Control method and device for multi-pump parallel water supply unit
The invention discloses a control method and device for a multi-pump parallel water supply unit. In the multi-pump parallel water supply unit, each pump is provided with an integrated permanent magnet synchronous motor, and the integrated permanent magnet synchronous motor integrates a motor, a variable frequency driver, a controller, a human-computer interface and a communication module into a whole; the memory data of a controller of each integrated permanent magnet synchronous motor is logically divided into two parts, one part is a shared data block which stores operation process parameters of the multi-pump parallel water supply unit and the operation state of the unit, and the controller of the integrated permanent magnet synchronous motor of each pump can be read; and the other part is a private data block which is used for storing private data of the local machine and is not shared by other integrated permanent magnet synchronous motors. A new master control pump can be selected only when the master control pump breaks down or communication is interrupted, so that the unnecessary water pump alternation frequency is reduced; control parameter set values can be shared and modified in real time among multiple pumps; all pumps in the unit can adopt different powers and models, and the configuration of the unit is flexible.
本发明公开了一种多泵并联供水机组的控制方法及装置，多泵并联供水机组中,每台泵均安装有一个一体化永磁同步电机，所述一体化永磁同步电机集成电机、变频驱动器、控制器、人机界面和通信模块于一体；每个一体化永磁同步电机的控制器的内存数据逻辑上分为两部分，一部分为共享数据块，存储多泵并联供水机组的运行工艺参数和本机运行状态，各泵的一体化永磁同步电机的控制器均可读取；另一部分为私有数据块，存放本机私有数据，不对其余各一体化永磁同步电机共享。在主控泵发生故障或通信中断时才会选出新的主控泵，减少不必要的水泵轮换次数；控制参数设定值可以在多泵间实时共享修改；机组里的所有泵可以采用不同功率、型号，机组配置灵活。
