100+A2, the T value of such 800 electric energy meters is different.
The single-chip microcontroller of each electric energy meter carries out from operation is subtracted the T value of itself, until T is equal to zero, single-chip microcontroller is to LoRaWAN
Communication module is powered networking, such as networks successfully, then the electric energy meter lights the second LED light of itself.Wherein, subtract fortune certainly
It calculates to the time that result is zero and is equal to T value.In this way, 800 electric energy meters can the well-regulated completion of a platform network.
When network entry time reaches the T in 800 electric energy metersmaxWhen value, if the LoRaWAN communication module of some electric energy meter
It does not network, which cuts off the power supply to the LoRaWAN communication module, recalculates the T of the electric energy meter, then subtract certainly
It powers and networks after operation.
After electric energy meter networks successfully, LoRaWAN communication module will be communicated with single-chip microcontroller, and each electric energy meter is sharp
With frame mechanism is packaged, user is compared to data (such as current power amount, voltage, electric current, the power of care using active upload mode
With power factor etc.) it is packaged as data frame format, timing active upload to gateway；Or mould is communicated by LoRaWAN by platform
Block initiates communication request to single-chip microcontroller, and the data of response are sent to LoRaWAN communication module again by single-chip microcontroller, completes communication behaviour
Make.This mode take full advantage of gateway characteristic (uplink of each gateway has 8 receiving channels, and downlink then only one
Sendaisle), traditional passive reading is replaced with into active upload, solves the unstability in data transmission procedure, timeliness
Property the low and data problem of passively recruiting reading failure rate high；Relatively high using active upload real-time, packet loss is small, and data update
In time, user is facilitated to quickly understand electric energy meter situation.
The present invention is not limited to the above-described embodiments, for those skilled in the art, is not departing from
Under the premise of the principle of the invention, several improvements and modifications can also be made, these improvements and modifications are also considered as protection of the invention
Within the scope of.The content being not described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
