Description

Technical Field

[0001] The present invention relates to the field of smart homes, and in particular to a hotel power supply control system and method. Background Art

[0002] With the popularity of mobile phones and other Bluetooth terminals in hotel door opening, more and more hotels no longer use room cards as the medium for door opening. Instead, the user is given unlocking authority, such as authorization to the corresponding app installed by the user. After the user has the above authority, he can use a mobile phone or other Bluetooth terminal to unlock the door, or the user is issued an unlocking password, which completely abandons the use of room cards in the past.

[0003] Due to the changes in the above-mentioned door opening / unlocking methods, the room card used as a judgment medium for hotel power supply is no longer used. As a result, without the room card, it is impossible to accurately judge whether the room is occupied or not, and it is impossible to cut off the power circuit in time when no one is in the room, resulting in a waste of electricity.

[0004] Therefore, a new hotel power supply control system and method are needed, which mainly solves the problem of automatically cutting off the power when no one is in the room, thereby saving electricity costs. Summary of the invention

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0055] In the description of the present invention, it is necessary to understand that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0057] In the following description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module" and "component" can be used interchangeably.

[0058] See also Figure 1, which is a schematic diagram of the system architecture of a hotel power supply control system in a preferred embodiment of the present invention. In this embodiment, the hotel power supply control system is built in units of rooms, that is, the control object of each power supply control system in the hotel is a room or suite, etc., and the unit needs to use the same power supply mode. Therefore, the hotel power supply control system is applied to any room. In order to supply power to the electrical appliances in the room or suite, the hotel power supply control system includes a power supply, which can be drawn from the hotel bus and introduced into each room respectively. In order to conditionally control the power supply of the power supply, the hotel power supply control system also includes a switch module, which is connected to the power supply, and the control of the switch module can turn on or off the power supply circuit from the power supply to the electrical appliances.

[0059] In addition, the hotel power supply control system also includes a wireless communication module and a smart door lock. The wireless communication module, such as a Wifi module, is fixedly installed in the room, such as on the roof or in an inconspicuous place in the room, and is used to establish a wireless network for wireless Internet access in the room. The wireless communication module includes a first communication unit. In this embodiment, the switch module will be connected to the wireless network. Therefore, the switch module includes a second communication unit that can be used for external communication connection. The first communication unit and the second communication unit are connected in communication so that the switch module can receive data from other access devices from the wireless network, and send its own data to the wireless network for other access devices to obtain. The smart door lock is installed at the door of the room. According to the needs of the user, it can be unlocked outside the door to enter the room, or unlocked in the room to enter the outside of the room. In this embodiment, the smart door lock contains a third communication unit, and the third communication unit can be used to connect the smart door lock to the wireless network. That is, after the third communication unit is connected to the first communication unit, the unlocking, unlocking, and doorbell status of the smart door lock can be sent to the wireless communication module. At the same time, the third communication unit will broadcast the door lock status signal to the outside, so that even if the device is not connected to the wireless network, it can receive the door lock status signal of the smart door lock.

[0060] Since the card-insertion power supply method of the room has been cancelled, the original method of starting the power supply circuit of the power supply source needs to be re-established. Therefore, the switch module can be partially exposed and installed at the door of the room, and presented to the user in a pressable and touchable form. When the user enters the room, the user can be reminded to press or touch the switch module to trigger the switch module (for example, the switch module is a button, and the user presses the button, which is regarded as triggering the switch module). The switch module has a preset time length built in. Once triggered, the power supply circuit for the power supply source to supply power to the room will be turned on, and the conduction time is the preset time length. In other words, after the user presses the button, the room will be powered within a certain period of time, but after the preset time length ends, the room will be powered off to save energy. Further, in order to meet the user's continuous power supply needs in the room, the following mechanism will be adopted, that is, considering that the user is usually used to connect the terminal carried by himself, such as a mobile phone or a tablet computer, to the wireless communication module in the room when staying in the room. Therefore, it can be determined whether the user is still in the room according to the connection status between the terminal and the wireless communication module, so as to further determine whether the room needs to continue to be powered. Specifically, once the wireless communication module receives a connection request from at least one terminal and establishes a wireless connection with the terminal so that the terminal can access the Internet normally, the wireless communication module will actively send a maintenance instruction to the second communication unit of the switch module through the first communication unit. The switch module can know that the user is continuously in the room and the power should not be cut off. Therefore, based on the reception of the maintenance instruction, the switch module cancels the preset time limit and can continuously turn on the power supply circuit.

[0061] Therefore, through the user's regular and usual actions, it can be intelligently determined whether the power supply needs to be cut off, which can save electricity on the one hand and ensure the user's normal electricity demand on the other.

