Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electromagnetic induction device for a vehicle that installs an F/J 214 line in a vehicle passageway, passes an alternating current through the inductive 214 line, and guides the vehicle by the generated alternating electromagnetic field. It is.

In the electromagnetic induction system of this Yuzu vehicle, there are often several local stations along the path. Such a local station performs control such as, for example, stopping a vehicle that has arrived at the location and then starting the vehicle.

In the conventional electromagnetic induction system of this Yuzu, the power line of the local station was laid separately from the induction line, but when the total length of the passage is more than 10 km, like the ``magnetic visiting system'' of a golf cart at a golf course, etc. In some cases, the disadvantage is that the cost of installing the power line increases.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electromagnetic induction device for an axle that can reduce wiring work costs by sharing the induction 4 wire and the local station power line.

In the electromagnetic induction device for a vehicle according to the present invention, a guide wire is laid in a loop along the path of the vehicle, an AC power source is connected between both ends of the guide wire at the main station, and A capacitor is connected in series to the guide wire at one output end of the power supply, a DC power supply is connected in parallel to the capacitor, and a capacitor is connected in series to the guide wire at a local station provided in the middle of the passage. A constant voltage element having a constant voltage positive time a is connected in parallel to the capacitor, and direct current energy is supplied to the local station from both ends of the constant voltage element. It is something.

Embodiments of the present invention will be described in detail below with reference to the drawings.

As shown in the figure, in the electromagnetic induction system for a vehicle according to this embodiment, a single guide wire 2 starts from a main station 1 and extends to a vehicle 3.
The cable is laid in a loop along the path of the cable, and the end is returned to the main station 1. In the main station 1, an AC power source 4 is connected between both ends of the guide wire 20, and a capacitor 5 is connected in series to the connecting wire 2 at one output end side of the monthly AC power source 4. A power source 6 is connected in parallel via a resistor 7.

There are multiple local stations 8 along the route of the vehicle 3.
is installed. At each local station 8, a capacitor 9 is connected in series to the induction wire 2, and a constant voltage element 10 such as a Zener diode having a constant voltage characteristic is connected in parallel to each of these capacitors 9. DC energy is supplied to the load 11.

In such an electromagnetic induction device, an alternating current from an alternating current power supply 4 flows through the loop-shaped guide wire 2, so that an electromagnetic field necessary for guiding the vehicle 3 is generated around the guide wire 2. Although the guide wire 2 is cut at each local station 8, since a capacitor 9 is connected in series at each cut point, there is no problem with the flow of the current.

In each local station 8, a constant voltage element 10 having constant voltage characteristics such as a Zener diode is connected in parallel to the capacitor 9, so a DC voltage E is generated across each of the constant voltage elements 10, and each load 11 The #L voltage E can be directly supplied to the #L voltage E.

In this case, if the voltage of the DC power supply 6 is 3E, each Zener diode 1 in the three local stations 8
A voltage of 3E/3=E is supplied to both ends of 0. In general, it is difficult to maintain the voltage of the DC power supply 6 at exactly 3E, so the voltage of the voltage regulator 6 is set slightly higher than 3E, and the excess voltage is removed by a resistor 7 connected in series with the DC power supply 6.
It is best to lower it with 2. Note that if a DC power supply 6 with constant voltage characteristics or drooping characteristics is used, the output voltage will automatically change to 3.
E, the resistor 7'5r can be omitted.

In the present invention, a station where a DC power source 6 is installed is referred to as a main station, and a station where a DC power source 6 is not installed is referred to as a local station.

As explained above, along the path of the axle according to the present invention,
The guide wire is laid in a loop shape, and the main station supplies both current energy and DC energy to the guide wire.This guide wire can also be used as a power supply line to supply direct current to the local station. Energy can be supplied. In particular, in the present invention, a capacitor is connected in series to this induction wire at the local station, and a constant voltage element is connected in parallel to this capacitor to extract DC voltage. It can also be used for both purposes, significantly reducing wiring work costs.
