Abstract: In order to optimise communication window chip and solve the real-time problem in the industrial wireless networked control, the optimal scheduling algorithm based on throughput maximisation of non-periodic information (TMN-Scheduling Algorithm) is proposed and proved. Compared with typical application layer scheduling strategy of industrial internet of things, it improves non-periodic tasks theoretical throughput. At the same time the solution method of scheduling timetable based on non-linear programming model is given for the scheduling algorithm. Finally, the simulation shows that the scheduling algorithm is not only effective in reducing timeout problems of the periodic communication task, but also improves the theory throughput of non-periodic task.
