Conventionally, when trying to achieve unmanned train operation and labor saving at the depot at the same time, it was necessary to start receiving power before the train leaves the detention track, stop receiving power after the train enters the detention track,
In other words, there is no way for drivers, maintenance personnel, etc. to connect and disconnect current collectors such as pantographs and overhead wires without getting on the train or getting close to the train, which hinders unmanned operation and labor-saving efforts. was.

Therefore, the purpose of the present invention is to automatically and centrally control the start of power reception before the train leaves the depot and the stop of power reception after the train enters the depot using commands from the control center on the ground side. To provide a stop control device.

The features of this invention are, in order to achieve the above objectives,
means for receiving a command signal sent from a control center on the ground side via antennas on the ground side and above the train, and determining whether it is a command signal for the own train and whether it is a command to start receiving power or a command to stop receiving power; An opening/closing switch whose opening/closing is controlled by this discrimination means, a current collector controller which drives a current collector such as a pantograph according to the opening/closing of this opening/closing switch, and a current collector controller which detects the completion of operation of this current collector and controls the antenna. A transmitter that sends an operation completion signal to the ground side via the switch, and a transmitter that opens and closes in response to the opening and closing of the on-off switch to supply power to at least the transmitter after power reception has stopped and the current collector controller before power reception has started. The structure is such that a storage battery is installed for each train.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a top view showing an example of a vehicle depot.
In Fig. 1, 1 is a ground equipment installed in a control center on the ground side, 2a, 2b, 2c, ..., 2n (hereinafter collectively referred to as 2) are ground side antennas, 3a, 3b, 3
c,..., 3n (hereinafter collectively referred to as 3) indicate retention lines. The ground side antenna 2 is provided for each detention line 3, and each ground side antenna 2 is connected to the ground equipment 1 in parallel.

FIG. 2 is a diagram showing the state of the train 6 stopped at the detention track 3. When the train 6 stops at a stop position determined by conditions such as track structure, the on-board antenna 3' and the ground-side antenna 2 corresponding to the parking line are connected.
and are facing each other at the shortest distance (approximately 10 to 30 cm). Reference numeral 4 indicates an on-board device connected to the above-vehicle antenna 3', and 5 indicates a pantograph (hereinafter, a general pantograph will be referred to as a current collector).

FIG. 3 shows a configuration diagram of an embodiment of the ground equipment and the on-board equipment. The ground device 1 includes an operation console 13 and a communication control device 12. The command signal generated by the operation console 13 is transmitted to the communication control device 12 and the ground side antenna 2.
The signal is transmitted to the antenna 3' above the vehicle.
The command signal received from the on-board antenna 3' is input to the receiver 7 in the on-board device 4, where it is determined whether it is a command signal for the own train or not, and whether it is a command to start receiving power or a command to stop receiving power. A control signal to open or close the open/close switch 9 is output.
For example, in the case of power reception start control before the train leaves the detention track, a "close" control signal is output to the on/off switch 9, and as a result, power is supplied from the storage battery 8 to the pantograph controller 10, and the pantograph The controller 10 drives the pantograph 5 upward and connects the pantograph 5 to an overhead wire (not shown). When the rising movement of pantograph 5 is completed,
That is, when it becomes possible to start receiving power, the transmitter 11 sends a lift completion signal to the console 13 via the on-board antenna 3', the ground antenna 2, and the communication control device 12.
On the other hand, in the case of power reception stop control after a train enters a detention track, after the train has stopped in a fixed position, the method described in Japanese Patent Publication No. 1983-4083 "Vehicle Operation Control Method" by the same applicant as the present application is applied. The pantograph controller 10 uses the fixed position stop completion signal as a trigger to control the pantograph 5.
is lowered, and a descent completion signal is sent from the transmitter 11 to the console 13. After that, by operating the console, an "open" command is sent to the open/close switch 9, and the storage battery 8 is
to open. Note that the storage battery 8 is the pantograph 5.
It is a rechargeable storage battery while receiving power.

FIG. 4 is a diagram showing one embodiment of the receiver 7.
In FIG. 4, 14 is a detector, 15 is a smoothing circuit, 16 and 17 are resonant circuits having different resonance frequencies, and 18 is a gate circuit. Car top side antenna 3'
The command signal is input to the detector 14 to detect the command signal. Most of the detection output is from the smoothing circuit 1
5 and sent to the gate circuit 18.
On the other hand, the detection output is also input to two resonance circuits 16 and 17 in parallel. Resonant circuit 16 or 17
When the circuit resonates, the output signal causes the gate circuit 1 to
Perform the gate operation in step 8. For example, the resonant circuit 16
When resonance occurs, the gate circuit 18 outputs a control signal P _po that closes the open/close switch 9 (not shown in FIG. 4). Furthermore, when the resonant circuit 17 resonates, the gate circuit 18 outputs a control signal P _pff that turns the open/close switch 9 "open".

FIG. 5 shows an example of a specific circuit diagram of the receiver 7. In FIG. 5, 19 and 20 are AND circuits, and these 19 and 20 form a gate circuit 18. The detector 14 consists of a circuit in which an inductance L ₁ coupled to the inductance of the antenna 3' above the vehicle, a variable capacitor C ₁ , a capacitor C ₂ , a diode D, and a resistor R are connected as shown in the figure, and the smoothing circuit 15 includes a capacitor C ₃ , _C4 and an inductance _L3 as circuit elements, and the resonant circuits 16 and 17 are inductances.
It consists of a circuit in which inductances _{L 3 and} L ₄ coupled to L 3 and capacitors C ₅ and C ₆ are connected as shown. As is clear from FIG. 5, the receiver 7 does not require a power source and is configured to operate only on received power. It should be noted that the transmission power required on the ground side to operate the receiver 7 is sufficient to be 5 to 7 ampere turns in terms of magnetizing power.

FIG. 6 is an example diagram of the operation console 13. The operation console 13 has a detention line number 21, a train number display 22,
an indicator 23 indicating the “closed” state of the open/close switch 9;
It consists of an indicator 24 that indicates the stop of the train and the completion of lowering of the pantograph, and a switch 25 that generates an open/close signal for the open/close switch 9. The detention line number 21 is fixed. The train number display 22 displays the number of the train on the detention track, and is displayed from the time the train enters the warehouse until the time the train leaves the warehouse. The train number is detected and displayed by another means near the entrance of the depot when entering the depot, and the display is similarly turned off when leaving the depot. The display 23 indicating the "closed" state of the open/close switch 9 indicates the power reception start signal from the pantograph described above. The indicator 24 is an indicator indicating that the pantograph has completed its descent and at the same time indicates that the opening/closing switch 9 should be opened. The switch 25 is a switch that instructs the train to start receiving power and stop receiving power.

FIG. 7 is a block diagram showing another embodiment of the ground equipment 1, in which a command signal is generated without using the console 13. In Figure 7, 12 is the third
26 is a terminal device and 27 is a computer having the same functions as the communication control device shown in the figure. The electronic computer 27 stores the departure time and arrival time of trains, and instructs the trains in the depot to start receiving power and stop receiving power according to the sequence. The terminal device 26 connected to the computer 27 functions as an interface between the computer 27 and the communication control device 12, and also allows an operator to directly intervene and control the communication control device 12 in the event of a failure of the computer 27. It is equipped with a control panel.

As explained above, according to the present invention, when a train enters or exits a warehouse, the operator can stop or start receiving power by commands from a distant ground-side control center, without the operator getting on the train or approaching the train. Automatic control will be possible, making it possible to make trains unmanned and save labor.
