Design And Implementation Of Smart Home System Based On MSP430

In the past few years, people have witnessed the miracle of social development brought by science and technology. Owning to people’s higher pursuit of living condition, smart house starts to play an important role in people’s daily life. Smart home will combine all kinds of electrical appliances in the family as a whole entity, controlled together, so it can give us an efficient and superior environment of life. However, how to put forward a set of standard and accepted home furnishing smart system smart becomes a question alone with people’s life.Focusing on the problems of high prices and complicated wiring problems that smart house is facing, the present study is trying to design a wireless control system of smart home based on the MSP430.The main research of this design is using a single chip microcomputer MSP430 with low power consumption as main control equipment, integrating into many kinds of sensor technologies, using nRF24L01 and PT2262/PT2272 wireless transceiver chips to form an inner home network, and realize the remote communication through the GSM module to design a practical and economical smart house system. The main content of the research is the function of detection and security, realize long-distance and short-range wireless transmission.It divides hardware design into the master control module and associated control module. The designer draws the circuit principle diagram of master control module and associated control module by using Altium Designer software. On the basis of the hardware circuit design, the designer ensures the working process of the software. The program is code by C language according to software process and compile in the IAR Systems environment, guarantee coordination of the system work by copulate debugging of the software and hardware. Finally,this system is emulated by using the simulation software of Proteus to ensure the feasibility of this scheme. Then, test the system of hardware system to show that the system realizes the home furnishing environmental monitoring, environment alarm under abnormal conditions,home Furnishing internal wireless communication and the remote communication function home furnishing external.Smart home control system of the present study is integrated with the technology of wireless communication, avoiding the trouble of family wiring and achieves three kinds of environmental detection and four abnormal conditions. If so, it trying to form a set of smart home control system with low cost, low power consumption, simplicity of operation. It is convenient to fix a whole smart house system which will be suitable for a normal family. The design of smart house will have a great practical significance.
