Cell culture system with high-precision temperature control based on EtherCAT

With the continuous development of smart medical technology and the increasing intelligence of medical equipment, the medical device industry has been received more and more attention. To further improve the accuracy and efficiency of temperature control in cell culture system, this project has designed an overall control scheme based on EtherCAT for with high-precision. It mainly includes the design of hardware systems with PLC and ARM, as well as the software system architecture, to achieve the collection and processing of on-site signals, and the automatic control of plasma and required cell extraction and insulation. A theoretical calculation model for achieving precise control has been stablished. This system is based on the EtherCAT real-time industrial Ethernet control bus protocol, and the temperature control function is achieved through the temperature cooling, heating, and mixing module. The high-precision temperature-controlled cell culture system has strong convenience, practicality, and scalability.
