Description

[0001] The invention relates to a system comprising a firing device and a sighting device according to the preamble of claim 1. The firing device is designed, for example, in the manner of a pistol. The sighting device is designed, in particular, in the manner of a target. The invention further relates to a firing device and a sighting device of such a system.

[0002] Such a system is explained, for example, in WO 99 / 10700 A1.

[0003] The aiming device has, for example, a type of target. Using the transmitting device of the firing device, shots in the form of shot beams can be fired at the aiming device. The receiving device detects, for example, whether the shot beam has hit the target area or a predefined area of the target area. Depending on the design of the aiming device, the position of the incoming shot beam can be determined more or less precisely. In competitions, there are usually numerous aiming devices. In order to evaluate the shots or shot beams received and scored by the aiming devices during the competition, the aiming devices can be connected to a central computer unit to which the aiming devices transmit scores. In order to assign such scores to respective firing devices orFor example, it is possible to assign a targeting device to a firing device or to an operator of a firing device to the shooter using the respective firing device. However, such an assignment, which could be achieved, for example, through prior registration with the targeting device, is cumbersome in practice.

[0004] It is therefore the object of the present invention to provide an improved system.

[0005] To solve this problem, a system according to the technical teaching of claim 1 is provided.

[0006] To solve the problem, the system also provides a firing device and an aiming device.

[0007] A fundamental concept of the present invention is that, for example, the firing device registers and / or identifies itself with the aiming device using the firing meta-information. However, it is also possible for the firing meta-information to be assigned to a respective firing shot or firing beam, so that, for example, the individual circumstances associated with the respective firing beam or firing shot can be evaluated by the aiming device. For example, the firing meta-information can identify the firing shot or firing beam, for example, using identification information of the firing device, so that the firing shot or firing beam can be assigned to this firing device.

[0008] Each shot meta-information item can be assigned to a single shot beam. However, it is also possible for multiple shot beams to be assigned to a single shot meta-information item, or for multiple shot meta-information items, for example at least two shot meta-information items, to be assigned to a shot beam. It is also possible for the shot meta-information item or items to be assigned only to the firing device, i.e., no shot meta-information items are sent in connection with shot beams. For example, it is possible for the firing device to send only one or more shot meta-information items to the target device, which serve to identify the firing device on the target device.

[0009] The firing device is configured, for example, in the manner of a pistol or rifle, or has a housing that has the shape of a pistol or rifle. Of course, other physical configurations of a firing device are also possible. Preferably, the firing device has a barrel component configured in the manner of a rifle or pistol barrel, with a handle protruding from the barrel component for gripping by an operator. A trigger device is arranged on the handle, with which the operator can trigger the optical firing beam.

[0010] The aiming device is preferably a static and / or statically arranged and / or stationary or stationary arranged and / or intended for stationary arrangement aiming device.

[0011] The aiming device is advantageously not an aiming device that can be arranged on a human operator or is intended to be arranged on a human operator.

[0012] The aiming device forms, so to speak, the target for the firing device. The aiming device can, for example, be designed in the manner of a target or have a target. In particular, the aiming device has a housing which can be arranged on a tripod, for example. However, it is also entirely possible for the aiming device to have, for example, a type of target, as a type of plate on which, for example the rear side, electrical and electronic components, optical components and the like are arranged. However, a design in which the aiming device has a housing is preferred. Electronic or optical components can of course also be present on the front side of the aiming device or target, for example a camera or similar other detection devices for optical detection of, for example, a shot beam.

[0013] Advantageously, the aiming device forms part of an arrangement of several aiming devices which are arranged stationary next to one another and / or in a row.

[0014] The firing device is preferably a portable or mobile firing device that can be freely carried and / or held by an operator to deliver the optical firing beam to the aiming device.

[0015] The shot beam preferably contains a pulse sequence that includes, for example, initialization pulses, etc. The shot metainformation is advantageously information that is separate from the pulse sequence of the shot beam and / or is not contained in the pulse sequence of the shot beam.

[0016] Preferably, the shot beam is a standardized shot beam, meaning that the shot beam is defined by a norm or standard. For example, the length and sequence of the pulses in the pulse train are specified by a norm or standard.

[0017] The standardized or uniform shot beam enables the shooting device designed to transmit the shot meta information to also be used with aiming devices that are not designed to receive shot meta information, but can receive the standardized or uniform shot beam or are designed to receive it.

[0018] A targeting device configured to receive the shot metainformation may also be used with a shooting device that does not transmit shot metainformation but transmits the standardized or uniform shot beam.

