Description

TECHNICAL FIELD

The present invention relates to a system and a method for energy-saving air conditioning control via QR (Quick Response) code.

BACKGROUND

Smart air conditioning apparatuses were appeared on the market in about 2010, and until now there are many different manufacturers join to develop and manufacture the smart air conditioning apparatuses. The smart air conditioning apparatus may aim for several various purposes, such as energy-saving, enhancing the usability, increasing the comfort and user experiences, for example. It can be said that, the conventional smart air conditioning apparatus generally contributes for improving the quality of the air conditioning for users significantly.

However, by the observation of inventors, most of users use the smart air conditioning apparatus or a group of the smart air conditioning apparatuses have not yet fully exploited useful functions of them, while manufacturers may provide smart algorithms for integrating plurality of control modes according to various different purposes for the smart air conditioning apparatus, such as energy-saving mode, bedtime mode, etc., many users may not understand correctly or not use correctly the control modes when referring to their living habits or their actual demands. Some of users, during their use, often unchanged or be slow to change parameters or setting operation mode of the air conditioning apparatus in comparison with the time when they turn on, for example when turning on they may set the temperature very low and keep unchanged until feeling uncomfortable, for example feeling very cold before they perform a change, for example increasing the temperature and decreasing the fan speed.

In addition, the setting of the temperature is very low and the fan speed is very high when turning on the air conditioning apparatus may also happen at many public areas, may be at areas where the adjustment of the operation of the air conditioning apparatus not specifically assigned for anyone, even the operation situation may last while there is no one presented at the area where the air conditioning is employed, for example.

The smart air conditioning apparatuses are also said that they not change the operation mode according to the changes of the factors of surrounding environment or habits of the users.

Because the energy needed to use for the air conditioning, generally for all society is very huge, the energy-saving, or in particularly, the electricity-saving during the using of the air conditioning apparatuses have a very important meaning. Although the smart air conditioning apparatuses may solve a part of the problem of the energy-saving in an individual operation mode of them, the energy-saving in general terms such as an adequately adjustment corresponding to the surrounding environment, habits of users, when there are many air conditioning apparatuses commonly operate in a same space or in a same system, is supposedly that not solved very well.

As for that, there is a need of an air conditioning monitoring and control approach may solve the energy-saving problem or the energy-saving solution which is more overall and optimally.

Furthermore, the old generation air conditioning apparatuses are currently in use with a quite huge number. Due to the lifetime of the air conditioning apparatuses are relatively long, and when it is in a comparison with the development of the intelligent control technologies the lifetime of the air conditioning apparatuses may be said to be very long time. Therefore, as for the air conditioning apparatuses, even the “old generation” smart air conditioning apparatuses, upgrading them is very difficult.

Hence, there is also a need of an air conditioning monitoring and control approach may solve the energy-saving or electricity-saving problem, may be applicable supplemental equipped for existed air conditioning apparatuses, to be for using new control algorithms, for example intelligent control algorithms aimed to the energy-saving.

As for conditioning apparatuses are used at places that provides a public service for many people, such as at universities/schools, hospitals, restaurants/shops, or similar areas. Starting and running the conditioning apparatuses using handhold remote controls are usually separate, may lead to a repetition needed for a control operation for plurality of conditioning apparatuses so that it is possible to be used for an entire desired area. If the conditioning apparatuses are not from the same manufacturer, or from the same brand but there are different models, may lead to an inconvenience, for example due to a wrong choice of a handhold remote control or a confusion between different air conditioner brands. In addition, may easily be forgotten or lost, and difficulty in monitoring and assigning for who are authorized to control.

As for some lines of air conditioning apparatuses may be controlled via software applications, for example applications installed on smartphones.

Genuine air conditioning control applications have appeared, however, most of these applications are only developed with control sharing features for home use only, therefore it is substantially difficult or impossible in sharing control rights for employees to use to implement at places that provide a public service for many people.

Air conditioner control applications are developed by third parties often integrating many different models for users to select, the selection may be via different names or icons. However, for relatively large number, will cause problems for those who are not very familiar with technology, for example spending extra time or choose the wrong model.

