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 certain sector of their field of fire is located. B. Residential Areas lie or operate their own combat troops, which are protected against unintentional fire should be. For this purpose, in the above-mentioned, known device according to DE-PS 17 28 222 measuring devices provided for the current azimuth and elevation position of the weapon, their output signals continuously with electronically stored angle values for the blocked area be compared. In the event of a match between the measured and stored angle values the shot is blocked by a blocking signal.

To store the angle values of the restricted area in the electronic memory, the Directional gunner a complete turn of the gun by 360 °, which corresponds to 6400 (line), and changed continuously the elevation angle according to the contours to be blocked. Such programming however, it is laborious, not very flexible and imprecise, so that safety margins are added to the stored restricted area need to be done.

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

The invention is explained in more detail with reference to the drawings. It shows

Fig. 3 is an electrical circuit diagram of one of the Establishment according to FIG. 2 provided first logic device;

F i g. 4 shows a schematic view of the firing angle range of a weapon in the plane of elevation and FIG

Fig. 5 is a circuit diagram of another in which Device according to Figure 2 provided logic device, partly in block diagram representation.

F i g. 1 shows a plan view in the azimuth plane of a weapon, for example a cannon. The weapon can be pivoted about a pivot point in azimuth and elevation, which is in the middle of a 6400 full circle Uhrzei- ^κ gersinn seen. Of course, it is also possible to choose the range of the weft angle as desired, for example 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 a restricted sector Instead of sector II, any other of the remaining sectors I, HI or IV can also be selected as a restricted 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, encloses the angle χ calculated in the clockwise direction. Furthermore, the weapon should rotate counterclockwise in the manner indicated by a small arrow. *O

A total of five voters 1 to 5 are available to choose the weft angle range and sectors I to IV provided, at each of which an angle value from 4800 to 1600 of the 6400 circle can be set. 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, the selector 1 is set to the value 5600-. the voter 2 on the Value 6000-, the choice 3 to the value 0-, the voter 4 to the value 400- and the voter 5 to the value so 800- discontinued. The opening angles of the individual sectors I to IV are in the example shown chosen the same size and amount to 400-. Of course, the opening angles of the individual sectors I to IV can also be chosen 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 is particularly easy to build Facilitates device according to the invention in digital form. In fact, as shown in FIG. 1 shows the Certain combinations of binary numbers can be assigned to individual sectors I to IV: Sector I die Binary combination OLLL, sector II the binary combination LOLL, the sector III the binary combination LLOL and sector IV the binary combination LLLO. Furthermore, the part (- "es 6400 - circle outside of the The weft angle range is assigned the binary combination LLLL

The device according to the invention illustrated in FIG. 2 has the already mentioned selectors 1 to 5, which can be set manually to a value of the 6400 circle. The set values can be read, for example, on a luminous digit display of each selector. Instead of a circle division into 6400, it is of course also possible to choose a 360 ° division, in which case the corresponding angle values are set in degrees on the selector 1 to 5. The angle values set by means of the selectors 1 to 5 are generally denoted by <% i to 5. B. a synchro / digital converter and fed in the form of an electrical signal to the inputs of the converters 11 to 15 The converters 11 to 15 are connected on the output side with the first input 'ines associated comparator K 1 to K 5, in a similar way are the voters 1 to 5 are connected to the second input of the associated comparator K 1, K 2, K 3, K 4 or KS via a respective downstream converter 21, 22, 23, 24 or 25. The converters 11 to 15 and 21 to 23 are identical in structure and transform the zugelführten angle signals "or" 1 to α 5 in signals of the respective KompIementärwinkeL Under a complementary angle, an angle ac * understood that with respect to a (on the circumference of an angular circle Fig . 1) lying angle «is mirror symmetrical to the center of this angular circle. The further complementary angle signals λ 2 * to «5 * at the outputs of the transducers 22 to 25 can be seen from FIG. 1 using the intersection points between the 6400 circle and the dashed straight line through the pivot point. The transformation of the angle signals and λ 1 to λ 5 into the associated complementary angle signals <x * urrj o: 1 * to 5 * by means of the converters 11 to 15 and 21 to 25 has the purpose of producing the ambiguous value 0- = 6400- in to avoid the weft angle range and thus to create unambiguous conditions in the evaluation of the angle signals <x dnd λ 1 to λ 5 aei the device according to the invention.

Each comparator K 1 to K 5 has two outputs, of which the first output carries an L signal if the complementary angle «* at the first input of the relevant comparator is greater than the complementary angle λ 1 *, * 2 ·,« 3 *, « 4 * or <x 5 * at the second input of the relevant comparator. Conversely, the second output of each comparator K 1 to K 5 carries an L signal if the complementary angle at the first input of the relevant comparator is smaller than the complementary angle 1 ’, 2’, 3 *. λ 4 * or α 5 * at the second input of the relevant comparator. In the example shown in FIG. I has an L signal at the harvest output 31 of the comparator K 1 and an 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 K 3 there is an L or 0 signal, at the outputs 34 and 44 of the comparator ti 4 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 comparators K 1 and K 5 are coincidence elements, for example NAND elements, K12, V23, V34 and

V 45 connected downstream in such a way that in each case the first and the second output of adjacent comparators are connected in increasing order to the inputs of a common coincidence element. In the example shown, the coincidence element V 12 is connected to the outputs 31 and 42 of the comparators K I and K 2 , while the coincidence element V23 with the outputs 32 and 43 of the comparators K 2 and K 3, the coincidence element V 34 with the outputs 33 and 44 of the comparators K 3 and K 4 and the coincidence element V45 is connected to the outputs 34 and 45 of the comparators K 4 and ^ 5. The outputs 41 and 35 of the comparators K 1 and K 5, which do not lead to a coincidence element, lead to a logic device 7, which is explained in more detail with reference to FIGS. The outputs 51 to 54 of the coincidence elements V 12, V 23, K34 and V45 lead to a logic arrangement S, 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, for. 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 illustrated by way of example, it being understood that, instead of the chosen structure, other training options exist for the logic device 8. The logic device 8 has in the illustrated For example, there are a total of four transmission paths 61 to 64, each to one of the assigned outputs 51 to 54 of the coincidence members K12. V 23. V 34 resp.

