[0003] Currently, most atmospheric data computers output data in 429 data or Manchester code, while the XSC-5 atmospheric data computer uses 1553B data output.

[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Example

[0038] In the existing technology, the equipment for testing the XSC-5 air data computer is the DSQ-2103 second-line dedicated test equipment. The use of this equipment must be accompanied by specialized test software. Although it can meet the test requirements, it is expensive, has a narrow scope of application, and has technical blockade issues, making it unsuitable for the general testing and use of the XSC-5 air data computer.

[0039] Therefore, the present application provides an atmospheric data computer test system for 1553B bus data, such as Figure 1 Shown, including:

[0040] The power module and multiple analog signal devices are connected to the input terminal of the XSC-5 air data computer test bench through wires, and the analog signal devices are used to output preset analog signals;

[0041] The output end of the XSC-5 air data computer test bench is connected to the XSC-5 air data computer via a cable;

[0042] The air data tester is connected to the XSC-5 air data computer via an air pipe;

[0043] The XSC-5 air data computer communicates with the industrial computer via a data line and a 1553B bus data box;

[0044] The industrial computer is installed with test software, which is used to obtain the data protocol of the 1553B data output by the XSC-5 atmospheric data computer when it responds to different atmospheric parameters, and integrate multiple preset parameters. Based on the data protocol and all preset parameters, the 1553B data output by the XSC-5 atmospheric data computer is interpreted to obtain the corresponding atmospheric parameters, which are then displayed through the software window.

[0045] Among them, the power supply module includes a DC power supply and a programmable AC power supply. The DC power supply provides DC power for the XSC-5 air data computer test bench and the XSC-5 air data computer. The programmable AC power supply provides AC power for the XSC-5 air data computer. Specifically, it converts 115V, 400Hz AC power into 36V, 400Hz AC power, and then provides excitation voltage for the signal generator and angle indicator through the XSC-5 air data computer.

[0046] The analog signal equipment includes a signal generator, an angle indicator, and a resistance box. The signal generator and angle indicator work together to output high-precision analog pitch and azimuth signals. This means the signal generator outputs the pitch and azimuth angles internally (visual readings have poor accuracy), and the angle indicator then accurately displays the pitch and azimuth angles (e.g., to two decimal places) as output by the signal generator. The resistance box outputs an analog signal for the total temperature resistance value. The total temperature resistance signal originally refers to the electrical signal generated by the aircraft's temperature sensor when measuring the total air temperature. It is a key parameter in atmospheric data calculations and directly affects the accuracy of flight parameters such as airspeed and Mach number.

[0047] Among them, the atmospheric data tester is used to output dynamic pressure signals, static pressure signals and aircraft ascent and descent speed simulation signals. The aircraft ascent and descent speed simulation signals are directly set on the atmospheric data tester. Specifically, the dynamic pressure signals and static pressure signals are output through the air pipe to reflect the corresponding aircraft ascent and descent speed.

[0048] Among them, the XSC-5 atmospheric data computer test bench is used to: control the power input of the atmospheric data computer; remote control of the atmospheric data computer, as well as discrete signals such as self-test, sky / ground, non-compensation, reset, display, maintenance, total temperature sensor signals and pitch angle and azimuth angle inputs; internal power output of the atmospheric data computer and fault indicator light display of bus fault, GSS fault, XSC fault and system fault.

[0049] Among them, such as Figure 2As shown, the test software is used to obtain the data protocol of 1553B data output by the XSC-5 atmospheric data computer for different atmospheric parameters, and has built-in integrated multiple preset parameters, which include: the current weight parameter of the aircraft, field pressure binding parameter, vertical acceleration parameter, three rotation angular velocity parameters, pitch angle parameter and true heading parameter; and different atmospheric parameters include resistance value, aircraft absolute pressure altitude Hp, aircraft calibration altitude Hc, static pressure Ps, total pressure Pt, atmospheric density , airspeed parameters Vi, three-axis true airspeed Vx, Vy and Vz, total true airspeed Vt, rotor induced airspeed Vdw, static temperature Ts, total temperature Tt, angle of attack , sideslip angle , lifting speed and The reason for integrating multiple preset parameters is that some atmospheric parameters cannot be directly obtained by interpreting the 1553B data output by the XSC-5 using only the acquired data protocol. Therefore, calculations based on the built-in preset parameters are required to output the corresponding atmospheric parameters. That is, through the acquired data protocol and the built-in preset parameters, this test software can interpret the 1553B data output by the XSC-5 atmospheric data computer and obtain all the corresponding atmospheric parameters.

[0050] The process of testing the XSC-5 air data computer in this embodiment includes: Figure 3As shown: initially set the discrete switch on the XSC-5 atmospheric data computer test bench, and output the initial pitch angle signal and the initial azimuth angle signal synchronously through the signal generator and the angle indicator, and output the initial total temperature resistance value simulation signal through the resistance box; start the power module, then click the start button on the test software interface, wait for 30 seconds, observe the corresponding atmospheric parameters displayed in the software window, and complete the initialization of the test software; set the atmospheric data tester to output different dynamic pressure signals and static pressure signals, and adjust the resistance box to output different simulated total temperature resistance values, and adjust the signal generator and the angle indicator to synchronously output different pitch angle simulation signals and azimuth simulation signals, observe the corresponding atmospheric parameters displayed in the software window, and obtain the first observation result, that is, observe whether the output atmospheric parameters are consistent with the real atmospheric parameters detected by the atmospheric data computer under the same conditions (the data source is the atmospheric parameter range provided by the manufacturer); set the atmospheric data tester to output The aircraft's ascent speed is the first set value (e.g., 8 m / s) and the aircraft's descent speed is the second set value (-3 m / s). Observe in the software window whether the aircraft's ascent speed and descent speed are 8 m / s and -3 m / s, respectively. If not, it indicates a fault with the XSC-5 air data computer. Set the self-test discrete switch on the XSC-5 air data computer test bench to the ON position. Observe whether the self-test atmospheric parameter values ​​displayed in the software window meet the self-test atmospheric parameter values ​​under the actual discrete input state of the XSC-5 air data computer (the data source is the fixed input parameters (2000 meters altitude) stored internally in the air data computer. By inputting the internally predetermined parameters, test whether the output parameters of the air data computer are within the atmospheric data parameter range provided by the manufacturer). Finally, integrate the first, second, and third observation results, output the test results of the XSC-5 air data computer, and complete the test of the XSC-5 air data computer.

[0051] The atmospheric data computer test system for 1553B bus data of this embodiment uses independently developed test software and an XSC-5 atmospheric data computer test bench for manual testing, making maintenance, testing, and adjustment more convenient and quick.
