WCS is the abbreviation of Warehouse Control System, which is a layer of management control system between WMS system and PLC system. Warehouse Control System (WCS) is the foundation of warehouse informationization, realizes the integration of various equipment system interfaces, carries out unified scheduling and management of various equipment systems, coordinates the operation of various logistics equipment, such as conveyor lines, stacker cranes, shuttle cars, robots, automated guided trolleys, etc., and completes the tasks of warehouses in and out of the warehouse, and real-time monitoring and real-time tracking of task execution status of the equipment through real-time collection of equipment layer feedback. By collecting feedback from the equipment layer in real time, it can achieve real-time monitoring of the equipment and real-time tracking of the task execution status; WCS follows the principles of balanced load, shortest path, priority task, and blockage proximity in scheduling, and optimizes the combination of inbound and outbound tasks to achieve the best inbound and outbound double-cycle operation. In order to facilitate the operation of the user, WCS provides a simulation interface, which can reflect the real-time status of each device and the execution of tasks, and the user can operate intuitively according to their own authority. In addition, WCS also provides user operation authority group management, operation log, task execution record and equipment failure record and alarm functions.
