After sending instructions to the conveying equipment, the system cannot immediately assume that the goods have arrived. Device reception, start execution and execution completion are different states. WMS device docking needs to clarify the relationship between business tasks and device instructions, and reserve the position for manual takeover in case of exceptions.

How to arrange records and operations

Business tasks generate equipment instructions, record unique identifiers and expected goals. Equipment feedback advances tasks according to status, and repeated feedback does not deduct inventory repeatedly. Enter the verification process after a timeout. When canceling the business task, first confirm whether the equipment has been executed to avoid database cancellation while the goods are still being transported.

The equipment instruction should include the task number, cargo vehicle and target location, and the receipt should be associated with the original instruction. The successful receipt of communication and the actual completion of the equipment are different states, and the system cannot update the inventory in advance after the first receipt appears. Preserves the reason when a device rejects a mission, such as target occupation or unrecognized vehicle. Manual takeover needs to terminate or confirm the original command first to prevent the device from continuing to perform old tasks after recovery. After the acceptance of the simulated equipment is completed but the receipt is lost, check the status of the equipment again and check to confirm whether the inventory has been repeatedly deducted.

Specific scenarios that need to be checked

For example, if feedback is interrupted but the goods actually arrive at the station, the acceptance should check the task status after manual confirmation. Test error targets, duplicate completion notifications, and device rejection instructions. The page displays the difference between business status and equipment status, allowing warehouse personnel to know whether to check goods or communications.
