区块链正在经历快速发展，并具有彻底改变工业领域物联网平台的全部潜力。本文提出了一种轻量级的基于区块链的IIoT平台，以解决IIoT生态系统构建过程中的安全，信任和孤岛连接问题。BPIIoT由链上网络和链下网络组成。所有交易都在链上网络中处理，例如包括基于访问控制和可编程权限的数字签名。链下网络处理区块链无法解决的存储、复杂的数据处理和其他问题。智能合约作为消费者和制造资源的服务合约，提供按需制造服务。通过制造设备数据共享和智能制造的维护服务共享两个智能应用案例，阐述了BPIIoT在维护、维修、运营服务网络中的设备维护服务和状态数据共享服务的智能合约。
Blockchain is experiencing rapid development and has the full potential of revolutionizing the IoT platform in the industrial field. In this paper, a light-weighted Blockchain-based platform for IIoT is presented to address security, trust, and island connection problem in the process of IIoT ecosystem construction. BPIIoT is comprised of the on-chain network and the off-chain network. All transactions are processed in the on-chain network such as including digital signature based on access control and programmable permission. The off-chain network deals with the storage, complex data processing, and other problems that blockchain cannot solve. The smart contract is utilized as the service contract of consumers and manufacture resources, providing on-demand manufacturing service. Two smart application cases, manufacturing equipment data sharing and maintenance service sharing from smart manufacturing, are implemented to explain the smart contract for equipment maintenance service and status data sharing service throughout maintenance, repair, and operation service network by the BPIIoT.
