基于树莓派与MQTT的智能网关设计
Intelligent Gateway Design Based on Raspberry PI and MQTT
摘要
Abstract
Aiming at the problems of the diversity of terminal node data transmission protocols and the centralization of network services in the Internet of Things environment,a co-processing gateway based on MQTT protocol is designed.The gateway selects Raspberry PI as the hardware platform,takes embedded mobile devices as the basis,and builds a system structure integrating service agent,data management,protocol conversion,status monitoring and other functions based on the message transmission model of MQTT protocol event publishing and subscription.A communication link consisting of perception layer,service layer and application layer is also established.The whole configuration of gateway system and the design of message publishing and subscription model are completed,and the two-way communication between gateway,sensing device and user is realized.The experimental test shows that the intelligent gateway can establish a stable communication connection,accurately complete the data receiving and sending,and realize the data communication between multiple points.The data transmission process is stable,and no information loss occurs in the test process.The intelligent gateway of MQTT protocol structure realizes the decoupling of the two sides of the message in time,space and synchronization.The gateway alleviates the congestion caused by centralized network services,improves the general processing capacity of data,and improves the efficiency of data transmission.关键词
