為了滿足HIFU【1】【注】醫(yī)療系統(tǒng)要求，在分析常用水溫水位單一控制方式存在問題的基礎(chǔ)上提出了水溫水位智能控制系統(tǒng)。闡述了系統(tǒng)的硬件設(shè)計(jì)、控制方案及原理，并給出了水溫水位控制原理圖和部分軟件流程圖。仿真實(shí)驗(yàn)結(jié)果表明, 采用該系統(tǒng)對水溫水位進(jìn)行控制，取得了良好的效果，而且調(diào)節(jié)過程平穩(wěn)。關(guān)鍵詞：水囊、傳感器、脈寬調(diào)制、比例/積分/微分控制器、智能控制

Aptitude control of medium water temperature and water level in HIFU medical treatment system XU Hui，LIU Feng Abstract: To satisfy HIFU medical treatment system request，an aptitude control system of medium is stated on the basis of analysis of conventional water temperature and water level single control mode and existing problems。The hardware design of system , control project and principle are described emphatically。Then the control principle chart of water temperature and water level，partial program flow chart are given。The emulational experiment result shows that the system adjusts placidly and receives well effect。
