Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a flying recording device used, for example, when starting a small car race.

"Conventional technology" In small car racing (hereinafter referred to as auto racing),
Conventionally, the winner is the person who has been waving the flag manually and has started the race with the signal of the flag, and who has orbited the running path a predetermined number of times within the shortest possible time.

For this reason, it is necessary for the winner to fully open the engine of each car at the time of starting, to shockly start the car with its power, and to make the car run at high speed within the shortest possible time.

Each athlete receives a signal to start by the flag, but if there is a slight difference in the start timing, that time difference will later appear as a large time difference. For this reason, athletes are competing to start a car by predicting a slight sign of whether or not a flag will be waving and to start a car even slightly before other cars.

Because of this situation, flying tends to occur when the auto race starts. However, depending on the number of times you fly and how many seconds before you start, you will be punished such as suspension of participation, so you must make a fair decision on flying.

However, conventionally, a person is placed at the starting position and the presence or absence of flying is monitored by human eyes, but there is a drawback that it is inaccurate because both the flag and the car cannot be seen in the same field of view, It is difficult to make a fair decision because it is unreliable because it depends on human eyes.

Furthermore, in auto racing, the starting position is sequentially shifted backward according to the athlete's performance. In other words, 0 handy line at the beginning 10,20,30 ... 120 1 handy line in all
Three handy lines are provided, and athletes with good results can start from the rear handy line. When there are a plurality of starting positions in this way, the determination of flying becomes more difficult.

For this reason, it is conceivable to install a TV camera at each starting position, monitor the starting condition on a monitor TV, and record it on a recording / playback device so that which player flew later can be reproduced.

"Problems to be solved by devising" With this configuration, since the race is held several tens of times a day, the running situation is recorded for each race and a blank part is provided between the recording blocks. As a result, the recording medium is interspersed with recording blocks for recording the running condition, and it takes time to find a desired recording position for the race later.

However, it takes more time to find the part that recorded the occurrence of flying in each recording block, and it is not practical to manage the competition.

An object of the present invention is to provide a flying recording device that can quickly find the position of a recording block that records the running condition of each race and can find the portion that recorded the occurrence of flying in a short time.

"Means for Solving Problems" In the present invention, the optical switch is installed at the starting position of the racetrack and emits a light beam in a direction crossing the racetrack and an optical switch including a light receiver for receiving the light beam. A flying detector, a TV camera that captures the starting position, a recording / playback device that records the video signal of this TV camera, and when this recording / playback device enters the recording state, the first audio track of this recording / playback device continues. A flying recording device is constituted by continuous signal recording means for recording a signal and flying detection signal recording means for recording a signal indicating the presence of flying on the second audio track of the recording / playback device each time the flying detector detects flying. It was done.

According to the structure of the present invention, the recording / reproducing apparatus enters the recording state from the time when the start command is issued. In this recording state, the continuous signal recording means records the continuous signal on the first audio track.

At the same time, when the flying detector detects the occurrence of flying, the flying detection signal recording means records a signal indicating the presence of flying on the second audio track of the recording / playback apparatus.

As described above, according to the present invention, since the continuous signal is recorded in the first audio track while the image pickup signal from the television camera is being recorded, the continuous signal is reproduced as a sound even in the rewinding or fast-forwarding state. You can quickly find the recording position.

If the recording position is found, the presence or absence of a signal indicating the presence of flying within the recording block can be detected, so that the image position where flying has occurred can be found quickly.

In this way, according to this invention, it is possible to quickly find the recording position of the image in which the flying has occurred, and as a result, it is possible to quickly identify which player has flown, so that a fair flying judgment can always be made. .

Normally, at most eight cars will be competing in one race, and most of them will start from starting position 2A. Therefore, it is enough to have the capacity to display eight start points.

On each screen, at least the numbers representing the starting positions 2A, 2B, 2C ... 2M, race numbers, etc. are displayed. This display is given from the display signal generator to the monitor televisions 18A, 18B, ... 18D so that which screen is at which starting position can be identified.

