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

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
