Description

The invention relates to the field of information and telecommunication technologies and can be used in control systems of power structures, in control systems used in the event of accidents and emergencies.

Automated control systems used to solve problems in emergencies, in emergency situations and for military purposes have fixed and mobile components (subsystems), each of which has its own local area network (LAN). When creating such systems, special attention is paid to increasing their mobility, efficiency and speed. Their application has the following features:

- in the place of constant deployment information is prepared and constantly updated, which will be used by the mobile component in the performance of the task;

- upon receipt of a command to complete the task, information from the databases of the stationary component is copied to the database of the rolling component;

- due to the large amount of information transmitted at the same time and the small time allotted for this, it is impossible to use relatively low-speed standard means of data transfer with standard means of ensuring the security of information available for ensuring interaction between units and governing bodies;

- measures are envisaged to ensure the security of information, and different demands are made on the stationary and mobile components in this regard, and different sets of rules and algorithms for ensuring information security may apply;

- connecting the LAN of the mobile component directly to the LAN of the stationary component is impractical (and sometimes impossible) for the following reasons:

a) the administration of the integrated LAN is significantly complicated due to the dynamic change in the number of computers in the network and the mismatch in practical cases of the sets of protocols operating in both parts of the network;

b) such a connection may be impossible or expensive due to the incompatibility of the rules and algorithms for ensuring the security of information in the combined LAN;

- the hardware components of the movable component have improved characteristics compared to stationary in terms of weight and dimensions, power consumption and deployment speed.

A well-known set of automation tools is the command post of a tactical connection (PM of the Russian Federation No. 41889, G06F 15/16, 2004).

The device contains a set of data transmission tools for communication with external subscribers, with which the voice output line of the complex is also connected, a local computer network, interconnecting computers of workstations and display computers, a plotter, a projector (collective use display tool), and summary tools documentation, allows you to organize parallel work 26 automated workstations (AWS) and the exchange of information with 52 subscribers. This well-known complex can be represented either in a stationary or in a mobile version.

A disadvantage of the known complex is that it does not provide for the simultaneous operation of the stationary and mobile parts of the complex, the rapid updating of the databases of the mobile part and the solution to the problems of ensuring information security.

A known set of automation equipment for command and control for command and staff vehicles (PM RF №37838, G01S 13/00, 2003). The complex contains video surveillance blocks installed on the vehicle, measuring the distance to the object, determining the location of the vehicle, collecting data, receiving and transmitting data with information protection, and a control unit in the form of a computer with anti-vibration fasteners. The computer has a multitask Russified operating system and software that allows you to conduct documented information exchange of subscribers through communication channels with the simultaneous calculation of specialized tasks. This known device is designed to provide interaction between the individual units of the tactical forces. However, it does not provide for the possibility of connecting a stationary complex to the LAN for quick and safe updating of information in computers of a known complex.

Closest to the technical nature of the proposed system (the first option) is a movable set of control automation equipment according to US Pat. RF invention No. 2266563, G06F 17/60, 2005, adopted as a prototype.

An enlarged block diagram of the prototype device is presented in figure 1, where it is indicated: 1 - a movable complex of control automation; 2 - data transmission media; 3 - communication facilities; 4 ₁ -4 _n - workstations (AWS); 5 ₁ -5 _n - computers from the workstation; 6 - LAN, 7 - computer outputs for connecting to a LAN.

Data transmission facilities 2, communication facilities 3, AWS and computers in the aggregate comprise the technical facilities of the complex.

AWS 4 ₁ -4 _n contain the corresponding computers 5 ₁ -5 _n , which are connected through outputs 7 to LAN 6. Output 7 provides an electrical (or optical) interface and data exchange via LAN 6, for example, in accordance with the Ethernet standard. To the same LAN 6, communication means 3 and data transmission means 2 are connected.

The prototype device operates as follows. Officials who have access to the system and information in accordance with the access control program form documents, certificates, instructions, etc. on a computer 5 ₁ -5 _n that require transmission to subscribers, both at the control point and to external subscribers. For this, the official selects the necessary document from the database and fills in its details. Then he selects the subscriber table and, noting the desired destination, sends a document that is transmitted by means of data transfer 2 and then by communication means 3 after processing by cryptographic protection equipment (included in data transfer means 2). The incoming message from the communication means 3 after the cryptographic protection equipment has disclosed the data, after its assembly from the codograms and acknowledgment, is received in accordance with its address-service part and the details on the user's computer. In order to manage the rear and technical support bodies on a computer 5 ₁ -5 _n, the tasks of processing cartographic information, automated information exchange with higher and lower rear (technical) support bodies, and managing the lower rear (technical) support bodies both in automated and in manual modes. Communication means 3, in addition to data exchange, also provides telephone communication (open and closed) with higher and lower control points (PU), radio communication when moving in a convoy.

The disadvantages of the prototype device are limited functionality, determined by the lack of implementation of the stationary part of the complex, the low bandwidth of data channels for updating data in a computer of a mobile complex of control automation equipment before starting the task.

Thus, the aim of the invention is to expand the functionality of the system.

