Embodiment 1

[0021] This embodiment provides a data publishing system. Before describing the system, firstly, a brief description will be given of the implementation scenario of the system.

[0022] There are multiple electronic devices in a certain area, and each electronic device is equipped with a corresponding data collector; a controller is arranged in the area, and the controller can be a DDC (Direct Digital Control, direct digital controller). DDC is used as an example to illustrate how many data collectors it can connect to according to the number of points that can be connected to the DDC, so there may be multiple DDCs in one area; there is only one data router in each area, and the data router is connected to multiple DDCs; the data management layer The distributed construction of the data scheduling layer is not limited to a certain area. The data manager and data distributor can be deployed in the same area or in different areas; the user terminal equipment is not limited to the...

Embodiment 2

[0045] This embodiment provides a data publishing method, which can be executed by the data publishing system provided in Embodiment 1 above, Figure 4 is the flowchart of the method, such as Figure 4 As shown, the device includes the following processing:

[0046] Step 401: Receive a request to establish a connection with the controller sent by the client device;

[0047] Step 402: Create a publisher and a subscriber according to the channel identifier corresponding to the controller indicated in the connection request;

[0048] Optionally, in this embodiment, the operation of creating a publisher and a subscriber according to the channel identifier corresponding to the controller indicated in the connection request may include: selecting data based on the principle of the shortest path and / or the largest transmission rate according to the network delay situation Distributors create subscribers and create publishers.

[0049] In this embodiment, the publisher and the subs...

Abstract

The invention discloses a data publishing system and method to at least solve the problem of poor real-time data collection of the Internet of Things in the related art. The public data release system includes: a data collector, used to collect data from devices connected to it; a controller, used to receive device data collected by the data collector, and send the received device data to the data manager; the data manager , used to receive the device data sent by the controller, and send the received device data to the data distributor; the data distributor is used to receive the request sent by the client device to establish a connection with the controller, according to the channel identifier corresponding to the controller A publisher and a subscriber are created, wherein the subscriber is used to monitor the control instruction sent by the client device, and the publisher is used to send the device data indicated by the control instruction to the client device. The disclosure improves the real-time performance of the data collected by the Internet of Things.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a data release system and method. Background technique [0002] With the rapid development of the Internet of Things, how to collect data from physical devices in real time and respond quickly to users is the first and important step of the Energy Internet. At present, in related technologies, the purpose of data collection and transmission of the Internet of Things can be realized through centralized management. However, in the Internet of Things across regions or even on a larger scale, collecting data and transferring the data to the database in the way of subscription / publishing centralized management will result in poor real-time performance of the data, which is not suitable for the current global Internet of Things rapid response needs. Contents of the invention [0003] The present invention provides a data publishing system and method to at lea...
