单片机控制的全自动变频调速恒压供水系统的研制

THE DESIGN OF THE FULL AUTOMATIC FREQUENCYCHANGING SPEED CONTROL OF UNCHANGED TENSION WATER SUPPLY DEVICE BASED ON SINGLE CHIP MICROCOMPUTER CONTROL

本文研究了变频调速器及电动阀的单片机控制电路及电气控制电路，讨论了单片机的软件编程．由本文电路构成的恒压供水装置．已做成一体化控制柜，在供水现场实际运行表明，该装置的可靠性高，其硬件、软件均有较强的抗干扰能力和保护功能．

This peper dials with single chip microcomputer control cirCuit and electic control circuit of inverter and eleCtric valve. It disscusses aboUt the software and program of single chip micro comPUter. The unchanged tension water supply device is made from the circuits of this paper, and has worked for two you in a water supply factory, and has not appeared any fault. It shows that the software and the hardware have strong function of Protection and interference rejection.
