Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a traveling control method for an electric vehicle.

[Technical background of the invention]

First, the ground control method which is the object of the present invention will be described. FIG. 1 shows a conventional electric vehicle control method.

Direct current or alternating current with a constant voltage is supplied from the substation 1 to the electric line 2. The electric car 6 uses this electric power as a collector or a ground wheel 3,
Incorporate into electric car 6 through 7. The electric vehicle 6 includes a main motor 5 and a control device 4 that controls the speed of the vehicle by controlling the voltage and current supplied to the main motor 5. First, a driver's instruction is given to the control device 4 to control the speed of the electric vehicle 6. In addition to these, there are various electric devices such as auxiliary machines, but they are omitted and not shown in this figure.

This method has an advantage that a plurality of electric vehicles can be put into one substation section, and that it is sufficient to always supply electric power of a constant voltage from the substation, which makes the substation simple. However, it is necessary to mount a control device for controlling the main motor on the vehicle. The on-vehicle control device requires sophisticated functions to control electric power, and is large in volume and weight. As an example, in the case of an ordinary electric vehicle (electric vehicle) or a monorail, the control device and its related devices account for 10 to 20% of the weight of the empty vehicle. In other words, this dead load is always being transported, which is a large loss in terms of power consumption during traveling.

On the other hand, in the case of a monorail, the wheel load of a tire is extremely severely limited.When the passengers are full, this limit will be exceeded, so more seats will be added to intentionally block the area, The equipment room is provided to prevent passengers from getting in when the vehicle is full, and this strict load limitation is being observed.

Also, in terms of equipment loading volume, in the case of monorail, especially in the method of holding the track under the floor (straddle type), the effective loading volume is given to the track, so the effective loading underfloor volume for loading this control device is obtained. Therefore, there are cases where the vehicle width must be widened. This is a major obstacle because it does not match the width of the vehicle body, the width of multiple tracks, and the width required from the fire-fighting space, etc. when this vehicle is put into a narrow passage such as an 18-m-long passage as in recent urban traffic. .

In terms of construction cost, recent transportation systems are often constructed on roads, in which case they will be elevated. In this case, the vehicle running on it should be light in order to reduce the construction cost of the elevated structure, which is close to 60% of this elevated system. In addition, in the case of the above-mentioned straddle type monorail, if the vehicle width is narrowed to make a vehicle with a long vehicle length, the interval between the load points of the live load on the girder can be widened. Since it can be reduced, the span of the girder can be lengthened and the number of girder columns can be reduced as a whole. Since the girder columns are piled on the foundation depending on the strength of the ground, reducing this number, especially when constructing a route on weak ground, greatly contributes to the reduction of track construction costs.

Next, considering the operating costs of maintaining and operating such a transportation system, the equipment on the vehicle is always better than the equipment on the ground for keeping the vehicle in a bad environment such as vibration and wind and rain. It costs a lot of money to maintain the vehicle, and because the vehicle is suspended during the necessary maintenance period for maintaining the vehicle, it reduces the efficiency of use and considers the maintenance period for the spare vehicle considering the vehicle failure rate. A spare car will be needed.

The ground control method is a vehicle control method that is effective in improving the problems of these conventional methods and constructing a transportation system with low construction and maintenance costs required in the future. FIG. 2 shows an embodiment of the ground control method. This presents a circuit corresponding to the basic feeding basic circuit shown in FIG. Electric lines 23X and 23Y fixed to the ground and insulation 2
7X and 27Y are provided and divided into certain sections, and the electric lines 23X and 23Y
Substations 1A and 1B corresponding to each section of Y and information transmission line 30
Are provided respectively. In this case, the insulating portion 27Y can be omitted when one of the electric lines, for example, 23Y is used at the ground potential.

The electric vehicle 6A is equipped with a collector or ground wheels 3A, 7A, a main motor and equipment 25 required for its protection and circuit switching, and the speed control part of the main motor is moved to substations 1A, 1B on the ground. . Auxiliary equipment circuits are required in addition to these main circuits. This is done by separately arranging a train line or the like to collect current, but this is omitted and not shown in this figure.

The command of the driver who gets on the 6A vehicle is the substation from the master controller through the information transmission device 28, the onboard antenna 29, and the information transmission path 30.
Passed to 1A. In the substation 1A, the voltage and the current supplied to the vehicle are supplied to the overhead wire in accordance with this command to control the overhead line. By using this method, it is possible to perform the same operation as when the speed control section is arranged on the vehicle even though the speed control section on the vehicle is removed. Therefore, the above advantages can be obtained. Further, since the speed control unit is placed on the ground, it is not necessary to consider the vibration of the vehicle and the size limitation and weight limitation for mounting on the vehicle, so that the device can be extremely reliable. .

