Abstract
The large-scale construction fire supervisory system mainly applies in each kind of high-rise construction, and in other public utilities, realizes reports to the police the function to these place early time, achieves the anticipated goal.
This kind of fire alarm system is a collection signal examination, the transmission, processing and the control and a body control system. This system uses American Analog Devices Corporation to develop, the production intelligence fire reports to the police the controller, the use special-purpose serial main line and the communication protocol, examines the detector can reflect fully the scene pyric factor and the non-pyric factor data acquisition central controller, the fire pattern which anticipated designs after the fire controller basis and, the judgment, realizes reports to the police accurately to the fire early time with the paraphrase should scene fire fighting equipment linkage control.
In order to adapt the different scale project application, is advantageous for the information long-distance transmission and the system installment, and the maintenance, this system uses the modular structure, the application many kinds of standard serial main line (for example RS-485 and so on) forms a network system. In this network system, the detector completes to the fire signal examination, then data transmission to fire controller. At the same time, each controller might corresponding report to the police through the RS-485 main line the information to pass to is located the different floor the lower position machine. Thus forms a complete fire protection, the early fire fighting local area network.
