As an indispensable part of comprehensive urban transportation,the rail transit system is in urgent need of more advanced modes of transportation and automated management in the face of increasing urban population pressure and traffic demand.Metro and public transportation are the main ways for people to travel in cities,which provides great convenience for pedestrians.In a small area with large population density,the road traffic resources are tight,the subway system can't be reached,and people can only walk.Based on this situation,this paper proposes shallow rail transit and shallow rail transit control system based on granular function control principle.To improve the difficulty of small-scale short-distance travel.The shallow rail transit is located in the shallow layer below the ground.The top of the shallow trench covers the transparent glass roof,and the small rail train runs in the shallow trench,and at the same time considers the construction difficulty,construction time,underground pipeline,energy saving and emission reduction and operation structure.Shallow rail transit uses a shallow rail transit control system based on the principle of granular function control.This system can not only automatically control the train operation,but also under the premise of ensuring the safe operation of the train,the performance of the punctuality and comfort of the train operation can be improved,and the energy saving effect is good.The train operation has the characteristics of nonlinearity,multi-objectiveness and complexity.It is difficult to establish accurate mathematical models and optimal solutions.It is difficult to achieve satisfactory control effects by conventional algorithms.The granular function control principle proposed in this paper adopts the combination of fuzzy control and point function.The fuzzy control can reflect the control idea well,meet the high-quality operation of the train,and realize the simple realization of the point function control.The combination of the twomethods can solve the complicated control problem.The shallow rail transit control system based on the granular function control principle proposed in this paper not only enriches the control theory based on the granular function,but also realizes the high quality control of train operation.In the analysis of the train from the stationary to the starting state,to the idle state,to the braking state caused by the speed limit,the acceleration state of the speed limit release,and the final parking state,the control principle based on the particle function is applied to the shallow layer.The steering strategy of the automatic driving of the rail train.The simulation results show that the shallow rail transit control system based on the granular function control principle can achieve the punctuality,comfort,parking accuracy and punctuality of the train.The system can achieve the expected control effect.