Hence, there is also a need of a conditioning control approach implemented at places that provides a public service for many people, which is convenient to use and control for both users and administrator/manager.

DESCRIPTION OF EMBODIMENTS

Hereinafter, advantages, efficiencies, and inventive concepts of the present invention shall be understood more clearly through the detailed description of the preferred embodiments with reference to the accompanying drawings. In the drawings, same reference numbers are intended to indicate same or equivalent components or elements and commonly used in the whole description, therefore in several drawings or several parts of a drawings may not show one or more reference numbers for a purpose that makes the drawings becoming simplified and facilitating for showing composed components or different inventive concepts of the present invention, in this scenario, relationships between certain components or elements with corresponding reference numbers may be clearly illustrated when referring to other drawings or other components on the drawing. In addition, the components and elements illustrated in the drawings is not complied actual sizes and shapes, several components or elements shall be exaggerated and may be presented by simplified blocks for illustrated purposes and facilitating for descriptive purpose. Therefore, it should be understood that embodiments described herein is only exemplary for fully understanding of the inventive steps and advantages of the present invention, without any limitation of the present invention to the embodiments.

Herein, the air conditioning apparatus is basically a device with a function to maintain the room air at a stable setting temperature/expected temperature to provide an environment which is more comfortable for users, the temperature stabilization may be cooling down the air or heating the air. Several two-way air conditioning apparatuses generally include both air cooling function and air heating function, whereas several air conditioning apparatuses have only one function for cooling the air may be called as an air cooling device/air conditioner, or only one function for heating the air may be called as a heater.

Common features of the two-way air conditioning apparatus or conventional air conditioner may include two components which are a condenser unit and an evaporator unit, these two components may be arranged integrally in one package, may be called as a packaged air conditioner or a window air conditioner (mainly used in US market, old generation). If these two components are arranged at two different areas they may be divided into two categories which are wall an air conditioner/ceiling air conditioner, and so called “mother-hold-baby” air conditioner with one condenser unit and plurality of the evaporator units.

In most of the designs the air conditioning apparatus always includes an indoor unit, and may be equipped a control board fixed on the wall, or a handheld remote control (infrared remote control). When using the handheld remote control, the indoor unit of the air conditioning apparatus generally includes a signal receiving face for receiving the air conditioning control signal from the handheld remote control. It is obviously that, the air conditioning apparatus may be controlled by the similar conditioner control means which is operated by users, for example a smartphone device installed a dedicated app, for example.

When the user performs the operation to turn on the air conditioning apparatus, an air conditioning control signal (or a control command) will be transmitted to the air conditioning apparatus to be operated corresponding to setting parameters and/or operating mode according to the control command of the user. Counting from that time, the air conditioning apparatus will generally operate according to the settings of the control command (the initial control command) correctly, until the user proactively changes, for example transmitting a new control command This has been analyzed that it is difficult to achieve the energy-saving purpose if the user does not have a correct habits or consciousness.

In general, conditioning control signals are sent/transmitted to a conditioning apparatus or a group of conditioning apparatus via wired or wireless means according to a typically manner which is sent wirelessly from handhold remote controls, or wiredly from wall-mounted control panels. However, these control signals may be sent via intermedium components or any means which simulates control signals of said wired means or wireless means, for example smartphone, devices that receiving and retransmitting control signals, but not limited thereto. In addition, said devices that receiving and retransmitting control signals may also receive the control signals via many means and in many different manners.

FIG. 1 illustrates a method for energy-saving air conditioning control via QR code according to an embodiment of the present invention.

As shown in FIG. 1, the method for energy-saving air conditioning control via QR code according to the embodiment comprising the steps from S101 to S104 as described in more details hereafter.

The step S101: generating a QR code in the vicinity of a location of an air conditioning apparatus or a group of air conditioning apparatuses corresponding to a predetermined space to be cooled. The QR code may be printed or coated on any material, for example paper, plastic, composite, at a convenient position that facilitates the user to reach and scan the QR code. However, the present invention is not limited thereto, the QR code may be also display in an electronic image form as long as it is of a fixed nature in the vicinity of the location of the corresponding air conditioning apparatus or the corresponding group of the air conditioning apparatuses and convenient for the user to reach and scan the QR code.

