1. Project Background
A city's highway management office needs to provide wireless coverage for major highways in the city in order to respond to sudden traffic accidents and daily patrol incidents. Through the wireless emergency video broadband private network transmission technology with the same frequency network and platform data information management and other high The effective integration of scientific and technological means means the construction of an efficient and stable highway wireless emergency video broadband network transmission system for the reasonable allocation of frequency bandwidth resources. A unified networked wireless image and data transmission system management and dispatching platform shall be established at the municipal and county highway bureaus, and the interconnection shall be realized by relying on the highway-specific information network. Each county shall establish a base station, a vehicle terminal, and a soldier system of a dedicated wireless data transmission system to realize two-way voice, Multimedia services, such as images and data, enable unified, all-IP network scheduling and management, interoperability, and meet the demand for visualized and flat command in key areas.

3. Deploy municipal wireless image transmission system management platform scheduling <br> <br> in the Council with the provincial management platform scheduling, networking and city-level network control platform via private network for remote management of the city's highway authority all mobile terminals And command scheduling. The municipal network management control platform consists of streaming media video server, network video data storage server, wireless emergency video command and dispatch platform and system management scheduling software, video codec on the wall, downlink video encoder, wireless emergency equipment management server (including GIS and It is composed of software, database, PSTN voice gateway, and voip phone system. It can connect with existing information systems such as the existing video conference system, PGIS system, and image networking platform of the municipal office.
(1) Streaming Media Video Server: Responsible for the forwarding of multimedia services such as images, voice, and data.
(2) Wireless emergency video command and dispatching platform: The dispatcher's operating platform is the window to implement the dispatch function. The dispatching desk can be a notebook or a desktop computer, configure scheduling management software, and provide a graphical operation interface. A dispatcher can drive multiple dispatchers. As long as all dispatchers are in one network and authorized, they can all perform service scheduling.
(3) Video codec: Complete functions such as coding and decoding of the image, and it can be connected to display video terminals such as large screens and video matrices.
(4) Network data storage server: network IP network video data storage, 2T data storage capacity, support TCP / ip, UDP, ONVIF protocol.
(5) Wireless emergency equipment management server/PGIS system: manages the working status, fault alarms, resource allocation, technical supervision and control of all wireless transmission equipments, all equipments have GIS function, and provide Beidou or GPS positioning information and clocks and other information in real time. , and real-time display interaction with device parameters on the platform map.
(6) H.264 video encoder: Downstream video network coding, support for TCP/IP, TCP, multicast, onvif protocol (7) PSTN voice gateway, voip phone system: establish the province's VOIP phone to achieve telecom landline via voice gateway and The mobile phones communicate with each other, interoperate with the VOIP phone of the municipal office and the VOIP phone of the wireless mobile vehicle-mounted terminal to realize the inter-communication between the vehicle and the vehicle. Each VOIP phone can communicate with the mobile phone and the mobile phone.
The network management platform interface standard and openness can integrate the mobile surveillance image with the existing fixed surveillance image management platform and geographic information system of the province*s institutions to form a “wide network monitoring system†for grid management.
4. Deploy district level wireless image transmission system management platform <br> <br> scheduled by the municipal and county special network, network management platform *-level management, both for remote management and command of the city's highway authority all mobile terminals Dispatch can also upload multimedia data from jurisdictions to the municipal office. District and county network management control platform consists of streaming media video server, network video data storage server, wireless emergency video command and dispatch platform and system management scheduling software, video codec on the wall, downlink video encoder, wireless emergency equipment management server (including GIS And the software, database, and voip telephone system are composed of the existing information systems such as the videoconferencing system, the PGIS system, and the image networking platform of the City Council. It is composed of other equipments, and can be connected with existing information systems such as the existing videoconferencing system, GIS system, and image networking platform of the municipal office. In the case of multiple base station networking, the municipal network management control platform must also ensure that all front-end devices automatically roam between multiple base stations and perform functions such as authentication, registration, and logout. (System functions and technical requirements are the same as those of municipal wireless image transmission systems. platform).
5.* Level NMS Control Platform
Prepare to deploy the * level wireless image transmission management and dispatch platform, which is composed of the municipal management dispatching platform networking, wireless emergency video command and dispatch platform and system management dispatch software, video codec on the wall, and voip phone system.
