When performing the start-up test mode (POST) based on the requirements to minimize the availability time and high reliability of the modules used in the system, the concept of minimizing the test volume is implemented. Therefore, in peripheral devices 2, a conclusion about their serviceability is formed based on the results of POST, and the rest of the equipment is not checked. In the central device 1, in addition to POST, only communication lines with peripheral devices are checked. Starting tests generate data on the results of control and aetivize the phaphic environment. At the end of the start-up tests, control is transferred to the main control program.

Checking the health of on-board equipment includes monitoring the health of the docking nodes and the integrity of the power circuits of the on-board equipment. In accordance with the test program, a sequence of control commands is generated, which are transmitted through the CVC adapter 38 and the corresponding elements of the block 42 of galvanic isolation devices to the control inputs of the corresponding switches of the block 57 of switching insulation resistance control circuits, through which the serial input connection to the insulation resistance meter 53 of the corresponding input circuits . At the same time, the integrity of the signal and power supply circuits of the on-board equipment is checked, the connection of the connector of the docking unit and the presence of water in the transport-launch cup are controlled. With a positive result of the control of the corresponding circuits and control points at the output of the insulation resistance meter 53, information signals are generated that enter the calculator module 32, and from it through the corresponding network adapter 35 (36) through the main line 3 (4) of the local computer network in the computer 6 of the central device 1.

Using the meter 55, the voltage on the ampoule battery is monitored, from which, after the start of the facility, on-board devices are powered.

At the end of the above routine checks, the system switches to the pre-launch preparation of control objects, during which the central device 1 provides the organization of interaction with external systems 1. Information exchange with peripheral devices 2 is carried out using the main or backup lines 3, 4 of the local computer network and the redundant line 5 multiplex channel.

From the ship's navigation complex through a digital optically isolated serial channel through the converter 30 and the interface board 29, the central device 1 receives data on geographical coordinates, heading, pitching, speed of angular qualities and components of instantaneous and absolute speed. The same data is transmitted to the designated control object via the multiplex channel adapter 28 on the redundant highway 5 of the multiplex information exchange channel with peripheral devices and then passes through the multiplex channel adapter 37 to the corresponding calculator module 32, from which it is transmitted to the control object via the adapter 39.

A command to permit launch is received from the system for joint use of weapons via a relay communication channel through a second input-output of adapter 24 of the CVC and the information signals about starting operations are transmitted to the system.

During pre-launch preparation, an active window appears on computer monitor 9, which displays: astronomical time and date, data from the navigation system, information about the number of operational, assigned, remaining, canceled and exited control objects, a table of goal forms (without data ), as well as a button for selecting the target designation input option (automatic or manual), an indication button, when pressed, an active window appears with information on the prelaunch progress, a document power button nti, exit button, a set of buttons with which the stages of the system are set, buttons for assigning control objects, canceling control objects and canceling goals, unlock button, etc., manually controlled by the operator.

When choosing the automatic input of target designation data, the table of target forms is filled with data obtained from the ship's target designation system. In addition, the necessary data can be additionally entered by the operator manually through the operator entry active window. When manually entering target designation data, all data is entered by the operator.

When solving the task of target distribution, after the operator presses the corresponding button on the monitor screen 9, a graphic image of the target reach zones appears, and the goal form is supplemented by the results of solving the target distribution in the form of messages about the selected probability of hitting targets, the assigned number of control objects and the numbers of assigned control objects.

The necessary information is entered into the assigned control objects on the main or backup lines 3, 4 of the local computer network and then through the module 39 of information exchange with the control object of the corresponding

module 32 of the calculator. If it is not possible to start due to restrictions on pitching, range, angle of the post-start turn, etc., the restrictions can be removed by pressing the lock release button.

At any stage of prelaunch preparation, cancellation of assigned control objects and / or assigned goals can also be performed. When canceling assigned objects of poisoning by pressing the corresponding button on the monitor screen, the operator opens a window in which a set of buttons with the numbers of control objects appears, and by pressing the necessary buttons, cancels, while the pressed buttons are painted in red. Similarly, by pressing the button for canceling goals, a window opens with buttons indicating the goals, and by pressing the corresponding buttons, the goals are canceled.

To completely cancel the start, which is possible at any stage of pre-launch preparation, the operator uses the Cancel button of the control panel 46.

In the event of malfunctions that lead to the automatic cancellation of the start-up of individual control objects, a message is displayed on the monitor screen about the released and canceled objects indicating the reasons that led to the cancellation.

At the end of the prelaunch phase, the message End of software appears on the monitor screen. The system is ready for launching of the designated control objects, which is carried out upon obtaining permission to launch from the joint weapons system. Start is carried out by pressing the “Start” button on the control panel 46. In this case, the corresponding control signal is generated, which is transmitted via the main line 3 (4) of the local computer network to the calculator module 32 serving the designated object, and transmitted through the CVC adapter 38 to the control input of the contactor of block 48, which ensures the closure of the power supply circuit of bus 52 to which it is connected the power bus of the power supply module 45 of the start circuits, and from the module 45, the supply voltage is supplied to the actuator for starting the control object.

After the start of the start-up, the message End of start-up appears on the monitor, information about the number of serviceable, assigned, remaining, canceled control objects and a button for controlling the documentation device.

- 15 Emergency ejection of control objects is carried out by manually entering control glasses from emergency control panels installed on central device 1 or peripheral devices 2. In this case, the power supply circuit of the actuator for starting the launch is directly closed.

Thus, the proposed KASU DAC has wide functional capabilities, increased operational reliability and fault tolerance due to the introduction of an additional multiplex communication channel for central and peripheral devices, redundancy of communication channels with a target designation system, as well as the introduction of additional calculator modules in peripheral devices providing more reliable functioning of the channels information exchange with management objects.

The system also allows you to increase functionality by connecting additional computers and additional adapters.

The presented drawings and description allow, using the existing element base, to manufacture the system in an industrial way and use it to collect information, solve combat missions and generate control signals for launching the serviced control facilities.
