Design and verification of CAN bus based devices for parking spaces detection

Abstract

Effective and practical parking space detection significantly contribute to parking information management in the field of intelligent transportation system. Therefore, efforts are needed to develop devices to detect whether parking spaces occupied accurately and transmit data collected to parking database in real-time. In this study, devices composed of master and slave nodes based on controller area network bus are developed. Following a review on previous studies, the concept of the devices is proposed. According to the design and implementation of the devices, a comprehensive illustration on how the devices work is presented. Pilot testing experiments confirmed that the devices provide efficient and reliable parking space detection and information transmission.

Application-based Smart Parking System using CAN Bus

“…CAN networks are useful in applications where there is need for small amounts of data to be shared over a network at regular intervals used very similarly in a Smart Parking System as in [10]. The protocol [9], which means that it is a carrier-sense, multiple-access protocol with collision detection and implementation of message priority using bit-wise arbitration.…”
