[0037] In one embodiment, a human presence sensor provided by the technical solution of the present invention is as Figure 1 shown. The human presence sensor includes: a housing 1; a sensing unit 2, which is disposed inside the housing 1, and the sensing side of the sensing unit 2 can face a predetermined space in the room; a processor 3, which is disposed inside the housing 1, and the processor 3 is electrically connected to the sensing unit 2; a receiving unit 4, which is electrically connected to the processor 3, and the receiving unit 4 is signal-connected to a sensor 5 outside that can sense the opening and closing of the room door, and the sensor 5 that can sense the opening and closing of the room door is installed at the access door of the room.

[0038] Preferably, the sensor that can sense the opening and closing of the room door can be a door magnetic sensor or a device such as a smart door lock.

[0039] The sensing unit 2 is used to sense human body information in the room. The receiving unit 4 builds a signal bridge between the sensor 5 that can sense the opening and closing of the room door and the processor 3. After obtaining the two signals from the sensing unit 2 and the sensor 5 that can sense the opening and closing of the room door, the processor 3 comprehensively judges whether there is someone in the room.

[0040] The implementation of this technical solution can improve the accuracy of judging the presence or absence of people in the room.

[0041] Optionally, the sensing unit 2 is a radar. The radar has a more accurate ability to judge the presence or absence of a human body.

[0042] Optionally, the sensing unit 2 includes a radar and a pyroelectric sensor. The sensing unit 2 is a sensor including multiple types.

[0043] Optionally, the operating frequency band of the radar is 24 GHz or 60 GHz. Among them, the theoretical resolution of 24 GHz reaches 60 cm, which is sufficient to distinguish a human body, and both frequency bands belong to the ISM frequency band. It should be noted that 24 GHz and 60 GHz are not precise limiting values, but are brief or common statements taken for the convenience of explaining engineering concepts. For nearby ranges, for example, frequency bands within a fluctuation of 1 GHz up and down are also included.

[0044] Preferably, the radar in this embodiment is a millimeter-wave radar, or a quasi-millimeter-wave radar, such as a 24 GHz radar.

[0045] Optionally, the presence sensor is used in commercial passenger rooms or in home rooms. For example, in a small home room with a glass door, due to the penetration effect of the glass door and the small space, the presence sensor installed in such a room is vulnerable to activities in the external space, resulting in misjudgment. At this time, by installing a door magnetic sensor at the glass door of the home room and connecting the door magnetic sensor to the presence sensor, this kind of misjudgment can be avoided.

[0046] Optionally, the receiving unit 4 is wirelessly connected to the sensor 5 that can sense the opening and closing of the room door. The receiving unit 4 and the sensor 5 that can sense the opening and closing of the room door can also be connected by wire. In short, the signal of the sensor 5 that can sense the opening and closing of the room door should be transmitted to the receiving unit 4, so that the processor 3 can obtain the opening and closing status of the access door.

[0047] In one embodiment, the technical solution of the present invention also provides a presence sensor, which includes: a radar, the sensing side of the radar can face a predetermined space in the room; a processor 3, the processor 3 is electrically connected to the radar; a receiving unit 4, the receiving unit 4 is electrically connected to the processor 3, and the receiving unit 4 is signal-connected to an external sensor 5 that can sense the opening and closing of the room door, and the sensor 5 that can sense the opening and closing of the room door is installed at the access door of the room.

[0048] Optionally, the operating frequency band of the radar is 24 GHz or 60 GHz.

[0049] In one embodiment, the technical solution of the present invention also provides an auxiliary device for power supply in commercial passenger rooms, which includes: a radar, the sensing side of the radar can face a predetermined space in the room; a processor 3, the processor 3 is electrically connected to the radar, and the processor 3 is signal-connected to the power supply device of the commercial passenger room; a receiving unit 4, the receiving unit 4 is electrically connected to the processor 3; a sensor 5 that can sense the opening and closing of the room door, the sensor 5 that can sense the opening and closing of the room door is signal-connected to the receiving unit 4, and the sensor 5 that can sense the opening and closing of the room door is installed at the access door of the room.

[0050] Optionally, the power supply device can supply power without a card.

[0051] This embodiment can improve the accuracy of judging the presence or absence of people in the room, thus realizing a better cardless power supply mode and preventing the occurrence of incorrect power-off situations caused by misjudging that people are not present.

[0052] In one embodiment, a door magnetic signal is introduced for a 24 GHz radar. After the door is closed, the door magnetic signal is sent to the presence sensor, and the presence sensor is designed with an auxiliary prediction algorithm based on this signal.

[0053] The technical solution of this embodiment enhances the judgment accuracy of the cardless power supply system in hotels, avoiding the accidental shutdown of the power supply caused by misjudgment of the radar. Through the door magnetic signal assisted prediction algorithm, when the radar fails to detect minute human activities, it can still ensure that the room power supply system remains on, thereby reducing customer complaints, improving the user experience, and enhancing the system intelligence.

[0054] Simply relying on the 24GHz radar may fail to detect minute human activities (such as deep sleep or lying prone), while by combining the signal of the sensor 5 that can sense the opening and closing of the room door, it can be assisted in prediction through the time period after closing the door and the confidence threshold, ensuring that even when the radar signal is briefly lost, it can be inferred that there is someone in the room.

[0055] Through the door magnetic signal and the confidence algorithm, even when the radar fails to detect minute human activities, the system can still judge whether there is still someone in the room based on historical data, thereby avoiding mistakenly turning off the room power supply due to the mistaken belief that the room is unoccupied. This greatly reduces the risk of customer complaints caused by accidental power off.

[0056] By triggering the prediction algorithm through the door magnetic signal, the system can manage the power in the room more intelligently, and the control of devices such as lights and air conditioners no longer completely depends on the radar signal. This enables the system to have the ability of self-learning and adjustment, reducing the influence of external interference (such as curtain or object movement) on the radar signal.

[0057] Any behavior of the guests in the room, such as sleeping or staying stationary for a long time, will not easily trigger the power off, thus ensuring the normal operation of electrical appliances, improving the check-in experience, and reducing unnecessary disturbances and dissatisfaction.

[0058] This invention is applicable not only to conventional situations but also to special situations (such as guests staying stationary for a long time or environmental interference) in the hotel environment, increasing the robustness of the system and being applicable to different types of rooms and check-in situations.

[0059] The technical innovation of this embodiment not only improves the intelligence of the automatic cardless power supply system, but also significantly improves the hotel management efficiency, reduces the complaint rate, and improves the comfort and satisfaction of the guests.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
