  2. Fault detection and isolation - Wikipedia

    en.wikipedia.org/wiki/Fault_detection_and_isolation

    Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...

  3. Watchdog timer - Wikipedia

    en.wikipedia.org/wiki/Watchdog_timer

    In robots and other automated machines, a fault in the control computer could cause equipment damage or injuries before a human could react, even if the computer is easily accessed. A watchdog timer is usually employed in cases like these. Watchdog timers are also used to monitor and limit software execution time on a normally functioning computer.

  4. Failure detector - Wikipedia

    en.wikipedia.org/wiki/Failure_detector

    The construction of a failure detector is an essential, but a very difficult problem that occurred in the development of the fault-tolerant component in a distributed computer system. As a result, the failure detector was invented because of the need for detecting errors in the massive information transaction in distributed computing systems.

  5. On-board diagnostics - Wikipedia

    en.wikipedia.org/wiki/On-board_diagnostics

    The ability to use multiple software programs adding flexibility; The identification and clearance of fault code; Data shown by intuitive graphs and charts; The extent that a PC tool may access manufacturer or vehicle-specific ECU diagnostics varies between software products [42] as it does between hand-held scanners.

  6. Fault management - Wikipedia

    en.wikipedia.org/wiki/Fault_management

    Ideally, a fault management system should be able to correctly identify events and automatically take action, either launching a program or script to take corrective action, or activating notification software that allows a human to take proper intervention (i.e. send e-mail or SMS text to a mobile phone). Some notification systems also have ...

  7. Automatic test pattern generation - Wikipedia

    en.wikipedia.org/wiki/Automatic_test_pattern...

    ATPG (acronym for both automatic test pattern generation and automatic test pattern generator) is an electronic design automation method or technology used to find an input (or test) sequence that, when applied to a digital circuit, enables automatic test equipment to distinguish between the correct circuit behavior and the faulty circuit behavior caused by defects.

  8. Fault tolerance - Wikipedia

    en.wikipedia.org/wiki/Fault_tolerance

    This is usually handled with a separate "automated fault-detection system". In the case of the tire, an air pressure monitor detects the loss of pressure and notifies the driver. The alternative is a "manual fault-detection system", such as manually inspecting all tires at each stop. Interference with fault detection in another component.

    Time-domain reflectometer for cable fault detection A time-domain reflectometer ( TDR ) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses .
