Technical field
The invention belongs to a kind of adaptive stock of BOM materials in automatic detection field, more particularly to material logistics garden is pre- Alarm device.
Background technology
Stock is the major issue that Product processing enterprise, retailer, public good storage mechanism etc. face specifically how It is even more the focus as this problem to determine rational inventory amount.Quantity in stock can excessively cause the cost burden of enterprise or mechanism, and Quantity in stock is crossed and can not ensure meet consumer demand at least, thus rationally, the quantity in stock of safety can not only help all departments Control cost, at the same can also be sufficient guarantee consumer demand.Typically assessed at present by expert, model prediction or both knot The mode of conjunction carries out quantity in stock control, and expert's Evaluation Method is because subjective sex chromosome mosaicism being present and less use, model prediction method by In parameter is excessive or other problemses and seem that excessively complexity is limited by practical application, emergency rating is divided simultaneously because lacking Class and the using effect that have impact on prior art.
The content of the invention
To solve the above problems, the present invention provides a kind of adaptive stock's prior-warning device of BOM materials in material logistics garden, Can be by carrying out classification alert process to inventory status.
To reach above-mentioned purpose, adaptive stock's prior-warning device of BOM materials includes in material logistics garden of the invention：
Data input module, from radio transmitting and receiving chip JF24C, in real time record BOM materials warehousing quantity and outbound number Amount；
Data processing module, from microprocessor AT89C2051, for being screened, in advance to the data of data input module Processing, preservation and analogue simulation, and the data message to obtain data input module transmission is carried out as the beginning to these data messages Processing and emulation, give simulation results information transmission to stock's warning module；
Stock's warning module, from the single-chip microcomputer of MCS51 series, quantity in stock state in given period in future is carried out pre- Survey, and two-stage early warning is made respectively for normal type, Exception Type, when quantity in stock is in ± 0.4 times of normal stock, Think to belong to normal type, when quantity in stock exceedes ± 0.4 times of normal stock, it is believed that belong to Exception Type；
For normal type, early warning operation is not made, for Exception Type, it is believed that when quantity in stock be in normal stock ± At 0.4~± 0.8 times, one-level early warning is sent；When quantity in stock exceedes ± 0.8 times of normal stock, two level early warning is sent.
Further, the output end connection radio transmitting and receiving chip JF24C of AT89C2051 input, AT89C2051 XTAL1 and XTAL2 pins between connect crystal oscillator XI, AT89C2051 RST pins electricity connect by resistance R1 and key switch SI Source, AT89C2051 P3.7 pin are grounded by key switch S3, and AT89C2051 P1.0 pin are grounded by key switch S2, and Include FIFO.
The Early-warning Model s (t, n) of adaptive stock's prior-warning device is：
Wherein t is the entry time of BOM materials in material logistics garden；When n is the outbound of BOM materials in material logistics garden Between；krFor inventory change coefficient；RnFor the quantity in stock of different BOM materials；λ is the shelf-life of BOM materials in material logistics garden；g (t, n) is the alarm index of BOM materials in regulation material logistics garden.
The beneficial effects of the present invention are：
The present invention carries out real-time analog simulation to quantity in stock, and stock's early warning type is adaptively adjusted according to simulation result.
The present invention can be applied in Baosteel-Haier's material logistics garden by being emulated to automated response module, sent out Go out different early warning types.
Brief description of the drawings
