Fault diagnosis method for core unit of flexible printing electronic equipment

The invention discloses a fault diagnosis method for a core unit of flexible printing electronic equipment, and aims to realize an interactive system which can acquire vibration signals of core parts of the flexible printing electronic equipment in real time, and then quickly diagnose and feed back the vibration signals. The system has the advantages of being high in response speed, large in data storage amount, low in cost, high in safety and reliability, high in data traceability and confidentiality and the like. The method comprises the following steps: continuously collecting vibration signals in a running state of a core component of the flexible printing electronic equipment, packaging and chaining the vibration signals, continuously diagnosing the vibration signals, sharing a fault diagnosis algorithm, dynamically storing data, responding in real time and quickly diagnosing. According to the method, the blockchain can be utilized to realize dynamic storage of the data, improve the calling efficiency of
