At the same time, developt a good performance, high reliability alarm system on the prevention of fires, gas leak, and other incidents in social life and property caused serious losses is of great significance.The whole system hardware circuit design is reasonable and reliable performance. First-alarm on the existing technology, development trends and the development of the multi-function alarm significance, leads to the development of multi-function alarm necessity and feasibility. Secondly, discuss the realization of the programme on the development of the multi-function alarm, by comparison,and comprehensive consideration choose one of the programmes to achieve the multi-functionalarm. Thirdly, identify options, the use of such programmes on the realization of multi-function alarm some of the hardware design and software design part. Finally, summin
