摘要
针对应用型大学自动化专业人才培养目标,立足培养学生解决复杂工程问题的能力,提出了选用西门子PLC SIMATIC 1214C为主控制器,建试验台,通过在手机终端上的腾讯云远程监控界面发布操作命令,由IOT2050智能网关和物联网平台Node-RED接收指令并下发,实现液压站液位、压力和温度信号采集及调节控制。通过实验测试,基于物联网与PLC的高炉槽下液压站控制系统运行可靠,稳定性好,控制精度高。通过该试验台训练,有效提升学生PLC小型过程控制系统的程序设计与调试、通信组网技术的工程应用能力。
Aiming at the training objectives of automation professionals in application-oriented universities,based on improving students'ability to solve complex engineering problems,it provided the design of the S7-1200 PLC as master,built the test bench.Operation commands were issued through the Tencent Lianlian program on the mobile phone,IOT2050 intelligent gateway and Internet of Things platform Node-Red received instructions and sent.The liquid level,pressure and temperature signals of the hydraulic station werecollected by the SM1234 analog quantity module and the PID command setting was completed.The system temperature was regulated by the heater,the circulating pump was controlled by the frequency converter to regulate the system liquid level,and the system pressure were regulated by the overflow valve.The results show that hydraulic station under blast furnace groove control system based on PLC are reliable operation,high stability and high controller accuracy.Through the training of the test bench,the ability of students'PLC small process control system of program design and debugging and the ability of engineering application of communication networking technology have been effectively improved.
