Problems solved by technology

[0003] Existing voice alarms are implemented with voice-specific microcontrollers. The control interface does not meet the requirements of the cross-link interface with the airborne anti-collision host. The use of class AB power amplifiers has a large volume and heat dissipation, and the volume cannot be adjusted according to requirements.
In addition, SD cards are often used to store alarm voices, which have the disadvantages of narrow working temperature range and slow reading speed

specific Embodiment 1

[0021] Such as figure 1 As shown, a voice warning system of an airborne collision avoidance system includes a voice storage module, a voice warning module and a voice storage and warning working state switching module; the voice storage and warning working state switching module is based on ARM processing chip STM32F429 through The interface unit of cable configuration; the voice storage module includes a serial port interface unit and a FLASH unit for storing voice information; the voice alarm module receives the type information that the upper computer needs to alarm through the ARINC429 bus, and calls the corresponding voice file on the FLASH to extract The output voice data plays the alarm voice through WM8978 and TPA3111D1 circuit.

[0022] STM32F429 receives the audio files downloaded from the debugging machine through the serial port chip MAX485, and uses the file system FatFs to store them in the serial FLASH.

specific Embodiment 2

[0024] On the basis of the specific embodiment 1, a buffer module is also included for storing the data read from the FLASH unit.

specific Embodiment 3

[0026] On the basis of the specific embodiment 2, the buffer module is a double buffer module.

Abstract

The invention provides an airborne collision avoidance system voice warning system and a voice warning method thereof. The method is characterized by, based on an ARM processing chip STM32F429 and through a serial port, receiving and storing a voice file sent by a debug machine to FLASH; and according to type information of an alarm needing to be given by an upper computer and received through an ARINC429 bus, calling the corresponding voice file on the FLASH, extracting voice data, carrying out D / A conversion and then, playing the alarm voice. The airborne collision avoidance system voice warning system and the voice warning method thereof solve the problems of narrow operating temperature range and slow reading speed, reduce size, meet requirements of a crosslinking interface ARINC429 of an airborne collision avoidance engine, and can configure the volume to improve installation adaptability of a voice alarm.

Description

technical field [0001] The invention relates to a voice warning system of an airborne collision avoidance system and a voice warning method thereof, in particular to a voice warning system suitable for an airborne collision avoidance system in the air traffic control field and a voice warning method thereof. Background technique [0002] The fundamental purpose of the airborne collision avoidance system is to ensure the safety of the aircraft on the route and effectively complete the mutual avoidance of the aircraft on the route during the flight. Through the effective tracking and monitoring of aircraft equipped with air traffic control transponders in the nearby airspace, it completes the acquisition and calculation of the target aircraft's distance, speed, flight altitude and azimuth, and generates traffic warnings correctly according to the target's trajectory, or A decisive warning is further generated according to the degree of threat, and warning information is provid...
