As a key unit with textile coil process technology, spinning-machine's spindles composes of a braking switch, a three-phase current motor, rolling bearings and a rotary cup. Aiming at on line monitoring and fault diagnosis, a distributed monitoring system was proposed for real-time data collection and high-speed transmission. In this system, an IPC worked as an upper deck computer and many single chip processors served as bottom controllers that working status data collection and transmission can be conveniently conducted. With the features of bulk processing data and large quantities of controlled nodal points in a workshop condition, the distributed monitoring system was developed with adoption of particular approaches such as a distributed configuration with PCI bus for real time data collection and highspeed transmission, logic compression algorithm for data processing, etc. Therefore this system realizes reliable and high-speed bulk data collection, transmission and processing to meet needs of real-time monitor and control of spindle units.

In order to realize networked management of scientific instruments, a distributed monitoring system for their working status was developed. There were two solutions involved to acquire the working status data of scientific instruments. One is to detect their characteristic physical signals with sensors, and the other is to detect working parameters of their control software on their workstations with multiple ways. This paper focused on the latter one, which is convenient and low-risk to implement. In addition, Service-Oriented Architecture (SOA) was applied to design the distributed monitoring system, and there were five categories of web services offered for its flexible integration with Management Information system (MIS) or client application. Now the distributed monitoring system has been put into trial running in several universities and institutes, with many large scientific instruments monitored.

A hierarchical and distributed monitoring system in interprocess communications

A hierarchical and distributed performance monitoring tool for a rapid prototyping system for distributed algorithms is presented. The monitoring system consists of a hierarchy of monitoring units distributed over the processor nodes. The units are partitioned into several conditionally independent groups, each of which has a group leader unit. monitoring data are recorded by each individual unit and are collected and processed by the group leaders. The global picture of program behaviour is formed by the top-level unit of the hierarchy, resulting from a sequence of integrations of lower-level, partially processed data. This distributed, hierarchical nature of the monitoring system architecture offers substantial improvements in the efficiency of processing monitoring data. Furthermore, the architecture lends itself to a parallel implementation. Extensive experiments have been undertaken to make a comparison in performance between the proposed monitoring system architecture on different network topologies and a conventional, centralised monitoring system. Results show that the distributed monitoring system is scalable and that there is a significant performance improvement compared with a centralised system.

Advanced Machine Learning Functionalities in the Medium Voltage distributed monitoring system QuEEN: A Macro-Regional Voltage Dips Severity Analysis

This paper presents the integration of advanced machine learning techniques in the medium voltage distributed monitoring system QuEEN. This system is aimed to monitor voltage dips in the Italian distribution network mainly for survey and research purposes. For each recorded event it is able to automatically evaluate its residual voltage and duration from the corresponding voltage rms values and provide its "validity" (invalidating any false events caused by voltage transformers saturation) and its "origin"(upstream or downstream from the measurement point) by proper procedures and algorithms (current techniques). On the other hand, in the last years new solutions have been proposed by RSE to improve the assessment of the validity and origin of the event: the DELFI classifier (DEep Learning for False voltage dips Identification) and the FExWaveS + SVM classifier (Features Extraction from Waveform Segmentation + Support Vector Machine classifier). These advanced functionalities have been recently integrated in the monitoring system thanks to the automated software tool called QuEEN PyService. In this work, intensive use of these advanced techniques has been carried out for the first time on a significant number of monitored sites (150) starting from the data recorded from 2018 to 2021. Besides, the comparison between the results of the innovative technique (validity and origin of severe voltage dips) with respect to the current ones has been performed at the macro-regional level too. The new techniques are shown to have a not negligible impact on the severe voltage dips number and confirm a non-homogenous condition among the Italian macro-regional areas.

For the environment of using the navigation lights and its requirement, a distributed fault monitoring system on the navigation lights is designed. The three-layer structure with slave station and master station and Voyage Data Recorder is employed in the system, which can monitor broken wire fault, short circuit fault and power failure on navigation lights. The mature RS485 communication circuit is adopted in communication interface not only between the master and the slave, but also between the master and VDR (Voyage Data Recorder). The master station gets the information of all navigation lights from the slave stations, and sends these received data to VDR after being processed. The system has been successfully applied in practice, and can effectively monitor the state of the navigation lights and give the alarm information when in fault. In addition, the monitoring system can quickly and accurately trace the fault position and type, so the navigation lights can be maintain timely.

The standards related to energy management emphasize the role of the measurement activity but no exhaustive guidelines have been published for outlining requirements and architecture of a comprehensive energy efficiency monitoring system that goes beyond a simple measuring system. A monitoring system for Energy Efficiency should transform several kinds of energetic and context data into actionable pieces of information for controlling energy performance, improving operations and maintenance as well as verifying the effectiveness and the continuity of corrective actions. Eventually the energy efficiency monitoring system should be modular to be upgraded over the time and to fit the needs of any organization. This paper aims at contributing to the work of CEN-CENELEC JWG9 "Energy measurement plan for organizations" by providing background information for the development of its standards and for future work

The growing importance of state assessments in civil engineering has led to intensive research into the development of damage identification methods based on vibrations. Natural frequencies and modal shapes have garnered great interest because modal parameters are invariant of structure. Moreover, thanks to the global nature of modal parameters, their variations are not limited to the location of the damage. This is an important advantage that offers the opportunity to identify damage with sensors whose position does not have to coincide with the damaged area. The integration of MEMS sensors into structural health monitoring (SHM) systems offers a promising approach to long-term structural maintenance, especially in large-scale infrastructure. This paper presents an anomaly detection technique that analyzes raw sequential data within a statistical framework to detect damage that causes prestress loss of the tendon by exploiting a distributed monitoring system composed of six high-performance MEMS sensors. The proposed system is preliminarily evaluated to identify the frequency of the first mode, and then the proposed methodology is validated on acceleration data collected on a 240 cm beam in three different damage configurations, achieving a high detection accuracy and showing that its output can also evaluate the damage localization.
