Analysis of solution of a fire signaling system for a choice railway building

Abstract

The paper presents an analysis of the technical solution of the fire alarm system for the selected railway facility. The task of fire alarm systems (FAS s) and fixed fire extinguishers (FFEs), used in transport facilities, is to detect the fire dangers present in the transport process − both for stationary and mobile objects. These systems are increasingly used in the transport process, where they ensure the safety of people (e.g. airports, railway stations, ports, etc.), transported goods at fixed facilities (e.g. logistic bases, land and sea transshipment terminals, etc.) and transported goods in mobile objects (rail, road, and sea transport). Due to the functions performed in the transport process, they must have a proper functional and reliability structure to ensure safety in the transport process. Keywords: exploitation, complex technical object, handling.

Selected issues of the reliability and operational assessment of a fire alarm system

“…The article analyses the operational process of selected FAS, which are operated within a vast transport area. the occurring operational phenomena in the form of developed research models [10,11]. Fire alarm systems are ones of the most important electronic safety systems (frequently installed at facilities due to the applicable statutory and legal requirements), which are operated within vast transport areas.…”

“…The scope of interest of the theory of safety and risk includes the results of damage and errors, which lead to the states of safety unreliability and hazard of the systems. The issue of correct clarification, which of the FAS states can be deemed acceptable or unacceptable from the perspective of safety or the initial fire scenario developed for a transport facility is very significant in this case [10,11,12,16,19].…”

“…surveillance) to prohibited (e.g. failure of a module or control unit -safety hazard state) states [6,10,11,16,19].…”

“…The quality of information [13,14,15,16,20] received by the systems from detectors [10,11], installed over a vast transport area with a distorted electromagnetic environment (high levels of interfering signals) is also important. Certain research papers propose the application of fuzzy logic [22] or artificial neural networks [6,13,14,15,16,23,24], which are already used in detectors for developing alarm signals [10,11]. The functionality of electronic transport systems is also significantly impacted by environmental conditions, temperature, humidity, vibrations and oscillations [3], as well as electromagnetic interference [1,7,18,20,21] but they are not included in this article.…”
