Description

Technical Field

[0002] With the rapid development of various IT technologies such as 5G, IoT, big data, and AI in recent years, the research and development direction of construction machinery equipment (such as lifting equipment, pumping equipment, and excavating equipment) has shifted towards intelligent development. Beyond traditional, simple industrial control data, the addition of new technologies, including but not limited to digital twins built based on a large number of sensors, remote control based on high-bandwidth, low-latency 5G networks with rich video surveillance and PLC data, and remote monitoring using autonomous driving technology, will provide the next generation of construction machinery equipment with superior operating efficiency and safer operating modes.

[0003] The inventors discovered the following problems with existing network communication methods for remotely controlling engineering machinery: Figure 1 As shown, existing technologies require a dedicated, single backend relay module to exchange all data between the host and control sides in real time, enabling the control side to issue commands and collect data from the host side.

In other words, the aforementioned network communication method suffers from the need for one-to-one configuration between the control and host sides, resulting in inconvenient management, and the inability for the control and host sides to communicate with each other, leading to low data transmission privacy.

[0052] See Figure 2 This application provides a network communication system applicable to the remote control of engineering machinery. The system includes a host-side device, a control-side device, and a back-end device. The host-side device includes an edge computing module and a first network communication module. The control-side device includes a real-time control module and a second network communication module. The back-end device includes a signaling management module and an access gateway module.

[0053] The signaling management module is used to acquire pairing requirements, which include host-side devices and control-side devices that need to interface with each other; determine a target access gateway based on the location information corresponding to the host-side devices and the control-side devices respectively; the target access gateway is the gateway required for the host-side devices and control-side devices to achieve network interconnection; perform network interconnection configuration operations based on preset information corresponding to the host-side devices and control-side devices respectively, determine the first network connection configuration information corresponding to the host-side devices, the second network connection configuration information corresponding to the control-side devices, and the third network connection configuration information corresponding to the target access gateway; and send the first network connection configuration information to the host-side devices, the second network connection configuration information to the control-side devices, and the third network connection configuration information to the access gateway module.

[0054] The access gateway module is used to load the third network connection configuration information;

[0055] The edge computing module is configured to, after executing the first network connection configuration information, control the first network communication module to load the first network connection configuration information and connect to the access gateway module to access the target access gateway;

[0056] The real-time control module is used to control the second network communication module to load the second network connection configuration information and connect to the access gateway module after executing the second network connection configuration information, so as to access the target access gateway.

[0057] Optionally, after the registered host-side devices and control-side devices in the signaling management module of the backend device go online, the signaling management module can be aware of the online host-side devices and control-side devices. When the user needs to configure host-side devices and control-side devices to interface with each other, the signaling management module can obtain the corresponding pairing requirements. The pairing requirements include the host-side devices and control-side devices that need to interface with each other. Specifically, the pairing requirements may include information such as the identity identifiers of the host-side devices and control-side devices that need to interface with each other.

[0058] Optionally, since the host-side device and the control-side device may be located in the same city, different cities, or even different countries, it is necessary to first determine the gateway required for the host-side device and the control-side device to achieve network interconnection, i.e., the target access gateway, based on the network information corresponding to the host-side device and the control-side device respectively. The network information includes, but is not limited to, Internet Protocol addresses (IP addresses). Here, the gateway may specifically be a network server, etc.

[0059] The preset information can be used to characterize the network environment and identity of the device. Optionally, the preset information includes local area network information, internet information, and identity information. Internet information may include IP addresses, etc., and identity information, used to distinguish different devices, may include serial numbers, etc.

[0060] Optionally, since the host-side device and the control-side device may be located in different local area networks (LANs) and access different internet networks, basic interconnection can be achieved based on internet information, and LAN information can be exchanged to achieve interoperability between LANs. That is, the first network connection configuration information may include the LAN information, internet information, and identity information corresponding to the control-side device; the second network connection configuration information may include the LAN information, internet information, and identity information corresponding to the host-side device; and the third network connection configuration information may include the LAN information, internet information, and identity information corresponding to both the host-side device and the control-side device.

[0061] Optionally, the signaling management module sends the first network connection configuration information to the host-side device, so that after the edge computing module of the host-side device executes the first network connection configuration information, it controls the first network communication module to load the first network connection configuration information and connect to the access gateway module to access the target access gateway. Simultaneously, the signaling management module sends the second network connection configuration information to the control-side device, so that after the real-time control module of the control-side device executes the second network connection configuration information, it controls the second network communication module to load the second network connection configuration information and connect to the access gateway module to access the target access gateway. Furthermore, the signaling management module sends the third network connection configuration information to the access gateway module, and the access gateway module loads the third network connection configuration information to verify the host-side device and control-side device accessing the target access gateway, thereby enabling network interoperability between the host-side device and the remote control-side device.

