Wireless radio frequency networking communication method and apparatus

Abstract

The invention discloses a wireless radio frequency networking communication method and apparatus. A master-slave networking mode and a communication mode of a master unit asking and slave units answering are adopted. The master unit regularly summons the slave units to reply information and each slave unit successively uploads corresponding information according to general call information of the master unit. The master unit and the slave units have dormancy states. The slave units, according to end time of the duration when the general call information sent by the master unit is received, determines the moment of returning general call reply information without consistency of time between each unit, such that power consumption is reduced compared to a conventional networking communication mode. Besides, according to the technical scheme, the communication logic is simple, the communication interaction speed is improved, and the error rate is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a radio frequency networking communication method and device. Background technique [0002] In the process of UHF microwave wireless communication, information exchange between communication units includes sending, receiving, and dormant states. The network communication of each unit is generally a master and multiple slave mode. There are two main communication methods in the existing network. The first one is for the master unit to send information (calling, control, etc.), and the slave unit responds to the master unit information and replies to the corresponding information; the second is for the slave unit to send information at regular intervals, and the master unit Response to received information. [0003] In the first networking communication mode, no matter the master unit or the slave unit receives information, it must be in the receiving state...

AI Technical Summary

Problems solved by technology

[0003] In the first networking communication mode, no matter the master unit or the slave unit receives information, it must be in the receiving state, causing the receiving unit to spend a lot of time in the receiving mode, and the power loss is large; especially when there are many slave units, the power loss is even greater

The second networking communication method uses timing to start the receiving state, that is, the receiving state starts at a certain time period, and the rest of the time (except sending signals) is in the dormant state. Although the power loss is reduced, it is necessary to ensure that the main unit and The internal time of the slave unit is consistent, the hardware implementation is difficult, and the software timing will increase the power loss and the logic is complicated
