[Objective]In order to improve the culture parameter control ability of the microalgae photobioreactor,an advanced and stable microalgae culture measurement and control system has been established to improve the microalgae production yield and quality.[Method]Through analyzing the parameters of the microalgae cultivation process,the monitoring parameters and control parameters of the proposed integrated measurement and control system were defined,and a universal integrated measurement and control system was designed and developed.Then a complete microalgae cultivation test was carried out.[Result]The system was running stably,and the changing trends of light,temperature,pH and dissolved oxygen were mutually confirmed.The chlorophyll fluorescence parameters and RGB spectrum well reflected the physiological state of the microalgae cell photosynthesis system.The automatic OD measured by the system had a good linear relationship with the dry weight,which could directly reflect the growth density of microalgae.[Conclusion]The microalgae integrated measurement and control system has reasonable design,stable operation and high degree of automation,which well reflects the status and trend of the microalgae production process,and realizes the controllable cultivation of the microalgae production process.
