The Studies And Applications Of Communication Technologies For Embedded Control System

To promote the development of industrial technology in the control system for wider application. With the control system function continues to increase, the system becomes more and more complicated, inevitable in the large, decentralized development, resulting in communication technology in the control system used extensively. At the same time, computer technology-based embedded systems also have strong and took control of their own characteristics in the field play an important role in the communication control system based on the large task of embedded system implementation. The existing control system of communication modes can be divided into the incident triggered manner and timing trigger mode. But whether that trigger mode has its inherent limitations, the use of any single approach can trigger a very good communication control system to meet the requirements.This paper communications to embedded control system optimization as the starting point, to improve the communication needs of a real-time communication network flexibility, real-time to meet the demand of transmission for the end result. In-depth analysis and summary time-triggered communication with the incident triggered on the basis of the characteristics, and the proposed time-triggered events will trigger combined to optimize communication or control system based on the thinking of the formation of a new communications system. Portfolio trigger mode can trigger very good way to solve time poor flexibility, real-time incident triggered poor way inadequate, but can also meet the needs of transmission. This paper presents a combination of the two methods - Static and dynamic binding combination of law. Against dynamic combination of law, the implementation process is given by the measured validity of the method used to realize. Static binding law in the analysis and implementation process in order to optimize the existing Ethernet for the purpose of achieving a fully compatible with the Ethernet-based 802.3, and the simulation experiments, the certification of the relevant properties. In addition, the paper also combining static and dynamic binding method applicable network queuing delay ceiling were analyzed.
