| 摘 要： | 在分析传统工控仪表管理方式的缺点基础上,提出了一套基于RS-485工业现场总线系统的技术改造方案.在主机端构建了系统后台数据库,用VB编写数据采集和处理程序,设计了系统的仿仪表界面;建立了系统硬件电路,按照MODBUS协议实现了RS-485工业现场总线系统的驱动控制,用C语言编写了从机端仿工控仪表的监控程序;自动采集的数据经过加工处理后,能自动存入后台数据库,可以方便地查阅实时教据曲线和历史记录曲线.系统结构较简单,功能较完善,具有一定实用价值. |

| Abstract: | Traditionally,the management of industrial instruments is rather difficult and always complicated.A new program that is based on RS-485 industrial field bus systems is proposed in this paper to improve the management operability.At the host side the system back-end database is established and the interface of imitation instruments is designed.The data acquisition and processing procedures are written in VB.Through the connecting hardware circuit,the drive control can now be realized by the RS-485 industrial... |
