This application provides a CAN message caching and processing architecture based on the AUTOSAR protocol stack, including: a caching module for caching received CAN messages during CAN interrupts, wherein the CAN messages include network management messages, application messages, and diagnostic messages; and a time-sharing processing function interface for execution in Tasks to implement time-sharing reading and processing of the CAN messages cached in the caching module. This architecture satisfies the time requirements for message processing while reducing processing time during CAN interrupts, preventing frequent interrupts from affecting the microcontroller's task scheduling.

The application discloses an abnormal traffic data filtering method and device, and relates to the technical field of network management intelligent operation and maintenance.The method comprises the following steps: sequentially entering the traffic data to be analyzed into a first-in first-out queue, and judging the data value abnormality by calculating the change abnormality measurement index of the traffic data when the traffic data is in the queue and when the traffic data is out of the queue; combining the data value abnormality judgment results when the traffic data is in the queue and when the traffic data is out of the queue, and finally determining the abnormality of the traffic data; and processing the traffic data finally determined as abnormal according to a preset processing strategy.The application can identify and process the abnormal traffic data in the data analysis preprocessing stage, thereby reducing the influence of the abnormal value of the traffic data on the traffic prediction and analysis work, making the abnormal value analysis and processing process of the traffic data automatic, and being self-adaptive to the change and development of the traffic data.

The invention discloses a task acceleration execution simulation method based on multi-period priority. The method comprises the following steps: S10, slow dynamic system simulation initialization: determining an original simulation period and priority of a slow dynamic system, dividing a simulation acceleration period, and setting simulation initial parameters; s20, slow dynamic system acceleration simulation: performing slow dynamic system acceleration simulation in an acceleration period according to the simulation initial parameters and the priorities to obtain simulation results of each model instance; and S30, simulation result output: outputting the simulation result of each model instance. The task acceleration execution simulation method is high in efficiency, low in cost, high in accuracy and good in universality.
