Electronic fault record sharing platform for building air-conditioning based on blockchain technology

In today’s rapid development of air-conditioning intelligence, blockchain technology has become the key to breaking through the trust barrier to air-conditioning data. Data plays an important role in air-conditioning intelligence. However, the distrust of data has not only hindered the circulation of data, but also limited the further development of air-conditioning intelligence. In order to break through the trust barrier to air-conditioning data, this paper proposes an electronic fault record sharing platform for building air-conditioning based on blockchain technology. The platform utilizes key technologies such as hash algorithm, consensus algorithm, and asymmetric encryption in the blockchain, and chooses the Ethereum network as its deployment platform. The core feature of this platform is its use of blockchain technology to ensure that the data uploaded to the platform is tamper-proof, transparent, and traceable, which achieves completely trustworthy storage within the blockchain and breaks down the trust barrier between individuals and individuals, and between enterprises and enterprises. The results of the study show that smart contracts of the Ethereum platform are excellent in handling electronic fault records, which also provides an entry point for the integration of blockchain with building air-conditioning. In addition, the building air-conditioning electronic fault record sharing platform based on blockchain technology also has a low data storage cost, showing broad prospects for its practical application. Through the application of blockchain technology, the trustworthiness of air-conditioning data is improved, providing a solid foundation for the further development of air-conditioning intelligence.
