Abstract

PURPOSE:To ensure a simultaneous control through using an item of remote monitor control device that is usually used, by measuring the time during which the signal returned from a receiving terminal side is received after transmission of a control signal. CONSTITUTION:The start signal of control is supplied through a terminal 10 to be applied to a code transmitting part 1 via a reproduction control part 9. In this case, a time limit circuit 6 is started. The start signal is turned into a series code at the transmitting part along with other input signals to be transmitted periodically to a communication line 13. This series code is received at a code receiving part 3 to be turned into a parallel signal and then supplied to a code transmitting part 4 and a time limit circuit 5. The circuit 5 delivers a control signal to a terminal 12 after a time that is set previously. On the other hand, the signal supplied to the part 4 is delivered from at ransmission terminal side receiving part 2 via a communication line 14. At the transmission terminal side, the time from a start of transmission to a reception is measured at a return time measuring part 7. In case the return time is not within a prescribed value, the control signal is discontinued temporarily. Then a similar action is repeated again. While in case the return time is within a prescribed value, the output of the circuit 6 is delivered as it is in the form of a control output.
