The number of times of link conflicts may be times of time conflicts between the link and other links. The link conflict time may be the total duration of time conflicts between the link and the other links. The link time utilization may be information such as the used time of the link, or the idle time, or the ratio of the used time to the total available time.

When the link and other links transmit information at the same time, that is, the slave and other slaves send information to the master at the same time or the master sends information to two slaves at the same time, then There is a time conflict between the link and this other link. The other link may be a link between another slave device and the master device.

In the link processing method, the number of time conflicts between the link and other links during the preset time period, that is, the number of link conflicts, and the time when the link conflict occurs, that is, the link conflict time can be counted.

Since the master device is the scheduling core of multiple slave devices, the master device can count the status of each link among the multiple links between the master device and multiple slave devices within the preset time period. , Not limited to the link between the slave device and the slave device, to determine status information of each link among the multiple links.

The communication time, and the adjustment parameter is determined according to the communication time in each interval on the link and a preset communication time of the link.

The preset communication time of the link may be the time corresponding to the link bandwidth configured by the application layer according to the transmission bandwidth requirement of the link.

The master device can determine whether the number of link collisions is greater than or equal to a preset number of times. If the number of link collisions is greater than or equal to a preset number of times, it can be determined that the link state information meets the preset condition, and the chain is required to The communication time of the link is adjusted; conversely, if the number of link conflicts is less than the preset number, it can be determined that the link state information does not meet the preset condition, and there is no need to adjust the communication time of the link.

If the link state information includes: link conflict time, the preset condition is that the link conflict time is greater than or equal to the preset time. The master device can determine whether the link conflict time is greater than or equal to a preset time, and if the link conflict time is greater than or equal to a preset time, then it can be determined that the link state information meets the preset condition, and the link needs to be The communication time of the link is adjusted; conversely, if the link conflict time is less than the preset time, it can be determined that the link state information does not meet the preset condition, and there is no need to adjust the communication time of the link.

If the link state information includes: link time utilization, the preset condition may be that the link time utilization is less than or equal to the preset utilization.

Conversely, if the link time utilization is less than the preset time, it can be determined that the link has less idle time and its utilization is higher. If the link status information does not satisfy the preset condition, there is no need to adjust the communication time of the link.

S504. If the link state information meets the preset condition, the master device sends the adjustment instruction to the slave device.

If the link state information satisfies the preset condition, the master device needs to adjust the communication time of the link, and then triggers the adjustment, that is, sends the adjustment instruction to the slave device.

As shown in Figure 7, during the initial establishment of link 1 and link 2, the communication time of link 1 is Time 1 within an interval, and the communication time of link 2 and the communication time of link 1 are partially Overlapping, which makes link 1 and link time conflict. Therefore, in order to avoid the time conflict between link 1 and link 2 in the next interval, the communication time of link 1 or link 2 needs to be adjusted.

This method may be triggered by the master device or the slave device 1 or the slave device 2 to adjust the communication time. For a specific implementation process, refer to the foregoing, and details are not described herein again.

In this example, statistics on the state information of link 1 and link 2 within an interval can be made, and based on the state information of the link, the length of the data packets transmitted on the link, and the number of packets transmitted on the link. Information such as the type of the physical header determines the communication time required in each interval on the link, and determines the adjustment parameter based on the communication time in each interval on the link and the preset communication time for the link, such as The time offset shown in FIG. 7. In this method, for example, by comparing the data packets on link 1 such as T1 and R1 and the data packets on link 2 such as T2 and R2, it can be known that the communication time of link 1 cannot meet its transmission requirements, and it is necessary to The time offset adjusts the initial communication time of the link 2 so that the communication time of the link 1 is adjusted to Time 2 as shown in FIG. 7, thereby effectively avoiding the arrival of the link 1 and the link 2 in the next interval. Time Conflict.
