| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an alarm notification system capable of easily monitoring the state of an onboard amplifier. SOLUTION: In two coaxial cables P and A, a power is supplied with only one, while the other is used to notify an alarm from an onboard amplifier 20 to a monitoring device 10 using a constant current value. A plurality of kinds of alarms, such as miner alarm and major alarm, are discriminated by changing the constant current value. The monitoring device 10 measures a voltage at both ends of a terminal resistor of the coaxial cable A to discriminate a current value for confirming kind of alarms. COPYRIGHT: (C)2007,JPO&INPIT |
