The ATO(Automatic Train Operation) System is used for train operation instead of drivers. It is interfaced with TCMS(Train Control and Monitoring System) and ATC/TWC system in the train and wayside facilities. In this paper describes configuration of ATO, specification of ATO hardware, construction of ATO software and the algorithm fur automatic train speed regulation in the carborn ATO system. ATO Application Software is consist of ART, SPR, REG, SRV and PSM tasks. ART task is main control part of the ATO that determine ATO control, ATO mode, state transition. SPR determine speed reference according to train motion status, track data, train data and restricted train speed. REG task regulated train speed form the starting of one station to the precision stop at the other station under the result of ART and SPR tasks. In this paper, a algorithm for the train speed regulation while running is described.

무인운전 경전철 운전계획을 위해 수동운전 기반의 TPS(Train Performance Simulation) 대신에 ATO(Automatic Train Operation) 자동운전에 기반한 TPS가 요구된다. 본 논문은 ATO 패턴을 사용하는 새로운 TPS 모델을 제시하고, 서울지하철 6호선의 시험구간과 부산-김해 경전철 전체 노선의 실제 자동운전 운행결과와 시뮬레이션 결과를 비교하였다. 실제와 유사한 ATO 운행패턴은 상용감속도, 저크, 역정차감속도, 구배환산거리의 4가지 파라미터를 도입한 새로운 TPS 모델에 의하여 매우 정밀하게 시뮬레이션 될 수 있다. 무인 자동운전을 위한 상업운전용 표정시분은 ATO기반 TPS의 "Fast" 운전모드 운행시간에 경전철 표준사양에 따라 km당 3초의 여유를 가지도록 본 논문에서 제시된다.

The automatic-driverless operation, a very important technique for metro railways, is necessary for achieving higher safety, greater reliability, and bigger transport capacity. To achieve these things, we have to build up the system design and tasting techniques for the railway system operation. These techniques are related to the onboard train control and communication systems which include TCMS(Train Control and Monitoring System), ATO(automatic train Operation), ATC(Automatic train Control), and TWC(Train to wayside communication). These sub-systems should interface not only with each other but also between the sub-systems and the signal system on the ground. For the saving of energy, we designed coasting strategy of ATO system, In this paper, we developed ATO system and tested on the test line and ...

This paper describes the calculation and application of the speed profile for the train speed control when the train is operated by ATO(Automatic Train Operation). We propose a speed profile calculation method considering the speed limitation and the jerk limitation, in order to maintain the quality of the train automatic operation. In previous works, ATO calculates a desired speed profile along the time, and controls the train to follow the profile. In this case, it may be hard to follow the restrictive speed along the location or to stop the train with a low location error, because of the difference between the desired location at each time and the real location of the train due to the control error. In the proposed method in this paper, we calculate a desired speed profile along the time considering the speed and jerk limitation first, and derive a speed profile along the location using it. If the restrictive speed profile is changed or the train speed strayed from the speed profile, ATO system calculates new speed profile and applies it immediately. Because ATO system controls the train speed based on the train location, the accuracy of the train location control can be improved. A simulation system for the test of the automatic train operation using this method is designed.

The automatic/driverless operation which are great important techniques in metro railway are required to increase higher safety, greater reliability, and transport capacity. To satisfy such demands, we must have the system design and testing technique for the railway system operation. These techniques are related to the onboard train control and communication systems which include TCMS(Train Control and Monitoring System), ATO(Automatic Train Operation), ATC(Automatic Train Control), and TWC(Train to Wayside Communication). These sub-systems must be interfacing with not only each others but also the signal system on the ground. We tested the train control system on Test line that has been developed on the basis of the standardized type EMU for korea railway systems. This test line which is located in Sangju, have been constructed for testing 7 ＆ 8 line of Seoul Metro railway.

5678SMRT (Seoul Metropolitan Rapid Transit Co) by a ATC/ATO system the other side which is operated with an automatic movement with a manual operation, the Seoul subway 1.2 lines ATS and 3.4 lines adopt a ATC method and they are operated. But it is improving progressively in SMRT railway ATO method. The ATO the operation method leads exchange of information of wayside and train system for and it is possible, the TWC system configuration is becoming wayside and train system and the radio antenna. It discussed the equipment for a TWC system and a automatic operation from the dissertation which it sees. It investigated a data exchange, a message format and an interface control method and it joined in and a system maintenance conservative method it discussed.

An automatic operation of train is executed by an automatic train operation(ATO) system. The main function of ATO system is to control train speed. So it makes the train stop at the programmed position accurately and improve riding comfort. In this paper, A fuzzy control is designed for speed control. The simulation is executed for verifying the speed control performance of the fuzzy system and comparing with that of the conventional PI.
