Power distribution Internet of Things network communication system based on CoAP protocol

Abstract

According to the power distribution Internet of Things network communication system based on the CoAP protocol, communication is carried out by using the same protocol in different network environments, so that the complexity of system communication is greatly reduced, and the problem that equipment is difficult to cooperate due to large difference of communication protocols of power distribution network equipment is avoided. According to the invention, a rapid communication line can be dynamically selected without according to a network environment where the power distribution Internet of Things terminal is located, efficient communication between a mobile application side and a power distribution Internet of Things intelligent terminal side is maintained, and rapid response of services is realized. The service type and the belonging application scene are determined according to the data packet interacted in the power distribution Internet of Things, the protocol mode is dynamically selected, and the service quality is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a CoAP protocol-based power distribution Internet of Things network communication system. Background technique [0002] Power distribution IoT terminals are often located in various heterogeneous network environments. In order to meet the needs of different application scenarios of power distribution IoT, the terminal should have the ability to perceive scene changes, and based on this, optimize the decision to select the best Network channels to maintain efficient and smooth communication. [0003] In the current actual power distribution business, protocols such as CoAP and MQTT are usually used on the Internet side for communication between mobile applications and distribution IoT terminals, while TCP and UDP protocols are used for communication on the LAN side. The protocols used are different, and the communication implementation methods are different, result...
