Cloud interconnection system for electric quantity collection based on MQTT protocol

Abstract

The invention discloses a cloud interconnection system for electric quantity collection based on an MQTT protocol. The cloud interconnection system comprises a bottom hardware layer, an equipment driving layer, an operating system layer and an application software layer. The bottom hardware layer initializes an ARM system by configuring an ARM related register; the equipment driving layer performsmacro definition on related registers in the bottom hardware layer, and calls macros in tasks and ISRs to obtain related data; the operating system layer provides system support for the application software layer; the application software layer is subdivided in an interrupt and task mode, and corresponding functions are executed in the interrupt and task mode in a function calling mode. A modulardesign concept is used in the design of hardware and software, so that the development cost can be reduced, and the maintenance difficulty is reduced.

Description

technical field [0001] The invention relates to a cloud interconnection system for power collection based on the MQTT protocol. Background technique [0002] The intelligent electricity collector is obtained through innovation on the basis of the electric energy meter. The earliest watt-hour meter was a direct-current watt-hour meter developed by Edison in 1880 using the principle of electrolysis. The meter weighed tens of kilograms and had no accuracy guarantee. A single-flux inductive AC watt-hour meter with an independent current core, this meter weighs 36.5 kg, of which the voltage core weighs 6 kg. In 1890, a multi-flux induction watt-hour meter with a current core was born, but its rotating element was a copper ring, and the reaction torque was generated by an AC electromagnet. [0003] In the 1930s, nickel steel and aluminum-nickel alloy magnets appeared, and the volume of the electric energy meter was further reduced. The improvement of the performance of the magne...

Problems solved by technology

In recent years, with the rise and promotion of smart grids in various countries around the world, as the terminal of smart grids, power collectors have been promoted and applied in many countries. So far, Italy is the pioneer in this area, and many countries have developed corresponding Types of power collectors, but because there is no unified definition of power collectors in the world at present, countries have formulated their own standards or technical documents for power collectors according to their actual conditions, which limits the intelligent power collectors to a certain extent. Further promotion and development of the acquisition instrument in the world

[0005] As far as intelligent power collector products are concerned, at present, many domestic electrical equipment companies have also launched their own products in the field of intelligent power collectors, but the products are generally limited to a certain application field, and due to insufficient R&D investment, there is still no It cannot provide an overall solution, and there is a big gap in the product in communication, monitoring system, standard adoption, etc., and it does not support the MQTT protocol, so it is difficult to be widely promoted in the Internet of Things
