Description

A fast recovery system for mobile communication

technical field

The invention relates to the technical field of mobile communication, in particular to a fast recovery system for mobile communication.

Background technique

At present, the commonly used mobile communication signals are transmitted by ground relay equipment. When the ground relay equipment encounters major natural disasters (such as earthquakes, floods, etc.) At this time, due to the obstruction of ground traffic and other reasons, the vehicle-mounted communication equipment cannot reach the accident site immediately, so that the accident area and its communication with the outside world cannot be restored within a relatively long period of time, resulting in a large number of lives and property. unnecessary losses, the existing ground transfer equipment is bulky and needs special power supply equipment support, and the ground information network is connected through communication optical cables. In the case of major natural disasters (such as earthquakes, floods, etc.), large-scale communication signals are interrupted for a long time due to power outages and severe damage to communication optical cables, and the communication network cannot be restored for a long period of time.

Contents of the invention

In order to solve the problem of rapid recovery of mobile communication when large-area communication signals are interrupted due to natural disasters or man-made damage, the present invention provides an airborne mobile communication rapid recovery system, which can not only quickly and timely restore communication, And can identify the location of the signal source and conduct conference-style communication sessions.

The technical solution adopted by the present invention to solve the technical problem is: a mobile communication quick recovery system, including a terminal module, a transmitting module, a receiving module and an antenna feeding module. The output end of the terminal module is connected with the input end of the transmitting module, the output end of the transmitting module is connected with the input end of the antenna feed module, the output end of the antenna feed module is connected with the input end of the receiving module, and the output end of the receiving module is connected with the input end of the terminal module. The terminal module includes a multiplexer and a multiplexer, the transmitting module includes a modulator and a transmitter, the receiving module includes a demodulator and a receiver, and the antenna feed module includes a duplexer.

The multiplexer is connected to the modulator and the transmitter through the baseband, the transmitter is connected to the duplexer, the duplexer is connected to the receiver and the demodulator, and the demodulator is connected to the demultiplexer.

Beneficial effects of the present invention:

1. The present invention is relatively low in investment cost, safe and reliable, and the communication signal transfer platform is carried to the destination by flying equipment, so as to quickly restore the mobile communication network caused by the large-area communication signal interruption caused by the destruction of the ground mobile communication equipment.

2. The present invention integrates light-weight and small-volume terminal modules, transmitting modules, receiving modules and other transfer communication modules, which are small in size, light in weight, strong in function and easy to carry onboard, and can be encrypted, scheduled, and Group call, group call, and positioning information can also be used to track and lock airspace control and ground communication signals.

3. In the present invention, the flight equipment is placed in a space range of about 8,000 meters to 10,000 meters from the ground at the destination. In this space range, the system can receive and transfer ground mobile phone signals, and can effectively avoid lightning, typhoon, ice and snow and other climatic conditions Impact.
