Can fan speed be determined without modifying the fan? SingTown's visual solution makes it possible.

SingTown基於OpenMV嘅智能相機系統能夠識別風扇係咪處於旋轉狀態，並計算其轉速。透過人工智能同機器視覺演算法，系統實時捕捉葉片運動軌跡，分析旋轉頻率，並輸出風扇啟停狀態同轉速等級。佢適用於工業監測、節能控制同實驗測試等多種場景。

In industrial sites or equipment management, accurately determining the operational status and speed levels of fans is a crucial aspect of equipment safety and energy-saving management. SingTown Technology's intelligent camera solution, based on the OpenMV platform, integrates edge-side AI image recognition and computer vision algorithms to achieve non-contact, real-time monitoring of fan operation.

The system continuously captures images of the fan through the camera, analysing the motion blur, angle changes, and periodic brightness characteristics of the blades. When periodic motion trajectories are detected, the system can automatically determine that the fan is in a rotating state and estimate the rotational speed level based on the rate of change between frames. Unlike traditional contact sensors, this solution enables non-contact detection without requiring any modifications to the fan itself.

The system can stably identify fans of different sizes and colours, unaffected by ambient light (such as in factory workshops, outdoor equipment points, inside ventilation systems, etc.). Additionally, the system supports customisable thresholds to distinguish between low-speed, normal, and overspeed operating states.

OpenMV智能相機支援高速採樣及邊緣端AI本地化運算，具備邊緣部署能力，尤其適用於風扇單元、冷卻塔、實驗裝置及智能家居等場景。結合控制系統，可在風扇出現異常停轉或超速時自動發出警報或調節功率，實現安全與節能的雙重目標。

SingTown將人工智能同機器視覺技術融入日常設備監測，令OpenMV智能相機成為智能監控同工業自動化嘅高效嵌入式視覺感知核心。
