Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
It should be understood that the embodiments described are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the embodiments in the present application.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the embodiments of the present application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims. In the description of the present application, it is to be understood that the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not necessarily used to describe a particular order or sequence, nor are they to be construed as indicating or implying relative importance. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated object, indicating that there may be three relationships, for example, a and/or B, which may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The existing industrial equipment generally adopts a TCP direct connection transmission mode, because the data transmission process is streaming transmission, when a plurality of clients transmit data to a server, if an error occurs in the data transmission process of one client, the error occurs in a section of data stream, because the data is streaming transmission, namely the data stream which is continuous according to the execution sequence does not have a certain mark between every two instructions, the specific error process in the execution process cannot be obtained. And the structural data of the sending end needs unpacking, each field needs to be marked in the separation process, and the receiving end splices the data with the discrete received data according to the marking number. In this way, errors and omissions are easily generated in the data separation process due to different data formats.
To solve the problems in the background art, an embodiment of the present application provides a data transmission method applied to a data transmission system, and in a preferred embodiment, the data transmission system includes:
the system comprises a server, a client, a processing center, a system monitor and a service discovery center, wherein the server and the client adopt a distributed issuing mode.
As shown in fig. 1, the method includes:
s01: and the client acquires the proxy information of the server and transmits the local identification code to the server so as to establish connection with the server.
Preferably, the method comprises the following substeps:
s011: and searching a server through the system.
S012: when the server is searched, registering client information and class identification, and transmitting the client information and the class identification to the server during running; the class identification comprises service original data, streaming data obtained after conversion of the original data, framework layer planning data, memory structure data and database mapping data.
The runtime refers to the expression form of data in each workflow, the workflow has a series of nodes (serial, parallel, branched, and merged), and the data has corresponding expression forms according to different nodes.
S02: the server receives an object transmission request sent by the client, searches an object adapted to the client and sends the object to the client; and the object is transmitted according to a preset general data structure corresponding to the object.
For the generic data structure, the following needs to be manually configured:
1) A generic structure (type, attribute, field content) is built that accommodates the network layers.
2) And constructing an Active servant map (lookup table) corresponding to the universal structure, wherein the universal structure is expressed as a server object at the server side and is expressed as a client object at the client side.
3) The server starts and instantiates a server object.
The general structure comprises a plurality of structure types to match different instructions; if the object attribute is modified, the structure is the characteristic ID + the modified object attribute, and the matching is carried out on the general structure in the lookup table according to the characteristic ID; for example, the general structure of the object properties is that the [ time ] interface type interface identifies the interface parameters. The features are separated by separators, and after matching the feature IDs, the features are matched according to the corresponding generic structure, for example: [1] [2022-09-20 00 ]; [1] [ 2022-09-20; and the characteristic IDs of the two groups of data are both 1, and the interface parameters of the interface type identifier of the universal format [ time ] interface are obtained. And performing four times of matching, defining the matching length by different separators, and completing the matching of a group of data. Two instructions are obtained respectively. When the feature IDs are different, the common format is correspondingly changed. And different common formats correspond to different implementation classes. After the data is segmented, the server performs different operations on different data, for example, an object A with a characteristic ID of 1 is used for modifying machine parameter characteristics, after the server receives the object A, the server modifies machine parameters at the server and returns the modified parameters to the client, an object B with a characteristic ID of 2 is used for acquiring machine updating program information, and after the server receives the object B, the server acquires the machine updating program information and packages the information and returns the information to the client. Different instructions are realized through different pipelines, so that the accuracy and the timeliness of data and flow processing are improved.
In a preferred embodiment, the server obtains the generic data structure by:
s1: constructing a service class, and mapping a class structure hierarchy to an operation layer by using a stream processor; the stream processor comprises a data receiving layer, a data compression layer and a data mapping layer;
s2: and performing parameter assignment on the service class according to the service use scene, and constructing a memory structure corresponding to the service use scene.
The parameter assignment of the service class refers to combining related parts into an object or a structural body according to a used scene. The class structure comprises original data, transmission data, compressed data and memory database relational data. The memory structure is a concept in a framework layer, and is characterized by addresses, structure values and transfer data.
Based on the above general data structure, step S02 includes the following substeps:
s021: acquiring a dynamic address of the object by using a detection mechanism; the dynamic address comprises an object ID, an object conversion ID, a memory structure ID and a database structure ID.
S022: and boxing the object into a memory pipeline, and opening an Input structure and an Output structure.
Wherein, the object is boxed into the memory pipeline, which means that the outer layer data, the frame layer data, the conversion layer data and the memory data are stored.
The object required to be transmitted by the client refers to a data execution object, and the data required to be transmitted and processed generates a class structure with different languages and the same construction according to a general structure so as to realize cross-language and platform interaction.
Preferably, after the server searches for the object adapted to the client, the method further includes the following steps:
and the server generates a service object entity requested by the client in a memory snapshot mode.
S03: and the client acquires the use right of the object, wherein the use right comprises the property and the method for modifying the object.

the client maps the object entity to the local end, and when in use, the Input parameter is injected, and the result of the server end is obtained through the method or the attribute in the object layer.
Specifically, the client maps the object entity to the local end, when in use, an Input parameter is injected (an outer layer has a corresponding data expression, application software generates a corresponding UI or logic according to the data expression, and an operator or a logic caller plugs in the data), and a result of the server is obtained through a method or an attribute in the object layer.
S04: and the server receives the object modification request of the client, operates in the visible domain and transmits an operation result to the processing center.
S05: and the processing center distributes the state and the attribute change to the object according to a preset event mechanism.
The data transmission system further includes a monitoring side (system monitor); the method further comprises the steps of:
s06: the monitoring end monitors the life cycles of the client and the server, detects the activity cycle of the object, and generates a heartbeat mechanism according to the life cycle and the activity cycle.
Correspondingly, the client is used for injecting life cycle information (the life cycle of the data stream, which is obtained by the Start node and finally goes to the End node through the common node, the branch node and the comprehensive node) into the monitoring system, so that the monitoring system can determine whether the client is overtime or loses connection.
In a second aspect, the present invention provides a method for implementing service class bussiness function docking, which is applied to a data transmission system, where the data transmission system includes a server, a client, and a processing center, and as shown in fig. 2 and fig. 3, the method includes the following steps:
