[0036] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0037] It should be noted that the flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor do they have to be executed in the order described. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0038] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0039] Some embodiments of the present invention disclose a method for taking power and disconnecting power, which is applied to a door lock. The door lock has a radio frequency transmitter and an infrared sensor located in the room. The infrared sensor is used to detect whether there is someone in the room by receiving infrared radiation emitted by the human body and converting it into an electrical signal. By integrating the radio frequency transmitter and the infrared sensor in the door lock, the difficulty of deployment and the cost of modification can be greatly reduced in the intelligent modification of the hotel. It should be noted that the infrared sensor is not separately arranged in the room, but is an integrated structure with the door lock.

[0040] like Figure 1 As shown, the power-on and power-off method comprises the following steps:

[0041] When the door is unlocked, the radio frequency transmitter and infrared sensor are awakened;

[0042] Sending a first power-drawing signal to the power-drawing switch through a radio frequency transmitter, wherein the first power-drawing signal is used for the power-drawing switch to temporarily draw power;

[0043] Determine whether the infrared sensor has a signal. If so, send a second power-on signal to the power switch through the RF transmitter, and the second power-on signal is used for the power switch to keep drawing power; if not, send a power-off signal to the power switch through the RF transmitter, and the power-off signal is used for the power switch to stop drawing power.

[0044] The power supply and power-off method can realize intelligent and automatic power supply and power-off control, and enhance the sense-free experience of the occupants.

[0045] In some embodiments, a power-off signal is sent to the power switch via a radio frequency transmitter, and then the method further includes:

[0046] After detecting that the door is locked, the radio frequency transmitter and the infrared sensor are controlled to resume the dormant state.

[0047] For example, when the occupant wants to enter the room and unlock the door, the RF transmitter and infrared sensor will be awakened, and then the RF transmitter will send a first power-drawing signal to the power switch. At this time, the power switch will temporarily draw power to temporarily power the equipment in the room (such as lights, televisions, etc.). If the occupant enters the room, the infrared sensor will have a signal, and the RF transmitter will send a second power-drawing signal to the power switch, and the power switch will continue to draw power. If the occupant does not enter the room after unlocking the door, the infrared sensor will not have a signal, and the RF transmitter will send a power-off signal to the power switch. The power switch will stop drawing power and stop supplying power to the equipment in the room. At this time, the occupant may close the door (i.e. lock the door) before entering the room, or the subsequent staff will close the door. At this time, the RF transmitter and infrared sensor will enter a dormant state and wait to be awakened again.

[0048] In some embodiments, the power-off signal can be used to stop the power supply after the power switch has been delayed for a first preset period of time. That is, if the occupant does not enter the room after the lock is unlocked, the power supply in the room will be disconnected after the first preset period of time. For example, the first preset period of time is 5 minutes, and the 5 minutes here is only an example and is not intended to limit the present application. It can also be other.

[0049] In some embodiments, when the door lock is detected, the radio frequency transmitter and the infrared sensor are awakened, including: when the door lock request is received and the recognition is successful, the unlocking is triggered, and the radio frequency transmitter and the infrared sensor are awakened. For example, the occupant can input the door lock request by swiping the room card, entering the password, scanning the code, face recognition, etc. When the door lock is successfully recognized, the unlocking is triggered, thereby waking up the radio frequency transmitter and the infrared sensor.

[0050] In some embodiments, the first power-taking signal is used to temporarily power the power switch for a second preset time period. That is, when the occupant enters the room and unlocks the door, the equipment in the room will be temporarily powered for a second preset time period. For example, the second preset time period is 10 minutes, etc. The 10 minutes here is only an example and is not intended to limit the present application. It can also be other.

[0051] In some embodiments, determining whether the infrared sensor has a signal, if so, sending a second power-on signal to the power switch through a radio frequency transmitter; if not, sending a power-off signal to the power switch through a radio frequency transmitter, includes:

[0052] Determine whether the lock is detected and whether the infrared sensor has a signal. If both are yes, send a second power-off signal to the power switch through the radio frequency transmitter; if either is no, send a power-off signal to the power switch through the radio frequency transmitter.

[0053] For example, if the occupant enters the room and closes the door (i.e., locks it), the infrared sensor will have a signal, the RF transmitter will send a second power-on signal to the power switch, and the power switch will continue to draw power. If the occupant does not enter the room and close the door, the infrared sensor will not have a signal, the RF transmitter will send a power-off signal to the power switch, and the power switch will stop drawing power. If the occupant enters the room but does not close the door, even if the infrared sensor has a signal, the RF transmitter will send a power-off signal to the power switch, and the power switch will stop drawing power. By determining whether the lock is detected and whether the infrared sensor has a signal, the accuracy of the judgment of the person's check-in is ensured, and the accuracy of the judgment of continuous power drawing is ensured.

