Energy Internet of Things data acquisition method based on non-blocking input and output model and software gateway

Abstract

The invention provides an energy Internet of Things data acquisition method and a software gateway using a non-blocking input / output model NIO (Non-blocking Input / Output). Pure software such as load balancing and the like and a cloud computing technology are used for solving the problems in the field of energy internet of things under various sensing equipment and communication equipment access scenes; a traditional pure hardware gateway is high in multi-communication protocol compatibility difficulty, difficult to support high-availability requirements of a system in a high-concurrency scene,poor in dynamic expansion capacity and the like. The implementation process of the method comprises the steps that a collector is connected with a communication gateway, a scheduling task is used fordata collection, data processing and data forwarding.

Description

Technical field [0001] The present invention relates to the field of energy Internet of Things, and specifically provides a method of using non-blocking input / output model NIO (Non-blocking Input / Output) and load balancing technology to solve how energy Internet of Things achieves high concurrency and high concurrency under the scenario of TCP network long connection. Available questions. Background technique [0002] With the development and advancement of the Internet of Things technology, a large number of energy Internet of Things equipment terminals such as electrical meters, water meters, gas meters, electrical fire detectors, combustible gas detectors, temperature sensors, etc. are used for energy online monitoring index collection and monitoring applications , And upload a large amount of data in real time, which brings huge challenges to IoT gateway data collection and real-time processing. How to improve the concurrent processing capacity of the gateway in a short time ...

Problems solved by technology

And because the uploaded data format of various monitoring terminals collected by sensors in real time is not uniform

For example, although different meter manufacturers follow the industrial communication Modbus protocol development, but due to the different register addresses and index calculation offsets, the protocols uploaded to the collection platform are different.

However, the current energy Internet of Things communication gateway architecture cannot solve the problem of accessing a large number of heterogeneous terminal devices, and cannot automatically switch over the failure of the collection server, and the writing of a large amount of data leads to a single point of failure in the gateway service and is prone to performance issues. bottleneck problem
