Abstract
Answering machine detection system, comprises microcontroller, input media, display, signal codec module, radio-frequency unit, and input media passes through microprocessor controls display and signal codec module, signal codec model calling radio-frequency unit.For testing military blank pipe secondary radar answering machine with the mutual communication of ground interrogation mechanism and identification mutually, promptly and accurately complete the identification to aircraft, highly, the test of the information such as critical and important technological parameters, power and the frequency of Received signal strength can be measured, adopt software control, the fault detect of self can be completed, can judge the distance of detecting distance according to output power, versatility is good.
Description
Technical field
The utility model belongs to signalling arrangement field, specifically answering machine detection system.
Background technology
Answering machine internal field detector comprises blank pipe answering machine test macro and blank pipe answering machine test macro.It is for testing military blank pipe secondary radar answering machine with the mutual communication of ground interrogation mechanism with mutually identify, promptly and accurately complete the identification to aircraft, highly, the test of the information such as critical and important technological parameters.Existing answering machine internal field detector can complete the comprehensive detection to answering machine, and substantially meets the demand of army.But use feedback to find by investigation and army, also there is a lot of defect in existing answering machine internal field detector, it is backward in technique that this mainly adopts, and existing detector adopts analogue technique, and flexible design degree is poor, and practical function is single; Sensitivity cannot be tested, and existing detector cannot complete the function of pulse signal sensitivity technique, cannot test the performance of equipment of itself; Power can not be surveyed, and the function of existing detector no-output power detection, cannot judge the distance of relative distance; The existing detector of integrated level difference does not have versatility, and the detector of a model is exclusively used in the answering machine of a certain model, and integrated level is poor; Self maintained poor performance, because detector all adopts pure analogue technique in the control of signal and generation, functionally cannot realize the inspection to the performance of equipment own, therefore, for equipment itself, whether fault cannot be located.
Summary of the invention
The utility model answering machine detection system is achieved through the following technical solutions:
Answering machine detection system, comprise microcontroller, input media, display, signal codec module, radio-frequency unit, it is characterized in that: input media is by microprocessor controls display and signal codec module, signal codec model calling radio-frequency unit, the signal that radio-frequency unit Received signal strength processing module produces.
Described signal codec module comprises encoder, and scrambler produces A/C mode query pulse and RS422 height source analog encoding signal, decoder processes aircraft coding, flying height coding, response rate and Sidelobe Suppression signal.
Described display is for showing aircraft coded message, height coded message, response rate, Sidelobe Suppression signal, transmitting-receiving frequency, emissive power, received power information.
The beneficial effect that the utility model has: for testing military blank pipe secondary radar answering machine with the mutual communication of ground interrogation mechanism and identification mutually, promptly and accurately complete the identification to aircraft, highly, the test of the information such as critical and important technological parameters, power and the frequency of Received signal strength can be measured, adopt software control, the fault detect of self can be completed, can judge the distance of detecting distance according to output power, versatility is good.
Below in conjunction with the embodiment of accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.
Accompanying drawing explanation
Fig. 1 is the utility model structured flowchart.
