This design has the fire automatic-detection which the monolithic microcomputer controls to report to the police the controller, turns on the smoke sensor and the temperature sensor the monolithic microcomputer, after microcomputer operation and logical judgement, Reports to the police the integrated circuit after the special-purpose acousto-optics to carry on the fire to report to the police. Because monolithic integrated circuit integration rate higher, therefore this design has the structure simply, reliability good, the cost is low and so on the merit.
As a result of the modern architecture enterprise fast development, the request has the fire in the modern architecture to report to the police down to the automatic fire prevention system, based on this goal, has used the AT89C52 monolithic integrated circuit carries on the design, greatly enhanced the system intellectualization and the reaction rate. Also this design may simultaneously use in to monitor many regions, its principle of work and this article introduced the content basic is same.
