摘      要

該畢業(yè)設(shè)計(jì)對(duì)環(huán)保、節(jié)能、自動(dòng)補(bǔ)壓型給水設(shè)備作了介紹。從節(jié)能科技的實(shí)踐出發(fā)，闡述了變頻調(diào)速技術(shù)在高樓給水設(shè)備中的應(yīng)用。以PLC電路控制方式，介紹了智能水壓控制系統(tǒng)的工作原理及PLC控制系統(tǒng)。在分析水壓控制的工作流程的基礎(chǔ)上，給出了PLC控制系統(tǒng)的硬件和軟件設(shè)計(jì)。智能水壓控制系統(tǒng)的基本控制策略是：采用電動(dòng)機(jī)調(diào)速裝置與可編程控制器（PLC）構(gòu)成控制系統(tǒng)，進(jìn)行優(yōu)化控制,完成供水壓力的恒定控制，在管網(wǎng)流量變化時(shí)達(dá)到穩(wěn)定供水壓力和節(jié)約電能的目的。系統(tǒng)的控制目標(biāo)是泵站總管的出水壓力，系統(tǒng)設(shè)定的給水壓力值與反饋的總管壓力實(shí)際值進(jìn)行比較，其差值輸入變頻器運(yùn)算處理后，發(fā)出控制指令，控制泵電動(dòng)機(jī)的投運(yùn)臺(tái)數(shù)和運(yùn)行變量泵電動(dòng)機(jī)的轉(zhuǎn)速，從而達(dá)到給水總管壓力穩(wěn)定在設(shè)定的壓力值上。

Abstract
Be graduation practice's turn to have filled up pressure type water supply equipment work to environmental protection , energy conservation , automation introduce that. The frequency conversion speed regulation technology having set off from energy conservation science and technology practice , expounding hits the target in high building water supply equipment applying。Introduced the intelligent hydraulic pressure control system principle of work and the PLC control system. In in the analysis hydraulic pressure control work flow foundation, has produced the PLC control system hardware and the software design. The intelligent hydraulic pressure control system basic control strategy is: Uses the electric motor speeder and the programmable controller (PLC) constitutes the control system, carries on the optimized control,Completes the water supply pressure the constant control, when pipe network current capacity change achieved the stable water supply pressure and saves the electrical energy the goal. The system control goal is the pumping station main pipe water leakage pressure, the system hypothesis carries on the comparison for the hydraulic pressure value and the feedback main pipe pressure actual value, after its interpolation inputs CPU operation processing, sends out the control command, the control pumps the electric motor to throw transports the Taiwan number and the movement variable displacement pump electric motor rotational speed, thus achieved stabilizes for the water main pipe pressure in hypothesis Pressure.
