摘要： A method for risk assessment violation monitoring during a functional safety process includes receiving parameters from a risk assessment of a portion of a system with physical devices. The parameters of the risk assessment are applicable to a safety device of a machine safety system. The safety device is configured to prevent a hazardous condition in the system. The method includes detecting a change of a condition of the safety device. The condition is indicative of a potential safety issue affecting operation of the machine safety system. The method includes comparing parameters related to the change of the condition of the safety device with the parameters from the risk assessment and sending an alert in response to determining that the change of the condition of the safety device results in a violation of the risk assessment.

摘要： A method for predicting end-of-life for a component includes determining a baseline lifetime model for a component connected to a machine functional safety system. The component is part of a system with physical devices. The method includes monitoring environmental conditions and usage conditions of the component and modifying the baseline lifetime model based on the monitored environmental and usage conditions to produce a modified lifetime model for the component. The method includes tracking a lifetime progress of the component with respect to the modified lifetime model and sending an alert in response to lifetime progress of the component reaching a lifetime threshold associated with the modified lifetime model.

摘要： A method for derivation of a machine signature includes receiving sensor information from a primary sensor, where the primary sensor is positioned to receive information from a portion of an industrial operation, and receiving sensor information from one or more secondary sensors. The secondary sensors are arranged to provide additional information about the industrial operation indicative of current operating conditions of the industrial operation. The method includes using the sensor information from the secondary sensors and machine learning to determine if the portion of the industrial operation is operating in a normal condition and, in response to determining that the portion of the industrial operation is operating normally, using sensor information from the primary sensor during the normal operating condition to derive a primary sensor signature for the sensor information from the primary sensor.

摘要： A method for using sensor data and operational data of an industrial process to identify problems includes gathering sensor data from one or more sensors sensing conditions on equipment of an industrial process, receiving command information about operational commands issued to the equipment of the industrial process, and for each sensor of the one or more sensors, comparing the sensor data with signature information for the sensor. The signature information for the sensor is relevant for operational commands issued to the equipment. The method includes determining if the sensor data of a sensor of the one or more sensors exceeds the signature information corresponding to the sensor, locating a problem with a piece of equipment of the industrial process monitored by the sensor of the one or more sensors based on the sensor data exceeding the signature information for the sensor and issuing an alert reporting the problem.

摘要： A component for light curtain alignment includes a light intensity receiver that receives a plurality of light intensity signals from beam receivers of a receiver unit of a light curtain. The light curtain includes a transmitter unit with beam transmitters arranged linearly on the transmitter unit. The light curtain includes the receiver unit with the plurality of beam receivers arranged linearly. Each beam receiver is configured to receive light from a corresponding beam transmitter. The component includes a light intensity transmitter configured to transmit, from the light curtain, the plurality of light intensity signals received by the light intensity receiver, where each light intensity signal is from one or more beam receivers, and a trip transmitter that transmits a trip signal in response to determining that a light intensity signal from a beam receiver of the plurality of beam receivers is below a trip threshold.

摘要： A method for monitoring machine operation for various machine speed and loads includes measuring vibration information at a sensor associated with a machine and an associated machine speed. The machine is a rotating machine. The method includes performing an operational frequency analysis of the vibration information and comparing results from the operational frequency analysis with a vibration signature for the machine. The vibration signature is for a machine speed that matches the machine speed of the measured vibration information. The vibration signature is one of several vibration signatures for the machine where each is for a different machine speed. The method includes identifying a potential failure mode based on a frequency range where the frequency analysis of the measured vibration information exceeds, by a threshold amount, the vibration signature of the plurality of vibration signatures that matches the machine speed, and transmitting an alert comprising the identified potential failure mode.
