Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile body management system capable of measuring the travel time of individual mobile bodies moving on a predetermined course and determining the arrival order in a marathon, a rally, etc. Regarding mobile devices.

[0002]

2. Description of the Related Art Conventionally, in a marathon, a rally or the like, when a runner or a car (hereinafter referred to as a moving body) is used to measure the running time and the elapsed time during the running, and the result and the arrival order are recorded, the following is generally used. It was done by either method. (1) First method: The time is measured and recorded artificially from the outside. (2) Second method: Regarding time measurement, the running time is measured by artificially instructing each of the moving bodies to start and stop the time measurement. (3) Third method: For time measurement, a transmitter is attached to each moving body, and the measuring instrument installed at the goal point receives the transmission signal when each moving body makes a goal, and the goal is set. Recognize and measure the running time by the difference from the preset start time.

[0003]

However, the above-mentioned first method has the following drawbacks. A lot of manpower and equipment are required to measure each moving body from the outside. It takes a lot of time to record information such as measurement results of individual moving bodies. It takes a lot of time to collect the recorded information. Since the arrival order is artificially determined for each moving body, an error is likely to occur, and particularly when the number of moving bodies is large, it takes a long time for each moving body to know the arrival order. When a considerable number of moving bodies travel, the start timings do not coincide, and the measurement results deviate from the actual running time.

The second method has the following drawbacks. If the moving body forgets to start or end the timekeeping operation, the measurement cannot be performed. When inputting the measurement results of individual moving bodies to various data processing devices, it takes time to input the data. Since the arrival order is artificially determined for each moving body, an error is likely to occur, and particularly when the number of moving bodies is large, it takes a long time for each moving body to know the arrival order.

Furthermore, the third method has the following drawbacks. It is not possible to measure the elapsed time at each point while driving. It is necessary to accurately match the start times of the measuring instruments installed at the goal points. Each moving body cannot know its own measurement result in real time. Since the arrival order is artificially determined for each moving body, an error is likely to occur, and particularly when the number of moving bodies is large, it takes a long time for each moving body to know the arrival order. When a considerable number of moving bodies travel, the start timings do not coincide, and the measurement results deviate from the actual running time.

After all, according to the conventional method, it is not easy to measure the traveling time of the moving body accurately and finely because the measurement and recording work requires manual work, and the measurement result of each moving body is not easy. And there was a problem that the arrival order could not be known quickly.

The present invention has been made under such a background, and it is possible to accurately and finely measure the traveling time of each moving body without manpower, and the individual moving body can obtain the measurement result and arrival. It is an object of the present invention to provide a mobile management system and a mobile device that can quickly know the ranking.

[0029] (4) Configuration and operation of the mobile device D ₁ to D _m Next, the configuration of the mobile device D ₁ to D _m. FIG. 9 is a block diagram showing the configuration of an arbitrary mobile device D _k . As shown in this figure, the mobile device D _k includes a control unit 1d and a timer 2
d, a memory section 3d and a display section 4d. The control unit 1d includes a receiver (including a filter) 12 that receives a radio signal via the radio signal reception antenna 11d.

And a unique information code memory 32d.
In the memory 31d, passing time at each intermediate point timed by the timer 2d and running time of the entire course, identification information (position code, etc.) of each point received from each of the wireless transmitters B _{1 to} B _n-1 , And the arrival order received from the wireless transceiver C is recorded.

It is composed of a bar code display section 42d for displaying a code.

Next, the operation of the mobile device D _k will be described with reference to the flow charts shown in FIGS. First, when the power is turned on (see FIG. 10), the unique code of each mobile unit _k is displayed on both the digital display section 41 d and the bar code display section 42 d as shown in, for example, FIG. 18 (a). Step Sc1). When a wireless signal is received from the wireless transceiver A at the start point (step Sc2), the received signal is identified by the signal identifying circuit 13d (step Sc3). Next, it is determined whether the ID code included in the received signal and the ID code stored in the unique information code memory 32d match (step Sc4). If they do not match, the received signal is not captured because it is not the wireless signal of this system.

In this case, since the ID codes of both are the same, the determination result of step Sc4 is "Yes", and the process proceeds to step Sc5. In step Sc5, the received signal is taken in and the unique code displayed in step Sc1 is erased. Then, it is determined whether or not the received signal includes the reset code and the timer ON code (step Sc6).

In this case, since the transmission signal of the wireless transceiver A includes the reset code and the timer ON code, the determination result of step Sc6 becomes "Yes",
It proceeds to step Sc7. In step Sc7, it is further determined whether or not the same code as the received code is already stored in the memory 31d, that is, whether or not the received signal is not the first received signal. Here, if the received signal is not the first received signal, the received signal is discarded (step Sc23).

