Description

Description: TECHNICAL FIELD The present invention relates to a remote control type play device, and more particularly to a remote control type play device for remotely controlling a moving body using a digital propo signal.

[Prior Art] Today, remote control devices are widely used in various fields. For example, in the field of toys, remote control devices are used for remote control of mobile objects such as car toys, and game machines. In the field, it is used for remote control of a moving body that moves within a predetermined play field.

By the way, various control amounts of such a moving body are often analog amounts such as speed and direction. Therefore, a digital signal obtained by combining such remote control control with “0” and “1” pulses. However, there is a problem in that the combination of signals becomes complicated, resulting in an increase in the number of parts in the circuit and a decrease in the signal transmission speed.

For this reason, a remote control device using a digital propo signal that represents the analog control amount of a moving body with a pulse output time interval has been conventionally known. According to this device, one analog control amount is simply output as a pulse. Since it only needs to be expressed by time intervals, it has an advantage that the circuit configuration required for signal transmission and reception becomes extremely simple and the signal transmission speed is also extremely high.

In particular, when such a digital propo signal is used, since the control of the moving body can be accurately performed in an analog manner, for example, the control amount such as the speed and the position of the moving body can be continuously controlled in a wide range. It becomes possible.

[Problems to be Solved by the Invention] However, in the conventional remote control device, radio waves were used for transmitting such a digital propo signal.

For this reason, noise may be mixed in the transmission signal, or radio waves of other types are likely to be mixed, and the situation in which the control of the moving body is temporarily disabled occurs. There was a problem of being unsuitable.

In order to prevent such a situation, it is necessary to increase the transmission output from the transmitter and to install a large antenna on the moving body that matches the transmission frequency. However, the increase in the transmission output is related to the Radio Law. However, there is a problem in that a large antenna is provided on the moving body, which hinders the good operation of the moving body itself, and neither of them is an effective decisive factor.

In particular, when the moving speed of a remotely controlled moving body is extremely high, if the inoperable state occurs temporarily, the moving body collides with another object and the moving body itself is damaged, Further, since it damages other objects, effective measures against it have been desired.

Further, there is no conventional remote control device capable of satisfactorily controlling a plurality of moving bodies.

[Object of the Invention] The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a remote control type play device capable of satisfactorily remote controlling a plurality of moving bodies by using a digital propo signal. To provide.

[Means and Actions for Solving Problems] In order to achieve the above-mentioned object, a remote control type playing device of the present invention has a plurality of moving bodies that move within a predetermined play field, and each of the above-mentioned moving objects toward the play field. A remote control device for transmitting a remote control signal of a mobile body, wherein the remote control device outputs a control signal of each mobile body according to an operation of a player, and a predetermined channel for each mobile body. A plurality of assigned control signals of the respective mobiles are converted into digital propo signals, and the digital propo signals are modulated and transmitted as remote control signals to the play field from different directions optically through the assigned channels. Each of the mobile units optically receives a common transmission signal transmitted from the plurality of transmitters, and From the received signal, it includes a receiver for outputting a remote control signal assignment channel of its own separately from the remote control signal assignment channel other machine, characterized in that it is remotely controlled by the remote control device.

[Embodiment] Next, a preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a preferred embodiment of the remote control device of the present invention used in the game device,
The device of the embodiment is a game machine main body 18 as a remote control device.
It includes a transmitter 20 provided on the side and receivers 22A and 22B provided on the sides of the moving bodies 10A and 10B, respectively.

Various control signals of the moving bodies 10A, 10B output by operating the operation levers 16A, 16B are input to the transmitter 20.

The characteristic feature of the present invention is to convert the control signals of the mobile units 10A and 10B into digital propo signals and optically transmit the digital propo signals from the transmitter 20 to the receiver 22 as optical signals.

Therefore, in the transmitter 20 of the present invention, the control signals of the mobile units 10A and 10B are converted into digital propo signals corresponding to the control amounts, and the digital propo signals thus converted are modulated for remote control.

Then, each of the receivers 22A and 22B optically receives the optical signal thus transmitted, demodulates and detects a digital propo signal from the received signal, and based on the digital propo signal thus obtained, It controls the moving bodies 10A and 10B.

FIG. 4 shows a specific circuit configuration of the transmitter 20. The transmitter 20 of the embodiment has assigned channels CH1 to CH3.
A control signal of the moving body 10A output by one player operating the operation lever 16A is input via, and the other player operates the operation lever 16B via the assigned channels CH4 to CH6. The output control signal of the moving body 10B is input.

The control signals thus input via the channels CH1 to CH6 are input to the corresponding voltage signal converters 30-1, 30-2, ... 30-6, respectively, as shown in FIG. As shown in FIG. 3, these control signals are converted into voltage signals having a voltage value corresponding to the control amount and input to the digital radio transmitter 32.

As shown in FIG. 5, the digital radio generator 32 outputs the voltage signal thus input to the channels CH1 to CH6.
In this order, the pulse trains are converted and output at time intervals corresponding to the voltage values.

That is, the digital radio transmitter 32 of the embodiment converts the input voltage signal of each channel into a pulse train (digital radio signal) output at time intervals corresponding to the voltage value. Then, the parallel signals of the respective channels CH1 to CH6 output from the respective voltage generators 30 are converted into serial signals of the channels CH1 to CH6 as shown in FIG. 5, and these series of serial signals are converted into one frame 20.
Output to the modulator 34 at a cycle of ms.

