A picking station, such as the picking station of fig. 1, may also be provided on the main conveyor line of the roller conveyor line for picking articles for shipment from the warehouse.

In the embodiment of the invention, the WMS can set the object counting task according to the requirement and issue the object counting task to the WCS after the object counting task is triggered so as to execute object counting. The item count may specifically include a cycle count and a pin count. The circulation checking refers to checking the articles in all unit containers in the warehouse, and the circulation checking task can be set to be executed without normal operation time, such as at night, so as to improve the overall operation efficiency of the warehouse. The dynamic pin counting refers to dynamic counting of unit containers which are picked out of stock, namely, counting of unit containers which are only picked out of stock and reduced in stock. The item inventory tasks may include a cycle inventory type and a pin inventory type. The WCS may be provided with a transportation facility control system, a transportation control system, an identification facility control system, an inventory station control system, a picking station control system, and the like.

An embodiment of the present invention provides a method for checking an article, which may be performed by WCS, as shown in fig. 3, and includes:

s301: receiving an object checking task of a target warehouse, acquiring storage information corresponding to the object checking task, generating and issuing a conveying task based on the storage information, and enabling conveying equipment to convey containers in all storage positions to a conveying line.

Wherein the container identification of each container and the item information, i.e. the first item information, within each container can be identified by the identification device as the container is moved along the conveyor line.

After the WCS receives the object checking task, the WCS may determine the type of the object checking task. In the embodiment of the invention, the type identifier can be configured in the object counting task to represent the counting type of the object counting task, and when the type of the object counting task is the dynamic pin counting type, the object counting task can be further configured with a warehouse-out object, such as a warehouse-out order, so as to determine the object of the object counting. After the WCS receives the object counting task, the WCS may determine the type of the object counting task based on the type identifier therein. If the type of the object counting task is a circulation counting type, the object to be counted corresponding to the object counting task is all containers in the warehouse; if the type of the object counting task is the movable pin counting type, the container for placing the objects can be inquired based on the ex-warehouse objects in the object counting task, and then the object corresponding to the object counting task can be determined.

After the WCS determines the object to be checked based on the object checking task, the storage information corresponding to the object checking task, namely the storage information of the object to be checked, can be queried. Because the object checking is executed through the identification equipment arranged on the conveying line, the container checked by each object checking is conveyed to the conveying line, and after the storage information corresponding to the object checking task is acquired by the WCS, the corresponding conveying task can be generated based on the storage information and sent to the conveying equipment, so that the conveying equipment conveys the container on the storage to the conveying line. The identification equipment can be arranged on the conveying line, and can scan the label on the container and the label of the article in the container, so that the container identification and the article information of the article in the container, namely the first article information, can be identified.

As shown in fig. 1, the identifying device and the picking station for delivery are provided on the main conveyor line, and the transporting device may transport each container to the main conveyor line. The main conveying line can be provided with a delivery buffer storage position (such as a picking delivery buffer storage position in fig. 1), the WCS can issue a transport task to schedule transport equipment to transport each container to the delivery buffer storage position, and the delivery buffer storage position is connected with the main conveying line, wherein the containers can be moved to the main conveying line. If the type of the object checking task is a movable pin checking type, all the containers need to be picked and checked out first, so that the containers need to be moved to a picking station on a conveying line, the picking station can pick all the containers so as to carry out object checking, all the containers can be moved along the conveying line after being picked, and can be scanned and identified by an identification device when passing through the identification device. The identification device may send the container identification and item information for the items within the container to the WCS after identifying them.

S302: and receiving the identification result of each container sent by the identification equipment, and inquiring the second object information corresponding to each container from the object inventory task based on each container identification.

The container label and the first article information in the container identified by the identification device are identification results, and can represent article information placed in the current container, and the article checking task can include article information in each container of the historical record, namely second article information.

S303: and matching the identification result of each container with the query result to obtain a corresponding matching result so as to generate and send the inventory task result.

In the step, the first article information and the second article information of each container are matched, namely whether the articles currently placed in the containers are consistent with the articles placed in the containers in the history record or not is judged, the corresponding matching result of the containers is obtained, and further inventory of the articles in the containers is achieved. The matching result corresponding to the container may include that the first item information is consistent with the second item information, and that the first item information is inconsistent with the second item information.

In this step, the above-mentioned determination needs to be performed for each container, that is, it is determined whether the first article information in the container is identical to the second article information corresponding to the container. If yes, the current placed article of the container is consistent with the article placed in the container in the history record; if not, the fact that the currently placed article of the container is inconsistent with the article placed in the container in the history record is indicated, and at the moment, the difference between the first article information in the container and the second article information corresponding to the container, such as information of multiple articles, fewer articles and the like, can be stored so as to facilitate verification. After each container completes the judging process, the results of each container can be summarized to generate the checking task result and sent to the WMS.

