Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to golf score recorders, and more particularly to a golf score recorder and its method of linking up to a host computer.

[Prior art and its problems] Conventionally, at golf courses, there has been a method in which each player or his or her caddy manually records the score on the scorecard, thereby recording each player's performance on the scorecard. I've been using it. In the case of a tournament, each player returns his scorecard to the tournament after the match is over, and an operator keys each player's performance on each scorecard into a computer. Currently, grades are calculated and statistics are used to determine the final rank.

However, such a traditional method is not only statistically inefficient, but also has the risk of statistical errors such as operator miskeying. In particular, when there are a large number of players, the drawbacks of the conventional method are particularly noticeable.

The present invention was developed in view of the shortcomings of the conventional golf score entry method described above, and in addition to being able to store the player's stroke results, it also allows the stored data to be uploaded to a host computer (up-1oad), or From the host computer, various data related to the golf course stored in the computer, such as the distance of each hole, par (standard number of strokes), or various data of each player, such as the name, are downloaded to the golf score recorder. The purpose of the present invention is to provide a golf score recorder that can be used as a golf score recorder and a method for linking it to a computer.

(2) A procedure for inputting the score of each hole into the golf score recorder and storing it in memory by each player during the course of the game.

(3) Name of each player after the game is over.

A procedure for uploading various data such as scores for each hole by each player to the host computer.

In addition, instead of step (1) above, players participating in the game can directly enter various data such as the distance of each hole on the golf course, the par of each hole, and the name of each player participating in the game using input keys. You may also enter it into the score recorder.

[Function] Through the present invention, in addition to being able to memorize the player's batting results, the memorized data can be uploaded (up-loaded) to the host computer, or the data can be stored from the host computer to the computer. You can download various data related to the golf course, such as the distance of each hole, par (standard number of strokes), or various data of each player, such as name, to the golf score recorder, so you can actually While playing, the player can record the number of strokes for each hole on the golf score recorder while referring to various data regarding the golf course displayed on the golf score recorder, and store it in memory in the golf score recorder. In addition, the data stored in the golf score recorder can be transmitted to a host computer, and the data of each player can be statisticized and managed by the host computer.

Next, the functions of each key provided on the keyboard 21 located in the lower half of the front panel will be explained.

The mode selection key 15 is a selection key for switching the content displayed on the liquid crystal display 13 to either the golf course data display mode or the player data display mode.

The four display selection keys 17 (CPI to cp4) are
This is a selection key for displaying data on any of the first to fourth golf courses or the first to fourth players on the display 13.

The character input key 16 is a key for inputting the stadium name or player's name, and in conjunction with the use of the ascending order key 141 and descending order key 143, the character input key 16 is used to input English characters from A to Z or from Z to eight on the display 13. You can display them one by one in the order listed.

Then, when the desired English character is displayed, press the ENTER key 14.
By pressing 2, the English characters can be stored in memory, so the name of the golf course and the player's name can be entered in English characters.

Note that the ascending order key 141 and the descending order key 143 can also change the numbers in order.

The correction key 183 is a key used to correct data, the inspection key 182 is a key to check the accuracy of data entered by each person, and the clear key 181 is used to erase stadium data or player scores. This is the key.

In order to prevent the data stored in the memory from being accidentally erased due to an operational error, the correction key 183 is pressed only after the check key 182 is pressed and the data stored in the memory is displayed. This is the key that allows you to correct.

Further, when the correction key 181 is pressed, a ``warning message asking whether it is OK to erase the memory'' is displayed on the display 5 to alert the user.

Furthermore, by connecting online with a host computer (not shown) through an interface cable connected to the connector 11, data relating to the stadium, such as the name of the stadium, distance of each hole, par, or player's name, can be transferred from the host computer to the score recorder. can be downloaded to. That is,
Data can be entered into the score recorder from the host computer.

