Abstract

Abstract

The behavior logic of safety digital instrumentation and control (I&C) system is carried by software, but the software reliability evaluation is relatively difficult. Therefore, in order to ensure reproducibility and timeliness of safety digital I&C system, and ensure the reliability and safety of system, behavior deterministic design is required. According to the standard requirements and combined with engineering experience, this paper puts forward the deterministic design requirements of safety digital I&C system, and from the two aspects of its certainty, puts forward that the reproducibility of the system can be guaranteed through model-based formal modeling, and the timeliness of system response can be guaranteed through the allocation of response time of each link of the system. It provides a reference for the behavior deterministic design of safety digital I&C system.