[0019] The firing device is configured to transmit the optical firing beam such that the optical firing beam is similar to a firing beam that can be emitted by a second firing device. The firing device according to the invention and the second firing device can form part of a system with at least two firing devices. The second firing device can also be configured according to the invention, i.e., configured to transmit the firing metainformation. However, the second firing device can also be a firing device that is not configured to transmit the firing metainformation.

[0020] It is therefore provided that the firing device and at least one further firing device are each designed and provided for transmitting optical firing beams, which are each of the same type and / or identical and, in particular, indistinguishable from one another. The firing beams have, for example, the same pulse sequences and / or the same temporal and / or physical properties.

[0021] The firing device can form part of an arrangement or a system of at least two firing devices, for example, a first and at least one second firing device, wherein the firing device according to the invention forms the first firing device. The at least one second firing device, i.e., the one further firing device or the several further firing devices, can be configured to transmit the firing metainformation. It is also possible for the at least one second firing device or further firing devices not to be configured to transmit the firing metainformation, i.e., to be configured only to transmit the optical firing beams.It is therefore possible for the firing device to form part of an arrangement or system comprising at least one further firing device, wherein the further firing device may or may not be configured to transmit the firing meta-information.

[0022] The aiming device can be designed to distinguish the shot beams of the first shot device and the at least one second shot device from one another on the basis of the shot meta-information sent by the first and the at least one second shot device and / or to assign them to the first and the at least one second shot device.

[0023] As with the firing device, it is also possible to form a system or an arrangement of aiming devices with the aiming devices. The aiming device according to the invention forms a first aiming device of a system or arrangement that comprises at least one second aiming device. The at least one second aiming device can comprise or be a aiming device that is not designed to receive the firing metainformation or that is designed to receive the firing metainformation. Any combinations of aiming devices that are designed to receive the firing metainformation and those that are not designed to receive the firing metainformation are possible in the system or arrangement.In any case, the aiming devices are designed to receive standardized or uniform shot beams, so that a aiming device designed to receive the shot metainformation and a aiming device not designed to receive the shot metainformation can receive such uniform or standardized shot beams.

[0024] A target area is the area that a shot must hit to be considered a hit. Areas of the aiming device that can also be hit by the shot may extend around the target area. In this case, the shot is a valid shot in itself, meaning it has been fired, but it does not count as a hit.

[0025] Regarding the accuracy with which the aiming device determines the location of the shot beam's impact on the target surface, several possibilities are explained below: The aiming device can be designed to determine whether a shot beam has actually hit the target surface. Such an aiming device is also referred to as a hit target.

[0026] Furthermore, the aiming device can also be a so-called precision target. The aiming device is designed, for example, to assign at least one rating to a received shot beam, which rating depends on the location of the shot beam's impact on the target surface. For example, if the shot beam hits the target surface in the center, it receives a higher rating than if it hits an edge area of the target surface.

[0027] The aiming device can also have at least two different reception zones for the shot beam, each of which is assigned different ratings. For example, a shot beam impinging on a first reception zone can receive a higher rating from the aiming device than a shot beam impinging on a second reception zone. In practice, for example, a aiming device that has 3, 4, or more, for example even 24, different reception zones is advantageous. The reception zones can, for example, extend in a ring around a center. The reception zones are preferably ring-segment reception zones.

[0028] A targeting device designed to have two distinct receiving zones for the shot, each of which has two meanings, "hit" and "miss," is also referred to as a hit-and-miss target. Of course, this can also be achieved with a targeting device that has multiple receiving zones or is designed like a precision target, generating the "hit" and "miss" scores through software or a suitable analysis of shot beams or received shot beams to the respective receiving zones. Typically, the "miss" zone is located in the center of the target area and has a specific diameter. Outside of this defined "hit" zone is the "miss" zone, which can be scored as a failed attempt according to the applicable rules.The problem here, however, is that shot beams that do not land within the target area cannot be detected by the aiming device. This becomes particularly problematic if, for example, a time limit is to be triggered with the firing of the first shot beam of a firing round or a series of shot beams.

[0029] The present invention, for example, can remedy this situation and counteract the problem: Depending on the physical configuration, such as the aperture angle with which the shot meta-information is transmitted, the area outside the target area can also be recognized as a fired shot. This leads to the target area being reduced in size until the "miss" zone of the target area no longer exists. The functionality of the "miss" zone can then be simulated solely based on received shot meta-information. In this way, for example, costs and / or size can be reduced through a simplified design of the aiming device, while the functionality of the aiming device can be maintained and / or improved through an extended detection range of the aiming device.

