Description

Occupancy determination method and system, and room management system using the same {OCCUPANCY DETECTION METHOD AND SYSTEM, AND OCCUPANCY CONTROL SYSTEM USING THE SAME}

The present invention relates to a method and system for determining occupancy, and a room management system using the same, and more particularly, to a method and system for determining occupancy without a separate occupancy sensor, and a room management system using the same will be.

Conventionally, in a lodging facility having a plurality of rooms, when a guest returns a key, security key, etc., it is possible to recognize whether a guest is present. Accordingly, even when the guest is absent, the energy in the room is used as it is, making it difficult to save energy, and it is difficult to perform management tasks that should be performed when the guest is absent.

In order to solve this problem, an occupancy determination system has been proposed that installs a sensor in the room to determine whether a guest is occupant. However, according to this, it is necessary to install a sensor in each room, which is costly and time-consuming, and depending on the type of sensor, there may be problems such as an error in occupancy determination or exposure of guests' privacy.

As an example, a system for determining whether an occupancy is present using a carbon dioxide sensor and a human body sensor has been proposed as in Korean Patent Application Laid-Open No. 10-2018-0114728. However, since the carbon dioxide sensor determines that carbon dioxide generation not caused by human breathing is also caused by human breathing, the accuracy of occupancy determination may be reduced. In addition, the accuracy of occupancy determination may be reduced due to space and environment. For example, if the door of the room is kept open, even if the guest is in the room, the carbon dioxide concentration does not increase, so the determination of occupancy may not be made accurately. If the room has a large space, the carbon dioxide concentration may not be detected properly. It may not be. In addition, human body detection sensors such as passive infrared (PIR) sensors may have different accuracy of occupancy determination depending on the location and number of sensors, so it may detect that there is no person or may not detect it even when there is a person. In addition, if the guest does not move for a long time, it can be determined that there is no guest even when the guest is in the room.

In addition, since the existing occupancy determination system can simply determine whether a guest is occupant, it is difficult to utilize the guest occupancy information in various ways.

Referring to FIGS. 1 and 2 , the occupancy determination system 110 according to the present embodiment generates occupancy information by determining whether occupancy is occupancy using the power amount of the guest room 200 . More specifically, the occupancy determination system 110 includes a receiver 10 that receives watt-hour information from a watt-hour meter 210 installed in the guest room 200, and an analysis unit that determines whether occupancy is based on the watt-hour information and generates occupancy information ( 20) and a transmitter 30 for transmitting occupancy information. This occupancy determination system 110 is provided inside the guest room management system 100 including the room management server 40, the room control unit 50, the display unit 60, and the like, and can be used for energy saving of the guest room 200, etc. have. This will be described in more detail.

In the present embodiment, at least one watt-hour meter 210 is provided in each guest room 200 to measure the amount of power in each guest room. For example, the watt-hour meter 210 may be located in a control box 212 provided in each guest room 200, and may be located connected to wiring, wires, control units, etc. located inside the distribution panel 212. have. Then, the watt-hour meter 210 may be provided in each guest room 200 while not disturbing the guest's use of the guest room 200 and maintaining the guest room 200 in a comfortable state.

As the watt-hour meter 210, various known structures and methods may be applied. More specifically, the watt-hour meter 210 may have various structures and methods such as a mechanical watt-hour meter and an electronic watt-hour meter.

However, the present invention is not limited thereto. Therefore, the location, number, electrical connection structure, type, structure, method, etc. of the watt-hour meter 210 may be variously modified.

2 illustrates an example of various electronic devices 220 provided in the guest room 200 to which the occupancy determination system 110 according to the present embodiment is applied. As an example, the electronic device 220 in the guest room 200 includes a heating device 222 , a cooling device 224 , a light 226 , a television 228 , a coffee pot 230 , a stand 232 , and a hair dryer ( 234) was exemplified. However, the electronic device 220 of FIG. 2 is presented as an example for explaining the occupancy determination system 110 according to the present embodiment, and the present invention is not limited to the guest room shown in FIG. 2 . In FIG. 2 , the heating device 222 and the cooling device 224 are illustrated as being separately provided in each guest room 200 , but in reality, one device capable of heating and cooling may be provided, or installed in a building. Various modifications such as heating or cooling are collectively or individually controlled by an air conditioner or the like are possible.

