The invention relates to the technical field of warehouse management, and discloses a data communication method, device, system and apparatus and a storage medium. The method comprises the steps that:when it is detected that a warehouse management system initiates a data communication request to a warehouse control system, a connection interface developed by an MINA framework is called, a long connection communication link between the warehouse management system and a warehouse control system is created, wherein the long connection communication link comprises a communication manager, a filter chain and a logic manager; whether the warehouse management system has to-be-interacted data or not is monitored in real time based on the communication manager; if so, to-be-interacted data are obtained, and the to-be-interacted data is encoded and decoded by utilizing the filter chain, so that a shelf control instruction set can be obtained; and logic processing is performed on the shelf control instruction set through the logic manager to obtain a flow data packet, and the flow data packet is sent to the warehouse control system through the communication manager. Through the method, the loss caused by the communication problem can be reduced, and the efficiency and quality of the business process are improved.
