Abstract
A detection device is connected to a plurality of communication devices by a communication line. The detection device has a reception unit, a measurement unit, and a detection unit. The reception unit receives signals with prescribed pulse widths transmitted from the plurality of communication devices, respectively. The measurement unit measures the pulse widths of the signals received by the reception unit. The detection unit is configured to detect the communication device disposed near a terminal end of the communication line as a terminal-end communication device on the basis of the plurality of pulse widths measured by the measurement unit.
Claims11
A detection device connected to a plurality of communication devices by a communication line, the detection device comprising:
- a reception unit configured to receive overlap signals in which transmitted signals with prescribed pulse widths transmitted from the plurality of communication devices, respectively, and directly reaching the detection device, and the transmitted signals reflected from one of the communication devices disposed near a terminal end of the communication line overlap each other;
- a measurement unit configured to measure each of a plurality of pulse widths of the overlap signals received by the reception unit;
- and
- a detection unit configured to detect one of the communication devices disposed near the terminal end of the communication line as a terminal-end communication device on the basis of the plurality of the pulse widths of the overlap signals measured by the measurement unit.
