Intelligent door lock double-platform voice playing device and implementation method

Abstract

The invention discloses an intelligent door lock double-platform voice playing device. The device comprises a single-chip microcomputer and an ARM LINUX, the single-chip microcomputer and the ARM LINUX serve as a prompt sound recording and playing platform and a voice audio recording and playing platform of an intelligent door lock body respectively, and a playing platform of the single-chip microcomputer and an ARM LINUX playing platform do not interfere with each other when working. An implementation method comprises four steps. Double platforms of MCU + ARM LINUX are used for recording andplaying prompt sound and recording and prompt sounds are realized through an MCU playing platform. The recording time is long without affecting sound quality so that good experience is brought to a user. The performance of the intelligent door lock body is fully improved, and the market competitiveness of a product is improved. The defects that an existing intelligent door lock adopts a single-chip microcomputer to process prompt sound and record audio at the same time, the processing capacity is limited, the sound distortion degree is large, the user experience is poor, and recorded voice files are relatively small are overcome.

Description

technical field [0001] The invention relates to the field of intelligent lock equipment and its application method, in particular to an intelligent door lock dual-platform voice playback device and its implementation method. Background technique [0002] With the development of science and technology, the application of smart door locks is becoming more and more extensive. Because it can be unlocked without a key (usually through mobile phone APP or face recognition, fingerprint recognition, etc.), and has better anti-theft performance, it is more and more used in the home or production fields. Smart door locks generally have the function of prompt sound and software recording. Among them, the prompt sound is generally the prompt operation sound in the user's switch lock; the software recording function is mainly in the application, and the user can leave a message for one or more other users who switch the smart door lock (such as the warehouse door) through the recording ...

AI Technical Summary

Problems solved by technology

[0003] The existing smart door locks process the audio signal through its internal MCU (single-chip microcomputer). Since the single-chip microcomputer also needs to perform calculation and control of other processes of the smart door lock, it has the problem of limited processing capacity. Among them, the voice (including the prompt tone and the sound recorded by software) is often output at a lower sampling rate, the sound distortion is relatively large, and the user experience is not good

Furthermore, due to the limitation of the MCU's own memory capacity, the recorded voice file is not easy to be too large, resulting in a limitation of the recorded sound duration. In this way, when the user needs to record a long audio content, it cannot be satisfied. application poses certain constraints
