This paper is presented to introduce a system constituting of a PLC (Programmable Logic Controller) that is connected to the level switches which is monitoring the level of the tank. This system saves the tank from over flowing which increases the safety and efficiency. The levels are considered as an input to the PLC and the pump is controlled by the output of PLC which pumps out the solvent or any...
Attacks targeting software on embedded systems are becoming increasingly prevalent. Remote attestation is a mechanism that allows establishing trust in embedded devices. However, existing attestation schemes are either static and cannot detect control-flow attacks, or require instrumentation of software incurring high performance overheads. To overcome these limitations, we present LO-FAT, the first...
This research focuses on the implementation of a training system, which is used in teaching of remote control existing thematic industrial processes in education for engineering, the most important stages of the implementation of this system are described as the description of the use of the educational system and the results to be obtained in practical applications. Surveys indicate that the training...
The safety of critical structures such as dams, are great concern of authorities around the world. Conventionally, systems based on time series analysis method have been used to detect anomalies in order to ensure the safety in the operation of these structures. This paper proposes a supplementary system able to receive messages and alarms coming from the first assessment performed by the main system...
The project developed a mobile application, web access and virtual instrument to monitor and control through an embedded system, an industrial process for stamping parts, in real time, remotely and field; integrating the benefits of the Internet and networks of cellular mobile telephony. The mobile application implemented the methodology for the development of mobile applications, web access implemented...
Os centros de controle de motores (CCMs) de baixa tensão são numerosos, consumindo grande parte da interação do operador e manutenção de um sistema de distribuição de potência industrial. A ampla interação humana com estes circuitos de baixa tensão (menos de 1 kV) torna um CCM de baixa tensão um local de risco potencial significativo. O grande número de circuitos do CCM de baixa tensão resulta em...
Controlling of liquid level in Nonlinear spherical is a difficult task in industries. It is highly non linear because of its shape. This paper represents a micro controller based Nonlinear tank level monitor and controlling system using LabVIEW(Laboratory Virtual Instrument Engineering Workbench). Differential Pressure Transmitter (DPT) measures the level and it gives the corresponding analog voltage...
In this article the authors examines up-to-date relationship between theory of polymetric measurements and state of art in intelligent robots sensing. The paper contains commentaries about: concepts and axioms of polymetric measurements theory, corresponding monitoring information systems used in different technologies and some prospects for polymetric sensing of intelligent robots. Furthermore they...
Após um longo período de crise, a indústria naval brasileira está passando por um novo processo de expansão. Entretanto, alguns dos problem as críticos que ainda persistem podem vir a impor barreiras à consolidação do setor. O risco do estaleiro apresenta-se como um dos principais problem as da indústria. O controle do progresso físico e financeiro dos empreendimentos é uma medida de fundamental importância...
Absorbance data collected from an online UV absorbance spectrophotometer installed for water quality monitoring at a conventional drinking water treatment plant was used to develop surrogate parameters for treatment process monitoring and optimisation. Surrogate parameters were developed via data analysis of collected online data as well as by targeted selection from previous research knowledge. These...
Service-Oriented Architecture offers a technical foundation for Enterprise Application Integration and business collaboration through service-based business components. With increasing process outsourcing and cloud computing, enterprises need process-level integration and collaboration (process-oriented) to quickly launch new business processes for new customers and products. However, business processes...
With the rapid advancement of Internet technologies, remote access of laboratory equipment and instrument via Internet is fast becoming a reality. This paper presents the implementation of a remote laboratory experiment for process engineering education. Based on configuration software and its extended application, we investigated five essential design issues: requirement specification, system architecture,...
This paper presents the State-of-the-Art and recent trends of SCADA system Architecture, which is usually three-layer SCADA system architecture depending on open system technology rather than a vendor controlled, proprietary technology. A Real-time Industrial process is simulated (boiling system), and a complete three-layer model SCADA system is developed for this process, supervision control layer,...
The quality of an intelligent control system is the ability to control the process with a certain degree of autonomy. These requirements, as an autonomous process controller are ever increasing. Considering the fact that existing algorithm based controllers such as the adaptive PID have their own limitations/are inadequate, the controllers are designed to emulate human mental faculties such as adaptation,...
As the insufficiency of artificial methods for silkworm incubation, a new real-time monitoring system based on pre-evaluation compensation with gain self-adaptive control designed for silkworm incubation is introduced in this paper. The system enables silkworm regularly and automatic transposition for a 360-degree, and has light, temperature, wet-precise control. It also manages the sales process...
The introduction of microprocessor-based plant control occurred shortly before 1980 with simple single-loop controllers. This technology quickly evolved into a DCS with control processor redundancy, high-density input/output systems, and a human machine interface (HMI). Today's tank management plans are faced with intense pressure to improve storage reliability. Thereby, current business goals focus...
A design and key technique about process control system is introduced based on RS-485 bus, and the communication principle and method of software realization are discussed. A suit of on-line monitoring system is made which takes on better stability and anti-jamming ability, upper data transmission velocity and far side transmission distance.
A new monitoring and control system for clinker rotary kiln is proposed in this paper. This system underpinned with a mathematical model of the process consists of five operational layers; three layers for monitoring and two for control system. In this paper, we focus on monitoring system which is made up of instrumentation, mathematical model processing, and visualization layers. The control system...
The purpose of TAFT fault tolerance studies conducted at CNES is to prepare the space community for the significant evolution linked to the usage of COTS components for developing spacecraft supercomputers. CNES has patented the DMT and DT2 fault-tolerant architectures with 'light' features. The development of a DMT/DT2 testbench based on a PowerPC7448 microprocessor from e2v is presented in this...
This paper presents an eye-gaze tracking system based on the image processing. All the computations are performed in software and the system just needs a PC camera attached to the user's computer. We first extract the facial regions form the images using the skin-color model and connected-component analysis. Then the eye regions are detected by employing the rules and area segmentation. After the...
