Description

The invention relates to a device for monitoring combat vehicles separated by parties, in particular battle tanks, during practice shooting with simulated shots, in which a laser is arranged in each combat vehicle, which, when the firing button of the weapon is actuated, emits at least one light pulse in a by the weapon or the optical target device emits a specified direction and in which devices for receiving an incident light pulse are arranged on each combat vehicle, which are connected to display devices arranged on the combat vehicle for the arrival of the light pulse.

Devices for simulating shots during practice shooting with battle tanks, in which light pulses emitted by a laser arranged in the battle tank are used for the shot simulation, are known per se (see e.g. DE-A 31 13 068).

A device for combat and shot simulation is also known, in which wireless remote-controlled scale models of vehicles are used, which serve as an attacking target. In this known device, too, light pulses emitted by a laser are used to simulate shots and the target models are able to signal a hit when the light pulse strikes (see DE-A 32 01 925).

There are also devices for monitoring a combat vehicle, in particular a battle tank, in training use from a control center with a television recording device which is coupled to an aiming or observation device of the combat vehicle via an optical adaptation device and via an image transmission link with a television playback device arranged in the control center is connected (see for example DE-A 30 23 516, DE-A 30 23 518, DE-A 30 23 553).

The object underlying the invention was to provide a device for monitoring combat vehicles, in particular battle tanks, during practice shooting with simulated shots, in which each combat vehicle has the features described in the preamble of claim 1 and with the help of a control center all combat vehicles participating in the practice shooting can be monitored separately by parties and in particular each of the combat vehicles involved which fires a shot and / or prepares to fire a shot can be monitored specifically.

This object is achieved according to the invention with the features from the characterizing part of patent claim 1.

Advantageous embodiments of the device according to the invention are described in the subclaims.

The invention basically consists of a combination of a device for simulating shots with a device for monitoring a combat vehicle from a control center.

As described in detail below using an exemplary embodiment, it is possible with the device according to the invention to continuously monitor a specific combat vehicle from a predetermined group, for example one of the two fighting parties, during the training deployment. For example, this can be the lead armor of the two parties. The monitoring can then take place in such a way that the images of the television recording devices are constantly transmitted, those of the television recording devices are recorded, which are assigned, for example, to the target or observation device operated by the gunner or commander in the lead tank. Of course, as described in DE-OS 30 23 516, the commander or the gunner of the lead tank can be monitored alternatively and in this way, or mixed images can be transmitted, as described for example in DE-OS 30 23 518.

As soon as another combat vehicle in the specified group fires a shot, an image appears on the television playback device in the control center for a predetermined period of time, for example three seconds, that comes from the television recording device that is assigned to the target or observation device of the combat vehicle firing the shot . After the specified time has elapsed, the image from the lead tank reappears on the television display device.

With the aid of the device according to the invention, it is possible to monitor the activities of the combat vehicles of both parties and in particular the mutual firing of shots in all phases of the practice shooting from the control center.

If the combat vehicles are equipped with system-specific distance measuring lasers, these can be used in a manner known per se for firing simulation. It may be advisable to take precautions so that the distance measuring function can be distinguished from the shooting function of the laser. This can be done, for example, according to the features from claims 4 or 5. A particularly simple one To be realized embodiment of the device according to the invention is described in claim 6. In this embodiment, a distinction between the two laser functions is not necessary since the light pulse is only emitted when the fire button is actuated. In this simple and particularly inexpensive embodiment, the gunner does not yet receive any information about the real distance at the time of the distance measurement. It is only displayed when the shot is actually fired. The conversion of the fire control system is very simple in this embodiment. It is only necessary to ensure that a command is sent to the fire control system when the distance sensor is pressed, in which a distance measurement is simulated but not carried out, and that a command is carried out to the fire control system when the fire button is pressed and the distance measurement is carried out and thus the shot is simulated. This can be done using a simple adapter, for example.

