With the increasing popularization rate of cloud intelligent gas water heaters with WIFI functions, remote controllers are developed in a wireless WIFI mode, and the remote controllers are feasible to communicate with the gas water heaters, but pairing and control schemes of the remote controllers are different for different manufacturers. Meanwhile, the user has a high requirement on the success rate of control, if control fails, if the water outlet temperature is set to be 50 ℃, the user still considers that the control is successful, and showering is performed, so that the user experience is influenced. Obviously, the communication between the WIFI remote controller and the water heater is affected by the strength and the distance of the router signal in the LAN, so that control failure and packet loss may occur, compensation cannot be performed, and user experience is affected.
Meanwhile, according to the size of the area of a household, one household gas water heater may be provided with more than one WIFI remote controller, and how to pair and control the plurality of remote controllers also becomes a problem to be solved urgently.
The remote control method for the water heater can be applied to the application environment shown in fig. 1. The remote controller 102 may communicate with the water heater 104 through a local area network, and the number of the remote controllers 102 may be multiple; further, in the application of the internet of things of the water heater, the water heater 104 may be controlled (for example, remotely controlled) by the intelligent terminal 106 based on the cloud server, and the intelligent terminal 106 may run a corresponding APP, that is, the APP remotely controls the water heater 104; the remote controller 102 may be a WIFI remote controller, the water heater 104 may be a gas water heater, the intelligent terminal 106 may be but is not limited to various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the cloud server may be implemented by an independent server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a remote control method for a water heater is provided, which is described by taking the application of the method to the remote controller in fig. 1 as an example, and includes the following steps:
and 202, under the condition that the communication with the water heater through the first communication link fails, establishing a second communication link with the cloud server.
The first communication link may include a UDP (User Datagram Protocol) communication link, and the second communication link may include a TCP (Transmission Control Protocol) communication link.
Specifically, as shown in fig. 3, the remote controller is connected with the water heater, communicates with each other with the UDP mode from first communication link, and the WIFI module of water heater can be connected to cloud ware, realizes remote interaction with APP. After the communication failure is performed on the first communication link (for example, the remote controller cannot reply when sending the control command), the remote controller can additionally establish a second communication link; and the second communication link may comprise a TCP communication link.
In a specific example, as shown in fig. 4, the remote controller may be connected to the water heater through a router, and the link 1 (i.e., the first communication link) in the lan communicates in a UDP manner, and the WIFI module of the water heater may be connected to the cloud server in a TCP long connection manner, so as to realize remote interaction with the APP. The router can be a common home router, and the remote controller can communicate with the router with or without an internet surfing function. When the intelligent terminal is matched with the water heater, the router with the internet surfing capability needs to be adopted.
Further, as shown in fig. 4, after the communication fails in the lan (for example, the remote controller cannot reply by sending a control command), the remote controller additionally establishes a link 2 (i.e., a second communication link); in the application, the remote controller constructs the second communication link and can be realized by utilizing the software capability of the remote controller, namely, the function can be realized without changing any hardware.
The UDP communication (namely the first communication link) has the advantages of high real-time performance and low power consumption, and is suitable for the WIFI remote controller to control the gas water heater; however, the inventor finds that unreliable and easy packet loss are likely to occur if only UDP communication is relied on, and therefore, the application proposes to adopt a compensation measure to improve the problem of low control success rate. The application proposes to establish a second communication link (e.g. a TCP communication link) with the cloud server to establish a compensation mechanism in case of a communication failure with the water heater over the first communication link.
Step 204, transmitting the control instruction to a cloud server through a second communication link; the control instruction is used for instructing the cloud server to transmit the control information obtained by analyzing the control instruction to the water heater.
Specifically, the remote controller additionally establishes a second communication link, uploads the control instruction to the cloud server through the second communication link, and sends the control instruction to the water heater after the control instruction is analyzed by the cloud server. Furthermore, the control success rate can be improved by transmitting the control command to the water heater through the established second communication link in time under the condition that the control of the first communication link fails.
In a specific embodiment, the TCP communication link in the present application may be a TCP short connection link; the control instruction is used for indicating the cloud server to transmit control information obtained by analyzing the control instruction to the water heater through the TCP long connection link;
specifically, taking the remote controller as a WIFI remote controller as an example, the WIFI remote controller additionally establishes a link 2 (a second communication link), further uploads a control instruction to the cloud server in a TCP short connection manner (i.e., a TCP short connection link), and the control instruction is issued to the gas water heater through a pre-established TCP long connection link after being analyzed by the cloud server. According to the method and the system, the control instruction is uploaded to the cloud server in a TCP short connection mode, namely the control instruction is sent once as the short connection for compensation processing, so that power consumption can be reduced, compensation time can be shortened, and user experience can be improved.
It should be noted that, in the present application, the remote controller may also communicate with the cloud server through the long TCP connection, but the long connection setup time is longer.
And step 206, closing the second communication link under the condition that a response message fed back by the water heater based on the control information is received.
Specifically, when the remote controller receives an operation result (i.e., a response message) fed back by the water heater, it confirms that the operation is successful, and then closes the second communication link, thereby implementing the failure compensation control.
