PURPOSE:To restore the normal communication state in a short time by providing different queuing clock periods for all devices in case of signal collision in the communication control method between distributed devices. CONSTITUTION:When a half period of a power source waveform is used as the clock period to perform communication, a signal voltage is generated in the first half and the latter of the clock period as shown in a clock E in case of signal collision. In this case, a queuing clock period corresponding to the sum of a prescribed minimum queuing clock period and an index number as which each device takes a peculiar value is defined as a control signal transmission inhibiting period of each device to make queuing clock periods after collision of all devices different from one another, and thus, the normal state is restored quickly. |