[0030] Furthermore, the shot metainformation can be used generally to identify shot rays that did not hit the target area of the aiming device as fired shots in certain areas.

[0031] Several possibilities for transmitting and / or receiving the shot beam and the shot metainformation are presented below: In one embodiment of the invention, it is possible in principle for the transmitting device to transmit the shot beam and the shot metainformation using the same transmission means, for example, as a laser beam. For example, the shot beam and the shot metainformation can have different codings, different lengths, or the like, so that the receiving device can distinguish a shot beam from a shot metainformation.

[0032] Advantageously, the transmitting device is configured to transmit the optical shot beam on a first transmission channel and to transmit the shot meta-information on a second transmission channel, the second transmission channel differing from the first transmission channel in at least one transmission property, and the receiving device is configured to receive the shot beam on the first transmission channel and to receive the shot meta-information on the second transmission channel. The different transmission channels enable a clear distinction between shot meta-information and shot beam. Thus, for example, mutual interference between the shot beam and shot meta-information can be avoided or reduced, and compatibility of the shooting device with aiming devices that are not configured to receive the meta-information can be maintained.

[0033] There are many possibilities for configuring the different transmission channels: One advantageous embodiment provides for the at least one transmission characteristic to be formed by the first transmission channel and the second transmission channel having different transmission frequencies or transmission wavelengths. A transmission frequency or transmission wavelength is, for example, the frequency at which the transmitting device transmits or the receiving device receives, or a wavelength at which the transmitting device transmits and the receiving device receives. For example, the transmission frequencies / transmission wavelengths can be in the visible light range, the invisible light range (e.g., infrared), or the radio range.

[0034] It is also conceivable that the transmission characteristics of the transmission channels differ because the transmission takes place on a different transmission medium or the transmission of the transmission channels takes place on different transmission media. For example, the metadata can be transmitted via ultrasound.

[0035] The first transmission channel and the second transmission channel can also differ in terms of their carrier frequencies. Carrier frequencies refer to a signal that is modulated onto a transmission medium (e.g., light) for data transmission. For example, the carrier frequency of the first transmission channel for transmitting the shot beam is in a range of approximately 35-45 kHz. Particularly preferably, the first transmission channel has a carrier frequency of 40 kHz. The carrier frequency of the second transmission channel can be lower than the carrier frequency of the first transmission channel. The carrier frequency of the second transmission channel is preferably higher than the carrier frequency of the first transmission channel. The carrier frequency of the second transmission channel is, for example, 56 kHz.

[0036] The at least one transmission property can also be formed by the first transmission channel and the second transmission channel providing data transmission at different wavelengths. For example, the wavelength of the first transmission channel for the shot beam can be in the range of 650 nm, while the wavelength of the second transmission channel for the shot metainformation can be in a different range, for example, in particular greater than the wavelength of the first transmission channel. For example, the wavelength for data transmission on the second transmission channel is 800 nm.

[0037] It is advantageous if the first transmission channel is designed and provided for data transmission in the light range, in particular in the red light range. For example, the first transmission channel can provide for transmission with a laser signal using a red laser.

[0038] It is preferred if the second transmission channel is configured for data transmission outside the visible light or radio range. For example, data transmission in the infrared range or via radio, etc., is advantageous.

[0039] If the first and second transmission channels cover different frequency ranges, aiming devices that are not designed to receive the shot meta-information, e.g. conventional aiming devices, are not disturbed by the second transmission channel because they are not designed or sensitive to receive information on the second transmission channel.

[0040] The at least one transmission characteristic can also be formed by the first transmission channel and the second transmission channel providing data transmission with different modulations. For example, it is advantageous if the first transmission channel provides amplitude-shift keying (ASK) modulation. The second transmission channel can, for example, provide frequency-shift keying (FSK) modulation.

[0041] One embodiment of the invention can provide that the transmitting device for transmitting the shot beam and / or the shot metainformation is configured as a laser beam. In this configuration, the receiving device is accordingly configured to receive the shot beam configured as a laser beam and / or the shot metainformation configured as a laser beam. Thus, in principle, both the shot beam and the shot metainformation can be transmitted and received as a laser beam. It is also possible for only the shot beam to be transmitted as a laser beam, but for the shot metainformation not to be transmitted as a laser beam.

[0042] The transmitting device can use the same physical devices for transmitting, and the receiving device can use the same physical devices for receiving, for example, on the first and second transmission channels. To distinguish between the transmission channels, a modulation of the shot signal and the shot metainformation is advantageously set, for example. However, it is also possible to distinguish between the shot beam and the shot metainformation by setting a time offset between the shot beam on the one hand and the shot metainformation on the other.

