Based on monolithic integrated circuit's fire alarm apparatus
Abstract: Designed automatic fire alarm system, which through a controller to issue a fire alarm fire alarm signals, fire alarm control signal received by the police immediately after the issue of sound and light alarm. The design of the detection device by ion sensor smoke UD-02 and a complete set of application specific integrated circuit components, such as DQ-295, through on-site collection of the fire parameters, A / D converter, address coding, and then transmitted to the single-chip by the corresponding single-chip processing to determine whether the fire scene. This single-chip signal processing for fire model will determine , based on when the fire broke out, fire development and changes in the law of the parameters to identify true and false fire, different from the traditional valuation of a single judge of the way and will be beneficial to determine the accuracy of fire sexual.
