Because it is small and convenient to install and the ratio of performance and cost is high, it will have a bright future. But the product of alarm for family has some disadvantages. It is necessary to do some research on a new type of product based on the former product, which is valuable for protecting people39。s possession and increasing the reaction of policeman, fireman, doctor and vigilance mittee. This dissertation improves the former alarm for family in which the mobile modem module is intzoduced. So the alarm can be set by telephone and mobile phone, which overes the shorting that the system will be out of work when the telephone line is cut off deliberately. The alarm is designed by modular method. The alarm is subdivided into three parts at include the main module, mobile module, collecting information on alarm module. According to different requirement and expense, the custom can purchase different modules bine the product that is suitable for them. The main module is the key group of the alarm. The others are the function ponents, which are connected conveniently with the main module. There are interfaces to connect with the function modules and software to drive the function modules in the main module, which enables the function modules to plug and play. This dissertation describes the design of hardware and software of the alarm in detail, in which selecting suitable chips, periphery circuit, chips interface, and the methodology of program are discussed. Moreover. the key program is described. The alarm that is satisfied for the custom is developed in terms of the requirement of project. The development trend of alarm is discussed in the end.
