A low power consumption wireless radio frequency network networking method

Abstract

The present invention provides a low-power wireless radio network networking method, which includes the following steps: step S1, the host goes online, and starts to realize the establishment of a wireless radio network; step S2, the host cyclically sends broadcast messages; step S3, the slave continues to detect Listen, after listening to the broadcast message, receive and analyze the broadcast message, and obtain the authorized communication number; step S4, the slave sends a login message; step S5, after the host receives the login message, judge the Log in the internal logic of the message, and fill in the address of the slave in the position corresponding to the authorized communication number inside the host until the confirmation is correct; step S6, the slave sends data through the position corresponding to the authorized communication number. The slave without data transmission in the present invention can be in a dormant state for a long time, and the average dormancy cycle duty ratio exceeds 97%, thereby effectively reducing the communication delay; the master does not need to send a wake-up message, the communication reliability is high, and the power consumption is low. The networking speed is fast.

Description

technical field [0001] The invention relates to a networking method, in particular to a low power consumption wireless radio frequency network networking method. Background technique [0002] In the existing electric power industry, the power automation terminal products need to use radio frequency communication between the master and slave machines. The host can obtain high-power stable power supply through solar energy, CT and PT, etc., but in many occasions, the slave is installed on the high-voltage power line, and can only rely on its own battery for power supply, and the battery cannot be replaced. Therefore, it is necessary to design a low power consumption uA level Wireless communication scheme; existing low-power communication schemes mostly use the simple wireless control mode of long sleep→wakeup→receive→re-sleep. [0003] The above-mentioned wireless control mode has the following disadvantages: first, the sleep time of the slave is too long, which will cause a ...

Problems solved by technology

The host can obtain high-power stable power supply through solar energy, CT and PT, etc., but in many cases, the slave is installed on the high-voltage power line, and can only rely on its own battery for power supply, and the battery cannot be replaced. Therefore, it is necessary to design a low-power consumption uA level Wireless communication scheme; the existing low-power communication scheme, mostly through the wireless control mode of simple long sleep→wake up→receive→re-sleep

[0003] The above-mentioned wireless control mode has the following disadvantages: first, the sleep time of the slave is too long, which will cause a large communication delay; second, every time the master sends information to the slave, it needs to send a wake-up report with a long wake-up time Third, because it takes a long time for the host to send information to the slave, the host cannot receive the message for a long time when sending data, resulting in low communication reliability and average data transmission rate; fourth, the host sends When waking up a message, non-target slaves will also be woken up for a long time, resulting in a significant increase in power consumption of non-target slaves
