平臺的數(shù)據(jù)處理系統(tǒng)
ARM-Linux 平臺是指利用開源的Linux內(nèi)核經(jīng)過特定需求的裁剪后，經(jīng)過交叉編譯后得到一個能夠運行在ARM處理器的Linux內(nèi)核，同時還定制一個Linux根文件系統(tǒng)，整個系統(tǒng)容量控制在幾百KB到幾十MB。系統(tǒng)主要由三部分組成：BootLoader、ARM-Linux內(nèi)核、Linux根文件系統(tǒng)。
在嵌入式設備上，主要的數(shù)據(jù)處理系統(tǒng)由守護程序實現(xiàn)。守護程序一方面負責接收處理單片機發(fā)送過來的信息;一方面接受WEB服務器傳來的查詢控制請求。
在物聯(lián)網(wǎng)服務器端，來自客戶端訪問的請求，由服務器接收并檢驗后，將請求查詢、控制指令傳遞給守護程序，守護程序接收到來自服務器的請求，通過驗證后再向單片機發(fā)送請求查詢、控制指令。
守護程序的通信過程分為兩部分，第一部分為守護程序向服務端的CGI程序告知更新數(shù)據(jù)，第二部分為服務端CGI程序向守護程序發(fā)送指令控制，由守護程序監(jiān)聽到后執(zhí)行控制程序。
