Embodiment 1

[0045] like figure 1 As shown, the voice warning system for aircraft of the present embodiment includes an optocoupler isolation unit, a single-chip microcomputer connected with the optocoupler isolation unit, a voice recording and playback unit connected with the single-chip microcomputer, and respectively connected with the optocoupler isolation unit, the single-chip microcomputer and The power supply unit connected to the voice recording and playback unit.

[0046] Specifically, the optocoupler isolation unit is used to receive the landing gear warning trigger signal and the stall warning trigger signal outside the system, and output the landing gear warning signal and the stall warning signal to the microcontroller; because the landing gear warning trigger signal received by the optocoupler isolation unit The signal and the stall warning trigger signal are both 12V~14V voltage signals, and the signal that the single-chip microcomputer can process is 5V voltage, so the opto...

Embodiment 2

[0066] The present embodiment is the realization method of the voice warning system for the aircraft of embodiment 1, and it comprises the following steps:

[0067] Step 1: Initialize the system, and record the landing gear abnormal voice warning signal and the stall abnormal voice warning signal to the voice recording and playback unit through the recording input unit, and enter the warning trigger signal detection state. Specifically, recording the landing gear abnormal voice warning signal and the stall abnormal voice warning signal to the voice recording and playback unit includes the following steps:

[0068] (1) Send the abnormal voice warning signal of the landing gear and the abnormal voice warning signal of the stall to the voice recording and playback unit through the recording input unit.

[0069] (2) Enter the landing gear abnormal voice warning input control command and the stall abnormal voice warning input control command to the microcontroller through the key s...

Abstract

The invention discloses a voice warning system for an airplane, the voice warning system for the airplane is characterized by comprising an optically coupled isolation unit, a singlechip, a voice record and play unit and a power unit. The invention further discloses an implementation method of the voice warning system for the airplane, the implementation method is characterized by comprising the step 1: initializing the system, recording an undercarriage abnormity voice warning signal and a stall abnormity voice warning signal into the voice record and play unit, entering the state of detecting a warning trigger signal; and step 2, enabling the optically coupled isolation unit to detect whether an undercarriage warning trigger signal or a stall warning trigger signal is inputted, etc. Thetwo important abnormities of stall abnormity and undercarriage abnormity of the airplane are warned through voice, the differentiation degree of the warning is improved, a pilot can accurately rapidlyjudge the warning information, so that the airplane is correctly controlled.

Description

technical field [0001] The invention relates to the field of aircraft safety warnings, in particular to a voice warning system for aircrafts and a realization method thereof. Background technique [0002] The PA-44-180 provides warning signals for airframe and engine failure states. Like most general aviation aircraft, its warning signals are provided to flight personnel and ground maintenance personnel in the form of lights or buzzers; for buzzer warnings, different fault buzzer warnings are only differentiated in frequency; for Light warning. The warning light is installed on the instrument panel. It is an incandescent lamp with amber or red shade. When relevant warning information appears, the light will be on. [0003] It can be seen from the above warning methods that there are certain defects in the functional design of the PA-44-180 aircraft warning. First of all, the warning system design of the aircraft does not have redundancy, and the pilot cannot receive the wa...
