Průmyslové sítě WLAN s podporou inteligentní instrumentace

Abstract

A dissertation thesis is focused on an area of wireless technologies. It deals with creation of wireless sensor networks called „smart dust“and also with a possibility of usage in the technologic process control field. The thesis describes used hardware and software facilities for realization of wireless sensor networks with respect to power consumption of wireless modules emphasizing practical verification of algorithms for time and event-driven data collection. An alternative possibility of solar power for the modules and also hardware for programming have been designed and implemented. The thesis solves possibilities of wireless sensor networks based on IEEE 802.15.4 platform, where two types of networks have been designed and practically tested. The first network has a predefined topology and a number of wireless stations whereas the second sensor network is designed as universal. Other chapters of the thesis focus on the field of technologic process control where a task of the control of hot air aggregate has been realised. They also solve possibilities of connection to a superior network (GSM) including its implementation. The application in Control Web 5 environment named Jenie Net. has been created for visualization and control of sensor networks and hot air aggregate. Jenie Net. enables not only remote configuration of wireless modules and data processing but also data presentation to the Intranet/Internet network.
