Description

USB probe controller

Technical field

The present invention relates to a kind of USB probe controller.

Background technology

In October, 1999, France SATIMO company trial-produceed a kind of multi-probe Antenna testing system, this multi-probe test successfully System is different from traditional test system, the Multi probe technology that it is started, and brings to electromagnetic arts and more rapid tests more accurately Solution and test result, be a significant innovation of near-field test technology, is the great revolution of antenna measurement technology.Nowadays Multi probe Antenna testing system has become the standard solution of wireless device test.The test speed that SATIMO is unmatched, meaning Taste investment repayment faster.Within 2006, test frequency range is extended to 70MHz to 18GHz by SATIMO Multi probe test system, from And it is wireless to make Multi probe technology be widely used in, automatization, national defence, the every field such as aviation.

The multiple probe controller in RF (radio frequency) and control unit, traditional many spies can be applied in Multi probe Antenna testing system Head controller is the most intelligent, controls use loaded down with trivial details, and without standby radio frequency interface when being out of order, work is easily interrupted.

Summary of the invention

Present invention solves the technical problem that and be for above-mentioned deficiency, it is provided that a kind of USB probe controller, the present invention realizes multiple Probe and radio frequency interface are controlled, the present invention in connection, it is possible on computers by simple and clear desktop application program Directly control rotation and the break-make of radio frequency interface of probe in test system, thus realize easy control.

Technical scheme is as described below: a kind of USB probe controller, it is characterised in that include usb data interface, list Sheet machine, field programmable gate array FPGA, data storage, level shifting circuit, interface circuit and peripheral power supply circuits, described Single-chip microcomputer connects field programmable gate array FPGA and usb data interface respectively, and described field programmable gate array FPGA passes through level conversion Circuit is connected with interface circuit, and described data storage is connected with described field programmable gate array FPGA, and described interface circuit is respectively Linking probe controller, radio-frequency switch circuit and electronic switching circuit, described usb data interface outer computer control signal And it being sent to described single-chip microcomputer, described single-chip microcomputer is processed to be converted into the level that field programmable gate array FPGA can directly read again Signal, described field programmable gate array FPGA by control signal input interface circuit respectively or turns through level after receiving signal on request Change circuit and be input to interface circuit, thus realize the break-make to radio-frequency switch circuit and the control of probe.

Further, described interface circuit includes DB15 interface circuit and DB26 interface circuit, described field programmable gate array Control signal is separately input in the DB15 serial ports specified after receiving signal by FPGA on request, is controlled this serial ports, thus Control the break-make of the radio-frequency switch circuit being connected with this interface circuit, DB26 is exported four to low and high level to each electrical switch simultaneously The RS232 serial ports being controlled being sent on panel with one group of control signal is controlled, it is achieved thereby that the control to probe.

Further, what described data storage was selected is flash chip.

Have the beneficial effects that according to the above-mentioned present invention: realize multiple probes and radio frequency interface are controlled, in connection this Bright, it is possible to directly controlled rotation and the radio frequency of probe in test system on computers by simple and clear desktop application program The break-make of interface, thus realize control and more accurately DATA REASONING easily, it has been also prepared for a standby radio frequency interface simultaneously, To prevent one of them interface from the used time can not can also carry out gamut detection.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely retouched Stating, certainly, described embodiment is only a part of embodiment of the present invention rather than whole embodiments, based on the present invention Middle claim, in addition to embodiment but belong in right, also belong to the scope of protection of the invention.

As shown in Figure 1, hardware circuit of the present invention mainly by usb data interface 1, single-chip microcomputer 2, field programmable array FPGA3, The compositions such as data storage 4, level shifting circuit 5, interface circuit 6 and peripheral power supply circuits.

As shown in accompanying drawing 2, Fig. 3, the model selected by single-chip microcomputer 2 is the CY7C64613 of Cypress company, field-programmable Signal selected by array FPGA3 is the EP1K100FC256-3N of ALTERA company, and selected by data storage 4 is flash Chip, model is AM29LV800BB, and chip model used in level shifting circuit 5 is MAX202E.

The interface circuit of the present invention in addition to the usb circuit 1 being connected with usb data interface, also DB15/DB26 interface Circuit, DB-15 Yu DB-26 is the model of serial ports, and connected with DB-15 by Serial Port Line is radio-frequency switch circuit, and DB-26 connects Be electrical switch and control box, control box motor is controlled, thus control probe rotation.

Control signal is passed directly to single-chip microcomputer 2 by usb circuit from computer, and single-chip microcomputer 2 is again by the place of internal processes Reason converts thereof into the level signal that FPGA3 can directly read, and the data signal that reading FPGA3 sends simultaneously is fed back To computer, after FPGA receives control signal, then it is forwarded directly to each self-corresponding circuit interface 6 through inter-process (DB15) on, circuit interface 6 sends it to institute's radio-frequency switch circuit again, controls the break-make of radio circuit.

Or be the part directly transferring it to another interface circuit 6 (DB26) equally, control the break-make of electrical switch, with Time another part control signal access after level shifting circuit access interface circuit (DB26) again, then change into RS232 interface and control Box connects, and allows control box receive data and carries out corresponding action, thus reaches to control the purpose of probe.

It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted, and institute There are these modifications and variations all should belong to the protection domain of claims of the present invention.

Above in conjunction with accompanying drawing, patent of the present invention is carried out exemplary description, it is clear that the realization of patent of the present invention is not by above-mentioned side The restriction of formula, if the various improvement that the method design that have employed patent of the present invention is carried out with technical scheme, or the most improved by this Design and the technical scheme of patent of invention directly apply to other occasion, all in protection scope of the present invention.
