Description

 The invention relates to the field of automation and computer technology and is intended to control a complex of torpedo-missile weapons (TRV), including torpedo tubes (TA) and launchers of self-defense (PU SO), as well as control weapons of all types (torpedoes, missiles and self-defense )

 Automated control systems (ACS) are known for submarine torpedo-missile weapon systems, consisting of a number of autonomous systems, the devices of each of which solve only separate functionally delimited tasks. The tasks of controlling torpedo tubes, including their reloading, are assigned to the control panel and devices of the automated torpedo tubes control system (SAU TA) (Militori Technology, 1993, v. 17, 7), self-defense launchers for control system devices, missile prelaunch preparation tasks on prelaunch equipment (APP) (The Naval Archieci, 1193, ll. Gane ^ s Navy International, 1997, v. 102, 5). The tasks of prelaunch preparation of torpedoes and self-defense equipment and the tasks of generating and entering shooting data into weapons of all types, including missiles, are assigned to control panels and devices of the combat information control system (CIUS). Moreover, these systems provide weapon control of a specific set of their types, number and type of torpedo tubes and launchers.

 It is also known that each of these systems is built on devices that implement certain functions and fragments of the tasks of managing objects of a specific functional purpose and are designed for a specific number and type of SLTs and launchers, the number and type of samples of weapons and weapons of a certain purpose.

 All known control systems for submarine expansion systems are built on the above local systems, which, as a rule, have a heterogeneous hardware and software platform.

As a consequence, the disadvantage of such systems is the need for prelaunch preparation and data entry into weapons, as well as preparation of TA (launchers) and firing from devices having various circuitry solutions, which predetermines the following disadvantages of such systems:
- an increase in the composition of the equipment and, as a consequence, an increase in overall dimensions, power consumption (heat dissipation) and the number of cable ties;
- decrease in reliability due to an increase in the number of equipment and switching connections;
- an increase in spare parts.

 And as a consequence of these shortcomings - an increase in operating costs.

 The disadvantages of such systems should also include significant time and material costs when carrying out work on replacing samples of weapons used on submarines with new ones due to the fact that the modernization potential of these systems is provided, as a rule, at the instrument level, by the refinement (replacement) of equipment and instruments with the increase in equipment and software development.

 In addition to the noted drawbacks, the indicated systems have a common drawback, namely, that to ensure hardware-software communications with the side of the weapon located in the TA, the connection of the AMS, the power supply of the side of the weapon and the connection of the remote control for entering firing data is performed using special switching equipment, which leads to reduce the reliability of the functioning of the arms control paths.

 The closest technical solution adopted for the prototype is an automated control system for the TRV functional complex (Gane ^ s Navy International, 1997, v. 102, 5), containing control panels, prelaunch equipment, computing devices for generating target designation and shooting data, a connection device interface of the corresponding weapon located in the TA.

 The aim of the present invention is to reduce the hardware composition, reducing power consumption, heat, timing and cost characteristics of the design, as well as the manufacture and conduct during the operation of modernization work.

 To achieve this technical result, in a system built on three levels of control, unified devices of the second (CPCU) and third (PKU) levels are connected to the control panel of the CIUS. Devices of all levels are connected by segments of the local area network (LAN), for example, according to the MIL STD 1553 standard. The top-level device of the BIUS console is connected via LAN to the second-level device of the CPCU, which in turn is connected to sensors (D), signaling devices (C) and executive mechanisms (MI) of the common part of torpedo tubes (launchers), and is also connected by the LAN segment to the third-level control devices of the control panel. Moreover, each PKU device is associated with sensors, signaling devices and actuators of the individual part of a particular torpedo tube, as well as with weapons located in this TA for controlling prelaunch preparation and entering firing data into the weapon.

 Similarly, the tasks of controlling launchers (launchers) of self-defense means and the means of self-defense themselves are solved.

 The significance of the differences in the proposed technical solution lies in the construction of an automated control system for the TRV and CO complex on the basis of one system consisting of a single control panel and two standard unified devices providing joint control of weapons (torpedoes, missiles, self-defense equipment) and weapons (torpedo tubes, launchers settings). Moreover, the construction of these devices does not depend on the types of weapons used and means of self-defense.

