Abstract
The utility model discloses an ultraviolet light smoke sensor, aiming at being capable of accurately measuring the smoke concentration value in a coal mine. The ultraviolet light smoke sensor comprises a handle, a light alarm, a sound alarm, a connecting plug, a display, a shell, a collection head assembly, a sensillum acquisition bin, a circuit board and a GaN ultraviolet light detector, wherein the GaN ultraviolet light detector is positioned below the sensor.
Description
Technical field
The utility model relates to a kind of mining smoke transducer, specifically is the ultraviolet light smoke transducer.
Background technology
What existing smoke transducer adopted all is traditional ionic formula metering system, and in actual use, reflection is slow, poor sensitivity, and wrong report easily, and can only differentiate the situation whether smog is arranged, can't measure its smokescope value accurately.
The utility model content
In order to overcome the deficiencies in the prior art, provide a kind of ultraviolet light smoke transducer that can accurately measure smokescope value in the colliery.
The utility model comprises handle, light warning, acoustic alarm, connection plug, display, shell, collection head assembly, circuit board, GaN ultraviolet light detector, smog collection storehouse, the collection head assembly is mainly gathered the storehouse by GaN ultraviolet light detector and smog and is constituted, the GaN ultraviolet light detector is fixed on gathers in the storehouse, it is positioned at the below of sensor, and the GaN ultraviolet light detector has the ultraviolet light pipe and the ultraviolet receiving tube of fixed band.
Description of drawings
Figure one is a ultraviolet light smoke transducer structural drawing
Figure two is the vertical sectional drawing of ultraviolet light smoke transducer
Figure three is a ultraviolet light smoke transducer principle of work synoptic diagram
Among the figure 1, handle, 2, light report to the police, 3, acoustic alarm, 4, connection plug, 5, display, 6, shell, 7, the collection head assembly, 8, circuit board, 9, the GaN ultraviolet light detector, 10, smog gathers the storehouse
Embodiment
See figures.1.and.2, connection plug 4 is received on the power supply, the ultraviolet light smoke transducer is just started working, when smog enters sensor acquisition storehouse 10, can produce the effect of blocking to the ultraviolet light that the ultra-violet light-emitting pipe sends, after receiving the ultraviolet signal of sending when receiving tube, according to the exportable relative voltage signal of its ultraviolet ray intensity, when this voltage signal is transported to single-chip microcomputer on the circuit board 8 after secondary circuit is handled in, by calculating just exportable corresponding smokescope, just can see the data of smokescope from the display 5, surpass setting value as smokescope, light report to the police 2 and acoustic alarm 3 can in time start.
Claims (2)
1. ultraviolet light smoke transducer, it is characterized in that it is made up of handle, light warning, acoustic alarm, connection plug, display, shell, collection head assembly, circuit board, GaN ultraviolet light detector, sensor acquisition storehouse, described GaN ultraviolet light detector is positioned at the below of sensor.
2. ultraviolet light smoke transducer according to claim 1 is characterized in that the GaN ultraviolet light detector has the ultra-violet light-emitting pipe and the ultraviolet light receiving tube of fixed band.
