The Model Based Systems Engineering (MBSE) is herein applied to design a physical node for an interconnected system, based upon data exchange. As a test case the concept of smart bearing equipped with sensors to be used to monitor a cold rolling mill is preliminarily developed. The paper focuses on the two activities of inner and outer monitoring of the bearing service. Outer monitoring is aimed at...
In hydraulic piping system, health management has become a challenging task. As operating in harsh environment, damage detection and fault diagnosis are important to hydraulic pipes. In this paper, an intelligent monitoring system is proposed for hydraulic pipes based on multiple sensors. Firstly, it collects and records various parameters of pipes such as vibration, hydraulic pressure, temperature,...
The strategic infrastructure, electrical grid, railroad, water and natural gas delivery grids are nowadays the target of choice for either terrorist or stealing activities. Monitoring the strategic infrastructure in order to prevent failures due to such activities is not an easy task due to the complexity of these systems. In this article it is presented a possible solution for monitoring the 110/400...
The monitoring and identification of suspicious activity is necessary for protection of Critical Infrastructure. The protection is extended to an early warning area beyond the physical security perimeter. The early warning area can cover from kilometer to hundred kilometers. The analysis of soil induced vibration by walking, digging, vehicle, can provide the useful information about human activity...
This paper presents research and development results of a prototype portable system designed for monitoring and recording HPP (Hydroelectric Power Plant) workplace environment data (noise, vibration, pressure, temperature, gas concentration and light level), related to working health conditions observing the requirements from current national and international standards. This has been achieved by...
This paper reviews energy harvesting technologies for structural health monitoring applications. Structural health monitoring (SHM) is the process of damage detection in machinery, aerospace, and civil structures. There is a great deal of interest across a broad section of industries in obtaining technology that can be used to monitor the health of machinery and structures. In particular, the need...
Road vehicle improve the quality of people's life, however harmful vehicle exhaust emissions, such as carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO2), hydrocarbon (HC), and sulphur dioxide (SO2), have become more and more unacceptable and endangers human health. To reduce the pollution from road vehicle engines, the first step is to develop accurate monitoring equipments and technologies...
Because of the wireless remote monitoring system has more and more application, a remote monitoring system based on GPRS and internet is presented. Based on the total design of the system, the hardware and software of the system is designed. The design method is suitable for any remote monitoring and control system if the sensors and conditioning circuits are replaced. So there is certain reference...
A highly effective Structural Health Monitoring, SHM, system for aerospace applications must be, besides highly reliable, a low complexity and low weight solution. This can be achieved with a reduced number of sensors, which normally implies a low resolution mapping of the monitored variables and, consequently, a weakness on the diagnosis and prognosis procedures. To overcome these difficulties, the...
This paper presents a sensor system used to measure the height variations of the overhead contact wire feeding electric traction trains when a pantograph is passing. These measures are used to determine the occurrence of defects in the catenary-pantograph interaction. The non-contact sensor for monitoring catenary-pantograph interaction (NCCPI) system consists of a line-scan camera focused to an infrared...
Wind turbine condition monitoring (CM) is an area of research which has been receiving a large amount of attention in the recent years. This has been influenced mainly by the recent uptake of wind farms being installed around the country. Operational and maintenance expertise in the area of wind turbine CM is therefore seen to be of growing importance but is yet to be well established in the industry...
This paper describes a human health monitoring system by an air pressure sensor and an ultrasonic sensor system. The ultrasonic sensor system can obtain the state of a patient in bed by placing it under a bed frame. That is, we can determine whether or not a patient in the bed. The air pressure sensor system can detect heart beats by placing it to the mattress on the bed. By using two sensors complementary,...
Historically many different signals have been employed in the quest for optimal automatic closed loop mill control. These include mill power, sound, elevator amps, bearing pressure and temperature as a few examples. However, within the last few years, a new technology is emerging that makes all these antiquated techniques obsolete. This new technology is mill control using vibration sensors, analog...
