Based On Embeded Household Environment Intelligent Surveillance System Research

Along with the progress of the society, the rapid development of science and technology, human civilization also has reached an unprecedented situation. People in the material and cultural life reach "uantity" meet, but also gradually realize the importance of "quality", namely, the quality of life. A house is no longer merely by a house and a few pieces of simple furniture composition of the premises, but a zhefengdangyu homeowner life interest embodies the stage of life philosophy and. With the arrival of information age 21 century, the social informatization and household intelligent also appeared a vigorous development trend, the progress of science and technology to people living brought great changes, and to make the high quality with high-tech security comfortable household life has gradually being neglected and chase high in efforts to development, human science and technology, but also enjoy the information age and high-tech brings the convenience of the life.This paper first briefly introduces the information era in the background of the origin, intelligent household the development situation of the domestic and abroad, secondly introduces ARM embedded processor and embedded operating system UCII development status, and then discusses the multisensor data fusion and fuzzy comfort, and finally presents the principle of environmental monitoring system of intelligent household hardware design and software design. The household intelligent monitoring system consists of two main components, namely household fresh air system and security system. Hardware mainly includes ARM selection, master module gas sensors selection and adaptation circuit design, security alarm class sensor selection and adaptation circuit design, alarm I/O circuit design, fan driver circuit design, relays, keyboard and liquid crystal display circuit design, alarm music module design, etc. Software UCII in LPC2220 mainly include the transplantation, sensor signal frequency-field program, fan PWM waves driver, liquid crystal display program, I/O port, input and output control program of multisensor data fusion program, fuzzy comfort judgment procedures, etc.The household environment intelligent surveillance system, mainly by two big module composition, namely fresh air system and security systems, in line with low carbon, energy-saving, environmental protection concept of life, choose in the control field ARM7 processor comparatively mature to replace PCS, as whole household environment monitoring system for the main controlling module, household environment for testing and control, and presents the system function and structure diagram, and hardware principle diagram and software design concept and main program.
