Design And Implementation Of The Speech Home Control System Based On ARM

In recent years,with the rapid improvement of social productivity and the rapid development of science and technology,technology has brought more convenience to people's lives.Among them,the related series of smart home products are close to life and have been favored by people.The development trend of the modern home furnishing industry.However,the current smart home market has various problems,such as high cost,high complexity,inconsistent standards,and differences between products and people's needs.These problems are not enough to meet people's needs for smart and convenient lives.In order to improve this situation,this article determines the overall scheme of the system from the perspectives of practical convenience,green energy saving,safety,reliability,and compatible interconnection.The STM32F103ZET6 processor is used as the main controller,and the ZigBee technology is used to establish an internal communication network in the home.The common speech recognition algorithms are compared and analyzed.The speech recognition system is applied to the embedded platform.The two controls "Voice control and touch screen control" are designed according to the system function.The hardware and software of the system are designed according to this solution.In the hardware design part,the system is divided into the main controller module,voice recognition module,LCD module,WIFI module and ZigBee wireless network part.The core module of ZigBee wireless network is designed with CC2530 MCU in the wireless network.Based on this core module,the coordinator and environmental information acquisition terminal,intelligent curtain terminal,socket appliance control terminal and infrared appliance control terminal are designed.The main controller module is the control core of the system;the voice recognition module converts the user's voice information into control commands;the LCD module is the system's human-computer interaction interface,which can display the current status of the system and can also control home appliances by touching the screen;WIFI The module can be connected to the Internet through a home router,and it can obtain Beijing time and local weather from the network.The environmental information collection terminal can detect the home environment information,such as temperature and humidity information,etc.;smartcurtain terminal,socket appliance control terminal and infrared appliance control terminal Control of main home curtains and household appliances.In the system software design part,the system main program is written based on the ?C/OS-? operating system.At the same time,the software system is divided into several tasks according to the modular design,and each task is given a different running priority.All tasks have good real-time performance.The program design of each terminal of the system is based on the functions of each terminal in the Z-Stack protocol stack,and corresponding application programs are written.Finally,the intelligent home control system designed in this paper is tested experimentally,including speech recognition accuracy test,voice control test,and touch screen control test.The test results show that the control system designed in this paper can correctly execute the control commands issued to the terminal node under the voice control mode and the touch screen control mode,and the system runs stably..
