Abstract
The invention provides a warehouse management apparatus applying surface acoustic wave labels, and belongs to the fields of electronics, sensors, communication and the like. The surface acoustic wave labels can read and write longer distances compared with conventional RFID labels, and need not to be powered by cells. The surface acoustic wave labels are stuck onto articles in a warehouse, and then the articles are placed in a storage area in the warehouse and can be tracked and located by a surface acoustic wave read-write device in the warehouse. A warehouse management system defines names, functions, parameter specifications and the storage life of the articles, and thus the articles are managed quickly and accurately.
Description
Technical field
Belong to the fields such as electronics, sensor, communication, relate to use sound surface label sensor, sound
Surface wave information reading and the information processing technology, be applied to warehouse management system.
Background technology
Conventional warehousing system, mainly by artificial cognition article, is followed the tracks of highly difficult for article in the position in warehouse,
Traditional RFID label tag reading/writing distance is near, and application is not very extensive, even if there being some simple application, cost is also
The highest, use the warehousing management device of passive sonic surface wave label technique can solve this problem well.
SAW ID-tag sensor is made up of sensor antenna, interdigital transducer and coded reflective district, sensing
Device antenna receives and is sent, by the reader within 15 meters, the access electromagnetic pulse signal of coming, and passes through interdigital transducer
It is converted into surface acoustic wave, after running into reflection bar, forms echo, different sound tables can be distinguished by resolving echo
Face ripple label.
Summary of the invention
It is an object of the invention to provide a kind of based on SAW ID-tag sensor, wireless data communication technology
WMS, SAW ID-tag can be more farther than traditional RFID label tag read-write, it is not necessary to
Battery is powered, the memory area that the article in warehouse are placed in warehouse after sticking SAW ID-tag, can be by storehouse
Read-write equipment track and localization in storehouse, warehouse management system defines Item Title, function, parameter specification, guarantor
Deposit the time limit, thus fast and accurately article are managed.
Hardware of the present invention, by the SAW ID-tag stored in a warehouse on article, installs the SAW reader in warehouse
And antenna, surface acoustic wave signal processing circuit, wireless messages transmitter/receiver circuit, integrated information processes circuit
Composition.
Technical scheme:
A kind of storehouse management device applying SAW ID-tag to realize, comprises: be placed on by storage article
Surface acoustic wave mark module, the surface acoustic wave read module being arranged in warehouse, surface acoustic wave signal processing
Module and wireless messages sending module, be arranged on the wireless messages receiver module of storehouse management room, signal processing
Module, the data output end of surface acoustic wave mark module connects the data input pin of surface acoustic wave read module,
The data output end of surface acoustic wave read module connects the data input pin of surface acoustic wave signal processing module, sound
The data output end of surface wave signal processing module connects the data input pin of wireless messages sending module, wireless
The data output end of information sending module connects the data input pin of wireless messages receiver module, and wireless messages connects
The data output end receiving module connects the data input pin of signal processing module.
The present invention has the advantage that:
1. can accurately follow the tracks of Item Title, function, parameter specification, fast and accurately article are managed.
Accompanying drawing explanation
Fig. 1 is the block diagram of the present invention.
Detailed description of the invention
As it is shown in figure 1, the data output end of surface acoustic wave mark module connects the number of surface acoustic wave read module
According to input, the data output end of surface acoustic wave read module connects the data of surface acoustic wave signal processing module
Input, the data that the data output end of surface acoustic wave signal processing module connects wireless messages sending module are defeated
Entering end, the data output end of wireless messages sending module connects the data input pin of wireless messages receiver module,
The data output end of wireless messages receiver module connects the data input pin of signal processing module.
Described surface acoustic wave mark module, comprises SAW ID-tag sensor, unique mark storage article.
Within the detection range of described surface acoustic wave read module is 15 meters, by arranging the sound table of different azimuth
Face ripple read module, then by signal to have that it's too late strong and weak, by surface acoustic wave signal processing module
Identify the apparent azimuth of article.
Described wireless messages sending module, is made up of high frequency radio emitter and antenna.
Described wireless messages receiver module, is made up of high frequency radio receptor and antenna.
Described signal processing module, is made up of digital processing circuit or embedded microprocessor, the thing to management
Product make a look up tracking Item Information.
Above one embodiment of the present of invention is described in detail, but described content has been only the present invention relatively
Good embodiment, it is impossible to be considered the practical range for limiting the present invention.All made according to the present patent application scope
Impartial change and improvement etc., within all should still belonging to the patent covering scope of the present invention.
