Abstract
The invention provides a carbon monoxide gas concentration detection alarm instrument, and relates to safety alarm technical field of gas concentration detection. A signal output end of a carbon monoxide gas concentration detection inductive probe is connected on a central processor through a signal processing circuit, the central processor is respectively connected with a work power supply circuit, an alarm circuit and a nixie tube displayer. The alarm instrument has the advantages of compact structure and small volume, and the adopted nixie tube displayer is clearer than a liquid crystal displayer, thereby the alarm instrument is being capable of leading people to take in everything at a glance no matter whether outside light is strong or weak.
Description
Technical field
The present invention relates to the safety alarm technical field that gas concentration detects.
Background technology
During borehole operation; Often there is the excessive danger of carbon monoxide gas concentration,, tended to ignore the variation of carbon monoxide gas concentration because people are in this environment for a long time; In case it is too high carbon monoxide gas concentration to occur, will cause the destruction of personal injury and equipment.Mostly through the liquid crystal display carbon monoxide gas concentration, its bright dipping is very faint in the present carbon monoxide gas concentration alarm, and inconvenient people observe, and during if any extraneous strong illumination, can't let the people recognize especially.In addition, existing instrument volume is bigger, is inconvenient to use.
Summary of the invention
The object of the invention is to design the carbon monoxide gas concentration detection alarm appearance that a kind of volume is little, be easy to observe.
The present invention includes carbon monoxide gas concentration and detect inductive probe; The signal output part that carbon monoxide gas concentration detects inductive probe is connected on the central processing unit through signal processing circuit, and said central processing unit also connects working power circuit, warning circuit, charactron display respectively.
The present invention detects inductive probe through carbon monoxide gas concentration and collects the carbon monoxide gas concentration in the environment; Be transformed into the discernible signal of central processing unit through signal processing circuit; Carry out data analysis, contrast by central processing unit, go out then through the charactron display to reflect carbon monoxide gas concentration in real time.Be higher than setting value like carbon monoxide gas concentration, central processing unit starts warning circuit through after the correlation data.Compact conformation of the present invention, volume are little, adopt the charactron display clear than liquid crystal display, no matter extraneous light is strong and weak, can both make people one so undoubtedly.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present invention.
Fig. 2 is circuit theory diagrams of the present invention.
Embodiment
Like Fig. 1, shown in 2; The signal output part that carbon monoxide gas concentration of the present invention detects inductive probe 1 is connected on the central processing unit 3 through signal processing circuit 2, and central processing unit 3 also connects working power circuit 4, warning circuit 5 and charactron display 6 respectively.
Claims (1)
1. carbon monoxide gas concentration detection alarm appearance; Comprise that carbon monoxide gas concentration detects inductive probe; The signal output part that it is characterized in that said carbon monoxide gas concentration detection inductive probe is connected on the central processing unit through signal processing circuit, and said central processing unit also connects working power circuit, warning circuit, charactron display respectively.
