This paper addresses the problem of multiple temperature probes calibration and recalibration for use in demanding medical application. The architecture of the overall calibration system is introduced and the mechanism of calibration data transfer with RFID tag is indicated. A high performance temperature regulation is crucial for the success of the proposed calibration setup. Since the implementation...
Monitoring of the operation, validation and testing of different working regimes of solar power systems is important in establishing some optimal operation strategies based on available renewable resources and load demands. When integrating multiple renewables (photovoltaic, geothermal, biogas) into a microgrid, the usage of devices from different vendors on the same communication network is still...
This paper presents an Internet based SCADA platform for monitoring the structures of a hydropower plant. The remote monitoring system communicates through TCP/IP sockets with the embedded gateway module interfacing the sensor network, facilitating configuration of the sensors, acquisition and archiving of the measurements, visualization of the data in real-time or of the archived data, as well as...
The paper presents an original approach for the cytostatic solution temperature modeling and control. In order to determine a mathematical model with high level of validity for the heating process, an original experimental identification procedure is applied, based on fractional-order operators. The main advantages of the resulted model are highlighted in the paper in a comparative manner with some...
The paper presents a solution for the 13C isotope concentration control inside and at the output of a separation column, solution based on the Internal Model Control strategy. The 13C isotope results from a chemical exchange process carbon dioxide - carbamate, which is a distributed parameter process. In order to model the mentioned process, an original form of the approximating analytical solution...
Nowadays cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy (HIPEC) represents a standard treatment for Peritoneal Carcinomatosis, a final stage of abdominal cancer. HIPEC requires the use of an equipment that delivers the cytostatic solution inside the peritoneal cavity at high temperature of 41°C–43°C. In this paper the authors present a temperature control structure for...
Peritoneal Carcinomatosis (PC) is an abdominal cancer for which cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy (HIPEC) proved to be a promising treatment. HIPEC requires the intraperitoneal spread of cytostatic solution at high temperatures (41–43°C) accomplished within 60–120 minutes, during surgical interventions. This paper presents the heating system's identification,...
Domestic hot water and HVAC energy demand count more than a half from the total residential buildings energy consumption. Two typical principles for hot tap water preparation using a flat station were analyzed: heat exchanger and storage tank. With a storage tank, a boiler consumes 21% less natural gas compared to instantaneous preparation of DHW in a heat exchanger, under moderate simultaneous demand...
This paper presents the architecture of a low cost embedded platform for Web-based monitoring and control of a smart home. The platform consists of a distributed sensing and control network, devices for access control and a residential gateway with touch-screen display offering an easy to use interface to the user as well as providing remote, Web based access. The key issues related to the design...
The paper addresses the sensing and control strategies for dual axis tracking solar concentrators appropriate for solar power systems used for cooling and heating. The constructive structures are introduced together with the remote monitoring architectures appropriate for characterizing the operation of such solar systems. Fundamental positioning structures and tracking principles are analyzed and...
In this paper, a solution for the control of a chemical absorption process of a gas in liquid phase is proposed. The absorption process is treated as a distributed parameter one, its model being expressed using partial differential equations. The parameters of process model are experimentally determined. Also, the control strategy is based on using a modified PID controller with the form adapted to...
This paper presents the design of a digital temperature controller for cytostatic solution used in hyperthermic intraperitoneal chemotherapy (HIPEC). Cytoreductive surgery and HIPEC technique, i.e. Regional chemotherapy using cytostatic drugs at high temperatures of 42-43°C, represents a treatment technique for cancer patients suffering of peritoneal carcinomatosis. The main challenge is to maintain...
Continuous improvements in microelectronic circuitry make possible the implementation of process diagnostics to a variety of systems in order to increase performances and reliability. The monitoring stage in the area of failure detection and isolation aims to classify and arrange the failure sources. In case of BLDC machines, one of the most important methods for failure detection and diagnosis starts...
A low cost architecture is proposed for remote monitoring and control of a greenhouse field. The components needed for such a system are identified by examining the needs and trends of the environmental control systems as well as looking for the appropriate technologies that would offer a low cost. The key features of the proposed platform are remote operation, flexibility, ease of deployment, scalability...
A low cost hardware platform consisting of a measurement system, a communication system and a data processing system is presented. Wired and wireless sensors are developed for supporting motor current signature analysis (MCSA), vibration signature analysis (VSA) and operational temperature monitoring. A “plug and play” software application is implemented for allowing remote computers to share this...
