[0081] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0082] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0084] In addition, the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0085] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0086] The embodiment of the present application provides a wireless communication reconnection method, which is applied to a terminal device, which is installed with a client of a control application; the terminal device can be any of the following: a computer device, a laptop computer, a tablet computer, a smart phone, etc. The client of the control application is connected to the robot through a wireless local area network communication.

[0087] The following is an explanation of a wireless communication reconnection method provided in an embodiment of the present application.

[0088] Figure 1 A flow chart of a wireless communication reconnection method provided in an embodiment of the present application Figure 1 ,like Figure 1 As shown, the method may include:

[0089] S101. If it is detected that the wireless local area network is disconnected, a first heartbeat signal is sent to the robot according to a first preset duration.

[0090] In an embodiment of the present application, it is possible to detect whether the wireless local area network between the client of the control application and the robot is stable. If it is detected that the wireless local area network connection is disconnected, a first heartbeat signal is sent to the controller of the robot according to a first preset duration.

[0091] In actual applications, when the wireless LAN restores the connection, the robot's controller can receive the first heartbeat signal and send a response signal corresponding to the first heartbeat signal to the client of the control application; when the wireless LAN is still in a disconnected state, the robot's controller cannot receive the first heartbeat signal, and then cannot send a response signal corresponding to the first heartbeat signal to the client of the control application.

[0092] S102: After the connection is disconnected, if the control application initiates a service request to be transmitted for the robot, the service request to be transmitted is added to a target queue.

[0093] It should be noted that the control application will initiate some service requests to the robot's controller through the wireless LAN to control the robot accordingly. After the wireless LAN is disconnected, some service requests initiated by the client of the control application cannot be sent to the robot's controller in time. These service requests that cannot be sent in time are added to the target queue as pending service requests.

[0094] In some implementations, the service requests to be transmitted may be screened to obtain the screened service requests to be transmitted, and the screened service requests to be transmitted may be added to a target queue.

[0095] S103: If a response signal to the first heartbeat signal sent by the robot is received within the first preset time period, it is confirmed that the wireless local area network reconnection is successful.

[0096] Among them, only when the wireless LAN is restored to connection, can the robot's controller receive the first heartbeat signal and send a response signal corresponding to the first heartbeat signal to the control application through the wireless LAN. Therefore, if the control application receives a response signal to the first heartbeat signal, it can be determined that the wireless LAN is reconnected successfully.

[0097] It is worth noting that if the wireless LAN reconnection is determined to be successful within the first preset time, it means that the time required for the wireless LAN reconnection is short. During this first preset time, the wireless communication reconnection is automatically restored, and the user hardly notices any abnormality in the wireless communication.

[0098] For example, the first preset time length may be 2 seconds. Of course, the first preset time length may also be set according to actual needs, and the embodiment of the present application does not impose any specific limitation on this.

[0099] S104: After the wireless local area network is successfully reconnected, each service request in the target queue is sent to the robot via the wireless local area network.

[0100] In some implementations, after the wireless local area network is successfully reconnected, the service requests in the target queue are sent to the controller of the robot in sequence through the wireless local area network according to the order in which the service requests to be transmitted are added to the target queue.

[0101] Accordingly, the robot controller can sequentially receive each service request in the target queue and perform corresponding service operations according to each service request. This ensures that after the wireless communication is reconnected, the service request initiated by the control application can be responded to and processed in a timely manner.

[0102] In summary, the embodiment of the present application provides a wireless communication reconnection method, which includes: if it is detected that the wireless local area network is disconnected, a first heartbeat signal is sent to the robot according to a first preset duration; after the connection is disconnected, if the control application initiates a service request to be transmitted for the robot, the service request to be transmitted is added to the target queue; if within the first preset duration, a response signal to the first heartbeat signal sent by the robot is received, it is confirmed that the wireless local area network is successfully reconnected; after the wireless local area network is successfully reconnected, each service request in the target queue is sent to the robot through the wireless local area network. After the wireless local area network is detected to be disconnected, regardless of whether the client of the control application initiates a service request, a first heartbeat signal is sent to the robot to try to restore the communication connection with the robot, so that timely reconnection of the wireless local area network can be achieved. Moreover, for the service request initiated by the control application during the disconnection of the wireless local area network, it can be sent to the robot in a timely manner after the wireless local area network is restored and reconnected, so that the robot can be controlled in a timely manner after the wireless communication is reconnected.

