With the development of information technology, computer and network have been widely applied into the area of energy consumption, energy conservation and pollution reduction. Information technology brings convenience into energy conservation and environment protection management, but at the same time, it also brings security issues. In the area of energy consumption, a lot of sensitive data related to national economy and society are on-line collected. Once data theft, it will bring immeasurable losses. Furthermore, data transmission between the existing energy consumption monitoring equipment and platform has no unified interface or standard. So this paper designed a chip, used as core chip in gateway, for compatibility, standards and safety during transmission, which will provide hardware and technical support for the government and enterprises to carry out monitoring of energy consumption and conservation, to achieve energy conservation and emissions reduction targets.
