< air-conditioning System >
Fig. 1 is a schematic diagram of an air conditioning system according to an embodiment of the present invention. Referring to fig. 1, the air conditioning system 100 of the present embodiment may include an outdoor unit 110, a plurality of indoor units 120, a plurality of controllers 130, and a remote controller 140. The indoor units 120 are further labeled 120_1, 120_2, and 120_ 3. The controller 130 is further labeled 130_1, 130_2, and 130_ 3. A transmitter 145 is provided on the remote controller 140 to transmit the remote control signal, and a receiver is provided on the controller 130 to receive the remote control signal. The controllers 130 are electrically connected to the indoor units 120 in a one-to-one correspondence, and the indoor units 120 are electrically connected to the outdoor unit 110 so as to communicate with the outdoor unit 110. The remote control signal received by each controller 130 may be transmitted to the outdoor unit 110 through a connection path between the corresponding indoor unit 120 and the outdoor unit 110.
In the embodiments of the present invention, such an air conditioning system may be a central air conditioning system or a Variable Refrigerant flow multiple (VRV) air conditioning system. The air conditioning system 100 may be used in business and office applications, as well as in home applications. In commercial and office applications, the indoor units 120 may be distributed in different spaces isolated from each other or in an open space. In a home situation, the indoor units 120 are typically distributed in different spaces isolated from each other, although it is also possible to distribute them in an open space.
In the embodiment of the present invention, the number of the indoor units 120 and the controller 130 is only an example, and may be 2 or more.
In some embodiments of the present invention, the controller 130 may be a built-in controller of the indoor unit 120. In other embodiments of the present invention, the controller 130 may be a control panel of the indoor unit 120. These control panels are typically mounted on a wall and electrically connected to controls inside the indoor unit 120. It is understood that each controller 130 can have different configurations, for example, one portion of the controllers, such as the controller 130_1, is a built-in controller, and the other portion of the controllers, such as the controllers 130_2 and 130_2, is a control panel. Regardless of the configuration, the receiver of the controller 130 needs to have an exposed receiving port in order to receive the remote control signal.
Although fig. 1 shows only one remote controller 140, it is understood that the air conditioning system 100 may include more remote controllers 140. For example, as with the conventional air conditioning system 100, each indoor unit is individually equipped with a remote controller. In these cases, it is desirable that a single remote controller, or at least some of the remote controllers, be able to control at least some of the indoor units 120 in the air conditioning system 100.

Referring to fig. 2 to 3, the remote controller 140 of the present embodiment may include an input unit 143, a master controller 144, a transmitter 145, and a display driving unit 146. The input unit 143, the transmitter 145 and the display driving unit 146 are all connected to the main controller 144. The input unit 143 is, for example, a keyboard scanning circuit, and may be connected to an input section such as the keyboard 141. In an alternative embodiment, the input unit 143 may also be a touch sensing unit, and may be connected to a touch screen. In other embodiments, the input unit 143 may also be a voice input unit or the like. The master controller 144, which is the core of the remote controller, is responsible for transmitting a remote control signal through the transmitter 145 according to the input signal collected by the input unit 143. The transmitter 145 is, for example, an infrared transmitter, a bluetooth transmitter, etc., and is not limited thereto. The display driving unit 146 is connected to the display screen 142. The master controller 144 may transmit necessary information to the display driving unit 146 to be displayed on the display screen.
< pairing method >
The remote controller pairing method is suitable for an air conditioning system with a plurality of indoor units and at least one controller, and the plurality of controllers are associated with the plurality of indoor units. This remote controller pairing method may be applied to the air conditioning system shown in fig. 1, for example. Details of various embodiments of the pairing method are described below.
Fig. 4 is a flowchart of a remote controller pairing method according to an embodiment of the present invention. Referring to fig. 4, the method of the present embodiment includes the following steps:
in step 401, a control signal is sent from a remote controller to a plurality of controllers, wherein the plurality of controllers receiving the control signal is a first set of controllers.
Here, the first set of controllers is part or all of the controllers of the air conditioning system. For example, when the number of controllers is 3, the first set of controllers may be 1-3. The reason why the control signal from the remote controller is transmitted to only a part of the controllers may be that the remote control distance is too far or the signal is blocked. For example, when some controllers are too far apart, they cannot receive control signals from the remote controller. Also, for example, when some controllers are located in a separate isolated space from the user operating the remote controller, they cannot receive control signals from the remote controller. The controllers in the first set of controllers may or may not be in the line of sight of the user.
