Description

Technical Field

[0001] The utility model relates to the technical field of exhibition halls, in particular to a device for counting the number of people viewing exhibits in an exhibition hall. Background Art

[0002] An exhibition hall is a public building used to display temporary exhibits. According to the content of the exhibition, it is divided into two categories: comprehensive exhibition halls and professional exhibition halls. Professional exhibition halls can be divided into different types of exhibition halls such as industry, agriculture, trade, transportation, science and technology, culture and art. During the exhibition of exhibits indoors in the exhibition hall, there will be many visitors in front of the exhibits. It is of great significance to count the number of visitors for each exhibit, which can facilitate the flow of people and commercial evaluation of the above scenes. For example, for scenes where the number of people entering needs to be controlled, when the number of visitors counted reaches a specified number, corresponding restrictive measures can be taken to control the flow of people.

[0003] In the related technology of counting the number of visitors through monitoring equipment, cameras are set in designated areas of relevant scenes, such as entrances and exits, and images of the designated areas are collected by the cameras. The images are analyzed by deep learning algorithms, and the number of visitors is increased by one every time a visitor is detected entering the designated area.

[0004] However, the above method is not suitable for counting the number of visitors in front of the exhibits. Most of the exhibition booths are in an open hall, and visitors can walk from all directions to the exhibits to view the exhibits. The method of using cameras to shoot and count the number of people in designated areas (such as entrances and exits) is not applicable to the current situation.

[0005] In the published Chinese patent application, publication number: CN110717358A, patent name: visitor number counting method, device, electronic device and storage medium, although the prior art compares the face image to be identified with the whitelist face images in the preset whitelist to determine whether there is a whitelist face image that matches the face image to be identified; if there is no whitelist face image that matches the face image to be identified, the face image to be identified is compared with the visitor face images in the visitor list to determine whether there is a visitor face image that matches the face image to be identified; if there is no visitor face image that matches the face image to be identified, the face image to be identified is used as a new visitor face image and added to the visitor list; the number of visitor face images in the visitor list is counted to obtain the number of visitors. However, the prior art uses a camera to perform face recognition to perform number counting. In the implementation process, the camera is fixedly installed at a certain entrance and exit to perform number counting by face recognition. This method of number counting is not suitable for counting the number of visitors in front of the exhibits.

[0006] In summary, in order to solve the problems existing in the prior art, this case is proposed to solve them. Utility Model Content

[0029] For example, see Figures 1 to 4 The utility model provides a technical solution: a device for counting the number of people viewing exhibits in an exhibition hall, which is used for counting the number of people viewing exhibits 7 indoors in the exhibition hall, including a control panel, a support frame 3, and a booth 4 for supporting the exhibits 7, the booth 4 being fixedly installed above the middle of the support frame 3, and a plurality of support plates 2 are arranged on the support frame 3 and around the booth 4, the upper surface areas of the support plates 2 are equal, and the support plates 2 are longitudinally slidably connected to the support frame 3.

[0030] The control board adopts one of an editable logic controller or a microprocessor, and the control board is equipped with software programs such as a logic control program and a timing control program to meet the control needs of the viewing number counting device of the entire exhibition hall exhibits 7. The overall height of the support frame 3 is about 20 centimeters. The support frame 3 is laid and installed on the floor 1 of the exhibition hall. Each support plate 2 is laid on the support frame 3 in a regular manner.

[0031] A support assembly is provided below each support plate 2, and the support assembly includes a first hydraulic cylinder 10 and a weighing sensor. The weighing sensor is provided at the output shaft end of the first hydraulic cylinder 10 and is used to detect the weight of the entire support plate 2. An infrared sensor is embedded on the upper part of each support plate 2; a plurality of cameras are provided on the exhibition stand 4, and each camera faces each support plate 2. The control board is electrically connected to each weighing sensor, each infrared sensor, and each camera through wires.

[0032] Each support plate 2 serves as a weighing platform. When a person stands on the support plate 2, the weighing sensor detects the weight of the support plate 2 and the person standing on it, and transmits the weight information to the control panel.

[0033] When a visitor stands on the support plate 2 for at least ten seconds, the weighing sensor weighs the weight of the support plate 2 and the human body on the support plate 2, and the weighing sensor 2 transmits the relevant weight data to the control panel. After receiving the weight data transmitted by all the weighing sensors, the control panel confirms that each non-repeated weight value is a person, and the number of people is the same as the number of weight values, thereby confirming the number of visitors A. Among them, staying for at least ten seconds is used to ensure the stability of the weighing result. The weighing accuracy is accurate to jin and liang to ensure that the body weight values ​​of two people are not the same.

[0034] Each infrared sensor is used to simultaneously detect whether there is someone on each support plate. When there is someone, the relevant data is transmitted to the control board, and the control board confirms the number of visitors B. The control board compares the number of visitors A with the number of visitors B, and finally confirms the number of visitors before exhibit 7, achieving the purpose of effectively counting the number of visitors before exhibit 7.

[0035] Each camera is used to count people using face recognition. The third headcount is performed using the camera. After the first two headcounts, a replacement headcount is performed to ensure the accuracy of the headcount. Although there are certain defects in the headcount using the camera, the combination of the three can effectively improve the accuracy of the headcount after the first two headcounts.
