Multi-source polymorphic massive heterogeneous terminal pan-access interconnection protocol conversion method and system

Abstract

The invention discloses a multi-source polymorphic massive heterogeneous terminal pan-access interconnection protocol conversion method and system. The method comprises the following steps: determining the position of an MQTT protocol in a power distribution Internet of Things communication protocol in an ISO seven-layer system and a protocol stack data structure; message interaction is completed by adopting a publishing or subscribing mechanism through an MQTT protocol so as to provide one-to-many message distribution; defining an MQTT data packet structure, wherein the MQTT data packet structure comprises a fixed message header, a variable message header, an information body, a theme and a message body; defining an SDK (Software Development Kit), carrying out secondary development on the equipment through the SDK, accessing the manufacturer equipment to an Internet of Things platform, and carrying out unified management by the Internet of Things platform; multi-instance cascade deployment is realized through the Internet of Things platform, so that plug and play of various service terminals accessed to the Internet of Things platform is realized. According to the invention, an agile development SDK tool can be used for large-scale deployment in a multi-source and multi-state power grid scene, and plug and play of various service terminals accessed to an Internet of Things platform is realized.

Description

technical field [0001] The present invention relates to the field of computer application technology, and in particular to a method, system, terminal and computer-readable storage medium for converting a multi-source, multi-state, massive heterogeneous terminal, pan-access interconnection protocol. Background technique [0002] In modern grid operation, with the development of wireless communication, hardware equipment and intelligent manufacturing technology, the grid operation process has become more automated, complex, and precise than before, making grid monitoring more difficult. Therefore, the State Grid is proposing the strategic goal of building a world-class "Energy Internet", among which building a "Strong Smart Grid" and "Ubiquitous Power Internet of Things" is an important support for realizing this goal. [0003] Comprehensively promoting the application of the smart IoT system, promoting the practicality of the IoT platform, realizing cross-professional co-cons...
