly and daily maintenance more convenient.

[0033] Among them, the design of the clamping fixture 220 ensures the precise fixation between the cover plate 214 and the cross mounting plate 110, the cooperation between the plug slot 221 and the plug block 222 enables the crowd monitoring camera 120 to remain stable under various environmental conditions, and the addition of the gasket 223 can increase the friction between the cover plate 214 and the cross mounting plate 110.

[0034] The working principle of the crowd congestion monitoring device is as follows: when monitoring crowd flow, the four crowd monitoring cameras 120 installed at the four ends of the bottom of the cross mounting plate 110 can capture the crowd flow in the venue from four different angles. When the cross mounting plate 110 needs to be disassembled, the cross mounting plate 110 can be removed from the threaded head 142 by unscrewing the locking nut 143. When the crowd monitoring camera 120 needs to be repaired, the staff pushes the crowd monitoring camera 120 upward to make the cover plate 214 and the plug-in block 222 disengage from the plug-in slot 221, and then slide the cylinder 213 from the small through hole 212 to the large through hole 211, so that the cover plate 214 can be taken out from the inside of the large through hole 211, and the crowd monitoring camera 120 can be quickly disassembled.

[0035] It should be noted that the specific models and specifications of the crowd monitoring camera 120, the cover plate 214, and the locking nut 143 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and principle of the crowd monitoring camera 120 are clear to those skilled in the art and will not be described in detail here.

[0037] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