[Problems of background technology]

However, in the above-mentioned ground control method, in order to operate and control one electric vehicle in one block section in principle, the electric vehicle is moved from the block section where the electric vehicle is currently present to the next block section. When traveling, it is different from the conventional railway system in that the train can be started only after the substation power supply switching control is performed so that power is inevitably received from the substation in the next block section. Therefore, it is conceivable that an on-board crew member may give a command to the ground side by operating a switch every time the substation feed switching request command, which is not available in the conventional railway, travels to the next closed section. However, in this method, since the crew handles the command from the vehicle to the ground, if the crew mistakenly operates the switch, it may hinder the safe and stable running of the electric vehicle. Become.

[Object of the Invention]

The present invention has been made to solve the problems as described above, and an object thereof is to reliably and reliably switch power supply to a substation when an electric vehicle travels from one specific block section to the next block section. An object of the present invention is to provide a traveling control method for an electric vehicle that allows the electric vehicle to travel safely and stably.

[Outline of Invention]

In order to achieve the above object, in the present invention, an electric line is laid along a track on which an electric vehicle runs, and the electric line is divided by insulators installed in front of and behind the station. The station between the stations was set as a closed section, and a switch was connected between the electric lines separated by an insulator, a substation was set up in the closed section, and a driving command from the electric car was provided to the electric car. It sends it to the controller of the substation from the on-board transceiver via the ground transceiver installed between the insulators, and the substation supplies electric power via the electric line to control the operation of the electric car and the substation. Each substation's unique number signal is sent to the on-board transceiver via the ground transceiver, and when the stop of the electric car at the station is confirmed and the power supply switching command signal is output, the car Each substation in the front block section and the next block section from the upper transceiver through the ground transceiver Among the controllers of each substation that sent the substation power supply switching request command signal to the controller and received the substation power supply switching request command signal, the controller of the substation in the front closed section is the one before the ground transceiver. The transmission of the number signal unique to the substation in the closed section is stopped, and the controller of the substation in the next closed section controls the ground transceivers provided for the next closed section and the next station from the other electric vehicles. When a driving command is not sent, the switch provided to correspond to the insulator that separates the electric line at the rear of the station where the electric car is located is controlled to open, and the insulator that separates the electric line at the front of the station is opened. By controlling the switch provided correspondingly, the electric line from the station where the electric car exists to the next station is fed from the substation in the next block section, and the next on-board transceiver is blocked. Number signal unique to the substation of the section is transmitted and received by the on-board transceiver Characterized by starting the travel of the electric vehicle and displayed on the display device provided in the electric vehicle.

In addition, the electric vehicle runs from the electric line that is divided by the insulators installed before and after the front station to the next block section, and the carrier signal from the on-board transceiver that indicates the on-line of the electric vehicle is provided in the next block section. It is received by the ground transceiver that was installed, and the carrier signal is no longer received by the ground transceiver that is installed on the electric line that is divided by the insulators installed before and after the front station. When the controller detects it, the controller of the substation in the next block section opens and controls the switch installed corresponding to the insulator that divides the electric line in front of the previous station, and divides the electric line in the rear of the previous station. It is characterized in that the switch provided corresponding to the insulating material is controlled to be closed, and the transmission of the number signal to the ground transceiver from the controller of the substation in the front block section is restarted.

Further, as the power supply changeover command signal, an open signal of a door switch for treating a customer at a station and an operation signal of a substation changeover switch for changing a power supply without opening a door for treating a customer are used. It is characterized by

Example of Invention

An embodiment of the present invention shown in the drawings will be described below.
FIG. 3 shows a configuration example of a traveling control method for an electric vehicle according to the present invention. In the figure, there is one block between a station 1 and a station m, so-called one station, and substations 1l, 1m, ... Are provided for each block.

In the figure, the electric vehicle 6A is now fed from the substation 1l through the electric line 23p and the switch 34p to the main electric machine device 25 from the current collector 7A and travels from the right side to the left side in the figure to arrive at the station l. ing. Then, the information transmission line 30r in the next block section,
When there is no preceding vehicle in 30s, switch 34p is opened and the substation
The power supply from 1l is cut off, and instead, the switch 34q is closed to receive power from the substation 1m and it is possible to travel to the station m.
For this purpose, a means for switching the power supply from the substation 1l to 1m in response to a command from the electric vehicle 6A while the train is stopped at the station 1 is required.

