2. Description of the Related Art Conventionally, in marathon competitions, a unique identification number (ID code) possessed by a runner is communicated using a non-contact communication means such as radio waves via an assigned transponder (ID code tag). The interrogator sends the received identification number to the host computer. The host computer is built with an automatic timing system that determines the runner's ranking and goal time.

An example of such a timekeeping device is Japanese Patent Laid-Open No. 5-1.
No. 72, column 15, line 15 to column 16, line 22 and FIG. 1.

[0004]

However, the conventional automatic timekeeping system used for marathons and the like has a problem in that it has a large scale in terms of equipment and system and cannot be used in ordinary practice.

Further, since the radio wave radiated in a curtain shape from the interrogator has a certain width instead of a line, there is a problem that erroneous measurement such as double measurement is performed.

Further, in order to prevent the identification number returned from the responder from overlapping with other runners, there is a problem that the runners must be arranged in a line by a gate or the like.

Therefore, the present invention is to solve such a problem, and to provide a time measuring device capable of performing automatic measurement with a simple structure and being able to see one's own measurement time during competition. It is intended.

Another object of the present invention is to provide a timing device capable of automatically measuring a plurality of runners without providing a gate or the like by eliminating the reply from the responder.

Another object of the present invention is to provide a time measuring device which can measure the net time without a handicap even at the rear start.

[0019]

BEST MODE FOR CARRYING OUT THE INVENTION The timing device of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the clock device of the present invention. In the figure, a RAM 1 is a memory for storing a clocked time (measured time) and the like (information storage means, command storage means, command code storage means). Further, a ROM 2 for a program, a time counter for counting the measurement time, an input / output port, an arithmetic unit 3 including an LCD (display) driver, an arithmetic circuit, and the like.
(Time measuring means, comparison means, control means), display 4 for displaying command code and time count, oscillator 5 made of crystal, oscillator 5 is oscillated and frequency-divided to generate a reference signal necessary for measurement and the like. The frequency dividing circuit 6, a plurality of switches 7 (external operating members) connected to the input port of the arithmetic unit 3, and a sounding unit 8 connected to the output port of the arithmetic unit 3 and outputting an alarm with a buzzer or the like. The wireless power supply unit 10 includes a coil 9 serving as an antenna, a tuning capacitor, a power supply capacitor, and the like.
When the antenna receives an electromagnetic wave (power source energy) from the outside, the energy is stored in the power source capacitor.
The power supply capacitor drives the waveform shaping section 11. The synchronizing signal and the command signal following the electromagnetic wave are converted into rectangular waves by the waveform shaping section 11 and output to the computing section 3. The calculation unit 3 synchronizes with the received synchronization signal and determines the subsequent command signal. It is configured to start / stop the time measuring means or store the measurement data of the time measuring means in the RAM 1 when it is determined to be the designated command signal.

The arithmetic unit 3 has a central processing unit (CPU), and a program for controlling the central processing unit is written in the ROM 2. In addition, RAM1, ROM2,
The arithmetic unit 3 and the frequency dividing circuit 6 are composed of a one-chip microcomputer 12.

Next, a method of using the timekeeping device having this structure will be outlined.

First, as an example, a lap is measured every 400 m in a 1500 m competition on a 400 m track. A carpet-shaped transmitting antenna is installed at the start and finish lines, and this antenna is connected to the transmitting device. The transmitting antenna has a width of 50 cm so that the timing device can reliably receive the signal. The transmitter is an electromagnetic wave (30ms),
Sync signal + command signal (10 ms) and blank (10 m
It is transmitted in the cycle of s). The command code signals of the embodiment are start: 11, lap: 12, stop: 14. The timekeeping device is housed in a wristwatch and worn on the arm of the user.

