Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The inventor researches and discovers that when the dual-system air conditioner operates in the dual-system mode, the traditional method for controlling the display panel adopts the operation of the single-system air conditioner. That is, there is no parameter synchronization and cooperative control between the two display panels, and the user's operation is performed completely independently. Because there is not communication between two display panels, if the air conditioner control parameter that the user set for two display panels is different, for example, parameters such as running mode, fan gear, target temperature are different, cause load damage such as compressor, electric heater, fan among the air conditioning unit easily for the security of dual system air conditioner is relatively poor.
In view of the above, the inventor proposes a method for controlling a display panel to implement display panel cooperative control of a dual-system air conditioner. The following is a detailed description.
Some embodiments of the method of controlling a display panel of the present disclosure are first described in conjunction with fig. 1.
Fig. 1 illustrates a flow diagram of a method of controlling a display panel according to some embodiments of the present disclosure. As shown in fig. 1, the present embodiment includes steps S101 to S103.
In step S101, the on/off states of two display panels of the dual system air conditioner are acquired.
It should be understood by those skilled in the art that the on/off states of the two display panels are independent of each other, and can be in the on state and the off state, respectively.
In step S102, priorities of two display panels of the dual system air conditioner are determined according to on and off states of the two display panels, respectively.
The on/off states of the two display panels can be divided into three cases. The first case is where both display panels are in the on state; the second situation is that one display panel is in a power-on state and the other display panel is in a power-off state; the third situation is that both display panels are in a power-off state. For these three cases, the priority of the two display panels may be determined with different strategies, which will be described in detail later.
In step S103, the air conditioner control parameter on the display panel having the high priority is synchronized to the display panel having the low priority.
The air conditioner control parameter may specifically be a set temperature, an operation mode, a fan gear, and the like. When the parameter synchronization operation is executed, the display panel with high priority CAN be controlled to send the air conditioner control parameters on the display panel to the CAN bus in the form of a synchronous data frame, and the synchronous data frame contains the air conditioner control parameters and the address of the display panel with high priority. When the display panel with low priority detects the synchronous data frame containing the address of the display panel with high priority in the CAN bus, the air-conditioning control parameter on the display panel with high priority in the synchronous data frame CAN be used as the air-conditioning control parameter of the display panel.
After the synchronous execution of the parameters is completed, the air conditioner control parameters on the display panel with the high priority CAN be sent to the first main board through the CAN bus in the form of a first control data frame, and the first control data frame comprises the air conditioner control parameters and the address of the first main board, so that the first main board CAN control the first air conditioning system in the dual-system air conditioner by using the air conditioner control parameters on the display panel with the high priority. And meanwhile, the air-conditioning control parameters on the display panel with the low priority are sent to the second main board through the CAN bus in the form of a second control data frame, and the second control data frame comprises the air-conditioning control parameters and the address of the second main board, so that the second main board controls a second air-conditioning system in the dual-system air conditioner by using the air-conditioning control parameters on the display panel with the low priority.
The embodiment realizes cooperative control of the two display panels in the dual-system air conditioner, can automatically synchronize air conditioner control parameters on the two display panels in the dual-system air conditioner, does not need to be manually set by a user respectively, and avoids the condition that the air conditioner control parameters on the two display panels in the dual-system air conditioner are possibly different, thereby improving the safety, stability and reliability of the dual-system air conditioner.
How to determine the priority of two display panels is described below in conjunction with fig. 2.
Figure 2 illustrates a flow diagram of some embodiments for determining priority of two display panels. As shown in fig. 2, step S202 in fig. 1 specifically includes steps S2020 to S2023.
In step S2020, the on/off state of the two display panels is determined.
In the case where both display panels are in the power-off state, step S2021 is performed. In step S2021, the priority of one of the display panels is determined to be high priority, and the priority of the other display panel is determined to be low priority.
In the case where one of the display panels is in the on state and the other display panel is in the off state, step S2022 is performed. In step S2022, the priority of the display panel in the power-on state is determined to be high, and the priority of the display panel in the power-off state is determined to be low.
In the case where both display panels are in the on state, step S2023 is performed. In step S2023, the display panel with the air-conditioning control parameter changed is determined to have a high priority, and the display panel without the air-conditioning control parameter changed is determined to have a low priority.
