Design of a Miniature Communication Conversion Module Applied in the Power Internet of Things

In order to solve the security access problem of power Internet of Things customer side, this paper has designed a miniature communication conversion module which can be deployed in the perceptual layer or marginal layer in power Internet of Things client side. This device can realize such functions as security isolation, information security interaction, access authentication, data/instruction encryption protection, etc. In order to verify the performance of the miniature communication conversion module, this paper has also constructed the testing system for miniature communication conversion module, and tested its security performance. The test results showed that the device can securely isolate the open customer access network from the core network of the power Internet of Things, effectively preventing the core business system from being illegally invaded.
