IC697BEM721
基于51單片機(jī)的數(shù)據(jù)采集系統(tǒng)
在物聯(lián)網(wǎng)終端設(shè)備方面，采用51單片機(jī)，通過其豐富的外擴(kuò)接口和溫度傳感器、濕度傳感器，以及LED燈等模塊進(jìn)行連接。在軟件上采用“C語言+驅(qū)動庫”的開發(fā)模式，通過這樣的開發(fā)模式，不僅可以提高開發(fā)效率，還能很好地完成多個(gè)傳感器的信息收集和處理。在連接ARM-Linux嵌入式平臺方面，采用UART 虛擬串口與嵌入式平臺進(jìn)行連接通信。
本系統(tǒng)的基本實(shí)現(xiàn)功能如下：
（1）連接各個(gè)傳感模塊，通過輸入輸出接口獲取傳感器傳遞過來的信息并且記錄;
（2）設(shè)置定時(shí)器，在規(guī)定的單元時(shí)間內(nèi)，采集各個(gè)傳感設(shè)備的信息和控制設(shè)備的狀態(tài)。將他們的信息、狀態(tài)合成數(shù)據(jù)包，通過虛擬串口發(fā)送;
（3）利通虛擬串口通信，時(shí)刻檢測來自ARM-Linux平臺發(fā)送過來的控制信號;
（4）分析串口傳遞過來的數(shù)據(jù)包，檢測數(shù)據(jù)來源確定是否合法，然后根據(jù)特定的控制代碼對單片機(jī)和各個(gè)控制模塊進(jìn)行控制。