[0062] Preferably, in order to prevent the power supply circuit from being turned on without restriction, resulting in a waste of electric energy, a mechanism for shutting down the power supply circuit is provided in a preferred embodiment. Specifically, when the smart door lock triggers an unlocking and locking operation, it indicates that someone may leave the room, or someone may enter the room, or the user may open the door to take items. In the above situation, when the person leaves the room, the power supply circuit should be cut off. Therefore, after the above operation occurs, the smart door lock will add a switch status bit to the door lock status signal broadcast to the outside after triggering an unlocking and locking operation, indicating that one of the above situations has occurred in the smart door lock. After receiving the above door lock status signal and reading the switch status bit, the switch module receives the occurrence of the above situation. In response, the switch module will disconnect the power supply circuit that supplies power to the room from the power supply source.

[0063] As described above, since all three situations will result in unlocking and locking operations, and the result of disconnecting the power supply circuit is preferably applicable to the situation where a person leaves the room, if the power supply circuit is disconnected in the other two situations, it can be understood that the user can trigger the switch module again to obtain power.

[0064] In addition, in a preferred embodiment, in order to completely avoid misidentification or the inconvenience of the user operating the switch module multiple times, the above operation situation will be identified. Specifically, the smart door lock includes a door lock unit, an identification module and an operation module. The door lock unit is used to mechanically close or open the smart door lock to control the switch state of the smart door lock. The identification module can be set at a position where the smart door lock faces the outside of the room, and can be in the form of a fingerprint recognition area of ​​a fingerprint lock. When a user outside the room needs to enter the room, the user's operation on the identification module (such as fingerprint recognition, or taking an unlocking unit such as a Bluetooth key to match the identification module) will be regarded as the user's operation on the identification module from the outside. After the identification module recognizes the operation of the unlocking unit, it will send an unlocking instruction to the door lock unit, so that the door lock unit is unlocked, which is recorded as an external opening operation. The operation module can be set at a position where the smart door lock faces the inside of the room, and can be in the form of a rotary lock. When a user inside the room needs to enter the outside of the room, the user's operation on the operation module (such as the user rotates the rotary lock) will be regarded as the user's operation on the operation module from the inside, and the operation module drives the door lock unit to unlock, which is recorded as an internal opening operation. By distinguishing the above two operations, when the smart door lock triggers an external unlocking and locking operation, an external opening state bit is added to the door lock state signal. On the other hand, if the smart door lock triggers an internal unlocking and locking operation, an internal opening state bit is added to the door lock state signal. Due to the distinction between the two types of state bits, the switch module is configured to disconnect the power supply circuit from the power supply source to the room only when and only when it receives the door lock state signal containing the internal opening state bit. In other words, if the user performs an external opening operation, the power supply circuit will not be disconnected, avoiding the control of accidental power failure.

[0065] To further avoid the situation described above where "the user opens the door to take items", the user does not actually leave, but the power supply circuit is still disconnected. Therefore, in a further embodiment, when the switch module receives the door lock state signal containing the inner opening state bit, it is first configured to maintain the power supply circuit for the room to be powered by the power supply source within a maintenance time, which can be 2 minutes to 5 minutes, that is, no matter what happens during this period of time, the power supply circuit will be maintained. At the same time, the switch module will retrieve the terminal list with established wireless connection from the wireless communication module. It can be understood that if the user performs the inner opening operation and actually leaves the room and the hotel, he will generally take the terminal with him. In this case, there should be no terminals that are connected in the terminal list; on the contrary, if the user performs the inner opening operation, but only takes items, such as express delivery or take-out, he generally does not take the terminal to leave. In this case, the previously connected terminals in the terminal list will not be removed, and there are still terminals that are connected in the terminal list. Therefore, the switch module is configured such that when the terminal list is empty, the switch module disconnects the power supply circuit that supplies power to the room; when the terminal list is not empty, the switch module maintains the power supply circuit that supplies power to the room, thereby being able to determine whether the user is in the room as intelligently as possible while demanding power conservation, so as to avoid accidental power outages.

[0066] On the other hand, if the user does not immediately connect to the wireless network of the room after entering the room (for example, some users are used to cleaning the room first, etc.), the above situation will also cause the power supply circuit to be disconnected. Therefore, in a preferred embodiment, the smart door lock will communicate with the wireless communication module; when the switch module is triggered, the wireless communication module will know the situation, and a preset time length is configured in the wireless communication module, and the preset time length starts from the time when the wireless communication module knows the switch module. If the wireless communication module does not receive a connection request from at least one terminal within the preset time length, the wireless communication module will inform the switch module, and the switch module will feedback the information by sending a reminder instruction to the wireless communication module; the wireless communication module forwards the reminder instruction to the smart door lock based on the reminder instruction, and the smart door lock sends a wireless connection reminder voice based on the reminder instruction. For the user, he can hear the wireless connection reminder voice in the room, put down what he is doing, and preferentially connect the terminal to the wireless communication module, so as to facilitate the subsequent control of the power supply circuit according to the connection status of the terminal.
