Abstract

The invention discloses a mining alarm. The mining alarm comprises a direct-current control circuit, an alternating-current control circuit, a singlechip, a function selection switch, an intrinsic safety power supply and a power supply, wherein the direct-current control circuit sends a direct-current trigger signal to the singlechip; the alternating-current control circuit sends an alternating-current trigger signal to the singlechip; the singlechip controls an audible and visual alarm circuit to perform audible and visual alarm according to the direct-current trigger signal or the alternating-current trigger signal; a plurality of different voice alarm contents are preset in the audible and visual alarm circuit; the function selection switch is used for providing a function of selecting one of the plurality of different voice alarm contents; the intrinsic safety power supply is used for converting 36-volt or 127-volt alternating-current power into 12-volt direct-current power; and the power supply is used for converting the 12-volt direct-current power into 5-volt direct-current power and supplying the power to the singlechip and the audible and visual alarm circuit. Therefore, by the mining alarm two alarm modes of voice and light can be realized; the voice alarm contents can be selected; and the mining alarm has various functions.

Description

technical field [0001] The invention relates to an alarm device, in particular to a mine alarm. Background technique [0002] The mine alarm is a kind of mine security equipment, which is often installed on the front of the mine car. It is used in the occasions such as track deviation, damper, inclined shaft winch and loading and unloading yards where there is a risk of gas and coal dust explosion in the coal mine. . When the mine car passes through various openings, curves, or getting on and off the track slope of the coal mine along the track, the driver of the mine car will power on the mine alarm, and the mine alarm will send out an alarm signal to remind the nearby staff to avoid Pay attention to safety when driving the mine car. After the mine car passes the above-mentioned places, the driver of the mine car will turn off the power, and the mine alarm will stop alarming. Yet known mine alarm function is single at present. Contents of the invention [0003] The pur...
