Integrated modular avionics(IMA) system is widely utilized in the field of civil aircraft airborne avionics system, which is the trend in the aviation field. With the continuous innovation of the technology, the integration degree of IMA system functions is getting higher and higher. It can not only lead to more difficulties of resource allocation, but also bring challenges to the security of the system. This paper does the detailed research on the partition characteristics of IMA system and proposes a systematic behaviour and a strategy of time resource monitoring on the basis of data acquisition technology of probe instrumentation monitoring. In addition, the system architecture of data monitoring and acquisition technology was presented in this paper, which system resource monitor and time resource monitor were designed on the basis. When it comes to the implementation of resource status monitoring, the function and orientation of target and host terminal monitoring and control softwarewere clarified. In the meanwhile, the solution how to view monitoring data by software is also given in this paper. This paper has a certain guiding significance and practical value for IMA system resource status monitoring and resource allocation optimization.
