in a third formula, T represents the transmission delay of a first network transmission channel between a local and a target acquisition terminal; t is t c The time node of the sending time extracted from the second data of the target acquisition terminal corresponding to the first network transmission channel is represented; t is t m A receiving time node extracted from second data of a target acquisition terminal corresponding to a first network transmission channel is shown; {} 10 Indicating that the value in parentheses is converted to decimal form.
6. The intelligent digital twin-based farmer's system of claim 5, wherein the data transmission delay calculating unit further comprises:
the data recovery subunit is used for deleting the time node at the receiving moment in the second data of the target acquisition terminal corresponding to the first network transmission channel when the judgment result of the judgment subunit is negative, and recovering the first data sent by the target acquisition terminal through the first network transmission channel;
the data receiving and storing module is specifically configured to store the first data obtained by recovering the data restoring subunit in a domestic database as the acquired data of the target acquisition terminal.
7. The digital twin based intelligent farmer's system of claim 4 or 5, further comprising:
the alarm module is used for sending network fault information to the specified client when the data transmission delay calculation unit calculates that the transmission delay of all network transmission channels between the data transmission delay calculation unit and the target acquisition terminal is greater than a preset threshold; the network fault information at least comprises a network transmission channel identifier and transmission time delay thereof.
8. The intelligent digital twin-based farmer's system of claim 1, wherein the collection terminal comprises at least: camera, transaction acquisition terminal, trace to source and sweep one of yard rifle.
