Abstract
The invention relates to a device for assisting a judge to judge whether a ball is dropped on the outer side boundary or not in a tennis match or a badminton match. The device is mainly composed of three parts of a laser transmitter group, a laser sensor and a circuit. The three parts are electrically connected. The laser transmitter group transmits parallel laser beams and allows the laser beams to be transmitted by attaching with the outer side boundary of a court, and the laser beams are received by the laser sensor. When the ball touches the side boundary, the laser beams are blocked, the circuit is conducted by the laser sensor, and the circuit controls a light-emitting diode to emit the light, thereby providing the assisted basis to the judge for judging whether the ball is fallen on the outer side boundary. As an assisted tool for the judge, the device can improve the accuracy of the judgment of the judge and effectively reduce the erroneous judgment of the judge. The device has the advantages of reasonable structure, convenient use and rapid reaction, thereby being applicable to the high-level playing fields.
Description
Technical field
The present invention relates to a kind ofly can the assistant judge in tennis, badminton game judge whether ball pounds the device at outer edge.
Background technology
Along with the develop rapidly of world sport campaign, the judge of emulation drive is also had higher requirement.Current, in tennis, badminton game, mainly be whether to pound line, but, cause this judgement subjectivity too strong because sometimes the speed of ball is too fast and placement is too special with linesman's visual determination ball, be easy to generate misjudgement.For example: in the tennis tournament, the speed of ball is very fast, causes judge misjudgement the easiliest when outer edge.Therefore, improve the scientific and technological content of judge's ruling instrument, guarantee that the accuracy of judging has become the problem that presses for solution now.
Summary of the invention
The object of the invention is to provide a kind of assistant judge to judge whether ball in tennis, the badminton game pounds the device at outer edge, comprises that laser transmitter group, laser inductor, circuit three parts form.
The object of the present invention is achieved like this.
This device is placed laser transmitter group and laser inductor in the both ends horizontal of tennis, badminton game place outer edge.Apparatus of the present invention in use, laser transmitter group emission multi beam parallel laser (distance of parallel laser interfascicular decide according to the ball area that contacts to earth) allows collimated laser beam paste outer edge surface, court and transmits, and received by laser inductor.The control laser transmitter group, the overall width that allows its emitted laser bundle constitute equals the width in sideline, court.When laser beam was not subjected to stopping, circuit was in off-state.Just run into the laser beam on surface, sideline when ball is fallen on the sideline, court, this moment, light path was stopped, formed path by laser inductor by circuit, and by circuit control lumination of light emitting diode.When stopping that object leaves laser optical path, laser inductor allows circuit formation open circuit again, and diode extinguishes, and is that task is prepared down simultaneously.The present invention provides a kind of to touch judge and has judged whether ball pounds the foundation that drops on the sideline.Though players also might touch the sideline, players and ball touch simultaneously that the probability in sideline is few, and this device still can play certain booster action, and last decision-making is by judge's decision.That the present invention has is rational in infrastructure, it is simple to install, reaction is quick, high accuracy for examination, is suitable for high-caliber tennis, badminton game place.
Description of drawings
Fig. 1 is the structural representation in a sideline in the competition area;
Fig. 2 is the structure chart of laser transmitter group and laser inductor;
Fig. 3 is a structural representation of the present invention;
Fig. 4 is circuit theory diagrams of the present invention;
The invention will be further described with enforcement below in conjunction with accompanying drawing.
Embodiment, in conjunction with Fig. 1, among Fig. 11 be competition area an outer edge, 2 for laser transmitter group, 3 for laser inductor.
Embodiment, in conjunction with Fig. 2,1 is that Laser emission end, 2 is that light pipe, 3 is that the interior 45 degree level crossings, 4 of light pipe are that laser induced end, 5 is that height-adjustable rotation circle, 6 is that base, 7 is an objective table among Fig. 2.
Embodiment, in conjunction with Fig. 3,1 is that laser transmitter group, 2 is laser inductor among Fig. 3.
The specific embodiment
Embodiment: structure is made up of laser transmitter group, laser inductor, circuit three parts as shown in figures 1 and 3.Wherein electric routing battery, light emitting diode are formed, and carry out being electrically connected between them.With laser transmitter group and laser inductor horizontal setting two ends on tennis, badminton game place outer edge respectively, during arrangement certain distance can be arranged from the two ends of outer edge, can avoid players' device of by mistake stepping on during the games like this.Laser inductor is connected with circuit by lead; Regulate highly rotation circle 5, make laser transmitter group emitted laser bundle behind light pipe 2, paste the transmission of surface, sideline, court, receive by laser inductor at last; Allow the distance of parallel laser interfascicular be 0.5 centimetre, guarantee like this as long as ball is bound to touch laser beam when falling on the sideline; When ball touched the sideline, laser beam was stopped that by circuit turn-on, light emitting diode is bright by laser inductor, and the auxiliary foundation of judgement is provided to the judge.When ball left the sideline, laser inductor received laser again, and circuit disconnects, and diode extinguishes, and was that task is prepared down simultaneously.
Claims (4)
1, a kind ofly judges that ball goes out the servicing unit of outside line in tennis, the badminton game, comprise that laser transmitter group, laser inductor, circuit three parts form.
2, according to claim 1ly a kind ofly judge whether tennis, shuttlecock drop on the device of outer edge, and it is characterized in that: described laser transmitter group can be launched the multi beam parallel laser.
