Abstract
The utility model provides a ADS_B tester, includes the host computer, shows the accuse terminal, the host computer is connected through net gape or serial ports between the terminal with apparent the accuse, perhaps directly link the radio frequency cable sends test signal to ADS_B receiving equipment to the tester through the antenna, tester host includes frequency synthesizer, and programmable attenuator, signal processing board and power module, its characterized in that are surveyed ADS_B receiving equipment and pass through network or serial port connection ADS_B tester, constitute the closed loop test system.
Description
Technical field
The present invention relates to a kind of ADS_B tester.
Background technology
ADS_B tester is by sending simulation ADS_B association message and interference signal, and to verify, the function of test ADS_B receiving equipment and performance, also can be the maintenance of ADS_B receiving equipment and the use of examination simultaneously.This tester supports that user inputs the related content of ADS_B information (DF17/18) message, the A/C pattern message supporting user to input transmission rate and content can to arrange, the interference signal type such as burst pulse, continuous wave that transmission rate and pulse duration can be arranged.ADS_B tester can carry out automated closed-loop test and semi-automatic test.
Summary of the invention
In order to solve prior art Problems existing, the invention provides a kind of ADS_B tester, comprise main frame, aobvious control terminal, is connected by network interface or serial ports between main frame with aobvious control terminal, described tester by antenna or linear radio-frequency to ADS_B receiving equipment, described tester main frame comprises frequency synthesizer, programmable attenuator, signal-processing board and power module, is characterized in that described ADS_B tester sends unlike signal mixing output by arranging two passages.
Tester as above sends out signal scene assorted by the message such as position, speed, the state simulation of the multiple target of Mass production is actual, and tests process capacity and the data throughput capabilities of ADS_B receiving equipment with this.
Tester as above can judge the correctness of packet parsing by the coding result contrasting ADS_B tester coded data and tested ADS_B receiving equipment.
Tester as above, by closed loop test mode, contrast sends and time of reception can realize the process time delay testing ADS_B receiving equipment.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
ADS_B tester is in strict accordance with the requirement of ICAOANNEX10, RTCADO-260, RTCADO-260A/B, EUROCONTROLASTERIXCategory021 related specifications, and in conjunction with ADS_B receiving equipment testing requirement, airborne answering machine or ADS_BOUT equipment transmitting ADS_B signal (DF17/18), A/C signal and interference signal can be simulated in batches, realize testing the receptivity of ADS_B receiving equipment.ADS_B tester supports that user oneself arranges message interval time, tranmitting frequency, and transmitted power level supports Ethernet and serial communication.
As shown in Figure 1, ADS_B tester comprises main frame, aobvious control terminal, is connected between main frame with aobvious control terminal by network interface or serial ports.Tested to as if ADS_B receiving equipment, send test massage to equipment under test by antenna or direct-connected radio frequency cable.
If accompanying drawing 2 is with shown in accompanying drawing 3, tester main frame is made up of frequency synthesizer, programmable attenuator, signal-processing board, power module.
ADS_B tester of the present invention can test ADS_B receiving equipment signal handling capacity, project broken down as follows:
● target disposal ability (process capacity)
● anti-interference rejection ability
● packet parsing correctness
● process time delay
ADS_B tester by the message simulation such as position, speed, the state actual complex signal scene of the multiple target of Mass production, and tests process capacity and the data throughput capabilities of ADS_B receiving equipment with this.ADS_B tester realizes the interference environments such as simulating multi-path, A/C, random pulses by arranging two passages transmission unlike signal mixing outputs, and tests the anti-interference rejection ability of ADS_B receiving equipment with this.The correctness of packet parsing can be judged by the decoded result contrasting ADS_B tester coded data and tested ADS_B receiving equipment.By closed loop test mode, contrast sends and time of reception can realize the process time delay testing ADS_B receiving equipment.Test connection diagram as shown in Figure 4.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
