The invention relates to an intelligent variable-flow variable-pressure anti-flooding mute secondary water supply system and method based on the Internet of Things. A plurality of Internet of Things pressure sensors collect pressure data of all water supply tail ends of a water supply pipe network respectively; the edge computing gateway computes the tail end minimum pressure Fm and sends the tail end minimum pressure Fm to the anti-flooding mute frequency converter of the Internet of Things; the water outlet pressure sensor collects the outlet pressure Fck of the Internet of Things anti-flooding mute pump set; setting feedback pressure Ff = Fm and target pressure Fs = Fmm, or setting feedback pressure Ff = Fck and target pressure Fs = Fmc; according to the feedback pressure and the target pressure, the output frequency of the internet-of-things anti-flooding mute frequency converter is adjusted through a PID control algorithm, the operation speed of an anti-flooding mute pump is controlled, and the water outlet pressure is adjusted; by adopting the mode of constant pressure at the tail end and variable pressure and variable flow at the outlet, the water outlet pressure can be automatically adjusted according to the actual use water quantity, and when the water outlet flow is very small or zero, the water outlet pressure is automatically reduced or the equipment is directly shut down, so that the energy consumption value of the secondary water supply equipment is greatly reduced.
本发明涉及一种基于物联网的智能变流变压防淹静音二次供水系统及方法，多个物联网压力传感器分别采集供水管网各个供水末端压力数据；边缘计算网关计算末端最小压力Fm发送给物联网防淹静音变频器；出水压力传感器采集物联网防淹静音泵组的出口压力Fck；设定反馈压力Ff＝Fm且目标压力Fs＝Fmm，或反馈压力Ff＝Fck且目标压力Fs＝Fmc；物联网防淹静音变频器根据反馈压力和目标压力，采用PID控制算法调节物联网防淹静音变频器的输出频率，控制防淹静音泵的运转速度调节出水压力；采用末端恒压、出口变压变流的方式，能根据实际使用水量自动调节出水压力，当出水流量很小或为零时，自动降低出水压力或者直接设备停机，大大降低二次供水设备的能耗值。
