step 102, calling a file storage node in a node space of the OPC UA to log in a file management service unit, and controlling the file management service unit to receive and store a download file.
it is understood that in the embodiment of the present invention, the node space of the OPC UA needs to be constructed so as to provide the OPC UA standard interface based on the function implemented by the node space. The node space comprises data objects and method nodes for file management, wherein the data objects correspond to download files and the like, and the method nodes correspond to download services such as uploading, managing, storing and downloading methods of the download files. Based on the method, the node can log in the corresponding server to execute the method operation corresponding to the method node.

certainly, in actual execution, when a download file is uploaded to the file server, attribute information (including version information of the download file, upload time, and the like) corresponding to the download file in a node space in the file server is updated, when the attribute information of the download file in the node space is updated, whether the version of the download file is updated or not may be determined based on the attribute information, and if the version of the download file is updated, a download file update notification is actively sent to the download proxy node device through the OPC UA notification interface in the second OPC UA standard interface.
in the embodiment of the present invention, referring to fig. 2, a file server is used as a bridge for communication between a configuration server and a download proxy node device, the download service is implemented in the file server based on an OPC UA interface, the file server provides a first OPC UA standard interface for communication with the configuration server and a second OPC UA standard interface for communication with the download proxy node device, and uploading and downloading of a download file based on a unified OPC UA standard interface are implemented.
Specifically, after the download agent node device receives an update notification of the download file or finds that the download file has an updated version, a download request is sent to the file server based on the second OPC UA standard interface, so that, based on the node space of the OPC UA, a file download node corresponding to the download file request in the node space of the OPC UA is called, so as to log in to the file management service unit according to the file download node, control the file management service unit to execute a download method operation corresponding to the file download node, download the corresponding target download file from the file system, and feed back the target download file to the download agent node through the second OPC UA standard interface.
in the embodiment of the present invention, in order to implement the purpose of using the opua as a unified communication bus, the FTP server needs to implement user management, file access right management, and the like based on the OPC UA protocol, because the FTP server has a perfect user right management system in addition to implementing storage, upload, and download services of files, and can implement functions such as user management, file access right, and the like.
And secondly, the file management method of the rail transit-based integrated monitoring system is centralized on a file server to realize user management and file access authority management side description.
specifically, in an embodiment of the present invention, as shown in fig. 3, before calling a file download node corresponding to a download request in a node space of the OPC UA, the method further includes:
Step 201, obtaining the device information sent by the downloading proxy node device through the second OPC UA standard interface.
in order to ensure the security of the downloaded file and avoid the downloaded file being downloaded by an illegal downloading agent node device, the role of the downloading agent node device needs to be verified, that is, the second OPC UA standard interface is acquired to acquire the device information of the node device sent by the downloading agent node device, where the device information includes information uniquely identifying the downloading agent node device, such as the node device identifier of the downloading agent node device. The permission information may be synchronously sent when the download agent node device sends the download request.

And then, the file server calls an authentication node in a node space of the OPC UA to start an authentication management service unit so that the authentication management service unit authenticates whether the downloading proxy node equipment has downloading authority according to the prestored downloading authority information and equipment information, namely, whether the downloading proxy node equipment corresponding to the equipment information belongs to a downloading range is verified in the downloading authority information corresponding to the downloading file.
Step 203, receiving the authentication result notification fed back by the authentication management service unit, and if it is determined that the downloading proxy node device has the downloading authority according to the authentication result notification, allowing to call a file downloading node corresponding to the downloading request in the node space of the OPC UA.
specifically, after the authentication, the authentication management service unit feeds back the authentication result notification right result to the node space, so that after the node space receives the authentication result notification, it is determined that the download proxy node device has the download right, for example, it is determined that the authentication result notification includes identification information (the identification information may be a pre-calibrated identifier representing successful verification, or the like) for the corresponding download proxy node device, and the file download node corresponding to the download request in the node space of the OPC UA is allowed to be called, and the corresponding download file is downloaded.
In an embodiment of the present invention, after receiving the authentication result notification, if it is determined that the download proxy node device does not have the download authority, the file download node corresponding to the download request in the node space of the OPC UA is prohibited from being invoked, so as to protect the security of the download file, and the download prohibition notification is sent to the download proxy node device through the second OPC UA standard interface.
In addition, in practical application, the integrated monitoring system needs to provide functions such as file discovery, file version management, file content analysis, file type management and the like for file management besides the above functions, which are very important for the integrated monitoring system, but the FTP server cannot provide the above services, so that in the implementation of the invention, the functions of the FTP server are also expanded, and the functional deficiency of the FTP server in file management such as file analysis and the like is made up.
