Problems solved by technology

When there is a high-temperature fire source and the oxygen concentration is too high, gas explosions are prone to occur, and when the oxygen concentration is too low, it will pose a threat to the life safety of the staff
At present, the existing oxygen sensors have poor sensitivity and stability, short working hours, and are not suitable for mining in mines. At the same time, the detection range of dangerous gases is relatively small, which reduces the safety performance to a certain extent.

Abstract

The invention relates to a GYH25oxygen sensor for a mine. The oxygen sensor comprises a shell and an oxygen monitoring device. A handle is arranged on the shell. The shell comprises an upper shell body and a lower shell body. The upper shell body and the lower shell body are connected through a supporting arm. The upper shell body is provided with a display window and an alarm window. The lower shell body comprises a sensor containing cavity and gas monitoring cavities arranged on the two sides of the sensor containing cavity. The oxygen monitoring device comprises a battery, an oxygen sensor body, a signal converter, a signal amplifier, a filter, a data collecting card, a data storage, a CPU, a nixie tube displayer, a single-chip microcomputer, an alarm device, a wireless transmission module, an internet and a remote monitoring host. According to the method, an electronic device in the electro-chemistry principle, intelligently controlled through an embedded controller and carrying out displaying through a nixie tube is adopted, operation is easy, use is convenient, the oxygen sensor is safe and reliable and is mainly used for oxygen detection and alarm, and the oxygen detection range can reach 0-25%O2.

Description

technical field [0001] The invention relates to a gas detector, in particular to a GYH25 oxygen sensor for coal mines. Background technique [0002] The working environment in underground mines is harsh, and there is a large amount of gas, which not only affects the health of workers, but also easily affects working equipment and may cause safety accidents. Gas usually exists in the coal body in a free state and an adsorbed state, and is in a state of constant change. After the coal body is mined and in the subsequent transportation and washing process, with the destruction of the coal body structure and the change of the environment, the gas in the coal body will continuously escape into the air. When it is large, it will produce gas accumulation. When there is a high-temperature fire source and the oxygen concentration is too high, a gas explosion is prone to occur, and when the oxygen concentration is too low, it will threaten the life safety of the staff. At present, ...
