Modeling of multilevel control system based on Event-B

Abstract

Abstract Aiming at the problems existing in the traditional development method of multilevel control system, this paper proposes a formal modeling solution based on Event-B from the perspective of practical application. Based on the analysis of four synchronization modes and the principle of multilevel control system, a formal method is introduced. On this basis, by formulating the refined strategy of the multilevel control system model, the iUML-B model meeting the security requirements is established step by step. Through the automatic transformation function of the Rodin, the iUML-B model of multilevel control system is automatically transformed into Event-B mode. In order to ensure the safety of the system, this paper uses the ProB to simulate and record the event trajectory. The results show that the formal modeling method based on Event-B greatly improves the security and development efficiency of industrial control.
