Embodiment 1

[0032] Embodiment 1: The detection trigger module includes a Hall sensor probe and a Hall sensor sensing patch; the Hall sensor sensing patch is arranged at the light-transmitting part on the turntable, and the data output end of the Hall sensor probe is connected to the controller module; The Hall sensor probe is used to detect the position of the Hall sensor sensor patch, so as to detect the moment when the light-transmitting part passes the Hall sensor probe, and upload the time information to the controller module;

Embodiment 2

[0033] Embodiment 2: The detection trigger module includes a touch switch and a touch block; the touch block is arranged at the light-transmitting part on the turntable, and the data output end of the touch switch is connected to the controller module; the touch switch is used to detect the position of the touch block, Therefore, the time when the light-transmitting part passes the touch switch is detected, and the time information is uploaded to the controller module.

[0034] In specific implementation, the light-transmitting part can be realized by means of light-transmitting holes, light-transmitting grooves, etc., wherein the light-transmitting grooves can adopt arc-shaped grooves (such as figure 1 As shown in ), grooves in other directions (such as the radial direction) can also be used, the purpose of which is to allow the detection laser emitted by the infrared laser methane concentration measuring instrument to be measured to penetrate the turntable.

Abstract

The invention discloses a dynamic response time detection device for an infrared laser methane concentration measuring instrument. The dynamic response time detection device comprises a power module,a standard concentration methane gas chamber, a speed-adjustable motor, a motor control module, a rotating disc, a controller module and a data output module. The power module supplies electricity; the controller module controls the rotating speed of the speed-adjustable motor through the motor control module; measuring laser outputted by the infrared laser methane concentration measuring instrument penetrates a light-permeable portion of the rotating disc to be irradiated to the standard concentration methane gas chamber, and data are uploaded to the controller module after gas concentrationis measured; the controller module outputs received measured data through the data output module; detecting personnel can detect dynamic response time of the infrared laser methane concentration measuring instrument according to detection data. The invention further discloses a method of the dynamic response time detection device for the infrared laser methane concentration measuring instrument. By adoption of the technical scheme, high detection precision, low cost and high reliability are realized.

Description

technical field [0001] The invention specifically relates to a dynamic response time detection device and method of an infrared laser methane concentration measuring instrument. Background technique [0002] With the development of infrared laser measurement technology, more and more laser measurement instruments have been put into use in the market in recent years, bringing endless convenience to people's production and life.
