Data Acquisition Methods

Abstract

A data acquisition method is implemented by a receiving device that is signal-connected to multiple transmitting devices. The receiving device stores multiple transmitting device identification codes corresponding to the respective transmitting devices and multiple access sequences corresponding to multiple access frequencies. Each transmitting device identification code is included in one of the access sequences. The method includes: (A) generating and transmitting a data request to the corresponding transmitting device for each transmitting device identification code; (B) obtaining a corresponding adjustment score for each transmitting device identification code; (C) determining, based on the corresponding adjustment score, whether to change the access sequence containing the transmitting device identification code for each transmitting device identification code; and (D) when it is determined that it is necessary, deleting the transmitting device identification code from the current access sequence and adding it to another access sequence.

The third preset adjustment score is negative and greater than the first preset adjustment score.

4. The data acquisition method as described in claim 1, wherein the receiving device further stores a plurality of transmission fractions, each corresponding to an equal transmission end identification code, wherein, Step (C) further includes the following steps: (C-1) For each transmitter identifier, the receiving device obtains a transmission score to be determined based on the transmission score corresponding to each transmitter identifier and the adjustment score corresponding to each transmitter identifier; and (C-2) For each transmitter identifier, the receiving device determines whether each transmitter identifier needs to be deleted from the current access sequence based on the transmission score to be determined corresponding to each transmitter identifier, and adds each transmitter identifier to the other access sequence.

5. The data acquisition method as described in claim 4, wherein, In step (D), for each transmission terminal identifier, when it is determined that each transmission terminal identifier needs to be deleted from the current access sequence and added to the other access sequence, the receiving device also uses the transmission score to be determined corresponding to each transmission terminal identifier as the transmission score corresponding to each transmission terminal identifier; and after step (C), the following step is further included: (E) For each transmission terminal identifier, when it is determined that it is not necessary to delete each transmission terminal identifier from the current access sequence and not necessary to add each transmission terminal identifier to the other access sequence, the receiving device uses the transmission score to be determined corresponding to each transmission terminal identifier as the transmission score corresponding to each transmission terminal identifier.

6. The data acquisition method as described in claim 4, wherein the receiving device further stores multiple score intervals, each corresponding to the waiting access sequence and not overlapping with each other, wherein, In step (C-2), for each transmission end identifier, the receiving device determines whether each transmission end identifier needs to be deleted from the current sequence to be accessed and added to the other sequence to be accessed by determining whether the transmission score to be determined corresponding to each transmission end identifier is within the score range corresponding to the current sequence to be accessed.
