基于方面重组的实时软件传感器研究

Research on Real-Time Software Sensors Based on Aspect Recombination

对于日趋庞大的航电软件,其状态监控工作难以有效进行,这其中一个难点是状态监控中软件传感器的植入。由于软件传感器检测内容多为系统的行为特征,在对航电软件系统对象横切关注点的确定和方面的分离的基础上,通过软件传感器植入完成对方面的重组,最后传感器伴随着方面的织入嵌入到软件系统中。以某航电惯导系统为例详细阐述了该方法。实际应用表明,该方法对传感器植入的位置和时机的确定有指导意义。

The avionics software is growing increasingly large, and its status can not carry out monitoring work effectively. To solve this problem, based on identification of object concern point and separation of aspects in avionics software system, the aspects recom- binant by software sensors implantation is carried out. Finally, sensors are embedded in the software system with the weaving aspect. An application on fault diagnosis of INS/GNSS software system illustrates that the new method is significance for location and occasion of the sensors implantation.
