Example Embodiment

[0027] Example one:

[0028] See figure 1 , The AGV traffic control and dispatch method of the present invention includes a central control center, a data storage module, a number of AGVs and network path diagrams; a number of path points are discretely arranged in the network path diagram, and the connection of several path points forms the driving path of the AGV. The starting point and the target point of the AGV are selected in the path points. The AGV can reach the target point or directly to the target point through other path points from the starting point. The network path diagram includes the original path and detours of the AGV driving to the target point. As for the travel path, the same area where there are multiple AGVs or the intersection area of ​​multiple paths is the traffic control area, and the AGV can bypass the traffic control area to reach the target location through the bypass path.

Example Embodiment

[0044] Embodiment two:

[0045] The storage device of the present invention stores multiple execution instructions. When the central control center detects that there is an AGV in the network path map driving to the traffic control area via the original route, it needs to wait for other AGVs to drive first. The execution instructions are used for central control The center loads and performs the following operations:

[0046] a. The central control center retrieves and calculates the average travel time Ta of the AGV each time it passes through the traffic control area from the data storage module.

[0047] b. The central control center calculates the consumption time Tc of the sum of the time Tb for the AGV to wait for other AGVs to pass through the traffic control area and the average travel time Ta of the original route through the traffic control area.

[0048] c. The central control center calculates the travel time Tr of the detour path of the AGV.

[0049] d. By comparing the si...

Abstract

The invention relates to an AGV traffic control scheduling method and a storage device. The method comprises the following steps that a, a central control center calls and calculates the average driving time Ta of an AGV passing through a traffic control area each time from a data storage module; and b, the central control center calculates the time Tb for the AGV to wait for other AGVs to preferentially pass through the traffic control area and the consumed time Tc of the sum of the driving time mean Ta of an original driving path passing through the traffic control area; c, the central control center calculates the driving time Tr of the AGV driving bypassing the traffic control area; d, through comparison of the detour driving time Tr with the consumed time Tc, if Tr is smaller than Tc,the AGV drives on a detour path, and if Tr is larger than or equal to Tc, the AGV continues to drive on the original path. According to the AGV traffic control scheduling method, when the AGV is about to encounter traffic jam, the central control center calculates the consumed time Tc of the AGV passing through the traffic control area and compares the consumed time Tc with the AGV detouring timeTr, so that the AGV selects a path with short time consumption to reach a target place, and the AGV avoids a jammed road section as much as possible.

Description

technical field [0001] The invention belongs to the technical field of AGV traffic control, and in particular relates to an AGV traffic control scheduling method and a storage device. Background technique [0002] AGV is the abbreviation of Automated Guided Vehicle, also known as AGV trolley, which refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along the prescribed guidance path, with safety protection and various transfer functions, industrial applications A truck that does not require a driver. Because AGV has the advantages of high intelligence, fast transportation speed, and space saving, its application range is becoming wider and wider. [0003] When the AGV is transporting goods, it often meets other AGVs at intersections. At this time, it is necessary to reasonably control the running sequence of the AGVs through the traffic dispatching system to avoid collisions of the AGVs. The traditi...
