PURPOSE:To implement almost consecutive data transmission when the transmission of data exceeds a transmission limit time and to attain excellent data reception at all times. CONSTITUTION:A microcomputer 27 monitors the reception state of a 1st radio equipment 23 and a 2nd radio equipment 24 and applies switching control to a reception data changing-over switch 30 to select a radio equipment whose reception state is always excellent at all times. The microcomputer 27 interrupts tentatively the control of the reception data changing-over switch 30 at the data transmission when the radio equipment sending the data is close to a transmission limit time to allow a radio equipment not in the data reception state to retrieve a dead channel and allows a radio equipment not in the data transmission to occupy the dead channel. When the radio equipment during data transmission reaches the transmission limit time, the microcomputer allows the radio equipment not in data transmission state to start data transmission using the dead channel. |
