no. 1 example

[0046] refer to figure 1 , this embodiment provides an AGV station task assignment system.

[0047] The AGV station task assignment system includes: a station configuration unit and a dispatching unit.

[0048] The site configuration unit configures attributes for the site.

[0049] In this embodiment, the station refers to the location point where the AGV needs to arrive and perform tasks. Generally speaking, the station is a part of the waypoints. Specifically, the AGV is in a To work in the warehouse, it is necessary to plan the movement routes of the AGV vehicles in the warehouse. These movement routes are generally called paths in this field, and the paths generally include way points and path lines, and the two ends of the path lines are path point, for example, the AGV walks from the gate to the storage registration office and then puts the goods into the shelf. This process may include several route lines and several route points, wherein the route points generally i...

no. 2 example

[0057] refer to figure 2 or image 3 , this embodiment provides an AGV station task assignment method, including the system described in the first embodiment.

[0058] It also includes: the dispatching unit receives the task request of the site, acquires the attributes of the site, searches for the site and assigns an AGV to the site to perform tasks.

[0059] The attributes of the site include initial weight, weight increment, weight increment interval, and maximum limit weight. When the site has a task that needs to be performed by the AGV, the site will send a task request to the dispatching unit, and the dispatching unit will receive the task request of the site and obtain the attributes of the site at the same time. In an embodiment, the scheduling unit simultaneously obtains the initial weight, the weight increment, the weight increment interval, and the maximum limit weight of the station; understandably, the The scheduling unit may also only first obtain the attrib...

no. 3 example

[0075] refer to Figure 4 , the embodiment provides an AGV station task assignment method, including the system described in the first embodiment.

[0076] The attributes of the site include an initial weight, a first changed weight, a second changed weight, and a maximum limit weight. When the site has a task that needs to be performed by the AGV, the site will send a task request to the dispatching unit, and the dispatching unit will receive the task request of the site and obtain the attributes of the site at the same time. In an embodiment, the scheduling unit simultaneously obtains the initial weight, the first change value weight, the second change value weight, and the maximum limit weight of the station; it can be understood that the scheduling The unit may also only obtain the attribute of the initial weight of the site first.

[0077] After the dispatching unit acquires the attributes of the site, it starts to search for the AGV for the site to perform tasks at the...

Abstract

The invention discloses an AGV station task allocation system and method, and the system comprises a station configuration unit which configures attributes for stations; a scheduling unit which is connected with the station configuration unit and is used for receiving the task request of the station and acquiring the attribute of the station, and searching and allocating the AGV to go to the station to execute the task. Attributes are configured for the stations, appropriate AGVs can be searched for tasks of the stations according to the attributes of the stations, the characteristics of the stations are better attached, and the AGVs can be better arranged to be matched with the tasks of the stations; Moreover, in the method for searching the AGV, a method of gradually increasing the search range is adopted, so that the probability of low efficiency caused by the difference of task time can be reduced.

Description

technical field [0001] The invention relates to the field of AGV vehicles, in particular to an AGV vehicle site task assignment system and method. Background technique [0002] AGV vehicle is an automatic guided handling device, which can realize unmanned operation in the working scene. In the existing AGV vehicle work scene, such as a warehouse, there are generally several AGV vehicles described above. In order to schedule and arrange the orderly work of several AGV vehicles described above, a scheduling system will be equipped. [0003] In the prior art, generally speaking, when the scheduling system receives a task from a site, it will assign the task to the AGV closest to the site (with the smallest weight). The site refers to the way point where the AGV stops during work. The task refers to the AGV dispatching system ordering the AGV to go to a certain site to perform actions (such as no action, picking up, releasing, charging, etc.). [0004] In practical application...