Therefore, in the present invention, as means for switching the power supply of this substation, one is that the speed generator 15 detects that the speed is zero and that the door switch is opened to treat the customer. The substation power supply switching request command is output when the conditions of 1) are satisfied, and the substation switching switch is provided instead of the open signal of the door switch so that the power supply switching request command can be output even when the switch is pressed. , Or 2 which is used for forwarding or trial run that does not require door opening / closing is configured as an OR condition. Note that, here, the signal for opening the door switch and the signal for pressing the substation changeover switch are collectively referred to as a power supply changeover command signal.

Next, the traveling control method will be specifically described with reference to the time chart of FIG.

Now, when the electric vehicle 6A stops at the station 1, the speedometer generator 15 inputs a speed signal of zero and the door switch 10 inputs a door open contact signal to the onboard controller 12, respectively. The on-board controller 12 is the fourth
As shown in the time chart of the figure, only when the above signals are input (50a, 50b), the substation power supply switching request command signal is output to the onboard transceiver 13 (50c). This substation power supply switching request command signal 50c is received from the transmitter T of the onboard transceiver 13 via the onboard antenna 29 via the information transmission path 30q and the receiver R of the ground transceiver 31q (50d). . Then, it is input to the controllers 32l, 32m of both substations 1l, 1m (50e, 50f).
The substation controller 32l which has been controlling until now cuts off the transmission of the ground transceiver 31q to the transmitter T (50g). On the other hand, the substation controller 32m is the information transmission line 30 in the next block section.
If there is no preceding vehicle on r, 30s,
Confirm that the receiver R of r, 31s does not receive the carrier signal transmitted from the on-vehicle transmission / reception. If the carrier signal is not received, switch 34p is closed to open, and switch 3p
Output to interlock device 34l to switch 4q from open to closed (50h). As a result, the substation controller 32m sends the substation number 1m to the transmitter T of the ground transceiver 31q (50
i). This substation number 1m is the information transmission line 3 from the transmitter T.
The signal is received by the receiver R of the onboard transceiver 13 via the onboard antenna 29 via 0q (50j). Then, the receiver R of the on-vehicle transceiver 13 sends the signal to the on-vehicle controller 12 (50
k). As a result, the onboard controller 12 displays the substation number 1m on the display 16 (50l), stops the substation power supply switching request command signal, and switches to carrier signal transmission (50m).

In this way, the fact that the substation has been switched is displayed on the vehicle, the door switch (not shown) is closed, and the driver's command is sent through the above-mentioned route through the substation 1l, substation controller 32l of 1m, 3
When sent to 2 m, only the substation controller 32 m commands the power converter 33 m to supply voltage and current. The converter 33m outputs voltage and current, and is supplied to the main motor device 25 from the current collector 7A via the electric line 23r, the switch 34q, and the electric line 23q, and the electric vehicle 6A runs. Eventually, when the electric vehicle 6A moves from the information transmission path 30q to 30r, the carrier signal transmitted from the transmitter T of the onboard transceiver 13 of the electric vehicle 6A is transmitted from the onboard antenna 29 to the information transmission path 30r.
Then, the signal is received by the receiver R of the ground transceiver 31r (60a).
On the other hand, the receiver R of the ground transceiver 31q does not receive the same signal (60b). Then, the substation controller 32m turns the switch 34p
To switch from open to closed and switch 34q from closed to open by interlock device 34l (60e).
Then, when the switching is completed, the transmission of the ground transceiver 31q from the controller 32m is cut off (60d). At the same time, a transmission permission signal is given to the substation controller 32l through the signal line 35l (60
e). The controller 32l starts transmission (60f).

In this way, the succeeding vehicle at the station in front of the station l can travel to the station l. Indicator 1 of substation No. 1m that is supplied with power
6 is displayed from the substation controller 32m to the on-board antenna 29 from the transmitter T of the ground transceiver 31r via the information transmission path 30r.
Then, the signal is input to the onboard controller 12 via the receiver R of the onboard transceiver 13, and the same number is continuously displayed.