Here, the control signal may be a normal function signal of the remote controller, such as a power-on signal, or may be a specific signal, such as a pairing signal.
In step 402, the first controller sets respectively receive control signals and report the control signals to the outdoor units.
Here, the first controller set receiving the control signal is responsible for transmitting the control signal to the outdoor unit. When the controller is a built-in controller of the indoor unit, it may directly transmit a control signal to the outdoor unit. When the controller is the control panel of the indoor unit, the controller further transmits a control signal to the outdoor unit through the indoor unit.
In step 403, a control signal is received at the outdoor unit, and a polling signal is sent to the plurality of controllers in response to the control signal, wherein the plurality of controllers receiving the polling signal are the second set of controllers.
Here, the second set of controllers includes the first set of controllers. The second set of controllers may include not only the controllers in the first set of controllers, but may also include additional controllers. That is, the outdoor unit may transmit the polling signal only to those controllers to which the control signal is transmitted, or may transmit the polling signal to more controllers, such as other controllers adjacent to the area where the first controller set is located.
Here, when the controller is a built-in controller of the indoor unit, the outdoor unit may directly transmit the polling signal to the controller. When the controller is the control panel of the indoor unit, the outdoor unit transmits a polling signal to the controller through the indoor unit. The outdoor unit transmits the polling signals twice at a certain interval, so that the controllers receive the polling signals at certain intervals. The order in which the outdoor unit transmits the polling signal to the second controller set may be random or may be instructed in a predetermined order.
At step 404, a polling signal is received at the second set of controllers, and a pairing prompt is presented in accordance with the polling signal.
In this step, the second set of controllers is in a to-be-paired state. As mentioned above, each controller receives the polling signal at regular intervals. And after receiving the polling signal, each controller presents a pairing prompt to the user according to the polling signal. The pairing prompt may let the user know which controller can currently be paired with the remote control. The manner in which the pairing hint is presented may be visual, such as by way of a signal light or blinking. When the controller is a built-in controller of the indoor unit, the controller can control a specific display lamp of the indoor unit to light or flash to present a pairing prompt. When the controller is a control panel of the indoor unit, the controller can control a specific display lamp of the control panel to light or flash to present a pairing prompt. The manner in which the pairing hint is presented may also be auditory or other known manners. In an optimized example, the controller may send a feedback signal to the remote control, and the pairing hint is presented on the remote control according to the feedback signal. Presenting the pairing prompt on the remote control may be visual, audible, or other known means. During presentation of the pairing prompt by a certain controller, if the user wishes to pair with this controller, the remote control may be operated at this point. The time for the controller to present the pairing prompt should last long enough for the user to perceive and complete operation of the remote control, which is, for example, a few seconds.
In step 405, a pairing confirm signal is transmitted from the remote controller.
Here, when the user knows which controller can be paired with the remote controller currently through the pairing prompt, the controller corresponds to the indoor unit that the user wishes to remotely control, and then pairing operation can be performed; otherwise, the user does not operate, waits for the next polled controller to present the pairing prompt, and does not perform the pairing operation until the controller corresponding to the indoor unit which the user wants to remotely control presents the pairing prompt. The pairing operation of the user can be performed by pressing an entity key or a virtual key, or can be performed by voice or the like. When the user performs the pairing operation, the remote controller sends a pairing confirmation signal according to the pairing operation. This pairing confirmation signal is sent to a set of controllers within remote control range of the remote control, e.g. the first set of controllers, if the user has not moved during steps 401 to 405.
At step 406, the controller presenting the pairing prompt is paired with the remote control.
In particular, the pairing confirmation signal typically does not contain the identification number of any device, and the controller will determine whether it is the target controller that the user wishes to pair based on whether it is currently presenting a pairing prompt. If the controller presenting the pairing hint receives the pairing confirm signal, it will consider itself to be the target controller of the user, and therefore proceeds to step 406. On the contrary, if the controller which is not presenting the pairing prompt receives the pairing confirmation signal, the controller considers that the controller is not the target controller of the user, and therefore, no operation can be performed. The controller which is not paired with the remote controller exits the state to be paired after a preset time.
