For example, after a real-time message to be uploaded to the internet of things gateway is generated, the message length of the real-time message is determined, and the message capacity of a single message is determined when the message information is uploaded to the internet of things gateway.
Furthermore, the real-time message is segmented according to the preset message capacity of the single message information to obtain a plurality of real-time message fragments, and the data length of each real-time message fragment is smaller than the message capacity of the single message information.

Optionally, when the real-time message is segmented, the length of the real-time message segment obtained by the previous segmentation is matched with the message capacity of the message information to reduce the number of the generated message information, when the remaining capacity of the message information is detected, because the remaining capacity of the previous message information is small, the remaining capacity of the message information can be ignored, only the message information corresponding to the last real-time message segment of the real-time message is detected, and at the moment, the last message information can have more remaining capacity, so that the accommodated regular message segments are increased.
S103: and intercepting a regular message according to the residual capacity of each message information to obtain regular message fragments, adding the regular message fragments to the tail of the corresponding message information, and sequentially sending the message information to the gateway of the Internet of things.

S1002: and determining a data reporting strategy based on the current power supply mode, wherein the data reporting strategy comprises an efficiency priority strategy and an energy-saving priority strategy which respectively correspond to the external power supply mode and the battery power supply mode.
For example, before determining the message length of a real-time message to be sent to the gateway of the internet of things, the current power supply mode of the node data transmission control device of the internet of things is determined. The power supply mode that this embodiment provided includes external power supply mode and battery power supply mode, wherein under external power supply mode, thing networking node data transmission controlling means supplies power through external power supply (for example directly supply power by external power supply, perhaps when charging for the battery through external power supply, supply power for each components and parts through external power supply, thing networking node data transmission controlling means's work can not or very little consumption battery power), and under battery power supply mode, thing networking node data transmission controlling means is supplied power by built-in battery, thing networking node data transmission controlling means's work will consume built-in battery's electric quantity.

Specifically, after a real-time message which needs to be uploaded to the internet of things gateway is generated, the message length of the real-time message is determined, and the signal strength information of the currently connected internet of things gateway is determined. After the signal strength information of the currently connected Internet of things gateway is determined, the message capacity of the single message information is determined according to the signal strength information. It can be understood that the stronger the signal strength information, the larger the corresponding message capacity.
In a possible embodiment, the determining the message capacity of the single message information based on the signal strength information provided by this embodiment includes:

After the real-time messages are respectively added into the message information in a fragmentation mode, whether regular messages waiting for uploading to the gateway of the Internet of things are stored or not is determined, if yes, the step S208 is skipped, and if not, the step S207 is skipped.
S207: and directly and sequentially sending the message information to the gateway of the Internet of things.
And if no regular message needs to be uploaded to the Internet of things gateway, directly and sequentially sending message information to the Internet of things gateway.
