20.500.12556/RUL-173993 Primernost sistemov za odkrivanje in javljanje požara na kmetiji diplomsko delo Suitability of fire detection and alarm systems on farm B. Sc. thesis Požari na kmetijskih objektih so velika nevarnost za živali, ljudi in premoženje. Zaradi prisotnosti gorljivih materialov, kot so mrva, nastil, lesena konstrukcija, se požari hitro širijo, zato je pomembno, da jih zgodaj zaznamo. Glavni namen diplomskega dela je bil raziskati različne sisteme za odkrivanje in javljanje požara ter ugotoviti, kakšen sistem bi učinkovito deloval v posameznih kmetijskih objektih, to je hlevih za govedo, prašiče, kokoši in pitovne piščance, konje in drobnico ter skladiščih mrve.S pregledom literature smo raziskali različne vrste javljalnikov, kot so javljalniki dima, toplote in plamena, ter kakšne so njihove prednosti in slabosti. Pri značilnostih kmetijskih objektov smo se osredotočili na dejavnike, kot so temperatura, zračna vlaga, prah, gibanje zraka, način uhlevitve in velikost prostora, ker ti lahko vplivajo na delovanje javljalnikov požara. Z analizo zbranih podatkov smo ugotovili, da zahtevni pogoji v hlevih, predvsem v prostoru, kjer bivajo živali, dovoljujejo optimalno delovanje le nekaterim javljalnikom. Najprimernejši je dimni aspiracijski javljalnik, ker imajo dejavniki v večini hlevov nanj majhen vpliv. Razmeroma primeren je tudi kombinirani javljalnik, saj se zaradi dveh sočasno delujočih senzorjev v enem javljalniku zmanjša pojavnost lažnih alarmov. Toplotni javljalniki so neprimerni za uporabo, saj požar zaznajo pozno. Plamenski in žarkovni javljalnik ter zaznava preko video slike so primerni za uporabo le v velikih preglednih prostorih. Njihovo delovanje omejuje prašnost v prostoru. V hlevskih prostorih, ki so namenjeni človeški uporabi, npr. pisarna, garderoba itd., sta najprimernejša dimni optični in kombinirani javljalnik. Ob vsaki uporabi sistema za javljanje in odkrivanje požara je običajno nameščen tudi ročni javljalnik. Fires in agricultural buildings pose a significant risk to animals, people, and property. Due to the presence of flammable materials, such as hay, bedding, and wooden structures, fires can spread quickly, making early detection crucial. The main aim of this bachelor’s thesis was to investigate different fire detection and alarm systems and determine which system would work effectively in different types of farm buildings, namely cattle, pigs, hens and broilers, horses and small livestock barns, as well as hay storage facilities. Based on a literature review, we examined different types of detectors, such as smoke, heat, and flame detectors, and evaluated their advantages and disadvantages. In agricultural buildings, we focused on factors such as temperature, humidity, dust, air movement, housing system and the size of the room because they can affect detector performance. Analysis of collected data showed that the demanding conditions in barns, especially in areas where animals are housed, allow for the reliable operation of only certain detectors. The most suitable option is the aspirating smoke detector because most factors in barns have minimal effect on its performance. The multisensor detector is also relatively suitable because the two sensors working simultaneously in one device help to reduce false alarms. Heat detectors are unsuitable because they detect fires too late. Flame, beam detectors, and video-based detection systems are only suitable for large, open spaces where their effectiveness is limited by the dust in the environment. In barn spaces intended for human occupancy, such as offices or changing rooms, optical smoke detectors and multisensor detectors are most suitable. Any fire detection and alarm system should also include a manual call point. kmetijstvo kmetje požarna varnost agriculture farms fire safety true false false V.
