1、西北工業(yè)人學(xué)碩士學(xué)位論文摘要摘要無損傷抗運動病藥物性能檢測設(shè)備是航天醫(yī)學(xué)中一種必不可少的醫(yī)療儀器,對抗運動病藥物藥效分析有著十分重要的意義。針對傳統(tǒng)醫(yī)療檢測設(shè)備可移動性差,數(shù)據(jù)傳輸電纜不便于人們隨時隨地進(jìn)行實驗研究的缺陷,本文對比研究了各種短距離無線通信技術(shù)和計算機外設(shè)接口,提出了采用藍(lán)牙無線通信技術(shù)和USB接口來取代主控機與下位機之間有線電纜的方案。藍(lán)牙和USB接口技術(shù)是90年代新興的兩個熱門技術(shù),其目的一個是替代設(shè)備間的電纜,一個是支持即插即用。系統(tǒng)把藍(lán)牙無線的自動連接和有線的即插即用USB接口相結(jié)合,很好地解決了旋轉(zhuǎn)動物模型上的數(shù)據(jù)對接問題。本文從
2、藍(lán)牙無線通信和USB接口兩方面闡述了系統(tǒng)實現(xiàn)原理,選用藍(lán)牙射頻和主控制器硬件芯片—NRF2401和CY7C68013,完成了主控PC端無線通信及USB接口系統(tǒng)的軟硬件設(shè)計。系統(tǒng)主要由數(shù)據(jù)無線傳輸、基帶控制和USB通信三部分組成。本文分別論述了系統(tǒng)射頻電路、基帶控制電路、RAM擴展、電源電路的具體設(shè)計,對系統(tǒng)的抗干擾措施進(jìn)行了研究,繪制了PCB。固件采用模塊化編程,分為9個程序文件來實現(xiàn)系統(tǒng)功能。最后對系統(tǒng)進(jìn)行了初步調(diào)試。實踐表明,系統(tǒng)具有成本低、體積小、輻射小和固件容易升級等優(yōu)點。本文研究內(nèi)容是航空科學(xué)基金課題(041153036)和橫向課題(N3EK1
