  • Patent number: 9922738
    Abstract: A traveling reactor power monitoring system includes a drive control unit configured to drive a motor and move a traveling probe in a guide tube by driving the motor, a torque sensor configured to measure a drive torque of the motor, and a drive torque monitoring unit that generates an alarm when the measured drive torque exceeds a predefined upper threshold, and that bypasses generating the alarm for a predefined bypass time, the predefined bypass time starting at a time of starting driving the motor.

  • Patent number: 9305670
    Abstract: A TIP monitoring control equipment has: a process computer, a TIP control panel, and data transmitting unit. The process computer includes a operation input unit, a TIP scanning unit, a first TIP level data transmitting and receiving unit, and a TIP level data storage unit. To a first TIP level data transmitting and receiving unit, an LPRM level signal, an APRM level signal and TIP level data accumulated in the TIP control panel are input in synchronization with a TIP position signal. The TIP control panel includes a TIP driving control unit, a TIP level processing unit, a TIP position processing unit, a TIP level data accumulation unit and a second TIP level data transmitting and receiving unit. The second TIP level data transmitting and receiving unit transmits TIP level data accumulated in the TIP level data accumulation unit to the process computer via the data transmission unit.

  • Patent number: 8331521
    Abstract: According to an embodiment, a digital process type monitor device includes a plurality of modules and a mother board connected to each of the modules. Each module includes: a base board connected to a connector and having an FPGA for main control and an IPGA for sub board control mounted thereon; and a sub board for a main-machine I/F process, having an FPGA for an I/F process mounted hereon. Each sub board has storage devices for storing man-machine I/F information on the sub board. Each of the FPGA writes transmission data into a predetermined region of a transmission area and has a common transmission protocol to share the transmission data between the respective modules.
