Filed: 1987-02-25
Abstract: PURPOSE:To attain information communication having good reliabity and to obtain an economical information communicating system using the merit of a radio communication and communicating alternately a bit information by utilizing a wire channel when the condition of the radio communication is worsened. CONSTITUTION:When a radio communicating condition is deteriorated and a bit error rate is increased for a long period, it is judged that the radio communicating condition is bad. As the result, a switch 1 is conducted and a receiver change-over switch 9 is switched to a wire receiver 14 side. Simultaneously, the information of the switching control is informed to an opponent side and the information communication is started through a wire channel 13. When it is confirmed that the wire communicating condition is normally recovered, the receiver change-over switch 9 is turned to a wireless receiver 8 side simultaneously with the interruption of the switch 11. The information transmission by the radio is started and the information communication is stopped through the wire channel 13. Thus, even when the deterioration, etc., of the signal quality in the radio communication occur, a stable channel can be always secured and the trouble does not occur at the business processing.
