Embodiment 1

[0058] The sensor is installed and fixed on the main shaft of the stepping motor, and the sensor scans within ∠γ along with the main shaft of the stepping motor, such as figure 2 As shown, it is preferable to scan in the range of 60°.

[0059] When the sensor scans within ∠γ, every time the stepper motor rotates through the φ angle, the sensor reads the temperature once, and records the highest temperature value and the stepping motor rotation angle λ at which the highest temperature value is read, where λ is equal to an integer multiple of the φ angle , the preferred value of φ angle is 0.04*frequency*step angle.

[0060] Whenever the sensor reaches the boundary of ∠γ, as shown in Figure 3, the position of the urine is calculated.

[0061] α=|γ / 2-λ|, X=(L1 / COSμ)*TAN(|γ / 2-λ|).

[0062] Similarly, β=|δ / 2-ω|, Y=(L2 / COSξ)*TAN(|δ / 2-ω|) can be calculated.

Embodiment 2

[0064] The sensor is installed and fixed on the main shaft of the stepping motor, and the sensor scans within ∠γ along with the main shaft of the stepping motor, such as figure 2 shown.

[0065] When the sensor scans within ∠γ, the sensor reads the temperature once every time the stepper motor rotates through the φ angle, and records the highest temperature value and the lowest temperature, as well as the stepping motor rotation angle λ at which the highest temperature value is read.

[0066] Whenever the sensor reaches the boundary of ∠γ, such as image 3 As shown, calculate the temperature difference between the highest temperature and the lowest temperature in this sector. If the temperature difference is greater than 3°C, calculate the location of the urine. Experiments show that the accuracy of calculating the urine position is higher when the temperature difference is greater than 3°C.

Embodiment 3

[0070] The sensor is installed and fixed on the main shaft of the stepping motor, and the sensor scans within ∠γ along with the main shaft of the stepping motor, such as figure 2 shown.

[0071] In ∠γ, every 5° is a sector, and the whole ∠γ is divided into N sectors, such as Figure 4 As shown, the experiment proves that 5° is a sector, and the calculation efficiency is high.

[0072] When the sensor scans within ∠γ, the sensor reads the temperature once every time the stepper motor rotates through the φ angle, and records the highest temperature and the lowest temperature, as well as the stepping motor rotation angle λ at which the highest temperature is read.

[0073] Whenever a sensor reaches the lower boundary of a sector, such as Figure 5 As shown, calculate the temperature difference between the highest temperature and the lowest temperature in this sector. If the temperature difference is greater than 3°C, calculate the location of the urine.

Abstract

The invention discloses a method for automatically positioning urine. The position of the urine is determined according to the result of temperature scanned by a non-contact temperature sensor, and position point coordinates of the urine in a closestool are calculated. The invention further discloses a device for automatically positioning the urine. From the perspective of a virtual module framework, the device comprises an automatic urine positioning module adopted in the method; from the perspective of a solid structure, the device comprises one or more sets of positioning assemblies, and the positioning assembly comprises the non-contact temperature sensor connected with a stepping motor spindle. The invention further discloses the closestool comprising the device for automatically positioning the urine. The point coordinates of the urine are determined according to the temperature (the urine temperature or both the urine temperature and the environment temperature) scanned by the non-contact temperature sensor, the urine is sucked in the air to serve as a sample for health analysis, the problem of cross contamination caused by suction of the urine sample on the inner surface of the closestool is avoided, accuracy of health data analysis is improved, and the method, the device and the closestool are suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of intelligent toilets, in particular to a method and device for automatically positioning urine and a healthy intelligent toilet containing the same. Background technique [0002] With the improvement of people's living standards, smart toilets have gradually entered people's lives. In addition to satisfying comfort, smart toilets have added health monitoring functions, such as collecting urine samples for health data analysis. However, using urine collected on the inner surface of the toilet for testing will have cross-contamination problems, which will affect the accuracy of health data analysis. Therefore, how to avoid the cross-contamination problem of drawing urine samples on the inner surface of the toilet so as to improve the accuracy of health data analysis has become an urgent problem to be solved. Contents of the invention [0003] The first technical problem to be solved by the present invention is to ...