[0043] However, it is also possible that different physical devices are provided dedicated to the shot signal and the shot metainformation.

[0044] For example, the transmitting device can comprise a shot transmitting device for transmitting the shot beam and an information transmitting device, separate from the shot transmitting device, for transmitting the shot metainformation. For example, it is possible for the shot transmitting device and the information transmitting device to be arranged at different locations on the firing device. For example, the shot transmitting device can be arranged directly on or in the barrel component of the firing device. The information transmitting device, in turn, can be arranged, for example, on the handle of the firing device or on an outer circumference of the barrel component. The shot transmitting device comprises, for example, a laser diode.

[0045] It is further advantageous if the receiving device has a shot receiving device for receiving the shot beam and an information receiving device, separate from the shot receiving device, for receiving the shot metainformation. For example, the shot receiving device and the information receiving device can be arranged at different locations on the targeting device. For example, the shot receiving device is assigned to the target area and detects shot beams that impact the target area. The information receiving device is preferably assigned to areas outside the target area. However, it is readily possible for the information receiving device to have a reception area that is not limited to areas outside the target area, but also encompasses all or part of the target area.

[0046] It is advantageous if the shot transmitting device and the information transmitting device transmit on different transmission channels and / or the shot receiving device and the information receiving device are configured to receive on these different transmission channels. For example, an advantageous embodiment of the invention provides that the shot transmitting device is configured to transmit the optical shot beam on a first transmission channel and the information transmitting device is configured to transmit the shot metainformation on a second transmission channel, wherein the second transmission channel differs from the first transmission channel in at least one transmission property, and that the shot receiving device is configured to receive the shot beam on the first transmission channel and the information receiving device is configured to receive the shot metainformation on the second transmission channel.

[0047] The shot metainformation can perform a variety of functions and / or be configured in a variety of ways: For example, one advantageous variant provides that the shot metainformation comprises or is formed by identification information identifying the shot sent by the transmitting device and / or the firing device. For example, the identification information can comprise or be a serial number of the firing device. Furthermore, the identification information can identify an operator assigned to the firing device. For example, if the firing device has information about which operator is currently operating the firing device, the firing device can use the identification information to send data about the operator, for example their name, participant number, or the like, to the aiming device as shot metainformation.

[0048] Furthermore, the shot meta-information may also include information about an operating action of an operator of the firing device in connection with the triggering of the shot beam, e.g. a speed with which a trigger of the firing device was actuated and / or a movement of the firing device triggered by the operator.

[0049] Furthermore, the shot metadata can also contain information about the operator, such as their name, participant number, pulse, body temperature, and the like. It is also possible to send identification information that uniquely identifies the operator and serves to identify data associated with the operator. Such data can be stored in a storage device to which the aiming device is connected. The aiming device can, for example, forward the identification information to the storage device. For example, storage in a cloud or the like is possible.

[0050] In principle, it is possible for the transmission device to transmit the shot metainformation to overlap or coincide with the shot beam. Particularly if the shot beam is transmitted as an optical beam, while the shot metainformation is not transmitted optically, for example, via radio, interference between the shot metainformation and the shot beam can be avoided even with simultaneous transmission.

[0051] However, it is advantageous, and particularly to avoid interference, if the transmitting device is designed and provided to transmit the shot metainformation at a predetermined and / or adjustable time interval from the shot beam. For example, after a final transmission pulse of the shot beam has been transmitted, the transmitting device or the shooting device waits a predetermined time before transmitting the shot metainformation.

[0052] It can be provided that the transmitting device for transmitting a shot beam is designed such that it only transmits the shot beam once the transmission of shot meta information from a previous shot beam from the transmitting device has been completed. Therefore, the transmitting device waits for the complete transmission of shot meta information before transmitting a subsequent shot beam. For example, a trigger mechanism of the firing device is blocked until the shot meta information of a previously transmitted shot beam has been finally transmitted. In practice, however, this problem will rarely arise, since an operator needs time to operate the firing device before being able to trigger another shot beam.

[0053] However, it is also possible for the firing device to allow the firing of a new shot beam while sending shot meta information for a previously fired shot beam. Thus, firing shot beams always has priority.

