Embodiment 1

[0027] see figure 1 As shown, it is a schematic flowchart of Embodiment 1 of the water outlet control method of the drinking water supply device of the present invention. Such as figure 1 As shown, the water outlet control method of the drinking water supply device in this embodiment includes the following steps:

[0028] Step S101: Obtain the echo signal detected by the ultrasonic sensor, wherein the ultrasonic sensor is set at the water outlet of the drinking water supply device;

[0029] The number of ultrasonic sensors can be selected according to actual needs. In order to realize the automatic control of the water outlet, at least two ultrasonic sensors are generally required. For this reason, in one of the embodiments, the number of the ultrasonic sensors includes at least two, wherein , one ultrasonic sensor is used to emit ultrasonic waves, and at least one ultrasonic sensor is used to receive ultrasonic waves, that is, one ultrasonic sensor can be used to emit ultra...

Embodiment 2

[0045] Since only the height of the water surface and the height of the container along the height are required to control the water outlet of the drinking water supply device, that is, the propagation speed of the ultrasonic wave is a constant value, so the above-mentioned water surface height and the height of the container along the height can also be characterized by the propagation time. Correspondingly, The distance between the ultrasonic sensor and the shelf of the drinking water supply device is also characterized by propagation time, and the echo signal collected is the corresponding relationship between propagation time and intensity, which can greatly simplify the calculation process. For this reason, in In one embodiment, the distance may be replaced by the first propagation time of the ultrasonic wave from the ultrasonic sensor to the shelf, and the height along the container may be replaced by the first difference between the first propagation time and the second p...

Embodiment 3

[0057] Considering that the thickness of the container edge is often relatively small, the signal reflected by the ultrasonic waves along the container edge is very weak. In order to determine the accuracy of the measurement, the height of the container edge of the water container can be determined according to the echo signal and the distance. , first amplify the echo signal with a larger amplification factor, and then determine the container edge height of the water container according to the amplified echo signal; therefore, in this implementation, in different processing stages, the echo signal Perform different magnifications.

[0058] see Figure 4 Shown is a schematic flowchart of Embodiment 3 of the water outlet control method of the drinking water supply device of the present invention. Such as Figure 4 As shown, the water outlet control method of the drinking water supply device in this embodiment includes the following steps:

[0059] Step S301: Obtain the echo ...

Abstract

The invention provides a water outlet control method and system of a drinking water supply device. The water outlet control method includes the steps of obtaining echo signals detected by ultrasonic wave sensors, wherein the ultrasonic wave sensors are arranged on a water outlet of the drinking water supply device; judging whether a water container is arranged between the water outlet and a shelf or not according to the echo signals and the distance between the pre-stored ultrasonic wave sensors and the shelf of the drinking water supply device; if the water container is arranged between the water outlet and the shelf, determining the height of the container edge of the water container according to the echo signals and the distance; determining the height of the surface of water in the water container according to the echo signals and the distance; and controlling the water outlet of the drinking water supply device according to the height of the container edge and the height of the surface of the water. A user can conveniently use the drinking water supply device like a water dispenser, a water purification machine and the like by adopting the water outlet control method and system; in addition, the water outlet control method and system can be suitable for various water containers with uncertain volumes according to the scheme of the invention.

Description

technical field [0001] The invention relates to the technical field of automation control, in particular to a water outlet control method and system of a drinking water supply device. Background technique [0002] Drinking water dispenser, water purifier etc. are all drinking water supply devices that are often used in daily life, and general drinking water supply device is provided with water outlet, and water outlet switch is set at water outlet place, and this water outlet switch is mechanical device. When taking water, the user needs to manually control the water outlet switch, first open the water outlet switch, and then close the water outlet switch after the water is poured to a certain height. This way of use is very inconvenient because the user needs to bend down and wait for the water to be filled in front of the water dispenser, water purifier, etc., and when getting hot water, it is easy to cause injury to the person due to splashing of boiling water, and there ...
