全量程甲烷测量仪

Full Range CH4 Surveying Meter

介绍了设计矿用全量程甲烷测量仪的原理及硬件、软件组成，该仪器测量甲烷浓度范围为０～１００％。由于采用了新型单片机ＰＩＣ１６Ｃ５７和使用Ｉ２ＣＢＵＳ等串行Ｉ／Ｏ技术，使整机硬件结构得到简化。软件对热导元件非线性进行校正，提高了测量精度。

This article introduces the principle and formation of hardwares and softwares of Full Range CH4 Surveying Meter used in mines.This kind of instrument can survey CH4 density ranging from zero to 100 percent.D to the adoption of the new- type chip computer PIC16C57 and I2CBOS series connection I/O technique,the meter,s revising the non- linearity of the heat conductive element,the surveying result become more accurate.
