The present invention is further described with reference to the accompanying drawings, and the following examples are only for clearly illustrating the technical solutions of the present invention, and should not be taken as limiting the scope of the present invention.
Example 1
As shown in fig. 1, a method for searching a dead tray in an elevated library according to an embodiment of the present invention includes:
and S1, acquiring a multi-dimensional form, wherein the multi-dimensional form comprises an elevated warehouse goods position table and a tray information table.
Firstly, a multidimensional form is established, wherein the multidimensional form comprises an elevated warehouse cargo space table and a tray information table, the elevated warehouse cargo space table is TWMS _ LOC, and the tray information table is TWMS _ PLT.
The tray information table includes the following fields: SLOC source region, PLTNUM container number, ITEMCMBAUTONUM material combination auto-number, STATUS STATUS, VPTNUM virtual container, CURROC current region, OBJECTYPE object type, PLTAUTOTYPE container auto-type, PLTTYPE container type, IFFULLPLT full disk, ITEMTYPE material category, PACKDATE group disk time, OLDMVINATE earliest move-in time, MVINDATE move-in time, DLOC target region, ENTERDATE entry time.
The current region of the CURROC can reflect the information of the goods position, and if the goods position has no information, the current region indicates that the tray is not checked.
The elevated warehouse goods position table comprises the following fields: OBJECTTYPE location type, IFDUMMYLOCO virtual area, LOCCMBNUM material identity, I _ PRIORITY move-in PRIORITY, STNTYPE station type, LOCNUM location number, SYSNODE system number, LOCDCSNUM control number, LOCDESC location description, ADDRESS ADDRESS, LOCSTATUS location status, O _ PRIORITY move-out PRIORITY, MVSTOCK1 area move policy, LABYNENUM attributed roadway, LOCSTORESTATUS area store status, PRNTUM parent location number.
The storage state of the LOCSTORESTATUS region comprises the following fields: MoveIn move in allocation, free idle, Load, MoveOut move out allocation.
Where the PRNTNUM parent location number contains an elevated library number and a lane number, such as: if the PRNTUM parent position number is L0463-00 y%, L0463 is an auxiliary material library, L046 x-001% is a first roadway, L0463-002% is a second roadway, and L0463-003% is a third roadway.
In the embodiment, the stagnant tray searching method is used for carrying out multi-dimensional identification by jointly inquiring the goods location table of the elevated warehouse and the tray information table through the inquiry behavior of the multi-table joint inquiry database.
In the database system, a user mainly interacts with the database management system through an SQL statement to complete operations such as information query, modification, deletion and the like, and the information state and the goods space state of the stock of the elevated library can be queried relatively quickly through the execution of the SQL statement.
S2, comparing the goods position state in the goods position table of the elevated warehouse with the goods position information in the tray information table to obtain the abnormal goods position which is judged to be abnormal, wherein the tray corresponding to the abnormal goods position is a dead tray.
As shown in fig. 2, the goods location table of the elevated warehouse is searched to determine the goods location state, then the father location number is screened, and then the screening location number is compared with the goods location information in the pallet information table, and the result is divided into four conditions:
(1) the goods position state is not free, and the tray information is available;
(2) the goods position state is not free, and the tray information is none;
(3) the goods position state is free, and the pallet information is available;
(4) the goods position state is free, and the pallet information is none;
the above cases (1) and (4) determine that the state is normal, and the cases (2) and (3) determine that the state is abnormal.
Detailed description will be given of (1) as "finding the cargo space not free, the cargo space with pallet data", detailed description will be given of (2) as "finding the cargo space not free, but the cargo space without pallet data", detailed description will be given of (3) as "finding the cargo space free, but the cargo space with pallet data", and detailed description will be given of (4) as "finding the cargo space free, but the cargo space without pallet data".
The specific query conditions of the goods position state and the goods position information are as follows:
(1) finding the goods position with tray data, wherein the goods position is not free;
select t.*, t.rowid from TWMS_LOC t
where T.LOCSTORESTATUS <> 'Free'
and T.PRNTNUM in ('L0463_001%', 'L0463_002%','L0463_003% ')
and T.LOCNUM in(select T.CURRLOC from TWMS_PLT T);
(2) finding the goods position which is not free but has no tray data;
select t.*, t.rowid from TWMS_LOC t
where T.LOCSTORESTATUS <> 'Free'
and T.PRNTNUM in ('L0463_001%', 'L0463_002%','L0463_003%')
and T.LOCNUM not in(select T.CURRLOC from TWMS_PLT T);
(3) finding the goods position with the tray data as free;
select t.*, t.rowid from TWMS_LOC t
where T.LOCSTORESTATUS = 'Free'
and T.PRNTNUM in('L0463_001%','L0463_002%', 'L0463_003%')
and T.LOCNUM in(select T.CURRLOC from TWMS_PLT T);
(4) finding the goods position which is free but has no tray data;
select t.*, t.rowid from TWMS_LOC t
where T.LOCSTORESTATUS = 'Free'
and T.PRNTNUM in('L0463_001%','L0463_002%', 'L0463_003%')
and T.LOCNUM not in(select T.CURRLOC from TWMS_PLT T);
and (2) finishing the execution of data sentences of (2) finding the goods position which is not free but has no tray data ", and inquiring the goods position of which the information is lost due to operation, system failure, equipment failure and the like.
And (3) finishing the data statement execution of finding the goods position with idle goods position and tray data, and inquiring the goods position with lost materials caused by operation, system fault, equipment fault and the like.
And (3) the dead tray can be searched only by correctly displaying the goods positions corresponding to the abnormal (2) and (3), and the tray corresponding to the abnormal goods position is the dead tray.
The searching method further comprises a step of tray checking, wherein an elevated Warehouse (WMS) generates a delivery task according to a delivery order, a system calls out corresponding auxiliary material cigarette real trays and reads and checks electronic tag information through RFID (electronic tag systems, 4 in the embodiment) configured on each roadway delivery platform, after the RFID reads the electronic tag information on the checking trays, if the checking is qualified, a delivery signal is sent out, the trays are automatically conveyed to the AGV delivery conveyor platform, and simultaneously the information is transmitted to an LED display screen of each AGV delivery conveyor platform, the trays containing auxiliary materials on the AGV delivery conveyor platform are removed, and the unloading of the auxiliary materials is completed at the moment; if the checking is unqualified, a warehouse returning signal is sent out, the tray is automatically conveyed back to the elevated warehouse, the tray is marked to be checked in the warehouse area, and the tray is called out of the elevated warehouse for manual checking and processing in the idle time period; the tray checking step ensures that the physical information in the trays of the whole elevated library is consistent with the information in the database.
The technical scheme of the invention can reduce the workload of searching the dull trays in the single elevated warehouse by 2 persons for four working days to 10 minutes/time, and the frequency of searching the dull trays can be adjusted from 2 times/year to 1 time/week to become a normalized work.
