Secondary random wake-up；If water meter receives the wireless parameter message that concentrator issues, the wireless parameter message is stored, and close wireless function
Can, return step S3 waits next time random wake up；If water meter does not receive the back message of concentrator in the preset time,
Then enter step S11；
Step S11: if water meter is previously to send datagram using the wireless parameter of default to concentrator, wireless function is closed
Can, return step S3 waits next time random wake up；If water meter is previously the wireless parameter that is issued using concentrator to concentrator
It sends datagram, then removes local wireless parameter, and return step S4.
Further, in step S1, it is inconsistent that the main station system controls the wireless parameter that adjacent concentrator obtains.
Further, the wireless communication function is embodied as using LoRa wireless communication module.
Further, one of concentrator respectively corresponds N number of water meter with wireless communication function.
Present invention satisfaction reaches 6 years or more working lives using battery powered wireless watermeter, and can promote unit
Wireless watermeter capacity inside cell reduces wireless transmission collision probability, improves data and acquires success rate.Water meter is used with owner
The dynamic operating mode reported above gives the correct time wireless in the open state, and other times are wirelessly in close state, not by extraneous wireless
Interference guarantees low-power consumption.Method of the invention networks comprising water meter, normal transmission, the logic to network again after transmission failure.Institute
Using unified wireless parameter when having water meter networking, be conducive to produce batch setting, the nothing of each adjacent concentrator after networking
Line parameter is inconsistent, guarantees will not wirelessly interfere with each other below adjacent concentrator.
Compared with prior art, the invention has the following beneficial effects: the present invention is wirelessly transferred mould using the LoRa of low-power consumption
Block can be effectively reduced power consumption.The cooperation for passing through main station system, concentrator and wireless watermeter simultaneously, can reduce transmission collision
Probability improves data and acquires success rate.
