Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.Following examples for illustration of the present invention, but can not be used for limiting the scope of the invention.
Fig. 1 is a kind of structural representation detecting the lighting device for cable channel of hazardous gas of a preferred embodiment of the present invention; Fig. 2 is a kind of modular structure schematic diagram detecting the lighting device for cable channel of hazardous gas of a preferred embodiment of the present invention; The inventive system comprises illumination front deck 1, passage 2, buzzer 3, threshold value setting plectrum 5, switch 6, LED 7 and battery flat 8.
Have threshold value setting module, comparison circuit module, LED driver module, buzzer driver module, lighting module and logic sum gate module in described illumination front deck 1, there is sensor assembly described passage 2 inside; Described sensor assembly, described threshold value setting module, described comparison circuit module composition hazardous gas detection module; Described LED driver module, described buzzer driver module form alarm module.Illumination front deck 1 adopts the LED of high brightness.
Described sensor assembly and described threshold value setting module all connect the signal input part of described comparison circuit module, and the signal output part of described comparison circuit module connects the input of described logic sum gate module; The output of described logic sum gate module connects the signal input part of described LED driver module, the signal input part of described buzzer driver module, the output of described LED driver module connects described LED 7 and lighting module, and the output of described buzzer driver module connects buzzer 3; Described threshold value setting plectrum 5 connects described threshold value setting module, and described switch 6 switches on and off the battery in battery flat 8.
Described device also comprises control panel 4, and described switch 6 is positioned on described control panel 4; Described threshold value setting plectrum 5 is positioned on control panel 4.Described hazardous gas detection module at least 1, when unnecessary one, all connect described logic sum gate module, in the present embodiment, hazardous gas detection module is 3, the hazardous gas detection module of the hazardous gas detection module of hydrogen sulfide, the hazardous gas detection module of carbon monoxide and methane respectively, these three detection modules are all connected with the input of logic sum gate module, hazardous gas detection module detects and judges whether hazardous gas concentration exceeds the threshold value of setting, if exceed threshold value, drives alarm module to send warning.Lighting module provides illumination independent of other module in charge.
High power lithium battery is used in battery flat 8, chargeable, make device intensive.LED 7 selection can show green and redness can organize parallel connection more, safe and reliable to ensure display.Commercially available prod selected by buzzer 3, control panel 4, threshold value setting plectrum 5, switch 6, and its breaker in middle 6 selects multichannel press button, the brightness of illumination of changeable lighting module.The lighting module of illumination front deck 1 adopts highlighted LED to ensure brightness of illumination.Hydrogen sulfide sensor, carbon monoxide transducer, methane transducer select solid metal oxide semiconductor transducer, ensure Measurement reliability and device volume.
