Embodiment 1

[0027] An exam certification system applied to big data voiceprint recognition candidates, the hardware structure is installed at the entrance of the exam room, which includes a pickup 1, a codec device 2, a digital signal processing chip 3, a data storage 4 and a release device 5. The pickup 1 is connected to the codec device 2, and the audio signal collected by the pickup 1 is input into the codec device 2 for A / D conversion. The codec device 2 is connected to the digital signal processing chip 3, and the audio signal converted by the codec device 2 is transmitted to the digital signal processing chip 3 for analysis and processing. The digital signal processing chip 3 is connected with the release device 5, and the digital signal processing chip 3 generates a corresponding control signal according to the audio signal and controls the opening or closing of the release device 5. In addition, the digital signal processing chip 3 is also connected to a data storage 4, which is u...

Embodiment 2

[0030] On the basis of Embodiment 1, the pickup 1 includes a pickup housing 11, a sound-introducing component 12, a fixed pressure plate 13 and a retaining spring 14, and the sound-introducing component 12 and the fixed pressure plate 13 are mounted on the sides of the pickup housing 11, respectively. Inside, the snap ring 14 is set and fixed on the inner side of the pickup housing 11 above the fixed pressure plate, and the purpose of installation and disassembly can be easily achieved through the snap ring structure, and the component structure will not be damaged during the disassembly process. There is a rotatable turntable 131 in the middle of the fixed platen 13 , and the turntable 131 can rotate around the center of the fixed platen 13 on its plane. Further, a plurality of small holes 132 are uniformly arranged on the disc surface of the turntable 131, and the size of the small holes 132 is consistent with the size of the sound inlet hole 21 of the sound inlet part 12, an...

Embodiment 3

[0032]On the basis of Embodiment 1 or Embodiment 2, the codec device 2 is selected as a codec device 2 produced by TI Company as TLC320AD50C, and the TLC320AD50C codec device 2 is a 16-bit high-performance audio signal codec chip. Contains anti-aliasing filter and reconstruction filter, the highest sampling frequency can reach 22.05kHz, and can be set through external programming. The chip has a synchronous serial communication interface (SPI) that can be connected with many DSP chips; it adopts two sets of analog inputs and two sets of analog outputs, has sufficient common-mode rejection capability, can work in differential or single-ended mode, input gain The output attenuation and output attenuation can be controlled by external programming; it adopts a single 5V power supply or a combined power supply of 5V and 3.3V, and the maximum power consumption is 120mw during operation; it is small in size and suitable for portable devices. In order to offset the interference from t...

Abstract

The invention discloses an examinee examination authentication system applied to big data voiceprint recognition, belongs to an examinee examination authentication system hardware structure in the technical field of identity authentication, and aims to provide the examinee examination authentication system applied to big data voiceprint recognition. According to the technical scheme, the examinee examination authentication system comprises a pickup arranged at the entrance of an examination room, an encoding and decoding device, a digital signal processing chip, a data memory and a discharging device, wherein the pickup is connected with the encoding and decoding device; the encoding and decoding device, the data memory and the discharging device are all connected with the digital signal processing chip; an audio signal acquired by the pickup is transmitted to the digital signal processing chip after being subjected to A / D conversion through the encoding and decoding device, and the startup or shutdown of the releasing device is controlled through the digital signal processing chip. The invention is suitable for the hardware structure of the examinee examination authentication system.

Description

technical field [0001] The invention belongs to the technical field of identity authentication, and relates to a hardware structure of an examinee examination authentication system, in particular to a hardware structure applied to a large data voiceprint recognition examinee examination authentication system. Background technique [0002] As the scale and number of various examinations increase year by year, although the examination management organization has taken various measures to prevent them, it still cannot effectively eliminate the phenomenon of substitute examinations. The fairness and impartiality of the examination violated the interests of candidates and disturbed the social order. At present, in all kinds of examinations, candidates enter the examination room with the admission ticket, and the monitoring teacher can only judge whether the photos of the candidates on the admission ticket are consistent with the naked eye, and there is no guarantee that candidate...
