Self-sovereign identity (SSI) has gained a large amount of interest. It enables physical entities to retain ownership and control of their digital identities, forming a conceptually decentralized architecture. With the support of distributed ledger technology (DLT), it is possible to implement this conceptually decentralized architecture in practice and further bring technical advantages such as privacy protection, security enhancement, and high availability. However, developing such a relatively new identity model has high costs and risks with uncertainty. To facilitate the use of the DLT-based SSI in practice, we formulate Self-Sovereign Identity as a Service (SSIaaS), a concept that enables a system, especially a system cluster, to readily adopt SSI as its identity model for identification, authentication, and authorization. We propose a practical architecture by elaborating the service concept, SSI, and DLT to implement SSIaaS platforms and SSI services. Besides, we present an architecture for constructing and customizing SSI services with a set of architectural patterns and provide corresponding evaluations. Furthermore, we demonstrate the feasibility of our proposed architecture in practice with Selfid, an SSIaaS platform based on our proposed architecture.

The traditional power equipment material quality control business relies on the work experience of field operators, it fails to form standardized digital information records, and has poor traceability. In order to improve the above problems, this paper designed a digital power material quality control information system based on augmented reality technology, and developed an augmented reality wearable intelligent terminal device based on 5G communication and artificial intelligence technology. This has formed an innovative operation mode of audio and video recording of important work information at business key points and remote interactive support of experts;The professional orientation functions such as spatial ranging, vernier caliper reading recognition and partial discharge characteristic spectrum recognition are realized. Relying on the developed system and device, the digital upgrade, cost reduction and efficiency increase of power equipment manufacturing supervision, inspection and detection business are realized.

The wireless power transfer system of double-sided LCC topology has the characteristics of high-order and nonlinear, which increases the difficulty of controller design. In this paper, a voltage stabilizing closed-loop control system based on the model of generalized state space average (GSSA) and order reduction is proposed. The GSSA model of the system is established, and the small signal model is established according to the nonlinear characteristics of the system;Then, through the balanced order reduction method, the 17th order system is reduced to the 3rd order system;Furthermore a PI controller is designed to ensure the stability of the 6.6kw electric vehicle wireless charging system, output voltage;Finally, by the simulation results of the closed-loop control system, that the transient response time of output voltage is 15ms and the response time of load switching is 14ms, and the effectiveness of the proposed mothed is verified.
