Delay based multi-channel and multi-priority control command voice alarm method

Abstract

In order to solve the problem that a current airborne avionic system voice alarm method is easy to generate alarm leakage and second alarm, the present invention provides a delay based multi-channel and multi-priority control command voice alarm method. The method comprises the steps of: performing 'OR' operation of valid data collected in a current round according to a defined channel collectionsequence, wherein in an alarm generation stage, an alarm command can be identified at first time to effectively avoid alarm leakage; employing an 'OR' operation result of the valid data collected in the current round and a decision result of the last round to perform 'OR' operation, forming a final decision result in the current round, wherein in an alarm ending stage, when a channel of ending thealarm recovers a non-alarm instruction, the 'OR' operation with the decision result of the last round is always performed to effectively avoid second alarm; and putting alarm instructions into a one-dimensional alarm command array according to priority levels from high to low. Therefore, the method can perform search according to the sequence and does not need searching of the whole array so as to reduce searching time and improve the response speed of an auditory sense alarm system.

Description

technical field [0001] The invention belongs to the field of airborne avionics and relates to an alarm method. Background technique [0002] There are two voice alarm methods for the existing airborne avionics system: [0003] Alarm method 1: Send commands to the auditory system through the visual alarm system, first send the command which channel is currently valid, and ensure that only one channel is always valid, and then send the alarm command, the auditory alarm system first confirms the current valid channel, and then the only valid channel The analysis of the alarm command and the voice alarm are executed in the channel. Disadvantages of this method: 1. Although there are multiple channels, only one channel is confirmed to be valid at a time. From the perspective of security, it does not actually play a role in the security of multiple channels backing up each other; 2. Increases the upper level of vision Due to the complexity of system design, the current only vali...

Problems solved by technology

[0005] In order to solve the existing voice warning method of the airborne avionics system, although it has multiple channels, it does not actually play a role in the safety of multiple channels for mutual backup, and it is easy to generate missing alarms; and solve the existing voice warning method 2 in the delay time When it is larger, it is easy to generate the problems of missing alarm and secondary alarm. The present invention provides a voice alarm method based on multi-channel multi-priority control commands with delay
