Real-time alarm method based on Internet of things

Abstract

The invention discloses a real-time alarm method based on the Internet of Things. When the server is not used, the preset alarm event is detected in real time through the automatic inspection module of the IoT terminal; if a preset alarm event is detected, the IoT terminal sends the alarm event information to the IoT gateway; the IoT gateway Send alarm event information to authorized user terminals. When using the server, the preset alarm event is detected in real time through the automatic inspection module of the IoT terminal; if a preset alarm event is detected, the IoT terminal sends the alarm event information to the IoT gateway; the IoT gateway sends an alarm The event information is sent to the server; the server sends the alarm event information to the authorized user terminal. The present invention further uses the combination of long and short connections to improve the real-time performance of the system and save the power consumption of IoT gateways and user terminals. In addition, by automatically calculating and dynamically updating the routing table, the success rate of data transmission is improved.

Description

technical field [0001] The invention relates to a real-time alarm 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 alarm push server pushes the alarm information to the user terminal, and this communication method is based on the support of the server connected to the Internet, and the client device realizes instant communication through a specific software program installed inside. According to the existing Internet instant communication method, each client communication must be forwarded by the server, and the client and the server often simply use long connections or simply use short connections. This single connection method has some disadvantages , such as poor real-time communication, many clients, and high server resource consumption. [0003] In addition, in the communication between the Internet of Things terminal and ...

According to the existing Internet instant communication method, each client communication must be forwarded by the server, and the client and the server often simply use long connections or simply use short connections. This single connection method has some disadvantages , such as poor real-time communication, many clients, and high 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
