Innovative methods for device noise control

Noise is currently one of the most significant hazards to humans in the workplace, making it difficult to communicate by voice, to hear alarms and warnings, and being the source of many ailments and diseases, especially hearing diseases. Noise at home makes it difficult to rest and causes irritation. The most important sources of noise include equipment, both industrial and domestic. The only common way to reduce noise is to enclose the equipment and isolate in this way. The result is that many casings are extremely heavy, thick, and have insulating materials, but this results in high consumption of raw materials and also makes heat dissipation difficult. In addition, such passive methods are not very effective for low frequencies. Classical active methods of noise reduction, based on the principle of destructive interference of acoustic waves, require the use of a large number of sound sources, as well as measuring equipment, and yet they make it possible to obtain only local zones of quiet, while beyond them the sound is amplified. The research presented in this lecture proposes another, much more effective approach to reducing equipment noise – control of device casing. It has been developed in three ways. The first, is passive control, in which by attaching appropriately optimized point masses and ribs to the casing walls, it is possible to fully shape the frequency response of the structure and thus provide high isolation for noise dominant frequencies. An extension of this concept is the use of composite materials with variable properties along their cross section. In the semi-active approach, new actuators are proposed which, attached to the walls of the casing, can change their properties under the influence of the applied control and thus increase the acoustic isolation. In the active approach, exciters or piezoelectric elements are used to control the vibrations of the casing in such a way as to absorb the noise they transmit. The result of each of these approaches is a significant reduction of acoustic emission, and most importantly, it is global in space.

Novel higher order signal processing for vibration condition monitoring

The classical higher order signal processing, that are employed for condition monitoring, will be discussed. Important future directions of higher order signal processing for condition monitoring will be presented for application in transient conditions:

  • new type of non-stationary adaptive spectral transforms
  • new type of non-stationary non-adaptive spectral transforms
  • new type of non-adaptive and adaptive frequency response functions

Validation of these novel techniques by simulation and experiments in laboratory and field conditions will also be presented.

It is shown. that the proposed transforms deliver an essential improvement in effectiveness of vibro-acoustical condition monitoring, comparing to the traditional transforms.

Smart Sensor and IoT for Smart Grid-and-Smart City Applications

In this talk, I would like to emphasize the greater and increasing role of IoT enabled smart sensors in our daily life; an effort to make our existing electricity grid smarter or establishing all together a new Smart Grid, and thereby, making our city life even smarter, popularly recognized as Smart Cities. First, I’ll discuss a new age designed smart gas density sensor and humidity sensors, primarily fabricated for IEC 61850 compliant sub-stations. While; secondly, I shall focus on a new age device known as “Smart Plugs” which is soon going to be an essential component of a Smart Home or a Smart Building.

  • Smart Sensors for the optimal operations of gas insulated switchgears: A direct measurement of humidity inside the Sulphur hexafluoride (SF6) – gas insulated switchgear (GIS), and early detection of leakages of gas from GIS vessels is always challenging. In this regard, fabrication of low-cost, high linear response and high precision sensors are always exciting. SF6 over air as a medium is preferred in GIS because of its improved specific heat and arc-quenching capabilities in the closed environment. SF6 is an inert gas, however, its leakage causes 22,800 times more impact on the environment over greenhouse gases emissions. Typically pressure inside the vessel is maintained at 1.2 Bar and above in GIS. Here, I’ll throw some light on the investigation needed for the availability or design of a humidity sensor that can detect the minimal concentration of humidity, close to 0-2%-RH / 0- 491 ppm-v scale with high sensitivity. Further, detection of gas-leakage inside the SF6-GIS environment engenders precarious damage to the live conductors and some electrical equipment. Especially, measuring equipment and protection mechanisms beneath the vessel can critically affect the time of switching where gas leakage is encountered. These actions are to be closely observed by advanced automation systems as per IEC 61850 and IEEE 1686 protocols. Thus, it is indispensable to place a high precision Gas Density Sensor (GDS) that can measure the leakage of SF6 Gas inside the vessel at PPM/Trace-level with leakages less than 0.5% per annum rate. The recent findings shows that ultrasonic sensor is one of the most suitable options to fabricate a cost-effective, high performance gas density sensor.
  • Smart Plugs to enable a smarter home: In the current energy ecosystem, the need for a Hybrid Appliance Load Monitoring System (HALMS) to establish a smarter grid and energy infrastructure is undeniable. The increasing popularity of the Internet of Things (IoT) has suddenly pushed the demand for smart and connected devices. The smart plugs are a handy solution to make the so-called ‘dumb’ devices smart. The strategy of smart plugs to enhance the energy management experience in connected spaces is presented. We have patented a design of a novel Smart Plug which can remotely control the speed of high power-high current consuming electronic domestic appliances using low-cost communication protocol. These plugs provide you an age to not only monitor your home appliances remotely using Internet of Things (IoT) but also you have an option to control certain operations of dedicated appliances at your home or the power supply network of the house or building.

Overall, both the interconnected segments are pushing towards design and fabrication of “IoT Enabled Smart Sensors” over a single substrate, and is one of the emerging R&D activities in the domain areas.
