and returning the target protocol analysis component to the industrial gateway through an IP network.
After receiving a protocol analysis request, the industrial field protocol configuration platform calls a pre-stored protocol analysis component library so as to determine the protocol type which can be analyzed by each target protocol analysis component, then judges whether the data to be analyzed is matched with the protocol type, if so, judges whether the data to be analyzed is matched according to the protocol message field in the data to be analyzed, and if so, can determine the target protocol analysis component required by analyzing the data to be analyzed so as to provide the required target protocol analysis component for the industrial gateway in time.
In one embodiment, the method further comprises:

1) Protocol analysis request receiving module
And the system is responsible for receiving a protocol analysis request from the industrial gateway, wherein the request is attached with protocol message field information of an industrial field protocol.
(different protocols have different specific field differences, and are larger, some protocols are binary, for example, an IP message of an Ethernet protocol interface has a 12-byte MAC address and a 0x800 field is arranged behind the MAC address to identify the IP message, because various protocols on an industrial field have more types, the IP message can be conveniently identified as long as the protocol message format is open, of course, the identification field of each protocol is also different, and the invention is not limited)
2) Protocol identification module
The system is responsible for identifying the protocol type according to the field information of the protocol message of the industrial field protocol, if the protocol characteristics are obvious, the protocol type can be automatically identified through a program, if the protocol characteristics cannot be automatically identified, a user is prompted to identify the protocol type through a manual mode, and finally the protocol type is manually input through a configuration page of the platform. Different protocols and different protocol characteristics are different, and generally disclosed protocols have own encapsulation formats, such as an IP message, namely a destination MAC (media access control), a source MAC (media access control) and then the IP message.
3) Protocol analysis component library
A collection of protocol resolution components for various industrial sites.
4) Protocol analysis component pushing module
And pushing the corresponding protocol analysis functional component to the industrial gateway through the IP network, and calling a functional interface provided by the component after the gateway loads the component.
The invention also defines an industrial gateway, which, as shown in fig. 3, comprises the following three modules:
1) Protocol analysis request sending module
The gateway is responsible for sending a protocol analysis component loading request to the configuration platform, and because the gateway is not responsible for identifying the protocol type, the corresponding protocol message field needs to be packaged into a request message and sent to the configuration platform, and the configuration platform completes the protocol identification process.
2) Protocol analysis component loading module
And receiving a protocol analysis component from the configuration platform and loading the protocol analysis component to an executable environment of the industrial gateway.
3) Protocol analysis component execution module

The function of analyzing the operation parameters of the equipment is to monitor the state of the equipment, and the equipment can be digitally modeled, which is also the basis of the frequently mentioned digital twins. The operation parameters include various information of the equipment, and the operation parameters of the equipment can be angles, coordinate positions and the like of the mechanical arm.
An example of the operation of the present invention is shown in FIG. 4 below:
the method comprises the following specific steps:
the industrial gateway accesses a new industrial device and receives an unrecognized protocol type.
The gateway sends the unrecognizable protocol message field to the configuration platform through an IP link, and the request platform analyzes the specific protocol type.
After receiving the request message, the configuration platform identifies the protocol type according to the field of the protocol message, if the protocol characteristic is obvious, the protocol type can be automatically identified through a program, if the protocol characteristic cannot be automatically identified, the configuration platform prompts a user to identify the protocol type through a manual mode, and finally, the protocol type is manually input through a configuration page of the platform. The protocol type is identified in this example as protocol a.
The configuration platform pushes the parsing component of protocol a to the industrial gateway over the IP link.
And after receiving the analysis component of the protocol A, the industrial gateway loads the analysis component into the operating environment of the industrial gateway and starts the analysis process of the protocol A.

7. The utility model provides a system for industry field protocol automatic analysis based on high in clouds discernment which characterized in that, the system includes industry gateway and industry field protocol configuration platform, wherein, industry gateway includes:
the receiving module is used for receiving a protocol analysis request sent by an industrial field;
the request sending module is used for sending a component request message to a preset industrial field protocol configuration platform according to the protocol analysis request;
the protocol analysis component receiving module is used for receiving a target protocol analysis component returned by the industrial field protocol configuration platform based on the component request message;
the protocol analysis component execution module is used for analyzing the data to be analyzed corresponding to the protocol analysis request received by the industrial gateway based on the target protocol analysis component to obtain corresponding equipment operation parameters;
the protocol analysis group execution module is further configured to send the device operating parameters and the to-be-analyzed data to an assembly management and control platform, so that the assembly management and control platform analyzes analysis performance indexes of the device operating parameters, where the analysis performance indexes include at least one of the following: the analysis accuracy, the analysis delay and the analysis duration are controlled;
judging the superiority and inferiority of the target protocol analysis component according to the analysis performance index;
determining whether performance optimization needs to be carried out on the target protocol analysis component or not according to the advantages and disadvantages of the target protocol analysis component;
and when the performance of the target protocol analysis assembly needs to be optimized, the target protocol analysis assembly is sent to the assembly management and control platform for upgrading.
8. The system of claim 7, wherein the industrial field protocol configuration platform comprises:
the judging module is used for judging whether a protocol message field can be identified from the protocol analysis request or not after the protocol analysis request is received;
the identification module is used for identifying the protocol type corresponding to the protocol analysis request according to the protocol message field when the protocol message field can be identified;
and the sending module is used for sending the identified corresponding protocol to the industrial gateway.
9. The system of claim 8, wherein the industrial field protocol configuration platform is further configured to:
when the protocol message field cannot be identified from the protocol analysis request, generating a protocol type prompt notice;
sending the protocol type prompt notification to a target terminal to request a user of the target terminal to identify the protocol type corresponding to the data to be analyzed;
and after receiving a protocol type identification result sent by the target terminal, sending the protocol type identification result to the industrial gateway.
