Fuente: Wipo "Sensorization" An industrial machine predictive maintenance system may collect data indicative of operating characteristics of an industrial machine. The system can include a computerized maintenance management system (CMMS) that produces orders and/or requests for service and parts responsive to industrial machine service recommendations, including a mobile data collector that indicates the industrial machine service recommendation or the produced orders or requests for service and parts to a worker who uses the mobile data collector. A self-organizing data collector can cause a new record to be stored in a ledger, the new record indicating at least one of the industrial machine service recommendation or the produced orders or requests for service and parts. The ledger can use a blockchain structure to track records of transactions for each of the orders and requests for service and parts, wherein each record is stored as a block in the blockchain structure.
