Abstract

The present invention relates to the technical field of multi-terminal low-power wireless transmission, and is a single-type multi-terminal low-power wireless transmission system and a transmission method thereof. The former includes a centralized control unit and several terminal node units, and the centralized control unit includes a first wireless A communication module and a core control module, the core control module includes a mode judgment and switching module, a second wireless communication module, a mode judgment and switching module are arranged in each terminal node unit, and are used to switch the application scenario of the centralized control unit according to the command . The present invention realizes the low-power switching strategy selection of multiple application scenarios in a single-type multi-terminal wireless transmission system, further optimizes the speed of the data transmission process, and reduces the power consumption of wireless transmission in a single-type multi-terminal wireless transmission system. Among the two modes of a multi-terminal node command and multiple single-terminal node commands, the command transmission is performed in a mode with low energy consumption, which effectively reduces the overall power consumption of the system.

Description

technical field [0001] The invention relates to the technical field of multi-terminal low-power wireless transmission, and relates to a single-type multi-terminal low-power wireless transmission system and a transmission method thereof. Background technique [0002] With the rapid development of information today, the Internet of Things technology connects huge terminal equipment, which further improves the full automation of terminal equipment. Based on the big data analysis technology of the Internet of Things industrial data system, artificial intelligence technology has improved the ability of systematic and intelligent decision-making. In the application environment of information collection and terminal control, a huge wireless communication network system is formed by deploying a large number of measurement and control nodes. The positions of the nodes are generally scattered and not easy or even unrecoverable. Therefore, the service life of the nodes directly affects...