In this case, if the received signal is received for the first time, the determination result of step Sc7 is "No", and the reset code and the timer ON code included in this received signal are stored in the memory 31d. (Step Sc8). Then, the timer 2d and the memory 31d are reset by the reset code (step Sc9), and the receiver 12d is disabled to avoid receiving the same signal. In addition, the timer is ON
The code causes the timer 2d to start the counting operation (step Sc10).

Next, when the runner reaches the first waypoint on the course and the mobile device D _{k of the} runner approaches the radio transmitter B ₁ within a predetermined distance, the above-mentioned step Sc2 is performed again.
In (see FIG. 10), the wireless signal transmitted from the wireless transmitter B ₁ is received. This received signal is identified by the signal identification circuit 1
If the ID code included in the received signal and the ID code stored in the unique information code memory 32d match (step Sc4), the received signal is fetched. The above is the same as the operation at the start point described above.

In this case, since the radio transmitter B ₁ does not include the reset code and the timer ON code, the result of the determination in step Sc6 is "No", and the process proceeds to step Sc11 (see FIG. 11). Step Sc1
At 1, it is determined whether the received signal includes the position code. In this case, since the position code is included in the wireless signal of the wireless transmitter B ₁ , the determination result here is “Y
es ”and the process proceeds to step Sc12. Step Sc
12, the same code as the received code is stored in the memory 31.
It is judged whether or not it is already stored in d, that is, whether or not this received signal is the first received signal. Here, if the received signal is not the first received signal,
This received signal is discarded (step Sc24).

In this case, assuming that the received signal is received for the first time, the received code is stored in the memory 3
1d (step Sc13), the position code included in this reception code and the timer 2d at this time.
It is stored in the memory 31d in association with the measured time value of (step Sc14). Further, for example, as shown in FIG. 18B, the measured value of the timer 2d at this time is displayed on the digital display portion 41d.

In this way, the mobile device D _k repeats the same operation as at the first waypoint described above each time it reaches each waypoint thereafter, and passes through the position code received at each waypoint and each waypoint. The time count value of the timer 2d and the time value are sequentially stored in the memory 31d.

When the runner reaches the goal point on the course and the runner's mobile device D _k approaches the wireless transmitter B _n within a predetermined distance, the above-mentioned step Sc2 is performed again.
In FIG. 10 (see FIG. 10), the wireless transmitter B _n sends the timer O
A wireless signal including an FF code is received. Then, after going through steps Sc3 to Sc6 and Sc11, step Sc1
5 (see FIG. 11). In step Sc15, it is determined whether or not the received signal includes the timer OFF code. In this case, the determination result of step Sc15 is “Yes
s ”, and the process proceeds to step Sc16. Step Sc1
6, the same code as the received code is stored in the memory 31d.
It is determined whether or not it has already been stored in, that is, whether or not this received signal has not been received for the first time. Here, if the received signal is not the first received signal,
This received signal is discarded (step Sc25).

In this case, if the received signal is received for the first time, the received code is stored in the memory 31d.
(Step Sc13), the system ID code and the unique code of the mobile device D _k stored in the unique information code memory 32d are read (step Sc17). Then, the read code is transmitted to the transmitter 1
7d (step Sc18), and the signal is sent from the transmitter 17d via the wireless transmission antenna 16d (step Sc19).

The radio signal at this time is, for example, as shown in FIG. 13, an ST code indicating the start of the signal and a system I
It is transmitted in a signal format including a D code, a unique code of the mobile device D _k , and an EN code indicating the end of the signal. Thereby, the identification information unique to each of the mobile devices D _{1 to} D _m is transmitted to the wireless transceiver C.

Then, the timer 2d stops the timing operation of the timer 2d by the timer OFF code (step Sc20), stores the timing value at this time in the memory 2d (step Sc21), and avoids receiving the same signal by the receiver 12d. Is disabled (step Sc22).

Next, when the operator operates a predetermined display section control switch, the mobile unit D _k performs the manual instruction operation process shown in FIG. 12 (a). That is, when the display instruction signal is supplied according to this operation, the control circuit 15d first determines whether or not the receiver 12d is in the disabled state (step Sc31). Then, when it is confirmed that the receiver 12d is in the disabled state, the arrival order (obtained by receiving from the wireless transceiver C) and the running time stored in the memory 2d are determined by, for example, FIG. ), The digital display section 41d and the bar code display section 42d are displayed.
Display on both sides. Further, the position code and the passage time of each intermediate point are sequentially displayed as bar codes on the bar code display section 42d as shown in FIG. 18D (step Sc32).

Next, when the operator operates a predetermined reset switch, the mobile unit D _k performs the manual reset process shown in FIG. 12 (b). That is, when the reset signal is supplied in response to this operation, the control circuit 15d first performs the manual instruction operation process and the receiver 12d.
It is determined whether or not is disabled (step Sc41). When the manual instruction operation process has already been performed and it is confirmed that the receiver 12d is in the disabled state, the disabled state of the receiver 12d is released, and then the memory 2d is reset (step Sc).
42). Then, the power of the mobile device D _k is turned off.

