Examination room video monitoring and mobile phone signal shielding system

Abstract

The invention discloses an examination room video monitoring and mobile phone signal shielding system, which comprises a video monitoring module, wherein the video monitoring module comprises a videosensor for acquiring video streams in a target position region and a central server; the video streams are transmitted to the central server through a network; the central server identifies the identity of an examinee according to seat arrangement of the examination room and stores the video streams to a cloud server; the central server runs an action recognition capturing program to carry out action capturing on the examinees in the examination room; the cloud server is provided with a video access interface for a third-party user terminal to obtain the video streams; an interference signal generation module comprises a cyclic scanning type full-frequency-band mobile phone signal interference circuit and an interference signal transmission antenna; the interference signal transmission antenna is arranged on the signal transmission end of the interference circuit; and the central server controls the interference running mode of the interference signal generation module. According to the system, targets of the examination room can be monitored accurately and effectively; the mobile phone signals are effectively shielded in full frequency band; and the system has the advantages of clear videos, strong mobile phone signal shielding effect and the like.

Description

technical field [0001] The invention relates to an examination room video monitoring and mobile phone signal shielding system. Background technique [0002] With the substantial improvement of the national education level, more and more people need to take various forms of examinations in the learning process. With the diversification of examinations and the increase in the number of candidates, the supervision of the examination room is obviously insufficient, resulting in cheating incidents in the examination room Repeatedly. Therefore, video monitoring and mobile phone signal shielding for single-table and single-person examination rooms are of great significance. [0003] The surveillance cameras used in the existing examination room are mainly arranged in the front corner of the examination room, which are far away from the examinee's desktop, and the angle is fixed, the imaging effect is poor, and it cannot clearly reflect the actions of each examinee. At the same ti...

Problems solved by technology

[0003] The surveillance cameras used in the existing examination room are mainly arranged in the front corner of the examination room, which is far away from the examinee's desktop, and the angle is fixed, the imaging effect is poor, and it cannot clearly reflect the actions of each examinee

At the same time, the effective shielding range of the existing mobile phone signal shielding device in the examination room is about 20 meters. At the edge of the shielding range, such as near the window of the examination room, the shielding effect of the traditional mobile phone signal shielding device is poor, and some mobile phones can still receive external signals.
