Based on the "integration" thought and CDIO standard of CDIO education idea, the model of laboratory system for controlling engineering in CDIO mode is studied, and the three "integration features" of the system are analyzed. Taking the construction of control engineering laboratory as an example, the overall structure and concrete connotation of the system are clarified. Three key segments of establishing laboratory system are proposed and analyzed, namely, strengthening the construction of the experimental teaching staff, innovating in the experiment management system and optimizing the approach of laboratory construction.
