12月14日——數(shù)據(jù)采集和監(jiān)控(SCADA)市場是全球增長最快的控制系統(tǒng)市場之一。由于對水電和污水基礎(chǔ)設(shè)施更新需求的增加，西歐和北美市場將在未來數(shù)年持續(xù)擴大。中東、非洲、亞太、拉丁美洲以及俄羅斯在油氣、電力、水和污水等領(lǐng)域的新投資也將刺激SCADA市場在這些地區(qū)的快速發(fā)展。制造商面臨的主要市場挑戰(zhàn)是確保加強網(wǎng)絡(luò)安全性。

　　Frost & Sullivan一份新的分析報告——“全球SCADA市場戰(zhàn)略分析”——表明該市場在2009年取得了45.845億美元的營收，預(yù)計到2016年這一數(shù)字將達到69.024億美元。該研究覆蓋了以下行業(yè)的終端用戶：油氣、電力、水和污水和其他覆蓋工廠級別SCADA的行業(yè)（食品，飲料，醫(yī)藥，化工，紙漿和紙），以及汽車和運輸。軟件、硬件以及服務(wù)是該研究涉及的一些產(chǎn)品類別。

　　Frost & Sullivan研究分析師Katarzyna Owczarczyk表示：“西伯利亞、北海、墨西哥灣、西北非的石油勘探獲得了新利益?？刂频乩砦恢蒙戏稚①Y產(chǎn)的需求使得資金雄厚的石油巨頭們投資于SCADA系統(tǒng)，從而支持市場的擴大?！?/p>

　　此外，天然氣由于其相對清潔的排放、相對低廉的價格以及豐富的存量而在全球能源市場越來越重要，因此替代石油和煤炭用于發(fā)電。將氣體傳輸?shù)浇K端用戶所用到的管道要求SCADA監(jiān)測泄露、流量、路線安排，從而進一步擴大市場規(guī)模。

　　Owczarczyk補充道：“實施之后，管道分配的設(shè)想將為提供SCADA系統(tǒng)的自動化企業(yè)創(chuàng)造大量的機會。對SCADA解決方案的需求將大幅增長，因為分配將涉及天然氣的長距離運輸。”

　　制造商在全球SCADA市場面臨的主要挑戰(zhàn)之一是確保加強網(wǎng)絡(luò)安全性。Owczarczyk指出：“大部分的SCADA供應(yīng)商已經(jīng)開始為基于TCP/IP的SCADA網(wǎng)絡(luò)開發(fā)專門的工業(yè)防火墻和VPN解決方案，解決網(wǎng)絡(luò)威脅的風險。另外，越來越多的應(yīng)用被實施于控制系統(tǒng)，旨在在不影響一般反病毒掃描性能的情況下，防止非授權(quán)的應(yīng)用改變?！?/p>

　　此外，ISA安全遵從研究所（ISCI）正在致力于規(guī)范SCADA安全性測試。由ISA99第4工作組定義的標準將取代原有的工業(yè)測試和認證標準，但在2011年之前這可能不會實現(xiàn)。

　　Owczarczyk總結(jié)道：“那些能意識到對網(wǎng)絡(luò)安全性、靈活開放系統(tǒng)有需求但同時滿足不斷增長的以有競爭力的價格獲得先進軟件的客戶期望的供應(yīng)商，將在未來的十年獲得生存。供應(yīng)商還應(yīng)該教育工廠工程師和操作人員，以及系統(tǒng)集成商和其他SCADA開發(fā)者關(guān)于安全性的重要性?！?/p>

December 15, 2010 - The Supervisory Control and Data Acquisition (SCADA) market is among the most rapidly growing control systems markets in the world. Markets in Western Europe and North America will continue expanding over the next few years due to the increasing demand to modernise power and water and wastewater infrastructure. New infrastructure investments in the Middle East, Africa, Asia Pacific, Latin America and Russia in sectors like oil and gas, power, water and wastewater, will also spur SCADA markets to grow rapidly in these regions. The key market challenge manufacturers have to face is ensuring enhanced cyber security.

New analysis from Frost & Sullivan, Strategic Analysis of the World SCADA Market, finds that the market earned revenues of $4,584.5 million in 2009 and estimates this to reach $6,902.4 million in 2016. The following end user sectors are covered in this research: oil and gas, power, water and wastewater and others covering plant level SCADA (food and beverage, pharmaceuticals, chemicals, pulp and paper) and automotive and transportation. Software, hardware and services are some of the product categories covered in this research.

“Oil exploration in Siberia, the North Sea, the Gulf of Mexico and North Western Africa has gained renewed interest,” notes Frost & Sullivan Research Analyst Katarzyna Owczarczyk. “The need to control geographically dispersed assets drives cash rich oil majors to invest in SCADA systems, thereby supporting market expansion.”

Moreover, natural gas is becoming increasingly important in the energy market globally due to its comparatively clean emissions, relatively low price, and abundant availability, therefore being an alternative to oil and coal for electricity generation. The gas pipelines needed to reach end users require SCADA monitoring for leaks, flow, and routing, further promoting market expansion.

“The concept of piped distribution, when implemented, will create numerous opportunities for automation companies in terms of supplying SCADA systems,” remarks Owczarczyk. “Demand for SCADA solutions will surge since distribution will involve the transportation of gas for long distances.”

One of the key challenges that manufacturers face in the world SCADA market is ensuring enhanced cyber security. "A great majority of SCADA vendors have started to address the risks of cyber threats by developing lines of specialised industrial firewall and VPN solutions for TCP/IP-based SCADA networks,” states Owczarczyk. “Additionally, more and more applications are being implemented to the control systems in order to prevent unauthorized application changes without impacting the performances of common antivirus scans.”

Furthermore, the ISA Security Compliance Institute (ISCI) is emerging to formalise SCADA security testing. Standards defined by ISA99 WG4 will supersede the previous industry testing and certification efforts, but probably not before 2011.

“Manufacturers that recognise challenges such as the need for cyber security, flexible and open systems while meeting rising customer expectations for advanced software at competitive prices will survive over the next decade” – concludes Owczarczyk. “Vendors should also educate plant engineers and operators, as well as system integrators and other SCADA developers about the importance of security.”
