AI Technical Summary

Technical Problem

Existing Bluetooth sensing solutions for smart air conditioners suffer from MAC randomization, RSSI fluctuations, and insufficient behavioral adaptation, making it impossible to reliably identify the presence of devices. This results in the air conditioner's automatic control accuracy and energy-saving effect failing to meet actual needs.

Method used

By acquiring the broadcast packets and signal strength of Bluetooth devices, multiple types of feature information are extracted to construct device fingerprints. Based on the device fingerprints, similarity matching is performed to associate random MAC addresses. Combined with signal strength filtering, the device's presence status is determined, and an air conditioning control strategy is generated and executed.

Benefits of technology

It improves the accuracy of the air conditioner in recognizing the user's presence, enhances the intelligence of air conditioner control, and balances user comfort with energy efficiency.

Abstract

The invention discloses an air conditioner control method, device and system, a storage medium and a computer program product. The method comprises the steps that a broadcast packet of Bluetooth equipment and the signal strength of the broadcast packet are obtained; extracting multiple types of feature information in the broadcast packet to construct a device fingerprint; performing similarity matching based on the device fingerprint to associate the random MAC address in the broadcast packet with the same Bluetooth device to obtain an association result; filtering the signal intensity, and judging the existence state of the Bluetooth equipment according to the filtered signal intensity and the association result; and generating and executing a control strategy of the air conditioner according to the existence state. According to the scheme, the equipment existence recognition reliability of the air conditioner is improved, the automatic control precision of the air conditioner is improved, and the energy-saving effect and the user comfort experience are enhanced.
