A system and a method are provided including a controller for a refrigeration or HVAC system having a compressor rack with at least one compressor. The controller communicates with a tracking module configured to diagnose health of a compressor in the compressor rack. In response to rated performance data for the compressor being unavailable, the tracking module is configured to generate baseline data for the compressor and to diagnose health of the compressor by comparing operational data of the compressor to the baseline data for the compressor. In response to the rated performance data for the compressor being available, the tracking module is configured to diagnose health of the compressor by comparing the operational data of the compressor to the rated performance data for the compressor.

A method for commissioning a sensor series circuit configured in a daisy chain topology. A second sensor being downstream from a first sensor. The method includes furnishing a first switch signal to the first sensor to close the first switch, the first switch signal being furnished in response to a successful initialization of the first sensor, monitoring a function of the second sensor during initialization of the second sensor to ascertain whether the second sensor exhibits a fault upon initialization or is initialized correctly, and to furnish a fault signal if it is ascertained that the second sensor exhibits a fault upon initialization; and outputting a suppression signal to the first sensor if the fault signal has been furnished, to prevent the first switch from being closed.

An arc detection and intervention system for a solar energy system. One or more arc detectors are strategically located among strings of solar panels. In conjunction with local management units (LMUs), arcs can be isolated and affected panels disconnected from the solar energy system.

A petrochemical plant or refinery may include equipment such as pumps, compressors, valves, exchangers, columns, adsorbers, or the like. Some petrochemical plants or refineries may include one or more sensors configured to collect operation information of the equipment in the plant or refinery. A faulty condition of a process of the petrochemical plant may be diagnosed based on the operation of the plant equipment. A diagnostic system, which may receive operation information from the one or more sensors, may include a detection platform, an analysis platform, a visualization platform, and/or an alert platform.

A diagnostic system is provided for diagnosing a process of a plant, using a computing device. A detection unit automatically detects a faulty condition of the process based on a plurality of readings of parameters or measurements associated with the faulty condition for alerting an operator. An analysis unit determines an operating status of the plant based on the plurality of readings of parameters or measurements. A display device graphically links the faulty condition with the plurality of readings of parameters or measurements. A visualization unit displays the operating status of the plant with the readings of parameters or measurements using an alert dashboard grouping related data based on a source of the data for meaningfully illustrating relationships of the displayed data. An alert unit automatically generates a warning message based on the plurality of readings of parameters or measurements to inform the operator of the faulty condition.

A method for monitoring and diagnosing anomalies in auxiliary systems of a gas turbine implemented using a computer device coupled to a user interface and a memory device, the method including storing a plurality rule sets in the memory device, the rule sets relative to the auxiliary systems of the gas turbine, the rule sets including at least one rule expressed as a relational expression of a real-time data output relative to a real-time data input, the relational expression being specific to parameters associated with the auxiliary systems of the gas turbine, receiving real-time and historical data inputs from a condition monitoring system associated with the gas turbine, the data inputs relating to process parameters associated with the auxiliary systems of the gas turbine, and estimating values for at least some of the parameters associated with the auxiliary systems of the gas turbine using the received inputs.

A method for presenting operational information of a mobile platform includes collecting diagnostic data and travel route data associated with an operation of the mobile platform, and integrating the travel route data with the diagnostic data for presentation. The diagnostic data includes at least one of platform diagnostic data or remote control data. The remote control data is generated by a remote controller associated with the mobile platform or generated by a computer device.

Methods and systems for collecting and analyzing data for managing and maintaining buildings are provided. An example method commences with collecting a plurality of data points from a plurality of equipment pieces associated with at least one building. The plurality of data points are associated with an operation of the plurality of equipment pieces. The method continues with analyzing the plurality of data points based on predetermined criteria. The analysis includes determining whether one or more rules of a plurality of rules are met by the plurality of equipment pieces. The method further includes determining, based on the analysis, that one or more equipment pieces of the plurality of equipment pieces do not meet the one or more rules. The method then continues with generating an alert associated with the one or more equipment pieces based on the determination that the one or more rules are not met.

Disclosed is a system for managing a vehicle battery that is chargeable/dischargeable and stores energy for driving a vehicle driving motor. The system for managing the vehicle battery as disclosed includes a controller that measures a polarization voltage of each of a plurality of battery cells in a vehicle battery after charging of the vehicle battery is terminated, and determines whether each of the plurality of battery cells is abnormal based on the measured polarization voltage.

An electrical discharge machine includes: a machining power supply having a plurality of different circuit states, and configured to be capable of being set to one circuit state of the plurality of circuit states by switching at least one of electrical connection and electrical setting; a state determining unit configured to, when each of the plurality of circuit states is set as the circuit state of the machining power supply, determine whether or not the set circuit state is normal; a failure portion specifying unit configured to specify a failure portion of the machining power supply based on a determination result with respect to each of the plurality of circuit states obtained by the state determining unit; and a reporting unit (a display unit or the like) configured to report the failure portion specified by the failure portion specifying unit to an operator.
