Description

Aircraft in-situ test equipment

technical field

The utility model relates to an aircraft testing device, in particular to an aircraft in-situ testing device.

Background technique

At present, during the in-situ test of the aircraft, the detection equipment cannot be placed in the cockpit due to volume reasons. In-situ detection requires the cooperation of two or more people. One person operates the detection equipment, and one person operates or reads the parameters on the instrument in the cockpit. Sometimes it is necessary for one person to complete the work of communicating (there is noise after the aircraft is turned on, and the person operating the detection equipment and the person in the cockpit cannot communicate in real time). A small number of devices will be equipped with "handheld terminals", all of which use wired communication. It is inconvenient to carry, and is also limited by communication distance and communication speed.

Example

As shown in Figure 1, a kind of aircraft in-situ testing equipment, this testing equipment is respectively connected with atmospheric machine 2, heading and attitude system 3 and display system 4, and described testing equipment comprises testing circuit 1, remote terminal 5 and signal simulation detection Circuit 6, the test circuit 1 is connected to the remote terminal 5 through a wireless network, and the test circuit 1 is connected to the signal simulation detection circuit 6, the atmospheric engine 2, the heading attitude system 3 and the display system 4 respectively.

The test circuit 1 is connected to the atmospheric engine 2, the heading and attitude system 3 and the display system 4 respectively through the adapter 7. Described adapter 7 comprises the atmospheric machine adapter 71 that is connected with test circuit 1 respectively, heading attitude system adapter 72 and flat display system adapter 73, described atmospheric machine adapter 71 is connected with atmospheric machine 2, described heading attitude system adapter 72 It is connected with the heading attitude system 3, and the head-up display system adapter 73 is connected with the head-up display system 4.

The test circuit 1 includes a power transmitter, a CPU, and a wireless communication board connected to the CPU, an AD/DA acquisition board, a digital IO board, an ARINC429 board and a power management module, and the wireless communication board is connected to a remote terminal , the power transmitter is connected with the AD/DA acquisition board. The test circuit is connected with the remote terminal through WIFI. The remote terminal is a tablet computer or notebook with WIFI function.

The board in the chassis receives the instructions of the CPU, and the AD/DA acquisition board sends DA signals, and part of the DA signals are amplified by the circuit board and then output to the airborne equipment; the DC voltage signal output by the airborne equipment is sent to the AD/DA acquisition after processing Board reading; the AC signal output by the airborne equipment is processed by the power transmitter and sent to the AD/DA acquisition board for reading; the digital I/O board controls the relay of the self-made circuit board; the ARINC429 board can send 429 data to the airborne equipment , and can also read the 429 signal sent by the airborne equipment.

Test circuit 1 is equipped with a WiFi communication board, which is set to access point mode. The remote terminal uses an ordinary industrial-grade tablet computer, which reduces the cost of hardware design. Any computer with WiFi function can be used as a remote terminal as long as the test software is installed, which is interchangeable. At the same time, multiple test equipment can share a remote terminal, as long as the corresponding test software is run.

When the test equipment is working, the signal simulation detection unit provides the three-phase synchronous signal and excitation for the HUD system, and simultaneously measures the three-phase synchronous signal output by the attitude system. The signal of the signal simulation detection unit is connected to the airborne equipment after being transferred by the test equipment. The test equipment provides ARINC429 signal, DA signal, DC28V power signal, switch signal, etc. for the airborne equipment. The remote terminal communicates with the test equipment through WIFI, and the operator can choose to take the remote terminal into the cockpit. Control the test equipment through the touch screen to test, output the required signal, and then read the corresponding value of the instrument in the cockpit.

Atmospheric machine testing must use testing equipment. During testing, the testing cable can be directly connected to the testing equipment, or the SPQ-3B adapter can be selected, and then connected to the testing equipment for testing after being transferred through the adapter.

Testing equipment and signal simulation testing units must be used for the testing of heading attitude system and HUD system. During the test, the detection cable can be directly connected to the test equipment, or the SPQ-4A, SPQ-5A adapter can be selected, and then connected to the test equipment for testing after being transferred through the adapter.

During the test of atmospheric engine, attitude and head-up display, the touch screen on the front panel of the test equipment can be directly used to read test data and control signal output. You can also choose to use a remote terminal to read data and control tests in a convenient place. The two devices display the test screen synchronously.

There is a test interface on the adapter panel, which can monitor the data in the test in real time, which is convenient for monitoring and fault location. The adapter and the remote terminal are optional equipment, so the flexibility is relatively large.
