Multistage process monitoring has recently attracted notable attention in that the statistical relationships between quality variables are taken into account. Here, we dealt with the problem of monitoring and diagnosing a two-stage production process with attribute characteristics in which the outgoing quality variable is impacted by the incoming quality variable from the first process stage....

The novelty of our approach resides in the processing of real-time power fault events from DDS to GIS web clients in three stages, as illustrated in Figure 2: 1) When the fault overlay is selected, a DDS subscriber is internally launched and connected to the GIS client in order to capture fault events, ie voltage sags, swells and other power disturbances detected at the smart meters and substat...

− The paper is to present the new DSP-based device shown in the wake of hitherto development of power quality instrumentation for power quality assessment in ship systems. The basic features of the new power quality estimator-analyser are described. Further, the design of its new commercial version is shown and discussed.

Monitoring the reliability of products in both the manufacturing and service processes is of main concern in today’s competitive market. To this end, statistical process control has been widely used to control the reliability-related quality variables. The so-far surveillance schemes have addressed processes with independent quality characteristics. In multistage processes, however, the cascade...

Power management is crucial in the monitoring of a remote environment, especially when long-term monitoring is needed. Renewable energy sources such as solar and wind may be harvested to sustain a monitoring system. However, without proper power management, equipment within the monitoring system may become nonfunctional and, as a consequence, the data or events captured during the monitoring pr...

Abstract Monitoring the quality of photovoltaic power generation in remote mountain areas is difficult, so this paper proposes a real-time online monitoring system to solve problem by using AD7606 high-precision ADC chip and STM32 single-chip microcomputer. realizes acquisition conversion three-phase data. performs wavelet transformation on collected data obtain parameters. It stores parameters...
