Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 exemplarily shows a system architecture to which an embodiment of the present invention is applicable, and the system architecture may include a control terminal 100, a cloud server 200, a gateway 300, a protocol conversion module 400, and a central air conditioner 500.
Wherein, the control terminal 100 may be installed with an intelligent home APP for managing and controlling the corresponding central air conditioner 500. The control terminal 100 may communicate with the cloud server 200 through the internet.
The cloud server 200 may communicate with the gateway 300 through the router/switch to obtain the data reported by the gateway 300.
The gateway 300 is used to establish a ZigBee network so that the central air conditioner 500 is accessed through the protocol conversion module 400.
The protocol conversion module 400 is used for converting the data protocol of the central air conditioner 500 into a protocol recognizable by the gateway 300, so that the central air conditioner 500 can communicate with the gateway 300 conveniently. The protocol conversion module can be a converter for converting ZigBee into 485 protocol.
The central air conditioner 500 may be connected to the gateway 300 through the protocol conversion module 400, or may be directly connected to and communicate with the gateway 300 through an IP method. The central air conditioner 500 is provided with an air conditioner controller for controlling the operation of the central air conditioner, and may be a VRV controller, for example. The central air conditioner 500 is mainly connected to the gateway 300 or the protocol conversion module 400 through an air conditioner controller.
It should be noted that the structure shown in fig. 1 is only an example, and the embodiment of the present invention is not limited thereto.
Based on the above description, fig. 2 shows in detail a flow of a method for synchronizing states of a control terminal and a central air conditioner according to an embodiment of the present invention, where the flow may be performed by a device for synchronizing states of the control terminal and the central air conditioner, and the device may be located in the control terminal 100 shown in fig. 1, or the control terminal 100.
As shown in fig. 2, the process specifically includes:
In the embodiment of the present invention, the first device state of the central air conditioner is a device state that is queried by the control terminal by sending a state query instruction last time, or is fed back to the cloud server by the gateway after periodically querying the device state of the central air conditioner.
When the control terminal enters the page of the control terminal, the control terminal firstly acquires the central air conditioner state stored in the cloud. The central air conditioner state stored in the cloud end can be the equipment state inquired by the control terminal when the control terminal sends a state inquiry command to the central air conditioner at the previous time, or the equipment state of the central air conditioner obtained by the gateway through timing inquiry after the central air conditioner equipment is bound to the wireless gateway, so that the central air conditioner state is fed back to the cloud end server and is pushed to the control terminal by the cloud end server. The action of the gateway for periodically inquiring the equipment state of the central air conditioner is executed periodically all the time, the action is irrelevant to the login state of the smart home APP in the control terminal, whether a user logs in the smart home APP to check the equipment state of the central air conditioner or not, the gateway can perform periodic inquiry, an inquiry result is fed back to the cloud server, and then the inquiry result is pushed to the control terminal by the cloud server.
And step 202, the control terminal updates the state displayed on the control equipment page of the control terminal according to the first equipment state of the central air conditioner.
After the control terminal obtains the first device state, the state displayed on the control device page can be updated according to the first device state.
After the control terminal updates the state displayed on the control equipment page, the control terminal can also continue to send a state query instruction to the central air conditioner so that the central air conditioner can feed back the current equipment state, and then the state displayed on the control equipment page of the control terminal is updated according to the current equipment state, so that the condition that the state of the air conditioner equipment is not changed and the state is not obtained in time can be avoided.
It should be noted that there are two ways for the central air conditioner to access the gateway, where the central air conditioner is connected to the gateway through the ZigBee to 485 protocol converter. A specific system architecture may be as shown in fig. 3. At the moment, the VRV controller is accessed to a control system of the central air conditioner; then, the VRV controller equipment is connected to the gateway through a ZigBee-to-485 protocol converter; the gateway communicates with the cloud server and the APP over a wide area network (internet).
