概述 1982年,曼克赛克(MECSEK)煤矿研究所向匈牙利中央采矿研究院(KBFI)订购了一台旨在开发研究安全用的便携式测量系统。可靠地测量矿山开拓的物理参数,诸如岩石压力、温度、甲烷的涌出量及其压力、顶板下沉等,并且大量采集和处理所测得的数据,就可以用数理统计法来控制、分析和予报岩石的活动。便携式本安型数据采集装置由COSMAC系列CMOS电路微处理机组成。它能够接收、转换和显示串联或并联连接的传感器的直流或交
Overview In 1982, the MECSEK Coal Mine Institute ordered a portable measuring system from the Hungarian Central Mining Research Institute (KBFI) to develop safety-related research. Reliable measurements of the physical parameters of mine development, such as rock pressure, temperature, methane emission and pressure, roof subsidence, etc., and the extensive collection and processing of measured data, can be controlled and analyzed using mathematical statistics And to report rock activity. Portable intrinsically safe data acquisition device consists of COSMAC series of CMOS circuit microprocessor. It is capable of receiving, converting and displaying DC or AC power from sensors connected in series or in parallel
