Description

"safe and protect life. and assets." central aspect of this task is to prevent fire and to exstinguish it. one way to prevent, is detecting the fire: a technical variant for that could is by "monitoring of gas". a concrete (low-cost) solution for this application is well known from the automotive industry: in cars are integrated small and modular solutions, which are supplied with embedded software for converting gas measurements into air quality measurements. this happens in terms of a tvoc(total volatile organic compounds)-measurement or equivalent co2-value. because of the applications including automotive systems, consumer devices and industrial equipment, there is a wide range of sensors available: different lifetimes, power consumptions, sensitivities can be bought for a good price. ( sidestep: this idea could be disruptive or frugal, by recycling systems from used cars and to convert these to an indoor, static solution.) * a network of sensors could generate advantages: sensoring at one spot is realize by wearing the sensors on the body. so the (moving) workers are a part of the detection-system. one more benefit could be, if a worker falls or get unconscious because of carbonmonoxide, his/her smartphone could warn the fire brigade. a second system based on an usb-stick which can be used to create a kind of swarm. this system uses every computer in the plant as a fire-detector via an usb-stick. if all sensors are connected, a network could be establish. the sensors could be able to learn, when a situation is escalating. this should lead to a 100% reliability. * future: air quality is a general matter. the ratio of oxygen is relevant for the performance of workers. the same sensors could be integrated in an (installed/existing) air conditioning system. in that case the sensors have a 24/7/365-function: they help to keep workers healthy or on a high performance level. because of detecting co2 or co they can warn if the air in the hangar isn´t fresh anymore. so the swarm of sensors is able to detect a upcoming fire and they help to keep workers healthy.
