Problems solved by technology

[0003] Lidar often needs to configure certain parameters. If the hardware program is changed every time, the efficiency is too low and the operation is inconvenient; In addition to the backend, it is also necessary to provide a man-machine interface to display the results in a friendly manner, which is convenient for viewing and analyzing the results

Embodiment Construction

[0025] The technical solution of the present invention will be further described in detail below in conjunction with specific examples, but the protection scope of the present invention is not limited to the following description.

[0026] Such as figure 1 Shown:

[0027] A laser radar control method, the method flow is as follows:

[0028] S1: Establish a UDP communication connection between the radar and the host computer;

[0029] S2: Continuously send UDP data packets to the radar in the LAN through the host computer;

[0030] S3: After receiving the UDP data packet, the radar sends a request to the upper computer to establish a TCP connection;

[0031] S4: After the TCP connection is established, the radar sends the device status to the host computer through the TCP connection;

[0032] S5: The host computer controls the radar or configures radar parameters through the TCP channel after receiving the device status data sent by the radar;

[0033] S6: The radar sends ...

Abstract

The invention relates to a laser radar control method, and the method flow is as follows: S1: establish a UDP communication connection between the radar and the host computer; S2: continuously send UDP data packets to the radar in the local area network through the host computer; S3: the radar receives the UDP data After the packet, send a request to the upper computer to establish a TCP connection; S4: After the TCP connection is established, the radar sends the device status to the upper computer through the TCP connection; S5: After the upper computer receives the device status data sent by the radar, it controls the radar or through the TCP channel. Configure radar parameters; S6: The radar sends scan data to the upper computer through the UDP connection. This solution is based on Ethernet and includes two types of connections, TCP connection and UDP connection. According to the characteristics of the two, TCP connection is used to transmit radar parameters, radar status and other information; UDP connection is only used to transmit scan data.

Description

technical field [0001] The invention relates to the field of radar, in particular to a laser radar control method. Background technique [0002] Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and speed of targets. Its working principle is to send a detection signal (laser beam) to the target, and then compare the received signal (target echo) reflected from the target with the transmitted signal, and after proper processing, the relevant information of the target can be obtained, such as Target distance, azimuth, height, speed, attitude, and even shape parameters, so as to detect, track and identify aircraft, missiles and other targets. It consists of a laser transmitter, an optical receiver, a turntable and an information processing system. The laser converts electrical pulses into optical pulses and emits them. The optical receiver then restores the optical pulses reflected from the target into electrical pulses and...
