Abstract
The utility model provides an electronic tag reader-writer of an integrated Ethernet controller. The reader-writer is provided with an MCU controller which is respectively connected with an Ethernet protocol chip and a radio-frequency circuit, a power supply level conversion chip used for converting a 48V power supply of Ethernet into a 3.3V power supply; wherein an MCU control chip can be used for realizing TCP/IP protocol, and the Ethernet protocol chip is used for processing physical layer protocol of the Ethernet. The electronic tag reader-writer has the advantages that only one control chip can be used for realizing the control for an electronic tag read-write circuit and the Ethernet protocol, so that the hardware cost is saved, and the power supply can be obtained through the Ethernet.
Description
Technical field
The utility model relates to a kind of intelligent electronic label read write line, particularly a kind of high-frequency label read-write machine with ethernet controller.
Background technology
Thereby electronic label read/write is meant the device of the information in the label read write tag that activates by particular field strength.Because therefore the not stationarity that label is installed needs a lot of platform read write line equipment to work simultaneously.And Ethernet interface and network are modern factories and do the most general network in place, so utilize this ready-made network can make things convenient for installing and using of on-the-spot read write line.
Summary of the invention
The technical matters that the utility model solves is that a kind of electronic label read/write with Ethernet control will be provided, and the working power of read write line can be provided by ethernet network; Its scheme is: a MCU controller is set, is connected with radio circuit with the Ethernet protocol chip respectively, other establishes a power level conversion chip is the 3.3V power supply with the 48V power source conversion of Ethernet; Wherein, the MCU control chip is realized ICP/IP protocol, and the Ethernet protocol chip is handled the ethernet physical layer agreement.
The utility model utilizes a kind of control chip efficiently and Ethernet interface chip.The Ethernet interface chip is handled the physical layer protocol of Ethernet, and control chip is realized the ICP/IP protocol of network.Provide a stable ± 48V direct supply by special equipment for network simultaneously, all are articulated in the electronic label read/write of this network and can both power by Ethernet interface.
Superior effect of the present utility model is: only realize control of electronic label read-write circuit and Ethernet protocol with a control chip, with the economize on hardware cost, and can obtain power supply by Ethernet.
Description of drawings
Accompanying drawing 1 is a block scheme of the present utility model.
Specific implementation
Electronic label read/write of the present utility model is made of a control chip, Ethernet protocol chip, power conversion chip, electronic label read-write circuit.
See also shown in the accompanying drawing 1, a MCU controller 1 is set, be connected with radio circuit 3 with Ethernet protocol chip 2 respectively, other establishes a power level conversion chip 4 is the 3.3V power supply with the 48V power source conversion of Ethernet, is connected with Ethernet with interface 5; Wherein, MCU controller 1 is realized ICP/IP protocol, and Ethernet protocol chip 2 is handled the ethernet physical layer agreement.Each module routine of last figure is as follows:
Data on the network transmit by Ethernet interface 5, at first by power level conversion chip 4 with on the network ± the 48V voltage transitions becomes card reader working power voltage 3.3V, offers each operational module then.Ethernet protocol chip 2 is handled the communication transmitting data of ethernet physical layer, and MCU controller 1 realizes by parallel bus the agreement of ethernet link layer and communication layers is realized being ICP/IP protocol.MCU controller 1 also will be controlled the operation that radio circuit 3 is realized electronic tag simultaneously.
All the chip model is as follows:
| The chip model | Effect | Manufacturer |
| CP2200 | The Ethernet protocol chip | Silicon Labs |
| Si3400 | The power level conversion chip | Silicon Labs |
| C8051F340 | The MCU controller | Silicon Labs |
| FM1725 | The electronic tag radio frequency chip | Fudan University's microelectronics |
Wherein power level conversion chip 4 be responsible for on the Ethernet ± the 48V voltage transitions becomes the operating voltage of 3.3V on the circuit board, Ethernet protocol chip 2 will be handled the physical layer data message on the network, and control module (MCU) will be realized the agreement of link layer, network layer and session layer, realize the foundation of TCP/IP data channel.Control module also is responsible for handling the detection and the read-write capability of electronic tag simultaneously.Because adopted the control chip of basic unit's ethernet feature, integral body has promoted the performance of electronic label read/write.Saved the cost of external power supply and network layout, do not needed man-to-man connection computer work, can on a computer, carry out control operation unlimited many remote read write lines.
