[0041] To more clearly illustrate the technical solution of the present invention, the accompanying drawings used in the technical description will be briefly introduced below.

[0042] Figure 1 This is an architecture diagram of the nuclear power cold source monitoring and integrated communication scheduling system provided by the present invention;

[0043] Figure 2 This is a schematic diagram of the nuclear power cold source monitoring fusion communication scheduling interface protocol provided by the present invention. Detailed Implementation

[0044] The following detailed description provides further details on specific implementation methods.

[0045] like Figure 1 As shown, this invention provides a nuclear power plant cold source monitoring and integrated communication dispatch system, including an integrated command and dispatch console, a signaling conversion module, a voice fusion module, a video fusion module, and a trunking dispatch module. This integrated communication dispatch system can connect to the integrated intranet via an integrated access gateway, enabling interconnection and interoperability between the dispatch console, smart terminals, and other devices and the integrated intranet telephone system.

The voice fusion module includes a PSTN conversion unit, a trunking conversion unit, and an audio conversion unit.

[0058] The PSTN conversion unit is used to convert traditional telephone channels such as PSTN lines, E1 lines, FXO, and FXS into SIP protocols.

[0059] The trunking conversion unit is used to convert trunking system calls, such as analog trunking, digital trunking, and broadband trunking, into SIP protocol.

[0060] The audio conversion unit is used to convert analog audio data into SIP protocol data.

[0061] The video fusion module merges video streams from different types of video devices to achieve video interoperability. The video fusion module includes a video access unit and a video conversion unit.

[0062] The video access unit connects different types of video devices through protocols such as GB28181, ONVIF, RTP, RTSP, and FLV.

[0063] The video conversion unit is used to convert videos with different encoding formats, resolutions, and bitrates into a unified format video and distribute them to the terminals in the system.

[0064] The cluster scheduling module provides scheduling applications such as group half-duplex intercom and multi-group intercom for mobile devices. The cluster scheduling module includes a cluster user management submodule and a cluster communication submodule.

[0065] The cluster user management submodule is used for managing multi-user groups, setting user permissions, and other related tasks.

[0066] The trunking communication module submodule provides users with functions such as half-duplex intercom, group switching, and priority intercom.

[0067] On-site personnel can wear AR smart glasses, which have voice and video call functions, enabling rapid connection between the front-end and back-end platforms and ensuring clear communication in the working environment. The AR glasses also allow back-end experts to send text and image information to the display screen through the management platform, and to mark areas on the display screen to guide front-end personnel in maintenance operations. On-site personnel can also wear head-mounted safety terminals to transmit on-site images back via WiFi network, freeing up the hands of front-end personnel and improving their work efficiency.

[0068] like Figure 2 As shown, the present invention also provides a nuclear power plant cold source monitoring fusion communication scheduling method, including the following:

[0069] The front-end IPC device registers with the GB28181 video platform. The media interaction protocols between the IPC device and the GB28181 platform include the GB28181 standard, ONVIF, RTST, etc.

[0074] The converged communication dispatch system supports audio and video dispatch functions, enabling unified dispatch and management of any mobile terminal or fixed video information. It can distribute and forward real-time video and images to any user within the system, truly achieving flattening and rapid collaborative sharing of video information. The system also supports cluster intercom dispatch functions, such as initiating cluster intercom and adding any member from outside the intercom group to the intercom group. The dispatch center is equipped with a dedicated intercom operator, which is convenient, fast, and efficient. The dispatch console, multimedia communication terminals, trunking intercom terminals, and fixed-line telephone terminals can establish groups or temporary groups as needed, and terminals within a group can communicate with each other. The system supports voice dispatching of terminals on wired and wireless networks. The current status of all terminals (e.g., standby, calling, called) can be viewed through the touchscreen dispatch console. Dispatch functions such as forced insertion, forced disconnection, monitoring, and recording can be performed through the dispatch console. Flexible grouping can be achieved through the dispatch console, enabling group broadcasting, mass messaging, and other functions. Handheld terminals can directly send instant messages such as text, pictures, and voice. Voice and video communication between mobile terminals within the application platform can be realized, with at least four channels simultaneously conducting voice or video conferencing. The application platform can interconnect with the power plant's administrative telephone system via E1 or SIP protocols, enabling voice communication between the application platform's mobile terminals and the power plant's production and office telephone system, and allowing short number dialing. The application platform can support a maximum telephone user capacity of no less than 1000, and can be expanded as needed.
