Abstract

The device has sensors (5) arranged in opposite goal posts (1), and an evaluating unit (7) for assigning co-ordinates of an entry position and entry speed of a special object to preprogrammed values. The co-ordinates and/or the values are separated and transmitted to a display unit (8) and are optically and acoustically realized in the display device. The sensors radiate and receive infrared radiations with different frequencies, where the distance of the sensors from the goal post and a goal latch (2) is smaller than diameter of the object entering into a radiation grid.

Description

The invention relates to a device for detecting, evaluating and displaying data for determining the entry location and the time of entry of an object into a radiation grid formed by sensors.

The device can be used in particular as a training or game device for various sports in which a ball, puck or other game object is moved to a goal. With the device can be specifically train the accuracy and firing hardness and complex game situations, such as the eleven-meter shooting in football with and without goalkeeper simulate.

Simple devices for training the shooting accuracy, such as the Torwand used for decades in the current sports studio of the Second German Television goal wall with circular bullet holes bottom right and top left are known. With such a goal wall a comprehensive training is not possible because the hit positions are statically predetermined and the hits are achieved independently of the shooting speed and changing game situations.

In another training or game device of the type mentioned ( DE-OS 2854165 ) is provided in the goal area a baffle on which a ball touches an electronically sensitized hit field and thus one of the respective impact position attributable valence determination can be displayed. A disadvantage of this embodiment is not only the high design complexity, but also that only firmly kicked goal shots are recorded and thus the exact scoring is not always possible.

From the DE 195 08 742 A1 is a portable electronic football goal with built-in light barrier grid for measuring and evaluation of the placement of a ball shot with a standing inside the outer goal frame without contact with the goal frame photoelectric frame known. Although this device allows a largely accurate position determination of the entry of the ball in the beam grid. However, a measurement of the entry speed and a simulation of game situations is not possible with this device.

A similar training and game machine for ball games is from the DE 20304144 U1 in which the entry position of the game ball is also detected by a beam grid formed with optical sensors and the data is connected to an evaluation electronics and a display unit representing a game result. Even with this training and game device, an exact determination of the firing speed is just as impossible as the use of complex game systems. In addition, the light barrier grid is so coarse-meshed that it is not ensured that with each shot also a vertical and a horizontal light beam is interrupted at the same time. Also US 2006/178236 discloses a coarse-meshed light barrier grid according to the preamble of claim 1.

The invention is therefore based on the object, a device of the type mentioned in such a way that both the exact entry position of the game object in the goal frame, as well as its entry speed can be detected and evaluated together with the entry position. In addition, it should be possible in an improved embodiment of the device to simulate complex game situations, such as the eleven-meter shooting in football with goalkeeper as realistic as possible.

The invention solves this problem with a device having the features of claim 1. Further embodiments can be found in claims 2 to 15. The device according to the invention comprises a goal frame, which consists of at least two lateral goal posts and a door slat arranged thereon. The measuring device consists of sensors arranged in the area of the opposite goalposts according to the transmitter-receiver principle and sensors located in the region of the crossbar, which interact with a reflection element located at the bottom between the goalpost and the door slat, and a signal transmitter arranged at a distance from the goal frame. from whose position the game object is moved onto the goal frame. The sensors and the signal generator are connected to a computer, which consists of the time between the departure of the game object from the location of the signal generator and the time of entry of the game object in the beam grid and from the place of entry of the game object in the beam grid and the distance between the Signal generator and the determined entry the speed of the game object when entering the beam grid calculated.

The computer forwards the determined coordinates of the entry location and the entry speed to an evaluation unit which assigns preprogrammed values to these data. The coordinates farthest from the center of the gate are assigned the highest values for the in-game system. The values decrease towards the middle. Similarly, higher firing speeds are assigned higher values than lower firing speeds. This preprogrammed value system of the evaluation device should allow the most realistic possible simulation of a goal shot, as a ball or other game object with higher speed and positioning at a location that is as far away from the middle position of the goalkeeper, has higher scoring chances, as a slow moving game object, that can be easily reached by the goalkeeper without much movement.

The evaluation unit forwards the coordinates of the entry location, the speed of the object upon entry into the beam grid and / or the values determined from these data by the evaluation unit to a display unit on which they are made visually and / or acoustically perceptible.

In order to be able to use the device also for more complex game systems, the beam grating must be able to be adapted to the size of the game object to be moved and have a precision which ensures in each case that the game object interrupts at least one horizontal and one vertical beam when entering the goal frame and thus at least one vertical and one horizontal coordinate from the computer can be detected. In order to make this possible, the sensors must in any case be arranged and activated at a distance from the goalpost and the slat, which is smaller than the diameter of the play object. Furthermore, at least the sensors arranged directly next to each other should emit and receive deviating frequencies. In more specific embodiments, a variety of different sensors may be used.