Of course, the shot simulation can be carried out by a special laser according to claim 3, both in combat vehicles with a distance measuring laser and in combat vehicles without the system's own laser. In this embodiment, if a system-specific distance measuring laser is available, it is possible to have the laser used for the shot simulation work with a different wavelength. In this way, the different functions of the laser can be clearly separated and the device for receiving and / or reflecting incident light pulses can be designed so that only real hits are registered. The special laser is expediently designed so that the divergence of the laser beam is the same as in a conventional distance measuring laser and is approximately 0.5⁻ according to the weapon and the ammunition scatter.

If an active combat vehicle is to be monitored not only immediately when the shot is fired, but already during the preparation of the firing, the switching over of the image generated on the television display device can also take place when the range finder is actuated (claim 7).

If a shot is fired from two combat vehicles of the same party at the same time or in quick succession within the predeterminable period of time, during which a switch is made to the image assigned to the shooting combat vehicle, the image assigned to the second shooting combat vehicle can be stored and then switched to the television playback device concerned (claim 8). .

It is also advantageous if all video radio signals fed to the television playback devices are stored in a recording device for later reconstruction of the practice shooting. In order to reconstruct the exact chronological sequence, it is very expedient if the video radio signals assigned to the different parties are recorded on a common data carrier that has two separate tracks, so that no delays in the chronological sequence can occur (claim 9).

It is also advantageous if each vehicle one of the two parties can be selected from the control center in such a way that the image delivered by its target or observation device appears on the television display device concerned (claim 10). In principle, it is expedient if the system data of the combat vehicles in question are faded into the images appearing on the television playback devices in a manner known per se.

The hits can be displayed in a manner known per se on the combat vehicle hit, in which devices for receiving an impinging light pulse are arranged on each combat vehicle, which are connected to display devices, for example flashing lights arranged on the outside. It is expedient here if the control signal driving the switching device is also sent from the combat vehicle hit, so that the image of the hit combat vehicle also appears on the corresponding television display device in the control center (claim 13) and it can also be ensured that in a hit combat vehicle the fire button is blocked (claim 12), so that this combat vehicle can no longer actively participate in the operation.

In a particularly advantageous embodiment of the device according to the invention, a light pulse is emitted both for distance measurement and for shot simulation, and an additional signal ensures that a light pulse emitted for distance measurement cannot trigger a hit display (claim 14). For this purpose, a coded shot signal is emitted via an additional radio transmitter arranged in the control center, which is received by additional radio receivers arranged in the combat vehicles. The firing of the shot signal is triggered by the control signal which drives the switching devices when a simulated shot is fired. A hit notification is only given if a light impulse and a shot signal arrive on a combat vehicle hit within a specified period of time. Of course, the shot signals are coded differently for the combat vehicles assigned to different parties. Basically, the shot signal can also be delivered synchronously with a shot release signal given to the shooting combat vehicle in a known manner.

This embodiment has the great advantage that distance measurement and shot simulation can be clearly distinguished. The distance measurement can then again be carried out and displayed together with the shot simulation or can be superimposed as data on the television playback devices of the control center. In this way it is also possible to check the first distance measurement.

This embodiment also opens up the possibility of reactivating a struck combat vehicle with a further coded radio signal emitted by the additional radio transmitter of the control center and thus making it operational again (claim 15).

As already stated above, "combat vehicles" can be understood to mean battle tanks in the sense of the invention. However, it is entirely possible to use the device according to the invention in other combat vehicles, and in particular it can be used in a mixture of different vehicle types, for example when using battle tanks and helicopters together. In the case of a type of combat vehicle, of which only a few combat vehicles are involved, the above-mentioned possibility of reactivation, for example in the case of helicopters, can play a special role.

The device according to the invention allows a complete monitoring of the fighting from the control center, in particular by means of the preferred embodiments with regard to the display of those taken Combat vehicles are able to carry out precise situation analyzes, for example duels or surprise successes can be monitored.

In Fig. 1, the devices are shown on a total of six main battle tanks. Three main battle tanks Aa, Ab and Ac are said to belong to one party, while the three other main battle tanks Ba, Bb and Bc are to belong to the other party B. Of course, each of the two parties A and B can also have a larger number of battle tanks. For example, monitoring can easily be carried out on e.g. up to 20 vehicles can be expanded.

