Abstract
With the continuous development of the scale of power Internet of things, the accumulation and increase of acquisition equipment and data, the traditional secure access gateway can not well meet the complexity requirements of relevant business systems in the transmission industry. This paper studies the common access technologies and business scenarios of Internet of things gateway. Combined with the design concept of micro service architecture, this paper puts forward a design scheme of unified access security gateway in transmission industry, which meets the needs of multi type equipment access and massive third-party data exchange of transmission platform, and realizes authentication, authorization, flow control, access control, routing conversion, protocol conversion, log monitoring and other functions. At present, the security gateway based on this design scheme has passed the system security detection of Electric Power Research Institute, and has been applied in the panoramic monitoring platform of transmission line in Qinghai Province, and achieved good results.
