- the failure monitoring function unit 12 determines whether or not a failure has occurred in the apparatus main function unit 15 (step S201). If it is determined that no failure has occurred, the failure monitoring function unit 12 determines whether the wireless maintenance communication has been disconnected (step S202). If the wireless maintenance communication is not disconnected in step S202, the maintenance operation by the maintenance terminal 14 is being performed, so the failure monitoring function unit 12 repeats steps S201 and S202.

If the wireless maintenance communication is not disconnected, the failure monitoring function unit 12 repeats step S303 and maintains the activated state of the wireless maintenance communication function unit 13.
- step S303 If it is determined in step S303 that the wireless maintenance communication is disconnected, the maintenance operation by the maintenance terminal 14 is not performed, so the failure monitoring function unit 12 designates the specified time after the wireless maintenance communication function unit 13 is activated. It is determined whether or not elapses (step S304). If the designated time has not elapsed, the failure monitoring function unit 12 repeats steps S303 and S304. Thereafter, when it is determined in step S304 that the specified time has elapsed, the failure monitoring function unit 12 invalidates the wireless maintenance communication function unit 13 (step S305). Thereafter, the failure monitoring function unit 12 waits for a predetermined time (step S306). After step S306, the failure monitoring function unit 12 repeatedly executes the above steps S301 to S306.
- the standby time in step S306 means a guard time for preventing abnormal operation of the wireless maintenance communication function (ie, a time during which the wireless maintenance communication function should not be re-enabled).
- step S301 since the processing after step S301 is repeated after the wireless maintenance communication function unit 13 is invalidated in step S305, the wireless maintenance is performed in a state where no failure has occurred in the apparatus main function unit 15.
- the communication function unit 13 is maintained in a disabled state.
- step S303 when a failure occurs in the apparatus main function unit 15, whether or not the wireless maintenance communication is disconnected in step S303 after enabling the wireless maintenance communication function unit 13 in step S302. If the wireless maintenance communication is not disconnected, step S303 is repeated. Thereby, during the maintenance work, the failure monitoring function unit 12 maintains the wireless maintenance communication function unit 13 in an activated state until the maintenance work is completed.
- the control method of the third embodiment is the same as that of the second embodiment. Further, in the third embodiment, the condition determination regarding the elapse of the designated time is performed in step S304, and the failure monitoring function unit 12 secures the designated time as the maintenance connectable time after enabling the wireless maintenance communication function unit 13. .
- the maintenance workability is improved when the failure state of the apparatus main function unit 15 is maintained. Since the failure monitoring function unit 12 disables the wireless maintenance communication function unit 13 in step S305 and waits for a predetermined time in step S306, an unnecessary activation time of the wireless maintenance communication function unit 13 before the start of maintenance work. Can be reduced. In the third embodiment of the present invention, the maintenance workability is improved when the failure state of the device function unit 15 continues, and the activation time of the unnecessary wireless maintenance communication function unit 13 before the start of the maintenance work is reduced. Security risk can be reduced.

Description
本願は、2011年3月30日、日本国に出願された特願2011-73804号に基づき優先権を主張し、その内容をここに援用する。
図2において、屋外障害監視装置11が処理を開始すると、障害監視機能部12は装置主機能部15に障害が発生しているか否かを判定する(ステップS101)。装置主機能部15に障害が発生していないと判定されると、障害監視機能部12は無線保守通信機能部13を無効化する(ステップS102)。このように、装置主機能部15に障害が発生していない場合、障害監視機能部12はステップS101とS102を繰り返し、無線保守通信機能部13を無効化する。
図3において、屋外障害監視装置11は処理を開始すると、障害監視機能部12は装置主機能部15に障害が発生しているか否かを判定する(ステップS201)。障害が発生していないと判定されると、障害監視機能部12は無線保守通信が切断されているか否かを判定する(ステップS202)。ステップS202で無線保守通信が切断されていない場合、保守端末14による保守作業が実施中であるため、障害監視機能部12はステップS201とS202を繰り返す。一方、ステップS201において障害が発生していると判定した場合、障害監視機能部12は無線保守通信機能部13を有効化する(ステップS204)。無線保守通信機能部13の有効化とは、電源供給をオンして無線通信を可能とする制御を意味する。また、ステップS202において、無線保守通信が切断されていると判定される場合、保守端末14による保守作業は実施されていないので、障害監視機能部12は無線保守通信機能部13を無効化する(ステップS203)。この場合、障害監視機能部12はステップS201、S202、及びS203を繰り返す。
図4において、屋外障害監視装置11の処理が開始されると、障害監視機能部12は装置主機能部15に障害が発生しているか否かを判定する(ステップS301)。障害発生と判定されると、障害監視機能部12は無線保守通信機能部13を有効化する(ステップS302)。その後、障害監視機能部12は保守端末14との無線保守通信が切断されているか否かを判定する(ステップS303)。無線保守通信が切断されていなければ、障害監視機能部12はステップS303を繰り返して、無線保守通信機能部13の有効化状態を維持する。ステップS303で無線保守通信が切断されていると判定された場合、保守端末14による保守作業は実施されていないので、障害監視機能部12は無線保守通信機能部13が有効化されてから指定時間が経過したか否かを判定する(ステップS304)。指定時間経過していなければ、障害監視機能部12はステップS303とS304を繰り返す。その後、ステップS304で指定時間経過したと判定されると、障害監視機能部12は無線保守通信機能部13を無効化する(ステップS305)。その後、障害監視機能部12は所定時間待機する(ステップS306)。ステップS306の後、障害監視機能部12は上記のステップS301~S306を繰り返し実行する。尚、ステップS306の待機時間は無線保守通信機能の動作異常などを防止するためのガード時間(即ち、無線保守通信機能を再有効化してはならない時間)を意味する。
