Abstract
The utility model discloses a handheld RFID (Radio Frequency Identification) card reader having Wi-Fi (Wireless Fidelity). The handheld RFID card reader includes a central controller CPU, an RFID read-write module, an RFID antenna, an OLED display, a keyboard and a Wi-Fi communication module. The central controller CUP connects with the RFID read-write module, the Wi-Fi communication module, the OLED display and the keyboard respectively. The RFID read-write module connects with the RFID antenna. The handheld RFID card reader can collect information of RFID labels in a region covered by Wi-Fi signals, and couples with an application terminal through the Wi-Fi communication module and transmits information data to an upper computer through internet directly without any cost. And the communication quality is stable and the transmission speed is high.
Description
Technical field
The utility model relates to reading and writing data and wireless communication technology field, particularly a kind of handhold RFID card reader with the Wi-Fi function.
Background technology
2.4GHz wireless communication technique is a kind of short range wireless transmission technology, has advantages such as bandwidth height, transmitted in both directions, strong interference immunity, long transmission distance, little power consumption.Main handhold RFID card reader (or claiming RFID handheld terminal) is all used the wireless technology of 2.4GHz frequency range on the market now.The communication scheme that is applied to the handhold RFID card reader at present mainly contains two types: the one, and adopt the GPRS module as main transport module, the 2nd, adopt bluetooth module as main transport module, there is following significant disadvantages in these two kinds of schemes:
The GPRS module is as the main means of long-distance transmissions; Have advantages such as long transmission distance, communication quality height and; But the problem that a key is arranged is in the process of using, can continue the generation expense, in some logistics or storage enterprise, will raise the cost virtually.And the transfer rate of GPRS is low, is merely 144Kbp/s like the transfer rate of GPRS Class 10, and high rate are but providing simple service.
Bluetooth module is a kind of short-distance transmission module, and communication distance is shorter, can't support the data transmission of long distance, and usable range is restricted.And the communication speed of bluetooth neither be very high, in the epoch of current this data explosion, the development that has been out of step with the times.The software and hardware platform of main flow does not mostly provide the support to bluetooth at present, and this makes the application cost of bluetooth raise, and popularizes difficulty and increases.
Therefore, the developer of handhold RFID card reader and user press for a kind of new communication scheme and substitute original old scheme, to improve use experience, reduce use cost.
The utility model content
Adopt GPRS module or bluetooth module as the existing above-mentioned drawback of transport module to existing handhold RFID card reader; The applicant improves through research; A kind of handhold RFID card reader with Wi-Fi is provided, adopts RFID Card Reader technology, adopt 2.4GHz super low-power consumption Wi-Fi module as wireless transport module; Not only transfer rate is fast, and need not any expense.
The technical scheme of the utility model is following:
A kind of handhold RFID card reader with Wi-Fi comprises central controller CPU, RFID module for reading and writing, RFID antenna, OLED display, keyboard and Wi-Fi communication module; Said central controller CPU is connected with RFID module for reading and writing, Wi-Fi communication module, OLED display and keyboard respectively; Said RFID module for reading and writing is connected with the RFID antenna.
Its further technical scheme is: the model of said Wi-Fi communication module is GS101X.
The useful technique effect of the utility model is:
One, the utility model can be gathered the information of rfid card sheet (or label) in Wi-Fi signal region covered is arranged, and directly docks with application end through the Wi-Fi communication module, directly is transferred to host computer to information data through the Internet.Need not any expense, and communication quality is stable, transfer rate is fast.
Two, the utility model has adopted super low-power consumption Wi-Fi communication module-GS101X, and the GS101X module adopts park mode idle the time, and power consumption consumption is very low, is merely several microamperes, can prolong battery working time greatly.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
As shown in Figure 1, the utility model is made up of central controller CPU 1, RFID module for reading and writing 2, RFID antenna 3, OLED display 4, keyboard 5 and Wi-Fi communication module 6.Wherein central controller CPU's 1 is the center of information processing and control, and it is connected with RFID module for reading and writing 2, Wi-Fi communication module 6, OLED display 4 and keyboard 5 respectively.
Radio frequency discrimination RFID (Radio Frequency IDentification) technology is a kind of automatic identification technology of realizing based on radio frequency recognition principle; It is crossed radio signals identification specific objective and reads and writes related data, is made up of module for reading and writing, antenna and electronic tag three parts.In the utility model, RFID module for reading and writing 2 and RFID antenna 3 have been formed the radiofrequency signal collection terminal of the utility model jointly, connect with wired mode between the two.RFID module for reading and writing 2 is to read or read/write device, and RFID module for reading and writing 2 carries out radio communication through RFID antenna 3 and various RFID electronic cards or label, then the information that reads is sent into central controller CPU 1 analysis and processing.
OLED display 4 and keyboard 5 have been formed the control end of the utility model jointly.Central controller CPU 1 puts the electronic tag data that reads and be presented in order on the OLED display 4, presents to the user, the user through keyboard 5 realize data inquiry, modification, function such as add up, upload.
Wi-Fi communication module 6 is the ties of linking up between the utility model and its application end (like host computer PC).Wi-Fi full name Wireless Fidelity claims the 802.11b standard again, is the industrial standard of a wireless communication of IEEE definition.Transmission speed can reach 11Mbps, and coverage is also very long, with existing various 802.11 DSSS hardware compatibilities.Present most school, hotel, coffee shop, water bar, airport all have wireless network to cover.For example can select GS101X type Wi-Fi communication module for use, GS101X adopts park mode idle the time, and power consumption consumption is very low, is merely several microamperes, can prolong battery working time greatly.
Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of the basic design that does not break away from the utility model, all should think to be included within the protection domain of the utility model.
