Embodiment Construction

[0054] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0055] 1. IoT terminal node module design.

[0056] Such as figure 1 As shown, the IoT terminal of the present invention includes five main modules: a microprocessor module, a data transmission module, a data acquisition module, a storage module and a power management module.

[0057] The microprocessor module is required to carry an embedded operating system that supports multitasking, including the uIPv6 protocol stack, which can support IPv6 communication; at the same time, it connects the storage module and the power management module. The storage module is required to contain a certain byte of on-chip memory, and the external interface can be configured with a certain capacity of flash memory; the power management module is required to have the characteristics of low power consumption, prolong the working time of the node, and require no exte...

Abstract

The invention discloses a method for communicating a terminal of the internet of things with a host of the internet on the basis of IPv6 (internet protocol version 6). The method includes adding 6lowpan protocol into a protocol stack of the terminal of the internet of things to match data packets, namely supporting the network layer by the 6lowpan protocol and the IPv6 protocol; and utilizing 802.15.4 of IEEE (institute of electrical and electronic engineers) to perform data communication with a gateway on a link layer, realizing lightweight data packet transmission of the link layer in the lowpan area via the 802.15.4 protocol, utilizing the UDP (user datagram protocol) and the ICMP (internet control messages protocol) on a transmission layer of the terminal of the internet of things, and subjecting the gateway and the host of the internet to data communication via the Ethernet. A context active updating mechanism is realized in the terminal of the internet of things and is used for the process that the IPv6 host in the internet actively access to the terminal of the internet of things in the lowpan area, and meanwhile, the process of the terminal of the internet of things that data are actively reported to the host of the internet is provided, and the problem about mutual communication and connection between the terminal of the internet of things and the host of the internet is solved.

Description

technical field [0001] The invention relates to an IPv6-based communication method between a lightweight terminal of the Internet of Things and an Internet host, and belongs to the technical field of terminal applications of the Internet of Things. Background technique [0002] With the development of the Internet of Things industry, the number of Internet of Things applications is increasing, and the coverage is becoming wider and wider. The Internet of Things terminals have the characteristics of large number, wide coverage, high density, battery power supply, and limited energy resources. Aiming at these characteristics, the design and research of node circuit integration, low power consumption energy management, node integration, and lightweight network protocol stack are carried out for applications. At present, the research on IoT terminals is basically based on applications, and different terminals are developed for different applications, which makes IoT application...
