Autonomous traffic control method and device for AGVs and AGVs

Abstract

The invention discloses an autonomous traffic control method for AGVs. The autonomous traffic control method comprises the steps as follows: an AGV-A obtains an intersection identifier, and judges whether the AGV-A is in a control region or not according to the intersection identifier; the AGV-A transmits first traffic information to other AGVs through a short-distance communication module when judging that the AGV-A is in the control region; the AGV-A receives second traffic information transmitted by an AGV-B; the AGV-A obtains whether a line A and a line B have an intersection point or not when judging whether the AGV-B and the AGV-A are in the same control region according to the intersection identifier; and if the line A and the line B have the intersection point and the receiving time of the second traffic information is earlier than the transmitting time of the first traffic information, the AGV-A implements traffic control and stores the identifier of the AGV-B into an M region of a control pool. The autonomous traffic control method has the advantages that collision is avoided; and the running efficiency of the AGVs is improved.

Description

technical field [0001] The present application relates to the fields of communication and AGV, and in particular to an autonomous traffic control method and device for AGV and the AGV. Background technique [0002] AGV (English full name: Automatic Guided Vehicle, Chinese: Automatic Guided Vehicle) is a common industrial equipment. With the improvement of factory automation, AGV has also ushered in a big development. With the increase of the number of AGV, AGV in It is not a one-way channel. AGV has a cross channel, that is, a type of intersection. For modern traffic, traffic lights or other traffic control measures can be set at the intersection to avoid vehicle jams or collisions. But for AGV, It itself is a highly automated device, and it cannot effectively identify traffic lights, so how to carry out AGV traffic control has become a very important issue. [0003] In order to solve this problem, the existing AGV provides an integrated system, which mainly controls and lo...

But for AGV, It itself is highly automated equipment, and it cannot effectively identify traffic lights, so how to carry out AGV traffic control has become a very important issue

[0003] In order to solve this problem, the existing AGV provides an integrated system, which mainly controls and locates all AGVs in the factory building. This integrated system solves the problem of AGV traffic control to a certain extent, but With the improvement of plant automat
