Abstract
U okviru diplomskog rada razvijen je sustav nadzora kvalitete zraka u zatvorenim prostorima. Sustav je razvijen koristeći koncept bežične senzorske mreže. Sustav prikuplja podatke s terena čiji su izvori senzorski čvorovi, a ponori distribuirane instance korisničke aplikacije. Senzorska mreže u konačnici prikuplja podatke o: • zadimljenosti prostorije, • količini lebdećih čestica u zraku, • grubu detekciju količine štetnog plina u prostoriji, • mjerenje temperature i • iznos relativne vlažnosti zraka. Senzorski čvorovi raspoređeni su u promatranom objektu, a prikupljeni podaci su proslijeđeni centralnom poslužitelju. Centralni poslužitelj je realiziran Internet aplikacijom. U okviru rada obrađene su osnove kakvoće zraka, zatim je opisan osnovni princip definiranja sustava (bežične senzorske mreže) s predloškom za izvedbu zadanog sustava. Obrađene su potrebne jedinice, među kojima su senzori za mjerenje potrebnih fizikalnih veličina, bežični komunikacijski moduli i mikroupravljački uređaji. Opisana je priprema okoline i konfiguracije, primjerice na usmjerniku za definiranu funkcionalnost prenošenja podataka iz senzorske mreže do korisničke aplikacije. Opisana je izrada korisničke aplikacije čime je dovršena izrada funkcionalnosti sustava. U konačnici izvedena su mjerenja prijema paketa kako bi se doznala ograničenja sustava, vezana uz domet i strategiju postavljanja komunikacijskih čvorova. U zaključku su predložena moguća unapređenja postojećeg rješenja ili mogućnosti prenamjene sustava.
Abstract (english)
This thesis goes through a study and a practical development of a system of indoor air quality management. Indoor air quality management system is been developed with the wireless sensor network concept in its focus. This system is capable of collecting data from a distributed network of sensor nodes. Visualization of data is made by a service of user applications which are distributed to network clients. Sensor network collects data about: • amount of smoke in an object, • amount of particle matter in the air of an object, • approximation on the amount of harmful gas or gases in the object, • current temperature, • and amount of relative humidity. Sensor nodes are deployed to a selected complex, collected data is been forwarded to a central server. Server is implemented as a web application. Thesis elaborates the basic principle of defining the system (of wireless sensor networks) with its model for the performance measurement. Study on all necessary components is been presented, including sensors, wireless modules and microcontrollers. Basic settings and preparation of the environment is been defined, e.g. for the functionality of relaying data from sensor network to the user application. Afterwards, one can find notations on a development of the user application which completes the functionality of the proposed system. Finally, measurement are been presented on the packet reception rate, which can indicate on the limitations of the system doe to the propagation of packets in indoor environment. Measurement can be used as a indication for strategies on setting up network configuration and node distribution. In the conclusion there are proposed improvements for the selected solution or possibilities of functionality conversion.
