Summary of the invention

Problem for existing ultrahigh frequency electronic tag read-write system existence, the purpose of this invention is to provide a kind of ultrahigh frequency electronic tag read-write system based on panel computer, this system is take the smart machine of current state-of-the-art technology---and panel computer is the basis of operation read-write ultrahigh frequency electronic tag software.For achieving the above object, the present invention takes following technical scheme:

A kind of ultrahigh frequency electronic tag read-write system based on panel computer comprises panel computer, ultrahigh frequency electronic tag module for reading and writing, antenna, interface module and power module.Be provided with read-write ultrahigh frequency electronic tag software in the described panel computer; Described ultrahigh frequency electronic tag module for reading and writing and antenna form super high frequency electronic label read/write (seeing Fig. 3); Described interface module managing on the one hand be connected with panel computer with lower interface: WiFi interface, Ethernet interface, blue tooth interface, USB interface and UART mouth; Also be connected with the ultrahigh frequency electronic tag module for reading and writing on the other hand, and super high frequency electronic label read/write is undertaken (seeing Fig. 2) alternately by the some interfaces in the interface module and panel computer.

Described power module provides on the one hand to the power supply of ultrahigh frequency electronic tag module for reading and writing and the charge function of battery in the present invention, also can give on the other hand panel computer (1) power supply.Simultaneously, this system electronic intelligence equipment that panel computer can also be replaced by other moves read-write ultrahigh frequency electronic tag software.

The present invention has following apparent outstanding substantive distinguishing features and technical progress compared with prior art:

Operation interface of the present invention is directly perceived, information shows numerous; Touch-screen type is easy to operate simple.This system intelligent electronic device that panel computer can also be replaced by other moves read-write ultrahigh frequency electronic tag software simultaneously.

Embodiment

Specify the present invention below in conjunction with preferred embodiment:

Embodiment one:

As shown in Figure 1, the present embodiment comprises panel computer (1), ultrahigh frequency electronic tag module for reading and writing (2), multi-layer PCB antenna (3), interface module (4) and power management module (5) based on the ultrahigh frequency electronic tag read-write system of panel computer.Panel computer (1) links to each other with power module (5) and interface module (4); Interface module (4) connects panel computer (1), power module (5) and super high frequency electronic label read/write module (2); Super high frequency electronic label read/write module (2) connects antenna (3); Panel computer (1) function is the mutual demonstration of reading and writing device system; Power module (5) provides the power supply of whole ultrahigh frequency electronic tag read-write system; Interface module (4) then is the interface that connects panel computer (1), power module (5) and ultrahigh frequency electronic tag module for reading and writing (2); Ultrahigh frequency electronic tag module for reading and writing (2) then is that ultrahigh frequency electronic tag is read and write.

Embodiment two:

The present embodiment and embodiment one are basic identical, and special feature is as follows:

As shown in Figure 4, the core in the interface module is the ARM nuclear chip (45) of integrated USB, a UART and Ethernet in this embodiment.WiFi and blue tooth interface then are WiFi and the bluetooth modules (41) that adopts finished product, and this module is connected by UART mouth, I2C and GPIO with master control ARM unit (45).The data communication device that ultrahigh frequency electronic tag module for reading and writing (2) sends is crossed the UART interface and is sent to master control ARM unit (45), and this data communication device is then crossed a kind of the sending on the panel computer (1) in following several mode: WiFi (41), bluetooth (41), USB (42), UART (44) and the Ethernet (43) in master control ARM unit (45).The data that write ultrahigh frequency electronic tag module for reading and writing (2) for panel computer are then by the following interface mode of panel computer: a kind of the sending in the interface module (4) in USB, WiFi, Ethernet, the bluetooth, interface module is then crossed this data communication device UART and is sent in the ultrahigh frequency electronic tag module (2), and ultrahigh frequency electronic tag module for reading and writing (2) then writes data in the ultrahigh frequency electronic tag like this.Instruction for panel computer control ultrahigh frequency electronic tag module for reading and writing (2) then is by the following interface mode in the panel computer (1): USB, WiFi, Ethernet, a kind of of bluetooth send in the interface module (4), and interface module (4) is then come UHF electronic module for reading and writing (2) is controlled by GPIO.
