DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time measuring system using a medium for reading and writing without contact, and using a non-contact remote reading and writing medium when a user plays a game or a game. The present invention relates to a time measurement system for measuring time.

[0002]

2. Description of the Related Art Conventionally, when a skiing competition is performed as a competition or game, for example, when measuring the time required for skiing, the starter measures the start time by pushing a start bar at a measurement start point (start point). Then, the time when the slider has passed at the measurement end point (goal point) is detected by the optical sensor, and the time when the arrival has reached is measured. The difference between the start time and the arrival time is obtained as time (or the timer is started at the start and the timer is stopped at the goal to obtain the time). At this time, the start time and the arrival time (the start signal and the arrival signal) are transferred to the counting place by wire, and the required time is calculated.

[0003]

In the above-described conventional time measurement, a wired facility is required between the measurement start point and the measurement end point, which increases the equipment cost and requires a lot of labor for installing the equipment. There was a problem that would be.

[0004] The present invention solves these problems,
Write the measurement start time at the measurement start point on the non-contact remote read / write medium carried by the user, read the measurement start time at the measurement end point, and subtract this measurement start time from the measurement end time to measure the required time The purpose of the present invention is to make it possible to measure the time required for a game or the like with a simple configuration.

[0005]

Means for solving the problem will be described with reference to FIG. In FIG. 1, medium 1
Is a medium that users carry and read / write data in a non-contact, remote read / write manner.

[0006] The medium reading / writing device 4 writes the measurement start time when the user carrying the medium 1 passes the measurement start point (or when the measurement start point is started) on the medium 1.

The clock section 6 measures the measurement start time when the user carrying the medium 1 passes the measurement start point (or when the measurement start point is started). The medium reading / writing device 14 measures the measurement start time when the user carrying the medium 1 passes the measurement end point.
Read from.

The clock section 16 measures the measurement end time when the user carrying the medium 1 has passed the measurement end point.

[0009]

According to the present invention, as shown in FIG. 1, the measurement start time measured by the clock unit 6 when the user carrying the medium 1 passes the measurement start point (or when the measurement start point is started). When the medium reading / writing device 4 writes on the medium 1 and the user who carries the medium 1 passes the measurement end point, the clock unit 16 measures the measurement end time passing the measurement end point, and the medium reading / writing device 14. Reads the measurement start time from the medium 1 and subtracts the measurement start time from the measurement end time to calculate the required time. At this time, both the time at the measurement start point and the time at the measurement end point are synchronized with the wireless standard time to synchronize the times.

Therefore, the measurement start time at the measurement start point is written in the non-contact remote read / write medium 1 carried by the user, the measurement start time is read at the measurement end point, and the measurement start time is subtracted from the measurement end time. By measuring the required time, the required time of a game or the like can be easily measured with a simple configuration.

[0011]

Next, the structure and operation of an embodiment of the present invention will be sequentially described in detail with reference to FIGS.

FIG. 1 is a block diagram showing one embodiment of the present invention.
In FIG. 1, a medium 1 is carried by a user (for example, a ski skier) and writes data (data such as a user's management number and start time (measurement start time)) in a non-contact and remote read / write manner. And a card to be read (for example, an IC card). Electromagnetic waves (radio waves), guidance, ultrasonic waves, and the like are used as means for reading and writing to the medium 1 in a non-contact, remote read / write manner. In particular, in the case of induction, a power source is generated by boosting and rectifying the power in the medium 1 from the induced voltage, so that a battery is not required.
It is convenient.

The measurement start point machine 2 is installed at a measurement start point of a competition, for example, a skiing competition, and includes a detection sensor 3, a medium read / write device 4, a start instruction input unit 5, a clock unit 6, a control device. 7, a start display 8 and the like.

The detection sensor 3 detects that the user carrying the non-contact remote read / write medium 1 has passed the measurement start point (or pressed a bar provided at the measurement start position). Instead of the detection sensor 3, the medium reading device 4 intermittently emits an electromagnetic wave (radio wave) or the like to perform polling, and any one of the mediums 1 carried by the user.
When there is a response from the user, it may be detected that the user has passed the measurement start point.

The medium read / write device 4 reads and writes data (for example, a management number, a measurement start time, etc.) on the medium 1 carried by the user in a non-contact, remote read / write manner. The start instruction input unit 5 is for inputting a start instruction to start measurement.

The clock section 6 measures the time when the vehicle has passed the measurement start point (or when the start bar has been pressed). The clock unit 6 is a clock having an accuracy corresponding to an object to be measured. In the case of a ski skiing competition, extremely high accuracy (1/100 second or less) is required. A quartz clock is used, and synchronization with the clock unit 16 of the measurement end point device 12 is performed with high accuracy. Means for performing this synchronization with high accuracy include synchronizing with the standard time of short-wave radio broadcasting, or connecting and synchronizing the clock units 6 and 16 of the two at first, and then starting the measurement start point machine 2 and After connecting to the measurement end point device 12 or the measurement start point device 2 in which the clock section 6 is integrated and the measurement end point apparatus 12 in which the clock section 16 is integrated, the measurement start point and measurement are performed. Carry to the end point.

The control device 7 performs various controls, and instructs the medium read / write device 4 to write data (management number, measurement start time, etc.) on the medium 1 carried by the user. It is.

The start display 8 displays a start instruction and the like for a user (for example, a ski skier) who carries the medium 1. The measurement end point machine 12 is installed at a measurement end point of a competition, for example, a skiing competition, and includes a detection sensor 13 and a medium reading / writing device 1.
4, a clock unit 16, a control device 17, a result display 18, and the like.

The detection sensor 13 detects that the user carrying the non-contact remote read / write medium 1 has passed the measurement opening end point, and is an optical sensor or the like. The medium reading device 14 reads and writes data (eg, management number, measurement start time, etc.) of the medium 1 carried by the user in a non-contact, remote reading and writing manner.

