Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a block diagram of a time measurement system 1 in the present embodiment.
The time measurement system 1 includes a start pistol SP, a trigger device 2 as a trigger means, a grip switch 3 as a switch, a control device 4 as a control means, and a display panel 5.

  The start pistol SP is connected to the control device 4 and supplies a start signal to the trigger device 2 when the trigger is pulled.

  In response to the start signal from the start pistol SP, the trigger device 2 supplies the control device 4 with a trigger signal that triggers the start of time measurement.

The grip switch 3 is a manual switch having two push buttons, a first switch G and a second switch RE. The first switch G is a push button that is pressed by the timekeeper when the athlete passes the measurement point. The second switch RE is a push button that is pressed to return the count value when the timekeeper presses the first switch G too much. When the first switch G is pressed, the grip switch 3 sends a first pulse signal instructing the control device 4 to execute display information determination processing, which will be described later, and the like. When is pressed, a second pulse signal instructing the control device 4 to set the count value of an arrival order counter 45 (described later) to −1 in response thereto is transmitted.
In the present embodiment, a time measuring system having only one grip switch 3 will be described as an example. However, the present invention can also be applied to a time measuring system having a plurality of grip switches 3.

  As shown in FIG. 2, the control device 4 includes an input unit 41, a CPU (Central Processing Unit) 42, a first time counter 43, a second time counter 44, an arrival order counter 45, and a selector 46. And an output unit 47, a memory 48, and a storage unit 49.

  The input unit 41 includes a connector, a receiver, and the like. The input device 41 is connected to the trigger device 2 and the grip switch 3, and receives signals from the trigger device 2 and the grip switch 3, and transmits them to the CPU 42, the first time counter 43, the second time counter 44, and the arrival order counter 45.

The CPU 42 controls the entire control device 4 based on a program or the like stored in the storage unit 49. For example, the CPU 42 causes the selector 46 to select normal display information during normal display information determination processing described later, and interrupt display information (for example, run time and rank information corresponding thereto) during the interrupt display processing. Is determined and output to cause the selector 46 to select the interrupt display information.
The interrupt display information is information including a running time acquired by the CPU 42 in response to the first pulse signal and rank information corresponding to the running time. The running time becomes additional information displayed on the third display unit 53 of the display panel 5, and the rank information corresponding to the running time becomes rank information displayed on the second display unit 52.
Also, the normal display information is the delay (behind leader time) from the passing time of the athlete who first passed the measurement point and the number of the last competitors who passed the measuring point up to that point (the latest ranking) ). The behind leader time is additional information displayed on the third display unit 53 of the display panel 5, and the latest rank information is rank information displayed on the second display unit 52.

  In response to the trigger signal from the trigger device 2, the first time counter 43 starts time measurement, that is, counting of running time that is an elapsed time after the start. The first time counter 43 supplies the count value to the display board 5 via the output unit 47. Further, the first time counter 43 supplies the count value to the CPU 42 in response to a request from the CPU 42.

  The second time counter 44 starts counting in response to the first first pulse signal after starting the time measurement, and supplies the count value to the selector 46. The count value of the second time counter 44 indicates a delay (behind leader time) from the passing time of the player (leader) who has passed the measurement point first.

The arrival order counter 45 changes the count value under the control of the CPU 42. Specifically, when the CPU 42 receives the first pulse signal, the CPU 42 increments the count value of the arrival order counter 45, and when it receives the second pulse signal, it decrements the count value of the arrival order counter 45. The count value of the arrival order counter 45 indicates the number of competitors that have already passed the measurement point, that is, the latest ranking information.
Note that the count value of the arrival order counter 45 is decremented by −1 by the second pulse signal when, for example, the count value is corrected when the timekeeper erroneously presses the first switch G.

  The selector 46 receives the normal display information composed of the count value of the second time counter 44 and the count value of the arrival order counter 45 and the interrupt display information from the CPU 42, and the normal display information is controlled by the CPU 42. And the interrupt display information are selected, and the selected display information is supplied to the output unit 47.

  The output unit 47 includes an encoding circuit, a level conversion circuit, a driver, and the like. The output unit 47 converts information received from the first time counter 43 and the selector 46 into a format that can be received by the display board 5 and supplies the display board 5 with the information.

  The memory 48 is composed of a RAM (Random Access Memory) or the like, and serves as a work space for temporarily storing information necessary for the arithmetic processing of the CPU 42. For example, the memory 48 stores an interrupting flag indicating that interrupt display is being performed in a display information determination process described later, and N (for example, 4 seconds) that is a setting value that defines a period for displaying interrupt display information. Remember.

