BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a route control system and an electronic obstacle avoidance control system,

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-board career control system and method for inter-stationary electron occlusion system for low-depth urban railway, and more particularly, It can be applied to the section of train with less than one train between the station and the station, such as the light rail line, and it is possible to construct a train control system at low cost through electron occlusion system and in- Way career control system and method therefor.

To prevent the collision between the preceding train and the next train in the existing main railway and urban railway, the position information of the preceding train is detected by the next train and the braking control is performed. The train position detection method using the current track circuit is to detect the position of the train by installing a track circuit every 200m in the urban railway section and to show the speed limit to the next train operator through the signal display of the interlocking device and the ground signal, Automatic Train Stop) to stop the over-train. Therefore, a lot of ground equipment is installed on the side of the track, which requires huge construction cost and complicated maintenance work.

Interlocking system for train control of the train at the branch of the railway station, automatic train operation (ATO) at each station should be installed in the station of signal equipment in the station. Therefore, it requires enormous construction cost, operating cost, and reverse function room.

In the new concept of low-depth urban railway, which intends to construct underground light railway with the construction cost of the light rail at the recent high price, it is necessary to integrate the signal equipment room, which exists in each station, into 3-4 units, In this paper, we propose an on - board career control system for an electron occlusion system between urban railway stations.

As shown in FIG. 1, the conventional railway signal control system is composed of a railway centralized control device, a linkage device of a reverse signaling machine room, a track circuit, a signaling device, a line switching device and a vehicle signaling device, (CTC) to monitor the position of the train and the position information of the train to the train, and to transfer the line switching control command to the field facility so as to switch the branch in the traveling direction of the train, It informs the driving engineer through a signal.

As shown in FIG. 2, the train spacing control is performed by an automatic closing device when the preceding train occupies the track circuit (main railway 600 m, urban railway 200 m) of the rail separated by the fixed closure method using the track circuit and the signaling device The line signaler changes to stop, caution, and progress signal to provide the speed limit information to the following train.

In addition, for automatic train operation, an automatic train operation device should be installed for stationary stop in train, train start control, and acceleration / deceleration control. The configuration of such an automatic train operation unit (ATO) is composed of an on-train ATO facility of a train and a ground ATO facility installed in each station.
