Abstract

The invention relates to an examination room cheating recognition algorithm adopting sound array analysis. The algorithm comprises a support which is installed on each desk, a camera, a sound pickup and a button which are installed on the support, a processor which is connected with the camera, the sound pickup and the button, and a network module which is connected with the processor. The networkmodule establishes a data link with a remote management server, and the processor sets the cheating recognition algorithm. A method comprises the following steps: S1, the processor reads a sound signal of an environment through the sound pickup and recognizes a voice signal of a person; S2, the processor transmits a voice signal voice (i) acquired by the sound pickup and a face video video video(i) acquired by the camera to the management server; S3, the management server calculates a voice intensity E (i) of the voice signal voice (i), and performs comparing to obtain a maximum voice intensity E (imax); and S4, the management server provides a face video video (imax) for invigilators to judge.

Description

technical field [0001] The invention relates to a cheating identification algorithm in an examination room using sound array analysis, and belongs to the field of intelligent instruments and equipment. Background technique [0002] At the end of 2012, "machine replacement" gradually emerged in traditional manufacturing enterprises in Zhejiang and Jiangsu, and many enterprises have introduced modern and automated equipment for technological transformation and upgrading. In 2014, with the promulgation of the "Dongguan No. 1" document and various supporting policies, the "machine substitution" was carried out vigorously in Dongguan, the manufacturing center of the Pearl River Delta, and a "machine substitution" was set off across the country. wave. The reason behind this is that with the rise in labor prices, the "demographic dividend" of China's manufacturing industry is disappearing. Upgrading traditional industries with modern and automated equipment and promoting technolo...
