[description of drawings]
Accompanying drawing 1 is the structured flowchart of an embodiment of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
As shown in Figure 1, a kind of UHF Portable rfid interrogator, comprise radio-frequency module, logic control element module and antenna, described radio-frequency module comprises radio-frequency signal generator, radiofrequency launcher, radio frequency receiver and voltage regulator circuit, described logic control element comprises that MCU microprocessor, application interface drive, storage unit, it is characterized in that, also comprise wireless communication transmission system, power-supply system, described wireless communication transmission system is connected with logic control element, and described power-supply system is connected with radio-frequency module.Described wireless communication transmission optimum system choosing is a bluetooth communication equipment.Described power-supply system comprises rechargeable lithium ion batteries and charger for lithium ion battery.Described wireless communication transmission system drives with application interface in the logic control element and is connected.Described rechargeable lithium ion batteries is connected with voltage regulator circuit in the radio-frequency module.
Principle of work of the present utility model and process are as described below:
Radio-frequency module produces the ultrahigh frequency emitted energy, and the signal of emission is modulated, and the work of active electron label transfers data to electronic tag in effective distance of reaction, receives and modulate the radiofrequency signal from electronic tag simultaneously; The application interface of logic control element under the control of MCU microprocessor drives with wireless communication transmission system and host computer management software and carries out communication, and execution drives the instruction of sending from application interface, control the read write line and the communication process of electronic tag, the encoding and decoding of signal, and the identity of read write line and label is verified; Antenna is a kind ofly the electromagnetic wave that receives can be converted to current signal, or converts current signal to device that electromagnetic wave is launched.
Bluetooth communication equipment is a kind of based in the 2.4GHz of global general-use ISM (i.e. industry, science, medical science) frequency range, and the data rate of bluetooth is 1Mb/s.In 10 meters scopes can with wireless communication data transmission such as any PDA with bluetooth communication function, PC, notebook computer.The utility model has been expanded the connecting mode with other-end, changed to the cable connection mode between the terminal computer, thus flexible more and portable mobile reading tag information.
The utility model adopt 18VDC the 3.0Ah lithium ion battery, and adjust voltage through voltage regulator circuit and satisfy the required voltage power consumption of each system.The battery-powered mode of lithium-ion electric has made things convenient for especially at the environment that does not have mains-supplied to be used, the charger of commercial power interface is equipped with, can reuse the lithium ion cell charging of no electric weight easily, work long hours under the environment of civil power not having thereby greatly facilitate the utility model.
Though the utility model is described with reference to the above embodiments; but those of ordinary skill in the art can recognize very clearly that fully above embodiment is used to illustrate the utility model; wherein can make variations and modifications and not break away from the utility model in a broad sense; so be not that conduct is to qualification of the present utility model; as long as in connotation scope of the present utility model, all will fall within the protection domain that the utility model requires variation, the distortion of above-described embodiment.
