In one possible embodiment, the guest room basic information is obtained by retrieving guest room data in a hotel guest room management system. The guest room basic information is information describing the real-time state of the guest room and comprises power taking state information and registration state information. The power taking state information is information describing whether a circuit in the guest room is communicated with a hotel circuit or not and the state of supplying power to the guest room. Preferably, the guest room typically uses a power card or the like to connect the electrical circuit in the guest room to the hotel electrical circuit to supply power to guests in the guest room. And when the power taking state information is in the power-off state, indicating that no power is supplied in the guest room, and when the power taking state information is in the power taking activation state, indicating that the power is supplied in the guest room. The registration state information is information describing a state of whether a guest room has a guest to check in. When the registration state is displayed as registered, indicating that a guest in the guest room is checked in; when the registration state is displayed as a non-registration state, it indicates that no tenant in the guest room is registered for check-in, and the guest room should be in an empty state. By acquiring basic information of the guest room, a basic analysis basis is provided for subsequent analysis of whether the pre-warning behavior of the guest room exists in the guest room.
In one embodiment, the abnormal power taking guest room is determined as a monitoring object by analyzing the power taking state of the guest room according to the guest room basic information and combining the registration state information, and then whether the guest room has the phenomenon of a flying guest room is determined by analyzing the posture of a human body in the guest room. The method realizes the goal of multidimensional and efficient analysis and determination of the early warning behavior of the flyer house.
In one possible embodiment, when the registration state information of the guest room belongs to a non-registration state and the power taking state information belongs to a power taking activation state, the activation duration from the power taking activation time point in the guest room to the current time point is extracted from the hotel guest room management system.

The preset activation time is the longest time period that the preset guest room can be in the power-taking activation state in the non-registration state, and is set by the staff at will, and the preset activation time is not limited herein.

When the target distance characteristic meets the sensitive distance threshold, it indicates that the first monitored object is within the guest room, and not an object passing outside the guest room. Furthermore, when the target respiratory feature exists, or the target respiratory feature and the target heartbeat feature exist simultaneously, or the target heartbeat feature exists, the first monitoring object is indicated to be a human body, and the first monitoring object is added into the gesture monitoring object.