[0054] A preferred concept provides that the targeting device has a feedback transmitting device for transmitting at least one piece of feedback information to the transmitting device, and the transmitting device has a feedback receiving device for receiving the feedback information. The feedback information comprises, for example, an acknowledgment of the receipt of shot metainformation. Thus, for example, a registration dialog between the shooting device and targeting device is possible, in which the shooting device registers itself with the targeting device. It is advantageous if the feedback transmitting device and the feedback receiving device communicate via the second transmission channel and / or the transmission channel for the shot metainformation and the feedback information is the same.

[0055] Advantageously, the firing device registers with the targeting device using the firing metainformation so that the targeting device can assign itself to itself the firing beams received from the firing device. For example, the firing device can use the firing metainformation to send an identifier identifying the firing device to the targeting device, which identifier is stored by the targeting device. If firing beams are subsequently sent with firing metainformation containing the firing device's identifier, the targeting device can assign the firing beams to the firing device. It is possible for the targeting device to acknowledge receipt of the identifier using the feedback information, but this is not absolutely necessary.

[0056] The shot beam and / or the shot metainformation are preferably configured as digital data. The data format of the shot beam and the shot metainformation are preferably different.

[0057] It is also advantageous if the shot metainformation is encoded, in particular if it includes a security code and / or verification code. A CRC code, for example, is possible as a security code or verification code. It is particularly advantageous if the security code or verification code allows for error correction, for example, a so-called Error Correction Code (ECC).

[0058] According to the invention, the transmitting device is configured to transmit the shot beam with a first aperture angle and the shot meta-information with a second aperture angle that is larger than the first aperture angle. The shot beam thus has a greater directivity and a smaller scattering compared to a transmission beam with which the transmitting device transmits the shot meta-information. Thus, the shot beam can be transmitted in a targeted manner to the target area, while areas adjacent to the target area are also suitable for receiving the shot meta-information.

[0059] Advantageously, the aperture angle with which the firing device transmits the shot metainformation is dimensioned such that only the aiming device assigned to the firing device can receive the shot metainformation if the aiming device has a predetermined longitudinal distance from the firing device assigned to it and a predetermined transverse distance from a neighboring aiming device. The transverse distance and the longitudinal distance are specified, for example, by competition rules and / or minimum distances. The transverse distance is the distance between neighboring aiming devices. The longitudinal distance is the distance between an aiming device and the firing device assigned to it.

[0060] Furthermore, it is possible for the receiving device to receive the shot metainformation in the area of the target area. One embodiment may even provide that the receiving device can receive the shot metainformation exclusively in the area of the target area.

[0061] However, it is advantageous for the receiving device to be sensitive to the shot metainformation even outside the target area. For example, if the aperture angle of the shot beam is smaller than the aperture angle at which the firing device transmits the shot metainformation, an advantageous embodiment of the invention provides that the receiving device has at least one information receiving device for receiving the shot metainformation with a reception range outside the target area. For example, a receiving antenna, an infrared receiver, or another receiving means of the receiving device can be arranged next to the target area.

[0062] Advantageously, the firing device and / or the aiming device comprise a communication device, in particular a network interface, in particular a WLAN and / or Bluetooth interface. Thus, for example, the firing device and the aiming device, or even just one of them, can communicate via the network interface with, for example, an evaluation unit or a server. Via the network interface, the aiming device can, for example, transmit data determined based on the shot metainformation or the shot metainformation itself to the evaluation unit or the server.

[0063] Exemplary embodiments of the invention are explained below with reference to the drawings. They show: Figure 1 shows a schematic representation of a system according to the invention comprising a firing device and a targeting device, Figure 2 shows a temporal scheme when sending a firing beam and a firing meta-information by the firing device according to Figure 1 , Figure 3 a functional representation of the firing device and the aiming device according to Figure 1 Figure 4 shows a schematic representation of a communication between the firing device and the aiming device of the system, and Figure 5 shows an arrangement of several firing devices and aiming devices.

[0064] A system 10 according to the invention comprises a firing device 20 and a targeting device 40.

[0065] The firing device 20 comprises, for example, a pistol-like housing 21 with a handle 22, which is provided and configured for gripping by an operator. A barrel 23 in the manner of a pistol barrel protrudes from the handle 22, which an operator of the firing device 20 directs toward a target surface 43 of the aiming device 40 in order to fire an optical shot beam SU onto the aiming device 40 by pulling a trigger 24.

[0066] The aiming device 40 comprises a housing 41, on the front side 42 of which the aiming surface 43 is arranged.

[0067] The front side 42 of the aiming device 40 is configured in the manner of a target 44 or has a target 44. The target 44 or the front side 42 comprises the target surface 43. For example, the target surface 43 has a central region 43Z surrounded by an edge region 43R.

