In view of this situation, after the analysis of the advantages and disadvantages of the existing system, based on the oil 1 loading stage whole lifting reconstruction project of CNOOC, this article has designed a set of hydraulic synchronous lifting control design scheme,in the use of modern measuring theory and technology, and on the basis of the synchronous lifting theory and control algorithm. In this article,firstly,it researchs the development level of building lifting and translation technology at home and abroad, and then designs a kind of control system which makes use of Electrohydraulic proportional pressure reducing valve + PLC + SCADA based on the actual engineering that,it introduces all sorts of control algorithm,and chooses the grey prediction fuzzy control algorithm as the system control algorithm to the request of control. Combined with the mathematical model of electrical and mechanical parts,it builds the model of control system through Simulink tool and simulated in Matlab, proves the feasibility of the control strategy theoretically, and highlights the advanced nature of the control strategy through parison with the traditional PID,mon fuzzy control it designs the hardware system and the monitoring system,the hardware system mainly includs hydraulic system,electrohydraulic proportional pressure reducing valve, PLC control cabis,sensor,and so on. Monitoring system uses as the development platform, in which develops the manmachine interface (HMI)。 PLC control software uses the special programming software GXDEVELOPER of Mitsubishi pile the ladder diagram control program。 designing the munication module between III PLC and WebAccess,and describing the munication mode and munication protocol. At last, according to the deficiencies and problems occurred in this project, we puts forward the direction that we need to improve and research in future.
