[0075] With the increasing application of robots in special scenarios such as factory operations, they have become an important tool for improving production efficiency and reducing labor costs.

[0076] However, at the same time, due to the vast working space, the network connection between the robot and auxiliary equipment may often be disconnected due to uncertain factors such as position movement and increase of obstacles. This not only increases the operator's workload and reduces the user experience, but may even cause the robot to lose control during the operation process, causing potential harm and risks to the working environment and related personnel.

[0077] In view of this, the present disclosure provides a connection method, an apparatus, a computer device and a storage medium.

[0078] Below Figure 1 As an example, exemplary application scenarios of some embodiments of the present disclosure are introduced. Among them, the auxiliary device can be an electronic device such as a mobile phone, a laptop computer, etc. that has a LAN connection capability and a personal LAN connection capability, and the robot can be a robot dog, a cleaning robot, etc. that has a LAN connection capability and a personal LAN connection capability. Generally speaking, robots used for operations do not have specially designed human-computer interaction functions, so for non-pre-stored network information, auxiliary devices such as mobile phones are usually required to assist the robot in connecting.

[0079] Among them, the Local Area Network (LAN) can be initiated by devices such as routers or switches, while the Personal Area Network (PAN) refers to a communication network composed of computing devices (such as computers, phones, robots, digital cameras, etc.) within a personal range (for example, within tens of meters). PAN can be used to exchange data between these devices, and can also be used to connect to high-level networks or the Internet. PAN can be in wired form, such as the Universal Serial Bus USB or Firewire (IEEE1394) bus; it can also be in wireless form, such as infrared (IrDA) or Bluetooth. A personal area network that uses wireless technology is called a wireless personal area network (WPAN). It is worth noting that personal area network and local area network are two different concepts and there is no complete inclusion relationship.

[0080] In special scenarios such as factory operations, robots are often needed to reach areas that are inconvenient for operators to reach (such as areas with special terrain or harsh environments) and perform operations, or to use robots to simplify the difficulty of operators' operations. A common requirement is that the robot and the operator (user) are kept at a close distance (for example, within tens of meters), and the auxiliary equipment held by the operator (or carried with him) needs to collect large-scale data sent back by the robot, such as the robot's real-time field of view, status parameters, and instruction receipts, etc., and also needs to issue new instructions to the robot. These large-scale data are usually not borne by personal LAN media such as Bluetooth. Considering factors such as cost and feasibility, these large-scale data are usually transmitted based on LAN. However, when a user controls a robot with handheld auxiliary equipment, the operation often involves a wider activity area (i.e., the position will change over a larger range), and the local area network is usually provided by a router or switch in a fixed position. This leads to frequent disconnections between the robot and the auxiliary equipment during the operation. This problem is particularly prominent in scenarios such as factories and outdoor test areas. In order to ensure the controllability of the robot and the adaptability of the operation process to the scenario, in actual applications, the distance between the operator and the robot is usually kept close.

[0081] Next, the embodiments of the present disclosure are described in detail from two execution sides: the robot and the auxiliary equipment.

[0082] The first aspect of the present disclosure provides a connection method that can be applied to a robot. Figure 2 , which comprises the following steps:

[0083] Step S201, in response to the current connection quality between the robot and the local area network LAN being less than a first threshold, a first signal is sent to an auxiliary device so that the auxiliary device sends at least one available LAN to the robot based on a personal area network PAN, wherein the connection quality between the available LAN and the auxiliary device is greater than or equal to a second threshold.

