This paper presents the automation of the power distribution system of the Pici Campus of the Federal University of Ceará. The paper aims to present the integration via protocol Open Platform Communications (OPC) of an application program for automatic restoration and a commercial Supervisory Control and Data Acquisition (SCADA). OPC ensures different application programs with proprietary protocols...
RESTCONF is a management protocol, based on REST principles, currently under design at the IETF. In this paper, we present our solution for automating conformance testing of RESTCONF agents. The solution takes as input the set of YANG modules supported by the agent and automatically generates test cases based on the YANG definitions. Test cases are consumed by a test execution environment, which issues...
An efficient supervision system requires not only a highspeed system, but also high reliability (i.e. fault tolerant systems), high flexibility (generic design) and high scalability (distributed design). Industrial applications have revealed these absolute needs that distinguish modern architectures from the known ones. Marrying top-level researches from three distinct domains — automation, distributed...
In the future, production systems will consist of modular and flexible production components, being able to adapt to completely new manufacturing processes. This requirement arises from market turbulences caused by customer demands, i. e. highly customized goods in smaller production batches, or phenomenon like commercial crisis. In order to achieve adaptable production systems, one of the major challenges...
This paper explains the different layers of integration in intelligent building system and analyses characteristics and problems of four existing integration modules. Two new solutions of parallel integration module and OPC componential integration module are presented. The core idea of parallel integration module is that BMS network is divided into management network and monitor network with its...
Buffer overflow vulnerabilities can cause attacks that result in serious consequences. However the techniques of buffer overflow vulnerability detection are limited to manual analysis, binary-patch comparison, fuzzing and so on. They rely on manual analysis, thus cause high overhead. In this paper, we propose a novel method of detection of buffer overflow vulnerabilities, which is based on fuzzing,...
Energy consumption is a major component for industries and distribution licensees. Its effective control is a means of increasing reliability, availability and profitability. In a transmission and distribution system, few of the reasons behind a high technical loss are improper load management, overloading on distribution side, ageing of equipments and inaccurate metering. Further, losses depend on...