FIG. 3 shows the overall electrical construction of the device according to the present invention. Reference numeral 21 shown in FIG. 3 indicates a controller. The controller 21 is composed of a microcomputer. As is well known, the microcomputer comprises a central processing unit 21A, a ROM 21B storing a program, a RAM 21C used for temporarily storing data, an input port 21D and an output port 21E.

The input port 21D has an input device 22 such as a key board.
The video controller 17, the flying detector 5, the display signal generator 24, and the time measuring device 25 are connected to each other.

The start signal device 7 and the switcher 26 are connected to the output port 21E.
And the printer 27, etc. are connected.

The switcher 26 is a video controller 17 connected to the input port 21D.
A control signal is given from the output port 21E based on the command input from the TV camera by this control signal.
Video signals sent from 16A to 16M are combined into two screens in an arbitrary combination, and the combined video signals are given to monitor TVs 18A, 18B, ... 18D, and a recording / reproducing device such as a VTR is also provided. It is supplied to 28A and 28B for recording and playback. Further, the switcher 26 is supplied with respective character signals and time measuring signals inputted from the display signal generator 24 and the time measuring device 25, and displays characters indicating the starting position on the monitor televisions 18A, 18B and the recording / reproducing devices 28A, 28B. , Race number, time measurement result, etc. are displayed, and these character signals are recorded together with the image.

When the flying occurs, the printer 27 prints the starting position where the flying occurred and the time at that time (flying occurrence time based on the time when the start command was issued), the finish order, the time of each athlete, etc. Used for printing.

In this invention, recording / reproducing devices 28A, 28B are provided with continuous signal recording means 31A, 31B and flying detection signal storage means 32A, 32B for recording a signal indicating the presence of flying.

The continuous signal recording means 31A, 31B and the flying detection signal storage means 32A, 32B are controlled to be opened / closed by the controller 21, for example, an analog switch or a gate circuit can be used, and an audio frequency signal output from the low frequency oscillator 33. The recording terminal T of each first audio track of the recording / playback device 28A, 28B
The operation of supplying A and the recording terminal TB of the second audio track is performed.

The continuous signal recording means 31A, 31B are controlled to be opened and closed by the controller 21 in cooperation with each other, and the recording / reproducing devices 28A, 28B are switched to the recording state in synchronization with the time measuring device 25 starting the time measurement.

At the same time, the continuous signal recording means 31A, 31B are turned on and a continuous audio signal is given to the recording terminal TA of the first audio track of the recording / reproducing devices 28A, 28B, and the continuous signal 35 is supplied to the first audio track 34 as shown in FIG. To record.

Further, for example, when the start is normally performed, the recording operation of the recording / playback devices 28A and 28B is stopped and controlled by the controller 21 when about 10 seconds have elapsed from the start, and at the same time, the continuous signal recording means 31A and 31B are turned off. To be done. In this way, the continuous signal 35 is recorded in the first audio track 33 for each recording block VD of the image pickup signal.

On the other hand, when the flying detector 5 detects the presence of flying, the flying detection signal recording means 31A and 31B are provided with the shooting signal of the starting position at which the flying has occurred. A signal from the low-frequency oscillator 33 is applied to the recording terminal TB, and as shown in FIG. 4, the track TC ₁ in which the flying image is recorded is recorded.
A signal 36 indicating flying is recorded on the second audio track 34 corresponding to the head positions of TC ₂ and TC ₃ .

The detection of the flying that has occurred during recording and the determination processing are performed as follows. When a start command is given from the input device 22, the time measuring device 25 starts the timekeeping operation from a state before a predetermined time before starting. In this example, it is assumed that the timekeeping operation is started from the state 20 seconds before.

At the same time as the time measuring device 25 starts the clock operation,
21 enters a state of receiving the flying detection signal output from the flying detector 5, and the recording / playback device 28A, 28
B enters the recording state.

