Overview

STFS - Smart Tunnel Fire Simulator - is a project of the HTL Mössingerstraße in cooperation with the ASFINAG, which should not only shorten the preparation work for exercises in tunnels, but also to provide a wider range of training scenarios.

The problem

The ASFINAG is obliged to carry out regular training sessions with fire brigades in all Austrian motorway tunnels. In particular, fire simulations are very time-consuming and difficult to implement, since in tunnels no open fire may be used. It can therefore neither be determined whether the fire is actually extinguished and if the amount of water supplied to the fire suffice to extinguish it.

The solution

The development of a portable and smart fire simulator in the form of a car allows to carry out a fire excercise without open fire and pyrotechnics. This not only allows a wider range of training scenarios, but also a more realistic implementation, so that firefighters are well prepared for emergencies.

The product

Due to the special and modular design as well as the smart programming, a variety of scenarios can be presented (e.g., engine fires or full fires). The fire simulator has the necessary logic to compare the incoming water volumes with reference values ​​and automatically regulate the brightness of the light sources. With a web app developed by us, the exercise can be evaluated and controlled in real time.

Details

Our project covers various topics. In order to give you a better insight into the individual subareas, we have divided our project into three categories.

Chassis

The body, which is in the shape of a car, is not only lightweight, so that the fire simulator can be quickly positioned, but also waterproof and stable. During an excercise a lot of water at high pressure hits the device. That's why aluminium profiles are used. Because of the special construction and modular design, a variety of scenarios can be simulated (e.g., engine fire or full fire). The individual modules with the LEDs and the sensors can be arranged arbitrarily. As a side panel checker plate is used, leaving free small windows that resemble car windows, through which the fire can be extinguished later.

Electronics

The fire simulator has the necessary logic to compare the incoming water volumes with reference values ​​and automatically regulate the brightness of the light sources. For this an Arduino with a GSM module for the data transmission to the server and a further Arduino for the evaluation of the sensor values ​​are used. In addition, the measured data is stored locally on an SD card to not lose any measured values ​​in the event of a connection loss. All electronics are in an IP65 waterproof control cabinet. The fire is simulated by special LEDs, namely WS2811 LED strips. In this LED strip, three LEDs are each individually controllable, which more color effects are possible and the fire is more realistic. The incoming water quantities are measured with a water flow sensor with a turbine. The brightness of the LEDs is automatically controlled due to the incoming amounts of water to make the fire even more realistic.

Software

With a web app developed by us, the recorded data and thus the extinguishing success can be evaluated either in real time or retroactively via a web interface. The exercise can be controlled live on location or remotely in a control room with a PC or a smartphone. The instructor can instantly change exercise parameters during the exercise and manually stop the exercise. A special feature of the web app is the live control and evaluation. We work with TCP sockets, which make it possible to exchange data between client and server or Arduino and server, without having to establish a new connection with each data packet. In our case this means that new data can be received without reloading the page.

This project will be carried out together with a business partner.

We would like to thank our partners for the active support and cooperation. Without the HTL Mössingerstraße, which provides the infrastructure, and the ASFINAG, which financed the project, the implementation would not have been possible.
