The invention provides a method for avoiding repeated execution or mistaken execution of an external interrupt service function, which comprises the following steps: acquiring a trigger mode of an external interrupt, the trigger mode comprising level trigger, single-hop edge trigger and double-hop edge trigger; detecting whether a trigger level appears or not according to the trigger mode, if yes, triggering external interruption, and executing an external interruption service function; if the triggering mode is level triggering, controlling subsequent execution of the external interrupt service function through a method under the level triggering mode; if the triggering mode is double-jump-edge triggering, subsequent execution of the external interrupt service function is controlled through a method under the double-jump-edge triggering mode; if the triggering mode is single-hop edge triggering, subsequent execution of the external interrupt service function is controlled through a method in the single-hop edge triggering mode. The purpose of improving the safety and reliability of the airborne embedded equipment is achieved by avoiding repeated execution or mistaken execution of an external interrupt service function.

The present application relates to the technical field of computer, and especially relates to an environment variable configuration detection method and device, electronic equipment and medium, comprising obtaining a to-be-processed environment variable; judging whether the to-be-processed environment variable meets a preset error level trigger condition, if yes, determining it as an error level variable and generating a corresponding error prompt information, if not, judging whether it meets a preset alarm level trigger condition, if yes, determining it as an alarm level variable and generating a corresponding alarm prompt information, if not, judging whether it is a preset function environment variable, if yes, determining it as an information level variable, if not, judging whether it is a preset debugging environment variable, if yes, determining it as a debugging level variable. The present application improves the efficiency and accuracy of environment variable configuration detection.