The receiver 10 may receive the amount of power from the power meter 210 , generate power amount information, and provide it to the analyzer 20 . The receiver 10 may receive the amount of power from the power meter 210 by wire, or may be provided with one or more communication modules to be wirelessly connected to the power meter 210 to receive the amount of power.

More specifically, in the present embodiment, the receiving unit 10 may include a preprocessing unit 12 and a storage unit 14 .

The pre-processing unit 12 may receive the amount of power from the power meter 210 and perform pre-processing such as extracting information necessary for determining whether occupancy is present, removing an unnecessary part, or converting it into a desired form. Accordingly, real-time power amount information may be generated. Here, the real-time watt-hour information may mean watt-hour information corresponding to a specific time among continuously provided watt-hour information, and is a relatively short period of time (eg, within 1 minute, for example, within 5 seconds). It may mean information on the amount of power measured and provided at intervals.

The real-time power amount information generated by the pre-processing unit 12 may be provided to the analysis unit 20 as power amount information and used to determine whether occupancy is present. As an example, the waveform analyzer 22 of the analyzer 20 may determine whether occupancy is present using the real-time power amount information. The determination of whether the waveform analyzer 22 of the analyzer 20 is present using the electric energy information (more specifically, real-time electric energy information) will be described later in more detail.

In addition, the real-time power amount information generated by the preprocessor 12 is stored in the storage unit 14 , and the real-time power amount information stored in the storage unit 14 may constitute a power amount pattern having a predetermined pattern. Real-time wattage information or wattage information composed of wattage patterns may be provided to the analysis unit 20 at regular intervals and used to determine occupancy. As an example, the pattern analysis unit 24 or the deep learning unit 26 of the analysis unit 20 determines whether or not the occupancy is present by using the wattage pattern provided from the storage unit 14 and/or the wattage information composed of real-time wattage information. can Determination of whether the pattern analysis unit 24 or the deep learning unit 26 of the analysis unit 20 using the amount of power information provided from the storage unit 14 is occupancy will be described in more detail later.

The pre-processing unit 12 may classify power amount information for each guest room 200 and provide it to the storage unit 140 and/or the analysis unit 20 , and the storage unit 14 may provide power amount information for each guest room 200 . Alternatively, the wattage pattern may be classified and provided to the analysis unit 20 .

Various structures and methods may be applied to the pre-processing unit 12 , the storage unit 14 , and the like. For example, as the storage unit 14, various storage devices such as ROM, RAM, EPROM, flash drive, and hard drive may be used as hardware. Various other variations are possible.

The analysis unit 20 generates occupancy information including occupancy by determining occupancy by using the watt-hour information or watt-hour pattern received from the receiving unit 10 . In the present embodiment, the analysis unit 20 may determine whether to occupancy by using the amount of power information in various ways. For example, the analysis unit 20 uses active power, reactive power, instantaneous power amount, power amount information or pattern for a certain time, previous energy amount information or pattern, energy amount information or pattern of other rooms, etc. to determine whether to occupancy. can

In the present embodiment, the analysis unit 20 may include a waveform analysis unit 22 that analyzes and uses the waveform of the real-time power amount information to determine whether occupancy is present.

For example, the preprocessor 12 may extract an instantaneous active power amount from the amount of power received from the power meter 210 , generate real-time power amount information therefrom, and transmit it to the waveform analyzer 22 . Then, when the occupancy waveform including the waveform in which the instantaneous effective power amount or real-time power amount information changes to a certain level or more within a short time occurs due to the operation of the guest, the waveform analysis unit 22 can determine that the guest is occupant. have.

