Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for measuring a lap time of each moving body when a plurality of moving bodies are traveling on the same course.

More specifically, the present invention relates to a lap time measuring system suitable for measuring the lap time of a race car, for example.

[0003]

2. Description of the Related Art Conventionally, in order to measure a lap time of a race car, a lap time of a plurality of race cars has been measured using a stopwatch or a portable personal computer.

[0004]

However, the above-mentioned conventional example has the following problems.

A) It is not known which race car is currently running on the course.

B) Since it is impossible to grasp how many race cars are on the course, the most important clear lap for time attack cannot be found.

C) It is impossible to know whether the marked race car of the other team is currently running or is in the pit.

D) It is difficult to grasp a race car that has never been on the course.

Therefore, in view of the above points, an object of the present invention is to provide a plurality of traveling vehicles or traveling objects (moving bodies) on the same course.
It is to provide a lap time measuring system configured to display a traveling state of each mobile body in a list form when there is a.

[0010]

In order to achieve the above object, the present invention provides a system for measuring lap times of a plurality of moving bodies when a plurality of moving bodies are traveling on the same course. A visible display means provided on or around the moving body designation key, and a control means for turning on or off the visible display means depending on whether the moving body is traveling on the course or not. It is equipped with.

Here, when the measured lap time is longer than a predetermined set time, it is preferable to turn off the visible display means by judging that the moving body has made a pit stop. Alternatively, it is also possible to turn on the visible display means for a vehicle that has run even once by a certain key input, turn off the visible display means for an unrunning vehicle, and return to the original visible display state after a certain period of time. .

[0012]

According to the present invention, a visual display means such as an LED for indicating the traveling state is provided on or around a plurality of keys for designating a moving body so that the traveling state (running / not running state / Pit-in status) can be managed. That is, the basic flow of the lap time measurement is a work of pressing a pass button when each moving body passes a specific point and pressing a moving body designation key in a corresponding manner.

Further, in the present invention, when the moving body designating key is pressed, the LED or the like provided on or around the moving body designating key is turned on to indicate "running". After that, when the key for designating the moving body is not pressed for a certain period of time, this LED or the like is turned off to indicate that it is in the "unrunning state / pit-in state".

First, at the same time as the race car passes, FIG.
The pass button 23 of is pressed, and the car number of the race car that has passed in response to this is entered from the car number designation keyboard 19.
At this time, the light emitting LED 20 indicating the running state of the race car is turned on, indicating that the race car corresponding to the currently turned-on key is "running". However, if the race car does not re-pass after a certain period of time, it is assumed that the car has entered the pit unless the vehicle cannot be driven due to an accident or trouble, and the light emitting LED 20 is turned off.

Reference numeral 24 is a gate array mainly containing various circuits necessary for the system.

When the race car passes and the pass button 23 is pressed, the CPU 9 recognizes it through the gate array 18. This timing is replaced with the time accumulated by the counter inside the CPU 9 based on the oscillator 8 and is temporarily stored in the static memory 11 as the passage time. Then, the vehicle number is designated by the vehicle number designation keyboard 19 and transmitted to the CPU 9 through the same route as the passage button 23.

First, the CPU 9 turns on the LED corresponding to the vehicle number of the light emitting LED display section in order to inform the operator that "the vehicle is running". Then, the static memory is stored in advance as "passage time" in an area mapped for each vehicle number.

Further, the CPU 9 calculates the lap time from the time when the designated race car passed last time and the time when the race car passed this time, and it is shown to the operator through the lap time display unit 22 at the same time as the vehicle number display unit 21. The CPU 9 provides an interrupt routine of 1 second based on the oscillator 8, in which the elapsed time is calculated for all the race cars currently running with respect to the current time, and if this exceeds a certain time, the race car is already It is determined that the vehicle is not traveling on the course, and the light emitting LED 20 is turned off.

For the measurement, the operator first pushes the pass button 23 at the same time when the race car passes, the CPU 9 accepts the input of the pass button 23 in the pass button input processing 26, and then in the pass button pressing time storage processing 27. The timing at which the pass button 23 is pressed is replaced with the time and temporarily stored in the memory.

Then, the CPU 9 receives the designation of which race car has passed in the vehicle number designation input processing 28 from the operator.

Here, the LED lighting process 2 is one of the features of this embodiment, that is, "the running race car lights up the light emitting LED so that the operator can always recognize it".
9, and the LED on the vehicle number key obtained in the vehicle number designation input process 28 is turned on. Next, in the lap time calculation processing 30, the lap time is calculated based on the time when the race car passed last time and the time when the race car passed this time, and the lap time display 31 notifies the operator of the lap time. Then, the process returns to the pass button input process 26 again.

FIG. 4 is one of the features of this embodiment, "When the race car does not pass again after a certain period of time after passing the race car, the light emitting LED indicating that the vehicle is running is turned off. Is a flow chart showing a processing procedure for realizing "change to the operator."

This process is an interrupt process interrupted at a timing of 1 second obtained by dividing the oscillator 8 inside the CPU 9, and manages the time of the running race car. First, in the current time reading process 33, the time when it is interrupted is read in units of 1 second, and thereafter, the elapsed time of all running race cars is obtained with this value. A variable that points to the race car table (up to 50 cars in this example) is set as a car counter i, and this is set to 1 in the car counter initial setting process 34.

Then, it is checked whether or not the race car pointed by the car counter i is currently running, and if it is not running, the processes 36 to 39 are skipped to the process 40, and if it is running, the elapsed time is elapsed. In the calculation process 36, the time passed last time is subtracted from the time shown in the current time reading process 33 to obtain the elapsed time.

Next, the elapsed time is a certain time (3 in this example).
The elapsed time check processing 37 determines whether or not the number of minutes has been exceeded.
If it exceeds 0, the process goes to the LED extinguishing process 38, and the light emitting LED that is turned on to indicate that the vehicle is running is shifted to the extinguished state that indicates pit-in, and the pit-in flag is set to indicate that pit-in has been made Let's hold it.

The processing for one vehicle is completed as described above, and the pointer is incremented by 1 in the car counter increment processing 40 so that the next race car can be similarly processed.

Finally, the process proceeds to the end judgment process 41 for checking whether or not all the measurable race cars have been subjected to this process. If not, the process returns to the running check process 35 to measure the same process. Repeat until all the units are finished.

As described above, in the present embodiment, not only the lap time measurement but also the race car state is automatically managed for each race car from the passing time and the current time, and the state of each race car, that is, the unrun Condition, running condition,
Light emission L by distinguishing the pit-in state (temporarily stopped state)
