Intelligent closestool automatic control method based on millimeter wave induction
The invention provides an intelligent closestool automatic control method based on millimeter wave induction, and the method comprises the steps: transmitting an intermediate frequency signal through a radar, receiving a reflected signal, and achieving the precise capturing and recognition of a user behavior, and firstly obtaining the distance information of a target through fast Fourier transform; then, the speed weight and the track speed weight of the target are calculated to judge the gesture of the user, speed weight data are smoothed through Kalman filtering, the gesture recognition accuracy is improved, and when the gesture of the user is successfully matched with preset gesture template data, the intelligent closestool executes corresponding actions such as automatic uncovering or flushing; in addition, the system also records the result of each gesture recognition and the response condition of the closestool, so that the gesture recognition algorithm and the closestool control logic are continuously optimized and improved, and the intelligent level and the user experience of the intelligent closestool are improved.
本发明提出了一种基于毫米波感应的智能马桶自动控制方法，通过雷达发射中频信号并接收反射回来的信号，实现对用户行为的精准捕捉和识别，该方法首先通过快速傅里叶变换获取目标的距离信息，然后计算目标的速度权重和轨迹速度权重，以判断用户手势，利用卡尔曼滤波对速度权重数据进行平滑处理，提高手势识别的准确性，当用户手势与预设的手势模板数据匹配成功时，智能马桶将执行相应的动作，如自动开盖或冲洗，此外，系统还会记录每次手势识别的结果和马桶响应情况，以便对手势识别算法和马桶控制逻辑进行持续的优化和改进，从而提升智能马桶的智能化水平和用户体验。