(5) Configuration and Operation of Radio Transceiver C Next, the radio transceiver C installed at the finish point of the course
The configuration of will be described. FIG. 14 is a block diagram showing the configuration of the wireless transceiver C. As shown in this figure, the wireless transceiver C is a radio signal receiving antenna 1c and receiver 2c receives a radio signal from the mobile device D ₁ to D _m in a goal point, the signal discrimination circuit 3c for identifying the received signal
And a signal processing circuit 4c for determining the reception order of received signals
When, a signal generating circuit 5c for generating the ranking code for notifying a ranking for each mobile device D ₁ to D _m, I system
A unique information code memory 6c the D code is stored, the memory 7c received signal is stored, a transmitter 8c and the radio signal transmitting antenna 9c for wirelessly transmitting the transmission code to the mobile station D ₁ to D _m, the Control circuit 10c for controlling each part
It consists of and.

Next, the operation of the wireless transceiver C will be described with reference to the flowchart shown in FIG. First, when the power is turned on, the radio signals transmitted from the mobile units D _{1 to} D _m are received (step Sd1), and these received signals are identified by the signal identification circuit 13d (step Sd).
2). Next, it is determined whether the ID code included in each received signal and the ID code stored in the unique information code memory 6c match (step Sd3).
If they do not match, the received signal is not captured because it is not the wireless signal of this system.

In this case, since the ID codes of both are the same, the determination result of step Sd3 is "Yes", and the process proceeds to step Sd4. In step Sd4, it is determined whether the same code as the received code is already stored in the memory 9c, that is, whether the received signal is not the first received signal. If the received signal is not the one received for the first time, the received signal is discarded (step Sd10).

[0049] In this case, if it is assumed that the received signal is first received, the determination in step Sd4 becomes "No", takes in the received signal to the signal processing circuit 4c, the mobile station D ₁ to D _The reception order is determined for the received signal from _m (step Sd5). Then, each received signal is stored in the memory 7c together with its reception order (step Sd6). Then, in the signal generating circuit 5c, and adds information indicating a reception ranking unique code for each mobile device D ₁ to D _m included in the received signal (step Sd7), and sends to the transmitter 8c this as transmission code (Step Sd8).
Then, wirelessly transmits the transmission code from the wireless transmission antennas 9c to each mobile unit D ₁ to D _m (step Sd9).

The radio signal at this time is, for example, as shown in FIG. 16, an ST code indicating the start of the signal and the system I
It is transmitted by a signal format including a D code, a unique code of each mobile device D _k , a rank code indicating a reception rank, and an EN code indicating the end of a signal. As a result, the mobile stations D _{1 to} D _m are notified of the reception order, that is, the arrival order at the goal point.

(6) Overall Operation Next, the overall operation of this system will be described. First, at the start point, when the wireless transmitter A is supplied with a start instruction signal for instructing a start, the wireless transmitter A transmits a wireless signal including a reset code and a timer ON code. At this time, as each runner starts traveling, each of the mobile devices D _{1 to} D _m receives the radio signal transmitted from the radio transmitter A, and thereby the timers 2 incorporated in each of them simultaneously.
The timing operation of d is started.

In this case, at the timing when each runner passes the start line at the start point, each mobile unit D ₁ ~
If D _m receives the radio signal transmitted from the radio transmitter A, it is possible to start timekeeping in accordance with the timing of each start. As described above, a method for receiving a radio signal at the start point with good timing will be described later in detail, as in the case of each intermediate point and goal point described later.

Now, each runner starts running, and the radio transmitter B installed at the first intermediate point on the way in the course.
_When passing in front of ₁ (that is, when approaching within a predetermined distance), each of the mobile devices D _{1 to} D _m receives a radio signal including the position code transmitted by the wireless transmitter B ₁ , and the position code and this time are received. The measured value of the timer 2d is recorded in association with.

In this way, at each subsequent intermediate point, the mobile stations D _{1 to} D _m repeat the same operation as the first intermediate point described above, and the position codes transmitted by the respective wireless transmitters B _{1 to} B _n-1. And the measured value of the timer 2d when passing in front of these are sequentially recorded.

Then, each runner reaches the goal point,
When passing in front of the wireless transmitter B _n installed at the goal point (that is, when approaching within a predetermined distance), the mobile devices D ₁ to
D _m receives the wireless signal including the timer OFF code sent from the wireless transmitter B _n , and stops the timer 2d for counting time. Then, the measured value of the timer 2d at this time is recorded as the running time.

