Abstract

The invention relates to a power drive output device and method for a fire fighting device, belongs to the technical field of control, and solves the problems of fixed response time and magnification of the existing polarized relay and small power drive current. The power drive output device includes a fire alarm signal acquisition circuit and a power drive circuit. The fire alarm signal acquisition circuit includes: a flame susceptor, which senses the flame temperature and converts the flame temperature into a differential voltage; an amplifier circuit, which amplifies and outputs the differential voltage output by the flame susceptor; a voltage comparator, which compares the voltage output by the amplifier circuit with the reference voltage, and judges whether there is a fire alarm signal according to the comparison result; and a power drive circuit, which is connected to the output end of the fire alarm signal acquisition circuit, and controls the power when there is a fire alarm signal. The drive circuit provides enough drive power to drive the fire fighting device. It realizes configurable magnification and response time, and at the same time its power drive current is large and its performance is stable.

Description

technical field [0001] The present invention relates to the technical field of control, and in particular, to a power drive output device and method for a fire fighting device. Background technique [0002] The flame susceptor is composed of various combustion products, intermediates, high-temperature gases, hydrocarbons and inorganic substances as the main body of high-temperature solid particles. The thermal radiation of flame has discrete spectrum of gas radiation and continuous spectrum of solid radiation. The flame radiation intensity and wavelength distribution of different combustors are different, but in general, the near-infrared wavelength domain and the ultraviolet light domain corresponding to the flame temperature have a large radiation intensity. According to this characteristic, a flame sensor can be made. [0003] The input signal of the polarization relay of the three-proof control box comes from four groups of independent flame sensor differential voltage ...
