DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timekeeping system, and more particularly to a portable terminal which receives a weak radio wave from a fixedly installed transmitter and outputs or displays the time at which the radio wave was received.

[0002]

2. Description of the Related Art In long-distance running in athletics, a runner in a race carries a clock to judge his / her own pace, and reads a lap time by pressing a button when passing a check point, for example. This is often done not only during competition but also during practice. However, this method requires an operation of reading a lap time by pressing a button, and there is an inconvenience that these operations must be performed while running.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and is provided with a required portable terminal.
It is another object of the present invention to provide a lap time that is automatically measured and displayed without passing a button or the like when a check point is passed, and at the same time, the time is synthesized and output.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a transmitter and a portable terminal which are fixedly installed and emit a weak radio wave, and wherein the portable terminal is connected to the transmitter. A receiving unit that receives radio waves, a clock unit, a control unit that records the time from the clock unit in a data storage area with a signal from the receiving unit and outputs the recorded data, and data from the control unit. A timekeeping system includes a sound output unit for synthesizing and outputting a sound based on the data, and a display unit for displaying time based on data from the control unit.

[0005]

As described above, in the timekeeping system according to the present invention, a weak radio wave is always emitted from the fixedly installed transmitter. When the portable terminal passes in front of the transmitter, a radio wave from the transmitter is received by a receiver built in the portable terminal. The portable terminal has a built-in clock unit. A time signal is extracted from the clock unit based on the signal from the receiving unit, and this time is temporarily recorded in a data storage area, synthesized and output as voice, and displayed on a display unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a timekeeping system according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a main part of an embodiment of a timing system according to the present invention. In the figure,
Reference numeral 1 denotes a transmitter that oscillates a high-frequency signal of a required frequency and transmits the signal with a weak radio wave using a directional antenna or the like. Reference numeral 2 denotes a portable terminal, which is formed into a shape like a wristwatch, for example, so that even if a track and field runner or the like carries it, it hardly interferes with the game. Reference numeral 3 denotes a receiving unit built in the portable terminal 2, which receives a radio wave from the transmitter 1 and outputs a signal when the intensity of the input signal is higher than a required level. Reference numeral 4 denotes a clock unit. Reference numeral 5 denotes a control unit which reads out the time from the clock unit 4 based on the signal from the receiving unit 3 and records it in the data storage unit 6, synthesizes it with an audio signal based on this data, and outputs it. And output it. The data storage unit 6 is, for example, a RAM (rewritable memory). Reference numeral 7 denotes an audio output unit which outputs audio according to an audio signal from the control unit 5. Reference numeral 8 denotes a display unit which displays time on a liquid crystal display panel or the like according to a display signal from the control unit 5. Reference numeral 9 denotes an input / output unit which outputs data read from the data storage unit 6 via a required input / output terminal to the outside, or inputs data to be written to the data storage unit 6 from the outside.

Next, the operation of the timekeeping system according to the present invention will be described with reference to the layout diagram of FIG. Reference numeral 11 in FIG. 2 denotes a track for athletics, for example, a track or a marathon. Reference numeral 12 is a check point for measuring a lap time. The transmitter 1 is installed beside the runway 11 and emits a weak radio wave by a directional antenna or the like so as to be propagated toward the check point 12 within the area 13. The runner carrying the portable terminal 2 runs as shown by the arrow, and
When entering 13, the radio wave from the transmitter 1 is transmitted to the portable terminal 2
Is received by the built-in receiving unit 3. The receiving section 3 outputs a signal when the intensity of the input radio wave reaches a required level.
The signal from the receiving unit 3 is input to the control unit 5, and in response to the input, the control unit 5 reads the time ticked by the clock unit 4 and records it in the data storage unit 6. Simultaneously with the recording, the signal is synthesized with an audio signal and output to the audio output unit 7, and the time is told by sound using a small speaker or the like. The time is generated as a display signal and output to the display unit 8. It is displayed on a display panel or the like. The data storage unit 6 records the input data sequentially and holds the recorded data until a required data erasing operation is performed.

When the lap time is examined after the competition to check the pace distribution, a personal computer device or the like is connected to the input / output terminal of the portable terminal 2 and the necessary operation is performed. Since the stored data is read out and sent to an external device via the input / output unit 9, for example, if the track 11 is a ground track, a list of lap times for each lap can be displayed. is there.

In addition, a target value of the lap time is previously written in the portable terminal 2, and when passing the check point,
The difference from the target lap time can be output by voice. In this case, the data of the target lap time is input from an external device via the input / output unit 9 and recorded in the data storage unit 6. Then, in response to a signal from the receiving unit 3 at the time of passing the checkpoint, the control unit 5 causes the clock unit 4
Then, a difference between the predetermined time and the target time read from the data storage unit 6 is calculated and combined with an audio signal, and the audio output unit 7 outputs an audio signal such as "the delay is XX seconds". In this case, the data input of the target lap time may be performed by providing a numeric input function in the portable terminal 2 and inputting it by key operation or the like.

[0010]

As described above, according to the timekeeping system of the present invention, it is not necessary to perform a button operation or the like when it is desired to know the lap time during a competition, so that the burden on the runner is reduced and the time is measured. Since the lap time is output by voice, it is possible to eliminate the fear of missing the lap time. In addition, since the lap time during running can be displayed at a time after the end of the competition, the present invention is also effective when, for example, studying the pace distribution at the time of training or the like.
