An agv call display and control system based on zigbee LAN

Abstract

The invention discloses an AGV (Automatic Guided Vehicle) calling display control system based on the ZIGBEE local area network. The system comprises a calling terminal module, a master control decision-making module, a ZIGBEE local area network module, an AGV vehicle-mounted control and communication module and an LED display module; the terminal calling module and the AGV vehicle-mounted control and communication module are connected with the master control decision-making module through the ZIGBEE local network area module; the LED display module is connected with a master control module. According to the system, ZIGBEE is utilized to perform wireless transmission, the system controls the AGV, and thus the AGV management labor is decreased, the conflict between management staffs is avoided, the AGV can be dispatched in sequence, the idling and waiting time of the AGV is decreased, and the production of a plant can be matched well; the ZIGBEE local area network applies to a complex electromagnetic space environment of the plant; an LED display screen can be used for displaying the state of the AGV.

Description

technical field [0001] The invention relates to the field of AGV automatic measurement and control, in particular to an AGV call display and control system based on a ZIGBEE local area network. Background technique [0002] At present, AGV (automatic guided vehicle) has become an important equipment in intelligent manufacturing, advanced logistics and digital factories. It plays a very important role in facilitating factory transportation and improving production efficiency. However, most factories now use single-vehicle AGVs for operation. However, when the route is more complicated and the number of AGVs is large, there may be an endless loop between the single-vehicles waiting for each other. [0003] For many large factories with large area and high noise, and the work stations are relatively orderly and require materials, if AGV is requested to transport materials, it is currently communicated through walkie-talkies and dispatched by AGV full-time administrators, which ...

However, most factories now use single-vehicle AGVs to operate. However, when the route is more complicated and the number of AGVs is large, there may be an endless loop between the single-vehicles waiting for each other.

[0003] For many large factories with large area and high noise, and the work stations are relatively orderly and require materials, if AGV is requested to transport materials, it is currently communicated through walkie-talkies and dispatched by AGV full-time administrators, which is very Inconvenient, the actual investigation found that the demand put forward by the station is difficult to meet, and the materials are not delivered early or late, which can easily cause the AGV to be idle or the station to wait for materials for a period of time; and it is difficult for the administrator to count and calculate the transportation of the AGV Therefore, the utilization rate of the AGV is very low; the manual call of the walkie-talkie is difficult to hear clearly in the noisy factory, and it is easy for the administrators to misunderstand and cause conflicts, and even delay the production of the factory.
