There is a quite many means to integrate fieldbus technology into dcs , while this design emphasizes particularly on providing communication ability between operator station and field instruments , the same time reserving the advanced control and monitor function of the original dcs 然而將現(xiàn)場(chǎng)總線與dcs進(jìn)行集成的方法有多種,側(cè)重點(diǎn)也各有不同。本設(shè)計(jì)則著重解決在保留原有控制系統(tǒng)豐富的監(jiān)測(cè)、控制、協(xié)調(diào)管理功能的基礎(chǔ)上,如何實(shí)現(xiàn)上位機(jī)與現(xiàn)場(chǎng)儀表通信的問(wèn)題。
In this paper , the author gives a detailed introduction of an interface circuit board and a support software both based on hart communication protocol and serial interface communication protocol . the hardware and software together play a key role in the communication between operator station and field instruments 接口卡件能夠在嵌入原來(lái)的國(guó)產(chǎn)分散控制系統(tǒng)supmax500并且不影響其對(duì)遠(yuǎn)程儀表的模擬量進(jìn)行控制的基礎(chǔ)上,支持符合hart協(xié)議的智能儀表與dcs中的分散處理單元和上位機(jī)進(jìn)行通信。
The finished interface circuit board and support software with the unfinished instruments management software running in operator station make up of the socalled remote management system of field instruments which will enhance the ability of dcs , improve the synthesized automation level of the whole system and competition capacity of enterprises Hart接口卡件及相關(guān)軟件已通過(guò)初期的調(diào)試,基本上實(shí)現(xiàn)了預(yù)定的功能。本課題的工作為實(shí)現(xiàn)hart現(xiàn)場(chǎng)總線與supmax500的集成打下了堅(jiān)實(shí)的基礎(chǔ)、成功地邁出了第一步,具有一定的開(kāi)創(chuàng)性和實(shí)用價(jià)值。