At the start point, an electromagnetic wave and a start command code signal (: 11) are transmitted a plurality of times from the transmitter in conjunction with the start sound of the pistol. The timekeeping device is coil 9
When the electromagnetic wave is received, the wireless power supply unit 10 stores energy, operates the waveform shaping unit 11, converts the received signal into a digital signal, and sends the digital signal to the calculation unit 3. The arithmetic unit 3 detects the sync signal and, when the sync signal is detected, processes the subsequent command code signal to determine what command has been received. In this case, a start command is determined and the time measuring means is started to start the measurement and display the data of the time measuring means on the display unit 4. The transmitting device provided at the start line changes the command code signal to lap (: 12) when the athlete finishes passing through the transmitting antenna. When the command code signal is set to lap, electromagnetic waves and command signal transmission are always repeatedly output. When the competitor goes around the track and returns to the start line, the timing device operates the waveform shaping section 11 in the same manner as the coil 9 receives the electromagnetic wave, converts the received signal into a digital signal, and causes the calculation section 3 to perform the calculation. send. Arithmetic unit 3
Similarly determines which command has been received. In this case, it is determined to be a lap command, and the time data of the time measuring means is RA.
It is stored in M1 and displayed on the display unit 4. This operation is repeated 3 times up to 1200 m. The stop line code signal (: 14) is transmitted by the finish line transmitter. When the competitor passes the finish line, the timing device operates the waveform shaping section 11 in the same manner as receiving the electromagnetic wave with the coil 9, converts the received signal into a digital signal and sends it to the calculation section 3. The calculation unit 3 similarly determines what command has been received. In this case, a stop command is determined and the time measuring means is stopped and the data of the time measuring means is stored in the RAM 1. Then, it is also displayed on the display unit 4.

Although the transmitting device has been described with respect to the protocol for transmitting the electromagnetic wave, the synchronizing signal and the command code signal, the transmitting device is designed to transmit only the electromagnetic wave and the arithmetic unit 3 determines whether the wireless power source unit 10 has accumulated energy. If it is configured such that it is determined that the measurement point has been passed, the waveform shaping section 1
1 is deleted, and the configuration including the transmitting device can be further simplified.

Further, although the electromagnetic wave (power source energy) is received from the transmitter and operated, the electromagnetic wave may not be transmitted by supplying power from the power source of the arithmetic unit only during measurement.

According to the above-mentioned structure, the user can measure the time without worrying about the timing of the switch operation, so that the balance is not lost for the time measurement and the time measurement is not taken into consideration. You can concentrate on training.

Further, since the time measured by oneself during the competition is displayed on the display every moment, one's own time can be known at any time.

Next, the internal structure of the RAM 1 which is the information storage means will be described.

FIG. 2 is an internal configuration diagram (memory map) showing the main part of the RAM 1. Memory address is PAGE, HIG
It is selected by H and LOW, and LOW consists of 4 bits.
Address names are shown on the right side for ease of explanation. This figure shows an example of a state in the middle of measurement.

First, in the integrated data address, integrated time data (0: 00: 34: 56) from the start of measurement is stored. The integrated data address serves as a clock counter (time measuring means). The work 1 and work 2 addresses are general-purpose memories that are temporarily used for calculations and the like. The work 3 address is a memory that counts down the timer. The timer time (5 seconds) set in the work 3 address is stored in the timer memory address. Start 1
Start command data (11), start 2 at address
Start command data (21) for address, lap command data (12) for lap 1 address, lap command data (22) for lap 2 address, stop command data (14) for stop 1 address, stop 2 address. Stop command data (24) is stored in the LO
W = 7 Address flag = 1 is selected. That is, the command data at the start 1, lap 1, and stop 1 addresses are valid, and the command data at the start 2, lap 2, and stop 2 addresses are invalid. One command code is externally selected from two identical function codes. A plurality of command codes having the same function such as Start 1 and Start 2 are provided in order to prevent malfunction due to traversing a transmitting device provided by another person in a truck or the like, and to use a command code dedicated to them.

Data addresses 1 to n store the data of the integrated data address at the time measurement, but nothing is stored yet.

The data from the start 1 address to the stop 2 address are displayed on the display 4 and can be set and corrected by the switch 7.

FIG. 3 is a flow chart for explaining a reception process 1 (first embodiment) for performing a command data reception process of the clock device of the present invention.

