Abstract

The utility model discloses a wireless transceiver of digital-control machine, comprising a digital-control machine terminal and a computer terminal, wherein the digital-control machine terminal and the computer terminal both have a wireless transmitting-receiving module and a communication cable, wherein the digital-control machine terminal has a chip of FPGA and a configured chip of EPC2, the computer terminal has a chip of MAX232. The utility model constructs the radio communication on the base of the chip of FPGA between the digital-control machine and the computer, therefore, digital-control machine can be connected with various computers flexibly without arranging wires, and the digital-control machine can remove the connection after acquiring the processing program, to save the working space.

Description

The NC machine tool wireless transceiver

One, technical field:

The utility model relates to the equipment that a kind of numerically-controlled machine and computing machine communicate.

Two, background technology:

At present, the numerically-controlled machine owning amount of the many enterprises of China constantly increases, numerically-controlled machine of a great variety.In order to enhance productivity, to need numerically-controlled machine to be connected, and communicate and control with computing machine; Simultaneously, the network manufacturing has become the modern gordian technique of making, the network manufacturing at first requires numerically-controlled machine and computing machine are communicated, the numerically-controlled machine of considering present a lot of enterprises mounting arrangements finishes, arrange that separately communication line will bring inconvenience, and the reliability of circuit is difficult to also guarantee.

Three, technical scheme:

The purpose of this utility model is to provide a kind of NC machine tool wireless transceiver that does not need communication line just can solve communication between numerically-controlled machine and the computing machine.

The utility model adopts following technical scheme: a kind of NC machine tool wireless transceiver, include numerically-controlled machine end, computer terminal, numerically-controlled machine end, computer terminal all have a radio receiving transmitting module and a telecommunication cable, the numerically-controlled machine end has a fpga chip and configuring chip EPC2 chip thereof, and computer terminal has a MAX232 chip.

The utility model is by making up the radio communication based on fpga chip between numerically-controlled machine and computing machine, need not connect up and just can make numerically-controlled machine establish a communications link with all kinds of computing machines neatly, and after numerically-controlled machine has obtained job sequence from computing machine, computing machine can be removed voluntarily, has saved work space.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a circuit diagram of the present utility model.

Five, embodiment:

The utility model is described in further detail with embodiment with reference to the accompanying drawings below:

From Fig. 1, Fig. 2 as can be known, the utility model contains IC1-IC5 totally five integration modules, be welded on the circuitron, include the numerically-controlled machine end, computer terminal, the numerically-controlled machine end links to each other with numerically-controlled machine by standard RS-232 telecommunication cable T1, disposes fpga chip IC1 automatically by EPC2 chip IC 2 when powering at every turn, carry out storage, displacement and the communication format conversion of data in fpga chip inside, send or receive data by radio receiving transmitting module IC3 and computer terminal; Computer terminal links to each other by the serial port of standard RS-232 telecommunication cable T2 and computing machine, job sequence, control information etc. are sent through standard RS-232 telecommunication cable T2 by the serial port of computing machine, carry out the RS-232 data-switching through MAX232 chip IC 5, send or receive data by radio receiving transmitting module IC4 and numerically-controlled machine end, above-mentioned radio receiving transmitting module adopts PTR2000, and communication frequency is 433.92MHz/434.33MHz, the FSK modulation, the PLL frequency stabilization, traffic rate 19.2Kbit/s.

Fpga chip belongs to reconfigurable chip, and its procedure stores is in the EPC2 of circuit, therefore, according to concrete use occasion, can change EPC2, relevant communication format and agreement can be stored among the EPC2 like this, different occasions are changed EPC2 get final product, perhaps EPC2 is reshuffled and also can; Various protocols can certainly be stored among the EPC2, the peripheral hardware related circuit switches, and can accomplish the configuration communication of a computing machine to many numerically-controlled machines.
