Abstract

The device has an impact wall consisting of several measurement frames with tensioned sheets, a fixed holding frame and suitable sensors that detect the forces between the measurement and holding frames when a ball impacts a sheet. The exact position of the ball on the sheet is derived from just the determined force distribution. The speed of striking the ball is derived from the sum of the individual forces.

Description

Die Erfindung ist ein Simulator zum Trainieren und Spielen von Golf. Der Golfsimulator kann in geschlossenen Räumen und insbesondere im Freien als Spiel- und Trainingsgerät verwendet werden. Dabei wird von einem definierten Abschlagpunkt (Abb.1(3)) ein Golfball mit den handelsüblichen Schlägern gegen die Prallwand (Abb.1(1)) geschlagen.
Der Zweck des Simulators ist es, die Größen der Flugbahn eines geschlagenen Golfballes zu bestimmen. Zu diesen Größen zählen unter anderem die Weite des Schlages und die Koordinaten des Landepunktes. Durch die Begrenzung der Flugbahn durch die Prallwand (Abb.1(1)) kann auf eingeschränkten Platzverhältnissen das Golfspiel simuliert werden.
Bei bekannten Geräten dieser Art kommen in der Regel sehr aufwendige und teuere Sensoren oder Bildverarbeitungssysteme zum Einsatz. Diese Meßsysteme sind zudem empfindlich gegen Witterungseinflüsse wie Niederschlag, Verschmutzung und Belichtungsänderungen. Dies bedingt den Einsatz in geschlossenen Räumen oder erfordert bestimmte Schutzvorrichtungen für die Sensorik. Systeme (z.B. US Patent 5,221,082), die sich auf das Prinzip der Messung und Auswertung der Kräfteverteilung stützen, benötigen zur Ermittlung der Abschlagsgeschwindigkeit ein weiteres Sensorsystem, mit dem die Dauer der Flugzeit zwischen Abschlagpunkt und Netz bestimmt wird. Diese Erfindungen sind bedingt durch ihren Aufbau mit einem verhältnismäßig hohen Aufwand zu montieren bzw. demontieren.The invention is a simulator for training and playing golf. The golf simulator can be used in closed rooms and especially outdoors as a game and training device. A golf ball is hit from a defined tee point (Fig.1 (3)) with the usual clubs against the baffle (Fig.1 (1)).
The purpose of the simulator is to determine the sizes of the trajectory of a hit golf ball. These variables include the range of the stroke and the coordinates of the landing point. By limiting the trajectory through the baffle (Fig.1 (1)), golf can be simulated in restricted spaces.
Known devices of this type generally use very complex and expensive sensors or image processing systems. These measuring systems are also sensitive to weather influences such as precipitation, pollution and changes in exposure. This requires use in closed rooms or requires certain protective devices for the sensors. Systems (eg US Pat. No. 5,221,082) which are based on the principle of measuring and evaluating the distribution of forces require an additional sensor system for determining the tee speed, with which the duration of the flight time between the tee point and the network is determined. Due to their structure, these inventions can be assembled and disassembled with a relatively high outlay.

Aufbau des Golfsimulator im Ausführungsbeispiel Abb. 1:Structure of the golf simulator in the exemplary embodiment Fig. 1:

Der Golfsimulator besteht im Wesentlichen aus einer Prallwand (Abb.1(1)) und einem elektronischen Auswertegerät (Abb.1(2)). Die in der Prallwand (Abb.1(1)) eingebauten Sensoren (Abb.2(9)..(12)) sind mit dem Auswertegerät (Abb.1(2)) verbunden. Es werden keine weiteren Sensoren benötigt. Die Prallwand (Abb.1(1)) dient in erster Linie dazu Meßwerte zuerfassen, um die Flugbahn des Balles zu errechnen. Weiterhin muß die Prallwand (Abb.1(1)) die geschlagenen Bälle auffangen.
Die Prallwand (Abb.1(1)) besteht aus den Komponenten Meßrahmen mit Plane (Abb.2(5)+(6)), Halterahmen (Abb.2(4)), Federelementen mit Sensoren (Abb.2(9)..(12)) und der Aufhängung (Abb.2(7)+(8)) des Meßrahmens (Abb.2(5)) an den Halterahmen (Abb.2(4)).
Der rechteckige Meßrahmen (Abb.2(5)) ist an seinen Eckpunkten über Federelemente mit einem starren Halterahmen (Abb.2(4)) verbunden. Durch diese Verbindung wirken zwischen Meß- und Halterahmen (Abb.2(4)) Kräfte, sobald ein Golfball die Plane (Abb.2(6)) der Meßwand in Bewegung setzt. Die Größe der jeweiligen Kräfte an den vier Eckpunkten wird mit geeigneten Sensoren (Abb.2(9)..(12)) gemessen. The golf simulator essentially consists of a baffle (Fig.1 (1)) and an electronic evaluation device (Fig.1 (2)). The sensors (Fig.2 (9) .. (12)) installed in the baffle (Fig.1 (1)) are connected to the evaluation device (Fig.1 (2)). No further sensors are required. The baffle (Fig.1 (1)) is primarily used to record measured values in order to calculate the trajectory of the ball. The baffle (Fig. 1 (1)) must also catch the balls hit.
The baffle (Fig.1 (1)) consists of the components measuring frame with tarpaulin (Fig.2 (5) + (6)), holding frame (Fig.2 (4)), spring elements with sensors (Fig.2 (9) .. (12)) and the suspension (Fig.2 (7) + (8)) of the measuring frame (Fig.2 (5)) on the holding frame (Fig.2 (4)).
The rectangular measuring frame (Fig.2 (5)) is connected at its corner points to a rigid holding frame (Fig.2 (4)) via spring elements. Through this connection, forces act between the measuring and holding frame (Fig.2 (4)) as soon as a golf ball sets the tarpaulin (Fig.2 (6)) of the measuring wall in motion. The size of the respective forces at the four corner points is measured with suitable sensors (Fig.2 (9) .. (12)).