[0068] For example, a shot beam SU receives a higher score if it hits the central area 43Z than if the shot beam SU hits the edge area 43R. The shot beam SU is not scored if it does not hit the target area 43, for example, if it hits a reception area 42A outside the target area 43 of the aiming device 40 or completely misses the aiming device 40.

[0069] The firing device 20 comprises a transmitting device 25 with which the firing beam SU can be transmitted. In particular, the transmitting device 25 comprises a firing transmitting device 26, which is provided for transmitting the firing beam SU.

[0070] The shot beam SU is, for example, a laser beam, thus a directed beam. For example, the shot transmission device 26 has a small aperture angle Δ26 of less than 1° with which it transmits the shot beam SU. If the transmission device 26 is, for example, a laser transmission device, the aperture angle is particularly small, so that such an aperture angle is also referred to as divergence. Preferably, the aperture angle or divergence of the shot transmission device 26 is 0.006 degrees. The aperture angle Δ26 or the divergence can therefore be, for example, 0.1 mrad (mrad = milliradian).

[0071] The shot transmitting device 26 comprises, for example, an optical laser, in particular a laser diode.

[0072] The shot beam SU contains a pulse sequence SPF, which includes, for example, initialization pulses, etc. Preferably, the shot beam SU is a standardized shot beam, i.e. the length and sequence of the pulses of the pulse sequence SPF is defined by a norm or standard.

[0073] The firing device 20 comprises a controller 30 for generating the pulse sequence SPF. The controller 30 comprises, for example, a processor 31, a memory 32, and a program 33 stored in the memory 32 and containing program code executable by the processor 31 for generating the firing beam SU and for providing other functions that will be explained below. Further programs or program parts, in particular for generating the firing metainformation MI explained below, could easily be provided in the firing device 20. The processor 31, memory 32, and program 33 can also easily be integrated together in a microcontroller or the like.

[0074] The aiming device 40 comprises a receiving device 45 for receiving the shot beam SU, in particular the pulse sequence SPF. The receiving device communicates with an evaluation device 50 of the aiming device 40. The evaluation device 50 comprises, for example, a processor 51 and a memory 52 in which a program 53, for example an evaluation program, is stored, the program code of which is executable by the processor 51. The processor 51, memory 52, and program 53 can easily be integrated together in a microcontroller or the like.

[0075] The receiving device 45 comprises, for example, a shot receiving device 46 whose reception range corresponds to the target surface 43. Thus, the shot receiving device 46 can detect shot rays SU impinging on the target surface 43.

[0076] It is preferred that the shot receiving device 46 be able to detect which sub-areas of the target surface 43 are hit by a respective shot beam SU, for example, the central area 43Z or the edge area 43R. Thus, the aiming device 40 can represent, for example, a so-called precision target. However, it would also be sufficient if the aiming device 40 could only detect whether the target surface 43 was hit by the shot beam SU or not.

[0077] In order, for example, to identify the firing device 20 at the aiming device 40 and / or to identify a respective firing beam SU at the aiming device 40, the firing device 20 has an information transmission device 27 with which the aforementioned firing meta-information MI can be sent.

[0078] The information transmitting device 27 forms a component of the transmitting device 25.

[0079] To receive the shot metainformation MI, the aiming device 40 has an information receiving device 47, which forms a component of the receiving device 25.

[0080] The information transmitting device 27 transmits on a transmission channel SK2, which differs from a transmission channel SK1, on which the shot transmitting device 26 transmits the shot beam SU, in at least one transmission characteristic. For example, the transmission channel SK1 is generated by a laser with a preferred wavelength of 650 nm, i.e., the shot beam SU is transmitted as an optical laser beam. The transmission channel SK2, on the other hand, is a channel generated by an infrared light-emitting diode, for example, with a wavelength of 850 nm, so that the shot receiving device 46 can receive the shot beam SU, but not the shot metainformation MI.

[0081] For example, the shot metainformation MI includes digital data, which is represented as a pulse sequence MPF.

[0082] Different transmission channels SK1 and SK2 can also be formed by, for example, modeling the pulse sequence SPF of the shot beam SU differently than the pulse sequence MPF of the shot metainformation MI.

[0083] The aiming device 40 has an information receiving device 47 for receiving the shot metainformation MI. The information receiving device 47 can receive the shot metainformation MI, but not the shot beam SU.

[0084] For transmitting the shot meta-information MI, the information transmitting device 27 has an aperture angle O27 that is greater than the aperture angle O26. For example, the aperture angle O27 is 2° to 4°. Accordingly, the information receiving device 47 can receive the shot meta-information MI not only in the area of the target surface 43, but also in areas outside the target surface 43 on the target plate 44, for example, the reception area 42A.

