Problems solved by technology

However, at some intersections where AGVs drive, due to the relatively large traffic volume, if there is no corresponding way to avoid traffic, it will lead to traffic jams or even collision accidents of logistics vehicles, which will easily cause damage to the logistics vehicles themselves, and even cause the vehicles on board to be damaged. material overturning

Embodiment 1

[0028] In order to solve the situation of intersection congestion and collision caused by the increase of traffic flow in the actual application scenario of AGV car, such as figure 1 As shown in the figure, the present invention proposes an intersection avoidance and passing method for AGV cars. The driving section of the AGV car is divided into intersection sections, passing sections, and waiting sections between intersection sections and passing sections. Passing an AGV mainly includes steps:

[0029] S1: Obtain the feedback signal during the movement of each AGV, and obtain the information of the road section where each AGV is located according to the feedback signal;

[0030] S2: When the AGV drives from the passing section to the end of the waiting section, determine whether there is an AGV in the waiting section in front of the current AGV. If so, control the front and rear AGVs to maintain a preset distance according to the feedback signal. If not, go to step S3;

Embodiment 2

[0050] In order to better understand the technical content of the present invention, the present embodiment describes the present invention by means of a system structure. image 3 As shown in the figure, an intersection avoidance and passage system for AGV cars. The AGV car travel section is divided into intersection sections, passing sections, and waiting sections between intersection sections and passing sections. The intersection section can only pass one vehicle at a time. AGV, the system mainly includes:

[0051] The signal acquisition module is used to acquire the feedback signal during the movement of each AGV, and acquire the information of the road section where each AGV is located according to the feedback signal;

[0052] The waiting section control module is used to control the front and rear AGVs to maintain a preset distance according to the feedback signal when the AGV enters the end of the waiting section from the passing section and there is an AGV in the wai...

Abstract

The invention discloses an intersection avoidance passing method for AGVs, and relates to the field of AGVs, and the method mainly comprises the steps: obtaining a feedback signal in the movement process of each AGV, and obtaining the information of a road section where each AGV is located according to the feedback signal; when the AGV is driven into the tail end of the waiting section from the passing section, the front AGV and the rear AGV are controlled to keep a preset distance according to a feedback signal when the AGV exists in the waiting section in front of the current AGV; and when the AGVs drive into the head ends of the waiting sections, the AGVs are controlled to be parked at the head ends of the waiting sections when the AGVs pass through the intersection sections, and when the AGVs do not pass through the intersection sections, the AGVs in the waiting sections are controlled to pass through the intersection sections according to the intersection passing sequence and the AGV priorities. According to the invention, through the arrangement of the passing section, the waiting section and the intersection section, different passing rules are set at different road sections, so that the AGV can pass through the intersection in order, collision caused by disordered passing is avoided, and through the setting of the priority, the AGV can be regulated and controlled according to the important transportation duration.

Description

technical field [0001] The invention relates to the field of AGV trolleys, in particular to an intersection avoidance and passing method for AGV trolleys. Background technique [0002] AGV (Automated Guided Vehicles) is also known as unmanned guided vehicle, automatic guided vehicle, and laser guided vehicle. Its distinctive feature is that it is unmanned. The AGV is equipped with an automatic guidance system, which can ensure that the system can automatically travel along a predetermined route without manual piloting, and automatically transport goods or materials from the starting point to the destination. Another feature of AGV is good flexibility, high degree of automation and high level of intelligence. The travel path of AGV can be flexibly changed according to changes in storage space requirements, production process flow, etc., and the cost of changing the travel path is the same as that of traditional conveyor belts. Very inexpensive compared to rigid transmission ...
