Research On Distributed Control System For Rubber Sulfuration Procedure

With the development of computer technology, control technology, communication technology, CRT technology and so on, and with the industry production's need for improving the computer's control level, the management's centrality and decentralization prompt the development of Distributed Control System (DCS). DCS go through about 30 years from 70's to now, its technology is relatively mature. The future development will mainly be system miniaturization and micromation, the intelligent converter of the works, the standardization of field bus, the standardization of communication network, the mutual saturation of DCS and PLC, the introduction of artifical intelligence and specialist system for application and so on to the system software will be more consummated. DCS will adapt the need of all kind of process control much more ,will get economical effect more better.This project start off the practical need ,put forward a kind of small distributed control system. It use the existing industrial device and plant environment to carry through device reformation and system's foundation. It's main design goal is to attain the real response time and control time is not over 10 millisecond, and the control must be safety and reliability.On the platform of Win98, Using the Delphi programmable language , the software come true handy man-machine conversation. All present and historical production condition are stored in the corresponding table of paradox database. The software has convenient manipulation and Can print out and query the production station or working status.This project fill up the vacancy of the north of china in the rubber sulfuration control system, its attain the native advance level in the automation control area, and it pass the appraise Of province science and technology committee. After apply the project, the rubber sulfuration time is precisely controlled, quality can be greatly guaranteed, make the xing tai rubber limited corporation's economy benefit increase awfully, the production yield , annual sale ,annual profit increase by the rate of 10%. Social known and social status have also greatly boosted .This system have endured a year's circulation and inspection , the result approved that its stability ,safety and control in time all can fulfill the practical need .