[0085] For example, in the event that one of the information receiving devices 47 is covered, several information receiving devices 47 can be arranged on the target 44, as shown in Figure 1 indicated. Several information receiving devices 47 contribute to the transmission reliability and better reception quality of the shot metainformation MI.

[0086] In order to obtain, in addition to the inherently secure information transmission of shot beam SU and shot metainformation MI via different transmission channels SK1 and SK2, a higher degree of certainty that, on the one hand, the shot beam SU is not disturbed by the shot metainformation MI and, on the other hand, the shot metainformation MI is not disturbed by the shot beam SU, it is advantageous if the firing device 20 first transmits the shot beam SU, for example, during a transmission duration TS, then waits a waiting time TW and only then transmits the shot metainformation MI. For example, the transmission duration of the shot metainformation MI is a time TI. The diagram according to Figure 2 that even after the shot meta-information MI has been sent, a pause time is advantageous, for example a pause time SP, before the firing device 20 releases the trigger 24 to send another shot beam SU.

[0087] The pause time is advantageously short, so that the firing device 20 is quickly ready to fire another shot beam. It should be noted that the shot metainformation MI only requires a very short transmission time anyway, so that the firing device 20 is quickly ready to fire another shot beam.

[0088] A trigger pulse AB, which an operator can trigger by pulling the trigger 24, lasts, for example, a time period TA. To detect the trigger pulse AB, the firing device 20 has, for example, a sensor 34.

[0089] Triggered by the trigger pulse AB, the controller 30 triggers the shot beam SU, thus controlling the shot transmitting device 26 to transmit the shot beam SU. The controller 30 then waits the waiting time TW before controlling the information transmitting device 27 to transmit the shot metainformation MI.

[0090] The aiming device 40 can communicate the shot metainformation MI to an evaluation device 90. The evaluation device 90 is configured, for example, as a central server or is arranged or provided on a central server.

[0091] For communication with, for example, the evaluation device 90, the target device 40 has, for example, a communication device 55, in particular a network interface, for example a WLAN interface or LAN interface, Bluetooth interface, or the like. A data connection DV1 between the evaluation device 90 and the target device 40 is shown as an example.

[0092] The firing device 20 can also advantageously have such a communication device, for example, a communication device 35. The communication device 35, for example, a LAN interface or a WLAN interface or Bluetooth interface or the like, in any case advantageously a network interface, can be configured, for example, for direct communication between the firing device 20 and the evaluation device 90 via a data connection DV3. For example, the firing device 20 can report to the evaluation device 90 that the firing metainformation MI has been sent to the targeting device 40 via the communication device 35. As a result, the selection device 90 can, for example, receive information that the firing device 20 is registering with the targeting device 40, which will be described in more detail below.

[0093] However, a data connection DV2 with, for example, a switch 98 is also possible via the communication device 55. The target device 40 can be connected to a network 99, for example, the Internet, via the switch 98.

[0094] The evaluation device 90 has, for example, an evaluation program 96 which is stored in a memory 95 and can be executed by a processor 94 in order to process the shot metainformation MI or data derived therefrom.

[0095] The evaluation device 90 can in principle also form a component of the aiming device 40.

[0096] It is also possible for the evaluation device 90 to be connectable or connected to at least two, preferably multiple, targeting devices 40 in order to evaluate the respective shot metainformation MI received by these targeting devices 40. For example, the targeting devices 40 can be connected to the evaluation device 90 via a network.

[0097] Thus, it is also possible for a targeting device 40 not to have an evaluation device 90, but to interact with a so-called external evaluation device 90, e.g., a targeting device 40X corresponding to the targeting device 40, which interacts with a depicted firing device 20X, which corresponds in principle to the firing device 20. The targeting device 40A is connected to the evaluation device 90 via a data connection DV1X.

[0098] The evaluation device 90 has an input interface 93, for example, a keyboard, and an output device 92, for example, a screen 91, loudspeaker, or the like. However, it is also possible for the evaluation device 90 not to have its own keyboard or the like, but rather to be remotely operable and / or serviceable, for example, via the Internet or the like. The evaluation device 90 then naturally also does not require an output interface in the sense of a screen or the like. It is sufficient for such an evaluation device 90 if it has, for example, a network interface.

[0099] Using the evaluation device 90 and its evaluation program 96, an operator can, for example, evaluate the shot beams SU delivered by the firing device 20 to the aiming device 40. The assignment of the shot beams SU to the firing device 40 is readily possible, for example, by more closely identifying the shot beams SU using the respective shot metainformation MI.

