PURPOSE:To manage and control a BS period of a slave station and the off-time of a power supply of the slave station at a master station by identifying the off-time of the power supply at the slave station based on a specific number in a BS time slot sent from the master station, calculating the length of the power-off time so as to turn on/off the power supply. CONSTITUTION:The system consists of a battery saving(BS) specific number generating circuit 11, a multiplex circuit 12, a transmission section 13, a reception section 21, a BS specific number detection circuit 22 and a BS control circuit 25. Then a master station sends n-set of specific numbers to a BS time slot in common to n-set of all slave stations within 1BS period to the slave station, the slave station identifies a power-off time based on the specific number in the BS time slot, calculates the length of the power-off time to turn on/off the power. Thus, the BS period of the slave station and the power-off time of the slave station are managed and controlled by the master station. |
