Abstract: Aiming at realizing the removal of hydraulic system testing equipments,modular design was implemented .The whole system was divided into two modules: the module of powersource and testing and the module of auxiliary oil source and control . The hydraulic testing system was divided into two sealed cabins through rational distribution and can be moved to the desired offshore drilling platform through lifting and transportation .The controlling system also take distribution as the control strategy .PLC and intelligent instruments were taken as the lower computer and IPCs(industrial personal computer ) and monitors constituent for the upper computer . The hardware configuration and software programming of PLC were accomplished through utilizing STEP7. The HMI was configured on the IPC by WinCC. Two control modes of totally automatic control and half automatic control were realized at last. The hydraulic components testing tasks can be realized efficiently through actually using.
