Research On The Integration Design Of Large Industrial Real-Time Communication Gateway

This paper focuses on the integration of large-scale industrial real-time communication gateways,and optimizes the design from the programming of the main control module,routing module software,task scheduling with different priorities,task readiness table,tsrr scheduling algorithm improvement,ared algorithm improvement and cwared algorithm improvement,and simulates the design results.The experimental results show that:(1)through the analysis and comparison of the response time results of multi priority task operation system,it can be seen that the response time of ucos-iii operating system for multi task scheduling and switching is shorter than that of u COS-II system,and with the increase of the number of multi priority tasks,the response time gap is more obvious.In addition,in the process of multi priority task switching,the maximum response time is the task scheduling switching with the longest delay time.From the figure,it can be found that the average response time and the maximum response time of the improved ucos-iii system are closer,indicating that the real-time response performance of the ucos-iii system is more stable.It can be seen that the real-time response ability of the signal can be improved by using ucos-iii system in the gateway main control module for task management and task scheduling.(2)from the CPU utilization ratio of the number of multi ready tasks under the same priority,it can be seen that for the same number of tasks in the time-sharing system,the improved tsrr algorithm consumes less CPU overhead,that is,the system has more memory left and the algorithm has better processing performance,which verifies that the improved tsrr scheduling algorithm can improve the CPU utilization efficiency and task scheduling to a certain extent Real time.(3)comparing the two algorithms in the simulation time,we can see that the average delay of cwared algorithm fluctuates up and down in 85 ms,while that of rio-c algorithm fluctuates up and down in 90 ms,which shows that the improved cwared algorithm is better than rio-c algorithm in controlling network congestion.(4)when the weighted WQ is determined by multiple parameters of classification service,the fluctuation range of the average queue length is smaller,so the better decision of packet dropping is guaranteed,the probability of global synchronization is effectively reduced,the adaptability to link congestion is better,and the data transmission is more stable.
