Laser radar system based on wireless communication network and working method thereof

Abstract

The invention discloses a laser radar system based on a wireless communication network and a working method thereof. The laser radar system comprises an unmanned aerial vehicle, and optical assemblies, a laser emitter, a signal receiver and a data transmission assembly which are arranged on the unmanned aerial vehicle, wherein the optical assembly is located at the excitation end of the laser emitter and the receiving end of the signal receiver, the optical assembly comprises a spectroscope, a reflector and a displacement piece, and the displacement piece drives the spectroscope and the reflector to rotate so as to emit laser emitted by the laser emitter to a target object and emit a returned optical signal to the signal receiver. And the data transmission assembly transmits the optical signals received by the signal receiver to a central server through a wireless communication network. The technical problem that in the prior art, the signal receiving position is fixed, and consequently the returned light signal receiving capacity is poor is solved, and the technical problem that in the prior art, laser radar data cannot be transmitted and monitored in real time is solved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a laser radar system based on a wireless communication network and a working method thereof. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Airborne lidar optical scanning is a new type of active multi-sensor integrated complex system. The terrain model makes it have unique advantages in the fields of terrain surveying and mapping, digital city modeling, forest survey, disaster monitoring, environmental monitoring and so on. [0004] However, the inventors found that the traditional laser radar optical scanning is not stable enough when it is connected to the airborne, and it is easily affected by the flight angle of the fuselage during flight, which affects the overall scanning results, and the laser radar optical scanning i...

Problems solved by technology

[0006] In order to solve the above problems, the present invention proposes a laser radar system based on a wireless communication network and its working method. Through the rotation of the beam splitter and the reflector in the optical assembly, the laser emitted by the laser emitter is shot onto the target object, and the The returned optical signal is sent to the signal receiver, which solves the technical problem in the prior art that the signal receiving position is fixed and the receiving ability of the returned optical signal is weak; at the same time, the laser radar data is transmitted back to the central server in real time through the wireless communication network data transmission component, solving the problem of Technical problems existing in the existing technology that cannot transmit and monitor lidar data in real time
