The utility model content
The utility model has overcome shortcoming of the prior art, a kind of central synthesis display component detection system is provided, can satisfy maintenance, troubleshooting and the test of central each parts of integrated display system, be applicable to that institutes such as the mainstream model Boeing of present domestic civil aviaton unit and Air Passenger adorn central synthesis display parts.
The technical solution of the utility model is: a kind of central synthesis display component detection system, comprise central processing unit, input-output apparatus that is connected with central processing unit and multiple-grooved telescopic backboard, on the multiple-grooved telescopic backboard, be connected with ARINC429 bus card, ARINC568 bus card, D/S card and expanded circuit integrated circuit board, these card connection are to terminal strip, terminal strip is connected successively with the interface socket of test adapter, measured piece, the signal source in addition that is connected with test adapter.
Described test adapter comprises the signal adapter circuit and adjusts circuit.Described terminal strip is a bus adapter.Described signal source comprises voltage and current signal, synchronizing signal, ARINC signal.
Compared with prior art, the utility model has the advantages that: can finish maintenance, troubleshooting, the performance test of airborne central authorities each parts of synthesis display, have advanced automatic control function, sophisticated software test, guaranteed airborne comprehensively land assembly in real time, test accurately and rapidly; And the utility model also has self-test and calibration function, can guarantee that system self works reliably.Use synthesis display unit test system of this airborne central authorities, can improve maintenance, detection efficiency, guarantee the integrity of aviation airborne equipment, ensure aircraft safety, high efficiency flight.Airborne central authorities synthesis display parts are the important display devices on the modern aircarrier aircraft, are the equipment of high value, high integrated technology.All be that the maintenance shop of delivering to external or OEM is repaired in the past, cost of repairs height, the cycle is long, can not guarantee the natural rate of interest of airline flights.Of the present utility model coming into operation can be improved domestic maintainability, for airline saves cost, has good society and economic benefit.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a test macro block diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of central synthesis display component detection system, comprise: comprise central processing unit, input-output apparatus and multiple-grooved telescopic backboards such as the keyboard that is connected with central processing unit, display, printer can be exported the expanded circuit integrated circuit board of various discrete magnitudes; And on the multiple-grooved telescopic backboard, be connected with ARINC 429 bus cards that are connected with T1200 bus analysis instrument, ARINC568 bus card, D/S card etc., these card connection are to terminal strip, terminal strip is connected successively with the interface socket of test adapter, measured piece, wherein test adapter comprises the signal adapter circuit and adjusts circuit, the signal source in addition that is connected with test adapter provides the essential voltage and current signal of test, synchronizing signal, ARINC signal etc.
Terminal strip can be a bus adapter.Because each parts of the central synthesis display of multiple different model are housed on Boeing and the Air Passenger aircraft at present, thereby for the central synthesis display parts that guarantee different model all can insert this test macro and need not to change the general purpose test equipment internal circuit, test macro adopts the special test adapter to connect measurand and test macro.The comprehensive landing assembly that existing civil aviation aircraft is installed all is the record equipment that Rockwell Corinth and Honeywell produce basically, all satisfies the ARINC700 series of canonical in the design.This has just guaranteed that the interface of the central synthesis display parts of the different piece numbers that different company produces, the signal of cable all can insert common apparatus, just select different adapters for use according to different model.
Adjust circuit and will adjust to suitable amplitude, send into terminal strip from the alternating current-direct current signal of the next varying level of special test interface.
But concrete tested object piece number has: 312EDP-XX, 212EDP-XX, C16221XXXX, H341-XX, 772-5005-XX, WL102-XX, H150-XX etc.
This central synthesis display unit test system is according to the testing requirement of measured piece UUT, provide/receive required ARINC429 bus signals, ARINC568 bus signals, discrete magnitude signal, synchronously/revolve varied angle signal etc., and receive to handle the various signals of instrument output, adopt man-machine dialog interface intuitively to finish the test of central synthesis display parts.
The software of also useful C language independent development is so that operation and maintenance, and the software of independent development can carry out fault diagnosis to each parts of central synthesis display of being tested by hardware, analyze and accurately fault location reason and parts.
The software systems of this central synthesis display unit test system mainly by testing apparatus drive, test execution control, modules such as self-test and correcting device, subsidiary function are formed.
The testing apparatus of software systems drives the driver that mainly comprises all plug and play integrated circuit boards, and the programming of softpanel and soft interface with two system extension, is reserved with test driver and soft interface for convenience.
Test execution control in the software systems: be that testing apparatus and flow process are controlled, load pumping signal, and point out test process and test result in the process of implementation.
After starting central synthesis display unit test system software, enter graphic interface, click and enter central synthesis display unit test system and carry out self-test and calibration, employed equipment, bus card are carried out self-test and calibration.After system self-testing success, carry out comprehensive landing assembly master test procedure, select the piece number of tested equipment, and after input sequence number and the repacking number, finish test automatically, and test result is stored.
