Abstract: A predictive maintenance system and an implementation method thereof are provided. The system includes a mainboard, a sensing interface card coupled to the mainboard, and a predictive maintenance program. The mainboard includes a storage for storing a computer program and one or more processors for executing the computer program. The sensing interface card includes a sensor connection port that is configured to connect external device sensors with different connection interfaces and to receive detection values detected by the external device sensors, and a microprocessor for receiving the detection values to generate a failure prediction analysis result. The predictive maintenance program stored in the storage is executed by the processors.

Abstract: The present application provides a composition of corneal implantation, comprising: a collagen film, and renal proximal tubule cells which attached to the collagen film. In addition, the present application further provides a use of the composition of corneal implantation for implanting a patient with damaged cornea endothelium cells and a preparation method of the composition of corneal implantation.
