Embodiment Construction
[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0020] Such as figure 1 As shown, a method for realizing instant messaging by the COAP protocol of the Internet of Things comprises the following steps:
[0021] (1) Data transmission: The IoT terminal device uploads the data packet. When the IoT terminal device uploads, the IoT terminal device reports the heartbeat data packet and the attribute information of the hardware device every minute. The attributes of the IoT terminal device use the JSON field ;
[0022] (2) Data sorting: The middleware communication layer receives the data packets uploaded by the terminal equipment of the Internet of Things, and sorts the data packets to obtain the sorting data. The sorting data includes the data packet sorting number and data packets, and the middlewa...
