The grade of the service life piece is determined according to different consequences and influences generated by the fault of the service life piece, and the specific classification standard is as follows:
the class A is a key life-prolonging part, and the flight safety is directly influenced by the product failure;
the B type is an important life part, and the failure of the product does not directly affect the flight safety but directly affects the completion of the task;
class C is a general life piece, and product failure does not directly affect flight safety and task completion.
For C-type products, because the failure of the products does not directly affect the flight safety and the completion of tasks, the service life control can be cancelled, and a mode of maintenance according to the conditions is adopted.
For products of A, B category, the indexes of prolonging can be comprehensively analyzed according to the service conditions of troops (maintenance experience and fault statistics), the overhaul condition of the major repair factory of the airplane, the product development condition and the wear condition of the products with the service lives, and the service lives of some parts are evaluated by applying a reliability statistical theory.
For the class A products, considering that the flight safety is influenced after the functional failure occurs, the class A products are mainly tested and assisted by an external field information method and an engineering analysis method; for B-class products, the external field information method and the engineering analysis method are mainly used in consideration of influencing tasks after functional faults occur, and tests are supplemented if necessary.
Constructing a periodic task library:
and forming a corresponding periodic task library aiming at the service-part list formed after the service-part maintenance. Each service life part has its own periodic task, and the task defines the maintenance period, trigger condition, task execution content and other information of the periodic task.
Generating a periodic work list:
the method for generating the periodic work list comprises the following steps of judging whether an original data set for airplane test flight reaches a first trigger threshold value or not: s301: acquiring an acquired airplane test flight original data set; s302: judging whether the original data set of the airplane test flight reaches a first trigger threshold value or not; s303: and if the original data set of the airplane test flight reaches a first triggering threshold value, extracting a periodic work list of the service-life piece according to a periodic task library.

And (3) periodic task scheduling management:
as shown in fig. 4, the system periodic task scheduling management includes the following steps:
(1) task waiting
Once the task is decomposed, the task enters a waiting state, and a scheduling strategy determines when the task can be triggered and activated;
(2) task activation
After the task enters the waiting state, firstly sending a notification message to the task management pool to request the task management pool to allow the task management pool to enter, determining whether the task is allowed to be activated or not by the management pool through a task receiver, and if the task meets the activation condition, immediately recording the task thread state by the task management pool and putting the task thread state into the task management pool; if the task thread does not accord with the activation condition, the task thread is rejected by the task receiver, is still in a waiting queue and keeps a waiting state;
(3) task readiness
When the task thread enters the task management pool and is in an active state, the task management pool suspends the task, and the task is considered to be active but can not be executed. The management pool does not trigger the task and the task is triggered by the management pool because the task may have timing trigger; when a task thread reaches a trigger condition, a task firstly sends a notification message to a task management pool to request the task management pool to queue, the task management pool judges whether the task can be queued or not, if the task thread meets an execution condition, the task management pool immediately records the task thread state and puts the task thread state into a ready queue; if the task thread does not accord with the execution condition, the task thread is rejected by the management pool, is still suspended and keeps an activated state; a task thread in a ready queue realizes a monitoring interface and waits for an execution notice of a management pool;
(4) task execution
The task management pool redistributes the tasks of the ready queue, acquires the next task to be executed from the queue according to a priority algorithm, and then sends a notification message to the task to notify the task that the task can be executed; once the task receives the notification message, the task immediately returns an execution mark to the management pool, then the executable state of the task and the currently available resources of the management pool are checked, if the execution condition is met, the task firstly sends a notification message to the management pool, at this time, the management pool does not need to judge any more, only the state of the task is recorded, and the execution mark of the task is stored;
(5) task completion
After the task is executed, whether the task is executed successfully or not, a notification message is sent to the management pool, the management pool records the state of the task thread, and reads the stored execution mark, so that the detailed information of the task execution result can be fed back. At this time, the management pool terminates the task, and since the management pool does not provide the capability of forcibly interrupting the task, the task itself must have the capability of terminating. Eventually, the management pool moves the task out.
And (3) periodic task monitoring:
the method has the advantages that the method has the omnibearing full-coverage periodic task monitoring, and the monitoring content comprises the following steps: a periodic work general list of single-aircraft; periodic work in a single airplane run; the single-time airplane periodically works in the early warning period; the single secondary aircraft does not trigger periodic work; a single aircraft performs a timeout periodic operation.
Production plan docking, execution and feedback:
and after the task is issued, the task is executed by butting with the production plan and the production execution. And after the task is executed, feeding back an execution result. And the task scheduling performs task management according to the execution result, and the monitoring platform performs task state monitoring according to the execution result so as to facilitate subsequent triggering of the task.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof.
