FIG. 2 is an explanatory diagram showing an outline of the arrangement of each of the above-mentioned devices f2a to f5.

For example, the inside of the stadium 9 is divided into six blocks (for example, tennis courts), and one input device 2a to 2f is installed in each block 9a to 9f.

Specifically, when the game is tennis, the input devices 23 to 2f are mainly operated by the referee, so they are installed at the position where the referee sits. Further, the relay device 3 is
The data receiving device 4 is installed in a place where each of the blocks 9a to 9f in the stadium 9 can be viewed in its entirety, and the data receiving device 4 is installed near the result display device 5, which is installed in an appropriate place in the stadium 9.

Next, the operation of the wireless competition score display system configured as described above will be explained with reference to the flowcharts shown in FIGS. 3 to 6. However, in FIG. 3, the input devices 2a, 2b,
Flowchart showing the operation of..., Figure 4 is the relay device 3
5 is a flowchart showing the operation of the data receiving device 4, and FIG. 6 is a flowchart showing the operation of the score display device 5.

The wireless devices 212a and 32.42 in each of the devices 2a to 4 are configured to transmit and receive radio waves of the same frequency such as the 450 MHz band, and the modulation method for the radio waves is an FM modulation method. It has been adopted. Also, FM
The data signal serving as the source signal for modulation is an MSK modulation signal in which two frequencies within the audio band are switched according to the rHJ level and the "L" level of the data.

In addition, since each device 2a to 4 handles radio waves of the same frequency, each device 2a to 4 handles radio waves of the same frequency.
A station address, which is a two-digit number different from each other, is set in each of the stations 4 as identification means. In the following,
As the station address, 0 is input to each of the input devices 2a to 2f.
1,02.05°06.07.0B, 0 for relay device 3
3. It is assumed that 04 is set in the data receiving device 4.

The operation of this system begins, for example, with the transmission of radio waves from the input device 2a installed in the block 9a.
The operation is started by data input from the key human power unit 221a operated by the referee when any player raises points (step 521). At this time,
The data transmitter 214a checks whether there is data from another station on the wireless line based on the presence or absence of a signal input from the carrier detector 213a (step 522). Then, when it is confirmed that there is no data from other stations on the wireless line, the data transmitting section 214a transmits the data to the key human power section 221a.
In order to inform that the radio wave to be transmitted is a radio wave to the relay device 3, the score data from the key human power section 221a is sent to the data receiving device 4. In order to indicate that the data is to be sent to the wireless device 212a, a header including the number 04, which is the station address of the data receiving device 4, is generated, and an MSK signal modulated by this data is generated. Send to. The radio device 212a transmits radio waves FM modulated by this MSK signal from the antenna 211a (step 523).

Thereafter, an MSK signal modulated by the score data is generated and sent to the wireless device 212a. Wireless device 212a
Then, radio waves FM modulated by this MSK signal are transmitted from the antenna 211a (step 524). However, the above-mentioned score data has a station address 01 indicating that it is data from the input device 2a, and an identification signal for identifying which player's score belongs to the beginning part.

The radio waves transmitted from the antenna 211a in step S24 are received by the relay device 3.

In the relay device 3 that has received the radio wave, the operation proceeds to steps S31 and S32 through a series of operations of the antenna 31, the wireless device 32, and the carrier detection section 33, and the station address 03 extracted by the data reception section 35 is Since the value matches the value set for itself, the operation proceeds from step S33 to step S34, receives the next data, and stores the received data internally. The data at this time is
Since the station address is 04 and the score data,
The data transmitting unit 34, which has received and received the data stored in the data receiving unit 35, sends a header containing the station address 04 to indicate that the radio waves transmitted from this are radio waves to the data processing device 4. (Step 5)
35), the MSK signal indicating score data including the station address 01 and the identification signal is sent to the wireless device 32', and radio waves are transmitted by the wireless device 32 and the antenna 31 (step 35).
knob 836).

The radio waves transmitted from the relay device 3 are transmitted to the input devices 2a to 2f.
and is received by the data receiving device 4.

In the input devices 2a to 2f, antennas 211a to 211
f, wireless device 212a (212b to 212f: not shown), carrier detection unit 213a (213b to 213
f: (not shown) confirms that there is data on the wireless line, but at this time, since the data transmitting devices 2a to 2f have no data to transmit, they remain inactive (step 511). Furthermore, if there is data to be transmitted, data transmission is temporarily put on hold until there is no more data on the wireless line (step 51).
2).

On the other hand, when the data receiving device 4 that has received the radio wave is notified by the antenna 41, wireless device 42, and carrier detection unit 43 that the radio wave has been received (step 541).
, the header is received in the data receiving section 44 (step 542), and the station address contained therein is extracted. At this time, after confirming that the station address is 04, step S43 to step S44
Then, the next score data is received by the data receiving section 44 and transferred to the control section 51 of the score display device 5 (step 545), and the operation ends.

The control unit 5I extracts the station address 01 added to the beginning of the transferred score data, recognizes that the following score data is data from the block 9a, and retrieves the station address 01 added to the beginning of the transferred score data. The player extracts the identification signal and recognizes which player the score belongs to.

The control unit 51 stores tennis scoring rules in advance, such as how to add points when the score data is derived, so the control unit 51 determines how to respond based on the derived score data. The score of the player corresponding to block 9a is calculated (step 581), and the calculation result T0 is stored (step 582). Here, if it is the first time for the player in flock 9a to score, the calculation result (score at that point) To
At the same time, the score data indicating the score 15 is sent to the display unit 52, and the score of the player who scored in block 9a is displayed (step 583).

After this, when the score data of the corresponding player in block 9a is derived again, the previously stored score 15 is read out,
This score 15 plus 15, 30, is stored as a new score T0, and score data indicating the score 30 is sent to the display unit 52 to display the score (step 583
).

In the above embodiment, the operation was explained only for the score of one player in the block 9a, but the operation for the other blocks 9b to 9f was explained.
It goes without saying that the operation of this embodiment is exactly the same as that of the above embodiment, except that the station address is different. In this case, even if score data is arbitrarily transmitted from each input device 23 to 2f of each block 98 to 9f as the competition progresses, it is not possible to identify which player in which block the score data belongs to. Therefore, the score of the player is immediately displayed at the display location of the display unit 52 corresponding to the player.

Furthermore, in the above embodiment, as for the method of transmitting and receiving radio waves between the human-powered devices 2a to 2f, the relay device 3, and the data receiving device 4, continuous transmission is performed from one side, and data is not accurately received. Although this is explained as an operation that omits the error handling step that confirms that the A procedure for transmitting data is added to the data, and a configuration is adopted to prevent transmission errors caused by disturbances or the like.

Furthermore, in the above embodiment, the wireless device 212a.

Although the case where the 450 MHz band is used as the frequency transmitted and received by ~212f, 32.42 is explained, it is not limited to this (other frequencies include, for example, the frequency of an empty channel in the TV broadcast band). etc. can be used.

Furthermore, in the above embodiment, the case where the competition result display system of the present invention is applied to a tennis competition is explained, but as other application examples, it can be applied to various competitions such as a golf competition and an indoor table tennis competition. It is possible.

(Effects of the Invention) The wireless competition results display system of the present invention has a configuration in which the input device, the relay device, and the data receiving device are each connected wirelessly, so there is no need for wiring, etc. is extremely easy to perform. Therefore, it is extremely easy to add new equipment as the stadium expands, or change the arrangement of equipment by changing blocks within the stadium.