Here, as the operation of the guest generating a waveform in which the instantaneous active power amount or real-time power amount information changes to a certain level or more, an operation of turning on or off the electronic device 220 is mainly mentioned. For example, the operation of turning on or off the heating device 222 or the cooling device 224 , the operation of turning the light 226 on or off, the operation of the guest turning on or off the television 228 or a set-top box connected thereto, a coffee pot When the operation of turning on or using the 230, the operation of turning on the stand 232, the operation of turning on or using the hair dryer 234, etc., the instantaneous active wattage or real-time wattage information abruptly changes within a short time to change the occupancy waveform As this occurs, it can be judged that the guest is occupant.

At this time, since the various electronic devices 220 located in the guest room have different waveforms, when the occupancy waveform having a waveform in which the instantaneous effective power amount or real-time power amount information is rapidly changed, the guest can determine which electronic device among the various electronic devices 220 . It is known whether the device 220 is being used. For example, as shown in FIG. 3A , when the electronic device 220 that uses high power consumption for a short period of time, such as a coffee pot 232 , is used, the occupancy waveform may appear narrow and high. And, as shown in FIG. 3B , when the electronic device 220 that uses low power consumption for a relatively long time, such as the stand 232 , is used, the occupancy waveform may appear relatively wide and low. In addition, the amount of power may appear in stages according to the brightness of the light emitted from the stand 232 . Accordingly, the waveform analyzer 22 may further generate electronic device usage information by determining the occupancy waveform and analyzing the type, number of times of use, frequency of use, usage time, etc. of the electronic device 220 used.

As described above, the waveform analysis unit 22 detects an occupancy waveform including a waveform in which the instantaneous active power amount or real-time power amount information changes rapidly to determine the occupancy of the guest, so the accuracy of the guest's occupancy is very high. Also, it is possible to generate information on the use of the guest's electronic device based on the waveform. That is, the occupancy information may include not only occupancy information for determining occupancy of the guest, but also electronic device usage information, so that the occupancy information may be utilized more diversely.

In addition, in the present embodiment, the analysis unit 20 may include a pattern analysis unit 24 for determining whether occupancy by analyzing the generated wattage pattern using the wattage information for a certain period of time.

For example, the real-time power amount information generated by the preprocessor 12 is stored in the storage unit 14 for a certain period of time. At this time, the storage unit 14 provides the wattage information for a certain period periodically or in real time to the pattern analyzer 24, and the pattern analyzer 24 can generate an wattage pattern from the wattage information for a certain period. have. Alternatively, the storage unit 14 may generate an wattage pattern from wattage information for a certain period and provide it to the pattern analyzer 24 .

The plurality of vacancy patterns (vacancy patterns) and the plurality of occupancy patterns (occupancy patterns) are preset or stored in the pattern analysis unit 24 or the storage unit 14 and are stored in the pattern analysis unit 24. It can be used when analyzing wattage patterns. The wattage pattern of the plurality of vacant states and the wattage pattern of the plurality of occupancy states may initially be preset or stored in the pattern analysis unit 24 or the storage unit 14, and the amount of electricity generated by the deep learning unit 26 Patterns can be updated as they accumulate. Accordingly, it is possible to further improve the accuracy of occupancy determination of the pattern analysis unit 24 using the wattage pattern.

The pattern analysis unit 24 compares the wattage pattern of the corresponding guest room 200 with the wattage pattern of the vacant state or the wattage pattern of the occupancy state to determine whether occupancy is present.

More specifically, the storage unit 14 or the pattern analysis unit 24 divides the amount of power information for a certain period into unit cycles, extracts statistical values corresponding to the unit cycle, and sequentially lists them to generate a power amount pattern. As an example, as shown in (a) of FIG. 4 , a wattage pattern may be formed by extracting statistical values of wattage at a unit cycle of 1 minute and arranging them sequentially for a predetermined period of 30 minutes. The pattern analysis unit 24 compares the wattage pattern of the corresponding guest room 200 with the wattage pattern in the vacant state or the wattage pattern in the occupancy state to find the most similar wattage pattern (the most similar pattern). In addition, as shown in FIG. 4B , if the most similar pattern to the wattage pattern of the corresponding guest room 200 corresponds to the wattage pattern of the occupancy state, it may be determined as the occupancy state. Conversely, if the most similar pattern to the wattage pattern of the corresponding guest room 200 corresponds to the wattage pattern of the vacant state, it may be determined as the vacant state.

