Abstract:
PURPOSE:To attain quick communication by using a digital radio network between a master station and plural slave stations. CONSTITUTION:A master station calls sequentially plural slave stations by polling (steps 2, 6, 7). The call of a slave station is implemented by using a line connection (step 3), data transmission reception (step 4) and line interruption (step 5) according to a predetermined sequence. In each procedure, even when no reply comes regardless of lapse of prescribed times T1, T2, T3 (steps 8, 9, 10), a line is interrupted (step 11) and polling to a succeeding slave station is implemented (steps 6, 7).