V 45 are connected. Each transmission path 61 to 64 is via a z. B. manually operable shah member 101, 102,103 and 104, respectively coupled to an input of a NAND gate 82, the negated output to the output Sl of Lcgikeinrichtung 8 forms Each input of the NAND gate 82 is further connected via a series resistor R _y with a by Shah symbol © illustrated positive DC voltage source connected. The switching elements 101 to 104 are each assigned to one of the sectors I to IV (FIG. 1), the switching element being closed whose assigned sector is to be selected as the blocking sector. In the case of FIG. In the example illustrated in FIGS. 1 and 3, the switching element 102 assigned to the selected blocking sector II is closed, while all the other switching elements 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 state than the remaining transmission paths 61, 63 and 64. These different coupling states of the transmission paths 61 to 64 have the consequence that the transmission paths 61, 63 and 64 connected inputs of the NAND gate 82 always the L signal generated by the assigned DC voltage source! is applied, while an L signal or a 0 signal is applied to the input of the NAND element 82 connected to the selected transmission path 62, depending on whether it has an L or a 0 signal connected to the output 52 connected to the selected transmission path 62 . If the output 52 carries an L signal, 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 which the input of the NAND element 82 coupled to the selected transmission path 62 carries an L signal, the coincidence condition is met at the inputs of the NAND element 82, so that it switches through and generates a 0 signal at its negated output. If, however, according to the last-mentioned case, the input of the NAND element 82 connected to the selected transmission path 62 carries a 0 signal, the coincidence condition at the inputs of the NAND element 82 is not met, so that it blocks and an L at its negated output Signal generated.

In Fig. 3 illustrates two different combinations of binary signals at the outputs 51 to 54 of the coincidence elements, namely the combinations LLLO (= sector IV; FIG. 1) and the binary combination LOLL (= sector II; FIG. 1). As can be seen, there is an L signal at the output 81 of the logic device 8 only if, with the switching element 102 closed, the binary combination LOLL, that is, the characteristic binaries of the sector II assigned to a sector II at the outputs 51 to 54 of the coincidence elements V. 12 to K 45 is pending. For all other binary combinations assigned to the unselected sectors, e.g. 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 blocking sector, an L signal is present at the output 8i of the logic device 8 which blocks the firing of the shot.

The logic device 7 provided in the device according to FIG. 2 serves to block the movement of the weapon both in azimuth and in elevation as soon as the weapon reaches the end of the relevant Has reached the shot angle range. The shot angle range in the azimuth direction in FIG. 1 illustrates and is in the illustrated example case - clockwise seen - between 5600- and 800-. The weft angle range in the elevation direction is shown in FIG. 4th illustrated and is in the illustrated example case between 0- and 800-. 4 also shows the with dash-dotted line drawn current weapon position, which with the through the value 0-going horizontal plane includes the elevation angle η the current direction of rotation of the weapon is illustrated by a small arrow

The logic means 7 are, as already mentioned above, the signals generated at the outputs 41 and 35 of the comparators Kt or KS together with three other signals _ΰ Λ, _n D and JJ> T} max supplied with the signal D "represents the direction of rotation of Weapon in the azimuth plane and is by means of a suitable measuring device 16 (Figure 5), for. B. a tachometer generator measured. The signal D _n represents the direction of rotation of the weapon in the elevation plane and is measured by means of a measuring device 17, e.g. B. a tachometer generator measured. A clockwise azimuth and elevation rotation of the weapon corresponds to the binary state "0" of the signal D, or the binary state "L" of the signal D _x , whereas an azimuth and elevation rotation of the weapon in a counterclockwise direction corresponds to the binary state "La" of the signal D _n or corresponds to the binary state “0” of the signal D _x . This assignment of the direction of rotation to the two binary signal states “0” and “L” is shown in FIG. 5 through

16 and 17 illustrated. The signal η> r \ _m , _x is generated by a comparator 9 (FIG. 5), the first input 91 of which is connected to a measuring device 18, e.g. 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 the setting of the maximum permissible elevation angle ηπ ,, χ, d. h “of the weft angle range in the elevation direction. According to the example shown in FIG. 4, the value 800 is set 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 ts and the second input to the comparator 9 ucsscii. 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 (Di) = L signal) and the comparator 9 generates an L signal as a result of the condition η> _{7j m} “being fulfilled. In this and only in this case there are two inputs of the AND gate 71 two L signals on, so that the AND gate 71 switches through and also generates an L signal at its output. At all other signal states at its inputs, the AND gate 71 generates a 0 signal on the output side, which leaves the weapon motor control unaffected.

The logic device 7 has two more AND gates 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 mounted on the rotating turret of the armored vehicle. 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 KS . 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 case occurs when the weapon has reached either one or the other edge of the firing angle range in the azimuth direction, that is, when one of the conditions «* < ot, 1 * or a *> « 5 * when rotating counterclockwise or . clockwise is fulfilled.
