In safety-critical systems, many-processor Systems-on-Chip are being increasingly employed. An example is an imminent collision detection System-on-Chip for cars. Such a system requires zero downtime and a very high reliability despite aging issues under harsh environmental conditions. By monitoring the health status of processor cores and other IPs, and taking appropriate counteractions if required,...
This paper describes the proposed system, which is able to monitor, record and give indicator about air quality information especially the CO values in the environment. The system is designed to work real time using web-based and android applications. A portable gas detector was developed using micro controller. In order to detect the CO value, TGS2600 is used; here an additional function is added...
The IEEE 1687 (IJTAG) is a newly IEEE approved standard to access embedded instruments. The usage of these embedded instruments (health monitors) is increasing in order to perform different online measurements for testing purposes as dependability is becoming a key concern in today's electronics. Aging and intermittent resistive faults (IRF) are two threats to a highly dependable system, and temperature...
Reliable sensing is a crucial factor for assessing the structural health conditions of civil infrastructure such as sewerage networks, which are susceptible to hydrogen sulfide induced concrete corrosion. In this context, this paper reports the work on the development and characterization of an instrumentation system using an infrared radiometer for monitoring surface temperature variations of the...
This is an experimental study for acquisition, measurement, processing and display of human health parameters like ECG, Body temperature as well as Saline status. Primarily ECG signal is detected using surface electrodes. As the signal is very feeble in amplitude so an instrumentation amplifier is designed to amplify the acquired ECG signal. Second order Butterworth filter is used to remove the noise...
Temperature measurement of semiconductor components is essential, in particular to evaluate performances and to propose health monitoring of power modules. ThermoSensitive Electrical Parameters (TSEPs) are widely used to estimate a representative temperature of these components, mainly in non-operating conditions, different from the real environment of the latter (offline measurements). Nevertheless,...
Most scientific studies of technologies such as anaerobic co-digestion have focused on raw materials, construction, instrumentation, control and monitoring on-line reactors; under investigation by developed countries which conduct research with elements from developing countries it have been very little studied. In this paper an analysis of the instrumentation, signal acquisition, processing and possible...
For the purpose of environmental impact assessment (EIA) at deep-sea hydrothermal environments towards development and utilization of seafloor massive sulfide (SMS) deposits, we have been developing a cost effective cabled underwater observatory. To realize a flexible and expandable system configuration, the observatory has a simple star-type network and power supply topology by employing an Ethernet...
A greenhouse is a structure generally made of glass, designed to provide protection and controlled environment to raise plants indoors. In order to achieve high quality and quantity of produce, proper management and data collection of the greenhouse environment is required. Manual practice of plant monitoring is laborious and time consuming. The proposed greenhouse system is an application which demonstrates...
Global irradiance sensors supply essential information in the business of planning and operating PV Systems. Errors and uncertainty in irradiance measurements propagate to uncertainty about performance and profitability. PV Performance Labs initiated the PVSENSOR project in 2014 to more fully characterize commercial irradiance sensors, with the objective of reducing such uncertainties. In the first...
Gas chromatography for biogas concentration measurement is too expensive for people who made biogas independently. An instrument with cheaper TGS2611 sensor can be made to monitor biogas concentration. The instrument requires initialization for 60 seconds. TGS2611 sensor output voltage has proportionally changed to the temperature change. Two gas sensors used in the research have 12.125 mV/°C and...
A number of naturally occurring events, such as earthquakes, hurricanes, tornados and floods are capable of causing deaths, injuries and property damages. Hazards associated with earthquakes are commonly referred to as seismic hazards [1]. Almost all earthquakes are preceded by physical processes commonly known as earthquake precursors [1]. Earthquake prediction is feasible by measurement and analysis...
This paper presents the implementation of Virtual Instrumentation (VI) based system used for remote monitoring of selected environmental parameters: humidity, temperature, light intensity and methane. The educational benefits (learning outcomes) of this application are the following: design and implementation of the monitoring circuitry, programming for both LabVIEW and Arduino, understanding VI concepts...
This paper represents a series of online monitoring data from a 500kV bushing on a converter station's transformer. An online monitoring system with a novel tgd measuring method has been successfully used for bushing tgd supervision. Long term data acquisition is evaluated for the insulation integrity of the bushing. It shows that bushing tgδ depends on its temperature/voltage intersect influence...
Analog and mixed-signal IPs are increasingly required to use digital fabrication technologies and are deeply embedded into system-on-chips (SoC). These developments append more requirements and challenges on analog testing methodologies. Traditional analog testing methods suffer from less accessibility and control with regard to these embedded analog circuits in SoCs. As an alternative, an embedded...
Temperature and humidity monitoring is very important in many fields. In this paper, A temperature and humidity monitoring system is constructed. A set of software by LabVIEW language is compiled. The program is operated in a circular manner and automatically. It can display real-time data curve of nodes and record it. When the data exceeds the limit, the alarm indicating lamp will be bright. Temperature...
Messor, a simple but efficient towed vehicle have been built to obtain high-resolution data on the physical environment, phytoplankton, zooplankton, nekton and fish through a variety of sensors allowing multiple data acquisition with a near identical resolution in time and space. A multitude of towing tests have been undertaken to obtain a thorough understanding of vehicle behavior and work potential...
Un-ionized ammonia (UIA) in freshwater is a primary source of toxins that kill freshwater fish. Concentrations as low as 0.03 mg/L can harm fish and concentrations of more than 2.00 mg/L can kill them. The availability of water quality monitoring systems that can directly measure UIA without any chemical treatment on samples is limited. This paper designs a new system by using a programmable system...
In this paper, the procedure of determination, analysis and rectification of repeatable trips causes of off-gas compressors located in condensate stabilization unit of South Pars Gas Complex 2nd refinery, that have instrumentation and control system sources, are presented. Besides decreasing of production rate and increasing acid gas flaring, each trip results serious and inevitable damages on environment,...
