Why not use RS485 or CAN bus for the communication between the slaves and the master, and the RS485 or CAN bus employs differential signals, which can be less sensitive against EMI, and they also have longer transmission length.

  1. How do you sense temperature? Also in a distributed way?
  2. What is your tentative plan for fan distribution? How many fans will you need?
  3. Can your model be used with varied chassis’ sizes and fan numbers?
  4. How will you simulate the airflow and cooling performance?

Thanks for comments. For the method to measure temperature, we will use multiple I2C-compatible temperature sensors to monitor the ambient temperature within the chassis. The sensors will be placed in a distributed way to measure the temperature of different positions. We will use four fans in our design and simulate the airflow and cooling performance with COMSOL Mulitiphysics in the next stage. Finally, to simplify our model and ensure that we can catch up with the time schedule, we will use the chassis with fixed size and fan number to verify our model.