This embodiment has realized carrying out cooperative control's control logic to two display panels in the dual system air conditioner for two display panels all can realize the automatic synchronization of air conditioner control parameter under various on-off state, thereby avoided the probably different condition of air conditioner control parameter on two display panels in the dual system air conditioner, thereby promote security, stability and the reliability of dual system air conditioner.
In some embodiments, step S2024 to step S2025 are further included.
In step S2024, a duration in which the air-conditioning control parameter on the display panel having the high priority is different from the air-conditioning control parameter on the display panel having the low priority is detected.
In the case where the duration is greater than the preset time, step S2025 is performed. In step S2025, the foregoing synchronization operation is repeatedly performed a plurality of times in succession. For example, it is possible to control the display panel having a high priority to repeatedly transmit the synchronization data frame to the CAN bus a plurality of times in succession so that the display panel having a low priority repeatedly detects the synchronization data frame containing the address of the display panel having a high priority in the CAN bus a plurality of times in succession, and to use the air-conditioning control parameter on the display panel having a high priority in the synchronization data frame as the air-conditioning control parameter of itself.
In the case where the duration is not greater than the preset time, execution returns to step S2024. Meanwhile, the two display panels respectively send air conditioner control parameters to the corresponding main boards.
The preset time may be, for example, 10 seconds. Those skilled in the art will appreciate that the preset time can be adjusted according to actual conditions. The forced synchronization of the air conditioner control parameters is carried out when the different durations of the air conditioner control parameters on the two display panels are longer, so that the negative effects caused by the synchronization failure of the air conditioner control parameters due to the failure of a communication link and the like can be compensated in time, the condition that the air conditioner control parameters on the two display panels in the dual-system air conditioner are different is avoided in real time, and the safety, the stability and the reliability of the dual-system air conditioner are improved.
Further embodiments of the method of controlling a display panel of the present disclosure are described below in conjunction with fig. 3.
Fig. 3 illustrates a flow diagram of a method of controlling a display panel according to some embodiments of the present disclosure. As shown in fig. 3, the present embodiment includes steps S3001 to S3003.
In step S3001, it is detected whether the device addresses of the two display panels are the same, and whether the device addresses of the two main boards controlled by the two display panels, respectively, are the same.
After the two display panels are electrified, various data frames CAN be respectively sent to the CAN bus. These data frames include in particular the aforementioned synchronization data frames, control data frames, and also status data frames. The status data frame includes status parameters of the display panel (such as on/off status, operation mode, fan gear voltage, set temperature, temperature set value, etc.) and also includes device address of the display panel.
When detecting whether the device addresses of two display panels (respectively called as a first display panel and a second display panel) are the same, the first display panel CAN be controlled to detect the device address in a state data frame and a synchronous data frame sent by the second display panel on the CAN bus and judge whether the device address is the same as the self device address. When detecting whether the device addresses of the two mainboards controlled by the two display boards are the same or not, the first display board CAN be controlled to detect the device address in the control data frame sent by the second display board on the CAN bus, and whether the device address is the same as the device address in the self-sent control data frame or not is judged. It will be understood by those skilled in the art that the order between detecting whether the device addresses of the two display panels are the same and detecting whether the device addresses of the two motherboards controlled by the two display panels respectively are the same can be adjusted.
In the case where the device addresses of the two display panels are the same or the device addresses of the two main boards are the same, step S3002 is performed. In step S3002, the two display panels are controlled to display the failure codes of the device address conflicts, respectively, to indicate that the device address conflict failure occurs.
If the device address conflict fault has occurred and the display panel displays the fault code, it returns to step S3001 for further determination.
In the case where the device addresses of the two display panels are different and the device addresses of the two main boards are different, indicating that the device address conflict fault has been resolved, step S3003 is performed. In step S3003, the two display panels are controlled to display the air conditioning control parameters, respectively, and the two display panels operate normally.
It should be understood by those skilled in the art that, in the embodiment corresponding to fig. 1, after the display panel sends the air conditioner control parameter to the motherboard, step S3001 in this embodiment may be returned to circularly detect whether there is an address conflict fault of the device.
The embodiment realizes the detection of the equipment address conflict fault in the dual-system air conditioner, and can ensure that the equipment addresses in the dual-system air conditioner do not conflict before the air conditioner control parameters of the synchronous display panel, thereby further improving the safety, stability and reliability of the dual-system air conditioner.
