The invention relates to a device of the type specified in more detail in the preamble of claim 1. Such a device is known from DE-PS 17 28 222.

For certain operating conditions of anti-aircraft guns it is necessary to block the firing charge of the weapon if it is within a specific sector of their field of fire is located. In such a restricted area z. B. Residential Areas lie or operate their own combat troops, which are protected against unintentional fire should be.

For storing the angle values of the restricted area The gunner drives the gun a complete turn in the electronic memory by 360 °, which corresponds to 6400- (line), and continuously changes the elevation angle according to the locking contours. However, such programming is laborious, inflexible and imprecise, so that Safety surcharges must be made for the saved restricted area.

In contrast, the object of the invention is to provide a device of the type mentioned at the beginning create, which allows a simpler, more flexible electronic specification of the restricted area.

Fig. I shows a plan view in the A / invitcoene of a weapon, for example a gun. The weapon can be pivoted in azimuth and elevation around a pivot point which is in the middle of a 6400 full circle. The range within which the weapon can be fired is between 5600 and 8000 in the example shown, viewed in a clockwise direction. Of course, it is also possible to choose the range of the weft angle as desired, for example also from 4800- to 1600 ".

In the example shown, the weft angle range is subdivided into a total of four sectors I to IV, of which sector II is selected as the blocking sector. Instead of sector II, any other of the remaining sectors I, III or IV can also be selected as a blocked sector. The weapon is currently in a position illustrated by a dash-dotted line which, with the straight line connecting the pivot point and the 0 position, includes the clockwise wi.ikel / x .

The set angle values are shown, for example, on a luminous digital display of the relevant selector 1 up to 5 can be read (Fig. 2). In the example shown, voter 1 is on the?) Value 5600 ", voter 2 on the Value 6000, voter 3 to the value 0-, voter 4 to the value 400- and voter 5 to the value 800- discontinued. The opening angles of the individual sectors I to IV are in the example shown chosen to be the same size and are 400 ". Of course, the opening angles of the individual sectors 1 to IV can also be selected to be of different sizes. Furthermore, instead of the four sectors shown, I up to IV more or fewer sectors are also provided within the weft angle range; meanwhile four sectors I to IV are preferred, since such a choice results in a particularly simple structure of the Facilitates device according to the invention in digital form. Namely, as FIG. 1 shows, the Certain combinations of binary numbers can be assigned to individual sectors I to IV: Sector I die Binary combination OLLL, the sector II the binary combination LOLL, the sector III the binary combination LLOL and Sector IV the B'närkombination LLLO.

Furthermore, the part d; s 6400- circle outside of the The weft angle range is assigned the binary combination LLLL.

Each comparator K 1 to K 5 has two outputs, the first output of which carries an L signal when the complementary angle λ * at the first input of the

mi an L signal and a 0 signal at the second output 41 of the comparator K 1. At the outputs 32 and 42 of the comparator K 2 there is an L or 0 signal. while at the outputs 33 and 43 of the comparator ^ 3 an L or 0 signal, at the outputs 34 and 44

6ϊ of the comparator K 4 has an L or 0 signal and a 0 or L signal is present at the outputs 35 and 45 of the comparator K 5.

The conidarators K 1 and K 5 are coincidences

the. for example NAND gates. V 12. V 23. V34 and V45 followed in the same way. that in each case the first and the wide output of neighboring comparators are connected in increasing order to the inputs of a common coordinate element. In the example shown, the coincidence element V 12 is connected to the outputs 31 and 42 of the comparators K 1 and K 2 , while the coincidence element V 23 with the outputs 32 and 43 of the comparators K 2 and K 3, the coincidence element V34 with the outputs 33 and 44 of the comparators Ki and K 4 and the coincidence element V 45 is connected to the outputs 34 and 45 of the comparators K 4 and K 5. The non leading to a coincidence gate outputs of the comparators 35 and 4t K 1 and K 5 lead to a Logikeinrichtiing 7. reference to FIG. A, and is explained in more detail 5. The outputs 51 to 54 of the coincidence elements V12. V23. V34 and V 45 lead to a logic device 8. which is shown in FIG. 3 is shown in more detail. The output 81 of the logic device 8 is connected to a shot control device which z. B. works in such a way that when there is an L signal at output 81, the shot is blocked and when there is a 0 signal at output 81, the shot is released.

The structure of the logic device 8 is shown in FIG. 3 illustrated by way of example, it being understood that, instead of the selected structure, there are also other training options for the logic device 8. In the example shown, the logic device 8 has a total of four transmission paths 61 to 64. which are each connected to one of the associated outputs 51 to 54 of the coincidence elements V 12. V 23. V 34 or V 45, leather transmission path 61 to 64 is via a z. B. manually operable switching element 101, 102, 103 or 104 can be coupled to an input of a NAND element 82, the integrated output of which forms the output 81 of the logic device 8, the input of the NAND element 82 is also via a series resistor / ?, with connected to a positive DC voltage source illustrated by the circuit symbol (J). The sound members 101 to 104 are each one of the sectors! until ! V (F i g.!) Assigned, whereby that Schaltglicd is closed whose assigned sector is to be selected as .Sperrsektor. In the case of I ⁷ i g. 1 and 3 illustrated example, the selected .Sperrsektor II associated sound member 102 is closed, while all other .Schaltglieder 101, 103 and 104 are open. This means that the transmission path 62 selected by closing the associated switching element 102 has a different coupling status than the remaining transmission paths 61, 63 and 64 , 63 and 64 connected inputs of the NAND element 82 is always the L signal generated by the associated DC voltage source, while at the input of the NAND element 82 connected to the selected transmission path 62, an L signal or a 0 signal is applied, depending depending on whether the output 52 connected to the selected transmission path 62 has an L or a 0 signal. This is because the output 52 carries an L signal. thus an L signal is present at the input of the NAND element 82 coupled to the transmission path 62, whereas a 0 signal is present at this input when the output 52 carries a 0 signal. In the first-mentioned case, in which the input of the NAND element 82 coupled to the selected transmission path 62 carries an L signal, the coincidence condition is fulfilled at the inputs of the NAND element 82, so that it passes through and at its negated output a 0- Signal generated. If, on the other hand, the input of the NAND element 82 connected to the selected transmission path 62 carries a 0 signal in accordance with the last-mentioned case. so the coincidence condition is not met at the inputs of the NAND gate 82, so that this blocks and generates an L signal at its negated output.

