Why Car emergency communications base station is tethered UAV

2017-05-26

With the development of automotive technology, vehicle equipment has become more and more diverse, from the rear-view mirror, reversing radar to the development of reversing images, so that the development of the car to the UAV (an unnamed aerial vehicle). The earliest show is the February 2014 New Delhi Auto Show, released a concept car, equipped with four rotor unmanned aerial vehicles, that is, mobile communication base station. Usually automatically received in the roof, when needed, press the button will be able to lift operations. With built-in GPS and camera, the driver can control it via the tablet on the console or allow it to fly automatically. People who know UAVs know that this can only stay at the concept level, it is impossible to mass production.

But with the development of UAV technology, vehicle UAV communications base station began to reality. We all know that due to the geographical environment and climate diversity, in the face of a variety of sudden large-scale natural disasters, conventional emergency communication means often cannot meet the long-distance, voice, video and other communication requirements, especially in many disaster sites, due to terrain complex obstacles Electromagnetic wave propagation, making the emergency communication effect is more affected. Often the height of the antenna is one of the main factors that affect the coverage of wireless communication. The higher the antenna, the smaller the influence of the terrain on the propagation of electromagnetic waves, the more significant the improvement of the communication link quality. General vehicle emergency communication antenna height of not more than 10 meters, and often vulnerable to damage by the terrain damage, it is difficult to penetrate into the core area of the disaster. And the use of tethered UAV as an emergency communication base station, the function can be achieved for a long time off and equipped with communications equipment, the antenna or other communications equipment rise to become a tethered communication base station. It can better solve the complex terrain conditions of electromagnetic coverage problem, and effectively solve the conventional emergency base station of many drawbacks.

Tethered unmanned aerial vehicle equipped with emergency communication base station is a new means of communication, will be leased unmanned aerial vehicles as an emergency communications base station platform, with rapid deployment, light and flexible, low landing environment requirements, can achieve within a few kilometres Fast, reliable and stable broadband communication, in the sudden natural disasters, communications infrastructure is damaged, poor communication environment and other conditions, the emergency communications capabilities have obvious advantages. Compared with the large and medium-sized fixed-wing unmanned aerial vehicle and unmanned helicopter, the multi-rotor unmanned aerial vehicle emergency communication base station platform is small in size, light in weight, easy to carry, simple operation, low training requirements, low landing environment requirements, Maintenance is simple, flexible changes in flight status can be stable and so on, especially in the use of tethered technology, 24 hours a day time lagging in a certain area, to achieve a continuous emergency communications and communication protection.

Compared with other conventional vehicle emergency communications vehicles, car-based unmanned aerial vehicle emergency communications base station system even if the erection of the same location, as can be elevated to 200 meters high, the coverage can be extended to 30 km range; and because of its small size, Light weight, can be carried by the burden, airborne, etc. can be located in the vehicle cannot reach the disaster area, through the microwave link constitutes a communication relay node; and, in addition to communication capacity, but also equipped with video surveillance equipment, easy on-site emergency command use. The development and design of the system can drive the development of emergency communication base station technology in our country, and effectively solve the problem of lack of monitoring means of emergency response base station in China when faced with special natural disaster, and has significant economic and social benefits. Moreover, the fugitive unmanned aerial vehicle emergency communications base station system not only in disaster relief can play a huge role in the future in all areas of life will also be actively applied.
