Virtual Object Oriented Single-loop Control System Experimental Device

Abstract

An experimental device for a virtual object-oriented single-loop control system, comprising an industrial computer, characterized in that the industrial computer is respectively connected with a PLC regulator control ① and a PLC digital output module, and the PLC digital output module is connected with an intermediate relay, The PLC regulator control is connected to the input end of the PLC analog output module, the output end of the PLC analog output module is connected to the input end of the first-order inertia link module ①, and the input end of the first-order inertia link module ① is also connected with external interference The output terminal of the first-order inertial link module ① is connected to the input terminal of the first-order inertial link module ② and the analog input module respectively, and the output terminal of the first-order inertial link module ① is connected to the first-order inertial link module ② through the relay output node ① On the one hand, the output end of the analog input module is connected with the transition process curve module, and on the other hand, it is connected with the industrial computer to display the simulation process in real time. The invention has less investment and good teaching effect.

Description

technical field [0001] The invention relates to a teaching experiment device, in particular to a control theory and control engineering experiment device, in particular to a virtual object-oriented single-loop control system experiment device. Background technique [0002] "Process Control Engineering" is the main course of automation majors in engineering colleges after the national professional reform. ability and hands-on ability. For this reason, all colleges and universities have carried out corresponding experimental reform and construction, and its directions include two categories: one is for pure software simulation, which is not ideal at present, mainly because students do experiments with poor sense of reality; the other is for practical simulation. To construct the production process, this method requires a large investment and requires a large floor area, and is not conducive to developmental experiments. In order to strengthen the engineering characteristics ...
