Controlling transmission of data - involves exercising control at transmitter and coding is reliably checked

摘要

The data transmission system has a transmitting station in which the information to be transmitted is converted by a control circuit (AS) and a coding system (CS) into coded data. Before being transmitted to a receiving station (STZ), the data is checked by a computer (R). Code check signals are produced in a code check circuit (PP). These are compared with the transmission data. When the signals correspond, a command is sent over computer channels (RKA, RKB) to input and output components (EA1, EA2) and the selected transmission data is connected through to transmission lines (U11, U16) under control of the control circuit (AS). USE/ADVANTAGE - For transmission between electronic signal box and rail track positioning appts. Has increased number of possible transmission code combinations. Enables accurate and efficient data transmission.
