基于CAN总线通信协议安全及汽车温度检测系统的研究

摘要

In order to achieve real-time detection of secure communications and automotive temperature inside the car CAN node, we use microcontrollers and CAN bus design a car temperature detection system. The system is based on CAN bus communication protocol to implement safety check at each node to communicate with each other, and real-time detection of various parts of the body temperature. The experiment shows that the system in real-time safety and a significant increase, but also has good portability, convenient secondary development.%为了实现对汽车内CAN节点的安全通信和汽车温度的实时检测，本文采用单片机和CAN总线设计出一套汽车温度检测系统。该系统基于CAN总线通信协议，实现对各个节点相互通信时的安全校验，并能实时检测车身各个部分温度。经实验表明，该系统在安全性和实时性具有显著的提高，同时具有很好的可移植性，方便二次开发。
