【正文】 o the scene as a control signal level control device. Therefore, the process control level to have a smart brain, able to soldiers to analyze the feedback of the military, and then make an order to make the soldiers can win war. his level is not the highest, equivalent to the army39。s lieutenant. It must be the same site feedback to a higher level of Colonel is the following about the process management level. Process management level DCS manmachine interface device, generally with a high resolution, large screen color CRT, the operator keyboard, printer, mass storage and so on. Select the operator station through the operation of various operating and monitoring production, This level is the operator with the DCS platform for exchange of information. DCS39。s core is shown operating with the management device. Operator through the operator station to monitor and control the production process, production can be learned through the operation of the screen to see the number of process variables with each state. This level be high in the armed forces, Colonel was. Its possession of power as needed to manually switch automatically at any time, modify the settings, adjust the control signals, control field devices to achieve the control of the production process. Management level Also known as the host puter, features, speed, large capacity. Through dedicated munication interface and highspeed data path connected, integrated surveillance system unit, and managing all system information. This is the highest whole plant floor automation systems. Only largescale distributed control system is qualified for this level. The military equivalent of the Marshal, they are for the user is a director, manager, chief engineer and other administrative or operational management personnel. It39。s a great privilege, you can monitor the operation of various departments, the use of historical data and realtime data to predict the various situations that may occur from the overall interests of business to help business executives make decisions to help panies achieve their program objectives. DCS system background 4039。s 3039。s last century, industrial automation equipment is used in dispersion control system. All equipment is run independently, not worked control. Operator calculated based on production requirements, will be independent of device characteristics to the appropriate level of regulation, and then began to work. After using a pneumatic, electric analog instrument into the process control system, a certain degree of centralized monitoring, operation and decentralized control. Better adapted to the needs of industrial production. However, with the production scale and plexity of the continuous improvement of the existing con