Also, during game play, the number of strokes can be entered simply by operating the ascending order key 143, descending order key 141, and execution key 142, and by inputting the number of strokes and bats for each player, the score recorder will display the number of strokes for all holes. It is very convenient to use because it automatically changes to the next hole until it is input. Each time the ascending order key or descending order key is pressed, the name of each player or the name of the stadium is displayed in the upper section 131 of the display 13, and the total number of at bats is also displayed on the right side of the lower section 132 of the display 13.

Next, the internal system structure of the score recorder will be explained with reference to FIG.

In FIG. 2, 2 is a central processing unit, 21 is a keyboard, 11 is a connector, 23 is an interrupt/reset control mechanism, 24 is a display control mechanism, 25 is a display area drive mechanism, and 13 is a liquid crystal display. A parallel data line and a control signal line are connected between the central processing unit 2 and a connector 11, and an external host computer can be connected online through the connector 11.

The online control method of the present invention between the score recorder and the host computer can be divided into an online main algorithm, an upload algorithm, and a self-test algorithm.

Figure 3 is a flowchart of the main algorithm when the golf score recorder and host computer are online.As shown on the right side of Figure 3, the main algorithm starts from A. First, the score recorder meets the upload or download conditions. If it is found to be correct, it stores the data shown on the display in memory and sends a signal to the host computer saying ``Ready is complete.''

Then, each individual subprogram is executed according to instructions sent from the host computer.

To be more specific, the score recorder connector 1.
After the score recorder 1 is connected to the host computer via the interface cable, first check whether the score recorder and the host computer are connected online (step 31). The central processing unit 2 of the score recorder checks the potential at the checkpoint, and if the potential at the checkpoint is low level, it means online status, and conversely, the potential at the checkpoint is high level. If there is, it indicates that you are not online.

If it is not online, the process returns to the main algorithm again (step 39). If it is online, go to step 32 and check whether the score recorder is in input mode; if it is not, go to step 39; if it is in input mode, In step 33, after cutting off the interrupt request signal from the inside, each item of data displayed on the liquid crystal display and each item of data stored in the central processing unit 2 is stored in an external memory (3 steps). 34.
35). (This allows you to
The display can return to its original state. ) Then, clear the lower area of the LCD display and the cursor, and write “LINK WITHHO8T” in the upper area of the display.
is displayed (steps 36 and 37). After standing for an additional three seconds, it sends a "ready" signal to the host computer.

Next, a description will be given with reference to the flowchart on the left side of FIG.

10 to receive the first command from the host computer.
A timer set for seconds (step 41) checks whether the host computer has sent the command by checking the pulse signal (step 43) that accompanies the command from the host computer.
If there is no pulse signal, enter the time measuring circuit and check the time (step 431). If time is 1
If it is 0 seconds, the time measurement is interrupted (step 432).
), return to step 491. If the time has not yet reached 10 seconds, return to step 42 and check again. If a pulse signal accompanying a command from the host computer is detected, time measurement is interrupted and the command is read (step 44). Step 44 and subsequent steps interpret the commands issued by the host computer. For example, if the seventh bit is 1, the host computer is ready, enters step 41, and repeats steps 41-44. If the 6th bit is 1, it indicates a download command, and step 4
Enter 61. If the fifth bit is 1, it represents an upload command, and step 471 is entered. If the fourth bit is 1, it indicates a self-test command, and step 481 is entered. If none of the above conditions apply, step 49
Return to step 1 and complete the algorithm to go online with the host computer.

The downloading algorithm will be explained with reference to FIG.

In the flowchart of FIG.
~By reading the 3 bits, the host computer gives the appropriate address to the external memory and stores the stadium name,
Download data about the stadium, player names, etc. to external memory. At the same time, characters representing the download status are displayed on the liquid crystal display 13.

Specifically, in step 462, it is determined whether the 0th to 4th bits correspond to numbers 1, 2, or 3.4 (step 463).

