DCS工業(yè)PC化：由IPC組成DCS已成為一大趨勢(shì)，PC作為DCS的操作站或節(jié)點(diǎn)機(jī)已很普遍，PC-PLC、PC-STD、PC-NC等就是PC-DCS先驅(qū)，IPC成為DCS的硬件平臺(tái)。57C328DCS專業(yè)化：DCS為更適合各相應(yīng)領(lǐng)域的應(yīng)用，就要進(jìn)一步了解相應(yīng)專業(yè)的工藝和應(yīng)用要求，以逐步形成如核電DCS，變電站DCS、玻璃DCS、水泥DCS等。
發(fā)展方向
DCS發(fā)展至今已相當(dāng)成熟和實(shí)用，毫無(wú)疑問(wèn)，它仍是當(dāng)前工業(yè)自動(dòng)化系統(tǒng)應(yīng)用及選型的主流，不會(huì)隨著現(xiàn)場(chǎng)總線技術(shù)的出現(xiàn)而立即退出現(xiàn)場(chǎng)過(guò)程控制的舞臺(tái)。面對(duì)挑戰(zhàn)，DCS將沿著以下趨勢(shì)繼續(xù)向前發(fā)展：
(1)向綜合化方向發(fā)展：標(biāo)準(zhǔn)化數(shù)據(jù)通信鏈路和通信網(wǎng)絡(luò)的發(fā)展，將各種單(多)回路調(diào)節(jié)器、PLC、工業(yè)PC、NC等工控設(shè)備構(gòu)成大系統(tǒng)，以滿足工廠自動(dòng)化要求，并適應(yīng)開放式的大趨勢(shì)。
(2)57C328向智能化方向發(fā)展：數(shù)據(jù)庫(kù)系統(tǒng)、推理機(jī)能等的發(fā)展，尤其是知識(shí)庫(kù)系統(tǒng)(KBS)和專家系統(tǒng)(ES)的應(yīng)用，如自學(xué)習(xí)控制、遠(yuǎn)距離診斷、自尋優(yōu)等，人工智能會(huì)在DCS各級(jí)實(shí)現(xiàn)。與FF現(xiàn)場(chǎng)總線類似，以微處理器為基礎(chǔ)的智能設(shè)備如智能I/O、PID控制器、傳感器、變送器、執(zhí)行器、人機(jī)接口、PLC相繼出現(xiàn)。
Poor interoperability. Although analog instruments have unified 4-20mA signal standards, most technical parameters are still determined by manufacturers, resulting in the inability to exchange instruments of different brands. Therefore, it leads to users relying on manufacturers, unable to use the most cost-effective supporting instruments, and even a situation where individual manufacturers monopolize the market.
DCS industrial PCization: The composition of DCS by IPC has become a major trend, and PC has become a common operating station or node machine for DCS. PC-PLC, PC-STD, PC-NC, etc. are pioneers of PC-DCS, and IPC has become the hardware platform for DCS.
DCS specialization: In order for DCS to be more suitable for applications in various corresponding fields, it is necessary to further understand the process and application requirements of the corresponding profession, in order to gradually form DCS such as nuclear power DCS, substation DCS, glass DCS, cement DCS, etc.
Development towards comprehensiveness: The development of standardized data communication links and communication networks, combining various single (multi) loop regulators, PLCs, industrial PCs, NC and other industrial control equipment into a large system to meet the requirements of factory automation and adapt to the trend of openness.
Developing towards intelligence: The development of database systems, inference capabilities, and more, especially the application of knowledge base systems (KBS) and expert systems (ES), such as self-learning control, remote diagnosis, and self optimization, will be achieved through artificial intelligence at all levels of DCS. Similar to FF fieldbus, intelligent devices based on microprocessors such as intelligent I/O, PID controllers, sensors, transmitters, actuators, human-machine interfaces, and PLCs have emerged one after another.
