Embodiment 1

[0036] The port environment in the embodiment of the present invention is such as figure 1 As shown, it includes a navigation lane 620, ground lights 630 located on both sides of the navigation lane 620, the ground lights 630 can control the color and frequency of the ground lights 630, and the port container unmanned vehicle 700 is located in the navigation In the road carriageway 620, the color or frequency display is controlled to display the outline of the navigation carriageway 620, and the navigation path can be obtained by collecting the image of the ground lights. The distance between the ground lights 630 is 5m, and the width is equal to that of the The width and turning capacity of the unmanned vehicle 700 are adapted.

[0037] The port environment in the embodiment of the present invention can also be as figure 2 As shown, it includes a loading area 100 and an unloading area 200. The loading area 200 is close to the quay crane 300, the freighter 400 is docked beside th...

Embodiment 2

[0050] Such as Image 6 As shown, the embodiment of the present invention provides a method for navigating a port container unmanned vehicle by using a port ground lamp, which includes the following steps:

[0051] S210: Receive ground lamp position information, ground lamp flickering color information, and ground lamp flicker frequency information;

[0052] S220: Collect a ground lamp image, analyze and obtain actual flicker color information and actual flicker frequency information;

[0053] S230: Compare the flickering color information of the ground lamp with the actual flickering color information, compare the actual flickering frequency information and the flickering frequency information of the floor lamp, when the actual flickering color information includes the flickering color corresponding to the flickering color information of the floor lamp and / Or when the actual flicker frequency information includes the flicker frequency corresponding to the flicker frequency informat...

Embodiment 3

[0057] Such as Figure 7 As shown, the embodiment of the present invention provides a system 800 for navigating a port container unmanned vehicle by using a port ground lamp, which includes a receiving device 820, a ground light control device 810, and a ground light 630. The receiving device 820 and the ground light 810 Connect with the ground light control device 810;

[0058] The receiving device 820 is used for receiving port container unmanned vehicle driving path information and port container unmanned vehicle identification information, and sending the port container unmanned vehicle driving path information and port container unmanned vehicle identification information to the ground light control Device 810; The ground light control device 810 is used to determine the location information of the ground light that needs to be flashed according to the driving path information of the port container unmanned vehicle, and determine the flashing color information and blinking in...

Abstract

The invention relates to a method for navigating port container unmanned vehicles by use of port ground lamps, comprising the following steps: acquiring travel route information of port container unmanned vehicles and identification information of the port container unmanned vehicles; determining position information of ground lamps needing to flash according to the travel route information of the port container unmanned vehicles; determining flashing color information and flashing frequency information of the ground lamps according to the identification information of the port container unmanned vehicles; and controlling the work of the ground lamps according to the position information, the flashing color information and the flashing frequency information of the ground lamps. Vehicles can be navigated efficiently, and the problem of route conflict is solved. The travel efficiency is ensured. The computing time of overall real-time monitoring and planning is reduced. The reliability of the system is ensured.

Description

Technical field [0001] The invention relates to the field of navigation control, in particular to a method for navigating port container unmanned vehicles using port ground lights, a system for navigating port container unmanned vehicles using port ground lights, and a port container unmanned vehicle Car control system. Background technique [0002] In the port environment, the transportation of containers conventionally requires man-powered trucks to carry them back and forth, which is inefficient and often waits in line, resulting in waste of resources; the existing automatic container trucks obtain real-time access through the combination of magnetic nails and inertial navigation The position and posture can reach the target position and reduce human intervention. However, in practice, the effect is not very satisfactory. It often appears that the truck will conflict with other vehicle paths during the path recognition and planning process, causing sudden emergency stop and ca...