[0084] The first threshold and the second threshold can respectively represent the minimum acceptable limit of the connection quality between the robot and the auxiliary device and the local area network, that is, when the connection quality between the robot and the local area network is less than the first threshold or the connection quality between the auxiliary device and the local area network is less than the second threshold, it can be considered that the data transmission quality of the robot and the auxiliary device based on the local area network will be greatly affected, or even reach an unusable state; in addition, the first threshold and the second threshold can also be set by the user based on personal experience or the performance parameters of the device itself, and this disclosure does not limit this. The connection quality is an indicator or parameter used to quantify and describe the performance and reliability of the communication connection between different terminals. In the embodiments of the present disclosure, the measurement of connection quality can be based on multiple factors, including but not limited to the following aspects: signal strength, usually expressed in the form of a signal received strength indicator (RSSI), a higher signal strength usually indicates a better connection quality; signal-to-noise ratio (SNR), a measure of the ratio between signal and noise, a higher signal-to-noise ratio usually indicates a better connection quality; bit error rate (BER), a measure of the proportion of erroneous bits occurring in data transmission, a lower bit error rate usually indicates a better connection quality; delay, a measure of the time delay required for data to travel from the sender to the receiver, a lower delay usually indicates a better connection quality; bandwidth, a measure of the data transmission rate available in the connection, a higher bandwidth usually indicates a better connection quality.

[0085] It should be understood that in the embodiments of the present disclosure, the larger the value of the connection quality, the better the connection quality (of course, the above relationship can also be reversed, and the judgment condition can be reversed accordingly). In actual application, the connection quality provided by the present disclosure can be reflected by any indicator or parameter, including an indicator or parameter whose larger value indicates a larger connection quality, and an indicator or parameter whose smaller value indicates a larger connection quality. The specific calculation method can also be set according to actual conditions, for example, different weights are set for the above measurement factors to comprehensively calculate the connection quality, and the present disclosure does not limit it.

[0086] Since the first signal sent by the auxiliary device can actually only be used to characterize that the current network condition of the robot is poor, its information volume can be compressed to a lower level, and it may still be sent when the LAN connection is poor (that is, the connection quality is less than the first threshold or the second threshold); in addition, when the connection quality between the robot and the LAN is less than the first threshold, the robot can send the first signal to the auxiliary device based on the PAN to ensure that the first signal can be received by the auxiliary device; or, the robot can first try to send the first signal based on the LAN connection, and if no receipt is received from the auxiliary device within a preset time, the first signal can be sent based on the PAN. The present disclosure does not limit this.

[0087] Step S202: connecting to an available LAN among the at least one available LAN, wherein the connection quality between the robot and the connected available LAN is greater than or equal to the first threshold.

[0088] After the robot receives at least one available LAN, illustratively, it can connect to the available LANs in the at least one available LAN one by one until the connection quality between the robot and the available LAN is greater than or equal to the first threshold. This method can more quickly find a LAN whose connection quality with the robot and the auxiliary device is in an acceptable state, and quickly restore the LAN connection between the robot and the auxiliary device; illustratively, it can connect to the available LAN with the highest connection quality between the robot in the at least one available LAN. In other words, it can obtain the connection quality between at least one available LAN and the robot, and select the available LAN with the best connection quality to connect, so as to obtain the best connection quality. Of course, the above two schemes can also be combined, for example, first traverse the available LANs in the at least one available LAN, and connect to the LAN when the connection quality between the available LAN and the available LAN is greater than or equal to the first threshold, and continue the traversal action, and then switch to the LAN with better connection quality when a LAN with better connection quality is obtained, so as to take into account both connection speed and connection quality.

[0089] It should be understood that the above "one by one" is only a description of the step logic, rather than a limitation on the specific execution actions. For example, when the robot has multiple network adapters or other configurations that can achieve the same function, it can actually obtain the connection quality of multiple LANs at the same time, but logically, it is still a process of traversing the available LANs in at least one available LAN one by one.

[0090] Furthermore, in order to obtain the best network connection quality between the robot and the auxiliary device, the method may further include sending a second signal to the auxiliary device so that the auxiliary device is connected to the LAN consistent with the robot. For example, after connecting to a certain LAN, the robot may send the user name of the certain LAN to the auxiliary device based on the PAN so that the auxiliary device is connected to the certain LAN.