Under the system architecture shown in fig. 3, when the control terminal sends the status query instruction to the central air conditioner, the control terminal mainly sends the status query instruction to the gateway, so that the gateway sends the status query instruction to the central air conditioner through the ZigBee-to-485 protocol converter. The ZigBee-to-485 protocol converter inserts the state query instruction into the current queuing instruction after the instruction in the processing state, so that the equipment state of the central air conditioner can be quickly identified. In this case, when the gateway periodically inquires the central air conditioner about the status of the device, the central air conditioner is periodically inquired a plurality of times in a grouped manner.
In the practical application process, the mode of realizing the state consistency between the control terminal and the central air conditioner can be as follows:
1. and the control terminal adds a query instruction. When the control equipment page enters the equipment detail page, the control terminal firstly acquires the current equipment state stored in the cloud, and then issues a query instruction to acquire the latest equipment state of the central air conditioner. Because zigbee is limited by a 485 protocol, all control instructions or query instructions need to be controlled in a queuing mode, the control terminal should wait in a queuing mode when issuing the query instructions, but the control terminal is expected to feed back the equipment state of the central air conditioner in time, the query instructions issued by the control terminal are processed in an insertion queuing mode at this time, namely the query instructions are inserted into the current queuing instructions and are in the processing state, and other control instructions continue to be processed in the queuing mode.
2. The gateway adds a periodic query instruction. After the Zigbee 485 protocol converter is connected to the network, the gateway analyzes the configuration file of the central air conditioner, and at the moment, a periodic query instruction of the gateway is started. The specific implementation scheme of the periodic query is as follows: because the number of the central air conditioner internal units is large, the periodical query instruction is queried in a grouping mode, and the three air conditioner internal units are used as a group for querying; the query is divided into two times, the online and offline state of the central air conditioner is firstly queried, when the central air conditioner returns to be online, the specific air conditioner parameters are queried, and when the central air conditioner returns to be offline, the command for querying the specific data parameters does not need to be issued again; the air conditioner grouping algorithm adopts three groups of random distribution, and the air conditioner grouping algorithm is automatically grouped into one group when the number of the air conditioner groups is less than three.
Another way of a central air conditioning access gateway is a direct access gateway based on IP protocol. The system architecture can be as shown in fig. 4, the VRV controller is connected to the control system of the central air conditioner; then connecting the VRV controller equipment to the gateway through IP; the gateway communicates with the cloud server and the APP over a wide area network (internet).
In the practical application process, the mode of realizing the state consistency between the control terminal and the central air conditioner can be as follows:
1. and the control terminal adds a query instruction. When the control device page enters the device detail page, the control terminal firstly acquires the current device state stored in the cloud, and then issues a query instruction to acquire the latest state of the device terminal. Because the communication state of the IP protocol is relatively good, all control instructions or query instructions can be fed back in time, and therefore, the conventional processing is adopted.
2. The gateway adds a periodic query instruction. After the IP mode is connected with the central air conditioner, the configuration file of the central air conditioner is analyzed after the gateway is started, and a periodic query instruction of the gateway is started. The specific implementation scheme of the periodic query is as follows: the processing speed of the IP mode can be suitable for inquiring the states of a plurality of central air conditioners at one time, so that a mechanism of inquiring the states of all air conditioners at one time is adopted for a periodic inquiry command, the inquiry mode is still divided into two times, the online and offline states of all the air conditioners are inquired firstly, when the online and offline states are returned, specific air conditioner parameters are inquired, and when the offline state is returned, the command for inquiring the specific data parameters is not required to be issued again.
Through the specific implementation of the two modes, the user experience of timely inquiring the equipment state of the central air conditioner through the control terminal is improved when the central air conditioner is accessed into a wireless system.
The embodiment shows that the control terminal obtains the first device state of the central air conditioner sent by the cloud server, the first device state of the central air conditioner is fed back to the cloud server after the gateway periodically queries the device state of the central air conditioner, and the state displayed on the control device page of the control terminal is updated according to the first device state of the central air conditioner. The gateway can periodically inquire the equipment state of the central air conditioner, and when the control terminal carries out the equipment detail page of the control terminal, the equipment state obtained by the periodic inquiry of the gateway can be automatically acquired from the cloud and is updated according to the equipment state, so that the problem that the central air conditioner does not automatically report the equipment state can be solved, the equipment state of the control terminal is consistent with the central air conditioner, and the user experience is improved.
