As shown in fig. 1, the multiple systems may include a first air conditioning system and a second air conditioning system.

Fig. 2 is a flow diagram of a method of synchronization for multiple systems, according to some embodiments of the present disclosure.
The synchronization method for multiple systems is described below with reference to fig. 1 and 2.
In step 202, the first display panel monitors a second control frame sent by the second display panel to the second motherboard at a preset time interval. Here, the second control frame carries a second parameter for controlling the second air conditioning system.
For example, the second display panel may send the second control frame to the second main board every 5 seconds, where the second control frame sent each time carries the current second parameter. As an example, the second parameter may include, but is not limited to, information of an operation mode, a wind speed, a set temperature, and the like. The second main board can control the second air conditioning system to operate according to the second parameter in the second control frame.
In step 204, the first display panel synchronizes a first parameter currently controlling the first air conditioning system to a second parameter in the second control frame or the second synchronization frame.
Here, the second sync frame is transmitted to the first display panel by the second display panel in response to a change of the second parameter, and the second sync frame carries the changed second parameter. In some embodiments, the second display panel may transmit the second sync frame to the first display panel a plurality of times, for example, 3 times consecutively, in response to the change of the second parameter.
Since the second control frame is sent by the second display panel at the preset time interval, after the second parameter is changed, the second parameter carried in the second control frame sent by the second display panel is also changed, that is, the second parameter is also changed.
For example, in case that the user changes the second parameter through the second display panel, the user may control the second display panel to transmit the second sync frame to the first display panel. For example, the user may control the second display panel to transmit the second sync frame to the first display panel by touching a specific key, a specific icon, or the like on the second display panel, so that the first display panel synchronizes the current first parameter to the modified second parameter.
It should be understood that after synchronization, the first control frame sent by the first display panel to the first main board carries the synchronized first parameter, i.e. the modified second parameter. Therefore, the first main board can control the first air conditioning system based on the synchronized first parameter, so that the first air conditioning system and the second air conditioning system can synchronously run.
In some embodiments, referring to fig. 1, the second display panel may transmit the second control frame and the second sync frame through a CAN (controller area network) bus. Accordingly, the first display panel may listen for the second control frame and receive the second synchronization frame through the CAN bus.
In the above embodiment, the first display panel may listen to the second control frame transmitted by the second display panel at the preset time interval, or may receive the second synchronization frame transmitted by the second display panel in case of the second parameter being changed. In case that the second parameter is changed, the first display panel may synchronize the current first parameter to the second parameter in the second control frame or the second synchronization frame. In this manner, when the second parameter for controlling the second air conditioning system is changed, the first parameter for controlling the first air conditioning system can be synchronized with the changed second parameter in time.
In some embodiments, the first display panel may synchronize the current first parameter to the second parameter in the second control frame or the second synchronization frame according to the operation states of the first air conditioning system and the second air conditioning system.
The following describes a specific implementation manner of the step 204 in conjunction with the operation states of the first air conditioning system and the second air conditioning system.
In some implementations, in a case where both the first air conditioning system and the second air conditioning system are in an operating state: if the first display panel receives the second sync frame, the first display panel synchronizes the current first parameter to the second parameter in the second sync frame. In this case, the first display panel still hears the second control frame transmitted by the second display panel, but does not perform synchronization according to the second control frame.
In the above implementation, the first display panel may perform synchronization according to the second synchronization frame when the second parameter is changed and the second synchronization frame is received, so as to ensure synchronization between the first parameter and the second parameter. If one air conditioning system fails, the other air conditioning system can continue to operate according to the previous parameters.
It will be appreciated that the first display panel becomes unable to synchronize according to the second sync frame if the second sync frame is not received. Considering that in some scenarios, the second display panel transmits the second synchronization frame, but the first display panel does not receive the second synchronization frame due to a temporary communication failure or power failure, etc., in this case, in order to ensure the synchronization between the first parameter and the second parameter, the following process may be performed.
In some implementations, if the first display panel does not receive the second synchronization frame and the current first parameter has a different duration than the second parameter in the second control frame for more than a preset time, the first display panel synchronizes the current first parameter to the second parameter in the second control frame.
For example, the first display panel monitors that the current first parameter is different from the second parameter in the second control frame for consecutive 10 s. In this case, the first display panel may perform synchronization according to the monitored second control frame to ensure synchronization between the first parameter and the second parameter.
In other implementations, in the case where the first air conditioning system is in an inactive state and the second air conditioning system is in an active state: each time the second control frame is monitored, the first display panel synchronizes the current first parameter to the second parameter in the second control frame; if the second sync frame is received, the first display panel synchronizes the current first parameter to the second parameter in the second sync frame.
In the above implementation manner, no matter the second control frame is monitored or the second synchronization frame is received, the current first parameter is synchronized. This way it is ensured that the first parameter can still be synchronized with the second parameter in case the first air conditioning system is not in operation. If the second air conditioning system fails, the user may turn on the first air conditioning system so that operation may continue according to the previous parameters.
In still other implementations, in the event that both the first air conditioning system and the second air conditioning system are in an inactive state: each time a second control frame is heard, the first display panel synchronizes the current first parameter to the second parameter in the second control frame. In this case, the first display panel may be regarded as a slave display panel, and the second display panel may be regarded as a master display panel.
In the implementation manner, when the first air conditioning system and the second air conditioning system are both in the non-operating state, the first display panel performs synchronization according to the second control frame sent by the second display panel to ensure synchronization between the first parameter and the second parameter, so that the operating states of the first air conditioning system and the second air conditioning system can be automatically kept consistent when the non-operating state is changed into the operating state.
