(1) When the 5G intelligent control device 102 shown in the figure is powered on, 5G network signals in the area range are automatically searched, and after the 5G wireless access and transmission network 2 with the strongest signal in the range is searched, a random access application is sent to the 5G wireless access and transmission network 2.

(2) After the 5G wireless access and transmission network 2 automatically monitors the access application of the 5G intelligent control device 102, it agrees to the access of the 5G intelligent control device 102, and requires the 5G intelligent control device 102 to complete the second step of link registration within a specified time delay, and when the link is completed, it needs to provide information such as device type, and waits for the second step of link request of the 5G intelligent control device 102.

(3) After receiving the second link request, the 5G intelligent control device 102 prepares the relevant data and initiates a second link registration request.

(4) After automatically monitoring the second-step link request and the attached related device data of the 5G intelligent control device 102, the 5G wireless access and transmission network 2 sends the related device data to the wireless resource and link management module 301, and the wireless resource and link management module 301 automatically determines the network transmission configuration parameter range of the 5G intelligent control device 102 according to the device information and the parameters such as the previous two-step access and transmission delay, and sends the parameters to the data processing and storage module 302 for confirmation. And the 5G intelligent control device 102 is required to complete the third step of link registration within a specified time delay, and parameter information such as the size of device register data needs to be provided during link, and a third step of link request of the 5G intelligent control device 102 is waited.

(5) After receiving the third link request, the 5G intelligent control device 102 prepares related data and initiates a third link request for registration.

(6) After automatically monitoring the third-step link request of the 5G intelligent control device 102 and the attached related device data, the 5G wireless access and transmission network 2 sends the related device data to the data processing and storage module 303, the data processing and storage module 303 compares the received receipt with the data sent by the wireless resource and link management module 301 after calculation, takes the optimal parameters of the two as the configuration parameters of the final 5G intelligent control device 102, generates a unique core authentication code and related configuration parameters of the whole plant, and sends the core authentication code and related configuration parameters as the identity authentication and parameter configuration file of the 5G intelligent control device 102 to the 5G intelligent control device 102.

(7) After receiving the "core authentication code" and the relevant configuration parameters, the 5G intelligent control device 102 immediately updates the configuration of the device, and links with the 5G wireless access and transmission network 2 according to the configuration to prepare for the next transmission.

After the 5G intelligent instrument and the intelligent control equipment in the controlled range are accessed and authenticated according to the flow and the link with the control system is successfully established, the management and control system can virtualize the whole operation capacity and storage capacity by means of strong data logic operation capacity, data storage capacity and operation virtualization of the edge computing center control module, and the initialization and real-time data processing of the management and control system are realized according to the parameters of the on-site 5G intelligent instrument and the intelligent control equipment, so that the production process is monitored. By taking the function of the edge computing center control module in fig. 3 and the real-time data structure diagram of the management and control system in fig. 4 as an example, how the management and control system of the present invention utilizes the real-time data of the 5G intelligent device to realize the monitoring of the process parameters, the analysis of the control logic, and the issuing of the control logic, thereby realizing the monitoring of the production process and the storage of the real-time data.

1) As mentioned above, after the connection is established between the in-situ intelligent instrument and the intelligent control device and the edge computing center module 30 of the management and control system, the management and control system establishes the unique core authentication code of the device to be identified in the management and control system; the edge center control module can read the equipment operation and management data stored in the internal memories such as the data acquisition area, the control data area, the management data area and the like from the intelligent equipment register in real time according to the unique core authentication code of the equipment.

4) Because the device management data does not participate in the production process control, the data processing and storing module 303 of the management data area establishes a non-logical database using the unique core authentication code of the device as an index, and directly stores the data of the management data area into the non-logical database. Similarly, the non-logical databases are virtual parts dynamically allocated in the edge center data processing and storing module 303 according to the production process and the operation requirement, and after the data storage of the non-logical databases is virtualized, the large-scale computing center and the large-scale database are respectively configured according to the data function, so that the separation of the equipment management data and the control data is realized.
