Internet-of-thing communication system and method based on middleware and MQTT protocol

The invention belongs to the technical field of Internet of Things communication, and particularly relates to an internet-of-thing communication system and method based on middleware and an MQTT protocol. The internet-of-thing communication system comprises a communication equipment layer and a transmission layer. The communication equipment layer comprises HTTP protocol equipment, COAP protocol equipment, MQTT binary transmission equipment, TCP protocol equipment and UDP protocol equipment; the transmission layer sequentially comprises a data access layer, MQTT own protocol middleware and AMQP protocol internal data communication middleware from bottom to top; and the AMQP protocol internal data communication middleware is configured to be in communication connection with an upper layer service system. According to the invention, (1) through establishing various protocol communication equipment access middleware and data analysis middleware of the transmission layer, the internet-of-thing communication syste
