Description

 The invention relates to weapons, in particular, to defense systems or offensives with the installation of smoke screens, and can be used in systems for placing aerosol curtains from a moving object, for example, a tank, and is intended to create optical interference to control systems of an anti-tank environment, using for their radiation from laser rangefinders and designators.

 The known control device of the optical jamming system contains a selector, power, the input of which is the first input of the control device of the jamming system, and the output is connected to the input of the information processing unit and setting the direction of fire, the output of which is connected to the input of the grenade launcher, the outputs of which are N outputs control devices of the jamming system.

 A disadvantage of the known device is the possibility of unauthorized firing of smoke grenades at an arbitrary point in time in case of failure of one or more channels of the grenade launcher.

 The aim of the invention is to increase the reliability of the control device of the optical jamming system by eliminating shots from smoke grenades in case of malfunctions in the channels of the grenade launcher.

 In FIG. 1 shows a block diagram of a device for controlling an optical jamming system.

 In FIG. 2 shows a functional block diagram of the information processing unit and setting the direction of fire.

 The control device of the optical jamming system contains a power selector 1, the input of which is the input of the optical jamming system control device, and the output is connected to the input of the information processing unit and setting the firing direction 2, grenade launcher 3, the outputs of which are the outputs of the control device, counter 4 the input of which is connected to the first output of the information processing unit 2, and the output with the first input of the comparison circuit 5, the second input of which is connected to the second output of the information processing unit setting the shooting direction 2. The output of the comparison circuit 5 is connected to the first input of the 2I-NOT 6 element, the second input of which is connected to the third output of the information processing unit and the shooting direction 2 and the first input of the switch 7, the second input of which is connected to the output of the 2I-NOT circuit 6. The output of the switch 7 is connected to the input launch grenades 3.

 The information processing unit and the direction of firing 2 are made on a modular basis and have a trunk communication structure between the blocks. The signals "Read memory", "Write to memory" "Output" represent the control line. The CPU module 8 comprises a central processing unit, a system controller, data buffers and addresses (not shown). The random access memory module 9, the read-only memory module 10, address decoders 11 and 12 are made on known standard microcircuits.

 The first output port 13, the second output port 14, counter 4, comparison circuit 5, logic element 2I-NOT 6 and the switch 7 are also made on the corresponding well-known standard microcircuits.

 The control device of the optical jamming system operates as follows.

 In the initial state, the counter 4 is in the zero state and, therefore, the code 0000 is also set at the first input of the comparison circuit 5, while at the first output of the information processing unit and the setting of the shooting direction 2 there is a logic zero level, and at the second output, code 1100, which arrives at the second input of the comparison circuit 5. Since the codes at the first and second inputs of the comparison circuit 5 are not equal, then its output sets the logic zero level, which goes to the first input of the logic element 2I-NOT 6 and, thereby, blocks signal passing from the second input of the 2I-NOT 6 element to the second input (permission input) of the switch 7, which, in turn, blocks the operation of the grenade launch unit 3.

 Upon detection by the equipment of information collection of a signal about the beginning of an enemy attack, it generates a “CODE” signal, which is fed to the input of the control device of the optical jamming system.

 After preliminary processing in the power selector 1, this signal is fed to the input of the information processing unit and the shooting direction 2, which determines the direction of the enemy’s attack and begins to prepare smoke grenade launch circuits.

 The information processing unit and setting the direction of firing 2, in accordance with its algorithm of operation, sets the Q value in the binary code at the second output, which is fed to the second input of the comparison circuit 5. Next, this same block 2 forms a sequence of Q clock pulses at the first output, which go to the counting input of the counter 4 and lead to a change in its output state. At the moment of the arrival of the Qth pulse, the value of the binary code equal to Q is set at the output of counter 4. This code is fed to the first input of the comparison circuit 5, as a result of which the level of the logical unit (i.e., the enable signal) appears at its output at the first input of element 2 AND NOT 6.

 After that, the information processing unit and the shooting direction setting 2 sets the code value of the required channel of the switch 7 on the third output, which is fed to the first input of the switch 7 and to the second input of the 2N-NOT 6 element. As a result, the code of the desired channel is set on the first input of the switch 7, and at the second input, a signal allowing its operation, which leads to the formation of a signal on the selected channel of the grenade launcher 3.

 After the end of the signal generation time, the information processing unit and the shooting direction setting 2 generates a signal to reset the counter 4 to zero at the first output, and also sets the signal levels at output 2 and 3 corresponding to the initial state.

 Thus, the formation of a signal to launch smoke grenades is carried out only if the processing unit performs information and sets the firing direction 2 of a special sequence of commands (i.e., checks the correct operation), which significantly reduces the likelihood of unauthorized generation of signals to launch smoke grenades and leads to an increase the reliability of the entire device. In the event of a malfunction of the information processing unit and setting the shooting direction 2, a signal is not generated at the output of the comparison circuit 5.
