“…With the custom-made server, the solution was tested successfully for a 100 ms publishing interval, but the results are not so relevant for the purpose of the application because the tests were made in a wired connection. No smaller values were tested, but the authors focused on smaller time intervals and real-time concepts in work [28]. In addition, the internal sampling interval is set to request values from an OPC UA server.…”

The capacity for using mobile devices for monitoring and controlling local processes has seen rapid growth in industry for maintenance operations before and after deployment. This is especially important in the case of geographically widely-dispersed locations, such as in the case of the water sector, where processes, technologies, and local automation solutions are widely spread. Usually, the available mobile solutions are dependent on Supervisory Control and Data Acquisition (SCADA) software installed in the control rooms of water and wastewater facilities, usually without configuration possibilities. Considering the various SCADA control rooms, each focusing on a specific system, and hundreds of smaller locations accessible only with PLC and eventually a small touch screen, the dependence on local SCADA software is proving increasingly impractical. This paper presents the implementation of an easy-to-use SCADA system for the Android operating system, conceived following Industry 4.0 concepts. An OPC UA client-based architecture is proposed to cope with current interoperability standards, mobility and security across industrial processes in various domains. The design relies on a foreground service for uninterrupted communication between the application and the OPC UA client. The system is envisaged to provide notifications to alert the user when alarms are triggered, including both an independent application level alarming module and a new Alarms and Conditions based protocol level module, increasing visibility and response time for technical issues or faults, and being adaptable to both legacy and modern OPC UA specifications. The solution was tested first in the laboratory to validate the communication system with as many OPC UA structures as possible, and then in real scenarios with drinking water and wastewater systems interfacing PLC, HMI and SCADA level OPC UA servers. The tests in the real scenarios included a second-level test for water operators and engineers which accessed and monitored various processes with the developed solution, and all results proved to be satisfactory.

“…In the context of IoT application protocols, including Extensible Messaging and Presence Protocol (XMPP), Constrained Application Protocol (CoAP), Data Distribution Service (DDS), Message Queuing Telemetry Transport (MQTT), and Advanced Message Queuing Protocol (AMQP), TCP and User Datagram Protocol (UDP) are the prevalent transport protocols employed [48][49][50]. However, in the realm of IoT applications, messaging protocols often provide additional functionality not offered by transport protocols like HyperText Transfer Protocol (HTTP) and WebSocket.…”

This paper presents the implementation of a synchronous Structural Health Monitoring (SHM) framework utilizing wireless, low-cost, and off-the-shelf components. Vibration-based condition monitoring plays a crucial role in assessing the reliability of structural systems by detecting damage through changes in vibration parameters. The adoption of low-cost Micro-Electro-Mechanical Systems (MEMS) sensors in Wireless Sensor Networks (WSNs) has gained traction, emphasizing the need for precise time synchronization to schedule wake-up times of multiple sensor nodes for data collection. To address this challenge, our proposed method introduces a TCP/IP socket programming-based mimic broadcasting mechanism and a scalable sensing network controlled by a central gateway, leveraging the Raspberry Pi Python platform. The system operates using Internet of Things (IoT) concepts and adopts a star topology, where a packet is transmitted from the gateway to initiate measurements simultaneously on multiple sensor nodes. The sensor node comprises a MEMS accelerometer, a real time clock DS3231 module and Raspberry Pi Zero 2W (RPi0-2W), while the gateway employs a Raspberry Pi 4 (RPi4). To ensure accurate time synchronization, all Pi0-2W nodes were configured as Network Time Protocol (NTP) clients, synchronizing with an RPi4 server using chrony, the reliable implementation of the NTP. Through experimental evaluations, the system demonstrates its effectiveness and reliability in achieving initial time synchronization. This study addresses the challenge of achieving precise time alignment between sensor nodes through the utilization of the Dynamic Time Wrapping (DTW) method for Frequency Domain Decomposition (FDD) applications. The contribution of this research significantly enhances the field by improving the accuracy and reliability of time-aligned measurements, with a specific focus on utilizing low-cost sensors. By developing a practical and cost-effective SHM framework, this work advances the accessibility and scalability of structural health monitoring solutions, facilitating more widespread adoption and implementation in various engineering applications

“…In the era of distributed systems and cloud computing, middleware plays an important role in ensuring seamless communication, data exchange, and process management across different services. In addition, multi-protocol gateway solutions that facilitate data exchange between entities with different technical origins provide efficient data exchange in the gateway context for major automotive IoT Ethernet-based communication technologies in a variety of service-oriented architectures, requiring compatibility and real-time response capabilities [33,34]. Distributed service processing middleware also plays an important role in facilitating and managing interactions between different services and components so that they can operate consistently in a distributed environment.…”

In the world of real-time computing, there is a demand for platforms that deliver both speed and efficiency while conserving hardware resources. High reliability applications typically use dedicated platforms for their inherent reliability, but they are more expensive. On the other hand, traditional generalpurpose platforms are cheaper but suffer from wasted hardware resources when processing messages, hindering distributed processing and process monitoring. To address these limitations, this paper presents the Real-time Message Processing Framework on Multi-service Domains (RMPF), an innovative integrated platform for real-time distributed message processing on multi-service domains. The platform supports a scalable and flexible multi-layer architecture by providing modularity that allows each layer to be designed and updated independently. The interaction between each layer enables real-time distributed message processing and distributed management of multi-service processing in a city-main based, high-speed distributed environment. By accelerating message processing, using a dedicated buffer pool created for each application process, and monitoring the status of all messages in the buffer, the high reliability inherent in dedicated platforms is ensured. In addition, it minimizes the waste of hardware resources by running application processes as daemons in buffer pools. In particular, to provide domain-based multiservice, it supports RMPF grouping by task to distribute tasks to appropriate domains to eliminate system bottlenecks. It is also implemented in a modular way to achieve both scalability and adaptability through various multiservice distributed management schemes such as multiservice API, recovery, monitoring, and multiservice provisioning.INDEX TERMS Multi service, distributed message processing, unified platform, memory management, multi domain.