If any of the above numbers apply, you will enter the download algorithm. First, the 0th to 3rd bits of the read command are set as the 4th to 8th bits of the external memory in step 46.
4) In addition, the central processing unit 2 provides another 8-bit address (step 465), and the liquid crystal display 13
In the lower area of “DOWNLOAD FORM
HO8T” is displayed (step 466),
It also sends out a "ready" signal and puts the host computer into the rBUsYJ state. After receiving the "ready" signal, the host computer sequentially writes the above-mentioned data to the external memory via the interface line, releases the host computer's own rBUsYJ state, and then resets the score recorder to rBUsYJ. state. Then, the score recorder adds 1 to the external memory address, step 467.4.
68 and 469 are repeated to display the characters "COMPLETE LOADING" in the upper area of the liquid crystal display 13 and "POWEROFF &UNPLUG" in the lower area (step 460).

Complete the algorithm to download.

Next, an algorithm for uploading will be explained with reference to FIG.

In the flowchart of FIG.
~ After deciphering whether the 3-bit number is 5 or not,
A suitable address is given to the external memory, and data such as the player's name and score are uploaded to the host computer via the data line of the external memory, and the operating status is displayed on the 5 liquid crystal display 13.

Specifically, in step 472, the commands O--
Read the 3-bit number and check whether the number is 5 (step 473). If it is 5, first provide a 12-bit address from the central processing unit 2 to the external memory (step 474). ), “UPLOAD To HO” appears in the lower area of the LCD display.
Step 4: Display the text “8T CoMP”
75), and also sends a "ready" signal, causing the host computer to enter the rBUsYJ state. After receiving the "ready" signal, the host computer sequentially reads the above-mentioned data through the data line, and the host computer
Cancel the state and set the score recorder to rBUsYJ state. After the host computer clears the rBUsYJ state, the score recorder adds the external memory address plus 1. Repeat steps 477, 478, 479,
“COMPLETE” appears in the upper area of the liquid crystal display 13.
LOADING” and “POWEROFF” in the lower area.
&UNPLUG” to complete the upload algorithm.

Furthermore, referring to FIG. 6, the self-testing algorithm will be explained.

In Figure 6, in the same way as the three algorithms mentioned above, first read the numbers from the 0th to 3rd bits of the command, check whether the numbers are 1, and if they are correct, the LCD Display numbers on the display 13 and check whether the memory is normal. If the numbers in the 0th to 3rd bits of the command are not 1, code data for determination is displayed on the liquid crystal display 13.

Specifically, in the 5th step 482, the commands 0 to 482 are
The 3-bit number is read, and in step 483 it is determined whether the number of bits is 1 or not. If the number is 1, numbers and English characters are written in the upper and lower areas of the liquid crystal display 13, respectively. Display (step 48)
4) Therefore, you can visually tell whether the score recorder is normal or not. Next, in step 486, check whether the external memory is normal. If it is normal, display the result and perform a self-test. finish.

Further, if the number of the plurality of bits is not 1, an algorithm is entered to read the internal predetermined code data on the left side of FIG. 6, and predetermined characters are displayed in the upper and lower areas of the liquid crystal display, respectively. Visually identify the score recorder's specific identification number.

[Effects of the Invention] As described above, according to the golf score recorder according to the present invention, the golf score recorder of the present invention allows the player's stroke results, such as the number of strokes, bat strokes, and total strokes for each hole, to be divided into details. In addition, the memorized data can be uploaded (up-1oad) to the host computer, or various data regarding the golf course stored in the computer can be sent from the host computer, such as the distance of each hole, It is possible to download (down-1oad) per (standard n number) or various data such as names of each player to the score recorder.

Therefore, while the player is actually playing, the number of strokes for each hole, such as the number of strokes and the number of bats, are recorded in the score recorder while referring to various data regarding the golf course displayed on the score recorder. In addition to being able to store data in the score recorder, the data stored in the score recorder can be transmitted to a host computer, allowing the host computer to statistically and manage the data of each player.

In addition, the user can directly enter data for at least four players and four golf courses into the score recorder of the machine, and it can also be entered from the host computer, which is very convenient. be.
