The method comprises the following steps 301-304:

301. and receiving a video conference request of a newly-built electric power emergency consultation of the conference initiating terminal, and creating a video conference room of the electric power emergency consultation according to the video conference request.

In the embodiment of the application, the conference initiating terminal can be a command terminal or an intranet terminal or an extranet terminal, but the command terminal can be used for receiving the video conference approval request of the conference initiating terminal after receiving the video conference request of the newly-built power emergency consultation, and can be used for newly-built the video conference room of the power emergency consultation.

302. And sending video conference invitations to at least one intranet terminal and a plurality of extranet terminals.

The plurality of external network terminals comprise at least two first external network terminals associated with the same first power area, and the at least two first external network terminals are used for shooting the first power area according to different shooting angles. For example, there are 2 first extranet terminals.

303. After at least one intranet terminal and a plurality of extranet terminals enter a video conference room, receiving a first video image sent by the at least one intranet terminal and a second video image sent by the plurality of extranet terminals.

After at least one intranet terminal and a plurality of extranet terminals enter the video conference room, the video images sent by the intranet terminals and the plurality of extranet terminals can be received, for example, a first video image sent by the intranet terminal is received, and a second video image sent by the plurality of extranet terminals is received.

304. And displaying the first video image in a first display area of a display interface, and displaying the second video image in a second display area of the display interface.

Generally, large-scale power enterprises all build autonomous internal networks, and an emergency command system of the power enterprises needs to support a plurality of terminal displays such as an intranet, the internet, an APN private network and the like. When emergency command works across multiple network segments, a power enterprise leader conducts command on a software system on an emergency consultation system with large screen frequency communication of an intranet, and emergency repair personnel on disaster sites and expert personnel of command parts at all levels need to conduct work on a software system of an Internet and PN private network. The video consultation works between them because the network segment is not available, and the emergency consultation cannot be performed. In the embodiment of the application, the first display area belongs to the display area of the first spliced display screen, the second display area belongs to the display area of the second spliced display screen, the first spliced display screen displays the video images transmitted by the intranet terminal, the second spliced display screen displays the video images transmitted by the extranet terminal, the data transmitted by the video images are not interacted, the audio and video communication of multiple network segments is not needed, the convenience of video communication is improved, and the risk of data leakage is reduced because the video data of the intranet and the extranet are independently displayed.

Further, the first and second tiled display screens are adjacent tiled display screens, and in order to make the first and second tiled display screens look the same as possible, the splice gap between the first and second tiled display screens may be less than 10mm. In other embodiments of the present application, an intermediate split display may be disposed in a split between the first split display and the second split display, where the intermediate split display may copy and display video images of the first split display or the second split display that are adjacent to the intermediate split display.

In order to avoid that the splice joint between the spliced display screens affects the image display quality of the video conference, in other embodiments of the present application, an isosceles trapezoid prism may be disposed at a splice joint between the first spliced display screen and the second spliced display screen, and light rays emitted to the splice joint are incident on the isosceles trapezoid prism; the isosceles trapezoid prism is used for changing the emergent direction of light, so that the included angle between the emergent direction of the light and the plane of the spliced display screen is larger than a preset angle. Through setting up isosceles trapezoid prism in the piece department between adjacent first splice display screen and the second splice display screen, the light that will be directed to the splice seam changes direction, makes emergent light can be as far as with splice display screen place plane perpendicular to prevent that light from overflowing the side of splice display screen after causing the influence to the display screen of adjacent another splice display screen, can overcome the discontinuous problem of adjacent splice display screen picture display, splice display screen's picture display quality when having further improved video conference room.

In some embodiments of the present application, the light beam emitted to the splice seam reaches the isosceles trapezoid prism at the splice seam, and the light beam is refracted through the upper bottom surface, the total reflection of the waist and the refraction of the lower bottom surface of the isosceles trapezoid prism in sequence, so as to change the emergent direction of the light beam. The upper bottom surface and the lower bottom surface of the isosceles trapezoid prism are parallel to the plane where the first spliced display screen is located. I.e. parallel to the display surface of the display screen of the command terminal. Therefore, light rays can be symmetrically emitted from the isosceles trapezoid prism, and the uniformity of display brightness is improved.

In some embodiments of the present application, the apex angle α of the loin-trapezoidal prism satisfies the following formula:

wherein n is the refractive index of the isosceles trapezoid prism, and thetax is the included angle between the light rays emitted to the splice gap and the upper bottom surface of the isosceles trapezoid prism.

It should be noted that, the display screen of the command terminal may be directly formed by splicing the first spliced display screen and the second spliced display screen, or may include more spliced display screens besides the first spliced display screen and the second spliced display screen, which may be specifically set according to an actual application scenario, and is not limited herein.

As shown in fig. 4, a schematic diagram of a display interface of a command terminal is shown, where a left side 401 is a first display area of a first tiled display screen, and a right side 402 is a second display area of a second tiled display screen. Because the first video image displayed by the first spliced display screen is the video image transmitted by the intranet terminal, the second video image displayed by the second spliced display screen is the video image transmitted by the extranet terminal, and the intranet terminal and the extranet terminal video are displayed in a spliced manner, the situation that the existing electric enterprise has an autonomous internal network is avoided, an emergency command system needs to support a plurality of network displays such as an intranet, the Internet and an APN private network, but a video consultation works because the network segments are not communicated, the situation of emergency consultation cannot be carried out, the consultation of the intranet and the extranet can be realized only by separate display, the communication of complex network segments is not needed, the video conference safety is ensured, the efficiency of the video conference is improved, and the application scene is widened.
