Abstract

PURPOSE:To allow its own station to detect line interruption in a succeeding opposite station by providing an alarm reception unit for an opposite station able to receive even a reception fault in the opposite station as an alarm to its own station. CONSTITUTION:When a transmitter 3 is faulty in the mode not raising an alarm, no fault information is sent to a central monitor station 15. However, when a receiver of an opposite station detects a fault of the transmitter 3, an alarm of the transmitter 3 is sent to an own station alarm transmission unit of an opposite station. An opposite station alarm reception unit 12 receives also the content of the alarm of the transmitter 3 because a return communication line from the opposite station to its own station is normal. Since a control line 16B is installed up to the central monitor station 15, it is discriminated that a transmission signal for the opposite station is not sent by collecting the information from the central monitor station 15. Thus, it is recognized that the opposite station is in the state of raising an alarm in the fault in which transmission of its own station is kept in the background and the line is early recovered.

を集中監視する方式であった。Conventionally, in this type of supervisory control system, a local station's alarm sending unit collectively outputs an alarm for failures in the microwave transmitting/receiving device of the local station. In addition, the local station has an opposing station alarm receiving unit that detects failures in the microwave transmitter/receiver itself of the opposing station via a wireless line. It was a method of centrally monitoring warnings.

断も検出できない状態になる欠点があった。The conventional supervisory control method described above monitors the line status at the opposing station, especially the reception failure, when there is a failure mode in which the line is disconnected due to a failure in the transmitter although no alarm is issued at the local station. Since the local station is not equipped with an alarm receiving unit for the opposing station that can receive alarms, the centralized monitoring station that monitors all of the local station and the opposing station cannot detect transmission failures of the local station. This had the disadvantage that line disconnections could not be detected.

とした場合でも、本発明を適用できる。Next, the operation of this embodiment will be explained. Assuming that the switch 5 selects the working transmitter 3, the alarm from the local alarm sending unit 6 is sent to the opposite station through the transmitter 3. The opposing station alarm receiving unit 12 receives an alarm from the opposing station. If the transmitter 3 is currently malfunctioning in a mode that does not issue an alarm, the alarm will not be transmitted to the local alarm sending unit 6, so the failure will not be transmitted to the central monitoring station 15 through the control line 16A. If the receiver of the opposite station is able to detect the failure of the transmitter 3, the alarm from the transmitter 3 is immediately transmitted to the own alarm sending unit of the opposite station. Since the communication line is normal and the signal is passing through the reverse line from the opposite station to the own station, the opposite station alarm receiving unit 12 sends out the alarm from the receiver of the opposite station, including the alarm content from the transmitter 3. The status is being received. Since the control line 16B runs to the central monitoring station 15, by collecting information from the central monitoring station 15, it can be determined that the transmission signal destined for the opposite station is not passing through. Although the centralized monitoring station has been described as having a configuration in its own station, it can also be placed in a higher-level station, such as a terminal station, to monitor alarms from relay stations including the own station and the opposing station. The present invention can be applied.

旧ができる効果がある。As explained above, even if a failure occurs on the transmitting side of the own station that does not generate an alarm, the opposite station can detect this failure and centrally monitor the alarm on the receiving side of the opposite station using the reverse line. Since the signal can be forwarded to the station, even if the failure is not visible in the transmission from the own station, the opposing station can recognize that the failure alarm has been issued and can quickly restore the line.
