Description

Landing comprehensive tester made in Russia

Technical field

The present invention relates to a kind of airmanship, particularly a kind of landing comprehensive tester made in Russia.

Background technology

Blind landing landing equipment made in Russia needs daily servicing and detection behind the equipment of airport.But the measurement of complete machine needs collator to detect, and costly, the stand-by period is grown and can't detect at any time.Only there is at present the measuring equipment of test section function can't finish daily detection in the world, and only can manually controls and select to measure direction-finding signal the complete machine all functions.

Summary of the invention

In view of the deficiency that prior art exists, the present invention provides a kind of landing comprehensive tester made in Russia for reducing detection difficulty, finishing the measurement content.

The present invention for achieving the above object, the technical scheme of being taked is: a kind of landing comprehensive tester made in Russia, it is characterized in that: comprise the FPGA module, ARM chip, display screen, DSP computing module, A/D module, the transceiver module that join with button, circuit in the described FPGA module is set to, and the working method control and executive module is connected apart from comprehensive module, frequency measurement module, A/D buffering fifo module with transceiver module control, side respectively; Described ARM chip respectively with display screen and FPGA module in the working method control and executive module, the bidirectional data buffer module connects, described DSP computing module respectively with the bidirectional data buffer module, A/D cushions fifo module, the frequency measurement module, the comprehensive module of finding range connects, the control of transceiver module in the FPGA module respectively with described transceiver module in range transmitter, ranging receiver, the blind landing receiver connects, the comprehensive module of finding range respectively with range transmitter, ranging receiver connects, the frequency measurement module respectively with range transmitter, ranging receiver, the blind landing receiver connects, A/D buffering fifo module is connected with the A/D module, the A/D module respectively with the blind landing receiver, ranging receiver connects, the blind landing receiver, ranging receiver, range transmitter is T-Ring shape duplexed antenna respectively.

The invention has the beneficial effects as follows: 1, can convenient and swift and comprehensively detect Devices to test; 2, can provide outfield and internal field measuring ability; 3, easy to operate, being easy to carry is fit to the field work use.

Embodiment

As shown in Figure 1, landing comprehensive tester made in Russia, comprise the FPGA module, ARM chip, display screen, DSP computing module, A/D module, the transceiver module that join with button, circuit in the described FPGA module is set to, and the working method control and executive module is connected apart from comprehensive module, frequency measurement module, A/D buffering fifo module with transceiver module control, side respectively; The ARM chip respectively with display screen and FPGA module in the working method control and executive module, the bidirectional data buffer module connects, the DSP computing module respectively with the bidirectional data buffer module, A/D cushions fifo module, the frequency measurement module, the comprehensive module of finding range connects, the control of transceiver module in the FPGA module respectively with described transceiver module in range transmitter, ranging receiver, the blind landing receiver connects, the comprehensive module of finding range respectively with range transmitter, ranging receiver connects, the frequency measurement module respectively with range transmitter, ranging receiver, the blind landing receiver connects, A/D buffering fifo module is connected with the A/D module, the A/D module respectively with the blind landing receiver, ranging receiver connects, the blind landing receiver, ranging receiver, range transmitter is T-Ring shape duplexed antenna respectively.

Principle of work: transceiver module inside is divided into blind landing receiver, ranging receiver and range transmitter passage, the blind landing receiver channel receives blind landing (course, the downslide extension set) signal of Devices to test emission, finishes the timesharing of course and downslide for subsequent module and measures; The ranging receiver passage receives the answer signal of Devices to test emission, and the range transmitter passage sends interrogating signal to Devices to test, the range finding sense channel of range transmitter passage and ranging receiver passage acting in conjunction simulation verification aircraft; ARM, button and display screen are finished the control operation of system and Presentation Function; Control, data acquisition, data computation, the modulation signal that FPGA module associating DSP computing module is finished transceiver module jointly produces, distance measuring signal resolves and the measuring ability of carrier frequency frequency.

This scheme has realized following function:

A, time-sharing multiplex are finished the synchronous detection of blind landing (course, downslide extension set) audibility coefficient.

B, directly export the distance measuring signal outfield and detect with the internal field and detect the test signal that needs, and can 1dbm be that output signal power is regulated in stepping in-85 ~ 30dbm scope.

C, simulation verification aircraft function are finished distance measurement function in real time.

The detection of d, increase ranging receiver dynamic range and sensitivity.

E, increase range finding extension set sign indicating number type and decoding ability measuring ability.

F, can finish radio frequency channel automatically and detect and signal code type matching feature.

G, can store and call the detection data.
