摘　　要：针对取样钻机供电系统存在电力参数监测难、采集精度低的问题,提出了一种基于RS-485总线的智能监测系统。重点分析了上位机监控软件的构建和RS-232/RS-485接口转换器的设计,同时介绍了计算机与多功能网络电力仪表AOB192E-9T4的实时通信方式。测试结果表明,该系统具有运行稳定可靠、操作简单方便、响应速度快、抗干扰能力强、高精度等特点,大大简化了系统硬件电路。Aiming at the problems existing in power supply system of sampling drilling machine, such as hard to monitor the electric parameters and low accuracy of acquisition, an intelligent monitoring system based on RS- 485 bus is proposed. The construction of the monitoring software in host computer and the design of RS-232/RS-d85 interfacing converter are analyzed in focus. In addition, the real-time communication between computer and multifunctional networking electric instrument AOB192E-9T4 is introduced. The test results indicate that the system features simplified hardware circuits, stable and reliable running, easy to operate, fast response speed, strong anti-interference capability, and high accuracy, etc.