In Fig. 3, two different combinations of binary signals at the outputs 51 to 54 of the coincidence elements are illustrated, namely the combinations LLLO (= sector IV; FIG. 1) and the binary combination LOLL (= sector IL FIG. 1). As can be seen, there is only an L signal at the output 81 of the logic device 8 if the binary combination LOLL ie. the characteristic binary combination of the sector II assigned to the closed switching element 102 is present at the outputs 51 to 54 of the coincidence elements V 12 to V'45. For all other binary combinations assigned to the unselected sectors. z. B. LLLO. there is a 0 signal at the output 81 of the logic device 8. This means that when the weapon is within the firing angle range but outside the selected blocking sector (this case is illustrated in FIG. 1), there is a 0 signal at the output 81 of the logic device 8, which enables the firing control. If, on the other hand, the position of the weapon falls into the selected locking sector, an L signal is present at output 81 of logic device 8. which blocks the shot.

The logic device 7 provided in the device according to FIG. 2 serves to block the weapon movement in both the azimuth and elevation directions. as soon as the weapon has reached the end of the range in question. The firing angle range in the direction of aciniutation is illustrated in FIG. 1 and in the illustrated example case, viewed in a clockwise direction, lies between 5600 and 800. The shot angle range in the elevation direction is illustrated in FIG. 4 and in the illustrated example lies between 0 and 800. FIG. 4 also shows the current armament shown with a dash-dotted line. which with the value 0
going horizontal plane the elevation angle ι / includes. Finally, in FIG. 4 shows the current direction of rotation of the weapon with a small arrow.

As already mentioned above, the logic device 7 receives the signals generated at the outputs 41 and 35 of the comparators Ki and KS together with three further signals D _x . D ₁₁ and 'i>' im: n supplied. The signal β represents the direction of rotation of the weapon in the azimuth plane and is measured by means of a suitable measuring device 16 (FIG. 5). z. B. a tachometer generator measured. The signal D ₁₁ represents the direction of rotation of the weapon in the elevation plane and is measured by means of a measuring device 17. B. a tachometer generator measured. A clockwise azimuth and elcvation rotation of the weapon corresponds to the binary state "O" of the signal D _n and the binary state "L" of the signal D ^. whereas a counterclockwise azimuth and elevation rotation of the weapon corresponds to the binary state “L” of the signal D ₁ or the binary state “0” of the signal D. This assignment of the direction of rotation to the two binary signal states "0" and "L" is shown in FIG. 5 through

Corresponding symbols next to the measuring devices 16 and 17 are illustrated. The signal //> ■ // ",." Is generated by a comparator 9 (FIG. 5), the first input 91 of which is connected to a measuring device 18, /. B. a synchro / digital converter, for the continuous determination of the current elevation angle η of the weapon is connected. The second input 92 of the comparator 90 is connected to a selector 93, which can have the same structure in the selector 1 to 5 (FIG. 2) and which is used to set the maximum permissible elevation angle i / ",. _n , that is, the weft angle range in the elevation direction, is permitted. According to the in FIG. The example shown in FIG. 4 is set to the value 800- on the selector 93.

The logic device 7 has a first AND element 71, the first input of which is connected to the measuring device 17 and the second input of which is connected to the comparator 9. The output of the AND element 71 leads to a control device, not shown, for the elevation servomotor of the weapon. This "weapon motor control" responds to the binary output signals of the AND element 71 in such a way that an L signal at the output of the AND element 71 stops the elevation servo motor of the weapon. This case occurs when the edge of the elevation firing angle range is reached when the weapon is rotated counterclockwise in elevation> inn (Di) = L signal) and the comparator 9 is reached as a result of the condition η> ?;, ". ,, generates an L signal. In this and only in this case there are

two inputs of the AND gate 71 to two L signals, so that the AND gate 71 switches through and on its output also generates an L signal. Generated at all other signal states at its inputs the AND gate 71 an output-side O signal, which leaves the weapon motor control unaffected.

The logic device 7 has two further AND elements 72 and 73, which are coupled on the output side via an OR element 74 and lead to a control device for the azimuth servo motor of the weapon, which is identical to the turret motor control of an armored vehicle if the weapon is on rotatable turret of the armored vehicle is mounted. The first input of the AND element 72 is connected via an inverting element 75 to the output of the measuring device 16, to which the first input of the AND element 73 is also connected. The second input of the AND element 72 leads to the output 41 of the comparator K 1, while the second output of the AND element 73 leads to the output 35 of the comparator K 5. The "tower motor control" responds to the binary signals at the outputs of the AND gates 72, 73 in such a way that the motor is stopped in the event of an L signal. This is the case. when the weapon has reached either one or the other edge of the shooting angle range in the direction of the azimuth. ie. if one of the conditions n. * <ix 1 * or λ *> λ 5 * is met with a counterclockwise or clockwise rotation.
