[0003]

[Problems to be Solved by the Invention] In the conventional automatic operation circuit of the railway model, the rail is cut and insulated at the stop position of the vehicle, as in the electronic work of the railway model described above, and the vehicle is mounted on the insulated rail. When entering the car, it automatically stops, and when starting, the insulated rail is powered to start the car. In such a circuit, very complicated wiring is required, such as cutting and insulating the rail at several places and connecting a power supply line to the insulated rail. For this reason, such an automatic driving circuit is not completed as a product because it cannot be out of the hobby.

This invention has no inconvenience such as providing a large number of insulating parts on the rail and connecting a power supply line to the insulating rail, and distributes the vehicle to a simple and unprecedented branch rail. It is intended to provide an automatic driving circuit having a wide range of applications in which the driving mode can be easily changed.

[0005]

According to the first aspect of the present invention (see FIG. 1), detection units A and B which emit a signal when a vehicle enters a predetermined position and signals from the detection units A and B are used. A circuit 1 which outputs signals of two systems a and b which are opposite to each other such as ON and OFF, delay circuits 2 and 3 which are connected to the two systems a and b, and a power supply circuit c to a vehicle which is connected to the delay circuits 2 and 3. , D for a predetermined time, a reverser 4 for inverting the power supply circuits c, d, and circuits 8, 9 connected to the two systems a, b and connected to the rail point drivers PA, PB. , A circuit 6 which alternately drives the rail point drivers PA and PB that branch by connecting to one of the two systems a and b to distribute the vehicle to the respective branch rails.
It is an automatic driving circuit of a model railway for direct current having.

The invention of claim 2 is as follows (see FIG. 2):
In the invention of claim 1 described above, the automatic driving circuit of the alternating current model railway has a voltage conversion circuit 10 for switching the vehicle operating voltage to the one-shot time vehicle-mounted on-vehicle reversing relay driving voltage instead of the reversing device 4.

[0007]

First, the invention of claim 1 will be described.

When there are detection units A and B on the left and right sides of a straight rail (see FIG. 3), when the vehicle enters a detection unit at a predetermined rail position, for example, A, one of two systems a and b is ON and the other is OF.
It emits F or digital signals 1 and 0. When the system a becomes an ON signal, the signal operates the reverser 4 and the breaker 5 via the delay circuit 2. The vehicle D passes through the time detection unit A in the delay circuit 2 and stops. The x part is the stop position. Since the circuit breaker 5 has been operating for a predetermined time, the vehicle stops and rests for that time. After the quiescent time has passed, the power supply circuits c and d have already been converted to +-by the reversing device 4, so that they start running in the opposite direction. Then, when the vehicle enters the detecting section B, it runs in the opposite direction again like the previous time. Vehicle D automatically reciprocates on the rail as many times as necessary.

When the straight rail is bifurcated midway (see FIG. 4), two vehicles are driven. Points will be provided at the rail branches. Circuits 8 and 9 are connected to the drivers PA and PB at this point, respectively, and a switch 7 transmits a signal of one system to the circuit 6 that distributes the signals to the branch rails R and S. The detection unit A is provided on both rails R and S. Therefore, the system a becomes an ON signal regardless of which detection unit A detects. (In the above description, the circuit 6 is connected to the a system for convenience).

Vehicle E is now waiting on rail R. One of the points on the rail R side (driver PA) is closed. In a commonly used selectable rail point, power is not supplied to the rail on the side where the point is closed. On the other hand, the vehicle D passes through the point, enters the rail S, and enters the detection unit A. As a result, the circuit breaker 5 and the reversing device 4 work to stop the vehicle D at the x position, the rail point PB side is closed and the rail is not supplied with power, and the vehicle continues to stop. Rail point driver P by circuit 9
When the side A opens, power is automatically supplied to the rail R and the vehicle E starts running. The vehicle E enters the detection unit B, stops at the X position, starts running in the opposite direction again after a predetermined time, enters the original rail R, stops at the X unit by the detection unit A, and the rail point driver PA side closes conversely this time. Then, the vehicle E stops, the point PB opens, and the vehicle D starts running.

As described above, the point drivers PA and PB alternately operate by the action of the circuit 6 by the detecting section A connected to the same circuit. Further, if the detection unit A is provided in front of the rail branching unit, only one detection unit A is required, and the time until the delay circuits 2 and 3 are adjusted and stopped may be extended.

When the rails are endless rails as shown in FIG. 5 and vehicles F and G are on branch rails T and U, respectively,
Detection units A and B are provided on both rails T and U, respectively. Then, the two systems a and b related thereto are switched by the switch 7 through the circuits 8 and 9, respectively, and the rail point drivers PA and PB are provided.
Connect to. If the power supply circuits c and d are directly connected to the rail without being connected to the reversing device, the vehicles F and G both run in the same direction as shown in FIG.

Next, the invention of claim 2 will be described. This invention is of the type that supplies alternating current to the rails and is made of, for example, Merclin (trademark). In the case of reverse rotation, this railway model has a mechanism in which a vehicle-mounted relay operates and the motor reverses by switching to a voltage (24 V) higher than the running voltage (0 to 12 V). The voltage conversion circuit 10 is used in place of the reversing device 4 of the circuit of the above-mentioned device. Therefore, a one shot high voltage is applied to the vehicle by the signal of the detection unit. In this case, it is necessary to turn on the circuit breaker 5 for one shot time. The circuit h shows the circuit. Circuits e and f are running voltage circuits, circuits e and g are high voltage circuits,
The voltage conversion circuit 10 switches the circuits e and f.
In the case of driving two vehicles as shown in FIGS. 4 and 5 in this AC type, it is necessary to insulate the rail at the stop position and supply power to this insulated rail when the circuit breaker supplies power again.
In addition, the insulation of the rail is extremely easy in the AC type model.

[0014]

[Embodiment] The detection unit AB, which emits a signal when a vehicle enters a predetermined position, is provided with a switch that energizes when a wheel of the vehicle touches a rail, and a light switch works when the vehicle crosses the position. A photodetector that emits a signal or a detector that operates a reed switch provided on a rail by a magnet provided on the vehicle is used. C is one pole that makes a pair with the detection unit AB.

As the circuit 1 which outputs signals of two systems a and b which are opposite to each other, such as ON and OFF, by a signal of this detection section, a circuit of a latching relay and a flip-flop is used.

As the delay circuits 2 and 3, a circuit composed of C and R, or an IC 555 is used.

A relay provided with a timer circuit is used as the circuit 5 which shuts off the power supply circuit for a predetermined time. For the reversing device 4, two circuits of latching relays are used in the DC-driven model railway circuit. In AC drive, a relay provided with a one-shot power supply circuit is used. The circuit 6 which alternately drives the branching rail points to distribute the vehicle to each branching rail is a stepping relay or IC 401 of JK or FF.
Use 3B to drive the relay.

The switching device 7 uses a two-circuit snap switch. As a circuit for driving the rail point, a circuit for supplying one-shot power is provided to drive the relay.

[0019]

According to the present invention, the rail at the stop position of the vehicle is cut, the portion is made into an insulating rail, and further, automatic operation is easy without a troublesome circuit such as connecting a power supply line to this insulating rail. it can. Since a delay circuit until the stop is provided after the detection unit, when driving two vehicles, one can be operated without stopping at the detection unit (when one vehicle is stopped at the detection unit, the other vehicle is stopped). Cannot move).

It is a product with a wide market and a wide range of applications by simply changing the connection between the rail and the circuit.
