Abstract

The invention discloses an internet-of-things gateway achieving IP virtualization conversion. The internet-of-things gateway comprises two real network adapters which are simultaneously connected with a network adapter scheduling module, one real network adapter is a main real network adapter, and the other real network adapter is a standby real network adapter; the network adapter scheduling module is connected with a data storage module and at least two virtual network adapters, each virtual network adapter is correspondingly connected with a data communication module, at least one data communication module is connected with a signal input module, and the other data communication module is connected with a signal output module; the signal input module is connected with a sensor, and the signal output module is connected with an agriculture control device; an input channel is formed between the signal input module and the corresponding virtual network adapter, and an output channel is formed between the signal output module and the corresponding virtual network adapter.

Description

technical field [0001] The invention relates to the field of agricultural Internet of Things and agricultural automation, in particular to an Internet of Things gateway for IP virtualization conversion. Background technique [0002] In traditional technology, most of agricultural production still uses manual labor. Even mechanized large-scale production is only in the terminal links of transplanting, watering and harvesting of crops, lacking an automated solution for integrated management. [0003] The rapid development of the Internet of Things technology has further appeared in the agricultural field, but the existing agricultural Internet of Things technology is only a way of one-to-one control and individual connection. The layout structure of the entire agricultural automation Internet of Things is relatively backward, and the control network imperfect. Contents of the invention [0004] Purpose of the invention: The technical problem to be solved by the present inv...