The container can be moved along the conveying line after passing through the identification equipment, and after the WCS can obtain the matching result corresponding to the container, the checking is completed, and then each container can be put on shelf again. In the embodiment of the invention, the buffer storage bits can be set so as to buffer the containers which need to be put on shelf, and as the corresponding matching result is that the containers of which the first article information is inconsistent with the second article information need to be checked, the corresponding matching result is that the containers of which the first article information is consistent with the second article information do not need to be checked again, different buffer storage bits can be set to place the containers corresponding to different matching results. Specifically, in the embodiment of the present invention, a container with a matching result corresponding to the first article information and the second article information being consistent may be set up, and a container with a matching result corresponding to the second article information being inconsistent with the first article information may be set up, as shown in fig. 1, where the first cache bit may be an on-shelf warehouse-in cache bit, and the second cache bit may be an inventory difference on-shelf cache bit. After the WCS obtains the matching result corresponding to the container, the buffer storage position corresponding to the container can be determined based on the corresponding matching result, so that the moving instruction corresponding to each container is generated and issued, and the container is moved to the corresponding buffer storage position along the conveying line for placement.

It should be noted that, as shown in fig. 1, the conveyor line includes a main conveyor line and an auxiliary conveyor line, and paths of moving the containers to the buffer storage locations along the main conveyor line and the auxiliary conveyor line may be different, so that in order to save moving paths of the containers, the WCS may select a path with a shortest distance for moving the containers. Specifically, after determining the corresponding buffer storage position of the container for each container, the WCS may obtain the current position of the container and the position of the corresponding buffer storage position, further determine the moving paths of the container reaching the corresponding buffer storage position along the main conveying line and each auxiliary conveying line, respectively, calculate the distance of each moving path, so as to select the moving path with the shortest distance from the moving paths, determine the moving path as the target path, that is, the moving path of the container, further generate a moving instruction based on the target path and send the moving instruction to the container, so that the container moves to the corresponding buffer storage position along the target path, reduce the moving distance of the container, and save the moving time and cost of the container.

In the embodiment of the invention, for the container with the corresponding matching result that the first article information is consistent with the second article information, the container can be put on shelf to the original storage position without rechecking, so after the moving instruction is issued, the container identifier of the container included in the slow storage position (such as the first slow storage position) can be acquired, so as to inquire the corresponding storage position information, namely the original storage position information of the container, further generate a put-on task based on the inquired storage position information, and send the put-on task to the carrying equipment, so that the carrying equipment puts the container included in the slow storage position on shelf to the original storage position of each container.

For the container with the corresponding matching result that the first article information is inconsistent with the second article information, the container can be put on a shelf to the empty storage position of the warehouse because the subsequent rechecking treatment is needed, and the empty storage positions are equivalent to the isolated storage positions for temporarily storing the container with the corresponding matching result that the first article information is inconsistent with the second article information. Because the containers need subsequent rechecking treatment, the objects in the containers are usually not discharged, and the discharged containers are usually carried to a preset discharging buffer storage position before discharging when the containers are discharged from the warehouse, in order to facilitate the discharging operation of other containers, the empty storage positions far away from the discharging buffer storage position in the warehouse can be selected to place the containers in the embodiment of the invention. Therefore, for the container in the second cache storage position, at least one goods shelf with an empty storage position in the warehouse can be firstly inquired, and then the horizontal moving distance from each goods shelf to the preset delivery cache storage position of the transportation equipment is calculated, so that each goods shelf can be sequentially determined to be a target goods shelf based on the order of the horizontal moving distance from the big to the small, and the task of loading the goods shelf is generated and issued based on the storage position information of the empty storage position in the target goods shelf, so that the transportation equipment loads the container included in the second cache storage position to the empty storage position in the target goods shelf until the second cache storage position is empty.

Specifically, a calculation formula for determining the target shelf may be shown in formula 1.

（1）

Wherein m represents a roadway identifier in the warehouse; n represents a shelf identifier in a warehouse;

indicating that an empty storage position exists on the shelf n, namely, putting the container in the second slow storage position on the shelf; />

Indicating the cache bit i; />

The horizontal movement distance of the transport facility from the shelf n located in the lane m to the delivery buffer i is indicated.

