An object-oriented computer monitoring and testing device, which includes an industrial computer (1), characterized in that the industrial computer (1) is connected to a PLC regulator (3) and a PLC digital output module (5) respectively, and the PLC digital output The module (5) is connected to the intermediate relay (11), the PLC regulator (3) is connected to the PLC analog output module (4), and the PLC analog output module (4) is connected to an input terminal of the first-order inertia link ① (7) The other input end of the first-order inertia link ① (7) is connected to the external interference module (6), and one output end of the first-order inertia link ① (7) is connected to the first-order inertia link ② (8). The other end of the link ① (7) and one output end of the first-order inertial link ② (8) are connected to the input end of the analog input module (9), and the output end of the analog input module (9) is connected to the object Characteristic curve module (10). The invention combines actuality and virtuality with 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 an object-oriented characteristic computer monitoring and testing 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 characteristic...