Of the main battle tanks shown in FIG. 1, the main battle tank Aa and the main battle tank Ba were the lead tanks.

The main battle tank equipment is the same and the same reference numbers are given in FIG. 1 for the same device parts. Everyone who has battle tanks an observation or target device 1, to which a television camera 3 is coupled via an optical adaptation device 2. The television camera 3 is connected to a telemetry transmitter 4. Each tank has a fire control system 6 with a fire button 6a and a distance measuring button 6b. The fire control system 6 is connected to a distance measuring laser 5 via a control device 7. Furthermore, each tank has a device 8 for receiving light pulses, which is connected via an evaluation unit 9 on the one hand to a display device 10, for example a flashing light, and on the other hand to the control device 7.

The control device 7 shown in somewhat more detail in FIG. 5 and described in more detail below has various functions. On the one hand, it causes the laser 5 to emit a first light pulse for distance measurement when the distance measuring button 6b is actuated. At the same time, a control signal can already be generated which is modulated onto the radio signal emitted by the telemetry transmitter 4. When the fire button 6a is actuated, the laser 5 is reactivated and a light pulse is emitted. At the same time, the control device 7 generates a control signal which is modulated onto the image radio signal emitted by the telemetry transmitter 4. Finally, the control device can also contain units 7b ', 7b''by means of which additional signals, for example for the transmission of system data, are inserted into the image signal to be transmitted. The control device 7 can also be supplied with signals which are supplied by the evaluation unit 9 when, as described further below, the device 8 for receiving light pulses receives a light pulse which indicates a hit on the vehicle. In this case too, the control signal is generated and fed to the telemetry transmitter 4.

In addition, the display device 10 is activated if a shot signal is received by an additional radio receiver 19 within a predetermined period of time, as will be explained in more detail below.

2 shows the part of the overall device arranged in the control center. There are two telemetry receivers 11a and 11b, which are connected to television playback devices 14a and 14b via the decoding and switching devices 12a and 12b, respectively. Furthermore, a storage device 13a or 13b is connected to the decoding and switching device 12a or 12b. In addition to the transmission images of the target and observation devices, a separate data image 15a or 15b appears on the screen of the television playback devices 14a or 14b, the position and size of which can be set as desired in the main picture. The data image can contain system data, for example displays about target distance, ammunition type and the like. The like. Furthermore, a time signal and a hit signal can be displayed.

The functions of the equipment parts arranged in the control center are controlled from keypads 16a and 16b. The device parts 11a, 12a, 13a, 14a are each assigned to party A shown in FIG. 1, while the device parts 11b, 12b, 13b and 14b are assigned to party B shown in FIG. 1. The images displayed by the two television playback devices 14a and 14b are simultaneously fed to a video recorder 17 and stored there on a common recording medium which has two tracks.

A radio transmitter 18 is also connected to the decoding and switching device 12a or 12b on arrival of a control signal at one of the telemetry receivers 11a and 11b emits a coded shot signal which is coded differently depending on which of the two telemetry transmitters the control signal was received.

The decoding and switching devices 12a and 12b contain a video logic, not specifically shown, which is constructed from devices known per se, by means of which the signals received by the telemetry receivers 11a and 11b are decoded and which controls commercially available video switches according to the control signals contained in the signals, via which the Signals are supplied to units 13a, 14a and 13b, 14b and 17 and 18, respectively.