The clock section 16 measures the time when the vehicle has passed the measurement end point, and the detection sensor 13 detects that the user (eg, ski skier) who has carried the medium 1 has passed the measurement end point. This is to measure the time when it is done. The clock unit 16 is a clock having an accuracy corresponding to an object to be measured.
Since very high precision (less than 1/100 second) is required, a high-precision quartz clock is used, and synchronization with the clock unit 6 of the measurement start point machine 2 is performed with high precision. Things.

The control device 17 performs various controls, and instructs the medium reading / writing device 14 to read data (management number, measurement start time, etc.) from the medium 1 carried by the user. It is.

The result display 18 displays the time required for the user (for example, ski skier) carrying the medium 1 to pass from the measurement start point to the measurement end point.

Next, the operation of the configuration shown in FIG. 1 will be described in detail. (1) In response to the input of a start instruction from the start instruction input unit 5, a start display is performed on the soot display 8. When the user who sees this passes the measurement start point (for example, the measurement start point of ski skiing competition) by carrying the medium 1 (or purchased) passed in advance (or presses the start bar), the detection sensor 3 is activated. The passage of the measurement start point is detected, and the clock unit 6 measures the measurement start time in response to the detection.

(2) The medium reading device 4 writes the management number and the measurement start time on the medium 1 carried by the user in a non-contact and remote reading manner. Then, the user carries the medium 1 on which the measurement start time is written and proceeds toward the measurement end point (when skiing, the user skis).

(3) In response to the detection sensor 13 detecting that the user carrying the medium 1 has passed the measurement end point, the clock unit 16 measures the time when the user passed the medium 1 and reads and writes the medium. The device 14 reads the management number and the measurement start time from the medium 1 carried by the user. Then, the control unit 17 calculates the required time by subtracting the measurement start time from the measurement end time. The user corresponding to the management number on the result display 18 (for example, the name of a skier)
The required time is displayed in association with.

As described above, the user uses the measurement start time of the measurement start point only by passing the measurement start point and passing the measurement end point by carrying the medium 1 passed (or purchased) in advance. Then, the required time is calculated by subtracting the measurement start time read from the medium 1 from the measurement end time at the measurement end point. This makes it possible to easily measure the required time from a certain point to another point only by the user carrying the non-contact remote read / write medium 1 (for example, an IC card).

FIG. 2 shows an example of the internal data format of the IC card of the present invention. This is an example of an internal data format in which an IC card is used as a medium 1 in FIG. 1 and is written in a non-contact manner in a remote read / write manner. The start time when passing a measurement start point is associated with a management number. Here, (measurement start time) is written in units of ms (milliseconds).

Next, the operation when the configuration shown in FIG. 1 is used for ski skiing will be described in detail according to the sequence shown in the flowchart of FIG. In FIG. 3, S1 gives a start instruction. This means that a start instruction to start skiing is input to the skiing skier as a user from the start instruction input unit 5 in FIG.

At step S2, a start display "GO" is displayed. In response to the input of the start instruction from the start instruction input unit 5 in S1, the start display "GO" is displayed on the start display 8.

At S3, the clock measures the start time. This corresponds to the start display “GO” in S2, and the clock unit 6 measures the start time (measurement start time) at which the skier started pressing the start bar to start.

In step S4, the start time is transmitted to the IC card 11 carried by the skier. S5 is S4
Is transmitted to the IC card 11. As shown in FIG. 2, the medium read / write device 4 of FIG. 1 writes a management number and a start time in a remote read / write manner in an IC card 11, which is a medium 1 carried by a skier, in a non-contact manner. The skier carries the IC card 11 on which the management number and the start time are written,
Glide to the goal.

In step S6, the ski skier carrying the IC card 11 arrives near the goal. In step S7, the start time is received from the IC card 11. This means that the medium read / write device 14 of FIG. 1 reads the management number and the start time in a non-contact, remote read / write manner from the IC card 11 carried by the skier who has arrived near the goal.

In step S8, the goal time is measured. this is,
The detection sensor 13 of FIG. 1 detects that the ski skier has reached the goal, and the clock unit 16 measures the goal time (measurement end time) at this time.

In step S9, the goal time-start time → the required time is calculated. This is because the detection sensor 13 of FIG.
The start time read from the IC card 11 in S7 is subtracted from the goal time measured by the clock unit 16 when it is detected that the ski skier has reached the goal, thereby obtaining the required time.

In step S10, the result "required time" calculated in step S9 is displayed on the result display 18 together with the number and name of ski skiers corresponding to the management number. S1
1 prints the "required time" calculated as a result of S9 together with the ski slider number and name corresponding to the management number.

As described above, the time when the ski skier starts the measurement start point is written in the IC card 11, and the goal time when the ski skier carrying the IC card 11 reaches the goal is detected. And the start time is read from the IC card 11 and the required time is calculated by subtracting the start time from the goal time.
The required time is displayed and printed together with the ski run number and name corresponding to the management number. As a result, it is possible to measure the time required from the start point to the goal point with a simple configuration by simply carrying the remote read / write type IC card 11 in a non-contact manner.

[0037]

As described above, according to the present invention,
The measurement start time at the measurement start point is written on the non-contact remote read / write medium 1 carried by the user, the measurement start time is read at the measurement end point, and the required time is obtained by subtracting this measurement start time from the measurement end time. Since the configuration for measuring is adopted, the required time for a game or the like can be easily measured with a simple configuration. This eliminates the need for a wired connection between the conventional measurement start point and the measurement end point, and the user simply carries the non-contact remote read / write medium 1 with a simple configuration and easily at both points. The required time between them can be measured.
