PURPOSE:To control a mobile body such as electromotive rack efficiently, by automatic control of a mobile body at a fixed station side through a control reference issued by the operator at a mobile station side. CONSTITUTION:An audio signal from a microphone 13 at a mobile station 10 side is inputted to a radio set 11 and transmitted through an antenna 12. At a fixed station 20, the transmission is received at a radio set 21 through an antenna 22 and the content is recognized at an audio recognition device 23. A response signal generator 24 generates the audio signal with the same content as that recognized by the device 23 from the information by the device 23 and transmits it from the set 21. At a mobile station 10, the signal is reproduced by a head phone 14 or a speaker 15 and when it is confirmed that it is the same as the original audio signal, a control permission signal is transmitted. In the fixed station 20, when this is recognized of audio at 23, an electromotive rack 1 is controlled 25. |
