Abstract

PROBLEM TO BE SOLVED: To conduct transmission even when it is made at the same position at the same time without any hindrance by placing alternately a transmission period and transmission small and large pause periods and changing the transmission small and large pause periods under a prescribed rule so as to allow transmission data from each transmission section to have no overlapped period without fail. SOLUTION: One transmission cycle consists of a transmission unit U and a transmission large pause period Xd and in the case of using n-sets of transmission sections, the cycle consists of alternate repetition of (n+1) times or over of the transmission period and n-times or over of transmission small pause period. Let the transmission period be T and the transmission small pause period be Xs, the transmission unit U1 of the transmission section 1, for example, consists of alternate repetition of four transmission periods T and three transmission small pause period Xs. In the case that the n-sets of the transmission sections are used simultaneously, each transmission signal is sent by (n+1) times each in the time of the transmission cycle and signals for (n-1) times or over in the transmission signals sent by (n+1) times are not overlapped on the transmission signals of the other transmission sections.

However, in data transmission, in order to avoid a transmission error, the receiving unit often reads the same data twice to make it valid data. The configuration of the above-described conventional example is such that if each transmitting unit performs transmission for one cycle or more, one or more transmission signals can reach the receiving unit without overlapping transmission signals from other transmission units. However, in order for the transmission signal to reach the receiving unit two or more times, the transmission is performed for two or more cycles.
Alternatively, it is necessary to take measures such as doubling the cycle as a whole and repeatedly transmitting data twice during the transmission period, so that the transmission speed is reduced.
