Compared with the prior art, the invention has the advantage that with the advancement of the technology, many devices currently used by humans are complex systems which cannot be completely mastered and recognized by humans, and many defects in such systems cannot be predicted and eliminated by humans. In order to ensure the safe operation of the equipment, equipment health management concepts have been proposed. The traditional equipment health management is also based on a method for collecting data through manual inspection, so the equipment management effect depends on the experience and the capability of workers collecting the data, and also depends on the inspection frequency of the workers, if the experience and the capability of the workers collecting the data are rich, the data effectiveness is higher, and if the inspection frequency is high, the probability of determining the problem in the early stage is higher. However, historical experience has shown that, in many cases, due to efficiency and profit pursuits of enterprises, the polling frequency is not too high, the worker ability is not too strong, and in order to avoid the problem caused by the factors, an equipment health management method without human intervention is required. Aiming at the problems in the prior art, the application provides a method and a system for transmitting equipment health management big data based on a block chain.
