基于三菱PLC控制的恒压供水系统设计样本---硬件与软件设计及运行调试

这是一份关于基于三菱PLC控制的恒压供水系统设计的样本。在国内外的研究现状和系统控制要求的基础上，制定了适用于此恒压供水系统的控制方案。在控制方案中，硬件设计选择了适用的可编程控制器（PLC）型号、变频器型号以及电机泵组的型号，并对系统的输入输出点进行了规划和分配。在软件设计部分，根据控制要求绘制了系统的流程图，并对每个部分的流程图功能进行了解释，使读者能更轻松地了解整个系统的软件设计情况。此外，还采用了MCGS组态软件对控制系统进行监视和模拟运行，直观地再现了现场的实际情况。最后，对整个系统进行了运行调试，运行结果表明该系统具有水压稳定、硬件组成简单、运行可靠和操作方便等优点。关键词：恒压供水、可编程控制器、变频器、组态软件。Overall, this design is a sample for the constant pressure water supply control system based on Mitsubishi PLC control. Based on the research status and control requirements of the domestic and international systems, a control scheme suitable for this system has been developed. In the hardware design part, the selection of the PLC model, frequency converter model, and motor pump group model was carried out, and the planning and allocation of the system's input and output points were also implemented. In the software design part, the system's flowchart was drawn based on the control requirements, and the functions of each part of the flowchart were explained, making it easier for readers to understand the software design of the entire system. In this project, MCGS configuration software is also used to monitor and simulate the control system, which vividly reproduces the actual on-site situation. Finally, the entire system was operated and debugged, and the results showed that the system has the advantages of stable water pressure, simple hardware composition, reliable operation, and convenient operation. Keywords: constant pressure water supply, programmable controller, frequency converter, configuration software.
