Abstract: To against the problem of lowering energy consumption and maintenance cost in water supplying enterprises, a DSP based frequency conversion automatic constant-pressure water supplying system is designed. Three large power water pumps are controlled by TMS320F149 DSP and one 160 kW large power frequency converter. Thus constant-pressure water supplying is implemented for certain water works. The hardware composition and DSP programming principle are analyzed in detail. The experimental operation shows that the system is stably running with precise pressure control and excellent economical effects.