The acceptance of the flying detection signal is controlled in the time from when the start command is issued until the start. In other words, it is limited to 20 seconds from issuing the start command to starting. When the flying detection signal is output from the flying detector 5 from 20 seconds before starting to 6 seconds before starting, the controller 21 activates the flying occurrence indicator 11 to turn on all the red lights to prevent the occurrence of flying. indicate. By this display, each athlete knows the occurrence of flying, and each one confirms the position of the wheel and tries to eliminate the flying condition. When the flying state is canceled, the flying generation indicator 11 is turned off and the clocking operation is continued.

The controller 21 activates the pointer 8 5 seconds before starting. 5
When the flying detection signal is given between 2 seconds before and 3 seconds before, the controller 21 stops the hand movement of the pointer 8 and blinks the flying generation display 11 to display the suspension of the competition.

When the flying occurs from 3 seconds before the start to the start, the flying occurrence indicator 11 is blinked to display the occurrence of the flying, and the stop of the start is displayed. At this time, the hand movement of the pointer 8 continues and stops at the starting position, but the reversing plate 9 does not reverse.

On the other hand, if the flying occurs within the time period between 5 seconds before the start and the start, the controller 21 displays a mark indicating that the flying has occurred on the monitor TV 18A or 18B displaying the starting position where the flying has occurred. To do. As this mark, the polarity of the display signal given from the display signal generator 24 is inverted, the black and white of the character displayed on the monitor television is inverted, or the display of the character is blinked in a certain cycle. Etc. are possible.

Therefore, the operator can know that the flying has occurred at the starting positions 2A to 2M displayed on any of the monitor televisions 18A, 18B, ... 18D.

When the controller 21 receives the flying detection signal from 5 seconds before the start to the start, the controller 21 displays the mark indicating the occurrence of the flying as described above, and detects the flying on the second audio track 34 of the recording / playback device 28A, 28B. Record signal 36,
Then, for example, after 2 seconds, the operation is stopped. Controller 21 when stopped
Causes the recording / playback devices 28A and 28B to rewind the tape, and automatically stops at the recording position of the flying detection signal 36.

The operator confirms the occurrence status of flying on the monitor TV 18A or 18B by frame feed at the tape stop position, identifies the flying player, and inputs the vehicle number of the player 22
Enter from. When the vehicle number is input from the input device 22, the vehicle number is displayed on the vehicle number display 13 provided in the start signal device 7.

In this way, the occurrence of flying and the player who has flown can be identified and quickly notified to the stadium.

After the start of the flight is stopped by the flying and the number of the flying car is displayed on the car number indicator 13, the pointer 8 is returned to its original downward position, and the restart indicator 14 is turned on to restart the vehicle. Get ready. The above-described flying determination processing is determination processing when flying occurs during recording.

On the other hand, for example, when it is desired to reproduce the flying situation in a certain number of races when all the races are finished and the recording block VD is recorded over a plurality of times, a recording medium such as a magnetic tape is started or finished. Continuous signal while returning to the position and fast-forwarding or rewinding from that position
By counting the number of playbacks of 35, the position of the recording block of the desired number of races can be found.

By finding the recording block of the desired number of races and searching for the recording position of the flying detection signal 36 in this recording block, the flying situation in that race can be displayed on the monitor television and shown to the player.

“Effect of device” As described above, according to this device, each recording block VD
Since the continuous signal 35 is recorded every time, the continuous signal is reproduced even in the fast forward or rewind state. In other words, a short signal such as the flying detection signal 36 cannot be detected in a fast-forwarding state such as fast-forwarding or rewinding, but by recording the continuous signal 35 as in this invention, the recording block The position can be easily found.

Therefore, according to this invention, even if there are many recording blocks on the recording medium, it is convenient because a desired recording block can be easily found from the recording blocks.

"Modified Example" In the above description, the continuous signal 35 is simply an audible signal. However, for example, a digitally coded signal is given, and a number is assigned to a recording block by the digitally coded signal, and detection is performed in a fast-forward state. It can also be configured so that it is possible to determine which recording block the position is from the beginning.