[0062] It should be noted that the access gateway module can provide the target access gateway or an access point to the target access gateway. By loading the third network connection configuration information, the host-side device and the control-side device can be connected to the target access gateway. It is understood that since users can randomly pair the host-side device and the control-side device according to control requirements through the signaling management module, one-to-one configuration between the control side and the host side is unnecessary. Furthermore, network interconnection between the host-side device and the control-side device is achieved through the access gateway module, eliminating the need for data interaction through third-party services and improving data transmission privacy.

[0063] In summary, in the system provided by the above embodiments, after obtaining the pairing requirement, the target access gateway is determined based on the network information corresponding to the host-side device and the control-side device, respectively. Then, a network interconnection configuration operation is performed based on the preset information corresponding to the host-side device and the control-side device, respectively, to determine the first network connection configuration information corresponding to the host-side device, the second network connection configuration information corresponding to the control-side device, and the third network connection configuration information corresponding to the target access gateway. This enables the host-side device and the control-side device to access the target access gateway according to the corresponding network connection configuration information, thereby achieving network interconnection. This allows for automatic configuration of the host-side device and the control-side device based on requirements, eliminating the need for one-to-one configuration between the control side and the host side. It facilitates the management of the host-side device and the remote control side device, enables rapid interconnection, and ensures high data transmission privacy.

[0064] Optionally, the signaling management module obtains the pairing requirements, including:

[0065] In response to a pairing request command, a pairing interface is output; the pairing interface includes information on at least one candidate host-side device and at least one candidate control-side device after going online.

[0066] The selection command entered through the pairing interface is obtained, and the corresponding pairing requirements are generated.

[0067] Optionally, after receiving a pairing request instruction, the signaling management module of the backend device can output a pairing interface including information on at least one candidate host-side device and at least one candidate control-side device after going online. This allows the user to select the host-side and control-side devices that need to be interconnected. Upon receiving the selection instruction input through the pairing interface, the module generates a corresponding pairing requirement based on the selection instruction. It should be noted that the pairing interface output by the signaling management module of the backend device can be displayed via a webpage or other means on a display device. This allows for selection of host-side and control-side devices that need to be interconnected based on requirements, providing flexible operation and enabling simultaneous management of multiple devices, thus improving the user experience.

[0068] Optionally, continue reading Figure 2 The host-side device further includes a video management module, and the control-side device further includes a real-time video monitoring module; wherein,

[0069] The real-time video monitoring module is used to send monitoring instructions to the video management module through the second network communication module and the access gateway module; and to obtain monitoring data corresponding to the monitoring instructions and display the monitoring screen corresponding to the monitoring data.

[0070] The video management module is used to send the monitoring data collected by the corresponding camera device installed on the host side device to the real-time video monitoring module through the first network communication module and the access gateway module, according to the monitoring instruction.

[0071] Specifically, when the control-side device needs to monitor the host-side device, the real-time video monitoring module can send a monitoring command to the video management module of the host-side device through the second network communication module and the access gateway module to request monitoring data of the host-side device. After receiving the monitoring command, the video management module can send the monitoring data collected by the corresponding camera device installed on the host-side device to the real-time video monitoring module through the first network communication module and the access gateway module. The real-time video monitoring module receives the monitoring data corresponding to the monitoring command and displays the monitoring screen corresponding to the monitoring data for user viewing. In this way, the host-side device can be monitored without relying on third-party cloud video services, and the video data transmission has a high degree of privacy.

[0072] Optionally, continue reading Figure 2 The control-side device further includes a real-time data acquisition module, and the back-end device further includes a conventional data acquisition module; wherein,

[0073] The real-time control module is also used to send control commands to the host-side device through the second network communication module and the access gateway module;

[0074] The edge computing module is also used to control the host-side device to perform corresponding operations according to the control instructions;

[0075] The conventional data acquisition module is also used to collect the operation data of the host-side device performing corresponding operations, and send the operation data to the real-time data acquisition module through the access gateway module.

[0076] Specifically, when the control-side device needs to control the host-side device, the real-time control module can send control commands to the host-side device through the second network communication module and the access gateway module, such as control commands to control the host-side device to perform preset operations. After receiving the control commands through the first network communication module, the edge computing module controls the host-side device to perform corresponding operations according to the control commands. The conventional data acquisition module of the back-end device can collect the operation data of the host-side device performing the corresponding operations and send the operation data to the real-time data acquisition module through the access gateway module, so that the control-side device can understand the execution status of the host-side device in a timely manner. In this way, timely processing and feedback of remote control operations can be achieved, reducing network latency.

[0077] Optionally, the first network communication module and the second network communication module support communication and forwarding of NAT, IPsec VPN, and related network protocols. Thus, by supporting multiple network communication mechanisms, a network communication model capable of supporting both unidirectional and bidirectional communication is established, improving the compatibility of the underlying network.

