In order to achieve suitable environment to cultivate animal cells

a bioreactor monitoring and control system base on PLC was designed.The hardware design and control system is explained in detail through the design idea of the control system

the analysis of measuring and control point numbers

the hardware structure

the parameters detection

the executive components

the integration of upper and lower computer hardware system.The experimental results shows that the hardware of the control system is configured reasonably

the operation of control system is reliable and stable and it is easy to use.The temperature

pH and DO can be controlled effectively by the system.The system can meet the requirement of process control of cell cultivation.
