[0003] In the process of coal mining, it is necessary to detect the concentration of methane and carbon monoxide in the mine at all times. At the same time, combined with the detected temperature and wind speed in the coal mine, a comprehensive analysis is carried out to obtain the environmental safety range of the coal mine, and to further grasp the current environment of the coal mine and avoid There are dangers such as explosion and poisoning, but now, coal mine safety detection usually uses multiple single sensors with different functions for detection. The sensor has a single function and the detection is not comprehensive, so it is not suitable for use in coal mines

Abstract
The invention discloses a multifunctional sensor. The multifunctional sensor comprises a sensor box, a display, a single-chip microcomputer and a detection center; the sensor box is connected with a wind speed sensor, a temperature sensor, a methane sensor, a carbon monoxide sensor, an oxygen sensor, a carbon dioxide sensor, a hydrogen sulfide sensor and a sulfur dioxide sensor which are arrangedoutside through leads; the sensor box is in real-time communication with the detection center through a mining communication cable; and the sensor box further comprises a display, a broadcast device,an alarm button, an audible and visual alarm, a signal processing module, a signal amplification circuit, a single-chip microcomputer and a clock module. The multifunctional sensor disclosed by the invention is comprehensive in detection range and diverse in function; data can be transmitted to the detection center for comprehensive analysis; the audible and visual alarm can be immediately controlled to give an audible and visual alarm once a numerical value is about to reach a critical point of a safe range; and the environmental numerical value at the time can be regularly read and is broadcast through the broadcast device, so that workers can timely know the environmental numerical value of coal mine at the time, and perform reasonable mining according to the change of the environmentalnumerical value.
Description
technical field [0001] The invention relates to the technical field of sensor detection, in particular to a multifunctional sensor. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, which are generally divided into underground coal mines and open-pit coal mines; When the distance to the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine; most coal mines in my country belong to underground coal mines; the scope of coal mines includes a large area above and below ground and related facilities; The reasonable space excavated when the geological layer is rich in coal usually includes roadways, shafts and mining faces, etc. [0003] In the process of coal mining, it is necessary to detect the concentration of methane and carbon monoxide in the mine at all times. At the same time, combined with the detected temperature and wind sp...
