Embodiment Construction

[0016] The safety explosion-proof infrared monitoring system for mine inclined lane transportation of the present invention is designed according to the change principle of infrared wavelength and temperature. In nature, any object higher than the absolute temperature (-273 degrees) will produce an infrared spectrum. Objects at different temperatures release different infrared energy and wavelengths, while the infrared wavelengths released by the human body are 7-10 μm .

[0017] The explosion-proof infrared monitoring system for mine inclined roadway transportation safety is divided into two parts: one part is a passive infrared detection system; the other part is a winch control system, which makes the winch activation device self-lock when there are miners in the roadway.

[0018] The monitoring system specifically includes an infrared detector 1, a signal receiving unit 4, a signal processing unit 5, a relay module group 6 for industrial control of transportation equipment...

Abstract

A safe monitoring protective system for human and vehicles in slanting mine laneway that comprise the infrared detector, the signal gatherable module which connect with the infrared detector by the data electric cable, the signal processing module which connect with the signal gatherable module by the data electric cable, and the relay module which operate and control the transportationed equipments in the laneway. The infrared detector comprise PIR sensor which can translate the wavelength 7 to 12 um of infrared signal into electric signal and can inhibit the nature white light, and lens equipment which can divide the cautionary area into some bright areas and dark areas and refract or reflect the pyroelectric infrared signal to sensor.

Description

technical field [0001] The invention relates to an infrared monitoring system, in particular to an explosion-proof infrared monitoring system for mine inclined lane transportation safety. Background technique [0002] Coal mining and transportation are inseparable from inclined shafts, inclined lanes, and transportation devices. However, due to the complex natural conditions and geological structure, the coal seam roadway is undulating, causing many mine track roadway slopes to be too large, which brings great difficulties to the inclined roadway transportation. According to statistics, among various major accidents in coal mines across the country, accidents of coal trucks breaking ropes and sports cars in inclined lane transportation account for a large proportion. If there are miners staying in the inclined lane, the above-mentioned accidents may endanger the life safety of the miners, and even lead to vicious accidents. [0003] The occurrence of the above-mentioned ac...
