Abstract

A conveyor transports baggage toward an inspection unit. The inspection unit inspects the baggage transported by the conveyor on the transport path. A displaceable member is located on the entrance of the inspection unit. When the baggage comes into contact with the displaceable member, the displaceable member is displaced. A sensor detects the displacement of the displaceable member. Therefore, before the baggage reaches the inspection unit, it is judged whether the size and shape of the baggage can be inspected by the inspection unit.

Abstract

The present invention relates to a train control device. The train control device sets an emergency brake pattern and a regular brake pattern as patterns of maximum speed according to the distance to a stopping point, and outputs a braking command when the train speed exceeds the maximum speed. Then, when the maximum speed defined in the regular brake pattern falls below a set speed, the maximum speed of the regular brake pattern is kept constant for a predetermined distance. After that, the maximum speed is gradually reduced toward a stopping point of the emergency brake pattern. This allows a train to make an approach to a fixed stopping position in an automatic train operation even when the fixed stopping position is located farther than a stopping point of the regular brake pattern, and excessive output of an emergency braking command based on the emergency brake pattern can be reduced.

Abstract

The present invention pertains to a train control device. This train control device sets an emergency braking pattern and a normal braking pattern, as patterns for maximum speed corresponding to the distance to a stopping point, and outputs a braking command if the speed of a train exceeds the maximum speed. If the maximum speed stipulated by the normal braking pattern decreases to a set speed, the train control device holds the maximum speed for the normal braking pattern constant for a prescribed distance, and then gradually reduces the maximum speed as the train approaches the stopping point for the emergency braking pattern. As a result, entry of a train by a fixed point train stop position can be achieved, and excessive output of emergency braking commands by the emergency braking pattern can be suppressed, even if the fixed point train stop position during automatic train operation is more distant than the stopping point for the normal braking pattern.

Abstract

Shuttle operation of a train at a terminal station is performed unpiloted, without a driver boarding the train. A signal that causes a train (12a) to move back to a common passing track (22) is sent to the train (12a) which is on an arrival platform track (22). After the moving back operation has been completed, a signal for switching a front driver's cab (14) between the front and back of the train is sent to a train (12b) on the common passing track (24), and after the switching operation has been completed a signal that causes the train (12b) to move forward towards the departure platform track (26) is sent. The shuttle control corresponding to these signals is executed by an on-board device (16). The execution of the shuttle control is permitted on the condition that a shuttle commencement confirmation from the driver has been detected.

Abstract

An object of the present invention is to accurately perform the switching of control rights with respect to a train that passes a control section boundary and contribute to the safe operation of the train. A first ground device that is installed in a first section of a train traveling path and a second ground device that is installed in a second section which continues in a train traveling direction with respect to the first section are installed. When the train enters a control transfer section whose terminal end is determined to be the control section boundary of the first section, the first ground device instructs a first on-vehicle radio to transmit a first report signal to the first ground device according to a first communication condition, and instructs a second on-vehicle radio to transmit a second report signal to the second ground device according to a second communication condition. The second ground device, in response to the second report signal that is accepted from the second on-vehicle radio, instructs the second on-vehicle radio to transmit a report signal that contains train position information to the second ground device according to the second communication condition.

Abstract

Mobile radio devices are disposed at the front and rear ends of a mobile body in such a manner that the mobile radio devices can communicate. At least one of fixed radio devices is used as a synchronization base station. The other radio devices including the mobile radio devices are used as synchronization packet relay stations. Each relay station, when powered up, transitions to a synchronization acquiring mode in which a reception of a synchronization packet is awaited. When having received the synchronization packet without intervention of the mobile radio devices, each relay station transitions to an on-ground synchronization maintaining mode, which indicates a high level of synchronization precision, and becomes able to transmit the synchronization packet. When having received the synchronization packet with the intervention of the mobile radio devices, each relay station transitions to an on-vehicle synchronization maintaining mode, which indicates a lower level of synchronization precision than the on-ground synchronization maintaining mode, and becomes able to transmit the synchronization packet. When having received the synchronization packet from another relay station that is in the on-ground synchronization maintaining mode, each relay station that is in the on-vehicle synchronization maintaining mode transitions to the on-ground synchronization maintaining mode.
