Monitoring system for an apparatus for making beverages
A monitoring system for an apparatus for making beverages is provided, comprising a sensor unit having at least one sensor to determine current sensor data of a beverage production environment, a processing unit to determine current feature data from the current sensor data and a monitoring unit adapted to determine a current beverage production state by comparing the current feature data with reference feature data of a reference beverage production process. A control unit is adapted for controlling actuators in dependence of a current beverage production state determined by the monitoring unit.
1. A system, comprising:
a sensor arranged to capture an image of a top surface of a beverage being poured;
a monitoring and control subsystem, including a processor, configured to:
determine a state of the beverage being poured according to a classification of pixels representing the top surface; and
control an actuator to adjust pouring of the beverage in response to the state of the beverage that was determined according to the classification of pixels representing the top surface to signal an apparatus to preselect a beverage making program based on a size or type of an identified beverage container or to stop dispensing the beverage based on an identified container filling state,
wherein the state of the beverage being poured according to the classification of pixels includes a speed at which foam at the top surface of the beverage is rising by repeatedly identifying the filling state.
2. The system of claim 1 , wherein the actuator controls a pressure under which the beverage is being poured.
3. The system of claim 1 , wherein the actuator is additionally to control placement of a beverage container into a dispensing area.
4. The system of claim 1 , wherein the captured image represents a coffee beverage being poured, and wherein the determined state of the coffee beverage being poured indicates that unsuitable coffee beans or unsuitable ingredients were used during execution of the beverage making program.
5. The system of claim 1 , wherein the beverage comprises a drinkable food or a soup.
6. The system of claim 1 , wherein the actuator controls a fill level based on an extraction level based on the color of the top surface of the beverage.
7. The system of claim 1 , wherein the classification is according to a classifier trained with training images associated with respective states of the beverage being poured.
8. The system of claim 1 , wherein the monitoring and control subsystem is further configured to classify a type of beverage container to be filled, wherein the classification of the pixels representing the top surface is performed according to the type of beverage container.
9. The system of claim 1 , wherein the monitoring and control subsystem is further configured to identify the image from the sensor as including an empty beverage container holding area, and to control the actuator based on the image from the sensor including the empty beverage container holding area.
10. The system of claim 1 , wherein the beverage making program includes processing of a mashed or mixed food item.
11. A system, comprising:
a sensor arranged to capture an image of a dispensing area;
a monitoring and control subsystem, including a processor, configured to:
determine a current beverage production state according to a classification of pixels representing the dispensing area, wherein the state of the beverage being poured according to the classification of pixels includes a speed at which foam at the top surface of the beverage is rising by repeatedly identifying the filling state; and
control an actuator to prevent pouring of the current beverage in response to the classification indicating that the dispensing area is empty.
12. The system of claim 11 , wherein the monitoring and control system is additionally configured to:
initiate execution of a beverage making program based on a size or type of an identified beverage container in the dispensing area.
13. The system of claim 11 , wherein the monitoring and control system is additionally configured to:
stop dispensing the current beverage based on an identified container filling state.
14. The system of claim 11 , wherein the monitoring and control system is additionally configured to:
control a placement of a beverage container into the dispensing area.
15. A method, comprising:
capturing an image of a top surface of a beverage being poured;
determining a state of the beverage being poured according to a classification of pixels representing the top surface;
controlling an actuator to adjust pouring of the beverage in response to the state of the beverage that was determined according to the classification of pixels representing the top surface; and
signaling an apparatus to preselect a beverage making program to pour the beverage based on a size or type of an identified beverage container or stopping pouring of the beverage based on an identified container filling state,
wherein the state of the beverage being poured according to the classification of pixels includes a speed at which foam at the top surface of the beverage is rising by repeatedly identifying the filling state.
16. The method of claim 15 , wherein the state of the beverage being poured according to the classification of pixels includes a color of the top surface.
17. The method of claim 16 , wherein the state of the beverage being poured includes the state of a drinkable food being poured into the identified beverage container.
