Abstract

The invention discloses a semi-physical simulation experiment system. The semi-physical simulation experiment system comprises a management layer, a control layer and a device layer. The management layer is composed of a plurality of emulation computers and is used for setting, displaying and managing an environment and parameters of a simulation experiment. The control layer is composed of a plurality of programmable logic controllers (PLC) and is used for achieving data collection, control loop regulation, sequential control, logic control and comprehensive alarm. The device layer is composed of a plurality of object devices, an imitation screen and input / output signals, and the object devices comprise sensors and actuators. A figurative expression of the system control flow chart of the imitation screen and the input / output signals are simulation input and output of a detection signal and an actuating signal of the system. The control system is downward directly connected with the sensors and the actuators of the devices layer. The input / output signals are upward connected with the emulation computers of the management layer through the network. The collected data and state signals of the object devices are transmitted to the emulation computers.

Description

technical field [0001] The invention belongs to the field of teaching technology, in particular to a semi-physical simulation experiment system. Background technique [0002] In school teaching and vocational training, experiments are an important link. Especially engineering colleges and vocational schools need to cultivate students' practical ability. Through a semi-physical simulation experiment of a control system, it can help students understand and understand a control system, which is very important for learning technology and mastering skills. [0003] The form and structure of the hardware-in-the-loop simulation experiment platform are very important for students to learn and master a control system and technology. The existing hardware-in-the-loop simulation experiment platform has two forms, the first one is to arrange the experimental console (and the simulation computer) and the real object in one, and the second is to completely separate the experimental opera...
