Description

Technical Field

[0002] With the continuous advancement of urbanization, the height of buildings is increasing, and fire safety issues are receiving more and more attention. When a fire occurs, the accumulation of smoke will not only lead to a decrease in visibility and threaten the safety of personnel evacuation, but also the toxic substances in the smoke will pose a great threat to personnel life safety. Therefore, the smoke exhaust system occupies an important position in the design of building fire protection. In recent years, with the rapid development of Internet of Things technology, its application in the field of fire protection has received increasing attention. The Internet of Things technology can be used to manage and adjust the smoke exhaust system more accurately. Therefore, an automatic smoke exhaust device for fire protection engineering based on the Internet of Things is proposed.

[0003] When the existing IoT smoke exhaust fans need to speed up the amount of smoke discharged, most of them directly increase the power of the motor to make the blades rotate faster, thereby speeding up the smoke flow rate and discharging a larger amount of smoke. However, when the motor rotates at a high speed, it consumes more energy and increases the heat of the motor itself. Combined with the heat contained in the smoke, the heat of the motor may not be effectively dissipated, resulting in overheating and motor failure. Therefore, technical improvements are urgently needed. Utility Model Content
