Problems solved by technology

For areas with a lot of mining production, the calibration workload of this instrument is very large, and because the sensor of the instrument needs to be exposed to air with different proportions of gas, methane or CO during the calibration, the calibration time is very long. Long; although the calibration is carried out on a calibration platform with a ventilation device, this gas will inevitably leak out, and even cause the calibration personnel to be surrounded by this harmful gas for a long time, which will cause serious damage to the health of the instrument calibration personnel. certain threat

Embodiment Construction

[0009] When using this tester, the tester puts the instrument under test into the box body 4 through the front door 6 of the box body 4, then adjusts the vertical beam fastening screw 10 to move the CCD 13 up and down, and adjusts the horizontal fastening screw 8 to move the CCD bracket laterally 12. Align the CCD13 with the display part of the instrument under test, then lock the vertical beam fastening screw 10 and the horizontal fastening screw 8, close the upper cover 7 and the front door 6, and the mixed gases of different proportions enter from the air inlet in turn, It is drawn out from the gas outlet to keep different proportions of gas in the casing 4 . When the mixed gases of different proportions enter the box 4 sequentially, the industrial computer 3 controls the CCD 13 to take pictures of the display part of the instrument under test, and automatically recognizes the data and saves them to verify the accuracy of the instrument under test.

Abstract

The invention relates to an intrinsic safety meter detection instrument with machine vision. By adopting the following technical scheme, a CCD (Charge Coupled Device) and an industrial personal computer are arranged in a box body, one end of the industrial personal computer is connected with the CCD, the other end of the industrial personal computer is connected with a display, the industrial personal computer controls the CCD to take a picture for the display part of a detected meter, and automatically recognize and store the data. Exposure in toxic gas environment can be avoided in manual detection through taking photos for the detected instrument through the CCD, and automatic number recognition of the industrial personal computer. The intrinsic safety meter detection instrument with machine vision brings great convenience for the detection work, and guarantees the health of detection personnel.

Description

technical field [0001] The invention relates to a mine detection instrument, in particular to an intrinsically safe detector. Background technique [0002] Intrinsic safety meter refers to the detection instrument used in mining. This instrument can detect the concentration of methane, gas, CO, etc. in the air, and has important applications in the mining of coal mines, iron ores, etc. According to the requirements of the National Quality Inspection Bureau, this instrument must be calibrated once a year to ensure the reliability of the application instrument. For areas with a lot of mining production, the calibration workload of this instrument is very large, and because the sensor of the instrument needs to be exposed to air with different proportions of gas, methane or CO during the calibration, the calibration time is very long. Long; although the calibration is carried out on a calibration platform with a ventilation device, this gas will inevitably leak out, and even ...
