Embodiment 1
[0026] Such as Figure 1-3 As shown, the examination room anti-cheating monitoring system according to the embodiment of the present invention includes a smart wearable device 1, a camera module 2, a positioning module 3 and a monitoring module 4. 5 is connected with the positioning module 3 and the monitoring module 4, wherein the smart wearable device 1 includes a smart bracelet 6, an information entry module 7, an identity verification module 8, a basic information matching module 9, and a student information unit 10 , heart rate detection module 11 and data comparison unit 12;
[0027] Wherein, the camera module 2 includes a dome camera 13 connected in sequence, an omni-directional rotating platform 14, a pickup 15, an infrared sensor 16, a decoder 17, a video storage server 18 and a platform adjusting unit 19, and the positioning module 3 Including acoustic positioning beacon node 20, radio frequency receiving module 21, data control module 22, node processor 23, acousti...
Embodiment 2
[0030] Such as Figure 1-3 As shown, the smart bracelet 6 is worn on the examiner's hand, and after the time synchronization signal sent by the communication module 5, it can cooperate with the acoustic wave positioning beacon node 20 to perform time control on the node processor 23. Synchronization, after the time synchronization is completed, the sonic positioning beacon node 20 that sends out the ultrasonic positioning signal is fixed in the set classroom space and has specific position coordinates, and can receive the time synchronization signal transmitted by the smart bracelet 6 and the smart bracelet 6. The ultrasonic positioning signal sent by the smart bracelet 6 can decode the ultrasonic signal sent by the smart bracelet 6 to obtain positioning information by cooperating with the smart bracelet 6 to perform time synchronization after receiving the time synchronization signal. And transmit the positioning information to the monitoring module 4, when the monitoring mod...
Embodiment 3
[0032] Such as Figure 1-3As shown, the smart bracelet 6 and the camera module 2 are used to collect audio and video information inside the examination room and transmit the audio and video information to the monitoring module 4 through the communication module 5, and the smart bracelet The ultrasonic positioning signal sent by 6 is an ultrasonic signal using ultrasonic spread spectrum coding technology. The frequency band of the ultrasonic frequency positioning signal is 20K~25KHz. The heart rate detection module 11 is used to monitor the examinee's heart rate change information in real time, and when the examinee's heart rate exceeds the normal heart rate When changing the range, the dome camera 13 is rotated by the pan-tilt adjustment unit 19 to focus on monitoring the examinee. The dome camera 13 also includes a face recognition module, and the basic information matching module 9 is provided with A database of facial information for recognition models.
