基于S7-1200的自动采样系统设计
|
摘要
针对目前煤炭采样的工艺流程,设计了一款基于S7-1200控制器的自动采样系统,详细介绍了控制系统组成、控制系统软件和硬件设计,对采样系统中可能出现的异常情况提出了检测方法 ,并做了相应的控制。另外还采用上位机实时监测各步工艺流程状态。实际使用证明该自动采样系统可靠性高。
In this paper, an automatic sampling system is designed according to the common process flow based on S7-1200 programable logic controller. It introduces the structure of the control system, software hardware design and for the abnormal condition occurred in the sampling processing, it also designs effective method to detect the fault and then proposes effective control method to protect the device. In addition, the system uses computer to monitor the state of the process. The actual application approves that the automatic sampling system is reliable.