Further, a carrier of 40 KHz as shown in FIG. 5 is inputted from the oscillator 36 to the modulator 34, and the modulator 34 modulates the digital propo signal using this carrier and is shown in FIG. LED driver 38
To enter.

The LED driver 38 drives the LED 40 based on the modulated wave input in this way, converts the digital propo signal modulated from the LED 40 into an optical signal for remote control, and receives the signal from the receiver 22A.
And send it to 22B.

FIG. 6 shows a specific configuration of the receiver 22. In the figure, (A) shows the receiver 22A provided in the moving body 10A, and (B) in the figure shows the movement of the other. Each represents a receiver 22B provided within the body 10B.

The receiver 22 of the embodiment optically receives the optical signal transmitted from the transmitter 20 by the photodiode 42, and outputs the received signal to the demodulation unit 44 as shown in FIG. The demodulation unit 44 detects and demodulates the digital propo signal from the received signal thus input, as shown in FIG.
The digital propo signal thus obtained is output to the decoder 46.

As shown in FIG. 7, the decoder 46 converts the digital propo signal thus input into a pulse having a pulse width corresponding to the output time interval of each pulse, and the thus converted pulse is converted into each channel. The output is distributed to the drive circuits 48-1, 48-2 ... 48-6 provided for each.

In the embodiment, channels CH1 to CH3 represent control signals for the mobile unit 10A, and channels CH4 to CH6 represent control signals for the mobile unit 10B.

Therefore, the decoder 46 of one of the receivers 22A has driving circuits 48-1 to 48-only corresponding to the output channels CH1 to CH3.
3 is connected and the decoder 4 of the other receiver 22B
6 has a drive circuit 48-4 corresponding to channels CH4 to CH6.
~ 48-6 are connected.

The drive circuits 48-1 to 48-6 drive the actuators 50-1 to 50-6 provided correspondingly.

In this way, the remote control device of the embodiment transmits the analog control signals of the moving bodies 10A and 10B as digital transmitter signals corresponding to the analog control amount to the transmitter 20.
Since the optical signal is transmitted from the receiver to the receiver 22, even if there are radio waves and other noise in the surroundings, the mobile unit can be controlled well by the digital propo signal without being affected by such noise. It becomes possible.

In particular, according to the device of the present invention, when remote control of a moving body is performed within a short range, signals can be transmitted and received by an optical signal of low output without being affected by noise. In some cases, because the optical signal does not spread over a wide area,
Even when similar optical remote control devices are present in the surroundings, it is possible to perform excellent remote control between these devices without mutual interference of optical signals.

When transmitting and receiving the control signal by using a high-power optical signal, as shown in FIG.
It is preferable to provide a light shielding wall 60 around 0 to prevent the optical signal from leaking to the outside of the play field. By doing so, even when a plurality of optical remote control devices are used in close proximity to each other. It is possible to perform good remote control without causing mutual interference with the optical signal of the other party.

When the optical remote control device is used in a game machine as in this embodiment, a plurality of LEDs 40 are provided around the play field 100 at predetermined intervals as shown in FIG.
Is installed, and optical signals can be simultaneously transmitted from at least two locations toward any position in the play field 100.

By doing so, for example, the play field 10
Even if two moving bodies 10A and 10B travel within 0 and the optical signal directed to one moving body is blocked by the other moving body, one traveling body is transmitted from different directions. It will receive the optical signal and be well controlled.

In particular, when using an optical signal as in the present embodiment, in the game contents in which the moving bodies 10A and 10B move freely,
It is conceivable that an optical signal directed to one moving body is often temporarily blocked by the other moving body.

Further, in the present invention, since the moving body is controlled at the pulse output time interval, if the optical signal is temporarily blocked, the moving body 10A and the like cannot be controlled by the digital propo signal. Therefore, when the moving body 10A or the like is extremely fast, it is necessary to install a plurality of LEDs 40 so that the white light signal is not temporarily blocked.

Further, in the above embodiments, the case where the control device of the present invention is used in a game machine has been described as an example, but the present invention is not limited to this, and is applicable to remote control of various toys such as automobile toys and other applications. Can be similarly used.

[Effects of the Invention] As described above, according to the present invention, transmission and reception of a plurality of digital propo signals for controlling a moving body can be performed between a plurality of transmitters and respective receivers without being affected by noise or the like. It is possible to provide a remote control type amusement device which is capable of optically performing a remote control of a plurality of moving bodies moving in a predetermined play field.

Further, according to the present invention, the remote control device transmits the remote control signal from the plurality of transmitters to each of the plurality of mobile bodies in substantially real time without interruption and without causing interference. Moreover, since the receiver of each mobile unit that receives this transmission signal may be configured to selectively output the signal of its own assigned channel from the received signal, the configuration is extremely simple and inexpensive. Becomes

In particular, according to the present invention, the control signal of each mobile unit is allocated wirelessly to each mobile unit as compared with the case of wireless transmission together with an ID code, etc. Is simplified, which allows the structure of the receiver provided in each moving body to be simple and inexpensive.
