Description

Airborne answering machine of a kind of civil aircraft or range finder are used test board

Technical field

The utility model relates to a kind of testing apparatus, especially relates to airborne answering machine of civil aircraft and range finder and uses testing apparatus.

Background technology

Answering machine (ATC) and range finder (DME) are navigator indispensable on the present generation aircraft.The principle of work of ATC is: the ground primary radar after the ATC receiver is received interrogation pulse, is answered aircraft coding and elevation information to the interrogating signal that ATC sends a 1030MHz.Installed the answering machine of aerial CAS additional, except answering the inquiry of ground primary radar, near the inquiry of aircraft also need answering, provide the coding of aircraft, highly, parameters such as course, attitude, emissive power is generally all greater than 200 watts.The principle of work of range finder (DME) is: DME transmitter guidance station earthward sends interrogating signal; Receive the reply pulse of guidance station; Send interrogation pulse to the mistiming that receives between reply pulse through calculating, confirm the distance between aircraft and the Land Navigation Installation and arrive the platform time.

Because the working time of answering machine (ATC) and range finder (DME) is long, emissive power is big, and power device and power supply unit are easy to damage because of overheated, performance degradation, and signal receiving sensitivity descends, and breaks down easily, need often detect maintenance.Common method of testing comprises that manual testing and the general purpose computer that uses manufacturer to provide detect (ATE) equipment automatically.Manual testing's mode is less demanding to testing apparatus, but strict for the personnel operation level, and the training time is long, occurs the human error easily, and stable testing property is poor.The ATE checkout equipment is reliable and stable, test complete, but its cost is higher, return period is long, has limited its usable range.

The civil aircraft kind is more at present, and the answering machine of installing on the aircraft of different type of machines is different with the range finder model, on function and connecter type, differs greatly; It is longer to adopt the manual testing to expend time in, and poor stability is if make special testing apparatus to different models; Its equipment needed thereby quantity is more, and the place area occupied is big, if adopt general ATE equipment; One time investment cost is too high, and the cost recovery cycle is long, can't promote the use of.

Summary of the invention

The purpose of the utility model provides the airborne answering machine of a kind of civil aircraft or range finder is used test board, uses this test board can connect the answering machine and the range finder of multiple model, and easy to use, equipment cost is not high.

The technical solution of the utility model is: airborne answering machine of a kind of civil aircraft or range finder are used test board; Comprise controller, some data lines, first relay control module that is connected in series respectively and power supply serial port, second relay control module and discrete signal serial port, the 3rd relay control module and communication signal serial ports and the 4th relay control module and distinctive signal serial port; Wherein first relay control module, second relay control module, the 3rd relay control module and the 4th relay control module are connected in parallel with said controller respectively; One end of every data line is provided with a signaling interface that is connected with answering machine or range finder, and the other end is provided with the capable port of substring that connects at least two ports in power supply serial port, discrete signal serial port, communication signal serial port or the distinctive signal serial port.

According to the test component signal kinds serial port is divided into power supply, discrete signal, communication signal and distinctive signal four big classes, through the break-make of each serial port of relay control module control, an end setting of data line and the signaling interface of answering machine or range finder port match; The signal of answering machine of being tested or range finder output is also classified according to power supply, discrete signal, communication signal or distinctive signal; At the capable port of the other end setting substring corresponding with each signal type, be used for connecting with corresponding serial port, make so respectively to the answering machine of different model or the data line of range finder; Just can conveniently use a test board to realize detection to dissimilar answering machines or range finder; Easy to use, the highly versatile of equipment, less investment; Shorten detection time greatly, and the accuracy of test improves.

The other end of said data line is provided with four sub-serial ports that connect said power supply serial port, discrete signal serial port, communication signal serial port and distinctive signal serial port respectively.Content measurement is comprehensive, and the data line specificity is strong.

The utility model has the advantages that: easy to use, the highly versatile of test board, the data line customizations is provided with, and has reduced the cost of investment of entire equipment, and detection speed improves, and accuracy is guaranteed.
