Description

Technical Field

[0001] This utility model relates to the field of operating terminal technology, and more specifically, to a digital twin-driven visual remote operating terminal. Background Technology

[0002] In the field of operator terminal technology, with the deepening of industrial automation and intelligence, remote operator terminals are playing an increasingly important role in the control of industrial equipment such as CNC machine tools. In particular, the deep integration of digital twin technology and visual interaction has placed higher demands on remote operator terminals.

[0003] Chinese patent application No. 202411461688.3 discloses an "Intelligent Remote Machine Tool Operation Platform Based on Digital Twin." While this platform involves the application of digital twins in remote machine tool operation, capable of collecting machine tool operating data, identifying startup parameters, and analyzing performance stability, thus improving the accuracy and efficiency of machine tool operation to some extent, it suffers from significant shortcomings in hardware integration and software interaction optimization. Its hardware does not employ an integrated design; the functional modules are scattered, resulting in a large overall device size, poor portability, and inconvenience for operators in mobile scenarios. Regarding software interaction, the platform lacks a 3D visualization interface for the digital twin, failing to provide operators with an intuitive virtual model of the machine tool. Furthermore, it does not support convenient interactive operations such as gesture zooming and rotation, making it difficult for operators to comprehensively and efficiently control the remote operation status of the machine tool.

[0004] Furthermore, existing remote operation platforms of this type have shortcomings in terms of operator posture perception and on-site environmental parameter acquisition. Most are not equipped with high-precision gyroscopes to accurately perceive operator posture, making it difficult to match the operator's operating habits and affecting the smoothness of operation. At the same time, in terms of on-site environmental parameter acquisition, they can often only obtain limited parameter information and cannot comprehensively and in real time reflect the environmental conditions of the machine tool working site. In CNC machine tool processing scenarios where the environment is more sensitive, this may adversely affect the safety and reliability of remote operation. Utility Model Content

[0042] Furthermore, the edge computing module 11 uses a multi-core processor with a main frequency of no less than 2.0GHz. It is attached to the metal heat sink 15 on the inner side of the back of the portable body 1 by thermal silicone. The metal heat sink 15 is integrally formed with the shell of the portable body 1.

[0043] The multi-core processor used in the edge computing module 11 ensures data processing capabilities. Thermal silicone combined with the metal heat sink 15 on the inner side of the back of the portable chassis 1 forms an efficient heat dissipation system. The unibody metal heat sink 15 enhances heat dissipation and the structural strength of the portable chassis 1. The multi-core processor meets the edge computing module 11's need for rapid processing of large amounts of data; the efficient heat dissipation system prevents the edge computing module 11 from overheating and affecting its performance, extending its lifespan; the unibody design of the metal heat sink 15 improves the robustness of the portable chassis 1 and enhances the device's durability.

The built-in antenna 16, arranged in an L-shape inside the top corner of the portable device 1, expands the signal reception range and optimizes the transmission and reception path of the 5G communication signal. This enhances the stability and transmission rate of the communication signal between the 5G communication module 12 and the built-in antenna 16, ensuring real-time remote data interaction, reducing signal latency, and improving the timeliness and reliability of remote operation.

[0046] Furthermore, the input button 3 includes at least 5 custom function buttons arranged linearly on the bottom of the portable body 1, with the button protrusion height not exceeding 1.5mm, and connected to the edge computing module 11 via a thin-film circuit.

[0047] At least five customizable function keys on input button 3 are linearly arranged on the bottom of the portable device 1 for easy operation.

[0048] When the digital twin-driven visual remote operation terminal of this utility model is in use, after the terminal is started, the lightweight digital twin engine built into the edge computing module 11 begins to run. The 5G communication module 12 automatically searches for and connects to the communication network of the remote device through the built-in antenna 16 connected by the radio frequency coaxial cable, establishing a stable data transmission link. At the same time, the onboard circuit 4 completes the electrical connection between the edge computing module 11 and components such as the display screen 2, input buttons 3, high-precision gyroscope 13, and environmental sensor 14, and each module enters a standby state.

[0049] The detection end of the environmental sensor 14 is exposed on the side wall of the portable device 1, collecting environmental parameters such as temperature, humidity, and air pressure in real time, and transmitting the data to the edge computing module 11 via the onboard circuit 4. The high-precision gyroscope 13, installed at a 45° angle to the central axis of the portable device 1, accurately captures the operator's posture changes while holding the terminal, sending the posture signal to the edge computing module 11 in real time.
