Power consumption information acquisition system, NB-IoT communication module and communication method thereof

The invention relates to a power consumption information acquisition system, an NB-IoT communication module and a communication method thereof, and belongs to the technical field of wireless communication. The communication method comprises the following steps of: adopting a protocol to read a communication address of an electric energy meter, and if reading succeeds, setting a protocol mark for the electric energy meter; if the reading does not succeed, reading the communication address of the electric energy meter by adopting another protocol until the communication address of the electric energy meter is successfully read and a protocol mark is set for the electric energy meter; when the data of the electric energy meter needs to be read, reading the protocol mark of the electric energymeter, and when the protocol to which the protocol mark belongs is a set protocol, uploading the read data of the electric energy meter to a main station according to the set protocol; and when the protocol to which the prot
