With the rapid development of big data and intelligence

data have played a decisive role in studies on air conditioning

and possession of good data management models appears to be extremely important. This article proposes

for the first time

a sharing scheme of electronic medical records for air-conditioning products using blockchain as the underlying technology

aiming to build a decentralized system that third-party trust can be omitted in an air-conditioning medical record information sharing platform. Through the use of hashing computing

asymmetric encryption

and a complete network consensus and other technologies

the air-conditioning fault record data of the entire network trustworthiness were achieved

breaking the trust barriers between individuals and enterprises. Research shows that the platform of electronic medical records for air-conditioning products based on blockchain technology can endow the data stored in it with the characteristics of immutability

relative transparency

and traceability to ensure complete credibility of the platform data. At the same time

its storage cost is relatively low

with an average storage cost of only 2 kB per case

which presents significant application prospects.
