ある。 FIG. 1 is a block diagram of a data transmission device showing an embodiment of this invention, and FIG. 2 is a block diagram showing a conventional data transmission device. In the figure, 1 and 2 are transmitters, 3 and 4 are receivers, 5 is a control CPU, 11, 21, 31, and 41 are designation determination circuits, 12 and 22 are analog-digital conversions, and 32 and 42 are digital-analog converters. It is a conversion circuit.

Claims

[Scope of utility model registration request]

A plurality of transmitters 1 and 2 that convert analog signals to be transmitted into pulse signals and transmit the pulse signals;
a plurality of receivers 3, 4 for restoring pulse signals from 2 to analog signals; and a plurality of receivers 3, 4 for individually specifying the plurality of transmitters 1, 2.
Each transmitter 1, 2 sends an address signal that individually specifies
and the transmitters 1 and 2 designated by the address signal in parallel.
and a control circuit 5 for controlling the exchange of the pulse signals between the receivers 3 and 4, and each of the transmitters 1 and 2 controls the transmission of pulse signals based on the address signal from the control circuit 5. Designation determination circuits 11 and 21 determine whether or not the own aircraft has been designated, and an analog signal converter that converts an analog signal to be transmitted into a pulse signal having a pulse width corresponding to the analog amount.
Each of the receivers 3 and 4 includes a designation determination circuit 31 and 41 that determines whether or not the receiver has been designated based on the address signal from the control circuit 5; Said transmitter 1
, 2 to an analog signal having an analog amount corresponding to the pulse width thereof.
