The gas flame sensor is characterized in that a voltage stabilizing circuit is electrically connected with a power supply; a booster converter is electrically connected with the voltage stabilizing circuit; a photoelectric converter is electrically connected with the booster converter; a signal comparator is electrically connected with the photoelectric converter; a light alarm device is electrically connected with the signal comparator; a controller carries out outputting by an electrical signal; and a red ultraviolet light sensitive tube is electrically connected with the photoelectric converter. The flame sensor provided by the utility model has advantages of far detection distance, short corresponding time, low false alarm rate and stable performance.
Description
Technical field
The utility model belongs to sensor field, specifically a kind of flame sensor.
Background technology
Flame sensor is the sensor that is used for specially searching burning things which may cause a fire disaster, and existing flame sensor is divided into three kinds according to the light characteristic of flame:
1. the infrared light radiosensitive infra red flame sensor long to the flame medium wavelength is the highest mainly for detection of near wavelength its sensitivity when 760nm～1100nm scope endogenous pyrogen signal, particularly wavelength is 940 nanometers; Its shortcoming is that signal is strong and weak with the burning things which may cause a fire disaster size, apart from the burning things which may cause a fire disaster distance relation of being inversely proportional to, take candle of 5V power supply as burning things which may cause a fire disaster, and output 4.8V when 0.3V is apart from fiery 20cm during without fire, output 2.9V during apart from fiery 50cm;
2, to the ultraviolet flame sensor of the shorter ultraviolet radiation sensitivity of flame medium wavelength, work in wavelength 160nm～290nm, because device works in middle ultraviolet band, be positioned at the solar spectrum blind area, make detection system can avoid lamp, the system signal detection difficulty is descended, and rate of false alarm significantly reduces; The tool of this device " day blind " characteristic own, thereby it is high to have sensitivity, has the advantages that atomic Testing of Feeble Signals ability and reaction time are exceedingly fast; Monitoring distance: 0～20 meter;
3. survey simultaneously the long ultrared ultraviolet of the shorter ultraviolet ray of flame medium wavelength and wavelength/infrared composite flame sensor.One of them uses the insensitive ultraviolet flame sensor of sunshine, and another passage uses the infra red flame sensor that is operated in specific Fire Radiation center frequency range, is used as the affirmation sensor that flame detects.Its fastest response time is 500ms.
Summary of the invention
Technical problem to be solved in the utility model is: how so that the flame detector detection range at 5m (take candle light as the burning things which may cause a fire disaster standard) in addition, response time short (5ms is following) and rate of false alarm low performance are stable.
The employed technical scheme of the utility model is: a kind of gas flame sensor, the mu balanced circuit that is electrically connected with power supply, the booster converter that is electrically connected with described voltage stabilizing peace road, the photoelectric commutator that is electrically connected with described booster converter, the signal comparator that is electrically connected with described photoelectric commutator, the light alarming device that is electrically connected with described signal comparator and the controller of exporting by electric signal, the outer photosensitive tube of the purple that is electrically connected with described photoelectric commutator.
The beneficial effects of the utility model are: the utility model flame sensor detection range is far away, and the corresponding time is short, and rate of false alarm is low, stable performance.

Embodiment
As shown in Figure 1: a kind of gas flame sensor, the mu balanced circuit that is electrically connected with power supply, the booster converter that is electrically connected with described voltage stabilizing peace road, the photoelectric commutator that is electrically connected with described booster converter, the signal comparator that is electrically connected with described photoelectric commutator, the light alarming device that is electrically connected with described signal comparator and the controller of exporting by electric signal, the outer photosensitive tube of the purple that is electrically connected with described photoelectric commutator.
When the gas in the pipeline was blasted, the outer photosensitive tube of purple can receive flare up fire, by opto-electronic conversion, converts flare up fire to electric signal, and electric signal outputs signal to controller through behind the amplifier.
Employing has the outer photosensitive tube photoelectric conversion mode of two purples, just has signal output when only having two photosensitive tubes that electric signal output is arranged and in conjunction with control circuit after the analytical calculation relatively of control software, to reduce the wrong report of work.
