Description

Technical Field

[0001] This application relates to the field of fire extinguisher technology, and in particular to a fire-fighting auxiliary device and its control system. Background Technology

[0002] The electric bicycle sheds pose a high fire risk due to the large number of electric bicycles and frequent charging. During charging, aging wiring, short circuits, and battery malfunctions can easily lead to fires. Once a fire breaks out, it will not only damage the electric bicycles themselves but may also endanger the lives and property of nearby parked vehicles and people.

[0003] For safety reasons, fire extinguishing systems are installed in public electric bicycle sheds. Existing fire extinguishing systems consist of fire extinguishers, smoke sensors, and support frames. When a fire occurs in the shed, the smoke sensor triggers the fire extinguisher, and dry powder is sprayed to extinguish the fire and prevent it from spreading. However, existing fire extinguishers in electric bicycle sheds still have certain drawbacks during automatic spraying. Because there are many electric bicycles parked there, and the number of fire extinguishers installed in the shed is limited, existing extinguishers cannot precisely control the direction of the dry powder spray based on the location of the fire, and they cannot guide the spray direction during spraying, resulting in an excessively large spray area. This reduces the extinguishing effect to some extent and also obstructs the visibility of nearby areas.
