Abstract

The invention belongs to the technical field of aviation motor control, and particularly relates to an aviation alternating current starting controller data recording method and system. The method comprises the following steps: S1, taking a first partition of a to-be-stored space as a storage partition; s2, acquiring a start address and a tail address of the storage partition; s3, acquiring data of the aviation alternating current starting controller in real time, and circularly writing the data into the storage partition from the initial address to the end address of the storage partition until the aviation alternating current starting controller is monitored to enter a fault state; s4, continuously recording the data of the aviation alternating current starting controller within t2 seconds in the storage partition; and S5, taking the next partition of the to-be-stored space as a new storage partition, and repeating the steps S2-S4. According to the method and the device, the fault data can be independently stored during starting each time, the fault data can be quickly positioned, unnecessary space occupation is reduced, and the utilization rate of memory resources is improved.

Description

Technical field

[0001] This application is attributable to the air motor control, and more particularly, to a starter alternator aviation data recording method and a system controller. Background technique

[0002] Air exchange start controller is controlled in accordance with numerical control system commands the motor starter. After starting, the starter alternator driven by an engine start controller, to achieve the desired rotational speed, the starter alternator power converter controller controls the starter contactor is opened, the end of the starting process. The controller starts the process, it is inevitable failure, especially in order to protect the stability activatable having technical requirements of aerospace repeatedly starting the starter alternator controller. This requires the controller includes a data recording function, the designer in order to facilitate the subsequent failure analysis can be recorded a plurality of times required starting fault data.
