And protocol encapsulation, form standard DL T645-2007 messages, data directly send electric energy meter to by serial ports.
(2) data uplink flow
LoRa built-in modules are communicated by serial data bus and electric energy meter, after reading the data on serial bus, into
LoRa the FSK numbers that the judgement of row agreement and the data for arriving copy reading will be ready for sending by LORAWAN agreement framings, main control module
1278 radio-frequency module of radio-frequency module is sent to according to by SPI, and gateway is sent the data to by 1278 radio-frequency modules.
A kind of embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
