Detailed description of the invention
Technical scheme is further illustrated below in conjunction with the accompanying drawings with case study on implementation.
A kind of based on RFID flat storehouse fork truck alignment system, it is characterised in that by RFID, RFID antenna, RFID
Read write line, RFID information processing equipment, location-server sequentially connect.
The present invention is by least one RFID by radiofrequency signal and rfid interrogator communication, and RFID antenna is passed through
Radio frequency feed line is connected with rfid interrogator, and rfid interrogator uses physics to electrically connect with RFID information processing equipment, RFID information
Processing equipment is connected with location-server by wireless network.
RFID of the present invention is arranged on above the goods yard needing location；
Described rfid interrogator, RFID antenna, RFID information processing equipment are arranged on fork truck, and rfid interrogator reads institute
State the data message of RFID label tag, and by described FRID label information transmission to described RFID information processing equipment；
The described FRID label information that described RFID information processing equipment reads according to described rfid interrogator, counts
According to process, and result is sent to described location-server by wireless network；
After described location-server receives the result of described RFID information processing equipment, according to predefined label
With the position that the corresponding relation of position judges current fork truck.
RFID of the present invention is ultrahigh-frequency passive electronic tag, and described RFID antenna is hyperfrequency circular polarisation
Antenna, the described split type read write line of rfid interrogator hyperfrequency.
Rfid interrogator of the present invention, the power supply of RFID information processing equipment are provided by forklift truck storage battery.
Rfid interrogator of the present invention and RFID information processing equipment use the connected mode of physical connection to include at least
One below: serial ports, network interface.
All RFID device in the present invention are hyperfrequency equipment, and rfid interrogator uses split type equipment, with RFID
Radio frequency feed line is used to connect between antenna.Rfid interrogator sends radiofrequency signal all the time, when through being pasted with RFID
Region time, automatically read RFID information.The power supply of rfid interrogator is provided by fork truck.
RFID in the present invention is ultrahigh-frequency passive electronic tag, is pasted onto the top, goods yard needing location.
Before pasting, need to decide whether to install isolating device additional according to installation environment.If being arranged on the material that dielectric constant is higher
Upper (such as metal), needs to install one layer of relatively low isolating device of dielectric constant between installed surface and RFID additional.?
Before stickup, need to perform hair fastener operation according to the predefined rule of alignment system, predefined positional information coding is write
In RFID label tag.
RFID antenna in the present invention is circular polarized antenna, is arranged on fork truck top, and between rfid interrogator, employing is penetrated
Frequently feeder line is attached.
