  • Monitoring and controlling apparatus
    Patent number: 10296131
    Abstract: A monitoring and controlling apparatus includes a functional cabinet, functional units, and a control cabinet. The functional cabinet includes a plurality of frames and a door at an opening of at least a part of the frames, each frame having a predetermined accommodation size. Each functional unit is detachably accommodated in respective frame and including a circuit and a component for a function of the functional unit. The control cabinet is disposed next to the functional cabinet, and configured to monitor and control the functional units.

  • Duplexed control system and control method thereof
    Patent number: 9910754
    Abstract: A duplexed control system comprises: two control devices, whereof one is set to operate as a reserve system and the other is set to operate as a regular system; a tracking bus that connects the two control devices to enable these to exchange tracking signals; and a control transmission channel that transmits computational information of these two control devices; wherein: the control devices respectively have: an own-system state evaluation section that transmits the result of state evaluation of its own system as a tracking signal through the tracking bus to the other system; an other-system signal confirmation section that receives the tracking signal through the tracking bus from the control device of the other system and thus performs state confirmation; and a transmission channel changeover section that, if the tracking signal cannot be received through the tracking bus, effects transmission of the tracking signal to the other-system signal confirmation section of the other system, through the control tr