 The number of unified TsPKU devices is determined by the number of types of weapon systems (TA, PU) of the submarine.

 The number of unified PKU devices does not depend on the types of weapons and means of self-defense and is determined only by the number of torpedo tubes (launchers) of the submarine.

 Such a solution implements independent channel control of each torpedo launcher (launcher) and weapons located in it, which excludes the possibility of group failure during multiple launch.

 The proposed technical solution provides the possibility of replacing the type of weapon (armament) during the modernization of submarines and the introduction of new types of weapons (means of self-defense) on submarines without replacing or installing additional devices as part of the system (while maintaining the number of SLT, PU). The solution to this problem is provided only by changing the software of the corresponding devices (remote control, CPU and PCU) and replacing them with individual modules from the unified series, discussed below, related to the specifics of the newly used weapons (weapons).

 The combination of devices of all levels with LAN segments reduces the number of cable connections, ensures the speed of information transfer, does not require an increase in the number of devices (CPKU and PKU) and the laying of additional trunk and local cables when upgrading weapons and weapons while maintaining the number of SLT and PU SO.

 This technical solution meets the criterion of the significance of differences, since the proposed set of distinctive features does not occur among the considered analogues and ensures the achievement of the goal of the invention.

 An enlarged structural diagram of the proposed automated control system for the TA complex of the expansion valve and submarine submarines is shown in Fig. 1.

On the structural diagram of figure 1 shows the control panel (PU) BIUS at the upper level and covered by the LAN CPCU at the second level and at the third level PKU devices, the number of which corresponds to the number of TA (launchers) of the submarine. The devices of adjacent levels are connected by segments of an optionally homogeneous local area network (for example, Ethernet on the upper level and MIL STD on the lower level), that is, from the perspective of exchanging information arrays, commands, and control and control signals, the system is based on a network association. All devices (CPKU and PKU) are built on unified circuitry and software solutions and include (figure 2):
1. The processor board (1), which has access to the instrument system bus (2), for example, VME bus.

2. The input-output module (3), having on one input the controller of the system bus of the device (4), and on the other - lines of the parallel interface. The module can be of three types and provide:
- the issuance of relay signals for controlling the executive mechanisms of the IF and OCH torpedo tubes (launchers) and on-board weapon equipment (self-defense equipment);
- reception of relay signals from sensors and signaling devices of IF and OCH of torpedo tubes (launchers) at all stages of preparation and production of a shot, as well as from on-board weapon equipment (self-defense means);
- issuing and receiving relay signals for control and monitoring mainly by means of self-defense and their launchers.

 3. Modules for receiving and processing analog signals (5), which, on the one input side, like all other modules, have a system bus controller (4), and on the other input side, an analog-to-digital converter with a switch at the input for receiving unified voltage signals and current from on-board weapon systems, as well as from sensors of the individual and common parts of TA (PU), for example, 0-4 MA, 4-20 MA, 0-10 V DC, etc.

 4. Digital signal receiving modules, which are one of the module types (3), which have a system bus controller (4) on the one input side and a corresponding interface controller for the subscriber on the other input side, for example, RS-485.

 5. Modules for organizing inter-instrument exchange by LAN segments (6), selected during the construction of the entire system, having on the one input side an instrument bus system controller (4), and on the other input side, a LAN controller, for example, MIL STD 1553 or Ehtemet controller.

 6. Modules (7) working on a special interface for torpedo, missile, and self-defense equipment, such as Airing, for exchanging code information with the weapon board during prelaunch and missile launch. The modules have a system bus controller (4) on the one input side, and a controller supporting the corresponding interface with the weapon board on the other input side.

 All modules are installed in the crate (dashboard) and communicate with each other through the dash system bus (2) laid in the crate.

 The system blocks arranged in this way (the racks with the modules installed in them in the quantity and set corresponding to the functional purpose of the unified device) are built into devices of all levels. All devices are equipped with built-in power supplies (8) that power all the modules of the system units through the system buses (2).

