Zusammenfassung:	The present invention relates to an electricity utilization information collection system, and an NB-IoT communication module and a communication method therefor, belonging to the technical field of wireless communications. The communication method comprises: reading a communication address of an electric energy meter using a protocol; if the communication address is read successfully, setting a protocol flag for the electric energy meter; if the communication address is read unsuccessfully, reading the communication address of the electric energy meter using another protocol until the communication address of the electric energy meter is read successfully and the protocol flag is set for the electric energy meter; when data of the electric energy meter needs to be read, reading the protocol flag of the electric energy meter, and when a protocol to which the protocol flag belongs is a set protocol, uploading, according to the set protocol, the read data of the electric energy meter to a master station; and wh