The QR code contains an air conditioning apparatus identifier associated with the air conditioning apparatus or the group of air conditioning apparatuses. The air conditioning apparatus identifier may help to define a list including one or more than one air conditioning apparatus corresponding to a predetermined space to be cooled, therefore it is able to precisely control air conditioning apparatus(es) in a space by scanning the QR code which is provided at this space. In addition, it is also favorable for creating preset modes, control modes which are installed according to specific targets (for example, energy-saving), or customized by the owner's needs, ensuring a reasonable use and avoiding arbitrary settings or controls, for example setting the temperature too low, causing waste of electricity.

The present invention may use any system or manner for generating said QR code, and assigning a corresponding air conditioning apparatus or a corresponding group of air conditioning apparatuses associated with the QR code.

Herein, the group of air conditioning apparatuses may be understood in a broad sense, wherein the group of air conditioning apparatuses may include one or more than one air conditioning apparatuses, and other devices as well, such as lighting devices, fans, projectors, multimedia players, electrical equipment or electronic equipment, etc., but not only limited thereto.

The step S102: scanning the QR code by a handheld electronic device. The QR code stands for “Quick Response code”, or also be called “Matrix-barcode” or “two-dimensional (2D) barcode”. In other words, the QR code is a form of information that is encoded for display so that it can be read and decoded, and may contain information such as URL, security code, password, description or an introduction of a certain product, time and location of the event, or any information, for example information which is represented by alphanumeric characters.

One QR code allow relatively large amounts of transmitted information to be contained in the QR code, good support for providing the necessary information thereto.

According to the present invention, the scanning of the QR code having the purpose to retrieve the information contained in the scanned QR code for usage in various embodiments of the present invention.

According to an embodiment, a retrieved information in the QR code may contain at least an URL link, an identifier of the air conditioning apparatus or the group of air conditioning apparatuses corresponding to a space needs to be cooled with QR code scanned. Such that, just by scanning operation on the QR code, the user is able to access an URL link, the URL link may be, such as a web application for example, to access applications which are built on a web platform, for example an air conditioning control interface on the web, but not only limited thereto.

According to another embodiment, the retrieved information in the QR code may contain at least a login password, an identifier of the air conditioning apparatus or the group of air conditioning apparatuses corresponding to a space needs to be cooled with QR code scanned. So that, just by scanning operation on the QR code, the user is able to access applications which are built on a mobile device platform (for example, in apps store Android, iOS, or similar), such as an air conditioning control interface on a smartphone or a handheld electronic device, but not only limited thereto.

The step S103: determining the user identifier.

It is obviously that, to access the air conditioning control interface, or perform control operations therein, the user needs to be determined by the user identifier. If the user identifier is invalid then the user will not be able to access the air conditioning control interface, or not be able to perform control operations therein.

The determination of the user identifier may be performed through various appropriate manners.

For example, the determination of the user identifier may be performed by entering a student code, an employee code, a usage assigned code, or similar codes or characters. These codes may be entered for the first time and will be saved in the electronic device associated with the assigned user, after that when scanning the QR code by the handheld electronic device the determination of the user identifier will be automatically determined using these saved code mentioned above.

According to an example, depending on the choice of the manager or the owner of the conditioning apparatus or the group of conditioning apparatus, the determination of the user identifier may be performed by entering the usage assigned code.

The usage assigned code may be sent to the user from the manager or the owner for a convenience for the management of assigning usage rights to users. The code may be disabled by the manager or the owner after that to prevent the user continue to use the corresponding conditioning apparatus or the corresponding group of conditioning apparatus.

The usage assigned code may be printed, displayed, or expressed in a visible form at a predetermined space to be cooled where there is the corresponding air conditioning apparatus or the corresponding group of air conditioning apparatuses. By this manner, the user only needs to present there for scanning the QR code and entering the usage assigned code to access the air conditioning control interface for controlling the air conditioning apparatus or the group of air conditioning apparatuses there.

It should be understood that the present invention is not limited to any manners used for scanning the QR code and determining the user identifier. Appropriate manners are provided according to different purposes of the manager or the owner when designing the system, and therefore, they are within the scope of the present invention.

