The Design And Implementation Of Intelligent Audio And Video Equipment Control And Service Management System

With the development of embedded technology,the application of intelligent control of audio and video equipment systems is more extensive,but the traditional intelligent control system of control system integration is not high,and the price is expensive,which is difficult to meet the accurate needs of users.Intelligent audio and video equipment control and service management system based on embedded technology and wireless communication technology,designing matching audio and video control system according to user's needs,with good human-computer interaction experience in control process,easy to operate,flexible construction Satisfied with the control system that meets the needs of users.First,review the relevant data to analyze the system requirements,this paper has established the design principles of the audio and video equipment control and service management system,divide the various modules of the system functions,and build and configure the corresponding development environment.Secondly,the hardware block diagram and circuit schematic diagram of the system main control board and core sub board are completed.The main control board is designed based on STM32F103RCT6 microcontroller,and integrates memory module,relay control module,network communication module and infrared transmitting module.The design of the core sub-board integrates 16 serial communication modules,1 display module,8 button control modules and 1 infrared receiver module.Using the keil5 design system to control the peripheral logic running software of the peripheral logic,the corresponding hardware circuit lower software design includes infrared remote control module,RS232 serial port and RS485 serial port module,analog I/O module,relay module,liquid crystal display module,command storage and call The module,the command trigger module and the online upgrade module complete the communication protocol interface design and packaging,and realize the communication and control between the upper computer and the lower computer.The PC software mainly includes three parts: intelligent interactive management platform software,infrared learning software and touch screen and mobile device APP software.The design of the intelligent interaction management platform uses the friendly human-computer interaction interface to complete the parameter setting and command input of each control instruction,and the application communication protocol interface software package realizes the functions of uploading,calling,triggering and saving the command data.Infrared learning software completes the functions of learning,uploading,saving and transmitting infrared commands of various devices.The touch screen interface design software completes the interaction interface and function button design of portable mobile devices such as Android mobile phones and IPAD tablets,and realizes the remote control function of the system by replacing the files in the designed APP software.This project ompletes the design and development of system hardware and software,and perform module function test and overall performance test.The results show that the designed intelligent audio and video equipment control and service management system has perfect functions,simple operation,meets the needs of enterprises,and the performance index is better than similar products on the market,achieving the expected results.The hardware and software of the system have been commercialized,installed and applied to multiple locations,and the system is running stably and in good condition.
