Research On Safety Protection System Integration Method In Intelligent Building

With the improvement of the people's living level, the continuous increase of working pressure and the continuous pursuing for the comfortable life, the security of family and working environment are paid attention to.Due to the continuous development of sensing technology, control technology and computer technology, the safety protection methods have been changed from previous high wall and heavy gate to nowadays intangible wall that is more safety. Because the technology is still in developing, the various products are existed in the market. Some of them are of better stabilities and high safety coefficient, but the price is more expensive. Some price is relatively cheaper which can be borne by the ordinary community, but performance is not steady enough, less function is supplied and fail to report or wrong report are occurred frequently. So it is very important to design a set of safety protection system which has high safety coefficient and lower price.The main work of this thesis is to design fire protection system, security system and peripheral protection system and realize system integration design for three subsystems.The whole system is divided into two parts, which are the indoor system and outdoor system. The active infrared detection system is selected as peripheral protection system in outdoor system. The light beam generated by active infrared detection system produce an invisible fence line. Output signal of active infrared detectors a re send to PLC in order to transmit to central control unit. The fire detectors and passive infrared detectors are selected as indoor fire alarm and anti-theft alarm system and the alarm information can be transmitted to communication unit by wireless method then to central control unit by means of modem.The central control unit consists of a computer system. The software of Kingview which is for industrial control is used to integrate all information coming from PLC and communication unit.Advantage of the system is that the technology used is ripe, system runs stable and the price is relatively low. It is used successfully in Liaoning Guodian energy conservation environmental protection limited company. The reflection of user is fine. It is of popularizing value.
