Description

A kind of RFID handheld devices
Technical field
The utility model is related to radio RF recognition technology fields, more particularly, to a kind of RFID handheld devices.
Background technology
Radio frequency identification (Radio Frequency Identification, RFID) is a kind of automatic identification and acquisition The technology of data carries out non-contact bidirectional data communication by radio frequency method and achievees the purpose that identify target, with existing For the development of information technology, RFID technique is because its is safe, storage information capacity is big, can be obtained the features such as untouchable identification Very extensive application;In recent years, it is hand-held to be widely used in bank in internet data acquisition industry for RFID handheld devices The fields such as the POS, logistic track scanning machine, the acquisition of common RFID handset datas and works as hand apart from short on the market at present When holding equipment sends order to multiple electronic tags simultaneously, it is easy to which there is a situation where multi-tags to collide, and causes information to read tired Difficulty, reading efficiency are relatively low.
Invention content
The utility model reads aiming at existing RFID handheld devices and is asked apart from the shorter and lower technology of reading efficiency It is longer with the higher RFID handheld devices of reading efficiency to provide a kind of readings distance for topic.
For this purpose, the utility model includes shell, RFID read-write module, communication module, radio-frequency antenna set on enclosure interior Plate and power module, communication module include bluetooth-communication unit and voltage conversion unit, and radio-frequency antenna plate is equipped with radio-frequency antenna, RFID read-write module is connect with communication module and radio-frequency antenna respectively, and power module is connect with communication module.
Preferably, RFID read-write module uses hyperfrequency SLR1200 modules.
Preferably, RFID read-write module is connect by serial line interface with communication module.
Preferably, radio-frequency antenna is 8dBi linear polarized antennas.
Preferably, RFID read-write module is connect by MMCX connectors with radio-frequency antenna.
The utility model is simple in structure, and the working frequency of RFID read-write module is 920~925MHz, for collecting and handling The RF tag signal that radio-frequency antenna receives, and signal is interpreted as to the ID data of identifiable 16 digit word format, RFID read-write module has high-performance multi-tag recognizer, can receive the signal of multiple RF tags simultaneously, and maximum is penetrated Frequency power output is up to 30dBm, and strong antijamming capability, reading efficiency is higher, and is penetrated with the use of 8dBi linear polarized antennas The reception of frequency signal reads distance up to 8m;By setting bluetooth-communication unit, the wireless communication of RFID handheld devices is realized, It is practical and convenient.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawings.
As shown in Figure 1, the utility model includes shell, RFID read-write module, communication module, radio frequency set on enclosure interior Antenna plate and power module, radio-frequency antenna plate be equipped with radio-frequency antenna, RFID read-write module respectively with communication module and radio frequency day Line connects, and power module is connect with communication module;
Radio-frequency antenna, for transmitting and receiving radiofrequency signal;
RFID read-write module, for radio-frequency antenna transmission radiofrequency signal, receiving the radiofrequency signal that radio-frequency antenna returns, and Radiofrequency signal is decoded as ID data, multiple label signals can be received simultaneously;
Communication module includes bluetooth-communication unit and voltage conversion unit, and bluetooth-communication unit is for receiving RFID read-write mould ID data is sent to receiving terminal by the ID data of block, and voltage conversion unit carries out voltage conversion, is RFID read-write mould Block is powered;
Power module provides power supply for communication module.
RFID read-write module uses hyperfrequency SLR1200 modules, supports that ISO18000-6C consensus standards, supply voltage are 5V, working frequency are 920~925MHz, can be adjusted according to the needs its output power, maximum radio frequency power output is reachable 30dBm;RFID read-write module has high-performance multi-tag recognizer, can receive the signal of multiple RF tags simultaneously, Inside can at most cache 299 radio frequency label informations;RFID read-write module is 50 Ω radio frequencies by MMCX connector matching impedances Antenna.
Radio-frequency antenna is 8dBi linear polarized antennas, and the MMCX that RFID read-write module is connected to by N/SMA antenna terminals connects Device is connect, the command reception or transmission radiofrequency signal being sent to according to RFID read-write module.
RFID read-write module also provides UART external communication interfaces, RFID read-write module by UART serial line interfaces with communicate Module connects, and decoded ID data is transmitted to communication module, and communication module is by its bluetooth-communication unit by label ID data are sent to receiving terminal, and receiving terminal can be mobile phone or computer with Bluetooth function.
Power module have the function of lay in electricity, capacity 1700mAH, export 3.7V voltages, power module with lead to To believe module connection, power supply is provided for communication module, 3.7V voltages are converted to 5V voltages by communication module by voltage conversion unit, Power supply is provided for RFID read-write module;Communication module also provides external USB interface, and it can be power module to be connect with external power supply Charging.
When RFID handheld devices work, RFID read-write module sends radiofrequency signal to read by radio-frequency antenna to RF tag Take label information, RF tag that label information is returned to RFID read-write module by radio-frequency antenna, RFID read-write module is to mark Label information is decoded processing, radiofrequency signal is converted to the ID data of identifiable 16 digit word format, then by it It is transferred to receiving terminal by bluetooth-communication unit, for users to use;By the way that the output power of RFID read-write module is adjusted to 30dBm, and by the direction of the longest direction alignment RF tag of radio-frequency antenna lobe, it can be achieved that the reading distance of 8m, reads effect Rate is higher.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this The range of implementation, therefore the displacement of its equivalent assemblies, or according to equivalent variations made by the utility model patent protection domain and change, It all should still belong to the scope that the utility model claims book is covered.
