| With the continuous development of science and technology,people’s quality of life in the city has been greatly improved.We use the letter to communicate with our friend it the past,and now we use the QQ and WeChat.We use carriage to go far away in the past and now we can take a ride on aircraft or highspeed rail.We used to pay in cash in the past and now we can use the mobile phone QR code payment to pay.The power of science and technology has changed our life in the city and has also contributed to the development of this era.Currently,there are more and more urban migrant workers,and most of them are in middle-aged.Even though they have old parents and young children,many middle-aged people leave the family for their livelihood.They come to faraway city and they will have no time to take care of the elderly and children at home.When the elderly and children need help at home,they can only make a phone call through the cellphone,there is no way for their children to help solving the problem.Nowadays,home electric appliances have more and more functions,which make them more complicated to use.Old people and children have far less learning ability than adults.That make it hard for them to use the electric applications.In addition,when people work far away from home,they are worrying about the condition of their family.It is necessary to contact the parents and the child in time.However,overly complex chat software,such as QQ and WeChat,required complicated operations to find the appropriate person for video calls.If only had a device and only need a button to contact the person you want to contact,it will be a very practical tool for children and the elderly.Therefore,designing a home monitoring system with remote assistance and one-touch remote video chat has very important practical application.In consider of above-mentioned problems,this paper adopts a widely used industrial computer as the hardware platform of the chat robot,and Ubuntu system as the software platform of the system.Combining embedded technology,Qt,Internet and other technologies to develop a set of remote control and remote video chat software system.STM32F103C8T6 is used as a controller for environment data acquisition and data transmission.The AD16 software is used to design the hardware circuit.Keil and IAR are used to develop the embedded software program.Finally,accomplish the data transmission and instruction execution between the controller and the industrial computer.The research work of the dissertation includes:1.System requirements analysis and overall design.After analyzing the needs of family security systems and chat assistance systems for the elderly and children in ordinary families,a monitoring system based on STM32F103C8T6 is designed and we designed the remote video chat and remote control software system to operate on IPC;2.The underlying hardware design of the monitoring system,including a central controller and three node terminal design;3.the system’s software design,including the underlying hardware software design and interface design based on Qt5.6;4.System integrated and tested.Building an environment in the laboratory,testing and debugging the stability of each module and monitoring the stability of the interface software.Finally,through all the above work,this article has completed the design of the chat terminal and achieved the requirements of the project.It has a good social value for the practical application of the family’s security and chat-assisted products. |