[0078] See Figure 3 This application provides a network communication method, which can be executed by a network communication device provided in this application. The network communication device can be implemented in software and / or hardware. In this embodiment, the execution subject of the network communication method is a backend device in a network communication system, such as a cloud server. The network communication method provided in this embodiment includes:

[0079] Step S1: Obtain pairing requirements, which include host-side devices and control-side devices that need to be connected to each other.

[0080] Optionally, after the registered host-side devices and control-side devices in the backend-side devices go online, the backend-side devices can be aware of the online host-side devices and control-side devices. When users need to configure host-side devices and control-side devices to interface with each other, the backend-side devices can obtain the corresponding pairing requirements. The pairing requirements include the host-side devices and control-side devices that need to interface with each other. Specifically, the pairing requirements may include information such as the identity identifiers of the host-side devices and control-side devices that need to interface with each other.

[0081] Optionally, obtaining the pairing requirement includes:

[0082] In response to a pairing request command, a pairing interface is output; the pairing interface includes information on at least one candidate host-side device and at least one candidate control-side device after going online.

[0083] The selection command entered through the pairing interface is obtained, and the corresponding pairing requirements are generated.

[0084] Optionally, after receiving a pairing request instruction, the backend device can output a pairing interface including information on at least one candidate host-side device and at least one candidate control-side device after going online. This allows the user to select the host-side and control-side devices to be paired. Upon receiving the selection instruction input through the pairing interface, the device generates a corresponding pairing requirement based on the selection instruction. It should be noted that the backend device can output the pairing interface via a display device, such as a webpage. This allows for flexible selection of host-side and control-side devices based on requirements, enabling simultaneous management of multiple devices and improving the user experience.

[0085] Step S2: Determine the target access gateway based on the network information corresponding to the host-side device and the control-side device respectively; the target access gateway is the gateway required for the host-side device and the control-side device to achieve network interconnection.

[0086] Optionally, since the host-side device and the control-side device may be located in the same city, different cities, or even different countries, it is necessary to first determine the gateway required for the host-side device and the control-side device to achieve network interconnection, i.e., the target access gateway, based on the network information corresponding to the host-side device and the control-side device respectively. The network information includes, but is not limited to, Internet Protocol addresses (IP addresses). Here, the gateway may specifically be a network server, etc.

[0087] Step S3: Perform network interconnection configuration operation according to the preset information corresponding to the host-side device and the control-side device respectively, and determine the first network connection configuration information corresponding to the host-side device, the second network connection configuration information corresponding to the control-side device and the third network connection configuration information corresponding to the target access gateway.

[0088] The preset information can be used to characterize the network environment and identity of the device. Optionally, the preset information includes local area network information, internet information, and identity information. Internet information may include IP addresses, etc., and identity information, used to distinguish different devices, may include serial numbers, etc.

[0089] Optionally, since the host-side device and the control-side device may be located in different local area networks (LANs) and access different internet networks, basic interconnection can be achieved based on internet information, and LAN information can be exchanged to achieve interoperability between LANs. That is, the first network connection configuration information may include the LAN information, internet information, and identity information corresponding to the control-side device; the second network connection configuration information may include the LAN information, internet information, and identity information corresponding to the host-side device; and the third network connection configuration information may include the LAN information, internet information, and identity information corresponding to both the host-side device and the control-side device.

[0090] Step S4: Send the first network connection configuration information to the host-side device, send the second network connection configuration information to the control-side device, and load the third network connection configuration information so that the host-side device and the remote control-side device can access the target access gateway to achieve network interconnection.

[0091] Optionally, the backend device sends the first network connection configuration information to the host device, so that the host device loads the first network connection configuration information and accesses the target access gateway. It also sends the second network connection configuration information to the control device, so that the control device loads the second network connection configuration information and accesses the target access gateway. The backend device also loads the third network connection configuration information to verify the host device and control device accessing the target access gateway, thereby enabling the host device and the remote control device to access the target access gateway and achieve network interconnection.

[0092] In summary, the method provided in the above embodiments, after obtaining the pairing requirement, determines the target access gateway based on the network information corresponding to the host-side device and the control-side device, respectively. Then, it performs a network interconnection configuration operation based on the preset information corresponding to the host-side device and the control-side device, respectively, to determine the first network connection configuration information corresponding to the host-side device, the second network connection configuration information corresponding to the control-side device, and the third network connection configuration information corresponding to the target access gateway. This enables the host-side device and the control-side device to access the target access gateway according to the corresponding network connection configuration information, thereby achieving network interconnection. This allows for automatic configuration of the host-side device and the control-side device based on requirements, eliminating the need for one-to-one configuration between the control side and the host side.
