摘　　要：为了监测地下工程岩石开挖过程中声发射的主要参数,如大事件率、总事件率和能率,设计了一种以STC89C58RD+单片机为微控制器的多功能岩体声发射监测仪。该仪器具有三通道同步监测、能够适应多种岩体、大/总事件阈值可调、4 Mbits数据可存储下载、长时间连续监测、能与PC机通信等功能。该仪器已应用于矿山井下监测,并且取得了良好的效果。In order to monitor the main parameters, e.g. , major event rate, total event rate, and the rate of energy, of acoustic emission in rock excavation process of underground engineering projects, the multifunctional monitor that is composed of the STC89C58RD ＋ single chip machine as the mierocontroller for acoustic emission in rock has been designed. The major functions of the instrument include three channel synchronous monitoring ; suitable for a variety of rock ; adjustable thresholds of major event rate and total event rate ; 4 Mbits data storage and download ; continuous monitoring for a long period of time ; and the capability of communication with PC. The instrument has been applied in underground mine monitoring and offering well effects.
