A voice alarm method, system, device and medium for an intelligent facial recognition terminal

Abstract

The present invention provides a voice alarm method, system, device and medium for an intelligent facial recognition terminal. The method includes: powering on and starting the security CPU and the multimedia CPU respectively, and communicating with each other between the security CPU and the multimedia CPU; Whether the terminal security is triggered, if so, clear sensitive information, reset the multimedia CPU, send an alarm command to the multimedia CPU, and at the same time, the security CPU interrupts the communication with the multimedia CPU, and the multimedia CPU outputs a prefabricated alarm voice and audio digital signal, otherwise, the security CPU authenticates Multimedia CPU commands, start and run the Android system, and perform financial transaction operations. The multimedia CPU outputs audio digital signals for transaction operations; decodes the audio digital signals through an audio decoder to output analog audio signals, and amplifies them through a power amplifier to drive dual speakers. Voice broadcast. The present invention does not need a buzzer, an acoustic appliance, realizes a voice alarm, reduces the design cost and manufacturing cost of the device, and improves the human-computer interaction experience at the same time.

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
