1 概述 SH8/8井下数据采集仪是用于煤矿井下本质安全型的智能化数据采集仪器。现主要用于回采工作面综采液压支架的工况监测和矿山压力的观测、数据处理方面。以往使用的连续观测仪器,如用得比较普遍的圆盘自记仪等,数据采集和处理大多数依靠人工或机械半自动方式进行,数据的处理和分析工作非常繁琐,效率低且易出现误差。为改进 1 Overview SH8 / 8 underground data acquisition instrument is used in coal mine intrinsically safe intelligent data acquisition instruments. Now mainly used for working face fully mechanized mining hydraulic support monitoring and pressure monitoring, data processing. The continuous observation instruments used in the past, such as the more commonly used disc self-recording instrument, etc., most of the data acquisition and processing rely on artificial or mechanical semi-automatic way, the data processing and analysis is very cumbersome, inefficient and prone to error. For improvement
