The water heater control method, device and water heater according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a water heater control method according to an embodiment of the present invention. In an embodiment of the invention, the water heater may comprise an electric water heater.

As shown in Figure 1, the water heater control method of the embodiment of the present invention includes the following steps:

S1, projecting the operation panel of the water heater to display the operation panel in a preset projection area. Wherein, the preset projection area can be calibrated according to the actual situation. For example, the preset projection area can be set on the wall below the water heater, and the height of the preset projection area on the wall can be reasonably adjusted according to the height of the user. calibration.

Specifically, after the water heater is powered on, the image recognition module in the water heater is activated. When the user wants to control the water heater, he can trigger the built-in water heater by waving his palm within a preset distance below the image recognition module. The projection device is used to project the operation panel of the water heater in a preset projection area, so as to facilitate user's operation. Wherein, the number and magnitude of the palm wave can be calibrated according to the actual situation.

In other embodiments of the present invention, when the water flow sensor built in the water heater detects the water flow at the water outlet of the water heater, the built-in projection device of the water heater can also be triggered to project the operation panel of the water heater in the preset projection area. For example, when a user turns on a faucet connected to a water heater, the water heater projects its own operation panel to display the operation panel on the wall below the water heater.

S2, using the image recognition module to detect whether a button on the operation panel displayed by the projection is triggered to obtain a user's control instruction.

Furthermore, in one embodiment of the present invention, the image recognition module detects whether the buttons on the operation panel for projection display are triggered to obtain the user's control instructions, which may specifically include the following steps:

S21. Detect position information relative to a preset image reference point when any button on the operation panel for projection display is triggered. Wherein, as shown in Figure 4, the preset image reference point is within the preset image recognition area, and the preset image recognition area can be a coordinate system with the preset image reference point as the origin (0,0), so that the image The identification module detects the location information of any button on the operation panel displayed by the projection in the preset image identification area when it is triggered.

In one embodiment of the present invention, detecting the position information relative to the preset image reference point when any button on the operation panel of the projection display is triggered includes scanning the preset projection area to detect whether the user touches the projection display operation panel, when the user touches the operation panel displayed by the projection, the image information of the preset image recognition area is acquired, wherein the preset projection area is within the preset image recognition area, and then it is determined according to the image information that the key to be triggered is relative to the preset The location information of the image reference point.

Further, determining the position information of the triggered key relative to the preset image reference point according to the image information includes parsing the image information to extract the feature of the image interest point, and combining the feature of the image interest point with each key in the preset database The image features are matched, and if the matching is successful, the position information of the triggered key relative to the preset image reference point is determined according to the image interest point features. Wherein, the preset database can be calibrated according to actual situation information. For example, the default database can be set when the water heater leaves the factory.

S22. Obtain a user's control instruction according to the location information.

S3, controlling the water heater according to the user's control instruction.

Specifically, when the water heater projects the operation panel of the water heater in the preset projection area, the water heater will scan the preset projection area in real time through the image recognition module to detect whether the user touches the projected and displayed operation panel. When the user triggers a button on the projected and displayed operation panel (for example, a water temperature adjustment button) with a finger, the water heater can determine that the user's finger has triggered the button on the projected and displayed operation panel through the image recognition module. At this time, the water heater will control the image recognition module to acquire the image information of the preset image recognition area (that is, take a picture of the preset image recognition area).

Then, the water heater analyzes the image information, extracts the image interest point features from the image information, and matches the image interest point features with the image features of each button in the preset database. If the matching is successful, then according to the image The feature of the point of interest determines the location information of the triggered key relative to the preset image reference point. Then the water heater obtains a control command according to the position information, and finally the water heater controls the water heater accordingly according to the control command. For example, adjusting the water temperature in an electric water heater. Wherein, the relationship between the position of each button in the laser dot matrix and the control instruction in the projected control panel can be pre-stored in the water heater.

It should be noted that when the water heater projects the operation panel of the water heater in the preset projection area, specific coordinate points can be projected in the projection area as corrections, and relevant correction actions can be performed if the user finds that the click is uncertain. The preset database described in this embodiment can be stored in the water heater (that is, locally), or can be stored in a cloud server connected to the water heater. When the preset database is stored in the water heater, it can avoid the phenomenon of recognition delay caused by slow network when using the network.

In addition, after the user completes the operation on the electric water heater, he can click the projection off button on the operation panel of the above-mentioned projection display to turn off the projection device of the water heater. In other embodiments of the present invention, if the user does not operate the above-mentioned projection display operation panel within 10 minutes, the water heater will also automatically turn off the projection device, so as to reduce unnecessary resource (power) waste.

To sum up, according to the water heater control method of the embodiment of the present invention, the operation panel of the water heater is first projected to display the operation panel in the preset projection area, and then the image recognition module is used to detect whether the keys on the projected and displayed operation panel are triggered To obtain the user's control instruction, and finally control the water heater according to the user's control instruction. Therefore, the method can control the water heater through the projected operation panel, thereby solving the problem of inconvenient control caused by the relatively high installation position of the water heater, and improving user experience.

In addition, the embodiments of the present invention also provide a computer-readable storage medium with instructions stored therein, and when the instructions are executed, the water heater implements the above water heater control method.

The computer-readable storage medium in the embodiment of the present invention first projects the operation panel of the water heater to display the operation panel in the preset projection area, and then uses the image recognition module to detect whether the keys on the projected and displayed operation panel are triggered to obtain user information. Finally, the water heater is controlled according to the user's control command, thereby solving the problem of inconvenient control of the water heater due to the relatively high installation position, and improving the user experience.
