Design Of Central Control Module For Smart Home System Based On Voice Interaction

Based on computer technology,wireless sensor network technology,wireless communication technology,artificial intelligence and other advanced technologies,modern smart homes integrate home appliances,sensors and other smart devices through the home control center module,providing users with a human-oriented,convenient,healthy,safe,and intelligent home environment.Focused on the issue that most of the smart home products on the market are controlled by mobile client,which brings inconvenience to users,a smart home central control module with voice interaction function was designed.The application of voice interaction technology in the field of smart homes makes the interaction more natural and efficient.Based on speech recognition technology and ZigBee technology,the central control module consists of IFLYTEK AIUI speech recognition module,ZigBee communication module,microphone array etc.Integrated IFLYTEK SDK,a speech recognition program was written to realize voice control of household equipment.At the same time,local and remote communication software program were designed to realize local communication between mobile client and central control module and remote communication between central control module and Ali cloud server.In addition,the system's update and maintenance functions are realized.This function is of great significance for maintaining the stable operation of the current system and the extension of future functions.Finally,an experiment was designed to test time-delay and packet loss rate of local and remote data transmission.The test results show that the average delay of local transmission is 40ms,the packet loss rate is 0.038%,the average delay of remote data transmission is 607ms,the packet loss rate is 0.16%,so the real-time and reliability of data transmission can meet the practical application of smart home.