As described above, the electric lines 23p to 23r are laid along the track on which the electric vehicle 6A runs, and the electric lines 23p to 23r are divided into closed sections, and the substations 1l and 1m are divided into the closed sections. The substations 1l and 1m connected to the electric line for the electric car 6A on the track according to the operation command are connected to the electric line 23p to 23r.
In the method for controlling traveling by supplying electric power via the electric vehicle 6A, when the electric vehicle 6A travels from a certain closed section to the next closed section, a detection signal indicating that the electric vehicle 6A is stopped at a station 1 and switching of electric power supply. When the on-board controller 12 inputs both of the command signals, the on-board controller 12 via the information transmission device to the controller 32l, 32m of each substation 1l, 1m of the relevant closed section and the next closed section. Each substation that has transmitted the substation power supply switching request command signal and then received the substation power supply switching request command signal
1l, 1m of the controller 32l, 32m out of transmission from the controller 32l of the substation 1l of the relevant closed section to the on-board controller 12, and through the information transmission device when the substation power supply switching is completed Send the number signal of the substation 1m in the next block section to the on-board controller 12, display the number on the display 16 and start running the electric vehicle 6A according to the operation command, and then the electric vehicle 6A closes the concerned. The carrier signal generated from the on-board transceiver 13 that the vehicle has traveled from the section to the next block section is received by the ground transceiver 31g in the next block section via the information transmission device, and the carrier signal is received by the ground transceiver 31g. When the controller 32m of the substation 1m in the next block section detects that it has stopped, the power supply to the substation 1l in the block section is restored and the controller 32m of the substation 1m in the next block section The controller 3 of the substation 1l that cuts off the transmission to the ground transmitter 31q and is in the closed section It is designed to send a signal to 2l to restore the transmission.

Therefore, in the above-mentioned ground control method, in order to operate and control one electric vehicle in one block section in principle, the electric vehicle 6A travels from the block section where the electric vehicle currently exists to the next block section. This is different from the conventional railway system in that the train cannot be started unless the substation power supply switching control is performed so that power is inevitably received from the substation in the next block section. In the method, each time the substation power supply switching request command is provided to the ground side by operating the switch every time the substation power supply switching request command is traveled to the next closed section, as described above, the electric power is supplied as described above. car
It is given when both the detection signal that 6A is stopped at the station and the substation power supply switching request command signal are satisfied. Therefore, since the power supply switching is performed without directly going through the crew members on the vehicle, the power supply switching when the electric vehicle 6A is traveling from one specific block section to the next block section is accurately performed without error, and the electric vehicle 6A is safe. In addition, it becomes possible to perform stable traveling control. Also, due to the above reasons,
By not confirming the substation power supply switching request command at all, only by confirming the power supply switching completion display of the substation in the next block section,
The electric car 6A can be started at any time, and the burden will be reduced accordingly.

In addition, in FIG. 3 described above, one block between the station 1 and the station m is formed in one closed section, but any number of stations may exist between the station 1 and the station m.

That is, for example, as shown in FIG. 5, this is the case where station n ... Station p is present in the information transmission line 30r between station l and station m, and information transmission lines 30q and 30s are connected to station l. That is, each station m is a station.

In FIG. 5, the electric vehicle 6A receives a substation power supply switching request command signal from the onboard controller at the substation controller in the closed section and the next closed section, when the electric vehicle 6A stops at the station l, and the ground transceiver To the controller of the substation in the next block section. In this case, it goes without saying that the condition for switching is that the electric vehicle does not exist in the information transmission paths 30r and 30s.

On the other hand, when the door switch 10 is switched from open to closed, the controller 32m of the substation in the next block section receives the signal via the on-board controller 12, and issues a power supply command to the power converter 33m to generate electricity. The car 6A receives electric power and runs. The power converter 33m stores in advance an operation pattern capable of traveling to station n, and travels to station n and stops.

After stopping at station n, the door opened and the speed signal of generator 15 was zero,
When the substation power supply switching request signal is output, the substation controller 32m in the next block section receives the signal, and the substation controller 32l in the block block section permits transmission to the ground transceiver 31q and the power converter 33l. The electric vehicle 6A is restored so that the electric power can be supplied from the electric vehicle 6A. However, since the electric vehicle 6A has already been made by the substation power supply switching request command made while the train station 1 is stopped, the electric vehicle 6A is controlled again, but there is no change. Then, when the door switch 10 is switched from open to closed, the controller 32m of the substation in the next closed section receives it via the on-board controller 12, issues a power supply command to the power converter 33m, and outputs the electric power. Take car 6A to the next station.

In this way, the electric car 6A is advanced one after another, and from station p to station m
Control is transferred to the next substation 1t in the next block section.

As described above, the electric car 6A can travel from the station 1 to the station m regardless of how many stations exist in the section between the station 1 and the station m.

Further, in the above description, the door switch is used as the condition for outputting the substation power supply switching request command signal, but the same applies when the substation switching switch 11 is used instead of the door switch.

〔The invention's effect〕

As described above, according to the present invention, when the electric vehicle travels from one specific closed section to the next closed section, power supply switching of the substation can be reliably performed without error, and the electric vehicle can travel safely and stably. It is possible to provide a possible extremely reliable traveling control method for an electric vehicle.
