Household Automatic Alarm System Design And Implementation

With the development of the Information Technology and the Society, people pay more attention to the security of the family. So people select modern technology to guard against burglary.Compared the advantages and disadvantages of the automatic alarm system with each other, the thesis choose the GSM short message system. It has a vast world. The researches on automatic alarm system are very deep, but the most researches are divided, transducer or GSM short message or the design of the software, not the whole. The thesis design the whole automatic alarm system based on the GSM short message.Based on GSM short message,an intelligent alarm and remote control system which made the high performance microcontroller C8051F330 as the core was presented. The system could be connected to the various wired or wireless sensors to achieve the home security alarm and remote control by the short message.Different kinds of contingencies gathering by sensors in house and reported to MCU in time by inner wireless network established. GSM module with the control of MCU utilizes the GSM and sends the warning information by short-message to the beforehand fixed telephone numbers, achieving the long-distance wireless warning function. Furthermore, there is no need wiring for sensors, so the system has aboard value of business popularity. From several aspects,such as system structure,working principle,hardware and software design,the intelligent alarm and remote control system was narrated.The principle schematics, the PCB and the software have been designed, and the explanation and universal property are considered. The Serial debugger of the GSM short message module and PC is carried through.
