Distributed IOT (internet of things) system

Abstract

The invention relates to a distributed IOT (internet of things) system which comprises a sensor, an IOT gateway device and an IOT server. The IOT gateway device is connected with the sensor and the IOT server. The distributed IOT system is characterized in that the IOT server is connected with a data centre server. The system is easy to maintain, and only data in the data centre server needs to be maintained; the system is high in safety, and physical safety vulnerability caused by distributed data does not occur due to storage centralization; and the system is easy to expand, and storage hard disks of the data centre server can be increased dynamically, and data capacity expanding is an easy thing.

Description

technical field [0001] The present invention relates to an Internet of Things system, especially a distributed Internet of Things system. Background technique [0002] The Internet of Things gateway device is to embed and install sensors into various objects such as power grids, railways, bridges, tunnels, highways, buildings, water supply systems, dams, oil and gas pipelines, etc., and are generally connected to form the Internet of Things, from any The communication connection between people at any time and any place extends to the communication connection between people and things and between things and things. Its main function is to collect data from many types of on-site sensors, and transmit them to the background cloud server through various wireless and wired communication means for intelligent calculation, and to control various execution devices on site according to the results, so as to achieve Connectivity and smart functionality with things. With the advancem...

AI Technical Summary

Problems solved by technology

[0003] The previous IoT system adopted a standard C / S structure, and the IoT gateway device was directly connected to a single IoT server, and there was no dedicated data center server. Such a connection structure is simple and easy to implement, but there are also some shortcomings: 1. , the system is difficult to expand

And such a quantity is far from enough for higher orders of magnitude systems

2. The flexibility of networking is low

Due to security, cost and other requirements, most enterprises do not allow all their equipment to directly connect to the Internet, but instead use firewalls as the egress of the Internet, and impose strict restrictions on ports and numbers. Deploy a large number of IoT gateway devices internally

3. Low data storage flexibility

The previous system used a single IoT server structure, integrating storage and processing, resulting in difficulties in capacity expansion and hot backup

4. Low interoperability between endpoints

However, when the number of IoT servers increases, it is difficult to transmit information from one IoT server endpoint to another IoT server endpoint in a timely manner.
