INSPECTION SYSTEM, INSPECTION DEVICE AND INSPECTION METHOD
To provide an inspection system, an inspection device and an inspection method which can reduce a risk generated when a control operation based on a closing command is performed.SOLUTION: An inspection system is an inspection system of performing inspection of a controlled object where a higher-level station and a plurality of slave stations are connected to each other via a communication line. The inspection system includes an inspection execution unit, a switching unit, and a relay control unit. When receiving a control signal indicating an inspection instruction from the higher-level station, the inspection execution unit outputs an inspection signal for executing inspection. The switching unit can switch an output line of the control signal for operating the controlled object to an output line of reversing from the output line to the controlled object to an own station. When receiving the inspection signal from the inspection execution unit, the relay control unit performs switching of reversing the control signal from the higher-level station for the switching unit.SELECTED DRAWING: Figure 5
【課題】閉鎖指令に基づく制御操作がなされた場合に生じるリスクを軽減することができる点検システム、点検装置及び点検方法を提供することである。【解決手段】実施形態の点検システムは、上位局と複数の子局が通信回線を介して接続された制御対象の点検を行う点検システムである。点検システムは、点検実行部と、切替部と、リレー制御部とを持つ。点検実行部は、前記上位局から点検指示を示す制御信号を受信すると、点検を実行するための点検信号を出力する。切替部は、前記制御対象を動作させるための制御信号の出力ラインを、前記制御対象への出力ラインから自局へ折り返す出力ラインに切替可能である。リレー制御部は、前記点検実行部から前記点検信号を受信すると、前記切替部に対して、上位局からの前記制御信号を折り返すように切替を行う。【選択図】図５
