Multi-node sequential control method based on SCADA system

Abstract

The invention discloses a multi-node sequential control method based on an SCADA system. According to the multi-node sequential control method based on the SCADA system, the sequential control method combining tree-shaped pre-configuration and an object logic expression attribute is adopted to reduce the workloads of multilayer configuration of a tree-shaped structure, a sequential control logic analyzer can calculate the logic results of sequential control node objects according to logic conditions of the sequential control node objects, and a main algorithm is that the recursive algorithm of a stack and the recursive algorithm of a queue are utilized for calculating the logic nifix expression. According to the multi-node sequential control method based on the SCADA system, the sequential control objects are classified, a sequential control node of a result type is defined as a key point of sequential control events, one effect of the sequential control node is that the sequential control node serves as a judge condition for subsequent sequential control execution and can simplify the logical expression configuration of other sequential control object nodes, and the other effect of the sequential control node is that the sequential control node outputs a sequential control milestone result and judges whether the sequential control is stopped or not; a sequential control node of a condition type is defined as a precondition of the sequential control objects, and diversity of conditions including digital quantity, analog quantity, pulsed quantity and other forms is achieved.
