Wireless image monitoring system based on 4G technology

Abstract

The invention discloses a wireless image monitoring system based on 4G technology. The system includes: an image monitoring device installed in a drone and a video transmission device installed in a ground center station; wherein, the image monitoring device includes: installed in a wireless The monitoring processor, satellite navigation unit, high-definition motion camera, and 4G wireless communication module on the man-machine; the monitoring processor uses a SOC single-chip multimedia processor as the core, with video input and output interfaces, audio input and output interfaces, video Analog-to-digital / digital-to-analog converter, storage and network communication interface; the video transmission device includes: a station-side 4G wireless communication module, a central station image processing module and a display terminal; the station-side 4G wireless communication module receives the machine-side 4G Image signal of the wireless communication module. The system uses a 4G wireless communication network to realize video transmission, which enhances the freedom and flexibility of video surveillance, improves work efficiency, and has low system cost and high security.

Description

technical field [0001] The invention relates to the field of image monitoring, in particular to a wireless image monitoring system based on 4G technology. Background technique [0002] At present, the videos taken by drones are generally transmitted to the ground station system through image transmission equipment, and then observers can view the videos taken by drones in real time on the ground base station, but due to the limitations of image transmission equipment and antennas , so that the distance between the location of the ground base station and the UAV must be within a certain range, so that the observer must follow the ground base station within this range, and if it leaves this range, the UAV cannot be viewed in real time The captured video has very large restrictions on its application. [0003] The key to realizing the UAV video transmission application lies in the wireless transmission link means. The current wireless transmission technologies mainly include ...

Problems solved by technology

However, the cost of these two technologies remains high, and their expensive initial construction costs and communication costs are often prohibitive and cannot be widely promoted.

[0005] WIMAX / WIFI and other technologies to build a wireless metropolitan area network for wide-area coverage video applications require the builder to build a large number of base stations. Due to the huge initial construction cost of the domain network, it is unwilling to share it with other users, thus causing a great waste of social resources

[0006] The fourth-generation mobile phone mobile communication standard refers to the fourth-generation mobile communication technology, foreign language abbreviation: 4G; this technology includes TD-LTE and FDD-LTE two standards (strictly speaking, LTE is only 3.9G, although it is It is advertised as a 4G wireless standard, but it has not been recognized by 3GPP as the next-generation wireless communication standard IMT-Advanced described by the International Telecommunication Union, so it has not yet reached the 4G standard in a strict sense
