BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FM-modulated digital data wireless communication method, and more particularly to a digital data wireless communication method when data that has been damaged by some cause is received.

[0002]

2. Description of the Related Art As a conventional wireless communication method for digital data, there is known a wireless communication method for a video game by AM modulation as shown in FIG. Thus, this figure is a block diagram showing a wireless communication method of a video game by AM modulation. It consists of a video game machine 3. The transmitter 1 comprises a key switch 5 coupled to the CPU 4 and a transmitter circuit 6 coupled to the CPU 4, and the receiver 2 comprises a receiver circuit 8 coupled to the CPU 7 and the CPU 7. The section 2 is connected to the video game machine 3. Thus, in the transmission of the wireless communication method of the video game by the AM modulation, the digital data is created based on the switching operation by the key switch 5, and the digital data is transmitted by the transmission circuit 6. The data transmitted by the AM modulation is received by the receiving circuit 8
Is received by the CPU 7, data is created by the CPU 7, and the data is sent to the video game machine 3.

[0003]

In the conventional digital data wireless communication by the AM modulation, when a trouble such as noise occurs, the video game is executed despite the switching operation of the key switch 5. The character of the machine 3 stops, and the character does not move until the obstacle such as the noise disappears, halving the interest of the operator of the video game machine 3.

Therefore, even if an obstacle such as a noise occurs during the digital data wireless communication and the digital data corresponding to the switching operation is erased or transformed, for example,
There is a technical problem to be solved in order to prevent the motion of the character of the video game machine 3 from stopping, and the present invention aims to solve the problem.

[0005]

The present invention has been proposed in order to achieve the above object, and in digital data wireless communication, the modulation method is FM modulation, and the transmitted data is received. A receiving circuit is provided, and the receiving circuit is a CP
If the data received by coupling the U and the signal meter is further coupled with the CPU, and the CPU is coupled with the electronic device,
It is intended to provide an FM-modulated digital data wireless communication method characterized in that data immediately before being damaged by a CPU is extracted.

[0006]

The present invention is a digital data wireless communication method by FM modulation using a signal meter. When the signal meter is on, key data (digital data based on a switching operation) is sent to an electronic device and at the same time a CPU is sent.
The digital data is retained within. When the signal meter is off, the CPU creates off data. Next, even when the signal meter is on and the data is deformed due to a noise or the like, the key data immediately before the deformation held in the CPU continues the switching operation. As long as it is being sent, the electronic device will continue to operate based on the immediately preceding key data.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS. FIG. 1 shows a block diagram of wireless communication of a video game machine using a signal meter. The figure comprises a transmitter 9, a receiver 10 and a video game machine 11 connected to the receiver 10. Also, the transmitter 9 is a CP
The key switch 13 connected to the U12 and the transmitting circuit 14 connected to the CPU 12 are provided, and the receiving unit 10 is a CP.
U17, a receiving circuit 15 connected to the CPU 17, and a signal meter 16 connected to the receiving circuit 15 and the CPU 17, and the CPU 17 is connected to the video game machine 11.

Thus, in transmitting the wireless communication of the video game machine 11 by FM modulation, the CPU 12 creates digital data by operating the key switch 13, and the digital data is transmitted from the transmitting circuit 14. The transmitted digital data is received by the receiving circuit 15, the signal meter 16 holds the digital data in the CPU 17, and the receiving circuit 15 sends the digital data directly to the CPU 17, and the television It is transmitted to the game machine 11. At this time, for example, when the received digital data is deformed for some reason, the digital data immediately before the deformation held in the CPU 17 is sent to the video game machine 11.

The operation sequence of the above embodiment will be described below with reference to the flow chart of FIG. The figure shows a flowchart on the receiving side of digital data wireless communication using a signal meter. First, turn on the power (step 18),
Then, reception of digital data wireless communication is started (step 19). Next, it is determined whether the signal meter is on or off (step 20). In step 20, if the signal meter is off, off data is created (step 21), and the process returns to step 19. If the signal meter is turned on in step 20,
It is determined whether the digital data is ON / OFF data or other than ON / OFF data due to a noise or the like (step 22). Then, if it is the on / off data in the step 22, it is judged whether it is the off data or other than the off data (step 24). Then, if it is other than OFF data in the step 24, key data processing is performed (step 25). If the data is other than the on / off data in step 22, the CPU outputs the data just before the digital data is deformed by the noise to the video game machine 11 (step 23). Further, if it is off data in step 24, off data is created (step 2
1) Return to step 19.

Thus, in the digital data wireless communication method using the signal meter, even if the data is deformed for some reason, the CPU sends the data immediately before the deformation to the electronic device, and the data immediately before the deformation causes the electronic device to be changed. Will work. Thus, when the present invention is applied to the video game machine, the data received while the operator is performing the switch operation of the controller is deformed due to noise or the like, and the switch operation is performed on the video game machine side. Even if the corresponding signal cannot be transmitted, the digital data stored in the CPU 17 by the signal meter 16, that is, the digital data corresponding to the switching operation immediately before the transformation is transmitted from the CPU 17 to the video game machine 11
Therefore, the character of the video game machine 11 will continue the predetermined operation by the signal immediately before the deformation, so that the video game can be enjoyed without halving the interest of the operator.

The present invention can be modified in various ways without departing from the spirit of the present invention, and it goes without saying that the present invention extends to such modifications.

[0012]

According to the present invention, by utilizing the signal meter for digital data wireless communication, when the transformed data is received, the immediately preceding data output from the CPU is sent to the electronic device. Further, since the modulation method is FM modulation, there is little influence of noise or the like, and the invention exhibits exactly various functions such as highly reliable communication.