First, the individual steps and their operations will be described in a general manner along the flow. In the figure, in step 21, the waveform shaping section 11 is operated by the electromagnetic wave, and it is determined whether a subsequent synchronizing signal is received.
It is. Step 22 is "timer end?" For judging whether the timer set in step 32 has ended. Step 23 is "F = 0" which resets the flag.
Step 24 is "command received?" For judging whether or not there is a command signal following the synchronization signal. Step 25 determines whether the flag is set in Step 33 "
F = 1? In step 26, it is determined whether the received command signal is a start command "start? Step 27 is a "start processing" for starting the time measuring means and displaying the data of the time measuring means on the display 4. Step 28 is for judging whether the received command signal is a lap command ". Rap? Step 29 stores the measurement time of the time measuring means in the RAM 1,
This is the "lap processing" displayed on the display unit 4. Step 30 is "stop?" For judging whether the received command signal is a stop command. Step 31 is a "stop processing" in which the time measuring means is stopped, the data of the time measuring means is stored in the RAM 1 and displayed on the display unit 4. Step 32 sets the data of the timer memory address in FIG. 2 to the work 3 address and starts the timer processing. "
"Timer start". Step 33 is "F = 1" for setting the flag. Step 34 is "End" for ending the reception process 1.

Next, the actual flow of the flowchart of FIG. 3 will be described. The command signal of the embodiment is start: 11,
Lap: 12 and stop: 14. In addition, 400m
An example of measuring laps every 400m in a 1,500m competition on a track will be described. A carpet-shaped transmitting antenna is installed at the start and finish lines, and this antenna is connected to the transmitting device. In the state where the flag is reset, the electromagnetic wave, the synchronization signal and the start command sent with the pistol sound at the start point are set in Step 21.
Step 2
Proceed to steps 4 and 25. Since the flag is not set in step 25, the process proceeds to step 26. Here step 2
It is determined from 6 that the current command is the start command, and the time measuring means is started in step 27. Then, in step 32, the 5-second timer is started. Further, in step 33, the flag is set and the processing is ended.

The width of the transmitting antenna is 50 cm, and the width of the receiving area is wider. Further, when the command signal transmitted in the cycle of 50 ms is received again at the start point, it is determined to be received in step 21, but it is determined in step 25 that the flag is set, and the process returns to step 21. When it is separated from the transmitting antenna, it is considered that there is no reception in step 21, and it is determined in step 22 whether the timer set in step 32 has expired. When the timer expires, the flag is reset in step 23.

When the athlete finishes passing the transmitting antenna at the start point, the start point is changed to the lap measurement point. The command signal output from the transmitter is changed from the start command to the wrap command. When the transmitter sets the wrap command, the electromagnetic wave, the synchronization signal, and the wrap command are repeatedly output.

When the competitor makes one circuit around the track and returns to the lap line (at a point of 400 m), the step 2 is repeated.
8 and 29 are executed and the data of the integrated data address is R
The data is stored in AM1 and displayed on the display 4, and steps 32 and 33 are executed. Similarly, the same processing is performed up to three laps (1200 m point). An electromagnetic wave, a synchronizing signal, and a stop command are constantly repeatedly output from a transmitting device provided at the finish line (1500 m point).
When the athlete passes through the transmitting antenna on the finish line, steps 30 and 31 are executed, the data of the integrated data address is stored in the RAM 1 as the finish data, and displayed on the display 4 to execute steps 32 and 33. .

That is, when steps 27, 29 and 31 are executed, the 5-second timer is set in step 32,
For the next 5 seconds, even if the command signal is received, it is ignored. Therefore, the command signal is processed only once while passing through the transmitting antenna.

In the embodiment, the step 32 is explained as 5 seconds, but the present invention is not limited to this. It is 2 seconds for short distance measurement and 30 seconds for long distance measurement. Alternatively, the time may be set more directly or the time itself may be directly set. If it can be changed according to the measurement conditions, erroneous measurement can be further prevented.

According to the above-mentioned structure, a plurality of persons can be automatically measured at the same time, and the elapsed time which changes from moment to moment and the measured lap time and split time are displayed.
The competitor can know the time required.

Further, even if the transmission width of the transmitting antenna is wide, the command processing is performed only once, so that a highly reliable time measuring device can be provided.

FIG. 4 is a flow chart for explaining a reception process 2 (second mode) for performing the command signal reception process of the timer according to the present invention. Time measurement conditions for explanation are the same as those in FIG. Further, description of the same processing as that in FIG. 3 is omitted.

Step 41 is "same?" For comparing the command signal processed last time and the command signal received this time. Step 42 is "reception code storage" in which which processing of steps 27, 29 and 31 has been executed is stored in the RAM 1 as a code.

