Detailed Description
The invention provides a high-safety real-time remote operation and maintenance virtual display system for a power station, which can be implemented in such a way that the system comprises an HTTP server of a safety communication server, a VR server serving as a virtual display server, a VR terminal serving as a virtual display terminal and a switching station (namely the power station) communicated with the HTTP server; one embodiment may be that the system includes an HTTP server that is a secure communication server, an AR server that is a virtual display server, an AR terminal that is a virtual display terminal, and a switching station (i.e., a power station) that communicates with the HTTP server; one embodiment may be that the system includes an HTTP server that is a secure communication server, an AR server and a VR server that are virtual display servers, an AR terminal and a VR terminal that are virtual display terminals, and a switching station (i.e., a power station) that communicates with the HTTP server. The several embodiments are systems constructed based on VR technology or AR technology, which are substantially the same in system construction concept, and those skilled in the art can obtain system structures of another embodiment according to the system structures in one embodiment without any creative effort, so that the following only describes details of the system constructed based on VR technology.
As shown in fig. 1, the high-security real-time remote operation and maintenance virtual display system for a power station includes an HTTP server, a VR terminal, and a switching station (i.e., a power station) in communication with the HTTP server.
The HTTP server does not comprise an active communication device for actively connecting and communicating with the power station, and only comprises a passive receiving device for receiving actual operation data sent by the power station according to a communication protocol, so that a communication request cannot be actively initiated to the switching station, and only the actual operation data of the switching station can be received according to the HTTP protocol. The actual operating data reflect the state of the devices of the switching station, including state information data and state change data: the state information data is periodically sent by the switching station and reflects the current state data of all equipment of the power station; the state change data is transmitted by the power station in real time when detecting that the equipment state changes, and reflects the change of the equipment state. If the actual operation data only comprise the state information data, an HTTP server without an active forwarding function can be selected, the VR server periodically and actively acquires the state information data from the HTTP server, and if the actual operation data comprise the state information data and the state change data, the HTTP server with the active forwarding function needs to be selected. In order to enable the VR server to update the VR image (i.e. the virtual display image) in time, in this embodiment, the actual operation data includes state information data and state change data, and the HTTP server has an active forwarding function.
And the VR server acquires the actual operation data from the HTTP server and generates a VR image according to the actual operation data. The VR server includes a processor and a computer readable storage medium, and execution of a computer program stored on the computer readable storage medium by the processor performs the steps of: and actively acquiring actual running data of the last period from the HTTP server after starting to generate an initial VR image, and continuously receiving the actual running data sent by the HTTP server to update the VR image. Specifically, the VR server includes a data obtaining unit and an image generating unit, where the data obtaining unit is configured to obtain actual operation data, and check whether a device corresponding to state information data (or state change data) in the actual operation data is recorded in a device list according to the actual operation data, if so, send the state information data (or state change data) of the device to the image generating unit, and if not, save the state information of the device; the image generating unit is used for searching an image corresponding to the current state of the equipment in a pre-stored image according to the received state information data (or state change data) of the equipment, and generating an initial VR image or updating the VR image according to the image. One HTTP server can be connected with a plurality of VR servers, one VR server can be connected with a plurality of VR terminals, and the VR servers are deployed near the VR terminals due to the fact that the information transmission quantity between the VR servers and the VR terminals is large.
The VR terminal obtains and displays a VR image, and the VR terminal in this embodiment may adopt a common VR terminal on the market at present.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
