[0022] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0023] See also Figure 1 As shown, a serial port device remote maintenance system of the present invention includes: a serial port client 1, an integrated management platform 2, a VPN virtual network service module 3 and an industrial intelligent gateway 4. The serial port client 1 interacts with the integrated management platform 2, connects to the VPN virtual network service module 3, and communicates with the industrial intelligent gateway 4; the industrial intelligent gateway 4 connects to the serial port device, and connects to the serial port client 1 through the VPN virtual network service module 3 to achieve remote monitoring and maintenance.

[0024] The serial port client 1 realizes data conversion and communication with the operation and maintenance software 5. The serial port client 1 is installed on the user's computer. First, log in with the user password on the serial port client 1, obtain the industrial intelligent gateway 4 authorized by the integrated management platform 2, and operate to connect to the industrial intelligent gateway 4. Figure 2 At the same time, the serial port client 1 dynamically creates a virtual serial port, and the built-in first data conversion module CTC parses the TCP data stream from the VPN virtual network service module 3 and writes it to the virtual serial port. In this way, the user's operation and maintenance software 5 (the user's original equipment maintenance software, such as PLC software, etc.) only needs to access the local virtual serial port to achieve real-time monitoring and maintenance operations on the remote field serial port device 6.

[0025] For details, see Figure 3 As shown, the serial port client 1 first logs in to the integrated management platform 2 through an HTTP request, and after establishing a communication channel with the VPN virtual network service module 3, a virtual serial port pair A and B are dynamically created. The virtual serial port A is connected to the first data conversion module CTC, and real-time communication is achieved between the virtual serial port A and the virtual serial port B. The first data conversion module CTC is responsible for parsing the TCP data stream from the VPN virtual network service module 3 and writing it to the virtual serial port A, while converting the data interacted with the virtual serial port B into a TCP data stream and sending it to the VPN virtual network service module 3. The user's operation and maintenance software 5 realizes real-time monitoring and maintenance operations on the remote field serial port device 6 by accessing the virtual serial port B.

[0026] The integrated management platform 2 is responsible for managing the users of the serial port client 1 and the industrial intelligent gateway 4. The integrated management platform 2 is installed on the server, and it establishes the files of the serial port client 1 user and the industrial intelligent gateway 4 respectively, and authorizes the corresponding industrial intelligent gateway 4 access rights for the client user. The integrated management platform 2 is also responsible for establishing the basic communication link of the industrial intelligent gateway 4 and the communication with the VPN virtual network service module 3. Among them, the basic communication link is used to maintain the communication between the industrial intelligent gateway 4 and the integrated management platform 2, and the VPN link is used for data transmission of the serial port device 6 on site.

[0027] For details, see Figure 4 As shown, the integrated management platform 2 includes a basic archive module, an authorization and authentication module, a channel management module and a communication module. The basic archive module is responsible for managing the users of the serial port client 1 and the industrial intelligent gateway 4. The authorization and authentication module is used to authenticate the user login of the serial port client 1 and authorize it to access the industrial intelligent gateway 4 (such as user A authorizes gateway B, A can access gateway B). The communication module is used to manage and maintain the communication link of the industrial intelligent gateway 4, such as the industrial intelligent gateway 4 establishes a connection with the integrated management platform 2 through the MQTT protocol and maintains link communication. The channel management module is used to establish communication between the user of the serial port client 1 and the industrial intelligent gateway 4 and the VPN virtual network service module 3. The serial port client 1 and the industrial intelligent gateway 4 exist in the VPN virtual network service module 3 in the form of nodes, and network-level communication is realized through virtual network services.

[0028] The VPN virtual network service module 3 maintains a virtual channel between the serial port client 1 and the industrial intelligent gateway 4. It provides a secure and stable virtual channel for the serial port client 1 and the industrial intelligent gateway 4. The serial port client 1 and the industrial intelligent gateway 4 exist in the virtual network service in the form of nodes, and network-level communication is achieved through the virtual network service.

[0029] The industrial intelligent gateway 4 realizes communication and data transmission with the on-site serial port device 6. It connects to the on-site serial port device 6, establishes a two-way channel with the integrated management platform 2, and encapsulates the original data of the on-site serial port device 6 into a TCP data packet through the application conversion module. Communication with the on-site serial port device 6 is realized through a virtual network, thereby realizing remote transmission of data. That is, the on-site serial port device 6 is connected to the physical serial port of the industrial intelligent gateway 4, the industrial intelligent gateway 4 communicates with the VPN virtual network service module 3, and the remote serial port client 1 communicates with the VPN virtual network service module 3, so as to realize communication between the on-site serial port device 6 and the remote serial port client 1.

[0030] For details, see Figure 5As shown, the industrial intelligent gateway 4 first establishes a communication connection with the integrated management platform 2 through the MQTT protocol, and establishes a communication channel with the VPN virtual network service module 3. The industrial intelligent gateway 4 and the integrated management platform 2 first establish a communication link, and the opening and closing of the virtual network of the VPN virtual network service module 3 are issued through the MQTT link. The second data conversion TTC module is responsible for encapsulating the original data of the on-site serial port device 6 into TCP data packets and forwarding them to the VPN virtual network service module 3, while receiving TCP data packets from the VPN virtual network service module 3 and parsing and converting them into serial port data and passing them to the on-site serial port device 6.

[0031] In summary, the serial port device remote maintenance system of the present invention realizes the remote maintenance of the on-site serial port device 6, relying on the close cooperation and mutual coordination between the serial port client 1, the integrated management platform 2, the VPN virtual network service module 3 and the industrial intelligent gateway 4, forming an efficient working system. Through this system, users can easily transcend geographical restrictions and realize remote monitoring and maintenance operations of the on-site serial port device 6. Not only does it improve work efficiency, but it also reduces maintenance costs and time consumption. It makes the remote monitoring and maintenance operations of the on-site serial port device 6 more convenient and efficient, bringing new possibilities for industrial production and equipment management.
