Study and Application of steam long distance Measure and Control System

Aiming at the measure and control of the heat networks steam production and use, this paper studied steam long distance measure and control systems by computer, communication and flow measure theory etc. A set of distributive upper and lower steam long distance measure and control systems has been developed .The upper host is high function mini type computer. HW RWB high responsible Modem. The lower machine is intelligent flow meter with INTEL 8051 as its core, this system realized the remote real time monitor of heat network steam characteristics, set up a database of real time heat network steam characteristics. A predict model of heat network has been established by system identification according to the demands of users. With the help of this predict model, the production and control of boiler and steam turbine, accurate calculate product costing,save energy, effective production manage management can be scientifically supplied.