[0091] In the disclosed embodiment, in response to the current connection quality between the robot and the local area network LAN being less than a first threshold, the robot sends a first signal to the auxiliary device, so that the auxiliary device sends at least one available LAN whose connection quality with the auxiliary device is greater than or equal to a second threshold based on the personal local area network PAN to the robot; next, the robot can connect to an available LAN among the at least one available LAN, and connect the robot to the LAN whose connection quality is greater than or equal to the first threshold. Since the local area network (LAN) is often provided by a router or switch at a fixed location, and the PAN can usually be directly provided by the auxiliary device or robot to build a point-to-point connection (furthermore, PAN has the characteristics of low power consumption, low bandwidth, and stable connection within a short distance), generally speaking, when the robot or auxiliary device is displaced, PAN can provide a more stable connection than LAN, and may only be affected by the relative distance between the robot and the auxiliary device. This advantage is particularly evident in the above-mentioned special scenarios (such as factory operations); the above-mentioned method avoids the disconnection of the LAN connection between the robot and the auxiliary device by notifying the auxiliary device when the quality of the robot's LAN connection is poor, and enables the auxiliary device to send the LAN connection information to the robot based on the PAN, thereby ensuring the availability of a large-scale data transmission channel between the robot and the auxiliary device while taking into account cost and power consumption.

[0092] In some embodiments of the present disclosure, the robot may store a LAN list, and the LAN list may store connection information of at least one LAN. In response to the current connection quality between the robot and the local area network LAN being less than a first threshold, sending a first signal to the auxiliary device includes:

[0093] In response to the current connection quality between the robot and the local area network (LAN) being less than a first threshold, determining whether there is a LAN in a LAN list whose connection quality with the robot is greater than or equal to the first threshold, wherein the LAN list includes at least one LAN;

[0094] In response to the presence of a LAN in the LAN list whose connection quality with the robot is greater than or equal to the first threshold, connecting the LAN whose connection quality with the robot is greater than or equal to the first threshold; or,

[0095] In response to the LAN list not having a LAN with a connection quality greater than or equal to the first threshold with the robot, a first signal is sent to an auxiliary device so that the auxiliary device sends at least one available LAN not in the LAN list to the robot.

[0096] In other words, the robot can automatically switch among the LANs stored in the LAN list to ensure that the connection quality between the robot and the LAN is greater than or equal to the first threshold. The LAN list can store LAN connection information (i.e., information used to connect to the corresponding LAN), such as IP (Internet Protocol) address, network name, password, etc. Based on this, the robot can automatically adapt to changes in the network connection status, and minimize data exchange between the robot and auxiliary equipment, thereby reducing network bandwidth pressure.

[0097] Furthermore, the method may also include:

[0098] The LAN list is updated according to the at least one available LAN that is not present in the LAN list.

[0099] Specifically, the auxiliary device may try to obtain an available LAN at a preset frequency, or may obtain an available LAN in response to a first signal sent by the robot, and then send a third signal to the auxiliary device when an available LAN that does not exist in the LAN list is obtained. The third signal may include the available LAN that does not exist in the LAN list, or the complete LAN list may be sent to the auxiliary device, and the present disclosure does not limit this. Based on this, the robot can store the received available LAN and automatically connect to the network when accessing the network next time, further reducing the amount of data transmitted between the robot and the auxiliary device and reducing the pressure on the network bandwidth.

[0100] It should be understood that in order to enable both the auxiliary device and the robot to access the LAN list respectively, the LAN list can be stored on the auxiliary device and the robot respectively, and a synchronization step of the LAN list can be added before or during the execution of the method, that is, the union of the LAN lists stored in the auxiliary device and the robot is taken, or the LAN list stored in one of the auxiliary device and the robot is taken, and the taken content is stored in the auxiliary device and the robot; or the LAN list can also be stored in a device that can be accessed by both the auxiliary device and the robot. Similarly, in the present disclosure, since the LAN list represents the same meaning, the LAN list stored on both sides is not distinguished, but this does not strictly limit the storage location and existence form of the LAN list.

