“…Given that the converter layer of the proposed middleware must receive messages that comply with standard protocols for smart grids and translate them into a format recognised by the WSN, we proposed a memory mapping to facilitate this translation in previous research [ 62 ]. This mapping is based on an address relationship in the memory area, which we called the smart-grid poll, and further details can be found in [ 62 ]. Other smart-grid protocols can be easily adapted to the middleware.…”

At present, the standardisation of electrical equipment communications is on the rise. In particular, manufacturers are releasing equipment for the smart grid endowed with communication protocols such as DNP3, IEC 61850, and MODBUS. However, there are legacy equipment operating in the electricity distribution network that cannot communicate using any of these protocols. Thus, we propose an infrastructure to allow the integration of legacy electrical equipment to smart grids by using wireless sensor networks (WSNs). In this infrastructure, each legacy electrical device is connected to a sensor node, and the sink node runs a middleware that enables the integration of this device into a smart grid based on suitable communication protocols. This middleware performs tasks such as the translation of messages between the power substation control centre (PSCC) and electrical equipment in the smart grid. Moreover, the infrastructure satisfies certain requirements for communication between the electrical equipment and the PSCC, such as enhanced security, short response time, and automatic configuration. The paper’s contributions include a solution that enables electrical companies to integrate their legacy equipment into smart-grid networks relying on any of the above mentioned communication protocols. This integration will reduce the costs related to the modernisation of power substations.

“…In [22], the author presented a communication network infrastructure to allow the integration of legacy electrical equipment into smart grids using wireless sensor networks. The same author, in [36], proposed a middleware to monitor electrical parameters in wireless sensor networks (WSNs), enabling smart grid convergence through the retrofit of legacy meters. Similarly, the authors of [23] developed devices that communicate in a multi-protocol network in order to monitor the electrical parameters of transformers, enabling the implementation of a smart grid.…”

A Novel Strategy for Smart Building Convergence Based on the SmartLVGrid Metamodel

Smart buildings provide opportunities for technological transformations in building environments to improve resource management, comfort, and efficiency of the systems present in these facilities. For this, Internet of Things (IoT) solutions contribute, with monitoring and remote control features, to automate these environments. However, these solutions can promote the disposal or replacement of outdated but still-needed legacy systems. Thus, a reference model that uses retrofit techniques to update pre-existing systems would be an alternative to enable smart building convergence. The lack of models that advocate this type of strategy provides an opportunity for the emergence of methods capable of filling this gap. Thus, this work presents a strategy for implementing monitoring, control, and communication resources to achieve smart building convergence in legacy building systems. This strategy consists of the use of retrofit techniques based on the adaptation of the SmartLVGrid metamodel. To validate this proposal, we developed hardware platforms and, respectively, their firmware to implement the premises established in a legacy building lighting circuit. The results obtained present a new possibility of implementing smart buildings from the retrofit of legacy infrastructures, as the pre-existing building lighting circuit obtained new functionalities and was preserved as much as possible.

“…e hash algorithm is currently a widely used load balancing algorithm in the field of load balancing. e main purpose is to ensure that the same request is sent to the same service node each time to achieve cache hits and cross-domain problems [21]. e first hash algorithm is to send the user request to a specific server by performing a hash operation on the user's IP and then modulo the number of servers, which can be expressed as formula (1) as follows:…”

With the rapid development of engineering information technologies such as building Information Model (BIM), geographic information system (GIS), Internet of Things, big data, and cloud computing, and the intelligent management of infrastructure will become an inevitable development trend. Microservice architecture, because of the service component and other related characteristics, using this architecture can build a high availability and low coupling application system, which effectively improves the service quality of the system, and therefore the microservice architecture has gradually become the flow software development architecture. Based on the research of infrastructure digitization and integration of construction and maintenance, this paper proposes the concept of infrastructure intelligent service system (is3) from the perspective of information flow, so as to realize the intelligent management of infrastructure. This paper is based on the system requirements analysis. The intelligent service system of infrastructure with microservice architecture is designed, and its performance is tested through experiment. The test results show that in the brain high development test, the designed service reached no error, and the average response day was stable below 27 ms; in the continuous high concurrent test, the average response time of the designed service side remained within 100 ms when the concurrency is 12000, and no request occurred during the test.
