In the past, the installation of AGVs (Automatic Guided Vehicles) in warehouses or plants was difficult because plants are generally hard to wire for AGVs, or the wiring costs are too high. For these reasons, if your warehouse uses mobile equipment that is controlled over a TCP/IP network, or the cost of installing wire conduits at your work site is prohibitive, then setting up a WLAN (wireless local area network) is a good solution since plants already have Ethernet networks.
A wireless network is used for communicating between the AGVs and the primary workstation. The AGV runs on a circular rail, and by connecting the AWK-3121 as a wireless client to each AGV, the PLC inside the AGV can receive control signals from the primary workstation over the wireless network. The wireless clients connect with the warehouse network through an AWK-3121 configured as a wireless AP that itself links to the primary workstation.
For example, the AGVs can receive control signals from the control center to load goods. When the goods arrive at the warehouse, the AGVs can help transfer the goods from the inventory area to the delivery area. The primary workstation checks the inventory information and then arranges for the closest available AGV to carry out the transfer. Once an AGV is designated, the PLC inside the AGV sends the loading and delivery commands so that the AGV delivers the correct goods to a specific area. With industrial wireless technology, the AGVs can access the primary workstation, which provides inventory information for the control process.
WLAN technology is based on well-established IEEE 802.11 standards that include the popular standard known as Wi-Fi. The IEEE 802.11 standards have established a way to use radio frequency (RF) technology and send Ethernet packets over the air. The wireless network formed by the AWK-3121 wireless AP/Bridge/Client allows the AGVs to move about the dispatching area without compromising real-time communication requirements, and without needing to invest the effort needed to set up a wired solution. The wireless LAN that connects the primary workstation and the AGVs provides the right amount of flexibility for the warehouse automation system, and is the key to setting up a highly efficient warehouse automation system for your applications.
After installing the new system, the factory workers were able to transport products from the warehouse to the loading area much more quickly, and as a result, the factory has noticed a marked decrease in the time it takes to deliver products to resellers. Moreover, you can enhance the overall efficiency of your production facilities and warehouse operation.
