摘要
设计出一种基于C8051F410单片机的多功能智能给水控制器,并详细介绍了系统的软硬件设计。该控制器的硬件由数据采集、人机接口、电机控制和电源等模块组成,利用单片机的ADC模块采集管道压力,同时控制ADC模块的输出,以改变泵的运转速率,从而维持水压的动态稳定。其中,恒压控制算法采用先进的数字PID控制理论,有机地融合了变频调速技术和单片机技术。该系统能够满足一个小区或一栋高楼居民对供水的需求,且具有高性能、高可靠性、低成本、低能耗等特点。
A constant- pressure water supply controller based on C8051F410 Micro Controller Unit（MCU） core is designed,and the design of the system＇s hardware and software are also introduced in detail. The controller consists of several modules,such as data signal collection module, humanmachine interface module, motor control module and power module. The MCU＇s AD module collects the pipeline＇s pressure,and DA module controls speed of the pump, thereby water pressure is kept stably. The control method is PID theory, integrates VF speed and MCU technique. The system can satisfy the inhabitants＇ demands, and has characteristics of high- performance,high- reliability,low-cost and low- energy consumption.