In a particular embodiment, the response message may include current status data of the water heater; furthermore, the remote controller can update the local display information of the corresponding water heater under the condition of receiving the current state data of the water heater.
Specifically, the operation result (i.e., the response message) in the present application may refer to the latest state (i.e., the current state data) on the water heater after the control instruction is received. For example, the operation result may include all control functions provided on the remote controller, such as turning on and off the water heater, adjusting the temperature, selecting the mode, calling the function, and the like. And the remote controller displays the latest state after receiving the operation result.
In a specific embodiment, the method may further include the steps of:
and under the condition that the response message fed back by the water heater based on the control information is not received, retransmitting the control instruction to the cloud server through the second communication link until the response message fed back by the water heater is received.
Specifically, if no response message is received, the confirmation operation fails, and then a retransmission mechanism is triggered, and the control information continues to be transmitted by the second communication link, thereby implementing the failure compensation control. That is, if the operation fails, the retransmission mechanism is triggered, and the control information is continuously transmitted through the second communication link, so that the user can be prevented from using hot water under the condition that the control result (success or failure) is not confirmed, and the user experience and water use safety are improved.
According to the remote control method for the water heater, after control fails in the local area network, compensation measures are made through software modification, and the control command is sent to the water heater through the cloud server in a TCP short connection mode, so that the control success rate can be improved. Specifically, the remote controller establishes a second communication link with the cloud server under the condition that the communication with the water heater through the first communication link fails, and completes the transmission of the control instruction with the water heater based on the second communication link, so that failure compensation control is realized. The compensation mode that this application provided can prevent that the user from using hot water under the condition of not confirming the control result (success or not), promotes user experience and water safety.
In one embodiment, as shown in fig. 5, a remote control method for a water heater is provided, which is described by taking the application of the method to the remote controller in fig. 1 as an example, and includes the following steps:
step 502, forming a local area network with the water heater, and establishing a UDP communication link with the cloud server in the local area network; the water heater is successfully distributed in a network through the cloud server and the remote control APP.
Specifically, before the remote controller is paired with the water heater, the APP and the water heater need to be distributed in a network, then the water heater enters an AP (Access Point) mode, the remote controller is connected with an AP hotspot of the water heater to acquire distribution network information and a pairing identifier, and then the remote controller is accessed into a corresponding router to realize the distribution network of the remote controller (namely, a local area network between the remote controller and the water heater is formed), so that the establishment of a link 1 (namely, a first communication link-UDP communication link) is realized.
In a specific embodiment, in the case that the communication with the water heater through the first communication link fails, the step of establishing the second communication link with the cloud server may further include the steps of:
under the condition that a wireless access point of the water heater is monitored, connecting the wireless access point, and acquiring distribution network information and a pairing identifier; the distribution network information comprises router information; the wireless access point is obtained under the condition that the water heater is successfully distributed with the remote control APP through the cloud server and the water heater is triggered to enter the AP mode;
and connecting a router accessed by the water heater in an STA (Station) mode according to the distribution network information to form a local area network, establishing a UDP (user datagram protocol) communication link with the cloud server in the local area network, and completing pairing with the water heater through the pairing identifier.
Specifically, before the WIFI remote controller is matched with the water heater, the APP and the water heater are required to be firstly distributed, then the water heater enters the AP mode, the remote controller is connected with an AP hotspot (namely a wireless access point) of the water heater to acquire distribution network information, and the distribution network information and the water heater are accessed into the same router in the STA mode to form a local area network so as to realize the distribution network of the remote controller, and further establish a UDP communication link in the local area network.
Firstly, a water heater and an APP are distributed to realize a remote control function; then trigger water heater WIFI module and get into the AP mode, trigger the remote controller simultaneously and even access this AP hotspot, acquire router information and pair the sign. The remote controller and the water heater are connected into the same router to form a local area network, a UDP (user Datagram protocol) Server is established by the WIFI module on the water heater, and the remote controller can send a control instruction to the water heater in a UDP Client role to realize a control function.
It should be noted that, after the APP assists the water heater to join in marriage the network successfully, the function of APP remote control water heater can be realized alone. When the remote controller needs to be matched with the remote controller, the AP mode can be triggered by operating the function keys on the panel of the water heater again.
Further, in a specific embodiment, in the case that the communication with the water heater through the first communication link fails, the step of establishing the second communication link with the cloud server may further include the steps of:
under the condition that a wireless access point of the water heater is monitored, connecting the wireless access point to form a local area network, and establishing a UDP communication link with a cloud server in the local area network; the wireless access point is obtained under the condition that the water heater is successfully distributed with the remote control APP through the cloud server and the water heater is triggered to enter the AP mode; the local area network is obtained by accessing a wireless access point through a plurality of remote controllers at present;
and acquiring a pairing identifier, and completing pairing with the water heater through the pairing identifier.
