Internet-of-things terminal platform data encapsulation method

Abstract

The invention relates to the technical field of network protocol encapsulation, and specifically relates to an Internet-of-things terminal platform data encapsulation method. The method is characterized by comprising the steps of defining a data encapsulation protocol on an application layer of an Internet-of-things terminal and a service platform, in order to provide a universal data encapsulation interface for communication between the Internet-of-things terminal and the service platform; after a data receiving module receives data acquired by a corresponding sensor, sending the data from the Internet-of-things terminal to the service platform, coding and encapsulating the acquired data according to the format of the data encapsulation protocol to form a data packet, then transmitting the data packet to the service platform, receiving, by the service platform, the corresponding data packet, and decoding the data packet. Compared with the prior art, the method has the advantages that a universal data encapsulation interface is provided for communication between the Internet-of-things terminal equipment and the service platform, and the method can be used for unified encapsulation of data acquired by different sensor equipment in different industries, so that the data processing requirement of the service platform can be reduced.

The WMMP protocol is designed to realize the data communication process between industry terminals and M2M platforms. Since the GPRS network bandwidth is narrow and the delay is large, it is not suitable for communication using the TCP protocol. Therefore, this protocol is based on the UDP protocol. UDP The protocol is transmitted in a connectionless manner, which has the advantages of high efficiency, small traffic, and saves network bandwidth resources. The disadvantage is that there is no confirmation mechanism, which may cause packet loss. Generally, it is necessary to implement packet confirmation and packet similar to TCP through the upper application layer protocol of UDP. Retransmission mechanism to improve communication efficiency and reliability, resulting in highly coupled data transmission control and data encapsulation of the WMMP protocol, which cannot effectively utilize existing IoT data transmission protocols
