Detailed description of the invention
Below in conjunction with accompanying drawing, a detailed description of the invention of the present utility model is described in detail, it is to be understood that protection domain of the present utility model is not by the restriction of detailed description of the invention.
A kind of coal mine safety monitoring apparatus structure schematic diagram that Fig. 1 provides for this utility model embodiment.As it is shown in figure 1, this safety monitoring device includes: safety helmet 100, processor 200, repeater 300.
Specifically, as it is shown in figure 1, safety helmet 100 is provided with firedamp sensor 101, signal amplifier 102, AD (English is, analogtodigitalconverter) transducer 103 and alarm 104；In actual applications, firedamp sensor 101 electrically connects with signal amplifier 102, and multiple signal amplifiers 102 all electrically connect with converter 103；Further, converter 103 and processor 200 electrically connect.
It should be noted that electrically connecting between above-mentioned converter 103 and processor 200, including being directly connected to or being indirectly connected with, and include inductively etc.
Specifically, time between converter 103 and processor 200 for being directly connected to, processor 200 is also provided on safety helmet 100, and the particular location that processor 200 is arranged on safety helmet 100 does not limit；Time between converter 103 and processor 200 for being indirectly connected with, processor 200 can arrange in working clothing pocket, in actual applications, processor in order to avoid being arranged in pocket affects miner's work, preferably, and pocket can be set on the arm of working clothing, and the overall dimensions being sized larger than processor 200 of pocket.
In actual applications, in order to avoid single firedamp sensor 101 breaks down, and affect the normal operation of coal mine safety monitoring device, preferably, the quantity of firedamp sensor 101 includes multiple, and the quantity of signal amplifier 102 also includes individual, and the quantity of firedamp sensor 101 is corresponding with the quantity of signal amplifier 102, i.e. a corresponding signal amplifier 102 of firedamp sensor 101.
