摘要： PURPOSE: To improve a fixed position stopping accuracy by preventing a driving force from fluctuating when stopping a traveling body (train). CONSTITUTION: Position information θ corresponding to a vehicle position 1 and an actual phase θ is set to a phase setting part 4 in advance and the stored position information θ' is successively outputted from this side of a target stop position when controlling stop. An adder 5 adds the phase information θ' and the actual phase θ and outputs an operation phase θ". A multiplier 6 multiplies a current command value Ip by the operation phase θ" and a power converter outputs a current pattern to be conducted to an armature.

摘要： PURPOSE:To improve the accuracy of stop by installing magnets on a track and by utilizing attracting force and repelling force as a driving force to the fixed stop point which is created between the magnets and superconductive magnets on a car. CONSTITUTION:Two electromagnets 3 for fixed point stop are installed on a track 1 in the order of N-pole and S-pole on the left side of the traveling direction of a vehicle 2 and also two other electromagnets in the order of S-pole and N-pole on the right side, and the electromagnets 3 are electrified when the vehicle 2 travels and the reference position A on the vehicle comes to the position C which is located at a distance of one pole pitch from the fixed stop point B to the approaching vehicle. Then, the direction of thrust due to the magnetic forces between the electromagnets 3 and the superconductive magnets on the vehicle becomes the same as the traveling direction of the vehicle 2 and, when the vehicle reaches the fixed stop point, the thrust becomes zero. After passing fixed stop point B, the direction of the thrust becomes reverse to the traveling direction of the vehicle 2. By doing this, the thrust which always directs the reference position A of the vehicle at the fixed stop point B can be obtained.

摘要： PURPOSE:To avoid the increase in number of number detection circuits even when number of mobile bodies is increased by giving a code read timing mark and other mark to a mobile body as an identification code through combination. CONSTITUTION:A data is fetched to a buffer 12 and whether a mobile body is running in a direction A or B depending on the start and end of the fetched data is discriminated. When timing marks 71-7h, number marks 8a-8d, and start and end marks 9a-9b are detected, the number of the mobile body running in the direction A is detected according to the fetched order of data. When the timing mark 7h and the end/start mark 9b are detected and the number mark 8 is not detected, the moving direction is discriminated to be B, the input data of the number mark is inverted to detect the number of the mobile body. When a computer 15 recognized the number of the mobile body, it is compared with a destination given to the number of the mobile body in advance and a truck branching device is controlled for the operating command.

摘要： PURPOSE: To control the speed and to detect the position of a carriage train by power supply trolley wires and a signal trolley wire by providing detecting means for detecting the polarity of a power supply line in the train.
CONSTITUTION: When a carriage train 9 moves to a signal trolley 9e, a current flows to a photocoupler 29e for detecting the position of the train, and the signal is input to a carriage train service controller 26. If a forward electromagnetic contactor 33e is closed at this time, a current flows to a forward signal receiving photocoupler 20, and a forward command is input to a speed controller 13. On the other hand, if a low speed command switch 27e is closed, a current flowed to the trolley 6e is cut off. Accordingly a low speed command receiving photocoupler 22 becomes OFF, and a slow speed command is input to the controller 13. If the contactor 33e is opened, the power of a power supply trolley wire 4 is interrupted, and an electromagnetic brake is operated to stop the train 9.