[0054] In some embodiments, such as Figure 2 As shown, you can first determine whether the lock is detected, and then determine whether the infrared sensor has a signal, as follows:

[0055] Determine whether the lock is detected. If not, send a power-off signal to the power switch through the radio frequency transmitter; if so, determine whether the infrared sensor has a signal. If not, send a power-off signal to the power switch through the radio frequency transmitter; if so, send a second power-on signal to the power switch through the radio frequency transmitter.

[0056] In some other embodiments, Figure 3 As shown, you can also first determine whether the infrared sensor has a signal, and then determine whether the lock is detected, as follows:

[0057] Determine whether the infrared sensor has a signal. If not, send a power-off signal to the power switch through the radio frequency transmitter; if so, determine whether the lock is detected. If not, send a power-off signal to the power switch through the radio frequency transmitter; if so, send a second power-on signal to the power switch through the radio frequency transmitter.

[0058] In some embodiments, such as Figure 4 As shown, the second power-taking signal is sent to the power-taking switch through the radio frequency transmitter, and then the infrared sensor is controlled to be in a working state, and the radio frequency transmitter is controlled to be in a dormant state. The infrared sensor is in a working state to prepare for automatic power off when the occupants leave, and the infrared sensor is low power consumption.

[0059] In some embodiments, such as Figure 4 As shown, the power-on and power-off method also includes:

[0060] When the infrared sensor is in working state, it is determined that unlocking is detected and when it is determined that the infrared sensor has a signal, the radio frequency transmitter is awakened.

[0061] For example, the infrared sensor being in working state means that someone has moved into the room. When the occupant unlocks the room, the infrared sensor will inevitably generate a signal. By detecting the unlocking and determining that the infrared sensor has a signal, it can be determined that the occupant has a tendency or intention to go out.

[0062] In some embodiments, such as Figure 4 As shown, the RF transmitter is woken up, and then:

[0063] When the lock is detected and the infrared sensor has no signal, a power-off signal is sent to the power switch through the radio frequency transmitter. Specifically, by detecting the lock and judging that the infrared sensor has no signal, it can be judged that the occupant has locked and left, and then the automatic power off can be controlled.

[0064] In some embodiments, such as Figure 4 As shown, the RF transmitter is woken up, and then:

[0065] When it is determined that the lock is locked and the infrared sensor has a signal, the radio frequency transmitter is controlled to resume the dormant state. Specifically, by determining that the lock is locked and the infrared sensor has a signal, it can be determined that the occupant has locked the room but has not left the room, for example, the occupant has left the room to look around and then returned to the room. Then, the radio frequency transmitter can be controlled to resume the dormant state and wait for the occupant to unlock the room and leave the room next time.

[0066] Specifically, Figure 4 As shown, it is determined whether the lock is detected. If not, the power is continued to be drawn; if so, it is determined whether the infrared sensor has a signal. If not, a power-off signal is sent to the power switch through the radio frequency transmitter; if so, the power is continued to be drawn and the radio frequency transmitter is controlled to resume the sleep state.

[0067] like Figure 5 As shown, some embodiments of the present invention further disclose a door lock, including a radio frequency transmitter, an infrared sensor and a processor. The door lock also includes a main structure installed on the door, and the radio frequency transmitter, the infrared sensor and the processor are all integrated on the main structure.

[0068] The radio frequency transmitter is used to transmit radio frequency signals. The infrared sensor is located in the room, and the infrared sensor is used to detect whether there is someone in the room by receiving infrared radiation emitted by the human body and converting it into an electrical signal. The processor is used to implement the power-on and power-off method described in any of the above embodiments, which will not be repeated here. For example, the processor is a single-chip microcomputer, and the single-chip microcomputer here is only an example and is not intended to limit the present application. It can also be other.

[0069] By implementing the present invention, the following beneficial effects are achieved:

[0070] The present invention integrates a radio frequency transmitter and an infrared sensor located in the room in the door lock, thereby greatly reducing the difficulty of deployment and modification costs in the intelligent modification of the hotel. In addition, when the door unlocking is detected, the radio frequency transmitter and the infrared sensor are awakened, and then a first power supply signal is sent to the power supply switch through the radio frequency transmitter. The first power supply signal is used for the power supply switch to temporarily supply power. Finally, it is determined whether the infrared sensor has a signal. If so, a second power supply signal is sent to the power supply switch through the radio frequency transmitter. The second power supply signal is used for the power supply switch to maintain power supply; if not, a power-off signal is sent to the power supply switch through the radio frequency transmitter. The power-off signal is used for the power supply switch to stop supplying power. The power supply and power-off method can realize intelligent and automated power supply and power-off control, and enhance the senseless experience of the guests.

[0071] It is understandable that the above embodiments only express some implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above embodiments or technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present invention, that is, the embodiments described in "some embodiments" can be freely combined with any of the above and below embodiments.
