In recent years, the technology of the Internet of Things has developed rapidly. How to integrate the data of the intelligent Internet of Things with the enterprise information system is the core technology of the Internet of Things. In this paper, we analyze the two existing schemes of SOA architecture, the integration of enterprise information system and the underlying sensor network, and propose a hybrid scheme to avoid the shortcomings of the existing schemes. According to the actual background of Gas Co.'s remote meter reading, an intelligent gas data management system based on CoAP is realized. The results show that the design scheme is feasible. This scheme has the characteristics of strong expansibility and high transmission efficiency.