Fig. 5 is a first example of a remote controller pairing method shown in fig. 4. Referring to fig. 1 and 5, the control signal sent from the remote controller 140 according to the user operation may reach all 3 controllers 130_1, 130_2, and 130_3 (step 501), and the controllers 130_1, 130_2, and 130_3 report the control signal to the outdoor unit 110 respectively (step 502). The outdoor unit 110 transmits a polling signal to all the controllers 130_1, 130_2, and 130_3 (step 503). The controllers 130_1, 130_2, and 130_3 present pairing prompts according to the polling signal (step 504). When the controller 130_3 is presenting the pairing prompt, the user operates the remote controller. The remote controller 140 transmits a pairing confirm signal in response to a user operation (step 505). The controller 130_3 presenting the pairing prompt is paired with the remote control 140 (step 506).
After the pairing is completed, if the control signal of step 501 is a functional signal, such as a power-on signal, the controller 130_3 may respond to the control signal. If the control signal of step 501 is itself a pairing signal, no processing is required. In addition, another control signal may be sent from the remote controller 140 (step 507), and the paired controller 130_3 responds to the another control signal to command the corresponding indoor unit 120_3 to execute the another control signal (step 508). The controllers 130_1, 130_2 outside the paired controller stop responding to the other control signal. That is, only the pairing controller 130_3 responds to the control signal of the remote controller 140 at a time after the pairing is completed.
The more complete flow of fig. 5 may complete the description of the above embodiments and will not be further expanded herein.
There is a case where a target controller that a user wishes to pair is not within a remote control range of a remote controller, and fig. 6 is a second example of a remote controller pairing method of the present invention. Referring to fig. 6, a control signal transmitted from the remote controller 140 may reach 2 controllers 130_1 and 130_2 (step 601). However, the user's target controller is 130_3, which is not within the remote control range of the remote control. At this time, the controllers 130_1 and 130_2 report control signals to the outdoor unit 110, respectively (step 602). The outdoor unit 110 sends a polling signal to the controllers 130_ and 130_2 that have previously received and reported the control signal (step 603). The controllers 130_1 and 130_2 present a pairing hint according to the polling signal (step 604). Since the target controller 130_3 does not present the pairing prompt, the user may recognize that the controller is not in the remote control range of the remote controller after finding, and move to the target controller to perform pairing again. The process of pairing again will be as shown in figure 5.
Preferably, it is desirable to complete pairing immediately when the target controller that the user wishes to pair is not within the remote control range of the remote controller. Fig. 7 is a third example of a remote controller pairing method of the present invention. As shown in fig. 7, a control signal transmitted from the remote controller 140 may reach a first controller set consisting of 2 controllers 130_1 and 130_2 (step 701). However, the user's target controller is 130_3, which is not within the remote control range of the remote control. The controllers 130_1 and 130_2 report control signals to the outdoor unit 110, respectively (step 702). The outdoor unit 110 sends a polling signal to the second controller set formed by all the controllers 130_1, 130_2, and 130_3 (step 703), which is more than the controller sets 130_1 and 130_2 that have received and reported the control signal, and at this time, the target controller 130_3 also receives the polling signal. The controllers 130_1, 130_2, and 130_3 present the pairing hint according to the polling signal (step 704), and the target controller 130_3 also has an opportunity to present the pairing hint. When the controller 130_3 presents the pairing prompt, the user operates the remote controller. The remote controller 140 transmits a pairing confirm signal in response to a user operation (step 705). Likewise, the pairing confirmation signal can only reach the first set of controllers 130_1, 130_ 2. Therefore, in step 706, the controller of the first controller set consisting of the controllers 130_1 and 130_2 that received the pairing check signal reports the pairing check signal to the outdoor unit 110, and in step 707, the outdoor unit 110 forwards the pairing check signal to the controller 130_3 that did not report the pairing check signal (this indicates that the controller did not receive the pairing check signal). When the controller 130_3 presenting the pairing hint receives the pairing confirm signal through the outdoor unit 110, not wirelessly, it determines that it is not within the remote control range of the remote controller 140. At this time, the controller 130_3 may perform pairing (step 708) and simultaneously present a distance warning (step 709), so that the user knows that the indoor unit that he desires to remotely control is not within the remote control range, thereby moving the user to the target indoor unit. Thus, after the pairing is completed, the paired controller 130_3 is already within the remote control range of the remote controller 140.
