Specifically, in the management and control method provided by the embodiment of the present invention, the empty card management and control reference information table is a basis for empty card management and control judgment, and accuracy of the definition data in the empty card management and control reference information table is an important reference basis for ensuring the quality of the implementation result of the management and control method. The following table schematically lists some information of the empty card management control reference information table, and the above steps S102 and S103 may be implemented in combination with information in the empty card management control reference information table.

STOCKER	DURABLESPEC	QUANTITY	PRIORITY
				PFST01	8PCA	3	2
PFST01	8PCB	3	2
				PFST02	8PCB	4	1
PFST02	8PCA	3	1
				PFST03	8PCA	3	3

Specifically, the storer in the above table indicates the name of the storage area requiring an empty card; the DURABLESPEC represents the type of empty cards which can appear in the current memory area, the queue represents the number requirement of empty cards needed by each device, and the PRIORITY represents the PRIORITY of the type of empty cards corresponding to the current memory area in all memory areas.

Optionally, in the foregoing management and control method provided in the embodiment of the present invention, in order to ensure that the storage area with a lower priority has empty cards required by the storage area with a higher priority, several virtual devices may be established in the storage area, and various types of empty cards are registered on the virtual devices, so as to implement the minimum holding capacity of each type of empty card.

Optionally, in the management and control method provided in the embodiment of the present invention, the step S104 determines whether the number of empty cards in each storage area reaches the corresponding storage area level number management and control limit, as shown in fig. 2, specifically may be implemented in the following manner:

and determining whether the number of the empty cards in the storage area reaches the corresponding storage area level number control limit step by step according to the sequence of the priority of the storage areas from high to low. For example, as shown in fig. 2, step S1041 may be performed first to determine whether the number of empty cards in the storage area with the highest priority reaches the corresponding storage area level number management limit, step S1042 may be performed to determine whether the number of empty cards in the storage area with the next priority reaches the corresponding storage area level number management limit, and so on, and step S104n may be performed finally to determine whether the number of empty cards in the storage area with the lowest priority reaches the corresponding storage area level number management limit.

Specifically, a priority of transportation is formed by setting the priority in each storage area, the storage area with high priority is used for pulling the empty card in the storage area with low priority, and the empty card is pulled to a required place step by step one by one, so that the occupation of resources by long-distance transportation can be avoided, and the reaction speed and the reaction efficiency can be improved.

Optionally, in the foregoing management and control method provided in this embodiment of the present invention, when it is determined that the number of empty cards in the storage area does not reach the corresponding storage area level number management and control limit, step S105 obtains an empty card of a required type from a storage area with a low priority, as shown in fig. 3, and may specifically be implemented as follows:

when the number of the empty cards in the storage area of the level does not reach the control limit of the number of the corresponding storage area levels, judging whether the storage area with low priority has the empty cards of the type required by the storage area of the level step by step according to the sequence of the priority of the storage areas from high to low until the storage area of a certain level with low priority is judged to have the empty cards of the type required by the storage area of the level;

and carrying the empty card of the type required by the level storage area into the level storage area from the level storage area with low priority.

For example, as shown in fig. 3, taking the storage area with the highest priority as an example, after step S1041 is executed, when it is determined that the number of empty cards in the storage area with the highest priority does not reach the corresponding storage area level number control limit, step S1051 is executed to determine whether an empty card of the type required by the storage area with the highest priority is present in the storage area with the lower priority, if so, step S1051 'is executed to transfer the empty card of the type required by the storage area with the highest priority into the storage area with the highest priority, if not, step S1052 is executed to determine whether an empty card of the type required by the storage area with the highest priority is present in the storage area with the lower priority, and so on, until step S105n is executed to determine whether an empty card of the type required by the storage area with the highest priority is present in the storage area with the lowest priority, if so, step S105 n' is executed from the storage area with the lowest priority, and carrying the empty card of the type required by the storage area with the highest priority into the storage area with the highest priority, and if not, exiting the process.

Specifically, by setting the priorities in each storage area, a priority for carrying is formed in a production factory, when the storage area with the highest priority does not reach the control limit, the empty card in the storage area with the lowest priority difference is pulled to be carried to the storage area, the empty card is pulled to the required place step by step, the distance for carrying the empty card can be shortened as much as possible, and the reaction speed and the reaction efficiency are improved.

Optionally, in the foregoing management and control method provided in this embodiment of the present invention, when it is determined that the number of empty cards in the storage area does not reach the corresponding storage area level number management and control limit, in step S104, a required type of empty card is acquired from a storage area with a low priority, as shown in fig. 3, specifically, the following method may also be implemented:

after executing step S104n, when it is determined that the number of empty cards in the storage area with the lowest priority does not reach the corresponding storage area level number control limit, executing step S106 to determine whether the set area of the production plant has an empty card of the type required by the storage area with the lowest priority; if yes, go to step S107; if not, the process is exited;

s107, the empty card of the type required by the storage area with the lowest priority is conveyed to the storage area with the lowest priority from the set area of the production factory.

