Description

Technical Field

[0001] The present invention relates to a dual-public and private LTE communication module for a fusion terminal in a distribution station area. The module provides two remote communication modes, namely, a public network (4G network) and a private network (1800MHz), for communication on the production side and the marketing side of the distribution station area. Background Art

[0002] The intelligent fusion terminal in the substation area is an important practice to realize the same source of data in the direction of distribution business. A smart fusion terminal in the substation area realizes the functions of the concentrator and the distribution transformer terminal at the same time. The same device carries out data collection and processing, which can realize the real-time sharing of data at the edge device level and effectively support business application needs. The intelligent fusion terminal in the substation area requires two long-distance wireless communications to access the distribution master station and the marketing master station respectively. In addition, in response to the problem of wireless public network communication security, some regions have built a power private network, which creates the need for public-private network switching. Therefore, in this context, the intelligent fusion terminal in the substation area requires two public-private integrated remote communication interfaces. The remote communication supports both wireless public network (4G network) and private network (1800MHz) communication modes. The two wireless communications send data to the distribution master station and the marketing master station respectively. Summary of the invention
