Automatic intrinsic safety meter checking system

Abstract

The invention relates to an automatic intrinsic safety meter checking system. With the adoption of the following technical scheme, a system control module, a machine vision module, an analysis calculation module, a print display module, a TCP (Transmission Control Protocol) / IP (Internet Protocol) module and a data communication module are arranged inside a detection box, wherein the machine vision module, the analysis calculation module, the print display module, the TCP / IP module and the data communication module are connected with the system control module. The automatic intrinsic safety meter checking system further comprises an automatic air distribution device. Under an instruction of the system control module, the automatic air distribution device can configure desired gases with different ratios; the machine vision module reads a number on an intrinsic safety meter; and the data is transmitted to a control handheld box through a WiFi (Wireless Fidelity) module, so that an operator can conduct long-distance control and the automatic reading can be realized, and the checking time is greatly shortened. Meanwhile, the health of the verification personnel can be ensured, so that the automatic intrinsic safety meter checking system brings great convenience to the verification operation.

Description

technical field [0001] The invention belongs to the field of mining detection instruments, and in particular relates to an automatic calibration system for intrinsically safe meters. 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 ventil...

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

Therefore, the calibration of intrinsically safe instruments urgently needs a system that can automatically realize gas distribution and instrument reading to replace manual calibration, but such equipment is currently lacking.
