摘要
设计了一种室内语音识别无线求救设备，其主要包括NRF24L01无线模块、LD3320语音识别模块、GSM通信模块．本设备工作时，以STM8L152单片机作为主控芯片，通过NRF24L01无线模块接收信号，由LD3320语音识别模块识别求救信号，由GSM通信模块实现GSM短信求救功能．
A kind of indoor speech recognition wireless distress equipment is designed, which includes NRF24L01 wireless module, LD3320 speech recognition module and GSM communication module.. This equipment uses STMicroelectronics stm81152 microcontroller as the main control chip, through nRF24L01 wireless module receives the signal, by ld3320 voice recognition module recognizes a distress signal, by the GSM corn munication module to achieve GSM SMS help function.
