[0002] In modern buildings, fire safety is of vital importance, especially in large commercial buildings, hotels, hospitals, power stations, factories, warehouses, underground garages, subway stations and tunnels. In these environments, once a fire occurs, the rapid spread and accumulation of smoke will greatly threaten the safety of life and property. Therefore, as an important part of the fire safety system, the effectiveness and reliability of the smoke exhaust system are crucial.

[0003] The main function of the smoke exhaust system is to quickly exhaust smoke from the building through the smoke exhaust fan when a fire occurs, so as to reduce the harm of smoke to personnel and ensure the smooth flow of evacuation passages and fire escape passages. In order to achieve this goal, the smoke exhaust fan controller, as the core component of the system, undertakes key tasks such as controlling the start and stop of the fan, monitoring the operating status, and fault alarm.

[0004] Traditional smoke exhaust fan controllers mostly use a simple relay control method, which receives signals from floor smoke sensors, temperature sensors, manual operations, etc., and outputs control signals to start and stop the fan after logical operations. However, this method has problems such as single function, few external interfaces, poor anti-interference ability, large controller size that is not easy to install, and insufficient detection ability. In emergency situations such as fires, these problems may lead to poor smoke exhaust effects and even endanger personnel safety. Utility Model Content
