Abstract

The invention discloses a harmful gas concentration detection device and a detection method. The harmful gas concentration detection device comprises a detection trolley and a control device; the detection trolley is composed of a base, a multi-section telescopic rod and an electric push rod; the telescopic end of the multi-section telescopic rod is fixedly provided with a stepping motor, and the output end of the stepping motor is fixedly connected with a first wireless signal transmission device; according to the gas concentration detection device, the concentration of gas is detected through the gas concentration detection sensor and the vacuum detection cavity, and a real-time and accurate detection result can be obtained; the gas in the sealed cavity is sampled through the sampling element, and a more accurate detection result is obtained through analysis of the detection analyzer; and the detection analyzer is used for comparing two concentration detection results to judge whether the sensor fails or not, so that the situation that wrong concentration information is obtained due to the failure of the sensor is avoided, and the detection result is more accurate.

Description

technical field [0001] The invention relates to the technical field of gas concentration detection, in particular to a gas concentration detection device and a detection method thereof. Background technique [0002] With the rapid development of social economy and the improvement of people's living standards, people pay more and more attention to industrial safety and living environment, so it is more and more important to detect the gas concentration in the environment where people live. Especially in chemical workshops, some products often produce a large amount of gas during production. When these gases reach a certain concentration, they will cause certain harm to the health of the staff, and even threaten the safety of the staff's life. Some irreparable losses are caused, so detecting the gas concentration is an important measure to prevent losses and protect personal safety. [0003] Most of the existing gas detectors are portable and hand-held. This kind of detection...
