有している。The communication roadbed state identification method of the present invention is a detection circuit that determines that data is disconnected by an unused signal input when the line is unused from the communication roadbed, and outputs a transmission command signal and an alarm signal, When an unused signal and the transmission command signal are input, a display signal for indicating that the line is unused is output, and when an external control signal is input, a display signal generating circuit that stops the display signal. A monitoring device that performs a disconnection display by the data when only the alarm signal is input, and displays an unused display of the line when the control signal and the alarm signal are input. I have.
次に本発明について図面を参照して説明する。第１図

う監視装置８とを有して構成される。In the present embodiment, a disconnection detecting circuit 7 which determines that data is disconnected by an unused signal 1 inputted when a line is unused from a communication base and outputs a transmission command signal 3 and an alarm signal 2; When the use signal 1 and the transmission command signal 3 are input, the AIS signal 4 for indicating that the line is not used is output. When the control signal 5 for prohibiting the transmission of the AIS signal is input from outside, the AIS signal 4 is output. The AIS generation circuit 6 stops the operation, and when only the alarm signal 2 is input, the monitor 10 displays the data interruption, and when the control signal 5 and the alarm signal 2 are input, the line is determined by the judgment circuit 11. And a monitoring device 8 for performing unused display.

ができる。With this configuration, when the disconnection detection circuit 7 determines that the data is disconnected when the line is not used, the transmission instruction is output to the AIS generation circuit, the alarm signal is output to the monitoring device 8, and the transmission is performed. The AIS generation circuit that receives the command
When the control signal for prohibiting the transmission of the IS signal is set, the AIS signal is not output to the monitoring device 8.
If the AIS signal is not output even if the line is received, the determination circuit 11 can determine that the line is unused.
以上説明したように本発明は、AIS信号の送出を禁止
