Can bus application in smart building

Abstract

Controller Area Network (CAN) bus is one of serial communication bus which support distributed control and real time control effectively. Originating from automobile industries, CAN bus slowly gain appreciation in various industries automation due to its high immunity against electrical interference and the ability to self-diagnose and repair data error. CAN bus is suitable in application requiring a large number of short messages with high reliability in rugged environment. Its application has emerges in other areas i.e security, military, aviation and electronics. This paper intends to apply CAN bus as the network to support smart building requirements. A brief introduction on CAN principles is presented. Its various applications of CAN are introduced in different researches areas. A hardware prototype for a CAN bus application is developed based on Microchip’s dsPIC30F4014 digital signal processor. The designs and implementation of the prototype system are described in details.