Specifically, for the storage area with the lowest priority, the empty cards stored in the set area of the production factory can be pulled, so that the distance for conveying the empty cards is shortened as much as possible, and the reaction speed and the reaction efficiency are improved.

Specifically, in the management and control method provided in the embodiment of the present invention, on one hand, empty cards in each storage area inside a production plant can be determined, and when a storage area with an incorrect location and a higher priority is required, a response is made in time to automatically adjust the distribution of the empty cards.

On the other hand, optionally, in the management and control method provided in the embodiment of the present invention, an empty card of the module factory may also be managed and controlled, as shown in fig. 4, specifically, the method may include the following steps:

s401, a production factory receives an empty card unloading Request (Unload Request) sent after the module factory finishes producing empty cards;

s402, determining whether the number of the empty cards of the type in the production plant reaches the plant level number control limit; the factory level quantity control limit is the accumulated sum of the storage level quantity control limits of the current storage areas; if yes, go to step S403; if not, go to step S404;

s403, storing the generated empty card in a module factory;

s404, the empty card generated in the module factory is conveyed to a set area of the production factory for storage.

Specifically, in the management and control method provided in the embodiment of the present invention, after the module factory completes production, an empty card unloading request is sent to the production factory; under the condition that the production factory meets basic conditions, logic of empty card management and control is triggered, information judgment is conducted on currently generated empty cards, whether the current type of empty cards reaches factory level quantity management and control limits or not is judged, if yes, the currently generated empty cards are left in the module factory, and if not, the generated empty cards are conveyed to the production factory so as to adjust distribution of the empty cards in the module factory.

Optionally, in the management and control method provided in the embodiment of the present invention, the step S404 transports the empty card generated in the module factory to a set area of a production factory for storage, and may be specifically implemented by:

firstly, judging the type of an empty card generated in a module factory;

and then, according to the judged type of the empty card, the empty card generated in the module factory is conveyed to a set area matched with the type of the empty card in the production factory for storage.

Specifically, for example, as shown in fig. 5, step S501 determines whether the type of the empty card generated in the module factory is I-type; if yes, executing step S502, transporting the empty card generated in the module factory to the production factory and storing in the I-type setting area; if not, step S503 is executed to transfer the empty card generated in the module factory to the type II setting area in the production factory for storage. For example, the type I card slot may be a PCA card slot and a PCB card slot, and the type II card slot may be a PCA card slot, a PCB card slot and a PCC card slot, which are specifically classified according to actual production, and are not limited herein.

Specifically, under the restriction of quantity management and control of carrying is not reached, the destinations of carrying are screened, the destinations are carried to different types of set areas according to different empty card types, the accuracy of carrying can be improved, situations such as secondary carrying and reverse logistics carrying are avoided, and the set areas generally arrive the fastest after being returned to a production factory from a module factory and belong to requisite storage areas.

Optionally, in the control method provided in the embodiment of the present invention, after the step S403 deposits the generated empty card in the module factory, as shown in fig. 6, the method may further include:

s601, every second set time interval; specifically, the method can be implemented by setting a Timer (Timer), and the second set time period of the specific setting can be set according to actual needs, which is not limited herein;

s602, determining whether an empty card is needed in a production factory, if so, executing a step S603, otherwise, executing a step S601;

and S603, conveying the empty card to a storage area which needs the empty card and has the highest priority.

Specifically, the empty card of depositing at module factory has an important role just in order to practice thrift the storage space of production factory, under the inconsistent condition of product structure, the condition that production factory only used single type draw-in groove can appear, because the quantity of draw-in groove is limited, how quick circulation just becomes the key consequently, if the empty card that will not use is deposited the module factory, can practice thrift a large amount of spaces for the production factory, makes the commodity circulation of production factory better smooth and easy.

To sum up, the above control method provided by the embodiment of the present invention mainly implements two functions: 1. and (4) judging the unloading of the empty cards after the production of the module factory is finished, judging whether the production factory needs the type of empty cards, and then carrying out corresponding operation. 2. The operation of the timer is carried out at regular time, the empty cards staying in the module factory and the production factory are judged, and the distribution of the empty cards is automatically adjusted in time in response to the condition that the positions are not right and the storage areas with higher priority have requirements.

In addition, the control method provided by the embodiment of the invention aims at the problems that the carrying of empty cards from the existing module factory to the production factory is too long and the space of the production factory is limited. There are two main directions of regulation, one for quantity and one for location. There are two aspects to quantity management and control, and one aspect is factory level quantity management and control: the specific required quantity of the production factory for various types of empty cards is calculated according to different product combinations, and on the other hand, the storage area quantity management and control is as follows: and calculating the specific requirement of the corresponding number of the empty cards according to the different process procedures in the storage area. There are two aspects to location management, one is factory level location management: automatically judging whether the total number of the empty cards in the production factory meets the requirements or not under different product combinations, and if not, pulling the empty cards in the module factory to return to the production factory; another aspect is storage area location management: the number of the empty cards in each storage area is changed continuously, and the required empty cards are automatically obtained from the storage area with lower priority according to the requirement. By the management and control method provided by the embodiment of the invention, empty card conveying management can be improved, and conveying efficiency and equipment utilization rate are improved.
