Today, the use of wireless technology is growing, have a lot of advantages compared to wired technology. Cost-effective solutions can be developed with this technology and exploited the portability. The wireless transmission can be used in order to expanding an existing wired system in cost effective and easy way. The Thesis topic is linked to this. The aim was design a unit which can transmit messages between the CAN bus and the wireless channel. At the wireless data transmission a custom protocol was developed.
The first chapter introduces the CAN bus and wireless communication as a theoretical basis, describes the hardware implementation options. The chapter exhibits a few known wireless hardware unit and the general properties summary. The second chapter describes the 433MHz and 2.4GHz system design. The chapter explains why it's worth to achieve a common module. The chapter ends in the aggregate system block diagram and the tasks, functions for each hardware block.
The third chapter describes the detailed structure of the system, an overview of the hardware components. The chapter describes the microcontroller program and the computer software environment construction and operation.
The fourth chapter contains instructions for the module, describes the necessary pre-requirements for using the system and the steps of the installation and the operation.
The Thesis’s Appendix presents an application of the system and presents opportunities for further development of the system.
