Abstract

A portable all-dimensional monitoring device for an examination room comprises an all-dimensional visual sensor used for obtaining overall video information in the examination room, a microphone used for obtaining audio information in the examination room, a digital wired or wireless transmission module used for transmitting a video signal and an audio signal in the examination room, a memory card used for saving video data and audio data in the examination room, as well as a microprocessor. The all-dimensional visual sensor is mounted above the middle of the examination room; a camera is connected with the microprocessor through an A / D interface; the microphone is connected with a voice-controlling chip; the microprocessor is connected with the digital wired or wireless transmission module, which is connected with an antenna; the memory interface for the memory card is arranged on the microprocessor; the memory card is inserted in the memory interface for the memory card. The invention can improve usage rate, be applied conveniently and has lower cost.

Description

technical field [0001] The invention relates to examination room monitoring equipment, in particular to the application of omnidirectional visual sensor technology, embedded microprocessor software and hardware technology, and network technology in examination room monitoring. Background technique [0002] Examination is an important means of selecting talents. With the continuous development of modern information technology, the cheating methods in the examination room are characterized by high technology, diversification, and strong concealment. The traditional human invigilation can no longer meet the expected invigilation requirements. At the same time, fraud has also begun to spread to various fields. In addition to the well-known high school entrance examination and college entrance examination, fraud in civil servants, doctors, lawyers, architects, supervisors, skills training, postgraduate admissions, and declaration of professional titles are often exposed by the me...
