Car parking guidance application using controller area network

Abstract

The large number of new vehicles is increasing everyday. So the parking system becomes an important component of the transportation system. Parking is inadequate in many countries. In Vietnam, Car parking is a big problem in many cities such as Hanoi, Hochiminh City… So the development of the car parking is required. In the range of this project, I built an application to guiding car to get a slot when it enters a car parking. This apllication was based on Controller Area Network (CAN). The Controller Area Network (CAN) is a serial communications protocol suited

for networking sensors, actuators, and other nodes in real time systems. In this section, we first give a general description of CAN including its message formats, principle of bus arbitration, and error-handling mechanisms.Extensions of CAN, such as application-

oriented higher-layer protocols and time-triggered CAN, are described, followed by a brief history of CAN. By using PIC microcontrollers (PIC18f4580), CAN controller (MCP 2551) and detection Sensors in market, this project aims to build a system to detect accurate and reliable the number of vehicles available in a parking lot. My work is to build four circuits that can connect with each other through CAN network.