FIG. 3 is a flow diagram of a method for synchronization of multiple systems according to further embodiments of the present disclosure.
Step 302 and step 304 shown in fig. 3 can refer to the above description of step 202 and step 204, and are not described herein again. In addition, the execution order of step 306 and step 308 is not limited, the execution order of step 306 and step 302 and step 304 is also not limited, and the execution order of step 308 and step 302 and step 304 is also not limited.
In step 302, the first display panel monitors a second control frame sent by the second display panel to the second motherboard according to a preset time interval, where the second control frame carries a second parameter for controlling the second air conditioning system.
In step 304, the first display panel synchronizes a first parameter currently controlling the first air conditioning system to a second parameter in the second control frame or the second synchronization frame.
In step 306, the first display panel sends a first control frame to the first motherboard at a preset time interval, where the first control frame carries a first parameter for controlling the first air conditioning system.
Here, the preset time interval for the first display panel to transmit the first control frame and the preset time interval for the second display panel to transmit the second control frame may be the same or different.
The first display panel may determine the address of the second display panel and the address of the first main board based on its own address. Similarly, the second display panel may determine the address of the first display panel and the address of the second main board based on its own address. For example, after the first display panel is started, the address of the second display panel and the address of the first main board can be determined; after the second display panel is started, the address of the first display panel and the address of the second main board can be determined.
As an example, addresses 0X40 and 0X41 of two display panels and addresses 0X01 and 0X02 of respective corresponding main boards may be preset. If the address of the first display panel is 0X40, the address of the second display panel is 0X41, and the address of the corresponding first main board is 0X 01; if the address of the first display panel itself is 0X41, the address of the second display panel is 0X40, and the corresponding address of the first main board is 0X 02.
In response to the change of the first parameter, the first display panel transmits a first synchronization frame to the second display panel, the first synchronization frame carrying the changed first parameter, so that the second display panel synchronizes a second parameter currently controlling the second air conditioning system to the first parameter in the first control frame or the first synchronization frame, in step 308.
For example, the first display panel may transmit the first sync frame and the first control frame through the CAN bus. Accordingly, the second display panel may receive the first sync frame through the CAN bus and listen for the first control frame.
It should be understood that after synchronization, the second control frame sent by the second display panel to the second main board carries the synchronized second parameter, i.e. the modified first parameter. Therefore, the second main board can control the second air conditioning system based on the synchronized second parameter, so that the second air conditioning system and the first air conditioning system keep synchronous operation.
Similarly, the second display panel may synchronize the current second parameter to the second parameter in the first control frame or the first synchronization frame according to the operation states of the first air conditioning system and the second air conditioning system. The specific synchronization method can be referred to the above description related to the synchronization of the first display panel.
In the above-described embodiment, in the case where the second parameter is changed, the first display panel may synchronize the current first parameter to the second parameter in the second control frame or the second synchronization frame; in case that the first parameter is changed, the second display panel may synchronize the current second parameter to the second parameter in the first control frame or the first synchronization frame. In this way, in the case of a change of the second parameter, the first parameter can be synchronized in time with the changed second parameter; in case of a change of the first parameter, the second parameter can be synchronized with the changed first parameter in time, so that the first parameter and the second parameter can be synchronized with each other.
In some embodiments, in the case where both the first air conditioning system and the second air conditioning system are in an operating state: the first display panel may synchronize the first parameter to the modified second parameter according to the second sync frame if the second parameter is changed; and if the first display panel does not receive the second synchronization frame and the current first parameter has a different duration from the second parameter in the second control frame that exceeds a preset time, the first display panel may synchronize the first parameter to the modified second parameter according to the second control frame.
In addition, if the first parameter is changed, the second display panel may synchronize the second parameter to the modified first parameter according to the first synchronization frame; and if the second display panel does not receive the first synchronization frame, the second display panel does not synchronize the second parameter with the modified first parameter even if the duration of the current second parameter different from the first parameter in the first control frame exceeds the preset time.
In this way, only the first display panel performs the synchronization operation, avoiding the interchange of parameters caused by the first display panel and the second display panel performing the synchronization operation, for example, the first parameter is synchronized to the modified second parameter, and the second parameter is synchronized to the modified first parameter, so that the first parameter and the second parameter still cannot be the same.
Fig. 4 is a flow diagram of a method of synchronization for multiple systems in accordance with further embodiments of the present disclosure.
In step 402, the first display panel sends a first control frame to the first motherboard at a preset time interval, where the first control frame carries a first parameter for controlling the first air conditioning system.
In response to the change of the first parameter, the first display panel transmits a first synchronization frame to the second display panel, the first synchronization frame carrying the changed first parameter, so that the second display panel synchronizes a second parameter currently controlling the second air conditioning system to the first parameter in the first control frame or the first synchronization frame, in step 404.
In the above embodiment, the first display panel transmits the second control frame at the preset time interval and transmits the first sync frame in case the first parameter is changed. So that the second display panel can synchronize the current second parameter to the first parameter in the first control frame or the first synchronization frame in case the first parameter is changed. In this manner, when the first parameter for controlling the first air conditioning system is changed, the second parameter for controlling the second air conditioning system can be synchronized with the changed first parameter in time.
In some embodiments, the first synchronization frame may employ a higher priority function code than the first control frame, both of which may use different labels and data formats. Similarly, the second synchronization frame may employ a higher priority functional code than the second control frame, both of which may use different labels and data formats.
In the present specification, the embodiments are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same or similar parts in the embodiments are referred to each other. For the display panel embodiment, since it substantially corresponds to the method embodiment, the description is relatively simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
