Experimental method for intelligent detection of poisonous and harmful gas alarm equipment and device thereof

Abstract

The invention discloses an experimental method for intelligent detection of poisonous and harmful gas alarm equipment and a device thereof. Different raw material gases enter a mixer after passing through a high-pressure valve, a pressure gauge, a pressure-reducing valve and a mass flow controller respectively; a gas output from the mixer enters a detected instrument through a flow meter. The mass flow controller is controlled through a computer program to blend needed gases with different concentrations; and sound and image output signals of the detected instrument are input into a computer through an image acquisition and recognition device and a sound level meter, analyzed and calculated by a program and printed and output. Fully automatic detection and report generation of the poisonous and harmful gas alarm equipment are realized by applying computer technology, so the working efficiency of detection is improved. More importantly, the method can greatly enhance the reliability and correctness of detection work, reduce personal error and lower the possibility of contacting poisonous and harmful gases by workers. A metering detection regulation can also be completed according to a detection means.

Description

1. Technical field [0001] The invention relates to the detection of an alarm instrument, in particular to an experimental method and a device for detecting a poisonous and harmful gas alarm. 2. Background technology [0002] At present, the ventilation, ventilation, and readings in the detection of toxic and harmful gas alarms are all done manually, which is time-consuming and laborious, and it is difficult to ensure the accuracy and reliability of the detection results. If it is to test the stability of the instrument, a lot of repetitive labor is required. A small number of intelligent detection experimental devices for toxic and harmful gas alarms abroad are mainly for the purpose of product factory inspection, and the functions are not comprehensive enough. Although there are intelligent product applications in China, their functions are limited to the switching of gas circuits and are limited to manual operation. There are also intelligent dynamic gas distribution dev...

AI Technical Summary

Problems solved by technology

The few foreign toxic and harmful gas alarm intelligent detection experimental devices are mainly for the purpose of product factory inspection, and the functions are not comprehensive enough.

Although there are intelligent product applications in China, their functions are limited to the switching of gas circuits, and are limited to manual operation

There are also intelligent dynamic gas distribution devices used in gas dilution, etc., which are limited to the automation of dynamic gas distribution, without the function of detection and control
