Defrosting of coal wagons in Slovak powerplant

Introduction

The main goal of Austyn International was to design and deliver modern and economical system for brown coal wagons thawing in Slovak power plants – ENO Nováky. The system must use existing facilities, ensure continual and effective defrosting, minimize operating costs, reduce heat losses, increase reliability and accuracy of control.

Solution

The thawing system consists of 450 infrared heaters with 3.6 kW outpout and 108 heaters with 1.2 kW output, automatic RS AGS system, which controls thawing based on input data (on wagons and outside temperature). Data are transferred wirelessly through the IQRF mesh network.

Conclusion

Thanks to this solution (infrared heaters with 1.8 MW input power controlled by the AGS system) there is no threatened electricity production and heating for the town of Prievidza, and the risk of failure of fuel supply to boilers is reduced to a minimum. Thanks to a reliable and secure IQRF network it is possible to obtain data from a large number of sensors at once and control the infrared heaters. IQRF wireless mesh network can transfer data even under such harsh environment.

IQRF IDE Command is a new software for controlling IQRF transceivers

IQRF IDE Command is a TR programmer (uploader) running from the command line.

This new software tool is intended for experienced developers, to provide them with faster and more effective design process, or for unskilled operators, to speed up and secure the manufacturing. IQRF Simply run a batch file by a single stroke, avoiding an operator’s failure.

IQRF IDE Command is supported by transceivers (TR-5xB, TR-5xD, TR-7xD or higher), IQRF USB development kits (CK-USB-04(A), …), IQRF gateways with USB interface (GW-USB/ETH/GSM/WIFI). IQRF IDE Command works under Windows 10, Windows 8.x, Windows 7 and Vista (not tested for Windows XP).

To prevent any issues always use the latest IDE Command version from www.iqrf.org. The upgrade is very simple – just unzip the .ZIP package.

Air quality monitoring in a Prague school

Introduction

Because of the assumption that there is a bad air in schools, and therefore students have concentration problems, Protronix and his partners (O2 IT Services, IQRF Alliance, MICRORISC, Camea, …) decided to make a long-term 4-months measurement. The CO2, temperature and relative humidity values were monitored. They were continuously analyzed and finally followed by recommendations for ventilation.

Solution

This solution consists of 10 combined sensors of CO2, temperature and relative humidity, and an IQRF wireless mesh network for data transfer, a gateway enabling data transfer from the IQRF network to TCP/IP network, a data storage and a web application with visualization of measured data.

Conclusion

As a result, it was found that minimum recommended values of relative air humidity had not been reached for most of the schooltime and maximum allowed CO2 values had been exceeded for almost half of the time. These variables and their values are directly linked to the concentration and health of students.

The IQRF network is easy to install, so installation of all sensors and their subsequent removal took place within a very short time without disturbing the teaching. The entire large school for 600 students was covered by a network with 10 hops, although the IQRF network has more than 240 hops. Extention of additional sensors would be easy.

DAVOS MATRIX by CTI Software brings AI to IoT

Last year DAVOS MATRIX started its presence within IoT as an intelligent service that can call you on your mobile phone as soon as the emergency situation detected by wireless sensors develops. Now it has made a big step forward integrating the IQRF wireless technology.

Thanks to the presence of the IQRF wireless technology, the system has completely new functionality. Our intelligent lighting control allows remote management of public lighting and industrial luminaires, including monitoring of unusual operating conditions. It is designed for all types of luminaires.

In addition to automatic behavior of the lighting system, it is possible to change the settings of individual luminaires manually by an authorized user. If the luminaire provides the option of adjusting various lighting intensities (dimming), this parameter can be changed as well.

The control unit (including IQRF gateway) communicates with all the luminaires wirelessly via the IQRF meshnetwork. At a short point in time, it sends all the IQRF receiving modules in the luminaires requests to change settings or query the current status. The IQRF receiving modules send back to the control unit responses to its requests and, moreover, transmit all memorized error states since the last communication.

IQRF receiving module can be placed directly inside the luminaire’s construction if the dimensions allow it, or attached to a plastic pocket above the luminaire (via the NEMAconnector). The receiving module checks the connected luminaire for its functioning. At defined intervals, the drawn current is measured. It can then evaluate deterioration or degradation of the luminaire in order to prevent an early failure.

Next to this project we plan to use the IQRF technology also in our air quality sensors as it is the best solution for local stationary deployments. Together with our telephonyalarmnotification service DAVOS MATRIX can bring an excellent added value for many IQRF based devices and solutions.

DCTRs for price of TR

Since August 1st, 2017, all IQRF transceivers support DPA functionality (easy integration, compatibility, interoperability) at no extra costs.

Using DCTRs (Data Controlled Transceivers) extremely simplifies and speeds up implementation of wireless connectivity and enables interoperability of devices from different vendors. DPA framework provides advanced tools and services such as OTA upgrades, mesh networking, remote service and much more.
