Description

Technical Field

[0001] The present invention relates to the technical field of network communications, and more particularly to a remote debugging and access system for intelligent portable devices. Background Art

[0002] With the rapid development of science and technology, smart portable devices are increasingly used in various fields, from industrial production to daily consumption, from smart homes to medical equipment, and their importance continues to increase. Remote debugging and access technology has become a key link in the research and development, production, and maintenance of smart portable devices.

[0003] Traditional debugging and access methods present numerous challenges. First, serial port debugging requires the use of specialized cables for physical connection when connecting to industrial equipment supporting the RS232 protocol. This cumbersome process, coupled with cable length limitations, severely limits the scope of debugging. If equipment is geographically dispersed, engineers must conduct on-site debugging in person, a time-consuming and labor-intensive process. Geographical constraints also lead to inefficient debugging, severely impacting project progress.

[0004] When it comes to network debugging, existing technologies present difficulties in achieving network sharing. Sharing the debugging box's WiFi network to wired devices is complex, requiring additional network equipment and a complicated configuration process, making it difficult for average users and those with limited technical skills to complete. Furthermore, in an offline environment, initial device configuration is extremely inconvenient, making it difficult to quickly and flexibly establish a network connection, impacting the device's normal use.

[0005] Software compatibility and remote access also present significant challenges. A lack of unified standards across different client software and operating systems leads to poor compatibility. For example, some debugging software only supports specific operating systems and cannot be used across multiple platforms, limiting user choice. Furthermore, due to the limitations of the intranet environment, remote access is difficult to implement, making it difficult to meet user needs for debugging and accessing devices anytime, anywhere.

[0006] These problems have seriously restricted the development and application of smart portable devices. There is an urgent need for a system with high integration, easy operation, strong compatibility and efficient remote debugging and access to solve these problems, thereby promoting the in-depth application of smart portable devices in more fields.

[0051] The remote access module maps the control port (TCP:7575) of the main control development board to the Internet through a reverse proxy tool, and the client remotely accesses the debugging function through the proxy server IP and port.

[0052] The reverse proxy tool is an open source NPS tool used to penetrate the intranet and establish a remote connection tunnel.

[0053] The power management module uses the IP5310 chip, which integrates battery charging and power supply management functions to support continuous operation in mobile scenarios.

[0054] In specific implementation, hardware implementation:

[0060] Install VirtualHere or USB / IPClient software on the client to discover the device through the LAN and map it to the local computer.

[0061] Bluetooth network configuration implements WiFi parameter configuration through SSH script or WebBluetoothAPI;

[0062] Use the NPS tool to establish a reverse proxy and map the local port to the public network to achieve remote access.

[0063] Technical Principle

[0064] USBIP protocol: encapsulates the control instructions of USB devices into IP data packets, transmits them through the local area network or the Internet, and realizes virtual access of remote devices;

[0065] Bluetooth network configuration: Use Bluetooth low energy features to establish a temporary network channel and configure the WiFi connection of the main control development board through scripts or APIs;

[0066] Reverse proxy: Use the NPS tool to penetrate the intranet restrictions, expose the local service port to the public network, and the client can achieve remote control through the proxy server.

[0070] Remote and efficient: cross-regional device debugging is achieved through USBIP protocol and reverse proxy, reducing on-site deployment costs;

[0071] Flexible networking: Bluetooth and WiFi hybrid network configuration mode, adapting to the initial configuration of devices without network environment;

[0072] Strong compatibility: compatible with VirtualHere, USB / IPClient and other software, supporting Windows and Linux multi-platform clients.

[0073] Specifically, the hardware part: as attached Figure 1 and Figure 3 The intelligent portable device provided by the present invention is composed of a battery, an integrated PCB circuit board, a power management module, an orangepi development board, an FPCB antenna, an FPC interconnection line, and a shell.

[0074] Software part: system hardware identification description

[0075] 1. OrangePi development board runs Ubuntu Linux;

[0076] 2. Through the hardware design, you can see two USB devices in the system;

[0077] 3. They are CH340 serial port device and USB network card respectively;

[0078] 4. There is also a network card that comes with the system.

[0079] Use the USBIP protocol to map the USB device of the debugging box to the client computer over the network.

[0080] The USBIP (USB over IP) protocol allows remote access to USB devices over a network. It encapsulates USB device control and data transmission into network packets, enabling the sharing of local USB devices with remote computers. Specifically, USBIP encapsulates USB device operations into IP packets, transmits them over the network to the remote host, which then forwards the requests to the connected USB device using the USBIP protocol.

[0081] The working principle of USBIP protocol can be briefly described as the following steps:

[0082] 1. Device Sharing: On the local host, share one or more USB devices with the remote computer through the USBIP protocol. The shared devices will be mapped as network resources.

[0083] 2. Device access: The remote computer requests access to the shared USB device through the USBIP protocol.

[0084] 3. Data transfer: Data is transferred over the network, and the remote computer sends USB requests to the local computer and receives responses, operating just like a locally connected device.

[0085] 4. Virtualized interface: The remote device interacts with the local device through the USBIP protocol, and the underlying layer interacts by transmitting USB data packets over the network.

[0086] This technology is often used to use USB devices on remote servers. Through USBIP, users can access USB printers, cameras, storage devices, etc.

[0087] As attached Figure 4 As shown, the development board and the computer are connected to the same local area network (connected to the same WiFi). Open the client software and select the corresponding device to be mapped to the local computer. The effect achieved is equivalent to connecting the debug cable or USB network card directly to the computer for use.

[0088] Bluetooth network configuration

[0089] The UsbIP protocol is an IP-based USB mapping, so the development board and the client computer need to communicate over the network.

[0090] How to establish a network connection between the computer and the development board:

[0091] 1. Use the mobile phone's hotspot to connect the computer and the development board to the WiFi transmitted by the mobile phone's hotspot. This way, the development board and the computer can be in the same local area network. As long as you open the client software, the software will actively scan the local area network devices and automatically connect to the development board, and then you can map and use it.

[0092] 2. Use the computer's hotspot to connect the development board to the WiFi hotspot emitted by the computer. You can also make the development board and the computer in the same local area network. The software actively scans the local area network devices, automatically connects to the development board, and maps them for use.

[0093] Network configuration via Bluetooth Personal Area Network SSH mode

[0094] As attached Figure 5 As shown in the figure, the Bluetooth network sharing function of the development board is enabled through configuration. The computer connects to the Bluetooth of the development board and joins the shared network of the development board. Then, the bat script SSH is used to connect to the development board. After the connection is logged in, the network configuration shell script on the development board is automatically executed to configure the WiFi connection in a wizard-like manner.

[0095] Connect to Bluetooth on the web page through WebBluetoothAPI to achieve network configuration

[0096] The WebBluetooth API is a set of JavaScript APIs for communicating with Bluetooth low energy devices in a web browser. It allows web pages to access and control devices via Bluetooth.

[0097] Remote Access

[0098] Remote control principle:

[0099] Since the software is based on the USBIP protocol, the software opens a control port TCP:7575 on the server side, and the client connects to this TCP port to achieve control.

[0100] By analogy, we can open this control port to the Internet through a reverse proxy tool, so that the client can manually enter the proxy server's IP + proxy port for remote control.

[0101] Visitors access the IP and port of the proxy server, and the proxy server helps us access the software service port of the development board, which is equivalent to directly accessing the software control port.

[0102] Network Sharing

[0103] As attached Figure 6 As shown in the figure, the WiFi network connected to the development board can be configured to share the WiFi network with the network card on the development board, so that devices that temporarily need the network can access the Internet.

[0104] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