  The storage unit 49 includes a ROM (Read Only Memory), a nonvolatile memory, and the like, and stores a program executed by the CPU 42. For example, the storage unit 49 stores a program that defines display information determination processing described later.

Returning to FIG. 1, the display board 5 receives information supplied from the control device 4 and displays it. Specifically, as shown in FIG. 3, the display board 5 includes a first display unit 51, a second display unit 52, and a third display unit 53. Each of the first to third display units (51-53) includes a display element such as an LED, a magnetic reversal element, and a liquid crystal display element, and a display control circuit.
The first display unit 51 receives the running time counted by the first time counter 43 of the control device 4 via the output unit 47 and always displays it.
The second display unit 52 receives the order information selected by the selector 46 of the control device 4 via the output unit 47, and the normal order is the latest order, and the order corresponding to the running time is displayed during the interrupt display process. Display each.
The third display unit 53 receives the additional information selected by the selector 46 of the control device 4 via the output unit 47, and displays the behind leader time during normal times and the running time during interrupt display processing.

In the time measuring system 1 having such a configuration, the competition is started when the starter fires the start pistol SP, and time measurement is started. Each time the athlete passes the measurement point, the timekeeper presses the first switch G of the grip switch 3 to acquire the run time and rank of each athlete, and the display content of the display board 5 is updated. Is done.
Hereinafter, with reference to the flowcharts shown in FIGS. 4 and 5, the information displayed on the second display unit 52 and the third display unit 53 that is executed when the first switch G of the grip switch 3 is pressed. The procedure of the display information determination process for determining the image will be described.
In addition, about the display content of the 1st display part 51, the count value of the 1st time counter 43 is displayed irrespective of a display information determination process.

  Prior to the start of the competition, the first time counter 43, the second time counter 44, and the arrival order counter 45 are all reset, and the count values are all zero. Further, the CPU 42 secures an area for an interrupting flag in the memory 48 and sets the interrupting flag to 0. Further, the CPU 42 secures an area for storing N, which is a period for displaying the interrupt display information, in the memory 48 and stores the set value. Further, the CPU 42 controls the selector 46 to select normal display information.

When the starter fires the start pistol SP, a start signal is sent from the start pistol SP to the trigger device 2. The trigger device 2 that has received the start signal supplies the control device 4 with a trigger signal that triggers the start of time measurement. The first time counter 43 of the control device 4 that has received the trigger signal starts counting, time measurement is started, and the running time is displayed on the first display portion 51 of the display panel 5.
In addition, the competition is started by firing the start pistol SP.

As the competition progresses, each competitor reaches a measurement point (for example, 5 km point, 10 km point,..., Goal point). The timekeeper presses the first switch G of the grip switch 3 every time the athlete passes the measurement point.
When the first pulse signal generated by pressing the first switch G of the grip switch 3 is supplied to the control device 4, the input unit 41 of the control device 4 supplies an interrupt signal to the CPU 42. Thereby, the CPU 42 starts the display information determination process.
When the first pulse signal supplied to the control device 4 is the first pulse signal after the start of time measurement, the second time counter 44 responds to the first pulse signal and the behind leader time Start counting.

As shown in FIG. 4, when the display information determination process is started, the CPU 42 increments the arrival order counter 45 by 1 (step S10). Next, the CPU 42 obtains time information (running time) indicating the time when the first pulse is supplied from the first time counter 43 and rank information from the arrival order counter 45, and associates both to obtain the memory 48. (Step S11).
Thereafter, the CPU 42 acquires the value of the interrupting flag held in the memory 48 (step S12). When the value of the flag is 1 (step S12; Yes), the display information determination process ends. On the other hand, when the value of the flag is 0 (step S12; No), an interrupt display process is executed (step S13).

  As shown in FIG. 5, when the interrupt display process is started, the CPU 42 accesses the memory 48 and sets the interrupting flag to 1 (step S131). Next, the CPU 42 supplies the time information and the rank information acquired in step S11 to the selector 46 as interrupt display information via the output unit 47. Then, the CPU 42 causes the selector 46 to select interrupt display information. As a result, interrupt display information is supplied from the selector 46 to the display panel 5 via the output unit 47. The display board 5 displays the rank information acquired in step S11 on the second display unit 52, and displays the time information acquired in step S11 on the third display unit 53 (step S132). And CPU42 acquires a running time from the 1st time counter 43 regularly (for example, every 0.01 second), and whether the acquired running time passed N seconds from the running time acquired at step S11. Determination is made (step S133). If N seconds have not elapsed (step S133; No), the running time is acquired again, and the determination in step S133 is performed. On the other hand, if N seconds have elapsed (step S133; Yes), the interrupting flag is set to 0 (step S134).

