Node address coding method of wireless communication system, wireless communication system and equipment

Abstract

The invention relates to a node address coding method of a wireless communication system, the wireless communication system and equipment. The method comprises the following steps: receiving a wake-upcode combination packet sent by a master node when a slave node is in a wake-up detection state, wherein the wake-up code combination packet comprises a first address code combination packet and a second address code combination packet, the first address code combination packet comprises a plurality of first address codes, the first address codes comprise a first lead code and a second lead code,and the second address code combination packet comprises a plurality of second address codes; enabling the slave node to detect the first lead code and the second lead code of a first address code inthe wake-up code combination packet sent by the master node; continuing to detect the spread spectrum sequence of the second address code when the slave node detects that both the first lead and thesecond lead are successfully detected; and enabling the slave node to enter a formal wake-up state from a wake-up detection state when the slave node detects that the spread spectrum sequence of the second address code is successfully detected, and receiving data sent by the master node. The method can save power consumption.

Description

technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular to a node address encoding method of a wireless communication system, a wireless communication system and equipment. Background technique [0002] With the rapid development of the Internet of Things technology, its application in various fields is becoming more and more extensive, and wireless communication technology, as one of the main communication technologies of the Internet of Things, is also more and more widely used. , have put forward very high requirements for the low power consumption and long-distance transmission of the wireless communication system. A general wireless communication system is mainly composed of a master node and multiple slave nodes. [0003] In the traditional technology, the wireless communication system adopts a periodic wake-up mechanism to reduce power consumption. After the slave node wakes up automatically within th...

AI Technical Summary

Problems solved by technology

When the slave node finds that the received data does not belong to the data it wants to receive when receiving data, it will cause the problem of redundant wake-up. When there are many slave nodes in the wireless communication system, frequent redundant wake-up will greatly increase the average power consumption, resulting in increased power consumption of the wireless communication system
