Description

 The invention relates to defense equipment, in particular to defense or offensive systems with the installation of smoke screens, and can be used in systems for setting aerosol curtains from the side of a moving object.

 Currently, much attention is paid to the development and improvement of optical-electronic countermeasures designed to create optical interference to systems using laser rangefinders and target indicators for their work.

 A known system for launching smoke cartridges, designed for individual and group protection of tanks by remote placement of a smoke screen, containing launchers, control panel, smoke cartridges. The system is electrically activated by command from a control panel located inside the fighting compartment.

 A disadvantage of the known system is the lack of automatic detection and control of the installation of a smoke screen, which leads to an increase in the likelihood of defeat by the enemy.

 Closest to the technical nature of the device is a control device for an active protection complex, containing an information processing unit and a direction for firing with N inputs, connected to a grenade launch unit. At the same time, the inputs of the information processing unit and the shooting direction are intended for receiving information from electron-optical sensors.

 The disadvantages of this device include the low reliability of determining the direction to the source of laser radiation, the lack of control of the charge of grenade launchers, which reduces the efficiency and reliability of optical interference and increases the likelihood of damage to objects by the enemy.

 The purpose of the invention is improving the efficiency and reliability of the supply of interference.

 This is achieved by the fact that in the control device of the optical jamming supply system, which contains an information processing and shooting direction unit connected to the grenade launcher, the M outputs of which are the first outputs of the control device, a power selector is added, N inputs of which are the inputs of the device, and the output of the power selector is connected to the first input of the information processing unit and setting the firing direction, a control signal driver and a grenade launcher charge control circuit. The input of the control signal generator is connected to the second output of the information processing unit and the firing direction, and its N outputs are the second outputs of the device. The M inputs of the grenade launcher charge monitoring circuit are connected to the corresponding outputs of the grenade launcher, and the control input and output are connected respectively to the third output and second input of the information processing unit and the shooting direction.

 The introduction of a power selector increases the reliability of determining the direction to the laser source due to the separation of the main signal (the most powerful) in the presence of common-mode interference on other electron-optical sensors in duration.

 The introduction of a control signal generator also increases the reliability of determining the direction to the laser radiation source by providing control of the communication line.

 The introduction of a grenade launcher charge control scheme provides a choice of a charged grenade launcher that effectively protects the direction of attack.

 In FIG. 1 is a structural diagram of a device for controlling an optical interference supply system; in FIG. 2 diagram of the algorithm of the information processing unit and setting the direction of fire.

 The control device of the optical jamming system contains (see Fig. 1), an information processing unit and a firing direction setting unit 1 connected to a grenade launch unit, the 2 M outputs of which are the first outputs of the device.

 In addition, the device further comprises a power selector 3, N inputs of which are the inputs of the device, and the output of the selector 3 is connected to the first input of block 1, the driver of the control signals 4, N outputs of which are the second outputs of the device, and the output is connected to the second output of the block 1, a charge control circuit for grenade launchers 5, the M inputs of which are connected to the corresponding outputs of block 2, and the control input and output are connected respectively to the third output and second input of block 1. In addition, the device contains spruce buzzer 6 and the operator panel 7 with light display connected respectively to the fourth and fifth outputs of the power unit 1. The input selector 3, and outputs the control signal generator 4 are connected respectively to the outputs and inputs of electro-optical sensors 8.1 8.N.

 The grenade launcher 2 with its outputs is connected to the corresponding grenade launchers 9.1 9.M.

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

 After switching on, the control device performs (see Fig. 2) control of the communication line between the control device and the electron-optical sensors 8.1 8.N.

 Monitoring the communication line is as follows.

 The control signal generator 4 under the control of block 1 is sequentially for each sensor 8.1 8.N generates a control pulse at each of the second outputs of the device. The response pulses from the monitored sensor through the communication line are received through a power selector 3 in block 1 for processing. In block 1, the determination of serviceable and faulty bits of the communication line. Faulty are those discharges for which no response pulse was received. Information about the state of the communication line with the 8.1 8.1 sensors. N is stored in block 1 and is used for further work.

 The power selector 3 selects the maximum signal duration from the set of signals received at the input of the control device from the 8.1 8.1N sensors at the time they receive laser radiation.

Block 1 periodically reads the status of the power selector 3 and monitors the appearance of the most powerful signal. After its detection, the shaper 6 under the control of unit 1 issues an alert signal to the intercom within a predetermined time. Then block 1 reads the code information from the output of the power selector 3, corresponding to the most powerful signal, and determines the direction to the laser radiation source based on the results of monitoring the communication line:
roughly with partial damage to the communication line between the sensor, from which the most powerful signal and the control device came from;
exactly with a working communication line.

 After determining the direction to the source of laser radiation, block 1 generates a signal at the fifth output, which provides information on the light panel of the console 7 about the direction to the source of laser radiation.

 After that, with a rough determination of the direction of the laser radiation source, the grenade launch unit 2 under the control of unit 1 generates signals that ensure the grenade is fired from all charged grenade launchers, protecting the zone corresponding to the sensor from which the most powerful signal was received.

 With an accurate definition, the charge control of grenade launchers 9.1 9.M. For this, the circuit 5 under the control of block 1 monitors the charge of the grenade launchers and transmits this information to the second input of block 1. Block 1, taking into account the direction to the radiation source and information about the charge of the grenade launchers, selects a grenade launcher that optimally protects this direction, for example, in the case of a main discharge grenade launcher is selected one of the closest to the left or right of it.

 After selecting a grenade launcher, the grenade launch unit 2 under the control of block 1 generates a signal at one of the M outputs of the control device, which ensures the operation of the selected grenade launcher.

 The considered principle of operation of the control device of the optical jamming system is illustrated by the flowchart of the information processing unit 1 and setting the firing direction in the jamming mode (see Fig. 2), which details the sequence of actions performed by block 1 and does not require additional explanations.