If only sensors are used - as known in the prior art exclusively - to emit and receive beams of the same frequency, a close arrangement of the sensors is not possible when the location of the game object in the beam grid is accurately determined. The light beam emitted by the sensor propagates in the manner of a light cone from the transmission sensor to the receiver sensor, so that with a correspondingly narrow arrangement of the sensors, a receiver sensor receives the beams of the adjacent or even more transmission sensors and is no longer able to provide accurate feedback to the computer which ray of light was pierced exactly by the game object. The same problem arises even more in the case of the sensors in the door slat whose light beam is thrown back over the reflection element (3), possibly scattered further.

For the above reason, previously either the sensors had to be arranged in such a large distance from each other that the light beam of a transmission sensor despite its widening met only one receiver sensor, or correspondingly large measurement inaccuracies are accepted. In the case of a large-meshed beam grid, it is not ensured that the game object interrupts at least one vertical and one horizontal beam. Rather, it is possible that depending on the entry of the game object only a vertical or a horizontal beam is interrupted or even the game object without interrupting the Beams through the beam grid passes. For more complex game systems such devices are not suitable with large measurement inaccuracies.

The present invention enables a much tighter arrangement of sensors with a correspondingly accurate determination of the entry location of the game object. The arrangement of different frequencies ensures that the receiver sensor can not receive the light cone of the adjacent beam, since this has a deviating from the predetermined receiver frequency transmission frequency. The receiver sensor can thus receive only the light beam of its associated transmission sensor. In order to increase the accuracy of the device, a plurality of different transmitter / receiver sensor pairs can also be provided.

In an advantageous embodiment, the sensors transmit and receive infrared rays.

The sensors preferably form a beam grid that can define at least 352 hit fields.

In order to be able to vary the number of hit fields and to adapt the diameter of the game object, in a further embodiment all sensors are connected separately to the computer. Each sensor can be controlled and activated separately from the computer.

In order to make the device easily transportable and reassemblable, it is provided in a further embodiment that the goal frame can be dismantled into at least three components: Preferably, these are two goal posts and a door batten, which can be connected to one another either with fastening means or by plug connections ,

It is particularly advantageous in this case if the sensors of each component can be connected to the computer and the power supply with its own cable bundle. In this way, each individual component is independent of the others Components, so that it is not necessary during disassembly and assembly to connect the sensors and the wiring of individual components together. The operability of the device is thus improved and possible sources of error excluded.

In order to protect the arranged on the ground between the goalposts reflection element from dirt and puncture damage, the cover of the reflective elements is provided with a protective strip in a further embodiment. Preferably, this protective strip has recesses on the points opposite the sensors of the door slat, in which a reflection element is arranged or visible. In this way it can be prevented that the protective strip is scratched or damaged over the reflection element and the contact between the arranged in the door slat sensors and the opposite points of the reflection element is disturbed.

In a further preferred embodiment, the individual sensors and the signal generator are connected to the computer in such a way that the computer checks, depending on the density of the set radiation network, whether all the sensors and the signal generator are ready for operation. After checking the operational readiness of the sensors and the signal transmitter, the computer transmits a signal to another display unit which makes recognizable by an optical and / or acoustic signal that the device is ready for operation. Preferably, this display unit is in spatial proximity to the goal frame, i. H. either behind the beam grid or laterally offset next to the goal posts, outside the beam grid.

In a further embodiment, a camera can be arranged in spatial proximity to the goal frame, which receives a picture or an image sequence from the space surrounding the signal generator upon receipt of a signal when leaving the game object from the signal generator. In this way, the user can document his posture when moving the game object and adjust and correct his shooting technique or his movement according to the image or the image sequence of the displayed value.

In another embodiment, the image data is transmitted from the camera to a printer where it can be printed and documented for the user.

This printer can alternatively or cumulatively be used to print out the data determined by the computer and the values defined by the evaluation unit, with or without this image file.

In a particularly advantageous embodiment of the invention, a projection surface is arranged behind the radiation network and the goal frame construction. The projection surface can be either a wall, screen, screen or a net-like structure.

By means of an image generator, such as a film projector, laser or projector, an image, for example the image of a goalkeeper, can be generated on the projection surface. The control signal generated by the signal generator when leaving the game object can be transmitted to the image generator and / or the evaluation unit. After receiving the control signal, the image generator reproduces a preprogrammed image sequence which, for example, corresponds to the reaction of a goalkeeper to a penalty shot.

In a further embodiment, it is provided that for each preprogrammed image sequence on the evaluation an associated evaluation program is stored, that the coordinates, which is covered by the image sequence at the time of entry of the game object in the beam grid, one of the usual, deposited to this coordinate Assign values to different values. Preferably, these coordinates are assigned the value 0 and reproduced on the display unit an optical and / or acoustic signal that the goalkeeper has kept the game object.

To vary the level of difficulty, it is possible to provide image sequences with different gate covers and image speeds.
