rements。 Use of advanced automatic control technology and munication technology, the design of high performance, low energy consumption, widely applied in the constant pressure water supply system bee inevitable trend. In view of the application of constant pressure water supply system, the structure of all kinds of constant pressure water supply system are analyzed, explained the acquisition, control principle of the pressure, based on single chip microputer is given pressure acquisition channel connection diagram.Key words: Constant pressure water supply system。 frequency conversion。 MCU。 Pressure acquisition1 引言變頻調(diào)速恒壓供水具有節(jié)能、自動(dòng)化程度高、操作控制方便等優(yōu)點(diǎn),因而在住宅小區(qū)及高層建筑生活供水系統(tǒng)中的應(yīng)用日益
