Technical field

The present invention relates to laser coherent control technologies and laser radar technique field, and in particular to one kind is phased based on laser The airfield runway foreign matter monitoring of battle array technology is monitoring system.

Background technique

The environmental requirement of airfield runway is stringenter, therefore, also excellent to be important for the cleaning work of airfield runway, for race The method that the investigation of road foreign matter is usually taken is as follows:

1, artificial scene investigation；Inspection personnel's walking is ridden at a slow speed along runway periodicity inspection.This mode is to the same as all the way The monitor check period of section is long, generally about more than dozens of minutes；And it cannot achieve real time monitoring.

2, mechanical image scanning；It proposes the regional scanning for carrying out airfield runway using camera, and then identifies whether to deposit In foreign matter tool rotation observation is not shut down, to continuous imaging interpretation in region due to using mechanical scan.The disadvantage is that long The problems such as time rotation work, it is easy to aging that there are mechanical bearings, and service life is short.Meanwhile there is also runway sun for camera imaging The problems such as light reflection interference and insufficient night illumination.

Summary of the invention

The present invention is to solve existing airfield runway by manually carrying out continuous inspection, walking or the modes such as inspection at a slow speed of driving, It is long that there are detection cycles, and using when camera scanning there are the service life it is short the problems such as, provide a kind of based on phased laser array skill The airfield runway foreign matter monitoring system of art.

Airfield runway foreign matter monitoring system based on phased laser array technology, including multiple information acquisition terminals and intelligence letter Cease processing system；

Each information acquisition terminal and intelligent information handling system pass through fiber optic communication；

The information acquisition terminal includes laser, phased laser array transmitting and receiver, controller, the first optical transmitter and receiver mould Block, two-dimensional adjustment bracket and power supply adaptor；The power supply adaptor is laser, controller, phased laser array transmitting and connects Receive device and the first optical transmitter and receiver module for power supply；The laser, phased laser array transmitting and receiver, controller, the first light end Machine module and power supply adaptor are fixed on two-dimensional adjustment bracket；

The intelligent information handling system includes computer workstation, the second optical transmitter and receiver module and UPS, and the UPS is to meter Calculation machine work station and the second optical transmitter and receiver module carry out anti-breaking electric protection；

Light source of the laser as phased laser array, the phased laser array transmitting is with receiver for scanning transmitting With reception return laser beam；

Controller controls phased laser array Laser emission, controls scanning speed and range；And it receives at the intelligent information The instruction of reason system and report send scan echo information；

The first optical transmitter and receiver module is converted for electric signal and optical signal, is believed between controller and computer workstation Breath transmission；

First optical transmitter and receiver module is also used to the electric signal of controller being converted to optical signal transmission to Intelligent Information Processing system The second optical transmitter and receiver module in system, the second optical transmitter and receiver module convert optical signals to electric signal transmission to computer operation It stands；

The computer workstation is collected for information and Intelligent treatment, and control instruction is sent, and warning information generates, foreign matter Position instruction is also used to for received information being transmitted to the controller of each information acquisition terminal；The computer workstation pair The information of each information acquisition terminal is collected and control, and uses image recognition algorithm, and identification airfield runway is abnormal.

Beneficial effects of the present invention: the present invention uses phased laser array technology, can uninterruptedly be scanned to runway, to same The monitor check period of a road section is short, most fastly can 1s it is primary.Specific advantage is as follows:

One, the present invention is using complete automatically controlled phased laser array optical scanning, non-scan mechanism, therefore bearing-free is worn.One After secondary property installation alignment, no longer need to adjust.Therefore, life cycle depends on the electrical module service life, and life cycle is long.

Two, monitoring system of the invention focuses on information, reduces distributed processing system(DPS) bring system complex Property.

Three, the present invention uses 1550nm wave band of laser, is human eye safe waveband；Meanwhile it will not be to airport radar, microwave etc. Signal generates interference.
