Description
Technical Field
The invention relates to the field of warehouse logistics, in particular to an intelligent tray system capable of carrying out automatic warehouse-in and warehouse-out management.
Background
In the manufacturing and logistics industries, the entry and exit of raw materials and goods into and out of warehouses is a very common and frequent operation. The latter operation includes a plurality of specific operations such as picking, placing, loading, unloading, carrying, counting, checking and the like. At present, enterprises adopt a large number of equipment such as trays, automatic lifting forklifts, automatic stackers and the like, so that the operating efficiency of links such as taking, placing, loading, unloading, carrying and the like is greatly improved. However, in the links of statistics, verification and the like, the method still mainly depends on a manual or semi-automatic mode, and the efficiency and the accuracy are not very high.
After the goods are brought into the coding management, the counting and rechecking work of the goods in and out of the warehouse is correspondingly completed by a code scanning mode. Its advantages are clear knowledge about the goods in or out of warehouse, but one scan for each scan is needed in operation, and its speed is not increased. Failure to scan the code may occur if the printed quality of the coded label is poor, the label is smudged, or the brightness of the environment is insufficient when the code is scanned. If the goods are not placed in a good position or orientation, the coded labels are not visible, and the code cannot be scanned. Furthermore, in the case of code scanning, it is also possible to generate omissions.
A more advanced method is to install an RFID tag on the goods, and the code of the goods is written in the RFID tag as a supplement to the barcode or the two-dimensional code. When goods with electronic tags pass through a special door with an RFID reader during warehousing, the reader can read the information of the electronic tags in batches, and the system can finish warehousing and warehousing operations on the goods. Compared with manual operation and code scanning operation, the scheme has the advantages that the speed is greatly improved, and the identity of the goods can be identified. However, the RFID solution also has some drawbacks. For example, the distance between the tag and the card reader is required to be relatively short, the goods are required to be placed in a mode that the tag and the card reader are not shielded as much as possible, the goods cannot be placed too densely, metal substances cannot exist nearby the tag, and the like, otherwise, some tags cannot be scanned. In practical applications, incomplete scanning is also often found.

The pallet can be of various types made of wood or steel, aluminum, plastic and other composite materials for carrying goods for transportation and storage.
As shown in fig. 5, the MAC address of the intelligent terminal module needs to establish a one-to-one correspondence relationship with the code of the tray, that is, binding is performed, and the binding is performed through a dedicated intelligent device APP; the intelligent device APP is installed on the intelligent mobile phone with the Bluetooth 4.0 function and runs under an android system or an iOS system.
An intelligent tray application method for automatic warehouse-in and warehouse-out management comprises the following steps:
s1, mounting and fixing the produced intelligent terminal module on a tray in a screw, rivet or even viscose mode; the intelligent terminal module does not have a power-on key and a power-off key, starts working from the completion of production, and continuously transmits signal broadcasting at a certain frequency until the electric energy of the built-in lithium battery is exhausted;
s2, installing and deploying the in-site monitoring gateway in a factory area or a storage area, and ensuring that the communication range of the gateway can cover the positions of all in-site logistics monitoring machines;
s3, installing and deploying the logistics monitor in the yard on the pallet and the necessary passage for goods to enter and exit the warehouse according to the requirement, usually in the door of the warehouse or yard; according to the width of the gate of the warehouse or the yard, relevant parameters of the logistics monitor in the yard are adjusted, so that the monitoring range of the logistics monitor can just cover the width of the gate but is not too large. The parameter adjustment is completed through a smart phone supporting the Bluetooth 4.0 function.
S4, running a special APP to establish Bluetooth connection between the smart phone and the logistics monitor in the field, and writing specific parameter values into the monitor through the smart phone to adjust the scanning monitoring range of the monitor;
and S5, in the background management system, each in-site logistics monitor needs to be configured under a certain warehouse item, so that the system can identify which warehouse the tray information sent by the monitor belongs to. The code of the intelligent terminal module corresponding to each tray belongs to a certain warehouse item, and the state of the intelligent terminal module is marked as one of three states of ' warehouse in ', authorized warehouse out ' and ' on the way '. If the pallets are loaded with goods, the codes of the goods and the codes of the pallets are also associated in a background management system, and one code can be inquired by the other code.
S6, a mode selection switch is arranged on the logistics monitor in the site; the universal mode can simultaneously detect the warehousing of the tray and the ex-warehousing of the tray under a specific service scene. The tray warehouse-out has two scenes, and the difference is whether the trays can be determined to be warehouse-out before warehouse-out. Generally, when heterogeneous goods are delivered, which goods are to be delivered can be determined in advance. Since the goods and the pallets have corresponding relations, which pallets will be delivered from the warehouse can be determined in advance. In this scenario, the universal mode of the monitor is applicable. If the ex-warehouse plan is made and sent by an ERP, OMS or WMS system of a user, after plan data is imported into the intelligent tray management system, the system automatically marks the tray to be ex-warehouse as an authorized ex-warehouse state. The on-site logistics monitor sends broadcast information sent by the tray passing nearby to the background management system through the on-site monitoring gateway after receiving the broadcast information, the management system searches the state information of the tray in the system according to the received tray information, and if the tray is found to belong to the warehouse and the current state is authorized to be delivered out of the warehouse, the state of the tray is automatically changed to be in transit. If the pallet is found not to belong to the warehouse and the current status is "in transit", indicating that the pallet is being put in storage, the system automatically changes the status to "in-stock" and changes the warehouse to which the monitoring machine belongs. For other cases, the system does nothing. The warehouse-in/out judgment rule in the general mode is shown in fig. 6.
When the mode selection switch of the logistics monitor in the field is switched to the 'ex-warehouse mode', the monitor can only be used for counting the trays which are going out of the warehouse. This mode applies to scenarios where it is not possible to determine in advance which trays are going to be out of stock. If the user who operates the tray rental sends the trays to the client, the user only needs to ensure that the number of the sent trays is consistent, and does not specifically require which tray should be sent. Different from the general mode, in the ex-warehouse mode, for tray information scanned each time, the monitor sends mode switch data before sending the tray information to the background management system, and if the tray information is taken out of the warehouse as represented by '0', the current monitor is only used for ex-warehouse statistics. The management system searches the state information of the tray in the system according to the received tray information, and if the tray is found to belong to the warehouse and the current state is 'in-warehouse', the state of the tray is automatically changed into 'in-transit'. For other cases, the system does nothing. The judgment rule in the ex-warehouse mode is shown in fig. 7.
When the mode selection switch of the logistics monitor in the field is switched to the 'warehousing mode', the monitor can be only used for counting the trays being warehoused. The mode is suitable for various tray warehousing scenes. Different from the general mode, in the ex-warehouse mode, the monitoring machine sends mode switch data to the background management system before sending the tray information scanned each time, and if the tray information is sent to the background management system, the mode switch data is sent to the background management system, and the mode switch data represents warehousing by '1', which indicates that the current monitoring machine is only used for warehousing statistics. The management system searches the state information of the tray in the system according to the received tray information, if the tray is found not to belong to the warehouse and the current state is in the on-road state, the state of the tray is automatically changed into the on-road state, and the warehouse to which the tray belongs is changed into the current warehouse. For other cases, the system does nothing. The judgment rule in the binning mode is shown in fig. 8.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
