With the continuous progress of urbanization in China, urban construction and the continuous increase of population, social conflicts have become increasingly complex and acute, and the impact of various types of sudden disasters and incidents on cities has become more and more serious. Existing wired surveillance emergency systems can no longer meet the requirements for timely, mobile, and rapid on-site information collection, on-site disposal, and command management in the face of various emergencies.
As a result, various wireless monitoring devices, such as wireless network cameras, mobile individual soldiers, on-board command systems, and on-board systems, were quickly added to the emergency command system as an application of the emergency command system in mobile, rapid, and temporary scenarios. However, the existing public wireless network cannot meet the security, reliability, timeliness, and performance requirements of the security emergency system for the transmission system. Therefore, the establishment of a dedicated, controllable communication network can ensure that managers can provide the smoothest and most reliable emergency channel at a critical moment.
Development Development <br> <br> wireless private network of wireless private network is a voice application network from 1G to 4G voice, broadband data and development of high-definition video network, is a development from analog to digital, narrowband to broadband development process.
The rapid development of wireless digital broadband cluster technology provides excellent bandwidth environment and reliable technical support for high-definition surveillance video, multi-party voice calls, and digital service transmission. With the continuous improvement of 4G technology, the construction of transmission networks is faster, more secure and more feature-rich.
Advantages of wireless private network 1. Large service capacity: The capacity of a single group of groups is greater than 200 groups, and the number of online users is greater than 1200.
2. Efficient frequency utilization: uplink is greater than 3.5bps/Hz, downlink is greater than 6bps/Hz
3, a wealth of business support: At the same time for voice, data, video, cluster services to provide services 4, excellent transmission performance: uplink 50Mbps, downlink 100Mbps transmission bandwidth.
5, good anti-jamming capability: using inter-cell interference randomization and interference cancellation and interference coordination technology.
6. Efficient maneuverability: The mobile platform can be used to build a wireless emergency network at any time.
7, good visual performance: visual cluster scheduling, command center can watch high-definition surveillance images.
8, powerful security: support multiple encryption algorithms, so that voice, data, video security transmission.
9, strong compatibility: follow the BWT marked network system framework to guarantee the heterogeneous system see the interconnection and interoperability.
Emergency Wireless Network System Construction <br> <br> system uses a three-layer topology to achieve the following system functions:
1. The transmission system consists of individual soldier system, emergency command vehicle system and emergency command center system.
2. The individual soldier system completes the image collection of the accident scene and can carry out wireless transmission with the emergency command vehicle. 3. The emergency command vehicle and individual soldier system realizes one-way video transmission and two-way multi-party voice intercom.
4, emergency command vehicle through the wireless network and front-end soldier system for image transmission.
5. The emergency command vehicle realizes business transmission through the maritime satellite channel and the emergency command center.
6. The emergency command vehicle performs live local browsing and local storage of live images.
7. The emergency command vehicle selectively uploads live images according to the bandwidth of the maritime satellite channel.
8. The emergency command center will watch the live image in real time through satellites and issue command instructions to the site through voice.
9. The emergency command center can access live image stored in the emergency command vehicle in real time.
10. The emergency command center locates the position of the on-site personnel in real time through the GPS platform and issues instructions for personnel deployment.
Wireless Network System Description <br> <br> emergency scene image acquisition Individual wireless transmission device of FIG. The on-site personnel, through the camera deployed on the individual equipment, collected the scene and then compressed and encoded it through the individual equipment, and transmitted it to the emergency command vehicle through the private network through the wireless private network transmission module configured by the individual equipment. At the same time, the individual equipment and the emergency command vehicle realize two-way multi-party mixing and intercom. It can either make a call with the emergency command vehicle or conduct real-time talks with other on-site individual soldiers. To ensure mutual security and support between on-site personnel. The GPS positioning system and background GPS software platform configured by individual equipment can display the actual location of the front-site on-site support personnel in real time.
The emergency command vehicle serves as the core node unit of the entire field emergency command. The wireless transmission private network constructed by the system receives the on-site image uploaded from each individual soldier device. And through the multi-mix intercom function to the on-site personnel issued command instructions. Through the on-board display system configured, live images transmitted by individual soldiers are browsed in real time, and local network storage is performed. Through the configured car client, all images are displayed locally, searched, retrieved, and played back. Through the configured video management server, the on-site images and storage images that need to be uploaded are uploaded to the command monitoring center through the satellite channel of Maritime Satellite. Based on the bandwidth of the channel provided by Inmarsat, the uploaded image can be selected.
The emergency command center transmits the image transmitted by the emergency command vehicle through the maritime satellite through the satellite terminal equipment, performs local decoding and output through the local video management server and the streaming media server, and displays and outputs the image on the display system. And through the operation of the terminal's multi-remix system will be command command real-time under the emergency command vehicle and individual mobile terminal. Through the client software, the operator of the command center can perform real-time browsing and local storage of queries, retrieval and playback of all images through the network.
Combined with the background GIS system platform, a complete emergency command system can be formed.
