Research on UPIoT application of low-voltage station area based on dual-mode communication

The construction of ubiquitous power internet of things (UPIoT) puts forward higher requirements for the communication network in the station area. The single power line carrier (PLC), micro power wireless and other communication technologies have been difficult to meet the development needs. A dual-mode communication scheme that integrates the two technologies can achieve complementary gains and achieve reliable communication through adaptive channels. Firstly, studies the architecture of UPIoT communication system in station area, analyzes the requirements of the development of UPIoT business in station area for local and remote communication network, analyzes the current situation of two kinds of single-mode communication: local PLC and micro power wireless, analyzes the communication requirements of four types of UPIoT advanced non-metering application business. Focuses on the research of open network protocol architectures that are compatible with different devices, and a dual-mode channel and relay node adaptive selection mechanism satisfies the high-frequency data acquisition and real-time interaction is studied. On-site analysis show that this scheme can effectively improve the integrity and transmission rate of data acquisition, and realize the effective support for advanced non-metering application business in station area.