[0103] Optionally, there are multiple service requests to be transmitted.

[0104] Figure 2 A flow chart of a wireless communication reconnection method provided in an embodiment of the present application Figure 2 ,like Figure 2 As shown, the process of adding the service request to be transmitted to the target queue in the above S102 may include:

[0105] S201, determining whether there is a robot motion control request among multiple service requests to be transmitted;

[0106] The multiple service requests to be transmitted include at least one type of service request, and the motion control request of the robot is a type of service request, which is used to control the robot to move.

[0107] S202: If yes, filter the motion control request in the multiple service requests to be transmitted to obtain filtered service requests to be transmitted.

[0108] S203: Add the screened service requests to be transmitted to a target queue.

[0109] In some embodiments, if there is a motion control request for the robot, the motion control request among multiple business requests to be transmitted is deleted to obtain filtered business requests to be transmitted, and then the filtered business requests to be transmitted are added to the target queue in sequence according to the initiation time of the filtered business requests to be transmitted.

[0110] Of course, the motion control requests in the multiple service requests to be transmitted may also be marked to ensure that the marked motion control requests are not added to the target queue.

[0111] In actual applications, the service requests in the target queue are sent to the robot only after the wireless communication is reconnected, and there is a certain delay. If the motion control request is added to the target queue, it will cause a delay in controlling the robot's movement, which will pose a safety hazard. The embodiment of the present application filters the motion control request to avoid this safety hazard.

[0112] Optionally, Figure 3 A flow chart of a wireless communication reconnection method provided in an embodiment of the present application Figure 3 ,like Figure 3 As shown, the method may also include:

[0113] S301: If no response signal to the first heartbeat signal sent by the robot is received within a first preset time period, it is determined that the wireless LAN reconnection has temporarily failed.

[0114] If the wireless local area network reconnection still cannot be restored within the first preset time, it indicates that the wireless communication connection is disconnected. At this time, the user needs to be informed of the current wireless local area network status to improve the user experience.

[0115] S302: Displaying a reconnection prompt message for the wireless local area network in a first pop-up window.

[0116] Figure 4 A schematic diagram of displaying a first pop-up window provided in an embodiment of the present application is shown as follows: Figure 4 As shown, a first pop-up window is displayed, and a reconnection prompt message for the wireless local area network is displayed in the first pop-up window. For example, the reconnection prompt message may be "Network abnormality, reconnecting, please wait patiently".

[0117] Optionally, Figure 5 A flow chart of a wireless communication reconnection method provided in an embodiment of the present application Figure 4 ,like Figure 5 As shown, in S301, if no response signal to the heartbeat signal sent by the robot is received within the first preset time, then after confirming that the wireless local area network reconnection has temporarily failed, the method may further include:

[0118] S401. Send a second heartbeat signal to the robot according to a second preset duration.

[0119] In the embodiment of the present application, sending a first heartbeat signal to the robot within a first preset time period belongs to the first stage of reconnection, and after the first stage of reconnection fails, sending a second heartbeat signal to the robot within a second preset time period belongs to the second stage of reconnection.

[0120] S402: If a response signal to the second heartbeat signal sent by the robot is received within the second preset time period, it is confirmed that the wireless local area network reconnection is successful.

[0121] It should be noted that the control application sends the second heartbeat signal to the robot controller, and after receiving the second heartbeat signal, the robot controller sends a response signal to the control application for the second heartbeat signal. The entire process requires transmission of the wireless local area network. Therefore, when the control application can receive the response signal to the second heartbeat signal, it can be said that the wireless local area network reconnection is successful.

[0122] S403: Cancel displaying the first pop-up window.

[0123] Among them, the first pop-up window can be automatically hidden.

[0124] S404: Send each service request in the target queue to the robot via the wireless local area network.

