The test equipment can completely simulate the airplane test environment to test comprehensive performance parameters of the master warning box, ensure the quality of installing finished products, simultaneously simplifies operation procedures, and improves the working efficiency.
Description
Technical field
The utility model relates to a kind of aircraft warning system major alarm box special test equipment.
Background technology
The major alarm box is important product of aircraft warning system, for the pilot provides the system alarm signal, relates to flight safety.Existing equipment can not carry out the overall technology parameter testing to the major alarm box, the quality of the finished product that can't guarantee to install; And the operation of equipment relative complex, work efficiency is lower.
Summary of the invention
The purpose of this utility model is: propose a kind ofly can carry out all round properties parameter testing and simplified control, the higher special test equipment of work efficiency to the major alarm box.
The technical solution of the utility model is: design a kind of major alarm box special test equipment, comprise P power switch S1, R/N power selection switch S5, waver S8, reset switch S9, switch S 10, main stand by lamp L1, pilot lamp L2 and L3, multiple alarm signal etc., and on above components and parts basis, increase a reometer mA, two reometer metering jack T1 and T2, two major alarm lamp flicker frequency instrument connection T3 and T4; Reometer metering jack T1 and T2 are separately positioned on reometer mA both sides, and reometer metering jack T1 connects switch S 10, and reometer metering jack T2 connects switch S 5; Pilot lamp L2 is in parallel with L3, and frequency test hole T3 and T4 lay respectively at the two ends of L2 and L3 parallel line.
Advantage and the beneficial effect that the utlity model has are: by increasing the current sinking that reometer comes measurement section product, provide intuitive judgment when hookup or portion's product are short-circuited fault, avoid fault expansion; Increase reometer metering jack T1, T2 reometer is carried out the original position Measuring and testing, save metering cycle, use manpower and material resources sparingly; Increase frequency test hole T3, T4 and come signal is carried out sampling analysis, make the operator can adopt these signals of instrument quantitative measurment such as oscillograph or frequency meter, reduced measuring error.This testing apparatus can be used as special test equipment and comes portion's product place under repair is detected when satisfying aircraft and criticizing production verification needs.

Fig. 3 is the testing apparatus schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the improvement part schematic diagram of this special test equipment.This major alarm box special test equipment mainly comprises P power switch S1, R/N power selection switch S5, waver S8, reset switch S9, switch S 10, main stand by lamp L1, pilot lamp L2 and L3,17 tunnel alerting signals etc., and a reometer mA, two reometers metering jack T1 and T2, two major alarm lamp flicker frequency instrument connection T3 and T4 on above components and parts basis, have been increased, reometer metering jack T1 and T2 are separately positioned on reometer mA both sides, reometer metering jack T1 connects switch S 10, and reometer metering jack T2 connects switch S 5; Pilot lamp L2 is in parallel with L3, and frequency test hole T3 and T4 lay respectively at the two ends of L2 and L3 parallel line.
Fig. 2 is a testing apparatus test connection diagram, and major alarm box special test equipment is by DC power supply, and is connected with the major alarm box, and major alarm box technical parameter is tested.
Fig. 3 is the testing apparatus schematic diagram.The test job idiographic flow is as follows:
Operating temperature range: 20 ℃～55 ℃
(1) prepares before the test
A: connect exerciser and major alarm box by Fig. 1
B: each position of the switch of exerciser is as follows: switch S 2 is placed " OFF ", and S3, S4 place to upper/lower positions, and S5, S6 place the neutral position, and S10 places " NOR " position.
C: power supply :+28VDC
(2) test routine
A. connect the D.C. regulated power supply switch, check that output voltage should be+28VDC.
B. switch S 1 is placed " ON " position; system powers on; behind power supply process F1 (2A) the fuse current foldback circuit; be applied to pilot lamp L1 (24V operating voltage) end; the pilot lamp other end and power " " between be connected in series R1 (0.51K; 1/4W) be used for current-limiting protection, under the effect of potential difference (PD), pilot lamp L1 ignites.
C. switch S 5 is placed " N " position, the reometer indication should be not more than 80mA.Place " P ", S4 to place " LOAD " position S3, L2, L3 pilot lamp should glimmer, and the reometer indication should be not more than 250mA.S3 is placed to upper/lower positions, and L2, L3 pilot lamp should extinguish.This test is for carrying out P power supply oscillator inspection lamp test to the major alarm box.
D. switch S 2 is placed " OFF " position, S5 is placed the position of N power supply, S6 places the position on A-K road, stir waver S7 and be tested to the K road successively by the A road, L2, L3 pilot lamp all should be glittering, flicker frequency usable frequency meter is measured at "---F---" instrument connection, should be 1.25～2.5 hertz.
S6 is placed the position on L-b road, stirs waver S8 and be tested to the b road successively by the L road, then L2, the L3 pilot lamp all should be glittering, flicker frequency usable frequency meter is measured at "---F---" instrument connection, should be 1.25～2.5 hertz.In each passage process of the test, press reset button S9 after, pilot lamp all should extinguish.This test reaches the alerting signal frequency test for the major alarm box being carried out the test of single channel alerting signal, and every road alerting signal is selected to trigger by waver.
When E. the S5 switch being placed R power supply position, the major alarm box will be with the same manner work. the second road power supply test of this test for the major alarm box is supplied power with double circuit.
F. after test finishes, all switches are placed open position, powered-down unloads product and power lead.
Facts have proved that major alarm box special test equipment can better meet the preceding verification of the box-packed machine of major alarm and portion's product are repaired maintenance needs.
