FIRE DETECTION SYSTEM

摘要

A fire detecting system is provided to promptly inform a building manager, an administrator and a disaster prevention center of fire by using wire or wireless communications. A fire detecting system comprises a heat sensor(15), a smoke sensor(17), sensing units(11,13), an amplifying circuit(21), a microprocessor(40), a fire displaying unit, a communication interface unit(72) and a relay driving unit(77). The heat sensor senses the heat. The smoke sensor senses the smoke. The sensing units include an UV sensor and an IR sensor. The amplifying circuit amplifies the signal of the sensing units. The signal of the amplifying circuit is inputted to the microprocessor. The fire displaying unit is connected to an outputting terminal of the microprocessor. The communication interface unit transmits a fire signal to a disaster prevention center and a mobile communication terminal. The relay driving unit is connected to the outputting terminal of the microprocessor.