Here, when the pattern analyzer 24 compares the wattage pattern with the wattage pattern of the vacant state or the wattage pattern of the occupancy state, the occupancy may be determined in consideration of the season, day of the week, time, etc. That is, when the pattern analysis unit 24 compares the wattage pattern with the wattage pattern in the vacant state or the wattage pattern in the occupancy state, the wattage pattern at the same, similar, or overlapping time in consideration of the season, day of the week, time, etc. It can be used as a comparison object. For example, as shown in FIG. 4 , when the pattern of the wattage is received from 9:00 to 9:30, the pattern analysis unit 24 determines the wattage pattern of the occupancy state and the wattage pattern of the vacancy state corresponding to the morning time. can be compared to find the most similar pattern. Accordingly, the accuracy of occupancy determination by the pattern analysis unit 24 can be further improved.

4 exemplifies the generation of the wattage pattern according to the unit period in the form of a graph, but the present invention is not limited thereto, and the wattage pattern may be generated in various forms such as numbers and characters.

In addition, the analysis unit 20 may include a deep learning unit 26 that determines whether occupancy by using deep learning. For example, the deep learning unit 26 compares and analyzes the electric energy information or pattern of the corresponding room 200 using artificial intelligence and the electric energy information or pattern of the previous room or other rooms to determine whether to occupancy. have. Alternatively, the deep learning unit 26 builds an occupancy prediction model that can predict the vacancy or occupancy state based on a plurality of wattage information or patterns provided from the storage unit 14 or the pattern analysis unit 24, It can be determined by predicting the vacancy state or the occupancy state through the occupancy prediction model.

And when the deep learning unit 26 determines the vacancy state or the occupancy state according to the electric energy information or pattern of the corresponding guest room 200, the electric energy information or pattern (ie, the learned pattern) of the corresponding guest room 200 is analyzed as a pattern It can be provided to the unit 24 or the storage unit 14 to improve the accuracy of occupancy determination by diversifying the strategy information or patterns of the pattern analysis unit 24 or the storage unit 14 .

The deep learning unit 26 may include various hardware resources and/or software capable of determining the vacancy state or the occupancy state according to the wattage information or pattern. As the deep learning model used by the deep learning unit 26, various models may be used, for example, a deep neural network (DNN), a convolutional neural network (CNN), a recurrent neural network (recurrent). A neural network (RNN), a restricted Boltzmann machine (RBM), a deep belief network (DBN), a deep Q-networs, and the like may be used.

The deep learning unit 26 may be provided to independently determine whether occupancy is present, but may be provided together with the waveform analysis unit 22 and the pattern analysis unit 24 to complement them.

The analysis unit 20 according to the present embodiment may determine whether an occupancy is present by using the waveform analysis unit 22 , the pattern analysis unit 24 , and the deep learning unit 26 in combination. That is, the waveform analyzer 22 may continuously receive real-time power amount information and, when a waveform that can be determined as the occupancy state is found, may determine the occupancy state. In this case, the waveform analyzer 22 may generate electronic device usage information such as the number of times, frequency of use, and usage time of the electronic device 220 used by the guest as part of the occupancy information through waveform analysis. In addition, the pattern analysis unit 24 may determine the vacancy state or the occupancy state in real time or at a predetermined period by using the wattage pattern for a predetermined period. In addition, the deep learning unit 26 may determine the vacancy state or the occupancy state in real time or in a predetermined period.

When it is determined that the guest is occupant by the waveform analyzer 22 , the pattern analyzer 24 , or the deep learning unit 26 , the occupancy state may be determined. And when it is determined that the guest is absent by the waveform analysis unit 22 , the pattern analysis unit 24 , or the deep learning unit 26 , it may be determined as a vacant state. If the occupancy or absence of the guest is not accurate, the occupancy state is determined once, and the determination by the waveform analysis unit 22, the pattern analysis unit 24, or the deep learning unit 26 is continuously performed to indicate that the guest is absent. If judged, it may be determined as vacant at that time. If the analysis unit 20 determines that the guest room 200 is vacant, the guest room 200 may be controlled in an energy saving mode, etc. by the room control unit 50, etc., which may cause inconvenience to the guest if the guest is in the occupancy state. Because. In this way, when the analysis unit 20 clearly confirms the absence of the guest, it is determined as the vacant state, thereby minimizing the inconvenience of the guest.

