毕业设计说明书(论文)中文摘要
随着城市化的进一步发展和城市高层建筑的增多,二次供水的应用范围 越来越广泛,市场对二次供水设备的需求量不断上升。同时二次供水设备的 节能标准也在不断提高,市场对二次供水设备的进入门槛越来越高,如何节 能降耗成为研发二次供水设备时的重要考量因素。增压流量配比系统是二次 供水的重要组成设备,研发新型智能型增压流量配比柔性控制系统对于进一 步提高二次供水设备性能、降低二次供水能耗具有重要意义。 本设计是根据合作企业提高产品竞争力、开拓市场的需要,提出了以微 控制器STM32F103VET6(ARM CM3核)为核心的流量配比控制单元控制器方案,其ARM机一方面通过RS485总线接收PLC上位机的控制指令,另一方面接收差 压流量传感器的流量信号并控制无刷直流电机调节阀门开度,达到精确控制 流量的目的。本文从增压流量配比控制系统的总体设计和软硬件设计入手, 详细阐述了该控制器设计的思路、原理和解决方案等。最后对方案提出了一 些改进的意见。 关键词:二次供水 流量配比控制 STM32F103VET6 RS485 无刷直流电机

Title The Design of the Flexible Flow Proportioning Controller in Pressurize Water Supply Abstract With the development of the urbanization and the increase of high-rise buildings in cities, the applied range of secondary water supply now becomes more and more extensive and the demand to the secondary water supply equipments is on the increase. At the same time, the energy conservation standard and the admittance standard of the secondary water supply equipments is also upgraded. How to save energy becomes the important consideration factor in designing the secondary water supply equipments. Flow proportioning system is the important part in secondary water supply equipment. So the designing of the new intelligent flow proportioning controller in pressurize water supply is of great significance to raise the characteristics and reduce the energy consumption of the secondary water supply equipments. Our design is based on the co-operative enterprise’s demand to raise the competitive power and open up the market of their products. We bring forward a plan whose core is the MCU of the STM32F103VET6. On the one hand the ARM MCU receives signals from the PLC upper monitor, on the other hand it receives flow signals from the flow sensors and drives the motor to change the opening of the valve. So we can control the size of the flow accurately. My thesis is written based on the
