1、靜電紡絲環(huán)境監(jiān)控系統(tǒng)設(shè)計(jì)I靜電紡絲環(huán)境監(jiān)控系統(tǒng)設(shè)計(jì)靜電紡絲環(huán)境監(jiān)控系統(tǒng)設(shè)計(jì)摘要當(dāng)今納米科技已更廣泛的應(yīng)用于各研究領(lǐng)域，更多的人開(kāi)始關(guān)注制備連續(xù)微納米纖維的靜電紡絲法，靜電紡絲法是通過(guò)高壓靜電發(fā)生器產(chǎn)生的電場(chǎng)力拉伸聚合物溶液或熔體來(lái)制備超細(xì)纖維的重要方法，通過(guò)此方法獲可以得連續(xù)微米級(jí)別以下的超細(xì)纖維，通過(guò)電紡的方法可以制備出多種納米纖維，通過(guò)靜電紡絲方法制備得到的納米纖維，具有較小直徑的納米尺寸，高比表面以及纖維之間形成的微小孔隙[1]。

2、在研究中發(fā)現(xiàn)環(huán)境溫濕度的改變對(duì)纖維直徑及其形態(tài)結(jié)構(gòu)的影響很大，所以在工業(yè)生產(chǎn)中對(duì)其環(huán)境溫濕度相對(duì)恒定的控制具有極大的意義。本系統(tǒng)設(shè)計(jì)了一種基于STM32的溫濕度采集控制系統(tǒng)，該單片機(jī)是一款高性能的32位機(jī)，具有豐富的硬件資源和非常強(qiáng)的抗干擾能力，特別適合構(gòu)成智能測(cè)控儀表和工業(yè)測(cè)控系統(tǒng)。系統(tǒng)以STM32F103RBT6單片機(jī)作為微控制器構(gòu)建數(shù)字溫濕度控制器，通過(guò)溫濕度傳感器采集到的數(shù)據(jù)與規(guī)定數(shù)據(jù)進(jìn)行對(duì)比，完成對(duì)現(xiàn)場(chǎng)設(shè)備的控制，從而保證溫濕
