Abstract
The research topic involved in this thesis comes from cooperation projcect between school and enterprises of one machinery company.The communication network construction,hardware design and software design of continuous batcher wahser’s water cycle’s control system are estated in the topic.Through field debugging,the water cycle’s control system has good control performance and achieves the water and energy conservation. The research of this paper is essential both in economy and engineering.
The paper firstly designs process flow of the water cycle based on resouring and field research,then directs to the overall scheme design of the control system.The topic designs the control system by the use of hardware and software of phoenix.Analyzing the interbus field bus transmission efficiency and fault diagnosis,we constructs the communication network by interbus field bus;With the field bus controller and the programmable controller Phoenix ILC 350 PLC being a hardware development platform carry through the hardware configuration.With Phoenix software PCWORX6.0 being a software development platform carry through the PLC program design.Through upbuilding the liquid level math model and using matlab software to simulation,introducing the control method of liquid level of tank by PID controller and inverter to achieve the purpose of water conservation;discussing the temperature measurement and control methods.With Visu+ being a software development platform ,designing good performance and good practicability monitor interface. Finally,introducing the field debugging method and process amply.
The topic mainly exploit an applied control system with high autoamtion,high dependability,low failure probability ,ease of maintenance and water and energy conservation in order to increase washing efficiency ,enhance producing time and raise the ratio of water and steam reuse. Both theoretic and experimental research demonstrate following conclusions,the control system of water cycle runs stable and realizes the prospective control effect.
