The Rebuilding Of Smart Student Boarding House Based On Microprocessor System

With great improvement of people's living standard, the rapid development and abroad application of microelectronics, automation and computer ability, the research and application of security system of Smarthome are more and more successful. The college is an important institution where the country cultivates talented person. Along with deepening high education's reform of our country, the change of campus area, number of students and function of the college brings on new demands to security management of campus. The security of campus attracts people's attention. Nowadays, science and technology develop fastly. Changing the safeguard measurement of campus by technology is an important way to build a safe campus.This text analyzes the structure feature of the present colleges and problems of the management encounting. It also suggests the constructure project of campus security system .According to the special situation of college, we will rebuild smart Student apartments. Basing on the development direction, the survey of security technology of Smarthome overseas, the situations of our countries and the college security environment and demand, we have researched and designed a kind of intelligent alarm system for Student apartments basing on single chip microprocessor system. It is a creation of applying Smarthome techology in Universities. It includes the functions of theftproof, fireproof, energy saving and daily display. Meanwhile, in addition to displaying the time and temperature, performing automatic detection and automatic alarm, it also puts forward the approach of apartment energy-saving control. It has some innovation significance. Pyroelectric infrared is used for detecting theftproof and controlling power. Water saving control is achieved by rebuilding of traditional water meter. Temperature sensor and Phoroelectric smoke sensor are integrated to a compound detector for fireproof. The multi-sensors make the least fail to alarm and false alarm, so that it enhances the reliability of the system. When detectors detect any abnormality signal or energy saving signal,an interrupt request will be sent to the MCU. Then the MCU will control the system depending the judgment and performance of the procedure. In addition,the code validation has been intercalated in the system. Users can input and modify the code by keyboard. In order to build up the systemic security and stability, the system has standby power supply and can inspect whether the wire and the power break or not.This system not only can provide security alarm, but can use the resourse at different time according to the software coordination. It can save much more hardware resourse. The suggestion of energy-saving module has some positive effect on constructing saving type campus and improving the conscious of energy-saving. The system can work stability and achieve the design purpose basing on a great deal of correlative experiments, hardware and software's emulation. The result also proves that it has some definite practicability. As far as research and exploitation, this has some definite significance of reference.
