いう欠点があった。Because data is transmitted between each communication station (1) to (8) as described above, even in a system where communication stations with high communication frequency and communication stations with low communication frequency coexist, for example, communication station (1) to (8) ) and SLB communication station 121, and between communication station (3) and communication station (41), even if communication frequency is high and there is almost no communication between other groups, regardless of the communication frequency. Since all communication stations are connected within one loop-shaped transmission path and slots must be allocated for all communication stations in the transmission frame, the transmission frame becomes long and the frame rotation speed is slow. There was a drawback.

データ伝゛送装置金得ること全目的とするものである。This invention was made in order to eliminate the drawbacks of the conventional device as described above, and it is possible to achieve efficient data transmission by classifying between communication stations with high communication frequency and between stations with low communication frequency. The entire purpose of the device is to earn money.

3) Since it does not affect slots +1 and 2 in the transmission frame circulating in each session, communication between other communication stations on the same loop-shaped transmission path can be carried out freely, and at the same time. If it is necessary to transmit data from the communication station (5) to the communication station (2), the loop-shaped transmission line (22)
Transmission similar to the above is possible if data is set as a total communication (iIj 8121) to slot valve 1 in the transmission frame that is circulating k times.

る。In the above embodiment, although two communication stations are installed on one loop transmission path, the same operation can be performed even if the number of communication stations is more than that. Although all examples have been shown in which one slot is provided to another loop-shaped transmission path, the same effect can be expected even if the communication frequency between loops increases.

という効果がある。As explained above, this invention connects communication stations with a large amount of communication with a loop-shaped transmission line, and connects the loop-shaped transmission lines in a star shape with an inter-loop communication control device, thereby reducing the amount of transmission between the communication stations. Accordingly, there is an effect that efficient and rapid data transmission can be obtained.
