Description

Technical Field

[0001] This utility model belongs to the field of satellite communication technology, specifically relating to an emergency communication system based on a flat-panel satellite antenna. Background Technology

[0002] In emergency situations such as natural disasters and sudden incidents, traditional ground emergency rescue communication centers are usually based on emergency communication vehicles. However, emergency communication vehicles typically have the following drawbacks: On the one hand, emergency communication vehicles suffer from low timeliness and low accessibility: large-scale natural disasters may lead to inaccessible roads and traffic congestion. In cases of severe flooding, waterlogging, or poor road conditions in high-altitude and hilly areas, emergency vehicles may be unable to penetrate deep into the disaster area, making it difficult to quickly reach the rescue site to ensure hardware communication and delaying rescue efforts. On the other hand, emergency communication vehicles have a small mission radius: the deployment of ground-based emergency communication vehicles is limited by terrain and other factors. In mountainous and other complex terrain areas, signals are easily blocked, making it difficult to effectively cover the disaster area and meet the needs of emergency communication.

The rope winding mechanism 500 drives the cargo component 300 to move vertically below the flight component 200.

[0015] The ground command and control module 100 is used to control the flight component to fly over the target area and to control the rope winding mechanism 500 to lower the payload component 300, which is equipped with a flat-panel satellite antenna 400, to any flat surface within the target area. Figure 3 The ground command and control module 100 includes a command sending unit 110 controlled by buttons and a remote communication unit 120.
