Měření veličin v bezdrátové senzorové síti ZigBee

Abstract

This thesis deals with the management and monitoring of ZigBee networks and data transmission from the sensor network using ZigBee modules produced by Telegesis company. Specifically ETRX3 modules. The aim was to introduce and describe the wireless standard IEEE 802.15.4, to build sensor networks and devising a development kit that measures and transmits the selected parameters using ZigBee technology across the network into evaluation device. They were implemented circuits for measuring various parameters, both analogue and digital. Created a development kit, which is controlled by a microprocessor and transmits data using a ZigBee network. In the next step was created another application in Promotic SCADA system, which communicates with a wireless model via serial link. Thesis also includes a description of programming tools and software for monitoring ZigBee networks. There is described a development kit Telegesis ETRX3 and its control by AT commands. There are all measured parameters, development kit and basic features of the SCADA system Promotic as well.
