Description

Technical Field

[0001] The present invention relates to the fields of Internet of Things and energy conservation, and particularly to an energy conservation management system. Background Art

[0002] Traditionally, the energy conservation devices used in hotel rooms are usually card-taking power distributors installed at the door of the room. When a guest checks into the room, the guest inserts the room card into the card-taking power distributor to activate the power supply to the room, and when leaving the room, the guest pulls out the room card from the card-taking power distributor to deactivate the power supply to the room (i.e., cut off the power to the room), so as to achieve energy conservation when there is no one in the room. However, this technology has the following defects: First, when multiple people check in, if one person leaves the room card in the card-taking power distributor and uses the room cards of other people to enter and leave the room, the card-taking power distributor cannot play the role of energy conservation; Second, with the development of intelligent door lock technology, ways to enter the room without using a room card gradually emerge. For example, password unlocking and mobile phone unlocking replace the room card. After the room card disappears, the card-taking power distributor naturally cannot play the role of energy conservation. Summary of the Invention

[0003] An energy conservation management system according to an embodiment of the present invention is used to be deployed in a room unit including one or more rooms. The energy conservation management system includes: an entrance door detection unit configured to detect the opening or closing movement of the entrance door of the room unit, generate an entrance door movement signal when detecting the opening or closing movement of the entrance door, and send the entrance door movement signal to the power distributor; an in-room detection unit configured to detect the human movement in the room unit, generate a human movement signal when detecting the human movement in the room unit, and send the human movement signal to the power distributor; and a power distributor configured to determine whether there is someone in the room unit based on the entrance door movement signal and the human movement signal, and control the power supply or power cut-off to the room unit based on the determination result.

[0011] Figure 1 A schematic block diagram of an energy-saving management system according to an embodiment of the present invention for deployment in a room unit including one or more rooms is shown. As Figure 1As shown in the figure, the energy-saving management system 100 includes an entrance door detection unit 102, an in-room detection unit 104, and an electrical appliance extractor 106, where: The entrance door detection unit 102 is configured to detect the opening or closing movement of the entrance door of the room unit, generate an entrance door movement signal when detecting the opening or closing movement of the entrance door, and send the entrance door movement signal to the electrical appliance extractor 106; The in-room detection unit 104 is configured to detect the human movement in the room unit, generate a human movement signal when detecting the human movement in the room unit, and send the human movement signal to the electrical appliance extractor 106; The electrical appliance extractor 106 is configured to determine whether there is someone in the room unit based on the entrance door movement signal and the human movement signal, and control the power supply or power-off of the room unit based on the determination result.

[0017] It should be noted that when using Figure 3When the radar sensor 300 shown is used as the entrance door detection unit 102 and the in-room detection unit 104, the radar sensor used as the entrance door detection unit 102 can be set on the door frame of the entrance door. By setting the sensing distance of the radar sensor very close, the radar sensor can only sense the opening or closing movement of the entrance door, and will not be disturbed by the human body movement in the room unit; the radar sensor used as the in-room detection unit 104 can be set on the roof or wall inside the room unit, and multiple radar sensors can be set according to the spatial characteristics of the room unit, and by setting the sensing distance of each radar sensor, these radar sensors can fully sense the human body movement in the room unit.
