Description

Technical Field

[0001] This application belongs to the field of Internet of Things (IoT) device control technology, and in particular relates to a dual-network adaptive communication connection method and medium based on mobile cellular and short-range communication, which is applicable to remote control scenarios of mobile devices such as robot dogs, drones, and intelligent robots. Background Technology

[0002] With the rapid development of IoT technology, smart mobile devices (such as robot dogs, inspection robots, and drones) have been widely used in industrial inspection, emergency rescue, and security monitoring. Currently, the mainstream control architecture for these devices adopts a three-tier architecture of "mobile terminal-cloud-device".

[0003] Specifically, existing technical solutions typically include the following components: (1) Mobile terminal (App): As the user interaction entry point, operators send control commands through the application installed on smartphones or tablets. The commands usually include motion control (forward, backward, turn), action execution (taking pictures, robotic arm operation), mode switching, etc.

[0004] (2) Cloud server: As the command forwarding hub, it is responsible for receiving control commands from the App, verifying identity, verifying permissions, parsing commands, and then sending the commands to the target device through the network; at the same time, it is responsible for collecting, storing and forwarding device status data.

[0005] (3) Device side: Intelligent devices such as robot dogs have built-in communication modules (usually 4G / 5G cellular network modules or WiFi modules) to maintain a continuous connection with the cloud, receive and execute control commands from the cloud, and transmit device status (location, power, sensor data, etc.) back to the cloud.

[0006] The above architecture relies on a stable wide area network connection. No direct communication link is established between the App and the device. All control commands and data interactions must be relayed through the cloud server.

[0007] Deficiencies of existing technology Although existing technical solutions can meet basic control requirements in conventional network environments, they have significant technical shortcomings in practical applications, mainly in the following aspects: (1) Control failure problem caused by network dependency The core flaw of existing technical solutions lies in their strong dependence on continuous network connectivity. When the app or device enters areas with weak or no signal coverage, such as elevators, underground tunnels, subway cars, remote mountainous areas, or enclosed storage facilities, the cellular network or WiFi connection will be interrupted or severely weakened, leading to the following consequences: Control commands cannot be issued: Control commands issued by the app cannot reach the device through the cloud, and operators lose the ability to control the equipment in real time; Status information cannot be transmitted: Critical information such as the device's location, operating status, and sensor data cannot be transmitted back to the app, creating an "information black hole"; Task execution is interrupted: Ongoing tasks (such as inspection routes or shooting tasks) may be forced to stop due to communication interruptions, affecting the continuity of operations.

[0008] (2) Lack of communication capabilities in offline scenarios Existing technical solutions lack redundant communication mechanisms to cope with network interruptions. The app and the device communicate only indirectly through the cloud, without establishing any direct short-range communication links (such as Bluetooth, WiFi Direct, etc.). Therefore, even if the app and the device are physically close (such as being in the same elevator), they cannot maintain a basic control connection in the event of a wide area network interruption.

[0009] (3) Lack of communication status awareness and handover mechanism Existing systems lack real-time monitoring capabilities for communication link quality and adaptive switching mechanisms. When devices gradually enter areas with weak signals, the system cannot provide early warnings or automatically switch to backup communication methods. It often only discovers the problem passively after the connection is completely interrupted, missing the opportunity for a smooth transition.

[0010] (4) Limited application in special scenarios The aforementioned defects severely limit the application of smart mobile devices in the following scenarios: Elevator maintenance scenario: When the robot dog enters the elevator with the operator to inspect the equipment, the shielding effect of the elevator car on the signal causes the control to be interrupted; Underground space operation: Scenarios such as tunnels, mines, and underground pipe corridors are themselves in network coverage blind spots; Emergency rescue scenario: Disaster sites such as earthquakes and fires are often accompanied by damage to communication infrastructure, and the control architecture that relies on the cloud fails.

[0011] In summary, existing technical solutions have structural defects in the design of a single "cloud-device" communication path, lacking fault tolerance capabilities to cope with network interruptions and local redundant communication mechanisms. There is an urgent need for a technical solution that can maintain an effective control connection between the App and the device in the event of a wide area network interruption.