[0125] It should be noted that the process of S404 is similar to the process of S104, and will not be described in detail here.

[0126] It should be noted that after the wireless LAN connection is disconnected, the robot controller will still maintain a request receiving state for a period of time. If the robot controller does not receive a new request, it will consider the connection with the control application to be disconnected. At this stage, the response to the second heartbeat signal will determine the subsequent actions. If the robot controller is still in a waiting state and responds to the second heartbeat signal normally, it indicates that the wireless LAN connection has been restored. The control application will automatically hide the first pop-up window and resend the service request in the target queue.

[0127] Optionally, Figure 6 A flow chart of a wireless communication reconnection method provided in an embodiment of the present application Figure 5 ,like Figure 6 As shown, the method may also include:

[0128] S501. Display a cancel reconnection control in the first pop-up window.

[0129] like Figure 4 As shown, a cancel reconnection control is also displayed in the first pop-up window.

[0130] S502: within a second preset time period, in response to a selection operation for canceling the reconnection control, stop sending a second heartbeat signal to the robot.

[0131] Wherein, while stopping sending the second heartbeat signal to the controller of the robot, the service requests in the target queue can also be cleared.

[0132] In the embodiment of the present application, the selection operation for canceling the reconnection control can be a touch operation for canceling the reconnection control, of course, it can also be an operation input by an external device connected to the terminal device, or it can be an operation input by other methods, and the embodiment of the present application does not specifically limit this. Among them, the external device can be a mouse and / or a keyboard.

[0133] Optionally, Figure 7 A flow chart of a wireless communication reconnection method provided in an embodiment of the present application Figure 6 ,like Figure 7 As shown, the method may also include:

[0134] S601: If no response signal to the second heartbeat signal sent by the robot is received within a second preset time period, it is determined that the wireless LAN reconnection has failed, and the robot's logout operation is executed.

[0135] It should be noted that if the wireless LAN is still disconnected within the second preset time period, the control application cannot send the second heartbeat signal to the robot's controller. The robot's controller does not receive any signal sent by the control application within the second preset time period, and will end the receiving state and execute the logout operation.

[0136] Correspondingly, if the control application does not receive a response signal to the second heartbeat signal within the second preset time period, indicating that the reconnection cannot be restored within a long period of time, a logout operation is performed.

[0137] S602: Stop sending the second heartbeat signal to the robot.

[0138] S603: Clear all service requests in the target queue.

[0139] Optionally, Figure 8 A flow chart of a wireless communication reconnection method provided in an embodiment of the present application Figure 7 ,like Figure 8 As shown, in the above S601, if no response signal to the second heartbeat signal sent by the robot is received, it is confirmed that the wireless local area network reconnection fails, and after the process of executing the robot's logout operation, the method may further include:

[0140] S701. Switch the first pop-up window to the second pop-up window.

[0141] The first pop-up window can be canceled and the second pop-up window can be displayed. When the second pop-up window appears, it means that the second heartbeat signal is no longer sent to the robot, and automatic reconnection is no longer attempted, and the logic of automatic reconnection has been exited.

[0142] S702. The second pop-up window displays reconnection failure information for the wireless local area network and a reconnection control.

[0143] Fig. 9 A schematic diagram of displaying a second pop-up window provided in an embodiment of the present application is shown as follows: Fig. 9 As shown, the second pop-up window displays reconnection failure information and reconnection controls. For example, the reconnection failure information may be "Reconnection failed, please reconnect".

[0144] In addition, if Fig. 9 As shown, the second pop-up window may also include a cancel control. In response to a selection operation on the cancel control, the second pop-up window is hidden and displayed, and the control application is still in a logged out state. When the user wants to give up logging in, the cancel control can be selected.

[0145] S703. In response to the selection operation for the reconnection control, the robot login operation is performed according to the pre-stored account information.

[0146] In the embodiment of the present application, when the second pop-up window is displayed, the user has logged out. After the user determines that the wireless LAN is restored, the user can enter a selection operation for the reconnection control, and the control application responds to the selection operation for the reconnection control and automatically executes the robot login operation according to the pre-stored account information. Here, the user does not need to re-enter the account password.

