Abstract: At present, the fixed time operation mode is adopted during the job scheduling of tunnel cleaning robot. This would waste the power and the fire resources and affect the driving safety. Aiming at this problem, an intelligent scheduling method of tunnel cleaning robot is presented. Firstly, the time varying operation character of tunnel infrastructure is described according to the influence factors, such as traffic flow, temperature, humidity and so on. Then, considering the operation performance of infrastructure, the operation cost of robot, the impact on tunnel traffic flow and so on, the cascading optimization scheduling model of tunnel cleaning robot is constructed. The scheduling cycle and operation time of cleaning robot are optimized respectively to realize the efficient operation of robot. In the experiment, the proposed method is compared with the commonly used fixed time scheduling method. The results show that at the same operation cost, the infrastructure operation performance increases 6% by using the proposed method compared to the fixed time scheduling method.