[0101] The second aspect of the present disclosure provides a connection method that can be applied to the auxiliary device side. Figure 3 , the method may include:

[0102] Step S301, in response to receiving a first signal, at least one available LAN is sent to the robot based on a personal area network PAN, so that the robot connects to an available LAN among the at least one available LAN, wherein the connection quality between the robot and the connected available LAN is greater than or equal to the first threshold, the first signal is sent by the robot in response to the current connection quality between the robot and the local area network LAN being less than the first threshold, and the connection quality between the available LAN and the auxiliary device is greater than or equal to a second threshold.

[0103] For explanations of relevant concepts and details, please refer to the description of the corresponding part in the first aspect, which will not be repeated here. In the above steps, the auxiliary device can search for nearby local area networks, and send the local area networks whose connection quality with the auxiliary device is greater than a second threshold as at least one available local area network to the robot.

[0104] Regarding the conditions and specific details of the auxiliary device acquiring at least one available LAN, exemplarily, the step of (in response to receiving the first signal) sending at least one available LAN to the robot based on the personal area network PAN so that the robot connects to an available LAN in the at least one available LAN may include:

[0105] In response to obtaining at least one available LAN that does not exist in the LAN list, the at least one available LAN that does not exist in the LAN list is sent to the robot based on PAN so that the robot connects to the at least one available LAN that does not exist in the LAN list, and updates the LAN list according to the at least one available LAN that does not exist in the LAN list, wherein the LAN list includes at least one LAN.

[0106] As another example, the method may further include:

[0107] In response to the time interval between the current moment and the last time the available LAN was obtained reaching a time threshold, obtaining the available LAN;

[0108] In response to acquiring at least one available LAN that does not exist in the LAN list, the LAN list is updated according to the at least one available LAN, and a third signal is sent to the robot so that the robot updates the LAN list based on the third signal, wherein the LAN list includes at least one LAN, and the third signal is used to instruct the robot to update the LAN list according to the at least one available LAN that does not exist in the LAN list.

[0109] In other words, the robot can automatically switch among the LANs stored in the LAN list to ensure that the connection quality between the robot and the LAN is greater than or equal to the first threshold. The LAN list can store LAN connection information (i.e., information used to connect to the corresponding LAN), such as IP (Internet Protocol) address, network name, password, etc. Based on this, the robot can automatically adapt to changes in the network connection status, and minimize data exchange between the robot and auxiliary equipment, thereby reducing network bandwidth pressure.

[0110] In the above two exemplary embodiments, the available LAN can also be obtained in response to the first signal sent by the robot, and the auxiliary device can try to obtain the available LAN at a preset frequency, and then send a third signal to the auxiliary device when an available LAN that does not exist in the LAN list is obtained. The third signal can include the available LAN that does not exist in the LAN list, or the complete LAN list can be sent to the auxiliary device, and the present disclosure does not limit this. Based on this, the robot can store the received available LAN and automatically connect to the network when accessing the network next time, further reducing the amount of data transmitted between the robot and the auxiliary device and reducing the pressure on the network bandwidth. It should be understood that in order to enable the auxiliary device and the robot to access the LAN list respectively, the LAN list can be stored on the auxiliary device and the robot respectively, and a synchronization step of the LAN list can be added before or during the execution of the method, that is, the union of the LAN lists stored in the auxiliary device and the robot is taken, or the LAN list stored in one of the auxiliary device and the robot is taken, and the taken content is stored in the auxiliary device and the robot; or the LAN list can also be stored in a device that can be accessed by both the auxiliary device and the robot.

