Intelligent face-scanning terminal voice alarm method, system and device, and medium

Abstract

The invention discloses an intelligent face-scanning terminal voice alarm method, system and device and a medium. The method comprises steps that a safety CPU and a multimedia CPU are made to be powered on and started, and the safety CPU and the multimedia CPU are made to communicate with each other; the security CPU performs security mechanism detection, judges whether the security of the face-scanning terminal is triggered or not, if yes, removes sensitive information, resets the multimedia CPU and sends an alarm instruction to the multimedia CPU, meanwhile, the security CPU interrupts the communication with the multimedia CPU, and the multimedia CPU outputs a preset alarm voice audio digital signal, otherwise, the security CPU authenticates the instruction of the multimedia CPU, startsand operates the Android system, and sends an alarm signal; financial transaction operation is carried out, and an audio digital signal of the transaction operation is outputted by the multimedia CPU;and the audio decoder decodes the audio digital signal to output an analog audio signal, and the analog audio signal is amplified by the power amplifier to drive the double loudspeakers to perform voice broadcast. The method is advantaged in that a buzzer acoustoelectric device is not needed, voice alarm is achieved, design cost and manufacturing cost of equipment are reduced, and meanwhile the man-machine interaction experience is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a voice alarm method, system, equipment and medium for an intelligent facial recognition terminal. Background technique [0002] Existing intelligent facial recognition terminals with physical security mechanisms, especially transaction terminals, such as POS machines, when security is triggered, the electroacoustic device for audio alarm uses a buzzer, and the buzzer is only controlled by the security CPU. It is used for the output of the alarm audio when the safety mechanism is triggered. The pulse signal output by the safety CPU is amplified to drive the buzzer to emit a sound of a certain frequency, such as the sound of "dididi". On the one hand, the buzzer is used for alarming , which is limited by the specifications of the buzzer, the alarm sound is small, about 70-80dB, the audio alarm output is single, the recognizability is poor, and the human-computer interact...

[0002] Existing intelligent facial recognition terminals with physical security mechanisms, especially transaction terminals, such as POS machines, when security is triggered, the electroacoustic device for audio alarm uses a buzzer, and the buzzer is only controlled by the security CPU. It is used for the output of the alarm audio when the safety mechanism is triggered. The pulse signal output by the safety CPU is amplified to drive the buzzer to emit a sound of a certain frequency, such as the sound of "dididi". On the one hand, the buzzer is used for alarming , which is limited by the specifications of the buzzer, the alarm sound is small, about 70-80dB, the audio alarm output is single, the recognizability is poor, and the human-computer interaction experience is not good; During normal trading operations, voice broadcast and other functions are needed. In order to better realize the audio broadcast function and improve the loudness and quality of audio broadcast, the terminal must be equipped with a speaker. In this way, the number of electro-acoustic devices in the structural design of the product increases, which also makes The number of openings increases, the design complexity increases, the assembly process and difficulty increase, and the cost of the whole machine also increases
