【摘要】：針對(duì)物聯(lián)測(cè)控技術(shù)面對(duì)對(duì)象多種多樣以及物聯(lián)網(wǎng)絡(luò)構(gòu)成復(fù)雜、實(shí)時(shí)性低等不足,以片上系統(tǒng)C8051F20為核心,基于FreeModbus協(xié)議設(shè)計(jì)了一種支持多接口、集約化、本機(jī)可編程的智能物聯(lián)終端。終端支持Modbus RTU、Modbus TCP數(shù)據(jù)通信,可與上位機(jī)無縫對(duì)接,實(shí)現(xiàn)遠(yuǎn)程監(jiān)控,又可靈活連接現(xiàn)場(chǎng)傳感器和執(zhí)行器。同時(shí),系統(tǒng)移植了μC/OS-Ⅱ操作系統(tǒng)并采用μC/GUI進(jìn)行用戶界面搭建,軟件中設(shè)計(jì)有邏輯編程功能,實(shí)現(xiàn)了本機(jī)可編程。使終端能同時(shí)進(jìn)行遠(yuǎn)程測(cè)控和現(xiàn)場(chǎng)實(shí)時(shí)邏輯控制,同時(shí)縮減了通信量、降低了網(wǎng)絡(luò)復(fù)雜程度,解決了測(cè)控實(shí)時(shí)性問題。實(shí)際應(yīng)用表明,該終端工作穩(wěn)定可靠,編程操作簡(jiǎn)單,實(shí)時(shí)性好,適應(yīng)性強(qiáng),達(dá)到了實(shí)用要求。
[Abstract]:In view of the shortage of various objects, complex structure and low real-time performance of WMT technology, a kind of multi-interface is designed based on FreeModbus protocol, which is based on C8051F20, which is the system on chip. The terminal supports Modbus RTU Modbus TCP data communication, can connect seamlessly with the upper computer, can realize remote monitoring, and can connect field sensors and actuators flexibly. The system transplanted 渭 C / OS- 鈪，
