Real-time query method based on Internet of Things

Abstract

The invention discloses a real-time query method based on the Internet of Things (IoT). When a server is not used, a user terminal sends a query command via the corresponding IoT to a target IoT terminal, and the target IoT terminal collects data according to the query command and sends the collected data back to the user terminal via the IoT, thus the data instantaneity is improved and the cost is reduced. When the server is used, the user terminal sends the query command to the server, the server sends the received query command to a corresponding IoT gateway, the IoT gateway sends the received query command to the target IoT terminal, and the target IoT terminal collects data according to the query command and sends the collected data back to the user terminal along the path of the IoT gateway and the server. According to the method, a combination of long connection and short connection is also used, thus the system instantaneity is improved, and the IoT gateway and the electricity consumption of the user terminal are saved; and the success rate of data transmission is improved by automatically computing and dynamically updating the routing list.

Description

technical field [0001] The invention relates to a real-time query method based on the Internet of Things and belongs to the technical field of Internet of Things and Internet communication. Background technique [0002] At present, the existing Internet of Things real-time query sends the query command to the target client through the server, and this communication method is based on the support of the server connected to the Internet, and the target client device realizes instant communication through a specific software program installed inside. . The above-mentioned instant communication method is an existing Internet communication, and each client communication must be forwarded by the server, and a simple long connection or a simple short connection is often used between the client and the server. This single connection method often exists such as Disadvantages such as poor real-time communication, more clients, and relatively large server resource consumption. [000...

The above-mentioned instant communication method is an existing Internet communication, and each client communication must be forwarded through the server, and a simple long connection or a simple short connection is often used between the client and the server. This single connection method often exists such as Disadvantages such as poor real-time communication, more clients, and relatively large server resource consumption

[0003] In addition, in the communication between the Internet of Things terminal and the Internet of Things gateway, the method of preset fixed routing is generally used at present. This method of fixed routing has a low communication success rate when the communication network environment is unstable (such as the power carrier network). The problem