Similarly, after the pairing is completed, if the control signal of step 701 is a functional signal, such as a power-on signal, the controller 130_3 may respond to the control signal. If the control signal of step 701 is itself a pairing signal, no processing is required. In addition, another control signal may be transmitted from the remote controller 140 (step 710), and the paired controller 130_3 may command the corresponding indoor unit 120_3 to execute another control signal in response to the another control signal (step 711). The controllers 130_1, 130_2 outside the paired controller stop responding to the other control signal. That is, only the pairing controller 1303 responds to the control signal of the remote controller 140 at a time after the pairing is completed.
Fig. 8 is a fourth example of a remote controller pairing method of the present invention. As an alternative to the third example, the steps 801 and 807 of the present example are similar to the steps 701 and 707 of FIG. 7, but there is no distance warning step in the step 709, and the other controllers 130_1 and 130_2 of the air conditioning system relay the subsequent control signals. Specifically, after the controller 130_3 presenting the pairing prompt is paired with the remote controller 140 in step 808, if the controller 130_1 or 130_2 other than the paired controller 130_3 receives another control signal (step 809), the outdoor unit 110 reports the another control signal to the outdoor unit 110 (step 810), and the outdoor unit 110 sends the another control signal to the paired controller 130_3 (step 811), and the paired controller 130_3 instructs the corresponding indoor unit 120_3 to execute the another control signal in response to the another control signal (step 812).
Embodiments of the present invention also allow the remote to initiate pairing with other controllers. Fig. 9 is a flowchart of a remote controller re-pairing method according to an embodiment of the invention. Referring to fig. 9, the method includes the steps of:
in step 901, a re-pairing signal is sent from the remote controller to a plurality of controllers, wherein the plurality of controllers receiving the re-pairing signal is a third set of controllers.
Here, the third set of controllers is part or all of the controllers of the air conditioning system. For example, when the number of controllers is 3, the third set of controllers may be 1-3. Here, the third set of controllers may be the same as the first set of controllers or may be different from the first set of controllers, taking into account that possible movements of the user and his handheld remote control result in a change in the remote control range.
The generation of the re-pairing signal may be such that the remote controller generates the re-pairing signal in response to the pairing key being pressed by the user. I.e. the triggering condition for the remote control to generate the re-pairing signal may be that the pairing key is pressed. The triggering condition for the remote controller to generate the re-pairing signal may further include one or more of operation duration and operation interval.
In step 902, the third controller sets respectively receive the re-pairing signals and report the re-pairing signals to the outdoor units.
Here, the third controller set receiving the re-pairing signal is responsible for transmitting the signal to the outdoor unit.
In step 903, a re-pairing signal is received at the outdoor unit, and a polling signal is sent to the plurality of controllers in response to the re-pairing signal, wherein the plurality of controllers receiving the polling signal are not the fourth controller set.
Here, the fourth set of controllers includes the third set of controllers. The fourth set of controllers may include not only the controllers in the third set of controllers, but may also include additional controllers. That is, the outdoor unit may transmit the polling signal only to those controllers to which the control signal is transmitted, or may transmit the polling signal to more controllers, such as other controllers adjacent to the area where the third controller set is located. After that, the fourth set of controllers may no longer respond to the general control signals of the remote controller until the re-pairing is completed. The fourth set of controllers may include previously paired controllers that cease to respond to the general control signals of the remote control. The fourth controller set may not include the previously paired controller, and the outdoor unit may additionally send a pairing stop signal to the previously paired controller to stop responding to the general control signal of the remote controller.
In step 904, a polling signal is received at the fourth set of controllers, and a pairing prompt is presented to the user according to the polling signal, where the fourth set of controllers is in a state to be paired.
In step 905, a pairing confirm signal is transmitted from the remote controller.
At step 906, the controller presenting the pairing prompt is paired with the remote control.
The flow shown in fig. 9 is similar in principle to the flow shown in fig. 4, and thus reference may be made to fig. 4 and its examples shown in fig. 5-8 for further details of fig. 9.
Although the present invention has been described with reference to the present specific embodiments, it will be appreciated by those skilled in the art that the above embodiments are merely illustrative of the present invention, and various equivalent changes and substitutions may be made without departing from the spirit of the invention, and therefore, it is intended that all changes and modifications to the above embodiments within the spirit and scope of the present invention be covered by the appended claims.
