The invention belongs to the technical field of intelligent closestools, and particularly relates to an FMCW-based intelligent closestool flushing method and an intelligent closestool, the method is based on the intelligent closestool and a microwave sensor, and the method comprises the steps that according to a preset fixed frequency range, the microwave sensor is controlled to conduct continuous frequency modulation and emit electromagnetic waves outwards; when a user is sensed by the emitted electromagnetic waves, reflected electromagnetic waves are generated after the electromagnetic waves are reflected by the user, and the reflected electromagnetic waves are received by the microwave sensor; performing frequency mixing on the currently received initial reflection electromagnetic wave and the modulated currently transmitted electromagnetic wave to obtain an intermediate frequency signal; performing signal processing on the intermediate frequency signal to obtain frequency spectrum information of the user; according to the frequency spectrum information, dynamic information of a user is obtained, the current posture of the user is judged according to the dynamic information of the user, and different flushing modes are selected according to the current posture of the user; meanwhile, water is saved, and environmental protection and energy conservation are achieved.
本发明属于智能马桶技术领域，尤其涉及一种基于FMCW的智能马桶冲水方法及智能马桶，所述方法基于智能马桶和微波传感器，所述方法包括：根据预设的固定频率范围，控制微波传感器进行连续调频，向外发射发射电磁波；当发射电磁波感应到使用者时，经使用者反射后产生反射电磁波，由微波传感器接收反射电磁波；通过当前接收到的初始反射电磁波与调制后的当前发射电磁波，混频后得到中频信号；对中频信号进行信号处理，得到使用者的频谱信息；根据频谱信息，获取使用者动态信息，通过使用者动态信息判断使用者当前姿态，由使用者当前姿态选择不同的冲水模式；提高智能马桶的智能化和卫生程度同时节约用水，环保节能。
