Within this application, the time interval set for interception is used on the destination device to perform interception of the collected information communicated by another controller to determine if there is a controller communicating the collected information. Here, the time interval set for interception may be set in advance according to the requirements of the application scenario.
Further, the time interval set for listening can be a time interval set in advance.
Further, to improve the listening accuracy, it is determined that another controller is provided around the target device to ensure the order of the collected information transmission of the target device, and the time interval set for listening can be determined by the number of controllers and the time slice size corresponding to each controller, as if the number of controllers is five, and the time slice size corresponding to each controller is 30ms, then the time interval set for listening is 150ms or more.

In the collected information transmission method, the collected information is intercepted, if the collected information is intercepted in the time interval for interception, through the set timing time slice, the first time slice used by the transmission device for collecting the information is identified, the second time slice used by the target device is identified, the time interval between the first time slice and the second time slice is utilized, the time interval between the second time slice is identified, the data transmission is executed in the time interval between the second time slice, the time slice used by the identified transmission device is utilized in the application, the time slice interval between the controllers is utilized, the refreshing of the corresponding time interval of the time slice used by the target device is realized, information collision caused by messy transmission orders of a plurality of controllers is prevented, and the accuracy of the information transmission is improved.
By virtue of the above method, the present application presents another collected information delivery method, which shows how to identify the time interval of using time slice two by each destination device at the beginning of the start of each controller, i.e., before the time point when each controller does not identify the corresponding time slice.
