Abstract

The invention discloses a digital display device for a measured value of a light interference type methane measuring device. The digital display device comprises an image sensor, an image processing module, a data processing module and a display module, the image sensor collects interference fringes in the light interference type methane sensor and a high-definition reduction image of the dividing ruler; and the image processing module optimizes and beautifies the acquired image, so that a technician can see the amplified, clear, beautiful and easily-read fringes and the image of the dividing ruler through the display module, and the processed fringes digitally display the measured value of the interference fringes through the data processing module in a preset reading mode. The invention further provides a measuring method of the light interference type methane measuring device. The beneficial effects of the invention are that the method can effectively avoid indicating value errors and visual errors when a technician uses traditional light to interfere the reading of the methane measuring device and tedious operation of using a micrometer, also protects human eyes, greatly improves the working efficiency, is low in cost, and can be popularized and applied in a large area.

Description

technical field [0001] The invention relates to the field of light interference methane detectors, in particular to a digital display device and a measurement method for the measured values ​​of the light interference methane detectors. Background technique [0002] When using an optical interferometric methane detector for methane concentration measurement and verification, technicians still use the human eye to actively identify the interference fringe spectral offset to read the methane concentration value, and also need to use the micrometer on the detector to measure the fractional part. The reading operation is cumbersome, the work efficiency is extremely low, and the test results are easily affected by human operations, and the human eye directly observes the interference fringe readings, which is easily fatigued and affects vision and work efficiency. [0003] There is also a method for converting fringe readings into digital readings in the prior art, but it is more...