Das Auswertegerät (Abb.1(2)) erfaßt die Sensordaten und führt alle erforderlichen Berechnungen aus. Außerdem werden darauf die Meßdaten dargestellt. Das Auswertegerät (Abb.1(2)) besitzt die Eigenschafen die elektrischen Signale der Sensoren (Abb.2(9)..(12)) in digitale Informationen zu wandeln und diese weiter zu verarbeiten. So wird von dem Gerät selbständig erkannt, ob sich die Prallwand (Abb.1(1)) in Ruhe befindet, ob Luftströmungen auf die Wand wirken oder ob ein Ball dagegen geschlagen wurde. Ein geschlagener Ball löst im Gerät automatisch den Berechnungsalgorithmus aus, welcher alle für den Spieler interessanten Daten berechnet. Über ein Display werden diese Daten angezeigt. Eingabefunktionen ermöglichen es, die Spiel- und Trainingsprogramme zu steuern. Eine Spielvariante wäre z.B., daß zwei Spieler abwechselnd Bälle gegen die Wand spielen und die Entfernung des Balles ermittelt wird. Die jeweiligen Entfernungen werden dann für jeden Spieler aufaddiert. Gewonnen hat der Spieler, der nach einer vorgegebenen Anzahl von Schlägen die weiteste Gesamtentfernung hat. Als Trainingsvariante kann z.B. die Wiederholgenauigkeit einzelner hintereinander ausgeführter Golfschläge ermittelt werden.
Werden im Auswertegerät (Abb.1(2)) die Eigenschaften der Oberfläche gespeichert, auf der der Ball landen würde, so kann auch das Springen und das Ausrollen des Balles berechnet werden.
Ferner können mit der Anzeige von Meßgrößen wie Abschlagwinkel und Abschlaggeschwindigkeit Daten über den Golfschlag zur Verfügung gestellt werden, die beim realen Golfspiel nicht vorliegen. Dadurch sind weitergehende Analysen des ausgeführten Schlages für den Lehr- und Trainingsbetrieb möglich.The evaluation unit (Fig.1 (2)) records the sensor data and carries out all the necessary calculations. In addition, the measurement data are displayed on it. The evaluation device (Fig.1 (2)) has the properties to convert the electrical signals of the sensors (Fig.2 (9) .. (12)) into digital information and to process it further. The device automatically detects whether the baffle (Fig.1 (1)) is at rest, whether air currents are acting on the wall or whether a ball has been hit against it. A hit ball automatically triggers the calculation algorithm in the device, which calculates all data of interest to the player. This data is shown on a display. Input functions make it possible to control the game and training programs. A game variant would be, for example, that two players alternately play balls against the wall and the distance of the ball is determined. The respective distances are then added up for each player. The winner is the player who has the longest total distance after a predetermined number of strokes. As a training variant, the repetition accuracy of individual golf shots carried out one after the other can be determined.
If the properties of the surface on which the ball would land are saved in the evaluation device (Fig. 1 (2)), the jumping and rolling out of the ball can also be calculated.
Furthermore, with the display of measured variables such as tee angle and tee speed, data about the golf shot can be made available which is not available in the real golf game. This enables further analysis of the impact performed for teaching and training purposes.