As described above, the occupancy information generated by the analysis unit 20 includes not only occupancy information, but also the number of times, frequency of use, and usage of the electronic device 220 used by the guest among various electronic devices 220 provided in the guest room 200 . Electronic device usage information such as time may be included. As described above, occupancy information including occupancy status and electronic device usage information may be utilized for various services.

The transmitter 30 may transmit the occupancy information generated by the analyzer 20 to the outside. The transmitter 30 may transmit occupancy information to the outside by wire, or may include one or more communication modules to be wirelessly connected to the outside to transmit occupancy information. Here, the transmitter 30 may transmit the occupancy information to various places and servers utilizing occupancy information.

As an example, the transmitter 30 may transmit the occupancy information generated by the analysis unit 20 to the room management server 40 or a hotel server system that manages a room by using the occupancy information.

The guest room management server 40 may classify the occupancy information of the plurality of guest rooms 200 provided from the transmitter 30 for each room and perform management, storage, deletion, change, and the like. In this case, the guest room management server 40 may classify occupancy information for each room and electronic device usage information upon occupancy to manage, store, delete, change, and the like. In addition, the room management server 40 may generate a room control signal by using room information including room availability information and/or electronic device usage information.

In addition, the room management server 40 may provide a room control signal to the room control unit 50 to manage and control the room. More specifically, the room control unit 50 may receive the occupancy control signal provided from the room management server 40 and control the various electronic devices 220 according to the reception control signal.

More specifically, in the case of a vacant state, the room management server 40 may generate an energy saving control signal and provide it to the room control unit 50 . Then, the cabin controller 40 may perform energy saving control on the cabin 200 . For example, in the energy saving control, the room controller 50 turns off the power of the electronic device 220 in the guest room 200 or turns off the power of the electronic device 220 in the guest room 200 according to preset room control data (indoor temperature, on/off of lights, heating/cooling operation), etc. The electronic device 220 in 200 may be operated under a desired condition.

For example, in the energy saving mode, the room controller 50 turns off the heating device 222 , operates the heating device 222 at a temperature lower than the temperature set by the guest, or operates the heating device 222 at a predetermined interval. It can be operated to save energy. Alternatively, in the energy saving mode, the room control unit 50 turns off the air conditioner 224, operates the air conditioner 224 at a temperature higher than the temperature set by the guest, or the air conditioner 224 operates at regular intervals. It can be operated to save energy. Alternatively, in the energy saving mode, the cabin control unit 50 turns off the power of the light 226 , the television 228 , the coffee pot 230 , the stand 232 , or the like, or the brightness of the light 226 or the stand 232 . can be reduced to save energy.

On the other hand, in the occupancy state, the room management server 40 may generate an occupancy signal and provide it to the room control unit 50 to perform the occupancy mode. In the occupancy mode, the guest room controller 50 does not separately control the guest room 200 so that the guest can use the guest room 200 as desired.

For example, the room control unit 50 may be a control unit (eg, a room control unit) provided in the guest room 200 . However, the present invention is not limited thereto, and various modifications such as the guest room control unit 50 being provided in addition to the guest room 200 or provided in the guest room management server 40 or the hotel server system are possible.

As the audio output unit used in the display unit 60 , various sound devices that provide occupancy information to the user through sound, music, sound, etc. may be used. Various other variations are possible.

Then, the manager who manages the guest room 200 may provide services necessary for the occupancy or vacancy of the guest by utilizing the occupancy information (in particular, occupancy information) displayed on the display unit 60 . Also, it is possible to visualize a guest's energy use pattern, etc. by occupancy information (especially, electronic device usage information), so that the guest's satisfaction can be improved by using it for hotel management.

For example, when it is desired to provide necessary items, meals, notification service, etc. according to the guest's request, the manager may contact or visit the guest while staying in the room to provide the service to the guest.
