Design of an alarm system with CANBUS

With the development of industrial technologies, particular communication protocols have been developed. Controller Area Network (CAN) is one of the important communication protocols. It is an effective and sufficient protocol used in variety of industrial applications. Synchronous systems need three wires for serial communication, whereas asynchronous communication systems can serially communicate through two wires. Because of having an asynchronous communication structure CAN protocol systems only need two wires, and this is an advantage from the cost and complexity points of view. Since the CAN protocol have event oriented structure can not be used for controlling real-time systems. To solve such problems time triggered CAN (TT-CAN) has been developed, and are described in the thesis.In this thesis, first of all CAN applications were extensively discussed. The CAN protocol infrastructure, message transmission, error detection, baud rate calculation and appropriate IC selection for the system were also discussed. In the fourth part 18F458 micro controller CAN module and its registers were analyzed. In the final part of thesis, as an application, an alarm system and an analog to digital converter were designed and realized with CAN protocol. The results and practical considerations were discussed in this section. The designed circuit schemes for two node bidirectional communication with CAN protocol and soft codes were given in appendixes.KEYWORDS: CAN, LIN, TTCAN, TTP/C, FlexRay, Real Time Applications, Alarm Systems, PIC18F458, 82C250, MCP2551