The step S104: accessing the air conditioning control interface for controlling the air conditioning apparatus or the group of air conditioning apparatuses, if the user identifier is valid. Preferably, the air conditioning control interface including one or more than one predetermined air conditioning control mode corresponding to the air conditioning apparatus or the group of air conditioning apparatuses associated with said scanned QR code.

In general, the present invention is not just intended to a convenient and effective usage for starting and running the air conditioning apparatus(es) by scanning the QR code and determining the validation off the user identifier, but also intended to other purposes as well, for example energy-saving, by associating the air conditioning apparatus or the group of air conditioning apparatuses with the scanned QR code, it is therefore able to define or preset air specific conditioning control modes for the air conditioning apparatus or the group of air conditioning apparatuses to achieve the expected targets, for example energy-saving.

It is obviously that, the present invention may provide many various different air conditioning control modes, and may select a part of those to provide groups of control modes including one or more than one air conditioning control mode suitable for each practical application. When the air conditioning apparatus or the group of air conditioning apparatuses are associated with a QR code, it may be installed according to a group of control modes as well, thus when the user accesses the air conditioning control interface by scanning the QR code and the user identifier is valid, the air conditioning control interface only displays expected air conditioning control modes in the group of the control modes which are preset for the corresponding air conditioning apparatus or the corresponding group of air conditioning apparatuses. By this manner, the usage of the air conditioning apparatuses is substantially controlled according to expected targets/purposes, for example responding exactly to the actual needs of users, and optimizing subsequent operations, for example soft adjustments within the appropriate temperature range, adjustments following to changes of the surrounding environment, etc., to achieve expected targets, for example energy-saving.

In addition, in several specific applications, the present invention may allow the user to optionally adjust according to user settings at the starting time and running the air conditioning apparatus, this may be performed by setting up an optional air conditioning control mode to facilitate the users who expect to control according to their personal preferences. When the users adjust themselves according to their personal preferences, warnings (for example increasing in the electricity consumption or wasting in the electric energy) may be analyzed and sent to the users.

In the actual usage of an air conditioning apparatus, there may be many different manners provided or designed to satisfy needs of the users well. For example, when using air conditioning apparatus(es) in meeting room, classroom, or similar places, usually of a pre-planned nature, for example the meeting start time, the class start time, or similar start events times, then the turn on plan of the air conditioning apparatus or the group of air conditioning apparatuses before the start time of these events, for example before that time from 5 to 10 minutes or 10 to 20 minutes or a certain predetermined time duration, may provide a significant comfort for users and participants joined said events.

According to above mentioned embodiments, the turning on of the air conditioning apparatus or the group of air conditioning apparatuses only performed by scanning the QR code and validating the user identifier, that means there are only few certain users be able to turn on. To turn on before the start time of said events, those users must be present at the appropriate time, may cause some inconveniences. Therefore, the present invention provides the approach that automatically turns on the air conditioning apparatus or the group of air conditioning apparatuses before the start time of the event in a predetermined time duration (for example, from 5 to 20 minutes). and to ensure that the subsequent use is valid, then it is necessary to have a valid user, who is a user among the certain users be able to turn on mentioned above, to be present there and perform scanning the QR code and to ensure that the determination of the user identifier is valid. If there is not any valid user be present there then the air conditioning apparatus or the group of air conditioning apparatuses will automatically turn off after a predetermined period of time. This not only ensures the usage of the air conditioning apparatus or the group of air conditioning apparatuses is then controlled and responsible by a valid user, but also avoiding an invalid usage, or for some reasons, the event does not take place according to the schedule/plan, the air conditioning apparatus or the group of air conditioning apparatuses after turning on automatically, will turning off automatically after a predetermined period of time, not be forgotten and running in a long period of time while there is no event takes place or there is no one be present there, for example.

