A warehouse control system (WCS) provides interfaces with external systems (such as WMS), converts management operation plans into operation instruction formats and sends inbound and outbound operation instructions of corresponding storage locations to stand-alone equipment and conveyor systems. When WCS services are completed or failed to execute these instructions, it will provide feedback to external systems to receive real-time operation mode, status information, and alarm information of stand-alone equipment and conveyor systems, At the same time, the graphical dynamic display is displayed in the monitoring interface.
