Description

Technical Field

[0001] The present application relates to the technical field of virtual single-chip microcomputer systems, and more specifically, to a WiFi-based Web3D virtual single-chip microcomputer digital twin system. Background Art

[0002] Digital twins make full use of data such as physical models, sensor updates, and operation history, integrate multi-disciplinary, multi-physical quantity, multi-scale, and multi-probability simulation processes, and complete mapping in virtual space, thereby reflecting the entire life cycle of the corresponding physical equipment. Digital twins are a concept that transcends reality and can be regarded as a digital mapping system of one or more important, interdependent equipment systems. Digital twins are a universally applicable theoretical and technical system, and are now widely used in product design, product manufacturing, medical analysis, engineering construction, and other fields.

[0003] At present, using WiFi communication to connect to the Internet is a widespread application; and for single-chip microcomputer systems, there are many application scenarios for using WiFi to communicate and remotely control single-chip microcomputer systems, so the development of single-chip microcomputer systems based on WiFi communication technology has become a hot research topic. In the development of single-chip microcomputer systems, since direct development using real single-chip microcomputer hardware will result in excessive costs, virtual single-chip microcomputer system development technology has emerged in the prior art. In the invention patent with application number 2022100240762 and the theme of "Web3D virtual single-chip microcomputer digital twin system based on ZigBee", it is proposed to use ZigBee communication technology to map virtual and real single-chip microcomputers to each other to improve the efficiency of system development; however, ZigBee communication technology is a short-range, low-energy technology. Compared with WiFi communication, there are significant differences in the way the two are connected to devices. When using WiFi communication to develop a single virtual single-chip microcomputer system mapping multiple real single-chip microcomputer systems or multiple virtual single-chip microcomputer systems mapping multiple real single-chip microcomputer systems, the above-mentioned development technology is used. If the technical solution of the patent is not disclosed, it may cause confusion in the mapping of virtual and real single-chip microcomputer systems, and the virtual and real systems cannot be precisely paired with each other, resulting in confusion in the development of system functions; although in the application number 202111252171.X, the theme is "A Collaborative Operation System of Web3D Multi-Virtual Single-chip Microcomputer Systems", the technology of using digital encoding and decoding is disclosed, combined with a computing encoder and an analytical decoder, so that the mutually mapped virtual and real single-chip microcomputer systems can achieve precise pairing. However, in the development of real single-chip microcomputer systems using WiFi communication, it is usually necessary to configure a gateway for communication channel regulation, and the use of encoding and decoding technology will undoubtedly bring a lot of additional development costs to the development, so this technology is not completely suitable for the development of single-chip microcomputer systems in this scenario, and it is difficult to support the verification of single-chip microcomputer functions. It can be said that the use of digital twin technology to perform virtual-to-real mapping operations on single-chip microcomputer systems that communicate based on WiFi is still blank.

[0004] Therefore, how to provide a WiFi-based Web3D virtual MCU digital twin system, which can accurately map the virtual and real MCU systems based on control codes when using WiFi networking, thereby improving system development efficiency and greatly saving development costs, has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0066] Specifically, in an embodiment of the present invention, the WiFi-based Web3D virtual single-chip microcomputer digital twin system also includes: a control terminal 13 arranged between the MQTT server 7 and the virtual single-chip microcomputer system 2.

[0067] Specifically, in an embodiment of the present invention, the control terminal 13 includes: a first IP acquisition module 1301; the first IP acquisition module 1301 is connected to the IP receiving module 301 and the MQTT server 7 to obtain the default IP address from the MQTT server 7; a data synchronization module 1302, the data synchronization module 1302 is used to synchronize the operating status information and IP address information of the virtual single-chip microcomputer system 2 and the real single-chip microcomputer system 5; and an instruction configuration module 1303 connected to the IP acquisition module and the data synchronization module 1302; the instruction configuration module 1303 is used to set system pairing instructions and data synchronization instructions; the system pairing instructions carry the first IP address information.

For this conflict, the ARP table entry is first obtained through the third IP acquisition module 306, and the first IP address information is extracted therefrom, and the risk of the second IP conflict is avoided in combination with the second IP comparison module 304.

After compilation and running, the code is burned into the real single-chip microcomputer system 5 through the real burner 12, and the second IP address is set through the real upper level, and then connected to the WiFi network in combination with the communication gateway 8.

[0076] Specifically, in an embodiment of the present invention, data is uploaded to the MQTT server 7 in real time via the MQTT protocol.

[0077] Among them, in the 3D virtual scene 1, the virtual single-chip computer system 2 and the real single-chip computer system 5 are mapped one by one according to the IP address.
