The simulation method of the decentralized control system specifically comprises the following steps that a plurality of clamping pieces are added into a decentralized processing unit to serve as simulation clamping pieces, logic is generated in a logic controller to enable the simulation clamping pieces to achieve the simulation function, and the simulation function comprises simulation of fieldequipment and simulation of the corresponding technological process. The analog card pieces are connected with the corresponding basic card pieces for realizing control and monitoring functions through signals. Simulation of the decentralized control system is realized through an operator station. According to the simulation method of the distributed control system provided by the invention, the field equipment and the technological process can be simulated with lower use cost. The invention also relates to a corresponding decentralized processing unit and a decentralized control system.
Description
technical field [0001] The present invention relates to a simulation method, in particular to a simulation method of a distributed control system, and a distributed processing unit and a distributed control system related to the simulation method. Background technique [0002] Distributed Control System (DCS for short) is widely used in industrial control. In order to improve the operation and maintenance level of operators, DCS is usually equipped with simulation functions to achieve training for operators. Existing DCS generally adopt physical simulation or additionally configure the simulation system to realize the simulation function. Physical simulation can generally only be simulated to the level of field equipment, and cannot realize the simulation of the process, and the additional simulation system will lead to an increase in the cost of use. Contents of the invention [0003] The purpose of the present invention is to provide a simulation method for a distribut...
