Abstract

PURPOSE:To enable to deliver the information of multi-items in a short time even for high speed mobile body, by the transmission and reception with the information code control by frequency divided clock pulse and two phase phase shift modulation wave control. CONSTITUTION:When transmission is made from the receiver 14 via the loop coupler 15, it is received at the loop coupling unit 16 at transmission side, the power supply 17 is started, and the power supply for the information transmitter 18 and the information input encoder 19 is active. Thus, the transmitter 18 controls the encoder 19 by taking the frequency f from the coupling unit 16 and returns the two phase phase shift modulation wave signal by binary code to the reception side. The encoder 19 performs digital coding for multi-item information, addition of frame synchronous code and delivery control of information code. Further, the two phase phase shift modulation signal delivered to the coupling unit is inputted to the receiver 14, where phase discrimination is made, and the detection of the frame synchronous code and the information code based on it are outputted.
