Detailed Description
The present invention is further described with reference to the accompanying drawings, and the following examples are only for clearly illustrating the technical solutions of the present invention, and should not be taken as limiting the scope of the present invention.
Example 1
As shown in fig. 1, an RPA flow representation method provided in an embodiment of the present invention includes the following steps:
s1, acquiring an RPA flow, wherein the RPA flow represents a task which can be executed by an RPA robot and is generally executed by a plurality of steps, and each step is a basic operation, such as clicking a button and opening a file. The representation method of the RPA flow has various methods, and can be used for designing documents for the RPA requirement and also can be used for executing the code and pseudo code representation; for example, an RPA flow is represented in the form of a requirement document: the user wants to perform a plurality of search operations and save the search results in one file.
The operation steps in the RPA process are converted into nodes one by one, and the nodes are also called RPA components. Taking the above example flow as an example, a plurality of search operations are first converted into a "For loop" node, and are implemented by repeatedly executing a plurality of search sub-flows. After the multiple searches are completed, the user is notified of the completion of the execution using a message box, which is the main flow. Each search sub-process includes a number of steps: opening a webpage, finding a search button, prompting a user to input a keyword if the search button is found, clicking for searching and saving a result; if the error is not found, a message window pops up to tell the user that the execution has made an error. After all steps are converted into nodes, the RPA flow shown in fig. 2 is obtained.
Each node on the flow chart is provided with a control interface and a data interface, and as shown in fig. 3, the node of the 'setting text' is provided with a control input interface, a control output interface and a data input interface. Each node may have a control input interface and a control output interface and a plurality of sub-control interfaces. The main process is connected by using a control input interface and a control output interface, and the sub-processes are connected by using sub-control interfaces of the nodes. The data interface comprises a data input interface and a data output interface, and each node is provided with a plurality of data input interfaces and a data output interface.
Attribute values are also included in each node for representing the static and dynamic content of the RPA components. The attribute value is a key-value pair, such as "event type" = "mouse click", which means that the "event type" of the current node is "mouse click". The value corresponding to each key may be of a variety of data types, such as string, number, option. Taking the "set text" node in fig. 3 as an example, it contains attributes such as "window attribute", "target attribute", and the like, corresponding values are character strings, and belong to static content, and the "text" input by the user is also a character string type, and belong to dynamic content.
And S2, connecting the control interfaces of the nodes according to the sequence of the operation steps to realize the execution of the control flow.
The operation steps in the RPA process have an execution sequence, for example, a web page is opened first, then a button in the web page can be clicked, two nodes are created for the two operation steps respectively, and a control output interface of the node executed first is connected to a control input interface of the node executed later to obtain a control flow, that is, a connection line of the control interface represents the control flow.
When the control flow is executed, the execution is performed according to the sequence of the main flow, when a certain node in the main flow has a derivative sub-flow, the derivative sub-flow is executed, and after the execution is finished, the main flow is returned to execute the next node. In the RPA flow shown in fig. 2, there is a main flow, and there are sub-flows introduced by the "For loop" node and the "IF branch" node. The control output interface of the 'For circulation' node is connected with the control input interface of the 'message frame' node to represent the main flow; the sub-control output interface of the "For loop" node is connected with the "open browser" node to represent the sub-process, as shown in fig. 4. And after all the sub-processes of all the nodes of the For cycle are executed, returning to the main process and continuously executing the nodes of the message frame. The "IF branch" node contains two sub-processes, one sub-process being executed when the location element is successful and the other sub-process being executed when the location element is failed, as shown in fig. 5. Since the "IF branch" node has no next node, it is the last node of the sub-flow, and the current sub-flow ends after the execution is finished.
And S3, connecting the data interfaces of the nodes according to the data requirements of the nodes to realize the sequential circulation of the data flow.
After the control flow of the RPA flow is described by using the connecting line of the control interface, data flow between nodes can be increased, namely, the output data of the node can be used as the input data of a target node connected with the node; when the node corresponding to a certain step needs certain data, the node with the data is connected with the data interface of the node, so that the node can obtain the data needed by the node during operation.
As shown in fig. 6, the data output interface of the "input box" node is connected to the data input interface of the "set text" node, and indicates that the content input by the user in the previous step is to be transmitted as dynamic content to the "set text" node for changing the content of a certain element on the page.
After all the control interfaces and data interfaces of the nodes are connected correctly, the whole RPA process can execute all the steps in a desired manner and transfer data correctly.
Because the whole RPA flow is displayed in a diagram mode, the RPA flow can be clearly displayed on an interface no matter how many levels of nesting exist, and the RPA flow is very convenient to understand; in addition, since the data flow also has clear representation, the coordination through memory and common variables is not needed any more, and the data flow is easy to understand; such a representation can greatly reduce the learning and development costs of RPA developers.
