摘要
介绍了用 850 1单片机控制的变频调速恒压供水系统 ,给出了系统的硬件结构及单片机控制程序框图。在系统中 ,850 1CPU产生三相交流调频控制信号 ,经驱动后 ,输送到逆变主桥路 ,实现恒压调速。
This article explains the constant pressure water supply system by frequency speed control using 8501 chip, give the hardware structure and the diagram programming frame using single-chip microcomputer control. In the system, the control signal of frequency regulation made by 8501 CPU is sent to the main bridge circuit by amplifying so as to vary the speed to remain the constant pressure.