  Thus, since the interrupting flag is set to 1 during the execution of the interrupt display process, even if the competitor passes the measurement point and the grip switch 3 is pressed during the interrupt display, the competitor's The running time and the corresponding rank are not displayed on the third display unit 53 and the second display unit 52.

Next, the CPU 42 causes the selector 46 to select normal display information (step S135). Thereby, normal display information is supplied to the display board 5. That is, the second display unit 52 displays the latest rank information, and the third display unit 53 displays the behind leader time.
Thus, the interrupt display process ends.
Returning to FIG. 4, the display information determination process is also terminated.

  According to the above procedure, the second display unit 52 of the display panel 5 has passed the measurement point when the first switch G is pressed for a predetermined N seconds after the first switch G is pressed. The player's ranking is displayed, and the third display portion 53 displays the run time of the athlete who has passed the measurement point when the first switch G is pressed. Then, after N seconds have elapsed since the first switch G was pressed, the second display unit 52 displays the latest ranking (the number of the last players who have already passed the measurement point), and the third display The display unit 53 displays behind leader time.

  In the present embodiment, the display information determination process is described as being implemented by software capable of performing a plurality of the above procedures in parallel. However, the display information determination process is performed as described above. As long as the same result as the procedure is obtained, it may be different from the above procedure.

With reference to FIG. 3, the display content of the display board 5 is demonstrated concretely.
FIG. 3A shows the display board 5 when the second runner passes the measurement point at the time of running time 1: 08.29, the first switch G is pressed, and 4 seconds have passed since then. Indicates the state. The first-ranked player passed the measurement point 3 minutes 54 seconds ago, and the third-ranked player passed the measurement point one second later than the second-ranked player. Competitors have not yet passed the measurement point.
At this time, the CPU 42 is in the process of interrupt display, and has the selector 46 select interrupt display information. Therefore, as shown in FIG. 3A, the first display unit 51 of the display panel 5 has a running time of 1: 08.33, and the second display unit 52 has the second place competition. 002, which is the player's ranking, and 1: 08.29, which is the run time of the second-ranked competitor, are displayed on the third display unit 53, respectively.

  When one second has elapsed, the CPU 42 finishes the interrupt display process and causes the selector 46 to select normal display information. For this reason, as shown in FIG. 3B, the first display unit 51 of the display panel 5 has a running time of 1: 08.34, and the second display unit 52 has the latest rank. 003 is displayed on the third display unit 53 as 0:03:59 which is the behind leader time.

  In this way, the control device 4 switches display between interrupt display information consisting of the run time and the order corresponding to the run time, and normal display information consisting of the behind leader time and the order information at that time, by display information determination processing. Therefore, it is possible to display the behind leader time and the running time that are useful for the competitors and the audience without reducing the visibility.

  In the present embodiment, as the additional information displayed on the third display unit 53, the running time and the behind leader time are switched and displayed, and the ranking information displayed on the second display unit 52 corresponds to the running time. Although the ranking information and the latest ranking information are switched and displayed, the behind display time is always displayed on the third display portion 53, and the latest ranking information is always displayed on the second display portion 52. Also good.

  In the present embodiment, the case where the run time of the athlete who has passed the measurement point within the period of N seconds is not displayed after the run time is displayed is described as an example. However, while the run time of a certain athlete is displayed, When the athlete passes the measurement point, the display of the running time of the certain athlete may be stopped and the running time of the other athlete may be displayed.

  In this embodiment, the case where a manual switch is employed as the switch has been described as an example. However, the present invention can also be applied to a time measurement system and a display control system using other switches (for example, a photoelectric switch). .

  In this embodiment, the case where the control device is configured by a CPU, a memory, a storage device, and the like has been described as an example. However, the present invention relates to a time measurement system and a display having a control device configured without using a CPU or the like. It can also be applied to control systems.

  In the present embodiment, the output unit of the control device has been described by taking as an example a configuration in which information to be displayed on each display unit of the display panel is converted into a format that can be received by each display unit, and output. Can be applied to a time measurement system, a display control system, and a display panel, which are control devices having a display control means for converting information to be displayed on each display unit into a format that can be received by each display unit.