It should be noted thatAs shown in FIG. 1, when the shelves are arranged on both sides of the roadway, the shelf distances on both sides are equal to the shelf distance of the same shelf buffer storage position i, namely

. When a plurality of empty storage positions exist on the same goods shelf, in order to facilitate the container in other storage positions to be delivered out of the warehouse, the high-rise empty storage position of the goods shelf can be preferentially selected to serve as an isolation storage position to place the container in the second cache storage position; the storage bits in the shelf are usually numbered, and the smaller the number is, the farther the storage bits are from the warehouse-out buffer storage bits, so that the empty storage bit with the smallest number in the shelf can be preferentially selected as the isolation storage bit in the step.

As shown in fig. 1, each shelf corresponds to a tunnel in which the transport device moves, so that in order to make the transport device work uniformly in each tunnel, in the embodiment of the present invention, a threshold value of the number of shelf containers on each tunnel may be set, that is, the shelf in each tunnel may be used as a threshold value of the number of isolation storage locations. And screening out a number threshold number of empty storage bits from each roadway to serve as isolation storage bits (the number threshold number is 5, then each roadway can firstly select 5 empty storage bits to serve as isolation storage bits), after the number of containers put on the shelf in the roadway reaches the number threshold, determining that the empty storage bits in the shelf of the next roadway are put on the shelf until all the roadways are uniformly put on the containers in a second buffer storage bit with the number threshold number, and then carrying out second round of put on the shelf. Specifically, the steps of sequentially determining the shelf as the target shelf based on the order of the horizontal movement distance from large to small, so as to generate and issue the shelf loading task based on the container included in the hollow storage position of the target shelf and the second cache storage position can be specifically performed as follows: 1) Sorting the shelves based on the order of the horizontal movement distance from large to small, and determining the shelf in the first order as a target shelf; 2) Inquiring the number of the shelves on the roadway corresponding to the target shelf, and judging whether the number of the shelves on the roadway is larger than a preset number threshold; if yes, updating the shelf sequentially positioned at the rear of the target shelf into the target shelf; if not, determining the empty storage position with the smallest number in the target storage rack as a target storage position, generating and issuing a loading task based on storage position information of the target empty storage position, loading one container in the second slow storage position to the target storage position by the transportation equipment, and updating the loaded number of the corresponding roadway of the target storage rack, wherein the loaded number is increased by 1; and (2) circularly executing the step 2) until the second cache bit is empty.

After each shelf in the sequence is used as the target shelf to execute the above procedure, if the second buffer storage bit is not empty, the shelf including the empty storage bit in the warehouse may be rescreened to execute the above procedure to put the container in the second buffer storage bit, and meanwhile, the number of put-in-shelf corresponding to each lane is updated to 0. The number threshold may be set based on the number of transportable containers, for example, may be set to an integer multiple of the number of transportable containers, and if the number of transportable containers is set to 5, the number threshold may be set to 5, 10, 15, or the like. After the second buffer storage bit is empty, the number of the corresponding shelve of each roadway can be updated to 0, so that the next shelve can be conveniently used.

In the embodiment of the invention, when the object is checked, the container can be carried on the conveying line by issuing the carrying task, the container can pass through the identification equipment when the conveying line moves, the identification equipment can identify the container and the object information in the container and return the identification result, and the identification result is matched with the stored container identification and the object information corresponding to the container, so that the object checking result can be obtained, and the object checking is realized.

After the WCS sends the checking task result to the WMS in step S302, the WMS may generate a checking task for the containers whose corresponding matching result is inconsistent with the first article information and the second article information in the checking task result, and send the checking task to the WCS, so that the WCS performs checking on the containers. The following describes the execution flow of the review inventory task specifically with reference to the embodiment shown in fig. 3, and as shown in fig. 4, the method includes:

s401: receiving a rechecking and checking task, acquiring the information of the container to be rechecked in the rechecking and checking task, inquiring the storage information corresponding to the information of the container to be rechecked, and generating and issuing a new conveying task, so that the conveying equipment conveys the container to be rechecked onto a conveying line.

When the containers to be checked move along the conveying line, the container identification of each container to be checked and the third article information in each container to be checked are identified through the identification equipment, and the checking task is generated based on the checking task result.

The checking and counting task is generated based on the checking and counting task result, so that the checking and counting task can comprise container information, such as container identification, of a container with inconsistent first article information and second article information, which are corresponding to the matching result in the checking and counting task result. After the WCS receives the checking task, the information of the container to be checked in the checking task can be obtained, and then the storage information corresponding to the information of the container to be checked can be queried, and at the moment, if the container to be checked is put on shelf to the isolated storage, the storage information corresponding to the information of the container to be checked represents the isolated storage information of the container to be checked. The WCS generates a new conveying task for the container to be checked and sends the new conveying task to the conveying equipment, so that the conveying equipment conveys the container to be checked to the conveying line.