Aufbau der Prallwand Abb. 2:Structure of the baffle Fig. 2:

Die Prallwand (Abb.2) besteht aus einem starren Halterahmen (Abb.2(4)) und einem Meßrahmen (Abb.2(5)), in den eine Plane (Abb.2(6)) gespannt ist. Über eine Aufhängung (Abb.2(7)+(8)) sind die beiden Rahmen so verbunden, daß der Meßrahmen (Abb.2(5)) sich in gewissen Grenzen mit geringsten Reibungsverlusten parallel zur Schlagrichtung bewegen läßt. Zwischen dem Halterahmen (Abb.2(4)) und dem etwa gleich großen Meßrahmen (Abb.2(5)) sind in den Ecken Federelemente angebracht, über die eine mechanische Verbindung zwischen den Rahmen besteht. An den Eckpunkten zwischen den beiden rechteckigen Rahmen befinden sich zudem Sensoren (Abb.2(9)..(12)), um die zwischen den Rahmen wirkenden Kräfte zu messen.
Die so konstruierte Prallwand (Abb.1(1)) besitzt die Eigenschaften sehr robust, kompakt und unempfindlich gegen äußere Einflüsse zu sein. Die Funktion aller Komponenten wird durch Feuchtigkeit, Verschmutzungen, Temperaturschwankungen und Belichtungsänderungen im Rahmen der Meßgenauigkeit nicht beeinflußt. Der kompakt gehaltene Aufbau der Prallwand (Abb.1(1)) ermöglicht einen einfachen und schnellen Auf- und Abbau. Durch den einfachen Aufbau der Mechanik und Sensorik ist der Golfsimulator sehr kostengünstig herzustellen Diese Eigenschaften ermöglichen den Betrieb der Erfindung in geschlossenen Räumen und insbesondere im Freien.The baffle (Fig.2) consists of a rigid holding frame (Fig.2 (4)) and a measuring frame (Fig.2 (5)), in which a tarpaulin (Fig.2 (6)) is stretched. The two frames are connected via a suspension (Fig.2 (7) + (8)) in such a way that the measuring frame (Fig.2 (5)) can be moved within certain limits with minimal friction loss parallel to the direction of impact. Between the holding frame (Fig.2 (4)) and the measuring frame of approximately the same size (Fig.2 (5)), spring elements are attached in the corners, via which there is a mechanical connection between the frames. At the corner points between the two rectangular frames there are also sensors (Fig.2 (9) .. (12)) to measure the forces acting between the frames.
The baffle constructed in this way (Fig.1 (1)) has the properties of being very robust, compact and insensitive to external influences. The function of all components is not affected by moisture, dirt, temperature fluctuations and changes in exposure within the scope of the measuring accuracy. The compact design of the baffle (Fig.1 (1)) enables quick and easy assembly and disassembly. Due to the simple structure of the mechanics and sensors, the golf simulator can be produced very inexpensively. These properties enable the invention to be operated in closed rooms and in particular outdoors.

Meßverfahren des Golf Simulators:Measuring procedure of the golf simulator:

Um die Weite des Schlages und die Landekoordinaten zu berechnen sind im Wesentlichen die Abschlagsgeschwindigkeit (v0) sowie die Position des Balles auf der Prallwand (Abb.1(1)) zu ermitteln.
Diese beiden Parameter werden im Ausführungsbeispiel mit vier an den Eckpunkten verteilten Sensoren (Abb.2(9)..(12)) ermittelt, die eine der jeweiligen Kraft proportionalen Spannung an das Auswertesystem abgeben. Über die Kraftverteilung kann dann die Position des auftreffenden Balles ermittelt werden.
Die Geschwindigkeit wird mit Hilfe des gesamten Kraftimpulses auf alle Sensoren (Abb.2(9)..(12)) errechnet.In order to calculate the width of the stroke and the landing coordinates, essentially the tee speed (v 0 ) and the position of the ball on the baffle (Fig. 1 (1)) must be determined.
In the exemplary embodiment, these two parameters are determined with four sensors (Fig. 2 (9) .. (12)) distributed at the corner points, which transmit a voltage proportional to the respective force to the evaluation system. The position of the impacting ball can then be determined via the force distribution.
The speed is calculated with the help of the total force impulse on all sensors (Fig.2 (9) .. (12)).

Aus den Größen der Kräfte in den Eckpunkten läßt sich nach den Gleichungen 1 und 2 die Position bestimmen, an der ein geschlagener Ball die Prallwand (Abb.1(1)) trifft.

Dadurch, daß die Position des Abschlagpunktes (Abb.1(3)) bekannt ist und die Position des Auftreffpunktes über die Kräfteverhältnisse bestimmt wurde, kann der horizontale Abschlagwinkel α nach Gleichung 3 berechnet werden

Damit die Flugweite berechnet werden kann ist es erforderlich die Abschlagsgeschwindigkeit v0 zu bestimmen.
Die in die Prallwand (Abb.1(1)) eingeleitete Energie und somit die Summe der gemessenen Kräfte ist ein Maß für die Abschlaggeschwindigkeit. Über die Summe der Kräfte und einen experimentell ermittelten Kalibrierfaktor wird die Abschlaggeschwindigkeit nach Gleichung 4 berechnet.

[N] So that the flight distance can be calculated, it is necessary to determine the tee speed v 0 .
The energy introduced into the baffle (Fig.1 (1)) and thus the sum of the measured forces is a measure of the tee speed. The tee speed is calculated according to equation 4 using the sum of the forces and an experimentally determined calibration factor.
