Design and Implementation of Net Communication Protocol For Front-End Device in Distributed Testing and Controlling System

摘要

Net communication protocol for front-end device based on CAN bus is designed for distributed testing and controlling system. There are three basic features in the protocol: large data block is transferred efficiently in a producer/consumer model; high reliability and real time control between the main device and front-end device is achieved through the point-to-point communicate model, dynamic insertion and removal of a device is also achieved. This protocol has been applied in practice. Because of low cost, high reliability and easy to be implemented, the protocol can be used wildly relative fields.