In the start preparation system, the time measuring means is in a stopped state and the integrated data address is in a reset state (reset display). In Step 25, the flag is in the reset state, and Step 21 and Step 2
Repeat 3 When it is detected in step 24 that the start command sent together with the pistol sound has received any command, the process proceeds to step 41. Here, the control code received last time is stop (: 14), the process proceeds to step 26, and it is determined that the command of this time is the start command (: 11), and the time measuring means is started by step 27. Further, in step 42, the start command code (: 11) is stored. Then, in step 32, the 5-second timer is started. Step 3
By 3, the flag is set and the process ends. Since the start command signal (: 11) is continuously transmitted from the transmitting antenna, it is determined in step 41 that they are the same in the second reception, and the process proceeds to step 25. Since step 23 has not been executed in step 25, the process proceeds to step 21.

That is, when the same command is received, the time set in step 32 is not accepted. When different commands are issued, the command process is immediately executed.

According to the above-mentioned structure, even if the receiving area of the transmitting antenna is wide, the receiving process is performed only once, so that a highly reliable time measuring device can be provided.

FIG. 5 is a flow chart for explaining a reception process 3 (third embodiment) for performing the reception process of the command signal of the timer according to the present invention. Time measurement conditions for explanation are the same as those in FIG. Further, description of the same processing as that in FIG. 3 is omitted.

Step 51 is an electromagnetic wave (power source energy)
Is “energy received?”
This is to determine whether or not the voltage of the wireless power supply unit 10 is present. Step 52 is "start state?" For judging whether the time measuring means is measuring. Step 53 is "stop SW?" For determining whether or not the stop switch for manually stopping the time measuring means is pressed. Step 54
Is the "stop processing" that stops the time measuring means.

Next, the actual flow of the flowchart of FIG. 5 will be described. The time measuring means is stopped and the integrated data address is reset (reset display)
It has become. When the electromagnetic wave sent together with the pistol sound is detected at the start point, the process proceeds to step 25. Since the flag is not set in step 25, step 5
Proceed to 2. Here, the time measuring means is determined to be in the stopped state, and the time measuring means is started in step 27. Then, in step 32, the 5-second timer is started. Further, in step 33, the flag is set and the processing is ended.

When it is judged again at step 51 that the signal is received at the start point, it is judged at step 25 that the flag is set, and the process returns to step 21. When it is separated from the transmitting antenna, it is considered that there is no reception in step 21, and it is determined in step 22 whether the timer set in step 32 has expired. When the timer expires, the flag is reset in step 23.

When the competitor makes one circuit around the track and returns to the lap line (at a point of 400 m), step 5 is repeated.
1 and 25 are executed, the time measuring means is determined to be in the measuring state in step 52, the data of the integrated data address is stored in the RAM 1 in step 29, and the data is displayed on the display 4, and steps 32 and 33 are executed. It Similarly, the same processing is performed up to three laps (1200 m point). When step 51 detects an electromagnetic wave from the transmitter provided at the finish line (1500 m point), step 29 is executed and the data of the integrated data address is read by R.
The data is stored in AM1 and displayed on the display 4, and steps 32 and 33 are executed.

When the athlete presses the stop switch of the timing device after passing the finish line, the time measuring means stops the measurement in step 54 and the final lap time is displayed as the finish time. That is,
The time when the stop switch is pressed is not measured (stored). Therefore, the start, split / lap and finish data are automatically measured only by the presence or absence of specific electromagnetic energy.

According to the above-mentioned configuration, even if the transmitting device and the receiving system are simplified and the receiving area by the transmitting antenna is wide, the receiving process is performed only once, so that a highly reliable time measuring device can be provided.

[0056]

As described above, the timing device of the present invention has the following effects.

According to the first and third aspects of the present invention, since the time measurement is automatically performed, it is possible to concentrate on the competition and training.

Moreover, once the command processing is performed, the next command processing is not performed for a predetermined time, so that erroneous measurement can be prevented.

According to the second and third aspects of the present invention, even if the measurement points are adjacent to each other, command processing is performed only once at the same measurement point, so that erroneous measurement can be prevented.

According to the inventions of claims 4 and 5, since the command code only for oneself can be set, it is possible to prevent erroneous measurement due to the command codes of other people.
