## Abstract

A smart control system for monitoring a bathroom includes a server, a smart toilet, a smart door handle, and a roller. The smart toilet includes a first sensor configured to detect whether the smart toilet is clean and send a first detection result to the server. The smart door handle includes a second sensor configured to detect whether the door of the bathroom is in an open state or a closed state and send a second detection result to the server. The roller includes a third sensor configured to detect a usage of the toilet paper on the roller and send a third detection result to the server. The server analyzes the first detection result, the second detection result, and the third detection result to obtain an analysis result. The server performs corresponding operations according to the analysis result.

## Claims

### Claim 1

A smart control system for monitoring a bathroom, the smart control system comprising:
a server;
a smart toilet mounted in the bathroom;
a smart door handle mounted on a door of the bathroom; and
a roller mounted in the bathroom and configured to hold toilet paper; wherein:
the smart toilet comprises a first sensor configured to detect whether the smart toilet is clean and send a first detection result to the server;
the smart door handle comprises a second sensor configured to detect whether the door of the bathroom is in an open state or a closed state and send a second detection result to the server;
the roller comprises a third sensor configured to detect a usage of the toilet paper on the roller and send a third detection result to the server;
the server analyzes the first detection result, the second detection result, and the third detection result to obtain an analysis result; and
the server performs corresponding operations according to the analysis result.

### Claim 2 (depends on 1)

The smart control system of claim 1, wherein:
when the analysis result indicates that the smart toilet is in a clean state, the door of the bathroom is in the open state, and an amount of toilet paper on the roller is sufficient, the server sends a message to a mobile terminal to indicate that the bathroom is not occupied;
when the analysis result indicates that the door of the bathroom is in the closed state, regardless of whether the smart toilet is in a clean state and whether the amount of toilet paper on the roller is sufficient, the server sends a message to the mobile terminal to indicate that the bathroom is currently occupied;
when the analysis result indicates that the smart toilet is in an unclean state and the door of the bathroom is in the open state, regardless of whether the amount of toilet paper on the roller is sufficient, the server sends a message to the mobile terminal to indicate that the bathroom needs to be cleaned.

### Claim 3 (depends on 1)

The smart control system of claim 1, wherein:
when the analysis result indicates that the smart toilet is in an unclean state, regardless of whether the door of the bathroom is in the open state, the server controls the smart toilet to perform automatic flushing and deodorization.

### Claim 4 (depends on 1)

The smart control system of claim 1, wherein:
the first sensor comprises a camera and a gas sensor;
the second sensor comprises a proximity sensor; and
the third sensor comprises a weight sensor or a proximity sensor.

### Claim 5 (depends on 1)

The smart control system of claim 1 further comprising an indicator light mounted on the smart door handle, wherein:
when the analysis result indicates that an amount of toilet paper on the roller is sufficient and the door of the bathroom is in the open state, the indicator light displays a first color;
when the analysis result indicates that the amount of toilet paper on the roller is less than sufficient and the door of the bathroom is in the open state, the indicator light displays a second color;
when the analysis result indicates that the door of the bathroom is in the closed state, regardless of the amount of toilet paper on the roller, the indicator light displays a third color.

### Claim 6

A smart control method for monitoring a bathroom, the smart control method comprising:
detecting whether a smart toilet mounted in the bathroom is clean and generating a first detection result;
detecting whether a door of the bathroom comprising a smart door handle mounted on an outer side of the door is in an open state or a closed state and generating a second detection result;
detecting a usage of toilet paper on a roller mounted in the bathroom and generating a third detection result;
analyzing the first detection result, the second detection result, and the third detection result to obtain an analysis result; and
performing corresponding operations according to the analysis results.

### Claim 7 (depends on 6)

The smart control method of claim 6 further comprising:
sending a message to a mobile terminal, when the analysis result indicates that the smart toilet is in a clean state, the door of the bathroom is in the open state, and an amount of toilet paper on the roller is sufficient, to indicate that the bathroom is not occupied;
sending a message to the mobile terminal, when the analysis result indicates that the door of the bathroom is in the closed state, regardless of whether the smart toilet is in a clean state and whether the amount of toilet paper on the roller is sufficient, to indicate that the bathroom is currently occupied;
sending a message to the mobile terminal, when the analysis result indicates that the smart toilet is in an unclean state and the door of the bathroom is in the open state, regardless of whether the amount of toilet paper on the roller is sufficient, to indicate that the bathroom needs to be cleaned.

### Claim 8 (depends on 6)

The smart control method of claim 6 further comprising:
controlling the smart toilet, when the analysis result indicates that the smart toilet is in an unclean state, regardless of whether the door of the bathroom is in the open state, to perform automatic flushing and deodorization.

### Claim 9 (depends on 6)

The smart control method of claim 6 further comprising:
displaying, by an indicator light when the analysis result indicates that an amount of toilet paper on the roller is sufficient and the door of the bathroom is in the open state, a first color;
displaying, by the indicator light when the analysis result indicates that the amount of toilet paper on the roller is less than sufficient and the door of the bathroom is in the open state, a second color;
displaying, by the indicator light when the analysis result indicates that the door of the bathroom is in the closed state, regardless of the amount of toilet paper on the roller, a third color.
