Abstract
The utility model discloses a kind of anti-interference RFID reader devices, comprising: RFID card reader, RFID label tag, control unit and metallic shield.The RFID card reader is installed on the chassis of AGV vehicle, and the RFID label tag is installed on the parking stall of ground；Described control unit is installed on AGV car and connection RFID card reader；The metallic shield bottom opening including top surface and four sides；The RFID card reader is fixed in metallic shield.The utility model can shield the stability that external electromagnetic signal works to the interference of RFID card reader, guarantee system.
Description
Technical field
The utility model belongs to automated guided vehicle field technical field, relates in particular to a kind of anti-interference RFID reading
Card device.
Background technique
With advances in technology, AGV (Automated Guilded Vehicle) vehicle as it is a kind of have safeguard protection and
The carrier for transplanting function, because its supermatic characteristic, is widely used in mechanical stereo parking garage field.Application
Number for 201710744040.0 patent application in disclose in the prior art using RFID device realize AGV vehicle control system
System: RFID card reader is set by the way that RFID label tag is arranged on each ground station of magnetic stripe guide rail, while in AGV vehicle bottom.
When AGV is run to close to RFID label tag, RFID card reader detects the information in RFID label tag and is transferred to control unit,
The operation work of AGV vehicle is adjusted by control unit.But in practice it has been observed that being installed on the RFID on AGV car bottom plate
Card reader is easy to be led to RFID at work by extraneous electromagnetic interference, occur it is abnormal read error in data, crash,
The problems such as data link noise is larger.And then cause error rate BER higher, make system job insecurity.Therefore, how to open
A kind of novel anti-interference RFID reader device is issued, the above problem can be overcome, is that those skilled in the art need to study
Direction.
Utility model content
The purpose of the utility model is to provide a kind of anti-interference RFID reader devices, can shield outside electromagnetic interference, protect
Card system the operation is stable.
The technical scheme adopted is as follows:
A kind of anti-interference RFID reader device, comprising: RFID card reader, RFID label tag, control unit and metallic shield.
The RFID card reader is installed on the chassis of AGV vehicle, and the RFID label tag is installed on the parking stall of ground；Described control unit peace
And connection RFID card reader interior loaded on AGV；The metallic shield bottom opening including top surface and four sides；It is described
RFID card reader is fixed in metallic shield.
Preferably, in above-mentioned anti-interference RFID reader device: the metallic shield is fixed on by rivet or screw
On the bottom plate of AGV vehicle.
By using above-mentioned technical proposal: effectively raising the electromagnetic immunity energy of RFID after adding metallic shield
Power ensure that the stability of system work.
Compared with prior art, the utility model structure is simple, easily prepared.Outside electromagnetic interference can be shielded, guaranteed
System the operation is stable.
Detailed description of the invention
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
Fig. 1 is the functional block diagram of embodiment 1, and metallic shield is omitted in this figure；
Fig. 2 is the connection relationship diagram in embodiment 1.
Each appended drawing reference and component names corresponding relationship are as follows:
1, RFID card reader；2, RFID label tag；3, control unit；4, metallic shield.
Specific embodiment
In order to illustrate more clearly of the technical solution of the utility model, further retouched below in conjunction with each embodiment
It states.
As shown in Figs. 1-2 it is embodiment 1:
A kind of anti-interference RFID reader device, comprising: RFID card reader 1, RFID label tag 2, control unit 3 and metallic shield
Cover 4.The RFID label tag 2 is installed on the parking stall of ground；Described control unit 3 is installed on AGV car and connection RFID card reader
1；The metallic shield 4 is fixed on the bottom plate of AGV vehicle by rivet or screw.4 bottom opening of metallic shield, packet
Include top surface and four sides；The RFID card reader 1 is fixed in metallic shield 4.
In practice, the specification of shielding case is related with RFID card reader size, and specific requirement is each identity distance of shielding case from RFID
Reader surface 50mm, RFID card reader invagination such as shielding shroud rim 10mm.
The above, only specific embodiment of the utility model, but the protection scope of the utility model is not limited to
This, any those skilled in the art is in technical scope disclosed by the utility model, the variation that can readily occur in
Or replacement, it should be covered within the scope of the utility model.The protection scope of the utility model is with claims
Subject to protection scope.
