Description

Automatic flame-retardant alarm device based on ZigBee wireless sensor network

Technical Field

The utility model relates to a wireless sensor network technical field especially relates to an automatic fire-retardant alarm device based on zigBee wireless sensor network.

Background

Fire safety is an essential item for safety checks, especially in large public places and important warehouses, where most application scenarios are visible or open places. However, in real life, it is often found that in the process of transporting goods, due to the flammable and explosive properties of the goods themselves or the influence of external factors, such as sunlight, temperature and the like, spontaneous combustion of the goods occurs, which causes serious economic loss, and the goods are often found in express delivery vehicles. Because the freight carriage is closed, the condition in the carriage is difficult to discover in time by a driver, the sporadic fire points quickly develop into a big fire under the assistance of wind because the vehicle runs at a high speed, and the driver can not effectively extinguish the open fire when discovering that the carriage is on fire because of the visual blind spots, thereby causing serious economic and property loss. Meanwhile, in the normal driving process, a driver stops and checks the vehicle, personal safety hazards can be brought, and traffic accidents are more easily caused.

The small-sized hand-held fire extinguisher carried by the existing vehicle cannot effectively extinguish the fire due to the limitation of the volume and the delay of finding the fire. If the cargo compartment door is opened by trade, the inrush of a large amount of air further helps to spread the fire rapidly, and the resulting economic loss is difficult to predict. Based on such a real situation, a new technology is needed to deal with the problems like this, so we propose an automatic fire-retardant alarm device based on the ZigBee wireless sensor network to solve the above problems.
