Abstract
The invention discloses a multi-antenna time-sharing reading device of an RFID (radio frequency identification) module, which comprises an RFID card reader module, a plurality of antennas and a plurality of micro switches. The RFID card reader module is connected with a plurality of antennas in parallel, each antenna is installed in a small storage cell of the intelligent storage cabinet, a microswitch is installed in a cabinet door of the small storage cell, and contacts of the microswitch are connected in series in an antenna loop of the small storage cell. When the cabinet doors of all the small storage cases are closed, the contacts of all the micro switches are in a disconnected state, and all the antennas are disconnected with the RFID card reader module. When the cabinet door of a certain small storage cell is selectively opened through the main control circuit of the intelligent storage cabinet, the normally closed contact of the micro switch in the small storage cell is connected, and the antenna of the small storage cell is communicated with the RFID card reader module. At the moment, the taking and returning operations of the instruments or medicines in the cells can be identified, and the identification information is uploaded to a main control circuit of the intelligent storage cabinet for recording and processing.
Description
Technical field
Dress is read in timesharing the present invention relates to the multiple antenna of RFID module connection of a kind of RFID reader, especially
Put.
Background technology
RFID REIDs are widely used in the every aspect for producing, living.The RFID radio frequency identifications of a set of discussion-of-politics
Device is made up of RFID card reader module, antenna and the identified part of RFID label tag three, and wherein RFID card reader module is core
The heart is also the part of most expensive.In the minitype precious instrument or medicine intelligence storage cabinet of a kind of exploitation of teaching-oriented R＆D institution
In, each cupboard has 20 small lattice of storing, each storing small lattice storage one instrument or a kind of medicine, above instrument or medicine holds
RFID label tag is posted above device, the small lattice of each storing are required for possessing the RFID label tag pasted above identification instrument or drug container
Function, taking and return the information such as time so as to automatic discrimination and register instrument or medicine.According to traditional scheme, each
The small lattice of storing need to install the RFID rfid devices of complete set.This causes that the cost of cupboard is very high, and 20 RFID
Rfid device read label information collect focus on be also required to complexity wired or wireless communication device.At present,
There are many researchs on a RFID card reader module management multiple antenna to report, its cardinal principle is multiple antennas work simultaneously
Make, main purpose is to improve recognition accuracy, increase identification coverage or multi-tag while recognizing.Patent ZL
201310278913.5 multiple antennas for being proposed are also to realize that multiple antennas work simultaneously using programme controlled polling mode.These
Method, is not all suitable for intelligent storage cabinet.
The content of the invention
The present invention proposes a kind of RFID multiple antennas timesharing reading device, can realize a RFID card reader module management
Multiple antennas, are mainly used in the intelligent storage cabinet of minitype precious instrument or medicine as the locker of similar supermarket.
The present invention realizes that the technical scheme that the timesharing of RFID multiple antennas is read is：In a minitype precious instrument or medicine intelligence
In the governor circuit of storage cabinet, a RFID card reader module is connected with.The antenna connection terminal of RFID card reader module is while simultaneously
The multiple antennas of connection, each antenna is arranged in the small lattice of storing of intelligent storage cabinet, is installed in the cabinet door of the small lattice of each storing
One microswitch, the normally-closed contact of microswitch is connected in the antenna loop of the small lattice of this storing.In the small lattice of all storings
In the state of cabinet door is all closed, the normally-closed contact of all microswitches all in off-state, all antennas and RFID card reader
The connection of module all disconnects.When the governor circuit by intelligent storage cabinet is by authentication and selects to open the small lattice of certain storing
During cabinet door, the normally-closed contact of microswitch is connected in the small lattice, and the antenna of the small lattice of the storing is connected with RFID card reader module.By
It is not very high in the frequency for taking and returning operation of instrument or medicine, the governor circuit of intelligent storage cabinet limits each moment most
A cabinet door for the small lattice of storing can only be opened more, so for RFID card reader module, although multiple antennas in parallel, but
It is that an antenna at most only opening cabinet door each moment is to turn on, now just can be to instrument in the small lattice or medicine
Take and return operation to be identified, and the governor circuit that identification information is uploaded to intelligent storage cabinet is recorded and processed.
The beneficial effects of the invention are as follows an intelligent storage cabinet need to only be equipped with a RFID card reader module, it is possible to manage
The multiple antennas of reason, realize reading the timesharing of instrument or medicine label in the small lattice of multiple storings, not only reduce whole intelligence storage
The cost of cabinet is hidden, and the information read to multiple antennas can be directly transmitted to master control electricity all in same card reader module
Road, without collecting, simplifies circuit.

Specific embodiment
In the governor circuit [7] of a minitype precious instrument or medicine intelligence storage cabinet [5], it is connected with a RFID and reads
Card device module [1]（RPD-MK-V1 types）.The antenna connection terminal [2] of RFID card reader module [1] while 20 antennas [4] in parallel,
1 microswitch [3] of series connection in the loop of each antenna [4]（KW8_OZ types）Normally-closed contact.Each antenna [4] and fine motion are opened
Pass [3] is in the small lattice of storing.In the state of the cabinet door [6] of the small lattice of all storings is all closed, all microswitches
[3] normally-closed contact all disconnects all in off-state, all antennas [4] with the connection of RFID card reader module [1].When passing through
The governor circuit [7] of intelligent storage cabinet by authentication and select open the small lattice of certain storing cabinet door [6] when, the small lattice of the storing
The normally-closed contact of interior microswitch [3] is connected, and the antenna [4] of the small lattice of the storing is connected with RFID card reader module [1].Due to instrument
The frequency for taking and returning operation of device or medicine is not very high, and the governor circuit [7] of intelligent storage cabinet limits each moment most
A cabinet door for the small lattice of storing can only be opened more, so for RFID card reader module [1], although multiple antennas in parallel
[4], but each moment antenna [4] at most only opening cabinet door is to turn on, now just can be to instrument in the small lattice
Taking and returning operation for device or medicine is identified, and the governor circuit [7] that identification information is uploaded to intelligent storage cabinet is entered
Row record and treatment.
The model of RFID card reader module [1] and microswitch [3] described in above-mentioned implementation method, can there is various differences
Model can select or replace on an equal basis.20 antennas [4] in parallel described in above-mentioned implementation method, it is also non-limiting, can be it
