2. Description of the Related Art A conventional flying warning device detects the speed of each boat before a start line, predicts a boat that may fly, based on the detected speed, and issues a warning to a player of the boat. A reset laser emitting unit that emits a reset laser to each boat, and a plurality of pulses that are installed at a predetermined interval in front of the start line and emit a pulse laser on the competition surface to form a flying warning determination line. A laser emitting unit, a control unit and a receiving unit for controlling the operation of the reset laser emitting unit and the pulse laser emitting unit, and a speed of the boat is calculated based on the plurality of pulse lasers received by the receiving unit; It includes a warning unit that predicts the presence or absence of flying when the boat advances at this speed, and issues a warning to the athlete when predicting that there is flying. (See, for example, Japanese Patent Application Laid-Open No. 7-642)
FIG. 2 is a schematic diagram showing an example of the related art. The alarm unit 6 is installed on each boat 10 and includes a receiving unit, a calculating unit, a determining unit, a display unit, and a clock (not shown).

The large timepiece 1 is installed on a start line 50 and has a predetermined time until start,
That is, the time when the boat 10 must start from the pit 20 and reach the start line 50 (for example, 2 minutes)
Time. The large clock 1 activates the reset laser emitting unit 3 via the control unit 2 when starting timekeeping, counts down the aforementioned clock, and outputs the remaining time until the start to the aforementioned determination unit.

When the boat 10 passes through the flying warning determination line 5, the above-mentioned receiving unit operates as a pulse laser emitting unit 4a,
Receiving the pulse laser emitted by 4b, the above-mentioned arithmetic unit calculates the current speed of the boat 10, and calculates the time T2 required to reach the start line 50 when the boat 10 sails at this current speed.

The above-mentioned determination section obtains the difference between the time T2 and the remaining time until the start of counting down the above-mentioned clock, predicts the presence or absence of flying, and displays the result on the above-mentioned display section.

In the flat ink start method, for example, within a certain time (0 to
1 second), the start line 50 and the line 60 before it
If all the boats 10 are in between, the race is established, and each player adjusts the speed of his / her own boat based on the information displayed on the above-mentioned display unit and tries to establish the race.

[0007]

The above-mentioned conventional flying warning device does not take into account the effects of the wind direction and the wind speed on the water surface from the flying warning determination line to the start line on the speed of the boat. If there is a strong wind, there is a drawback that the flying prediction accuracy is incorrect.

[0008]

According to a first aspect of the present invention, a wind speed and wind direction sensing type flying warning device detects the speed of each boat in front of a start line, and predicts a boat which is likely to fly from this speed. A warning is issued to the athlete of the boat, and a reset laser emitting section that emits a reset laser to each boat is installed at a predetermined interval before the start line, and a pulse laser is fired on the competition water surface A plurality of pulsed laser emitting units to form a flying alarm determination line, a control unit and a receiving unit for controlling the operation of the reset laser emitting unit and the pulsed laser emitting unit, and a plurality of pulses received by the receiving unit. Based on the laser, calculate the speed of the boat, predict the presence or absence of flying when the boat advances at this speed, and alert the competitor if it is predicted that there is flying. That the flying alarm device and an alarm unit, the wind speed to the prediction condition, wind velocity, characterized in that, including information on wind direction, wind direction-sensitive flying alarm device.

According to a second aspect of the present invention, there is provided a wind speed and wind direction sensing type flying warning device on land (or on water) near a start line.
A wind speed and wind direction sensor installed in a wind sensor, a wind information laser emitting unit for emitting wind information obtained from the wind speed and wind direction sensor from land (or water) to a boat, and an optical signal from the wind information laser emitting unit , A second light receiving unit for receiving an optical signal from the reset laser emitting unit, and a third light receiving for receiving an optical signal from the first and second pulsed laser emitting units. Unit, a clock that starts a countdown based on the output signal of the second light receiving unit and outputs a time signal, and a speed of the boat based on the time signal and the output signals of the first and third light receiving units.

FIG. 1 is a block diagram showing one embodiment of the present invention. The wind speed and wind direction sensing type flying warning device shown in FIG. 1 includes a wind speed and wind direction sensor 101 installed on land (or on water) near a start line, and a wind speed and wind direction sensor 1.
01 from the land (or from the water) toward the boat, and a light receiving unit 61c receiving an optical signal from the wind information laser emitting unit 102
A light receiving unit 61b for receiving an optical signal from the reset laser emitting unit 3, a light receiving unit 61a for receiving an optical signal from the pulsed laser emitting units 4a and 4b, and counting down based on an output signal of the light receiving unit 61a.

Since the wind information laser emitting unit 102 must be installed in a place where the boat 10 can be seen, the wind information laser emitting unit 102 is located in the boat racetrack and is naturally exposed to the eyes of the spectators. It is also difficult to bring the interfering laser beam irradiator into the boat racecourse and falsify the wind speed and direction to influence the game result. If it is desired to use a wind information radio wave emitting unit instead of the wind information laser emitting unit 102, it is necessary to take measures to encrypt the transmission information and to ignore the interfering radio waves radiated from outside the racetrack.

[0013]

The wind speed and wind direction sensing type flying warning device of the present invention incorporates the wind direction and the wind speed as parameters for predicting the flying, so that an accurate warning can be issued.
