Step 1: In the morning, the director of the company swipes his card to pass through the gate of the park and the gate of the office building successively, and the access control system reports the swiped card information to the central control unit.

Step 2: The central control unit finds that the time interval between the supervisor's two card swipes is < T1, and based on the predefined behavior pattern, determines that the supervisor is about to arrive at the office.

Step 3: The central control unit queries the environmental attributes of the supervisor's office, and the environmental sensor reports that the air quality is poor, the room temperature is 29 degrees, and the brightness is low.

Step 4: The central control unit queries the user model and obtains that the room temperature preferred by the supervisor is 24 degrees. The current room temperature is obviously not in line with the user's preference; the data reported by the smart bracelet worn by the supervisor shows that the user's health status is normal (no fever). Therefore, the central control unit judges that it is necessary to lower the room temperature, improve the air quality and brightness, and obtain the cooling function of the AC, the purification function of the cleaner, and the switching function of the curtain by querying the indoor environment model.

Step 5: The central control unit automatically sends a start-up command to the air conditioner with the function mode set to cooling and a target temperature of 24 degrees; sends a start-up command to the air purifier with the function mode set to purification; and sends an open command to the smart curtains.

Step 6: At noon, the central control unit inquired that the current outdoor temperature was 37 degrees. According to the expert knowledge base "Using air conditioners for cooling, the temperature difference between indoor and outdoor should not exceed 10 degrees", the central control unit automatically raised the target temperature of the air conditioner to 27 degrees; The data reported by the smart bracelet shows that the supervisor has entered a sleep state, and the central control unit automatically closes the smart curtains.

Step 7: The supervisor leaves the office and passes through the gate of the office building and the park successively by swiping the card. The access control system reports the swiping information to the central control unit; the central control unit finds that the time interval between the supervisor’s two swipes of the card is < T1, and based on the predefined behavior pattern, decides The executive leaves the company.

Step 8: If the access control system does not report the supervisor's card information within the preset T2 time, the central control unit determines that the supervisor has left the company for a long time, and automatically sends a shutdown command to the air conditioner and air purifier, and sends a shutdown command to the smart curtain.
