Design and Implementation of Home Remote Monitoring System Based on Embedded Gateway

摘要

In order to improve the usability of the current home monitoring system, increase the storage capacity of historical data and solve the problem of strong system dependence, an embedded gateway design scheme is proposed. This scheme utilizes Qt's excellent cross-platform features to transplant Qt gateway program to Linux system based on ARM11 architecture. Socket programming is used for realtime data interaction, serial programming is used to parse the data received from the serial port, and the data is encapsulated in SQL format and sent to the cloud server. Mobile client is used for remote monitoring and historical query. While realizing the communication interface, the system architecture and communication protocol are elaborated. Data collection, upload and query are completed. The results show that the system is convenient for data query, expands data storage capacity and supports multiple operating systems, which can be successfully applied to home remote monitoring system.