Next, each of the mobile units D _{1 to} D _m sends a radio signal including its own unique code to the radio transceiver C. The wireless transceiver C receives this and determines the order of arrival of each of the mobile units D _{1 to} D _{m at} the goal point according to the reception order.
Then, the wireless transmitter / receiver C pairs the arrival order of each of the mobile devices D _{1 to} D _m and these unique codes as a pair and sends them out by a wireless signal. Each of the mobile units D _{1 to} D _m identifies its arrival order by receiving this radio signal, and displays this arrival order on the display unit 4 d together with the recorded running time.

Further, each of the mobile units D _{1 to} D _m sequentially displays the recorded contents as a bar code in response to a predetermined button operation by the operator. Then, this bar code is sequentially read by the bar code sensor 11, and each mobile device D ₁ ...
The recorded contents of D _m are collected by the personal computer 12 and subjected to various data processing.

(7) Mode of Radio Transmission by Each Radio Transmitter In this embodiment, the mobile stations D _{1 to} D _m are set to the start point, each intermediate point, and the goal by adopting the following method, for example. The wireless signal of each wireless transmitter can be received with good timing when passing through the point. The radio signals transmitted by each radio transmitter are weak radio waves,
The detection is made possible only when each of the mobile devices D _{1 to} D _m passes in front of the wireless transmission antenna of each wireless transmitter. As shown in FIG. 17, the radio transmission antenna of each radio transmitter is configured by the transmission antenna 21 having sharp directivity, and the radio wave is prevented so that the mobile device D _k does not receive the radio wave before the runner reaches each passage point. The shield 31 is provided. Each mobile device D ₁ with a photo coupler installed at each passing point
The passage of ~ D _m is detected, and each radio transmitter controls ON / OFF of emission of radio waves according to the detection result. If the wireless transmitter A can change the radio wave emission direction at the start point, each of the mobile devices D _{1 to} D _m can be changed.
It is possible to select to start the timing by all at once or to start it at the timing when each of the mobile units D _{1 to} D _m passes the start point.

(8) Effects of this Embodiment As described above, according to this embodiment, the following effects can be obtained. a) Since the start of timing at the start and the timing stop at the goal are controlled by wireless signals, the runner does not need to perform the timing operation. As a result, it is possible to prevent forgetting to count the time and to reliably measure the running time. b) Since each individual runner can start timing at the timing of passing the start point, the timing is started at the same timing as the actual running start of each runner.
It is possible to measure the actual running time accurately without any deviation from the actual running time. c) Each runner can immediately know his / her arrival order at the time of goal without any manual intervention.

D) Since the passing time at each intermediate point of the course is recorded, each runner can know not only the running time of the entire course but also the passing time at each point on the way. e) Since the mobile equipment of each runner records the transit time at each intermediate point of the course, it is not necessary to provide a special transmission line or the like to collect these recording results from each point. f) By using weak radio waves for wireless transmission of the wireless transmitter at each point, interference with others can be avoided.

G) By reading the bar-code-displayed record information by the bar-code sensor 11, the record information can be input to the personal computer 12 quickly and easily. h) Since the recording results for each runner can be quickly captured in the personal computer 12, the recording results and arrival order for all runners can be known in a short time. i) Since the unique code of each runner can be swiftly read by the bar code sensor 11, it is possible to efficiently perform registration work such as registration before the start of the competition.

J) The bar code display can be easily changed by changing the data to be displayed. k) Since the displayed information can be erased manually,
Confidentiality can be maintained for each runner. l) Since the wireless signal can be received only once at each point, erroneous reception can be prevented.

(9) Application Example In the above-mentioned embodiments, the case of application to a marathon is taken as an example, but not limited to this, for example, relay race, car rally, triathlon, orienteering, ski nordic competition, etc. It can also be applied to other various competitions. In addition to such competitions, it can also be applied to, for example, entry / exit at a company or the like, management of visitors, visitors, and the like.

As described above, according to the present invention, the following effects can be obtained. (1) Since the start of timekeeping at the start point and the stop of timekeeping at the goal point are controlled by wireless signals, it is not necessary for humans to perform timekeeping operations. As a result, it is possible to prevent forgetting to count the time and to reliably measure the running time. (2) Since each mobile unit can start timing at the timing when it passes the start point, timing starts at the same timing as the actual start of traveling of each mobile unit, and there is a deviation from the actual running time. Accurate actual travel time can be measured. (3) The arrival order can be immediately notified to each mobile device at the time when the goal is reached without any manual intervention. (4) Since the passing time at each intermediate point of the course is recorded, not only the running time of the entire course but also the passing time at each point during the running can be known. (5) Since each mobile device can simultaneously start the timer operation at the start point, it is possible to measure the traveling time based on the same start timing for all mobile devices. (6) Since the record information of each mobile device can be displayed as a bar code, the record information can be input to a personal computer or the like quickly and easily by reading the bar code sensor.