[0111] Furthermore, in order to obtain the best network connection quality between the robot and the auxiliary device, the method may further include receiving a second signal and connecting to a LAN indicated by the second signal, wherein the second signal is used to connect the auxiliary device to a LAN consistent with the robot. For example, after connecting to a certain LAN, the robot may send the user name of the certain LAN to the auxiliary device based on the PAN, so that the auxiliary device is connected to the certain LAN.

[0112] In addition, the auxiliary device may also provide an interactive interface to the user, receive a LAN and a corresponding password selected by the user based on the interactive interface, and save the connection information of this LAN in the LAN list, or send it to the robot. Optionally, when the auxiliary device finds an available LAN that does not exist in the LAN list, it may prompt the user with the available LAN and receive the password entered by the user, thereby saving the connection information of this LAN in the LAN list, or sending it to the robot.

[0113] In the disclosed embodiment, in response to the current connection quality between the robot and the local area network LAN being less than a first threshold, the robot sends a first signal to the auxiliary device, so that the auxiliary device sends at least one available LAN whose connection quality with the auxiliary device is greater than or equal to a second threshold based on the personal local area network PAN to the robot; next, the robot can connect to an available LAN among the at least one available LAN, and connect the robot to the LAN whose connection quality is greater than or equal to the first threshold. Since the local area network (LAN) is often provided by a router or switch at a fixed location, and the PAN can usually be directly provided by the auxiliary device or robot to build a point-to-point connection (furthermore, PAN has the characteristics of low power consumption, low bandwidth, and stable connection within a short distance), generally speaking, when the robot or auxiliary device is displaced, PAN can provide a more stable connection than LAN, and may only be affected by the relative distance between the robot and the auxiliary device. This advantage is particularly evident in the above-mentioned special scenarios (such as factory operations); the above-mentioned method avoids the disconnection of the LAN connection between the robot and the auxiliary device by notifying the auxiliary device when the quality of the robot's LAN connection is poor, and enables the auxiliary device to send the LAN connection information to the robot based on the PAN, thereby ensuring the availability of a large-scale data transmission channel between the robot and the auxiliary device while taking into account cost and power consumption.

[0114] Next, combine Figure 4 The architecture diagram shown and Figure 5 The selection branch diagram shown further illustrates at least one of the above-mentioned embodiments.

[0115] See also Figure 4 The auxiliary device may have a Bluetooth master module, a LAN search module, and a LAN list storage module; the robot may have a network anomaly detection module, a Bluetooth slave module, a network switching module, and a LAN list storage module. Among them, the Bluetooth slave refers to a Bluetooth module that broadcasts and passively waits for pairing during the pairing and connection process, and the Bluetooth master refers to a module that detects the broadcast sent by the Bluetooth slave during the pairing and connection process and actively sends a handshake signal for pairing and connection.

[0116] See also Figure 5Taking the aforementioned factory operation scenario as an example, when the operation starts, the operator can enable the robot to send a Bluetooth broadcast and control the auxiliary device to establish a Bluetooth connection (or other PAN connection) with the robot; after the connection is successfully established, the auxiliary device can scan nearby available LANs and synchronize the LAN list between the robot and the auxiliary device. In addition, the auxiliary device can also prompt the user with an interactive interface to facilitate the user to select and enter the corresponding password from the currently searchable LANs.

[0117] Next, when the robot's LAN connection quality is less than a first threshold, the robot may send a first signal to the auxiliary device to enable the auxiliary device to scan for available LANs, add the newly scanned available LANs to the LAN list, and synchronize them to the robot. After receiving at least one available LAN, the robot may select an available network and connect to it, so that the connection quality between the robot and the LAN is greater than or equal to the first threshold, and at the same time, it can ensure that the connection quality between the LAN and the auxiliary device is greater than or equal to the second threshold. After the robot is connected to an available LAN, a second notification is sent to the auxiliary device to connect the auxiliary device to the same LAN as the robot, thereby achieving a seamless switching of the LAN connection between the robot and the auxiliary device and avoiding the disconnection of the LAN.
