摘要
传统空调风口通常采用固定朝向或简单手动调节方式，冷风直吹人体易引起关节疼痛、感冒等健康问题。针对该问题，本文设计了一种基于60GHz毫米波雷达的智能空调风口控制系统，系统硬件以HR8P506微控制器为主控，通过毫米波雷达传感器获取最多10人的空间坐标，采用步进电机驱动风口摆叶，集成红外遥控、ADC风动检测等辅助模块。本文提出了一种基于高斯核空间占有概率建模与人工势场法相结合的风向优化算法，将离散人体坐标映射至100点空间网格并生成连续可微的高斯排斥概率分布，多人概率叠加后通过势能最小化求解最优送风方向，引入边缘偏好修正因子使风口在势能接近时优先偏向房间边缘。相比传统二值化禁吹区方案，该算法避免了方向硬跳变和禁吹区过度膨胀问题，时间复杂度为O(N×100)，在Cortex-M0上执行时间小于 0.1ms。仿真验证了多种分布场景下算法的正确性，现场测试表明风口偏转方向正确率达 95% 以上，满足风避人吹设计要求。
Abstract
Conventional air-conditioning vents typically employ a fixed orientation or simple manual adjustment, which often directs cold airflow straight toward occupants, potentially causing joint pain, common cold, and other health issues. To address this problem, this paper presents an intelligent air-conditioning vent control system based on a 60 GHz millimeter-wave (mmWave) radar. The hardware platform is built around an HR8P506 microcontroller, which acquires the spatial coordinates of up to 10 occupants via a mmWave radar sensor, drives the vent louvers through a stepper motor, and integrates auxiliary modules including an infrared remote receiver and an ADC-based airflow detection circuit. A novel airflow-direction optimization algorithm combining Gaussian-kernel spatial occupancy probability modeling with the artificial potential field (APF) method is proposed. Specifically, discrete human-body coordinates are mapped onto a 100-point spatial grid to generate a continuous and differentiable Gaussian repulsion probability distribution. After superimposing the probability fields of multiple occupants, the optimal supply-air direction is obtained by minimizing the total potential energy. An edge-preference correction factor is further introduced so that the vent preferentially deflects toward the room periphery when potential energies in competing directions are comparable. Compared with conventional binary no-blow-zone schemes, the proposed algorithm eliminates abrupt directional jumps and excessive expansion of forbidden regions. Its time complexity is O(N × 100), and the execution time on a Cortex-M0 core is less than 0.1 ms. Simulation results verify the correctness of the algorithm under various occupant distribution scenarios. Field tests demonstrate that the vent deflection direction achieves an accuracy exceeding 95%, satisfying the design requirement of wind-avoiding-human blowing.关键词
