1 概述GJQ-Ⅱ工程机械监测器是针对工程机械没有摩托计时器,无法准确记录机械运行状态各项参数,影响机械设备的正常使用、维护、管理而研制的智能型电子监测仪器。该仪器是采用先进的单片微机系统及IC芯片构成监测和记忆储存数据的智能仪表。1989年4月研制出第一批样机,交济南军区工兵某团试用,经过近半年的使用,达到了设计要求。由济南市公用事业科学研究所和济南军 1 Overview GJQ-Ⅱ Construction Machinery Monitor is aiming at the intelligent electronic monitoring instrument developed by engineering machinery without motor timer, unable to accurately record the parameters of mechanical operation state, affecting the normal use, maintenance and management of machinery and equipment. The instrument is the use of advanced single-chip microcomputer systems and IC chips form a monitoring and memory data storage smart meter. In April 1989, the first batch of prototypes was developed and submitted to a military regiment of Jinan Military Region for trial. After nearly six months of use, the design requirements were met.