Specifically, an AP hotspot can be directly generated by the water heater, and a plurality of WIFI remote controllers are accessed to the hotspot to form a local area network (all similar devices under the same AP can form a wireless local area network), thereby completing UDP communication in the local area network. Before the remote controller is matched with the water heater, the APP and the water heater are required to be firstly distributed, then the water heater enters an AP mode, and the remote controller is connected with an AP hotspot (namely a wireless access point) of the water heater; and the remote controllers under the same AP can form a local area network, so that the distribution network of the remote controllers is realized, and a first communication link in the local area network is established.
In the application, a plurality of remote controllers can form a local area network with the water heater without a router, and can also directly generate AP hot spots by the water heater, and the plurality of remote controllers are accessed into the hot spots to form the local area network so as to complete UDP communication in the local area network.
Step 504, completing pairing with the water heater;
specifically, after the distribution network is completed, the pairing identifier can be acquired, and the pairing with the water heater can be completed through the pairing identifier. After the local area network is formed, a UDP communication link between the local area network and the cloud server is established, and the local area network and the water heater are paired through the pairing identification.
Step 506, under the condition that the communication with the water heater through the UDP communication link fails, establishing a TCP communication link with the cloud server;
step 508, transmitting the control instruction to a cloud server through a TCP communication link; the control instruction is used for instructing the cloud server to transmit the control information obtained by analyzing the control instruction to the water heater;
and step 510, closing the TCP communication link when a response message fed back by the water heater based on the control information is received, and retransmitting the control instruction to the cloud server through the TCP communication link when a response message fed back by the water heater based on the control information is not received until the response message fed back by the water heater is received.
Specifically, the steps 506 to 510 may be implemented in the related manner discussed in the steps 202 to 206 in the foregoing embodiments, and are not described herein again. According to the method and the device, after the control of the remote controller in the local area network fails, a TCP short connection link is newly established, and a control instruction is issued to the water heater through the cloud server.
To further explain the solution of the present application, the following description is given with reference to a specific example, as shown in fig. 6, taking a remote controller as a WIFI remote controller as an example, first, a network is distributed for a water heater and an APP, so as to implement a remote control function. And then triggering the WIFI module of the water heater to enter an AP mode, triggering a WIFI remote controller to be connected into the AP hotspot, and acquiring router information and a pairing identifier. The WIFI remote controller and the water heater are connected into the same router to form a local area network, a UDP (user Datagram protocol) Server is established by the WIFI module on the water heater, and the WIFI remote controller sends a control instruction to the water heater in a UDP Client role to realize a control function. If the control fails, the control information is sent to the cloud server through the link 2TCP short connection (long connection can also be used), the cloud server is issued to the water heater through the TCP long connection to realize compensation measures, and if the control fails, the steps are repeated. The compensation mode can prevent the user from using hot water under the condition of not confirming the control result (success or failure), and improves the user experience and water use safety.
And the plurality of WIFI remote controllers can also directly generate AP hotspots by the water heater, and the plurality of WIFI remote controllers are accessed into the hotspots to form a local area network so as to complete UDP communication in the local area network.
In addition, the application also provides a matching and control scheme of multiple remote controllers, as shown in fig. 7 and 8, the number of the remote controllers is 3 for example; after the water heater and the APP finish the distribution network, the remote controller 1, the remote controller 2 and the remote controller 3 are respectively paired with the water heater, then the same family router is connected, the communication with the water heater is respectively carried out through a link 1/3/5, and meanwhile, each remote controller can update the state on the water heater according to the control result (namely, the remote control result) of other remote controllers. After control fails, each remote controller sends a control instruction to the cloud server in a TCP short connection mode through a link 2/4/6 respectively, and then the control instruction is forwarded to the water heater, so that compensation control is realized.
It should be noted that, in the present application, each remote controller is respectively connected to the water heater one to one, that is, the water heater has a plurality of remote controllers one to one; the processing logic of the current remote controller for obtaining the remote control result of the other remote controllers may include: the remote controller 1 sends a control instruction to the water heater, after the control is successful, the water heater can automatically synchronize the latest state to each paired remote controller, such as the remote controllers 1, 2 and 3, and all the remote controllers do not need to actively acquire the state of the water heater. And after the remote control result receives the control instruction, the latest state on the water heater. In one example, the remote control result may include all control functions provided on the remote controller, such as turning on and off the water heater, adjusting the temperature, selecting a mode, calling a function, and the like. Namely, the paired remote controllers do not need to actively acquire the state of the water heater, and after the control is successful, the water heater can automatically synchronize the latest state to each paired remote controller. Therefore, the method and the device can simultaneously support the pairing, the control and the state refreshing of a plurality of remote controllers.
It should be understood that although the steps in the flowcharts of fig. 2, 5, 6 and 8 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2, 5, 6, and 8 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performing the sub-steps or stages is not necessarily sequential, but may be performed alternately or alternatingly with other steps or at least some of the sub-steps or stages of other steps.
In one embodiment, as shown in fig. 9, there is provided a remote control device for a water heater, including:
a link establishing module 910, configured to establish a second communication link with the cloud server if communication with the water heater through the first communication link fails; the first communication link comprises a UDP communication link and the second communication link comprises a TCP communication link;
