Abstract ：along with the people living standard's unceasing enhancement, the family safe service is bringing to people's attention gradually. Establishes the networking alarm system in the residential district, enables the plot administrative center to carry on the stitch in time to inhabitant's police sentiment, is precisely the people hoped. Telephone equipment's large-scale popularization, causes the use public telephone network to realize the plot auto-alarm joint logistics system possibly to become. introduces one kind briefly by the public switched telephone network date transmission medium residential district
automatic peaceful against alarm system. The system by the micro controller core, the inhabitant provides the safe surveillance and the service to the plot, has the reliability to be high, the cost low, easy to popularize and so on merits. this article narrated based on plot housing intellectualization by public telephone network transmission medium "Intellectualization Residential district Safe Service system" the design with realizes. first, introduced this system's development background, the significance in the introduction. hereafter, this article elaborated the system hardware design process in the second chapter, had determined the type and component's choice, elaborated the system hardware circuit design, the hardware design structure diagram and to uses each kind of chip the function and the characteristic has carried on the detailed introduction; Analyzed the software design development process with emphasis in the third chapter, particularly master routine, gathering and demonstration subroutine and warning subroutine work flow. finally in connection and so on fourth chapter of concrete elaboration alert control software and hardware debugging.
Keywords : programmable logic controller ;program control;
