[0002] With the increasing demand for parallel operation of multiple operating systems, embedded systems and smart devices have been widely used in industrial control, Internet of Things, smart home and other fields. Multiple operating systems of different platforms often need to run on the same hardware device to meet the requirements of complex task processing and multi-functional systems. However, hardware resource sharing, compatibility management and real-time guarantee between multi-platform operating systems have become technical bottlenecks. Traditional technical solutions are difficult to meet the requirements of efficient and secure parallel operation of multiple operating systems.

The multi-platform operating system compatible system based on the core board according to claim 1 is characterized in that: The system monitoring module includes: a real-time monitoring mechanism module, a fault diagnosis mechanism module and a dynamic adjustment function module; wherein: The system monitoring module dynamically detects the hardware resource usage of each operating system based on the real-time monitoring mechanism module, and adopts periodic sampling technology to achieve resource scheduling efficiency under a set load state; The system monitoring module detects abnormal behaviors in each of the operating systems through the fault diagnosis mechanism module and records logs; In the case of insufficient system resources, the system monitoring module dynamically adjusts resource allocation of each operating system based on the dynamic adjustment function module.

9. The multi-platform operating system compatible system based on the core board according to claim 1, characterized in that: The core board module supports multiple processor architectures, including x86, ARM and RISC-V architectures. The core board module optimizes resource scheduling and manages each operating system according to the instruction sets of different processor architectures.

10. The multi-platform operating system compatible system based on a core board according to any one of claims 1 to 9, characterized in that: The core board module is used to simultaneously carry at least two of the operating systems of Windows, Linux or Android.
