Mining comprehensive gas monitoring and early warning system based on optical fiber sensing technology

Abstract

The invention discloses a mining comprehensive gas monitoring and early warning system based on an optical fiber sensing technology. The system comprises a gas chamber, a system terminal and a gas inlet formed in the gas chamber, wherein a laser is mounted in the gas chamber, an infrared sensor is mounted below the laser, and an optical fiber sensor is mounted in the gas chamber on one side of the infrared sensor; a demodulator, a system terminal, a storage battery and an alarm are arranged outside the gas chamber; the optical fiber sensor and the infrared sensor are in signal connection with the demodulator; the demodulator is in signal connection with the system terminal; and the system terminal is in signal connection with the alarm. Through a series of structures, the mining comprehensive gas monitoring and early warning system based on the optical fiber sensing technology can obtain the concentration and the volume of toxic gas in the gas without analyzing by a plurality of sensors, and the system is relatively convenient.

Description

technical field [0001] The invention relates to the technical field of gas monitoring, in particular to a mining comprehensive gas monitoring and early warning system based on optical fiber sensing technology. Background technique [0002] Toxic gases are produced during the blasting construction of mining projects, which cause harm and pollution to the personnel and the environment in the construction area. It is necessary to monitor and warn of toxic gases. Gas detectors, also known as gas detectors, are a kind of gas leakage concentration Instrumentation tools for detection mainly refer to portable / handheld gas detectors, which mainly use gas sensors to detect the types of gases existing in the environment. Gas sensors are sensors used to detect the composition and content of gases. It is generally believed that the gas sensor The definition is based on the detection target, that is to say, any sensor used to detect gas composition and concentration is called a gas sensor...

AI Technical Summary

Problems solved by technology

[0003] At present, the monitoring gas composition is basically a single monitoring sensor. It is cumbersome to install several sensors or take gas samples to the laboratory for analysis if several types of gas content are needed. The geographical environment used by the gas monitoring device is relatively complicated. The equipment is installed in a suitable location, but the installation of the existing monitoring equipment is inconvenient
