This paper deals with fire detection simulation by fiber laser in the road tunnel. Influence of the pressure difference for various vehicle type fire scenarios on the air speed in the tunnel is considered by evaluation of the average temperature in the fire section. Final simulation experiment is realized in programmable logic controller based tunnel simulator of road tunnels technological equipment.
The paper concerns an application of genetic-fuzzy systems to automatic tuning of a fuzzy meta-model for evacuation speed estimation. The paper first covers some basic facts concerning evacuation in road tunnels and its simulation. It then proceeds to discuss the basics of genetic-fuzzy systems and proposes an evolutionary approach for automatic tuning of said meta-model. The approach is verified...
This paper deals with object oriented software implementation of the algorithms for transformation of the continuous-time linear systems to the discrete-time systems. These algorithms are used for displaying the basic discrete-time systems characteristics: step response, impulse response and frequency response in PLC based tunnel simulator. State-space system representation and basic interconnection...
This paper deals with obtaining the meteorological data (temperature, wind speed, wind direction, clouds coverage, sun rise, sun set) from the internet weather servers through free weather API functions in XML format. Together with stored operational data (traffic intensity, traffic speed, opacity, CO level…) from the existing tunnel are this data sent into the PLC based tunnel simulator through external...
