Example Embodiment
[0057] Example 1
[0058] The sensor is installed and fixed on the main shaft of the stepper motor, and the sensor scans in ∠γ with the main shaft of the stepper motor, such as figure 2 As shown, it is preferable to scan within 60°.
[0059] When the sensor scans in ∠γ, the sensor reads the temperature once every time the stepper motor rotates through the angle φ, and records the highest temperature value and the stepping motor rotation angle λ where the highest temperature value is read, where λ is an integer multiple of the angle φ , The priority 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 urine is calculated.
[0061] α=|γ / 2-λ|, X=(L1 / COSμ)*TAN(|γ / 2-λ|).
[0062] In the same way, we can calculate β=|δ / 2-ω|, Y=(L2 / COSξ)*TAN(|δ / 2-ω|).
Example Embodiment
[0063] Example 2
[0064] The sensor is installed and fixed on the main shaft of the stepper motor, and the sensor scans in ∠γ with the main shaft of the stepper 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 and the lowest temperature, as well as the stepper motor rotation angle λ that reads the highest temperature.
[0066] Whenever the sensor reaches the boundary of ∠γ, such as image 3 As shown, the temperature difference between the highest temperature and the lowest temperature of the sector is calculated. If the temperature difference is greater than 3°C, calculate the location of the urine. Experiments show that when the temperature difference is greater than 3℃, the accuracy of calculating the position of urine is higher.

Example Embodiment
[0069] Example 3
[0070] The sensor is installed and fixed on the main shaft of the stepper motor, and the sensor scans in ∠γ with the main shaft of the stepper 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 higher.
[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 lowest temperature, as well as the stepper motor rotation angle λ that reads the highest temperature.
[0073] Whenever the sensor reaches the lower boundary of a sector, such as Figure 5 As shown, the temperature difference between the highest temperature and the lowest temperature of the sector is calculated. If the temperature difference is greater than 3°C, calculate the location of the urine.
