Description

A special track with spiral-like shape is mounted on the ceiling. Flame sensors (approx. $0,3 each) are installed all over its length with some intervals, so that they cover the ceiling with some density and are able to sense flame emerging at any point on the floor. Whenever a fire starts flame sensor above it sends signals to the computing unit. The CU knows at what track length this sensor is positioned and sends the closest cart to this position. Cart transports a load with an extinguishing agent near the sensor, stops, and drops (or activates) fire extinguisher. The load can be a fire extinguisher ball, a pressurized tank with some chemical or anything else customer chooses. Some additional info: - track is made of standard elements: straight tracks and curved tracks with different radiuses so that one set of elements can be used to cover the ceiling of any room; - distance between adjacent track lines, density of sensors, number of carts are all variable and can be adjusted to meet customer needs; - sensors and carts can communicate with CU using CAN network; - material and cross-section size of a track depends on the weight of cart load; - the system is able to calculate the severity of fire and drop or activate any available number of fire extinguishers on the fire; - track, carts, sensors, CU are made of cheap but reliable components; - carts can even carry water sprinklers that are fed via flexible hoses. In this case cart movement is limited and there would be several number of carts that are responsible for some part of the room; - a cart can move to the correct position using two ways: it can count distance traveled from its initial position using its stepper motor; and ir flame sensor can detect the cart moving underneath it; - the only moving components of system - stepper motors are very reliable. Thus the system does not need regular maintenance; - the system can automatically check its readiness by moving carts and reading sensor data over fixed time intervals;
