The controller is respectively in signal connection with the microwave induction assembly and the flushing assembly and is used for acquiring detection data from the microwave induction assembly and flushing the water according to the detection data.
The microwave induction component is arranged at the rear part of the trap 11 of the body, the position of the microwave induction component is located on a plane, the plane refers to a preset accumulated water level when the trap accumulates water, and the plane can be finely adjusted according to actual conditions and field calibration conditions, so that the plane is lower than the water level or higher than the water level for certain correction value.
The microwave induction assembly comprises an antenna module, wherein the antenna module comprises a transmitting antenna and a receiving antenna, the transmitting antenna is used for transmitting electromagnetic waves, the receiving antenna is used for receiving reflected electromagnetic waves, the transmitting antenna is used for transmitting the electromagnetic waves forwards, the electromagnetic waves are detected by the receiving antenna after being reflected, the detection data are generated, and the detection data are sent to the controller.
The microwave induction assembly is positioned on the rear wall of the body, and a cavity for accommodating the microwave induction assembly is arranged on the rear wall. The structure of this cavity can be regarded as a sunk structure of back wall in fact, and this cavity department wall thickness is thinner, and is thinner than adjacent position promptly, can make things convenient for the installation of microwave response subassembly through setting up this cavity, and in addition, thicker wall thickness can influence the transmission distance of electromagnetic wave, but too thin can influence the bulk strength of urinal, can also avoid causing too big influence to the transmission of electromagnetic wave on the basis of guaranteeing urinal bulk strength through setting up this cavity.
As shown in fig. 2a, under normal conditions and under the condition of no water blockage, when the accumulated water in the water does not cover the microwave emission path, the electromagnetic wave emitted by the microwave sensing assembly sequentially penetrates through the air, the ceramic and the air to reach the human body, wherein the difference between the dielectric constants of the air and the ceramic is not large, but the difference between the dielectric constants of the air and the human body is large, and the human body reflects a large amount of microwaves, so that the microwave sensing assembly can normally detect the spatial position of the human body.
Under the condition of water blockage, as shown in fig. 2b, at the moment, the transmission path of the electromagnetic wave is shielded by the accumulated water at the trap of the urinal, the electromagnetic wave sequentially passes through the air, the ceramic and the water and can hardly reach the human body, wherein the difference between the dielectric constants of the air and the ceramic is not large, the microwave can penetrate through the water, but the difference between the dielectric constants of the ceramic and the water is large, and the microwave can hardly penetrate through the water, so that the human body can not be accurately detected.
Based on the analysis, the detection data output by the microwave sensing assembly is different when water is blocked and water is not blocked, when the controller receives the detection data, the controller outputs a corresponding flushing control signal to the flushing assembly based on the detection data, the flushing control signal is used for controlling the flushing assembly to normally flush when a human body is detected to be close under the condition that the urinal is not blocked, and the flushing assembly is controlled to avoid flushing under the condition that water is blocked.

The control signal output end is used for outputting a flushing control signal so that the controller controls the flushing assembly according to the first distance.
In implementation, the controller first determines a first distance, where the determination is to compare the first distance with a preset jam distance threshold value a. The preset blocking distance threshold A is not more than the distance between the foremost end of the urinal body and the microwave induction assembly and is more than the distance between the microwave induction assembly and accumulated water in the urinal when the urinal is blocked.
When the first distance is smaller than the preset blocking distance threshold value A, the urinal is judged to be blocked, and the flushing component is controlled not to flush water at the moment so as to avoid sewage overflow.
Through the control, whether the blockage occurs can be accurately judged, the action of the flushing component is controlled according to the blockage condition, namely the controller stops flushing under the flushing condition, and the corresponding flushing instruction is refused to be executed under the flushing condition so as to achieve the effect of avoiding the overflow of sewage.
The controller is also used for controlling the flushing component to carry out pre-flushing through the flushing control signal.
By re-determining the first distance, when the first distance is greater than the preset blockage distance threshold a and less than the first distance threshold T _ in, as shown in fig. 5, the flushing assembly is controlled to perform pre-flushing, or pre-wet the surface of the urinal. Through the operation, the surface of the urinal can be pre-wetted, urine is prevented from directly contacting the surface, and the urine can be conveniently flushed clean after subsequent flushing.
The controller is also used for controlling the flushing component to flush again through the flushing control signal.
And when the first distance is greater than a second distance threshold value T _ out, controlling the flushing component to flush again. At this time, the actual scenario generally corresponds to the stage that the user leaves after urinating, and the flushing assembly is controlled to flush again to clean the surface of the urinal. The urinal can be cleaned by flushing water again, so that the urinal keeps clean and sanitary, and dirt on the surface of the urinal is avoided.

The morphological data herein includes, but is not limited to, some or all of the flow rate parameters, thickness parameters and discontinuity parameters of the urine column. The specific embodiment is shown in FIG. 7.
The controller estimates the urine health state based on the shape data.
Namely, the form data is processed based on the urine health state evaluation algorithm to obtain the urine health information of the user, and the urine health information is output through the health signal output end. When the controller processes the detection signal, the controller judges that the urine column is unhealthy by detecting the continuity characteristic of the urine column when the number of times of interruption of the urine column is higher than a certain value; judging the urine column flow speed characteristic as unhealthy when the average flow speed is lower than a health value counted in advance; the reflected wave energy can be referred to for the urine column thickness parameter, and unhealthy is judged when the average reflected wave energy is lower than the health value counted in advance.
The embodiment can obtain the urine health information of the user by judging the urine form data of the user, and output the urine health information under the condition that the information output module exists in the urinal, so that the user can know the health state of the user in time.
