In order to solving the defects of carrier rocket accumulator charge and discharge equipment, such as shortage of automatic equipment, high risk of handwork, no effective fault diagnosis and disposal, apply virtual equipment technique into rocket accumulator charge and discharge equipment, and design new rocket accumulator charge and discharge equipment, which is made up of hardware and software. The hardware adopts PXI observe and control platform, and software is made up of charge, discharge and warm up equipment. By manufactory test, launch site test and software test, it indicates that the method can improve automatic degree and intelligent degree of the equipment.