Some details of the logical processing of the control signal in this context can be found in the circuit shown in somewhat more detail in FIG. 3. The devices 13a, 14a and 13b, 14b and 17 from FIG. 2 are not shown in FIG. 3 for the sake of a better overview. The devices U1a, 20a, 21a, 22a or U1b, 20b, 21b, 22b can be understood as being contained in the device 12a in FIG. 2. For this reason, the device parts containing the video logic and the video switches are drawn in FIG. 3 with 12a 'and 12b'. The In FIG. 3, OR gate 01 in FIG. 3 can be understood as being arranged within radio transmitter 18. When a control signal, which indicates a shot delivery, arrives at the telemetry receiver 11a, the decoding and switching device 12a ′ outputs a control signal to a modulator 20a via an AND gate U1a, if no signal is present at the second negated input of the AND gate U1a , which indicates that a corresponding control signal has already been received by the telemetry receiver 11b shortly before. The radio transmitter 18 is controlled by the modulator 20a via an OR gate 01 and transmits the coded shot signal. At the same time, the modulator 20a sends a blocking signal to the AND gate U1b for a predetermined period of time via a monostable multivibrator 22a, via which the decoding and switching device 12b 'connected to the telemetry receiver 11b is connected to a corresponding modulator 20b. In a corresponding manner, the radio transmitter 18 can be excited by the modulator 20b via the OR gate 0 to emit another coded shot signal. The modulator 20b is connected to the negated input of the AND gate U1a via a monostable multivibrator 22b.

Furthermore, it is possible to activate the modulator 20a or 20b from the reactivation buttons 21a or 21b in such a way that coded reactivation signals are emitted from the radio transmitter 18, which are described in more detail below Can be picked up by a radio receiver 19 arranged on a specific combat vehicle.

FIG. 4 shows how the shot signals and reactivation signals coming from the radio transmitter 18 of the control center are processed in the equipment parts of the combat vehicles. 4 in a simplified representation, the fire control system 6 according to FIG. 1 is not shown and assumed that the fire button 6a acts directly on the control device 7, which is shown here divided, the device 7a, for example, consisting of a relay or a commercially available electronic control device may consist of generating a control signal for the laser 5, while the device 7b, which may contain a commercially available modulator, generates the control signals supplied to the telemetry transmitter 4. The devices 7a and 7b can be understood as part of the device 7 in FIG. 1.

The devices 8 for receiving light pulses are connected to a memory 9b via a monostable multivibrator 9a and an AND gate U2. The second input of the AND gate U2 is connected to the radio receiver 19 via a decoder 9c. In addition, the radio receiver 19 is connected to the reset input of the memory 9b via a further decoder 9d. If a shot signal arrives at the radio receiver 19 within a period of time predetermined by the monostable flip-flop 9a after the arrival of a light pulse at the device 8, the AND gate U2 is permeable and a setting pulse is supplied to the memory 9b. As a result, the memory activates the display device 10. At the same time, the control device 7b is activated, which causes the transmission of the control signal by the telemetry transmitter 4 of the vehicle. Furthermore, a signal is fed to a negated input of a further AND gate U3. The firing button 6a is connected via the AND gate U3 to the control device 7a, which causes the laser 5 to emit a light pulse for the purpose of firing simulation. When the display device 10 is switched on, as can easily be seen from the drawing, it is no longer possible to emit a light pulse to simulate the shot.

If a reactivation signal is received by the radio receiver 19, the memory 9b is reset via the decoder 9d, the display device 10 is switched off again and the AND gate U3 is released.

In FIG. 5, the control device 7 according to FIG. 1 is shown somewhat more precisely for a better understanding. The fire control system 6 can be designed in a manner known per se in combat vehicles and not shown in more detail and generally contains a fire control computer and circuits connected to this fire control computer, for example safety circuits or circuits for entering a signal for ammunition selection. Fire control systems with a fire control computer are described, for example, in US Pat. No. 3,538,318 and US Pat. No. 3,739,152. A circuit for entering a signal of the ammunition selection in a fire control computer is the subject of US Pat. No. 4,125,055, while a circuit arrangement for securing electrically operated weapon systems is described in DE-OS 27 03 803.

