Design And Implementation Of Intelligent Voice Interactive Sand Table Control System Based On STM32

With the rapid development of modern science and technology,our lives have stepped into full-automatic and intelligent era.The emergence of intelligent products brings us more convenience,and the means of presenting information are more rich and interesting,which also prompted the intelligent sand control system ushered in the rapid development.At present,traditional sand table can only control the switching effect of sound,light and electricity through manual control switch or a laser pen click on the corresponding region,which can't achieve a simple and convenient control and bring great limitations to users.In order to improve the situation,this paper designed a low price,full-featured,cost-effective and convenient multimedia sandbox intelligent control system based on STM32F103R8T6 according to the current situation and future trends of domestic and foreign sandbox control system,which also combined the characteristics of development direction of sandbox intelligent control system with embedded electronic equipment,and fully considered the user's using perception,installation convenience,price,and the richness of information display.The system chose the 32-bit microprocessor STM32F103R8T6,based on the Cortex-M3 core,as the hardware core to carry on the system's hardware design.Then,the overall hardware framework and each part of the circuit were designed.The ?C/OS-II real-time operating system was selected as the core and be transplanted,and the low-level hardware drivers and the top-level application program are designed based on the ?C/OS-II system.The mobile client and server-side application development were completed by using Java language in the Android environment,and the development of the database was achieved by using MySQL.The biggest characteristics of this system are flexible control and diversification of communication.This system embarks from the view of intelligence and information combing the intelligent terminal,voice recognition,wireless communication with sandbox model to make it possible that users only need a mobile terminal,they can control the display effect of sound,light and electricity by the voice or touch the button.Finally,the sandbox control system is tested.The integration testing results show that the intelligent sand table control system is running normally and meets the design requirements.
