Technical Field

[0001] The utility model relates to the technical field of flight test and testing, in particular to an aircraft tail-warping signal alarm display system. Background Art

[0002] With the development of aircraft flight test technology, airborne test systems have received increasing attention. Among them, airborne test systems used to test the minimum takeoff speed of the aircraft, the misoperation takeoff test, and the maximum available rate nose wheel lift test are particularly important for the aircraft takeoff attitude limit test. In the aircraft takeoff attitude limit test, it is necessary to observe the aircraft attitude in real time, make a quick judgment, and adjust the aircraft attitude in time. At this time, the airborne test equipment needs to have good real-time and intuitiveness.

[0003] Existing equipment can only extract and output data from the aircraft's tail tilt radar sensor and travel sensor. The pilot needs to compare the output sensor data with the safety value, which is not intuitive enough. Then, the pilot needs to make adjustments to the aircraft's attitude, which is not real-time enough. As a result, when the aircraft's attitude is adjusted, the aircraft's tail tilt has been severely damaged, and accurate minimum takeoff speed test flight, misoperation takeoff test flight, and maximum available front wheel lift test flight data cannot be obtained.

[0008] Furthermore, the serial port data receiving module is connected to the serial port data processing module, which processes the user configuration data and the two sensor data and sends them to the NorFlash configuration storage module, which is used to read and write the user configured threshold information on the NorFlash storage chip; the NorFlash configuration storage module is connected to the display control module, which is used to determine whether the aircraft radar sensor and travel sensor data exceed the user configured threshold range, and output the judgment result to the traffic light display module, and the traffic light display module performs an alarm display.

[0009] Furthermore, the serial port data receiving module includes a sensor data receiving module and a configuration data receiving module.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] This embodiment provides an aircraft tailskid signal alarm display system, which includes a tailskid system control box, a PC, a main control module, and a red and green light display module; as shown in Figure 1 as follows.

[0020] As an implementation manner in this embodiment, the tailskid system control box is used to collect the data of the aircraft tailskid radar sensor and the travel sensor, and after packetizing it, output it in the form of RS232.

[0021] As an implementation manner in this embodiment, the PC is used for the user to send configuration instructions. After installing serial port software on the PC and editing the corresponding configuration instructions, output them in the form of RS232.

[0022] As an implementation manner in this embodiment, the main control module is used to receive the RS232 serial port data output by the tailskid system control box and the serial port configuration data of the PC, extract the sensor data and the threshold information configured by the user therein, and judge whether the data of the radar sensor and the travel sensor exceed the threshold configured by the user, and control the red and green light display module to perform alarm display according to the judgment result.

[0023] Specifically:

[0024] The serial port data receiving module is used to control two RS232 serial ports to respectively receive the sensor data output by the tailskid system control box and the user configuration data output by the PC.

[0025] The serial port data processing module is used to parse the two parts of serial port data. One part is the user configuration data, and according to the configuration protocol, extract the threshold information of the radar sensor and the travel sensor configured by the user therein, and send it to the NorFlash configuration storage module; the other part is the sensor data, and according to the RS232 data parsing protocol, extract the real-time data of the aircraft radar sensor and the travel sensor therein, and send it to the display control module.

[0026] The NorFlash configuration storage module is used to read and write the threshold information configured by the user on the NorFlash storage chip.

[0027] The display control module is used to judge whether the data of the aircraft radar sensor and the travel sensor exceed the threshold range configured by the user, and control the red and green light display module to perform alarm display according to the judgment result.

[0028] As an implementation manner in this embodiment, the red and green light display module adopts high-brightness, adjustable red and green display lights, which are used for the pilot to directly view the takeoff and touchdown conditions of the aircraft, so as to adjust the aircraft attitude in time.

[0029] As an implementation manner in this embodiment, the main control module includes a serial port data receiving module, a serial port data processing module, a NorFlash configuration storage module, and a display control module.

[0030] The specific process of the serial port data processing module of the present utility model is as follows: First, check whether the data type is sensor data or configuration data; if it is sensor data, extract the radar signal value and the travel signal value therefrom according to the RS232 data parsing protocol, and send them to the display control module; if it is configuration data, parse out the threshold information of the radar sensor and the travel sensor configured by the user therefrom according to the configuration protocol, and send it to the NorFlash configuration storage module, as Figure 2 shown.

[0031] The specific process of the display control module of the present utility model is as follows: First, read the radar threshold 1, travel threshold 1, and radar threshold 2 configured by the user through the NorFlash configuration storage module; determine whether the radar signal value output by the serial port data processing module is less than or equal to the radar threshold 1. If the radar signal value is less than or equal to the radar threshold 1, output a high level through IO port 1 to control the green light to turn on. Otherwise, output a low level through IO port 1 to control the green light to turn off; determine whether the travel signal value is greater than or equal to the travel threshold 1 and whether the radar signal value is less than or equal to the radar threshold 2. If the travel signal value is greater than or equal to the travel threshold 1 and the radar signal value is less than or equal to the radar threshold 2, output a high level through IO port 2 to control the red light to turn on. Otherwise, output a low level through IO port 2 to control the red light to turn off, as Figure 3 shown.

[0032] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
