Abstract

The invention discloses a voiceprint-based intelligent device opening and closing control system, and particularly relates to the housing management field, the voiceprint-based intelligent device opening and closing control system comprises a voiceprint confirmation system and an opening and closing system, the voiceprint confirmation system comprises a voiceprint collector, data collected by the voiceprint collector is transmitted to a voiceprint feature extraction module, and the voiceprint feature extraction module is used for extracting voiceprint features; data of the voiceprint feature extraction module is transmitted to a PLC (programmable logic controller), the PLC is in data interaction connection with a data memory, and a control signal output end of the PLC is connected with a display and a frequency judgment module; through the designed voiceprint confirmation system, operation of the opening and closing system can be controlled through voiceprint during use, so that a user can directly use sound to open the box, and through the designed frequency judgment module, the display and the alarm module, the safety and reliability of the verification process are improved. And the reliability and the convenience in use are further improved.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a system for controlling the opening and closing of intelligent equipment based on voiceprints. Background technique [0002] Voiceprint recognition, a type of biometric technology, is also called speaker recognition, including speaker identification and speaker confirmation. Voiceprint recognition is to convert the acoustic signal into an electrical signal, and then use a computer to identify it. Different tasks and applications will use different voiceprint recognition technologies. For example, identification technology may be required when narrowing the scope of criminal investigation, while confirmation technology is required for bank transactions. [0003] In the prior art, most of the equipment used for opening and closing control adopts voiceprint confirmation technology, and most of the unpacking operations still use conventional forms such as mechanical locks, passwo...
