IoT applications utilizing excess heat in electrical lighting fixtures

The development of IoT instrumentation will always be strongly influenced by the properties of the power supply system. A large number of IoT nodes creates a danger of extra expenditures when changing the battery. For this reason, the development of supply nodes tends to prefer systems capable of battery-less operation, obtaining energy from other sources. This article deals with an alternative method of electrical energy acquisition form the excessive heat appearing in LED lighting fixtures utilizing large-area LED chips. A Peltier cell was used for the conversion of heat energy to electrical energy, connected as thermo-electric generator into the thermal chain

Honeypots and honeynets: issues of privacy

Honeypots and honeynets are popular tools in the area of network security and network forensics. The deployment and usage of these tools are influenced by a number of technical and legal issues, which need to be carefully considered. In this paper, we outline the privacy issues of honeypots and honeynets with respect to their technical aspects. The paper discusses the legal framework of privacy and legal grounds to data processing. We also discuss the IP address, because by EU law, it is considered personal data. The analysis of legal issues is based on EU law and is supported by discussions on privacy and related issues

Batch process in connection with industry 4.0

This project deals with the creation of autonomous liquid storage cell with a cooling system. The cell is part of a larger project called the Self-Acting Barman. Project Barman serves to demonstrate the principles of Industry 4.0 and is gradually made up of student works. The aim of the project is to create a cell that can dispense the required amount of fluid. The cell is cooled by an external cooling cell. The entire liquid batch process is controlled by a PLC located at the cell interface. By default, the process would be controlled by a superior batch system that complies with the ISA-S88 standard. The paper aims to clarify the fusion of the S88 standard with the new 4.0 approach

High power solid state retrofit lamp thermal characterization and modeling

Thermal and thermo-mechanical modeling and characterization of solid state lightening (SSL) retrofit LED Lamp are presented in this paper. Paramount Importance is to design SSL lamps for reliability, in which thermal and thermo-mechanical aspects are key points. The main goal is to get a precise 3D thermal lamp model for further thermal optimization. Simulations are performed with ANSYS and Covent or Ware software tools to compare different simulation approaches. Modeled thermal distribution has been validated with thermal measurement on a commercial 8W LED lamp. Materials parametric study has been carried out to discover problematic parts for heat transfer from power LEDs to ambient and future solutions are proposed. The objectives are to predict the thermal management by modeling of LED Lamp, get more understanding in the effect of lamp shape and used materials in order to design more effective LED lamps and predict light quality, life time and reliability

IoT monitoring system for farmers

Článek se zabývá návrhem a testováním monitorovacího systému pro potřeby farmářů. Systém sestává z integrovaných autonomních BLE beacon, které jsou umístěny na sledovaných objektech (v našem modelovém případě se jedná o skot). Tyto beacony vysílají v určených periodách svoje identifikační údaje společně sdalšími doplňkovými informacemi, které následně slouží pro provedení přesného zaměření sledovaného objektu ve sledovaném prostoru (louka, pastva, ohradník)..the Technology Agency of the Czech Republic under the DELTA support programme for applied research, experimental development and innovation No. TF06000066and partially by the EU projects (Energy for Smart Objects (EnSO), No. 692482-2, Wide band gap Innovative SiC for Advanced Power (WInSiC4AP), No. 737483), project of Technology Agency of the Czech Republic No. TH03010205 MEMS sensors with optical scanning (MEMS-ESO) and by Smart Access Control for Smart Buildings (SACON), No. 12708.This paper discusses the concept, design and testing monitoring system for the needs of farmers.The system consists of integrated autonomous BLE beacons, which are located on monitored objects (in our model case, cattle). These beacons transmit their identification data in specified periods together with other additional information, which is then used to perform the precise targeting of the monitored object in the monitored area (meadow, grazing, fence)

Energy consumption optimization for thermal energy harvester applications

This paper demonstrates the concept of node consumption reduction for IoT applications. The main emphasis is placed on the autonomy of the whole device, which must be independent of external power supply. That is why energy harvesting based on temperature principle is used for power supply. One of the parameters monitored is the service uptime. The concept of intelligent control of the individual parts of the equipment leads to significant energy savings. This control requires the use of low power components, but only their appropriate connection and mutual monitoring of their operating modes leads to the desired savings. This algorithm can be adapted to the needs of IoT nodes focused on real-time performance applications or the process tracking slow low power applications. This concept will ultimately be adapted to a wireless node for monitoring position and temperature for use in medical applications to monitor the patient's position on the bed or position while moving

IoT applications utilizing excess heat in electrical lighting fixtures

Vývoj IoT zařízení bude vždy silně ovlivněn možnostmi napájení systému. Značný počet uzlů IoT (node) vytváří nebezpečí dodatečných nákladů při výměně baterii. Z tohoto důvodu se vývoj napájení uzlů zaměřuje na zařízení, která mohou pracovat bez baterie a energii získávají z jiných zdrojů. Tento článek se zaměřuje na alternativní získání elektrické energie z odpadního tepla vznikajícího při provozu LED svítidel obsahující velkoplošné LED čipy.
