An intelligent public toilet equipment interaction method and system based on an MQTT protocol

Abstract

The invention discloses an intelligent public toilet equipment interaction method based on an MQTT protocol, and the method comprises the steps: collecting data detected by public toilet equipment through an information collection card, publishing the detected data to an MQTT server through a specific theme, and uploading the detected data to a data statistics server. And after the message filterreceives the message, filtering the message according to a user-defined matching algorithm, and issuing the filtered message to the MQTT agent. And after the mobile terminal subscribes the required theme, judging whether to remotely debug the public toilet equipment according to the received message, and sending the debugging information to the public toilet equipment through the MQTT server again. According to the data interaction method, message filtering is carried out on the data generated by the public toilet equipment, pushing of useless messages is greatly reduced, and the communicationprocess is more flexible and efficient.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an MQTT protocol-based intelligent public toilet equipment interaction method and system. Background technique [0002] The Internet of Things refers to information sensing devices such as RFID, infrared sensors, GPS, and laser scanners. According to agreed agreements, any item is connected to the Internet for information exchange and communication to achieve intelligent identification, positioning, and tracking. , monitoring and management of a network. With the continuous development of technologies such as the Internet and the Internet of Things, the application of Internet of Things technology is becoming more and more extensive. [0003] In the existing Internet of Things applications, the number of terminal devices is often very large, the communication relationship is mostly in a mesh topology, and most of the collected data has the characteristics of small volume an...

Problems solved by technology

In the basic structure of MQTT, the subscriber only subscribes to the topics he is interested in without understanding the internal structure of the message. The subscriber cannot express interest in part of the message in a more fine-grained manner, and his expressive ability is weak, while the message broker will All messages under this topic are pushed to subscribers, which will cause a lot of useless messages to be pushed, resulting in network congestion, increasing server load and communication bandwidth
