Embodiment 1,
As shown in fig. 1, an embodiment of a first aspect of the present application provides an intelligent warehouse logistics management system, the system comprising: the system comprises a warehouse-in module, a warehouse-out module, an inventory module, a visual library position management module and a data analysis module.
The warehousing module is used for receiving and inspecting quality of warehoused cargoes, then scanning and establishing a warehousing file based on PDA equipment, and inputting the warehousing file into a database; and conveying the goods to the appointed position, binding the warehouse-in information according to the warehouse-in label, and placing the warehouse-in goods from the warehouse-in direction.
The delivery module establishes delivery tasks according to requirements, delivers task information to the delivery terminal to complete scheduling instructions, and the delivery terminal forwards the task information to corresponding library positions and cooperates with the PDA equipment to complete scanning and delivery, and returns delivery success information after the delivery tasks are completed, so that the database is updated according to the success information.
When the operation of going out of the warehouse is needed, a job-out task is established, and the unmanned workshop management service issues an AGV (Automated Guided Vehicle, automatic guided vehicle) scheduling instruction according to the job-out task, and the AGV goes to a specified warehouse location according to a specified route to acquire goods and goes to a specified warehouse-out area. And in cooperation with the scanning and auditing of the PDA equipment, an alarm is sent out when an error occurs, so that a library manager can process the data in time, and finally the data is sent to a system to update a database to finish the library.
The scheduling instructions of the AGVs can confirm the optimal route according to the running states of all the AGVs in the current state, so that a plurality of devices are prevented from blocking a road, the road utilization efficiency is improved, and the running speed is increased.
The inventory module establishes inventory tasks, determines inventory ranges required to be checked, designates storage places, and inventory management staff checks the acquired inventory information with information in a database by using PDA equipment after entering information in the designated storage places to generate an inventory table.
The inventory task is generally the operation of regularly checking the difference between the actual content of the warehouse and the content of the database, and the operation needs to be completed manually.
And the visual library position management module binds the internal structure of the warehouse with library position label content in the database and establishes a corresponding relation between the plan and the database, so that any terminal connected to the system can be utilized to check the inventory information in different library positions in real time.
Through the corresponding relation of storehouse position and plan in the real-time supervision warehouse, can provide a safer swift route for storehouse management personnel shuttle in the AGV equipment that has the operation to the label on the arbitrary storehouse position of scanning can all let storehouse management personnel acquire goods relevant information, when the goods exists obvious unusual, the emergence of perception unusual that can be quick, thereby reduce the loss.
And the data analysis module establishes personnel operation conditions and stores inventory snapshot information regularly.
And (3) automatically storing snapshots of the inventory and changing conditions, particularly personnel operation content, which can provide data support for performance assessment and task amount adjustment.
In particular, in the actual use process of the warehouse, due to different use scenes, specific types of cargoes can have obvious differences, and small cargoes often need to be stacked in a plurality of quantities in one warehouse position so as to relieve warehouse pressure. At this time, by setting the warehouse-in direction and the warehouse-out direction on the goods shelf, the strict adherence direction of warehouse-in and warehouse-out is ensured, the goods overtime phenomenon can be reduced, and the inventory pressure is reduced.
Further, the warehouse-in direction and the warehouse-out direction may be two ends in the depth direction of the shelf, or may be two ends arranged in a left-right or up-down direction. The warehouse-in direction and the warehouse-out direction in the depth direction can enable the goods shelves to warehouse in and warehouse out to pass through the two directions of the goods shelves simply, so that the recording cost is reduced.

And B5, respectively confirming the corresponding relation between the RFID tag and the goods and the corresponding relation between the goods position and the RFID through twice signing, so that any information can be associated with corresponding inventory data content.
The steps ensure that commodities can not enter the warehouse to enter the storage rack in the process of being placed on the storage rack due to leakage, wrong storage rack and the like through primary unmanned signing when entering the warehouse and secondary signing when being placed on the storage rack. Meanwhile, if errors occur, the reasons of the commodity abnormality can be determined according to the time nodes and the specific states of the primary unmanned signing and the secondary unmanned signing, and the time cost of the later error correction process is reduced.
Third embodiment,
On the basis of the first embodiment, in order to perfect the function of the intelligent warehouse, a further limitation is now made, specifically as follows.
In the warehouse management process, the checking is an important step, and the traditional checking mode is manual, has strong limitation, and is time-consuming and labor-consuming.
When AGV is idle, in order to the labour of rational utilization AGV to solve the problem of taking a count time and energy, this application provides a thick mode of taking a count, and this mode includes:
and C1, the AGV confirms the region corresponding to the inventory task and the target library position through the system.
And the system establishes an area which needs to be checked through the checking task, and then sends the area to the corresponding AGV terminal.
And C2, taking out all the objects on the target library position in sequence, counting, generating an inventory list and uploading.
Because the performance and the cost of the visual equipment of the AGV are limited, the problem that whether the goods are damaged or not is out of date in the process of checking can not be confirmed when the goods label can be confirmed like eyes of people, so that the basic quantity checking can be only carried out.
And C3, placing the fetched articles back to the warehouse according to the fetching sequence.
And (3) returning the checked articles to the warehouse position according to the original sequence, so that the checked articles meet the first-in first-out principle in warehouse entry.
Based on the first embodiment, the second embodiment and the third embodiment, the basic circulation of the intelligent warehouse logistics management system of the application is explained, namely the flows of warehouse entry, warehouse exit and inventory.
In particular to automated handling equipment, i.e., AGVs, which participate in the system operation may be as shown with reference to FIG. 2.
