An RTOS includes an event processor construct. The event processor has a task priority and an event processor handler. A stack for the event processor is allocated by the RTOS. The event processor handler is called by the RTOS each time an event is posted by an interrupt request handler or another task. Once processing of the event completes, the event processor handler returns (as opposed to remaining in an infinite loop) thereby allowing the stack allocated to the event processor to not be retained on entry into a sleep state and the memory bank containing the stack to be powered down during a sleep state.

This application provides an embedded task state detection method, device, system, and storage medium. In this application, when a task transitions from a non-ready state to a ready state, the ready time of the task in the ready state is recorded. The length of the ready time represents the time during which the task cannot be scheduled. Monitoring whether a task has timed out by using the time during which it cannot be scheduled provides higher accuracy and avoids false alarms. For example, if task C is starved due to an infinite loop between tasks A and B, it will be detected when the ready time of task C exceeds a set time threshold, preventing false alarms. As another example, if task A in the system has a heavy load exceeding the CPU utilization threshold (e.g., 90%), but other tasks with lighter loads are also scheduled, the ready times of the other tasks with lighter loads will not exceed the set time threshold, thus preventing false alarms about task A's heavy load causing a scheduling timeout.

This invention relates to a highly reliable on-orbit two-dimensional rotating mechanism control method and its onboard software, belonging to the field of on-orbit two-dimensional rotating mechanism control technology. The method mainly includes the following steps: controlling the two-dimensional rotating mechanism to acquire and track the sun based on the on-orbit exploration mission and solar angle. During the control process of the two-dimensional rotating mechanism, an anomaly handling mechanism and a flexible mode switching method are implemented; a search mode is set to ensure that even under conditions where new offsets exist between the mechanical structures of the two-dimensional rotating mechanism during satellite launch, or when ground experiments cannot be completely consistent with on-orbit conditions, the remote sensing instrument can achieve the greatest possible success in acquiring the sun. These measures ensure the successful completion of the exploration mission by the remote sensing instrument. The timed waiting mechanism of the mode ensures that the two-dimensional rotating structure control process can still execute normally even when the control software returns a chaotic state, ensuring that the onboard software does not enter an infinite loop, thus guaranteeing the completion of the entire on-orbit mission.
