Emergency communication system based on SKYWAN VSAT satellite communication network

Abstract

The invention discloses an emergency communication system based on an SKYWAN VSAT satellite communication network. The emergency communication system comprises a communication satellite transponder and a ground station with satellite regulator equipment; according to the emergency communication system, a wide-area transmission bearing network is constructed through a plurality of fixed ground stations and portable stations, so that a transmission platform covering a far-end field area and a rear command center is formed, and the emergency communication system is provided with an IP interface and is fused with any network based on the IP technology. The emergency communication system utilizes the characteristic of large coverage area of a satellite communication network to transmit on-sitereal-time videos, voices and data back to the rear command center to construct a transmission network between the rear and the front, thereby realizing command and dispatch communication in an emergency environment. In daily working conditions, the satellite communication network is used as a backup transmission network, a second route, a bearing part of communication services and the like, so that the bandwidth capacity of the whole communication system is increased.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an emergency communication network. Background technique [0002] At this stage, most of the power stations under the jurisdiction of the enterprise are located in high mountain and valley areas. When natural disasters such as earthquakes and mudslides occur, due to power outages, base station collapses, and optical cable breaks, the communication of the power private network is interrupted, thus delaying the precious time for disaster relief and rescue. , resulting in significant loss of personnel and property. [0003] During the "Wenchuan Earthquake" and "4.20" Lushan Earthquake, the public network was completely paralyzed, lacking the necessary emergency communication means, and unable to respond quickly and correctly. Therefore, the current communication network lacks the ability to deal with natural disasters and emergencies. When a serious disaster occurs, the disas...