When the fire button 6a or the distance measuring button 6b is actuated, the fire control system 6 sends signals via the lines 6a 'and 6b' and an OR gate 02 given to an AND gate U3 'with a negated input, which corresponds to the AND gate U3 according to FIG. 4. The control device 7a ′ can correspond to the control device 7a according to FIG. 4 and can be designed, for example, as a relay. A signal is emitted from the AND gate U3 'if there is no signal coming from the evaluation unit 9 (see FIG. 1) at the negated input. The signals coming from the evaluation unit 9 and the AND gate U3 'are simultaneously fed to a character insertion device 7b' via a data interface 7b ''. Furthermore, data can be fed from the fire control system 6 via a data line 6c, for example about target distance, ammunition type and readiness for fire, likewise via the data interface 7b ″ to the character insertion device 7b ′. The data interface and the character insertion device can be designed in a manner known per se on the market. Devices supplied by Bosch can be used here, for example, under numbers T1246 and T1245. The signals to be superimposed on the television picture and the control signals are fed via line 7c to the telemetry transmitter 4 from the character insertion device 7b '.

The mode of operation of the device shown in FIGS. 1 to 4 is described in summary below:
In normal operation of the practice shooting, i.e. as long as the firing button or the distance measuring button is not pressed in either of the battle tanks of parties A and B involved, the images appearing on the screens of the two television playback devices 14a and 14b are those of the targeting and observation devices 1 of the two lead tanks Aa and Ba are included. As already mentioned, both the image of the commander's optics and the image of the gunner's optics can be displayed in a mixed image. Corresponding system data can also already be displayed in data image 15a and 15b.

If, for example, the main battle tank from party A has picked up a target and wants to fight it, the distance measuring button 6b is first pressed in this main battle tank and the target distance is measured in the usual way. The control device 7 causes the control device 7 to give a control signal to the telemetry transmitter 4 of the main battle tank Ab, which causes the control center from the decoding and switching device 12a to now switch to the radio signal coming from the main battle tank Ab and on The image recorded by the target and observation device 1 of the battle tank Ab appears on the screen of the television playback device 14a. If the fire button 6a is now pressed in the main battle tank, the Distance measuring laser 5 sends a further light pulse to simulate a shot and sends a shot signal from the radio transmitter 18 in the control center. If a hit has been achieved, for example on the battle armor Bb of party B, this light pulse is picked up by the receiving device 8 on the battle armor Bb and, if the shot signal was simultaneously received by the radio receiver 19, the externally visible display device 10 in via the evaluation units 9 and 9a, 9b Activity set, which can also be observed on the screen of the television playback device 14a in the control center. At the same time, the image recorded by the targeting and observation device 1 of the main battle tank Bb appears on the screen of the television playback device 14b with system data superimposed.

After a predetermined period of time, for example after 3 seconds, the decoding and switching devices 12a and 12b switch over again and the images generated by the targeting and observation devices 1 of the lead armor Aa and Ba again appear on the screens of the television display devices 14a and Ba with system data superimposed . The device part A in FIG. 2 is thus ready for the next activity of one of the main battle tanks from party A.

The same processes take place analogously on the television playback devices 14b and 14a if one of the battle tanks from party B, for example the battle tank Bb, has picked up a target and fires a shot.

If, within the specified time period of 3 seconds after a shot was fired from the main battle tank Ab, another main battle tank of party A, for example the main battle tank Ac, picks up a target and comes to the shot, the decoding and switching device 12a does not initially switch, but the signals emitted by the telemetry transmitter 4 of the main battle tank Ac are fed from the telemetry receiver 11a via the decoding and switching device 12a to the memory 13a and stored there. After the expired period of 3 seconds, the signal stored in the memory 13a is then switched to the screen of the television playback device 14a and is also displayed on the screen for 3 seconds. The relationship between the time sequence of the displayed images can be read off at any time via the real-time information shown in the data image 15a. Of course, it is also possible to design the device in such a way that a plurality of image radio signals arriving in succession are stored in the memory 13a and then output again in the order in which they arrive.

The same processes take place analogously in the equipment part assigned to party B if the corresponding video radio signals are emitted by two battle tanks of party B within the specified period.

To monitor the entire action, regardless of the firing of the shot, it is possible to use the keypads 16a and 16b to select any of the battle tanks of parties A and B from the control center, the respective image of the targeting and observation device 1 of the battle tank in question then being opened appears on the screens of the television playback devices 14a or 14b.
