Embodiment Construction

[0067] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.

[0068] Such as figure 1 As shown, the wide-concentration multi-component dangerous gas detector provided by the present invention has simple structure, scientific and reasonable design, and is easy to use. At the same time, the gas dilution sampling joint can dilute high-concentration dangerous gases, prevent electrochemical sensor poisoning, and effectively broaden the gas detection concentration range. The sensor integration module is equipped with multiple unit gas chambers, and each unit gas chamber can Distribute an electrochemical sensor to detect a dangerous gas. It can detect up to 8 kinds of dangerous gases, including HCN, HCl, SO 2 , NO 2 , CO, NO, H 2 Dangerous gases such as S have a wide range of gas detection, and the sampling results are processed b...

Abstract

The invention discloses a wide-concentration multi-component hazardous gas detector and an implementation method thereof, and solves the problems that a gas detector equipped by fire forces in the prior art often has false negative detection results, over-limit concentration and sensor poisoning conditions. The wide-concentration multi-component hazardous gas detector comprises a gas dilution sampling joint, a sensor integration module, an electrochemical sensor, an ADC circuit, an MCU single chip microcomputer, an audible and visual alarm, a 4-key keyboard module, an LED display module, an SD card data storage module, a power control and electric quantity display module, a high-performance lithium battery pack, a small air pump, a 433M signal transmission module and a remote command platform signal acquisition terminal. The implementation method provided by the invention is simple, smooth and efficient, can effectively prevent the poisoning and the misinformation of the electrochemical sensor, can detect various gases, and is wide in gas detection concentration range and accurate in detection result.

Description

technical field [0001] The invention relates to a wide-concentration multi-component dangerous gas detector and a realization method thereof. Background technique [0002] At present, the most commonly used dangerous gas detection equipment for fire brigade mainly includes four-in-one gas detector and combustible gas detector. The 4-in-1 gas detector is suitable for on-site detection in various places such as chemical industry, petrochemical industry, coal and municipal gas, etc. It can meet the measurement needs of special occasions, and perform gas concentration detection or leakage detection on tunnels, pipelines, tanks, and sealed windows. The combustible gas detector is a general-purpose detection instrument used to detect and measure a variety of dangerous gases. It is suitable for detecting toxic and corrosive gases in temporary occasions, and has the characteristics of easy operation. [0003] However, the portable gas instruments sold in the market and equipped by ...