Thus, the control of the air conditioning apparatus or the group of air conditioning apparatuses via the air conditioning control interface further comprising a control for maintaining a previously installed operation of the air conditioning apparatus or the group of air conditioning apparatuses, wherein the previously installed operation of the air conditioning apparatus or the group of air conditioning apparatuses is to start and run according to a predetermined schedule during a predetermined time duration. If after this predetermined period of time, a controlling operation for maintaining a previously installed operation is not carried out, then the air conditioning apparatus or the group of air conditioning apparatuses will turn off automatically.

Herein, controlling for maintaining the operation may be understood that keep maintaining the air conditioning apparatus or the group of air conditioning apparatuses in running operation, or it may be understood in another way as not being turned off. It is obviously that, the valid users may change control modes according to their expectations after scanning the QR code and determining the valid user identifier.

According to an embodiment, the air conditioning control interface may be displayed on an application installed in a handheld electronic device which the user uses for scanning the QR code, for example a smartphone. The handheld electronic device may be configured to simulate air conditioning control signals and directly send control commands to the air conditioning apparatus and the group of air conditioning apparatuses to start and run the air conditioning apparatus. Appropriate control modes may be downloaded to the handheld electronic device based on the user identifier assigned corresponding to the specific air conditioning apparatus(es) or the group(s) of the specific air conditioning apparatuses.

According to various embodiments of the present invention, the air conditioning control interface may be connected to the air conditioning apparatus or the group of air conditioning apparatuses by at least one of options including: (i) an intermedium air conditioning control device, (ii) a server, and an intermedium air conditioning control device, and (iii) a server, a gateway, and an intermedium air conditioning control device.

According to an embodiment, the intermedium air conditioning control device is a device with control signal receiving and retransmitting functions. The device with the control signal receiving and retransmitting functions may be provided with any configuration as long as it is capable to carried out the control signal receiving and retransmitting functions.

Receiving control signals may be by any appropriate means, such as by wireless signal, wired signal, combination of wireless and wired manner, directly from control signal sources (for example a user smartphone), or through intermedium devices/systems (for example, through a gateway, or a server and a gateway), for example.

According to an embodiment, the air conditioning control interface is connected to the air conditioning apparatus or the group of air conditioning apparatuses via an intermedium air conditioning control device.

Preferably, the air conditioning control interface is displayed based on an application in the handheld electronic device (for example, a smartphone) which the user uses for scanning the QR code. The intermedium air conditioning control device, may be placed in the vicinity of the air conditioning apparatus or the group of air conditioning apparatuses, which is a device with the control signal receiving and retransmitting functions. The intermedium air conditioning control device may communicate with the handheld electronic device (for example, a direct communication via a near distance wireless communication selected among types of wireless communications which is supportive/available in the handheld electronic device, or communicating via the internet) for receiving the air conditioning control signal or the information of an air conditioning control mode which the user operates on the air conditioning control interface, after that the intermedium air conditioning control device simulates an air conditioning control signal according to the air conditioning control signal or the information of the air conditioning control mode which it received to directly send to the air conditioning apparatus or the group of air conditioning apparatuses. Thus, controlling the air conditioning apparatus or the group of air conditioning apparatuses via the air conditioning control interface operated by the user.

In the other way, the air conditioning control interface may be displayed based on a web application, then the transmission of the handheld electronic device (for example, a smartphone) that the user uses for scanning the QR code needed to be connected to the web server (for example, via the internet), and the intermedium air conditioning control device also needed to be connected to the web server (for example, via the internet). The intermedium air conditioning control device, in a similar way as described above, may be placed at the vicinity of the air conditioning apparatus or the group of air conditioning apparatuses, receiving and retransmitting the air conditioning control signal or the information of the air conditioning control mode from the air conditioning control interface to the air conditioning apparatus or the group of air conditioning apparatuses for controlling the air conditioning apparatus or the group of air conditioning apparatuses via the air conditioning control interface operated by the user.

According to another embodiment, the air conditioning control interface is connected to the air conditioning apparatus or the group of air conditioning apparatuses through a server, and the intermedium air conditioning control device.

Preferably, the air conditioning control interface may be displayed based on an application at the server, then the transmission of the handheld electronic device (for example, a smartphone) that the user uses for scanning the QR code needed to be connected to the server (for example, via the internet), and the intermedium air conditioning control device is also needed to be connected to the server (for example, via the internet).
