The data transmission request may be a request acquired by the measurement core 102 and requiring data transmission processing, where the data transmission request may include multiple types, for example, the data transmission request may be a measurement core request or an external request, where the measurement core request may be a request actively initiated by a measurement core inside the dual-core smart meter, specifically, the request may be a request actively initiated by the measurement core 100, such as power-on parameter and data synchronization, key pressing, timed reporting of a current instantaneous value, a minute frozen value, and the like, and the measurement core 100 may actively initiate an uplink request. The external request may be a data request initiated by a device other than the two-core smart meter and/or an internal other functional component, which may be another functional component of the two-core smart meter connected to the management core 102. The dual-core smart meter may receive the external request through the data distribution component 104, where the data distribution component 104 may be connected to an external interface of the dual-core smart meter, or may be connected to an interface of another internal component, that is, the data distribution component 104 may receive the external request from the external interface, or may receive the external request from an interface of another internal component.