[0147] Optionally, Fig.10 A flow chart of a wireless communication reconnection method provided in an embodiment of the present application Figure 8 ,like Fig.10 As shown, the process of sending the first heartbeat signal to the robot according to the first preset duration in the above S101 may include:

[0148] S801. Send a first heartbeat signal to the robot within a first preset time period.

[0149] Among them, within the first preset time period, the first heartbeat signal can be sent based on a preset heartbeat signal sending frequency.

[0150] S802: Adjust the duration of the first preset duration and the frequency of sending the heartbeat signal according to the error information fed back by the communication protocol corresponding to the wireless local area network.

[0151] During the process of the control application sending the first heartbeat signal to the robot, the communication protocol corresponding to the wireless local area network will send an error message to the control application, and the control application will dynamically adjust the sending strategy of the first heartbeat signal based on the error message, wherein the process of dynamically adjusting the sending strategy may include adjusting the duration of the first preset duration and the frequency of sending the heartbeat signal.

[0152] In some embodiments, the error message indicates that the protocol stack reports a timeout error, and the control application will reduce the frequency of sending the heartbeat signal and shorten the duration of the first preset duration. The error message may be "Deadline Exceeded".

[0153] In other embodiments, the error message is "Stream removed" (usually not a standard error message, it may be a custom error generated by an application or framework when processing the stream), or the error message is "Failed to connect to all addresses" (usually indicating that the client attempted to connect to a service but could not connect to all attempted addresses), then the frequency of sending heartbeat signals is increased and the duration of the first preset duration is extended.

[0154] In practical applications, the wireless local area network may be a WiFi (Wireless Fidelity, wireless network).

[0155] S803. Continue to send the first heartbeat signal to the robot according to the adjusted first preset duration and the adjusted heartbeat signal sending frequency.

[0156] Among them, continuing to send the first heartbeat signal to the robot according to the dynamically adjusted sending strategy can maximize the success rate of wireless communication reconnection.

[0157] It should be noted that the error message may be "software caused connection abort" to indicate that the user actively disconnects the wireless LAN connection, and the control application displays the second pop-up window; or the error message may be "Safe handle has been closed" to control the application to display the second pop-up window. When the second pop-up window is displayed, the heartbeat signal is stopped from being sent.

[0158] Similarly, within the second preset time period, a second heartbeat signal is sent to the robot, and the duration of the first preset time period and the frequency of sending the heartbeat signal can be adjusted according to the error information fed back by the communication protocol corresponding to the wireless local area network; the second heartbeat signal continues to be sent to the robot according to the adjusted second preset time period and the adjusted frequency of sending the heartbeat signal.

[0159] In the embodiment of the present application, since the robot's default IP (Internet Protocol) address and default password are unified, in order to ensure the security of the connection, the control application and the robot's controller will perform a robot MAC (Media Access Control Address) address check during the entire reconnection process to prevent problems during the connection process.

[0160] In summary, the embodiment of the present application provides a wireless communication reconnection method. After detecting that the wireless local area network is disconnected, regardless of whether the client of the control application initiates a service request, a first heartbeat signal is sent to the robot to try to restore the communication connection with the robot, so that timely reconnection of the wireless local area network can be achieved. Moreover, for the service request initiated by the control application during the period when the wireless local area network connection is disconnected, it can be sent to the robot in time after the wireless local area network is restored and reconnected, so that the robot can be controlled in time after the wireless communication is reconnected.

[0161] In addition, filtering the motion control requests among the multiple service requests to be transmitted can improve the security of the robot control after the wireless local area network is reconnected.

[0162] Moreover, the network status and robot feedback are monitored in real time, and the sending strategy is adjusted dynamically to maximize the success rate of connection. At the same time, the control application will provide clear feedback to the user through the interface, so that the user has a clear understanding of the current network status and operation results, so as to maintain the continuity and reliability of operation even when the network is unstable. It can minimize user intervention, improve the stability and security of the system, optimize resource consumption, and enhance user experience. It not only improves the success rate of reconnection, but also ensures adaptability and flexibility in various network environments, providing users with a seamless and safe control experience.