 The control panel uses the same system unit and, in addition, contains a standard set of PC hardware tools (monitor, keyboard, etc.). Weapons and weapons are controlled by the operator from this console.

 The CPCU device, which performs a number of important system functions to increase the reliability of the system as a whole, is made according to a three-processor scheme. The processors are synchronized at the program level with the processing of information according to the majority of the two out of three voting schemes for input and output.

The CPCU device provides:
- management and control of the operation of all PKU devices;
- reliability control of all transmitted information;
- management of groups of mechanisms of the common part of torpedo tubes (launchers);
- control of power supply devices of the system.

 Diagnostics of failures and malfunctions in the weapon and weapon control channels are also entrusted to CPCU devices.

 PKU devices, the number of which, as noted above, is equal to the number of TA (PU), provide control and management of the individual part of each TA (PU), pre-launch training, as well as data entry into weapons and means of warfare located in the TA (PU).

 The reliability of PKU devices is ensured by circuit solutions of their modular construction.

 This structure of the system construction provides the required reliability and reliability of data generation and bringing them to the control objects, as well as reliable control of these objects.

 The combination in one channel (in the PKU device) of the control functions for prelaunch preparation and input of firing data into weapons, as well as the preparation of a torpedo tube (including its reloading) for firing, allows you to abandon a number of separate systems and devices (APP, SAU TA, etc.), to provide increased reliability of the control system of the TRV and SB submarine complex as a whole.

 The presence of network modules (6), providing the exchange of all data, code messages with high speed and reliability, made it possible to abandon the numerous physical connections between the devices and form independent control channels for each SL (PU) and weapons placed in it (self-defense means), which in turn, reduces the number and weight of cable routes.

 Combining PKU devices with a set of replaceable modules with a total number of up to 15 provides the system as a whole with high modernization capabilities for introducing new weapons and upgrading the submarine’s expansion tank.

 The components of the system are under the control of a real-time operating system (Hard read time), for example QNX.4.2.X.

 Programs that implement algorithms for solving the problems of monitoring the measured parameters of controlling TA actuators (PU), generating firing data, transmitting commands and firing data to lower-level PKU devices are placed in an electrically reprogrammable memory, for example, a Flash disk installed on microcomputer boards of unified system devices.

 Each program that provides the implementation of algorithms for preparing a torpedo tube for firing various types of weapons has its own number.

 When a command is received via LAN from the CPCU to prepare a torpedo tube for firing a weapon from this unit, the necessary algorithm for preparing the TA for the firing and the pre-launch preparation program for the desired type of weapon at the appropriate number are selected in the PKU memory. From this moment on, two independent control processes take place in the system - the process of controlling a torpedo tube and the control process of weapons placed in it.

 From the control panel in TsPKU through three channels issued a command to prepare weapons. After majoring the team in the CPCU, as well as any other information received and transmitted, the team is transmitted to the lower segment of the network and accepted by the PKU, which carries out prelaunch preparation of the weapon. In parallel with the control of prelaunch preparation in PKU on the remote control, the task of generating firing data is solved, and after receiving from the PKU a signal about the weapon’s readiness from it through the same channel PU-TsPKU-PKU, the weapon receives an array of firing data, which in the special interface module (7) of the PKU It is converted to the format of the data entered into the weapon, and through the TA connector it enters the on-board equipment of the weapon.

 Another control process (running in parallel) - the process of controlling a torpedo tube in preparation for firing and producing a salvo - is under the control of two devices. The CPCU device controls the mechanisms of the general part of the torpedo tubes, the PKU device controls the mechanisms of the individual part of a specific torpedo tube according to the selected algorithm for its preparation. After the preparation for the shot is completed and the control panel receives a signal from the CPCU about the readiness of the TA, a shot command is issued from it via the LAN. With such a functioning of the weapon control channels (weapons of mass destruction), which ensures its combat use with high reliability, the system implements salvo firing of ammunition in any combination of torpedo tubes assembled into a salvo, independent preparation of weapons and torpedo tubes (launchers).
