Problems solved by technology
This method is simple, but there are major disadvantages, mainly because there are too many branches in the process of software operation, and the code is redundant. In some extreme cases, it can cause branch execution errors, which will cause abnormal operation of the electromechanical system and affect the safety of the aircraft.

Embodiment Construction
[0012] The partitioned operating system includes at least the integrated task management partition, the ground maintenance partition and the IBIT partition. The application layer software determines the execution sequence and execution time of each partition by configuring the time schedule of the core operating system. Based on the ground maintenance and IBIT function call method of the electromechanical system management software of the airborne partition operating system, and based on the working principle of the airborne partition operating system, in the design of the electromechanical system management software, the ground maintenance and IBIT functions of the aircraft electromechanical system are individually assigned to a certain partition implement. According to the status of the aircraft (air or ground), trigger the time schedule table of the core operating system to switch in real time, and complete the ground maintenance of the aircraft electromechanical system and ...

The invention belongs to the field of airborne electromechanical system software application, and relates to an electromechanical system software architecture based on an airborne partition operationsystem. Wherein the partition operation system at least comprises a comprehensive task management partition and a ground maintenance and IBIT partition, and the application layer software determines an execution sequence and execution time of each partition by configuring a time schedule of the core operation system; When the comprehensive task management partition judges that the aircraft state is in the air, the core operation system forbids ground maintenance and the IBIT partition is scheduled by configuring a core operation system time scheduling table; And when the comprehensive task management partition judges that the aircraft state is the ground, the core operation system starts ground maintenance and IBIT partition scheduling by configuring a time scheduling table of the core operation system. The problems of ground maintenance and IBIT function scheduling of an aircraft electromechanical system can be effectively solved, it is ensured that an aircraft cannot execute ground maintenance and an IBIT function in the air, airborne software code redundancy is avoided, and the safety of electromechanical system management software is improved.
Description
technical field [0001] The invention belongs to the application field of airborne electromechanical system software, and relates to an electromechanical system software framework based on an airborne partition operating system. Background technique [0002] With the continuous improvement of the integration of airborne electronic equipment, the airborne electromechanical system management computer works to complete the monitoring function of each subsystem of the aircraft electromechanical system. The ground maintenance and IBIT function of the aircraft electromechanical system are important means to complete the aircraft platform maintenance and the fault diagnosis of the electromechanical system equipment. The ground maintenance and IBIT function of the aircraft electromechanical system are only allowed to be carried out under ground conditions. It will pose a serious or even devastating threat to the safety of the aircraft. Therefore, ensuring that ground maintenance and...