[0100] Thus, several firing devices 20A, 20B and 20C, which are basically similar to the firing device 20, can be provided, each of which is assigned a targeting device 40A, 40B and 40C, which corresponds to the targeting device 40.

[0101] Each of the aiming devices 40A, 40B, 40C can communicate with the evaluation device 90 via the network 99 or directly, wherein the evaluation device 90 can assign the shot beams SU emitted by the firing devices 20A, 20B and 20C to the respective firing devices 20A, 20B and 20C on the basis of the associated shot meta information MI.

[0102] At this point, it should be mentioned that, for example, two or more firing devices 20A, 20B, 20C can also be assigned to a single one of the aiming devices 40A, 40B, or 40C, which can then assign the firing beams SU directed at them to a respective firing device 20A, 20B, 20C based on the firing metainformation MI accompanying the respective firing beam SU. Thus, one aiming device 40A, 40B, or 40C can serve as an aiming device for two or more firing devices 20A, 20B, 20C.

[0103] A communication of shot metainformation MI can also be part of a registration procedure, which in Figure 4 is indicated schematically. For example, the information transmitting device 27 of the firing device 20 transmits a firing metainformation MI2 as a registration message or registration information AI. The firing metainformation MI2 comprises, for example, a header HD, a data part DA, and a verification code CRC, which, so to speak, secures the registration information or the firing metainformation MI2, for example, against mistransmissions or incorrect transmissions. The verification code CRC can, for example, be a typical CRC code, for example, a redundancy check or the like.

[0104] It is also possible for the CRC verification code to enable error correction, i.e., for the aiming device 40 to recover data from the shot metainformation MI2 using the CRC verification code or a correction code ECC provided instead of or in addition to the CRC verification code. This ensures the data integrity of the data part DA or at least ensures its integrity with a higher probability. The data part DA contains, for example, an identifier ID2, for example, a unique number and / or a unique name of the shooting device 20, thus additional information ZI.

[0105] In itself, it would be sufficient for the aiming device 40 to receive the additional information ZI, thus the identifier ID2, as part of a registration of the firing device 20 with the aiming device 40, so that the firing device 20 is registered with the aiming device 40.

[0106] However, it is advantageously provided that the aiming device 40 of the firing device 20 acknowledges the registration, so to speak, and / or establishes a clear assignment of the firing device 20 to the aiming device 40, in that the firing device 20 also knows, so to speak, which aiming device 40 is assigned to it.

[0107] The aiming device 40 advantageously transmits a feedback information AK to the firing device 20 using a feedback transmission device 48. The feedback information AK is, for example, a message with a header HD, a data part DA, and a verification code CRC. The data part DA contains, for example, an identifier ID4, in particular a unique identifier, of the aiming device 40.

[0108] The firing device 20 receives the feedback information AK using a feedback receiving device 28. For example, the firing device 20 and the aiming device 40 store the identifiers ID4 and ID2, respectively, in their respective memories 32, 52. As a result, the firing device 20 is registered with the aiming device 40, so that shot beams SU sent by the firing device 20 can be assigned by the aiming device 40 to the firing device 20 and thus evaluated and / or sent to, for example, the evaluation device 90.

[0109] This prior registration procedure is advantageous, but not mandatory. It would also be possible, for example, as in Figure 4Also shown schematically, the firing device 20 transmits the firing beam SU with and without a prior registration procedure and the firing meta-information MI in connection with the firing beam SU, for example, with the time delay or waiting time TW. The firing meta-information MI is configured, for example, as a message SI containing a header HD, a data part DA, and a verification code CRC. The data part DA can contain, for example, the identifier ID2 so that the aiming device 40 can assign the previously transmitted firing beam SU to the firing device 20.

[0110] The aperture angle O27 is preferably selected to be so small that the shot meta-information MI can only be received by one aiming device 40 of an arrangement of several aiming devices 40, for example the aiming devices 40A, 40B and 40C. This is in Figure 5indicated schematically. Thus, if, for a given longitudinal distance DL between a firing device 20 and the aiming device 40 assigned to the firing device 20, a firing beam SU is emitted which is directed at the target surface 43 of the aiming device 40, the aperture angle O27 is selected such that the firing metainformation MI can only be received by the aiming device 40 assigned to the firing device 20, i.e., for example, by the aiming device 40B if it is assigned to the firing device 20B and has a transverse distance DQ from adjacent aiming devices 40A and 40B, provided, for example, for a shooting competition.
