容位置によって送信権獲得に偏りがあるという問題点が
ある。In the transmission right control method in the conventional ring-type transmission device described above, since the transmission path is in a ring shape, the transmission right is transferred according to the order in which the nodes are accommodated at the most troublesome time. However, once an empty frame has passed, it takes a long time for the transmission right to be transferred from the node that issued the empty frame to the node furthest in the frame flow direction. There is a problem in that acquisition of transmission rights is biased depending on location.

An object of the present invention is to provide a transmission right control method in a ring-type transmission device that can be used in a ring-type transmission device.

とを確認して送信権を得る構成である。The transmission right control method in the ring type transmission device of the present invention is as follows:
A field for recording the number of transmission right acquisition failures is provided in a frame that circulates within the ring transmission path to record the number of transmission right acquisition failures for each node accommodated in the ring transmission path, and all the nodes The node is equipped with a transmission right acquisition determination device that determines whether the right acquisition is possible, and a transmission right acquisition failure recording device that records the number of transmission right acquisition failures in the transmission right acquisition failure number recording field. When received, the transmission right acquisition determination device refers to the transmission right acquisition failure count record field;
The configuration is to obtain the transmission right by confirming that there is no node that has failed to acquire the transmission right more often than the own node.
