Design and implementation of a CAN-bus based pneumatic hospital tube delivery system

Pneumatic tube delivery system is an indoor logistic system in which cylindrical containers are pushed or pulled through a distributed network of tubes by fans. It can be widely used for rapid transportation of small valuable objects in modern hospital where safety and speed in a local environment is useful. The typical pneumatic hospital tube delivery system is developed based on a CAN-bus in this paper. And then, the principle, the structure and the characteristics for this pneumatic hospital tube delivery system are mainly proposed in this paper.
