基于语音识别的空巢老人居家报警系统设计

Voice Recognition Based Alarm System for the Elderly Living Alone

设计了一款老人在家呼喊就能及时联系上家人的装置,同时报警信息可以上传到云平台,方便警务、医疗系统及时开展救援。设计采用语音识别模块实现报警语音的识别,同时识别结果通过串口传输给主控模块。主控模块根据报警信息向GPRS模块发送相应指令,从而实现给多个紧急联系人发短信和打电话的功能。报警信息通过WiFi模块上传到OneNET云平台,期间系统接到紧急联系人的来电可以自动接听。最后,通过对该报警系统的语音识别正确率及稳定性进行测试,实现了预期设计目标。

In this paper,a device which is designed to recognize the help from the elderly and call family members.In addition,the help-seeking information can be uploaded to the cloud platform,which will be convenient for the police and hospital systems to assign the rescue plans in time.The voice of help will be recognized by the voice recognition module and the recognition results will be sent to MCU instantly,which then will make a number of phone calls to family members by sending commands to a GPRS module.In the meantime,this information will be uploaded to the OneNET cloud platform via a WIFI module.Hereafter,the phone calls from previously-setting family members can be picked up automatically.At last,the function of the system is realized after lots of tests.
