140ARI03010140ARI03010140ARI03010DCS系统是继PLC之外的一大自动化控制系统，它在化工、火电等领域的应用极为广泛，但是生产方面的自动化技术需求进一步提高，传统的DCS系统已不能满足需要，需要进行技术升级。　　DCS系统由多台计算机分别控制生产过程中多个控制回路，同时又可集中获取数据、集中管理和集中控制的自动控制系统。分布式控制系统采用微处理机分别控制各个回路，而用中小型工业控制计算机或高性能的微处理机实施上一级的控制。　　经过这些年来的不断应用，DCS系统在行业发展的一些局限性逐步体现出来，DCS存在的问题：　　(1)1对1结构。1台仪表，1对传输线，单向传输1个信号。这种结构造成接线庞杂、工程周期长、安装费用高、维护困难。　　(2)可靠性差。模拟信号传输不仅精确度低，且易受干扰。为此采用各种措施提高抗干扰性和传输精确度，其结果是增加了成本。　　(3)失控状态。操作员在控制室既不了解现场模拟仪表的工作状况，也不能对其进行参数调整，更不能预测事故，导致操作员对其处于失控状态。因操作员不能及时发现现场仪表故障，而发生事故已屡见不鲜。　　(4)互操作性差。尽管模拟仪表已统一4～20mA信号标准，可大部分技术参数仍由制造商自定，致使不同品牌仪表无法互换。因此导致用户依赖制造厂，无法使用性能价格比最优的配套仪表，甚至出现个别制造商垄断市场的局面。　　发展方向　　DCS发展至今已相当成熟和实用，毫无疑问，它仍是当前工业自动化系统应用及选型的主流，不会随着现场总线技术的出现而立即退出现场过程控制的舞台。面对挑战，DCS将沿着以下趋势继续向前发展：　　(1)向综合方向发展：标准化数据通信链路和通信网络的发展，将各种单(多)回路调节器、PLC、工业PC、NC等工控设备构成大系统，以满足工厂自动化要求，并适应开放式的大趋势。　　(2)向智能化方向发展：数据库系统、推理机能等的发展，尤其是知识库系统(KBS)和专家系统(ES)的应用，如自学习控制、远距离诊断、自寻优等，人工智能会在DCS各级实现。与FF现场总线类似，以微处理器为基础的智能设备如智能I/O、PID控制器、传感器、变送器、执行器、人机接口、PLC相继出现。　　(3)DCS工业PC化：由IPC组成DCS已成为一大趋势，PC作为DCS的操作站或节点机已很普遍，PC-PLC、PC-STD、PC-NC等就是PC-DCS先驱，IPC成为DCS的硬件平台。　　(4)DCS专业化：DCS为更适合各相应领域的应用，就要进一步了解相应专业的工艺和应用要求，以逐步形成如核电DCS，变电站DCS、玻璃DCS、水泥DCS等。GE Fanuc IC600RM715K Data Storage IC600RM715-KCustom Dual Shaft Unwind Stand Adjustable Tension 90"Siemens HED43B015 HED HED4 15 Amp 15Amp 15A AGE Fanuc IC600RB750K I/O SwitchSiemens HED43B070 HED HED4 70 Amp 70Amp 70A A /w AlarmOriental Motor US590-502-K1 90W 200V Speed Control 1.1ASiemens HED43B100 HED HED4 100 Amp 100Amp 100A ACrompton CA-ECTU DC Amperes Meter 2500-0-2500A 237+01Square D I-Line Circuit Breaker FC34070 70Amp A 70 AmpAcopian B5G210 Regulated Power Supply AC Input 5V 2.1AWestinghouse Breaker NB NB31200F 1000 Amp A 1000AmpGE Fanuc IC600RB752K Device Switch IC600RB752-KSquare D SE40NCT Neutral Current Transformer 4000AGE Fanuc IC600RB751K CPU Switch IC600RB751-KKlockner-Moelle​r M9 Motor Drive for NZM9-250 BreakerWestinghouse DS-632 DS632 3200 Amp Amptector I - A LSIMitsubishi Breaker NF-SF3080 NF SF 80 Amp 80Amp 80A AEurotherm ECMA1/FA102 Control Master/Process MonitorMitsubishi Breaker NF-SF3070 NF SF 70 Amp 70Amp 70A AWestinghouse DS-632 DS632 3200 Amp Digitrip RMS510 LSIGSiemens ED63A003 ED ED6-ETI 3 Amp 3Amp 3A AYokogawa UT550-00 S3 Controller UT-500 ControlCrompton AA-LSTC AC Amperes Meter 0-1500A 237-02 AmpEurotherm ECMA1/FA108 Control Master/Extrusio​n ComboITE Gould 5600 5640 Fused Size 1 A203C MCC Bucket 30A Allen Bradley 1771-A3B1 12 Slot I/O Chassis IO 1771A3B1Square D Transformer 5kVA 240 x 480 120/240 V 5 kVA 3RBussmann KLP-2500 Hi-Cap Fuse 600V 2500A KLP2500 A AmpAllen Bradley Size Sz 1 15 A Amp 6in Breaker MCC BucketSquare D NCP361200 NCP 1200 Amp A 1200A 600vac 1200AmpSquare D NCP361200 NCP 1200 Amp A 1200A 600vac 1200AmpSew Eurodrive MQD32A/MM05C/Z3​8G0/AFI Movimot InverterFPE Transformer 20 kVA 460/230Y/133 V 230 Y 20kVA 3 PHWestinghouse A200M1CACM Size 1 Starter Style 277A534G01Yaskawa JANCD-XCP01C XRC CPU w/ XIF03 JANCDXCP01C GE Fanuc IC600BF946 Loop Management Module Rev L & KGeneral Electric GE CR7CA 10 Motor Starter 25A CR7CA10General Electric GE CL00D310T Motor Starter 25A CL00D*General Electric GE CL00A310T Motor Starter 25A CL00A*GE CR306E0**ABNA Size 3 Motor Starter General ElectricASCO 800 Amp Transfer Switch 208 Y / 120 V C940380049CGould ITE Telemecanique Sz Size 3 Motor Starter A203EModicon 170 BDI 542-50 115VAC Input AEG 170BDI54250 Mitsubishi A1SH42S1 Input Output Module 24VDC A1SH42-S1Mitsubishi A1SH42 Input Output Module 24VDC A1SH42 NEMIC LAMBDA JWS300-24 24V Power Supply JWS30024Crouzet GRD 84130103 Solid State Relay GRD84130103Cutler Hammer 9253C03H09 Neutral Sensor 1600:1 A 1ACutler Hammer CH AN16NN0 Size Sz 4 Starter 135A 240VLittelfuse KLP-C-1600 1600A Fuse 600V L A KLPC1600 NIBITE Gould 5600 Breaker Size 3 14HSt32A MCC Bucket 150A Mitsubishi A1SY41 Output Unit Module 12/24VDC A1SY41Mitsubishi/Freq​rol FR-A024-2.2KP AC Inverter 2.2K 230VCutler Hammer 3P82-601 Current Transformer 600:5 A 5ANEMIC LAMBDA EWS300-28 28V Power Supply EWS30028 Mitsubishi A1SY42 Output Unit Module 12/24VDC A1SY42Square D I-Line FY14020A FY-14020A FY 20 Amp 20A A NewWestinghouse Breaker MCP431800R 150Amp A 150AFanuc Ltd.