This is achieved by the fact that in the automated control system including the first subsystem, the technical means of which are connected by a local area network (LAN), according to the invention, a second subsystem is introduced containing similar technical means connected by a local area network, while in the LAN of the first subsystem one of the computers has an additional network output for communication with the corresponding computer from the LAN of the second subsystem, which has a similar additional network output, and for data exchange between the subsystems of the system A LAN is used, formed by connecting the mentioned outputs.

The scheme of the proposed device (first option) is presented in figure 2, where it is indicated: 1, 8 - the first and second (respectively, mobile and stationary) subsystems; 2 - data transmission equipment; 3 - communication facilities; 4 ₁ -4 _m , 4 ₁ -4 _n - AWP; 5 ₁ -5 _m , 5 ₁ -5 _n - computer; n, m - number of workstations in the mobile and stationary subsystems, 6 - LAN; 7 - computer output; 9 - additional network output of a dedicated computer; 5 _i and 5 _j - the first and second dedicated computers (as selected computers 5 _i and 5 _{j are} designated computers 5 _{1 of the} corresponding subsystem); 10 - the third LAN.

Data transmission facilities 2, communication facilities 3, AWS and computers in the aggregate comprise the technical facilities of the complex.

The proposed automated control system consists of two (first and second) subsystems: mobile 1 and stationary 8. Stationary subsystem 8 for the purpose of automated control contains technical means (possibly in a stationary version) of the same purpose as in mobile subsystem 1: data transmission equipment 2, communication equipment 3, AWP 4 ₁ -4 _m , which include 5 ₁ -5 _m computer. The computers from the workstation in each of the subsystems 1, 8 are connected to the corresponding LAN 6 through the output 7. In each of the subsystems, a computer (5 _i in the first subsystem) is selected, which has an additional network output 9 for communication with a dedicated computer 5 _j from the LAN 6 of the second subsystems. By connecting the outputs 9 of both dedicated computers 5 _i and 5 _j , a third LAN 10 is formed.

The formed third LAN has a simple structure with simple administration, and it uses the rules and algorithms that provide for secure data exchange between the stationary 8 and mobile 1 subsystems of the automated control system.

To improve the operational and weight and size characteristics of the mobile system, its technical means can be placed in compact packages, for example, in suitcases or containers.

The proposed automated control system operates as follows. Officials operating the stationary subsystem 8, in the course of daily activities, generate outgoing documents on the AWP computer and process incoming documents from higher and lower management bodies. The technical means of the stationary subsystem 8 during the work of officials function in the same way as in the prototype. In this case, information is generated in the databases of the stationary subsystem 8, which will be used during the operation of the mobile subsystem 1, for example, a prototype device. If it is necessary to organize the exchange of data between two subsystems 1 and 8 of the automated control system shown in Fig. 2, a LAN 10 is formed by connecting additional network outputs of the dedicated computers of both subsystems using a cable. This LAN 10 is used by an official operating the system to exchange data between subsystems using standard tools available in the system.

Existing automated control systems, as well as the proposed one, may contain more than one mobile subsystem. For example, in the tactical management system, complexes should be provided for controlling communications, artillery, aviation, etc. See, for example, Scheme 5. Organization of the US Infantry Division on p. 255 in the book Glazunov NK, Maslennikov P.E. Ground forces of the capitalist states. - 2nd ed., Revised. and add. - M .: Military Publishing House, 1980. - 416 p., Ill., Adopted as a prototype for the second version of the proposed control system.

An enlarged diagram of the prototype device (for the second option) is presented in Fig. 3, where it is indicated: 1 ₁ -1 _k - governing bodies and units from the division with the corresponding control systems. The division commander and division headquarters manage the subordinate units and management bodies. The management system of such a complex organizational unit as a division consists of several subsystems. Before the start of hostilities, units are assigned tasks. For example, to create the necessary grouping of artillery and its distribution, she is given typical tactical tasks. This creates the appropriate organizational structures for the battle.

The disadvantages of the prototype device are limited functionality, determined by the lack of implementation of tools for the rapid update of data in the computer subsystems before starting to perform the task.

To eliminate these shortcomings, an automated control system consisting of several subsystems, the technical means of which are connected by separate local area networks, is introduced according to the invention, and in the LAN of the first subsystem one of the computers has an additional network output for communication with the corresponding computers from the LAN of other subsystems, connected to the switch, to the outputs of which are connected additional network outputs of the corresponding computers of the remaining subsystems, and for data exchange between the subsystems a LAN is used, formed on the basis of a switch and a computer with additional network outputs.

Figure 4 presents a diagram of a second variant of the proposed control system, where it is indicated: 1 ₁ -1 _k - k subsystems; 5 ₁ -5 _k - selected computers; 9 - additional network output of a dedicated computer; 10 - the third LAN; 11 - switch. To simplify, figure 4 does not show the following blocks available in both the first and second versions: 2 - data transmission equipment; 3 - communication facilities; 4 ₁ -4 _m - AWP; 6 - LAN.

Data transmission facilities 2, communication facilities 3, AWS and computers in the aggregate comprise the technical facilities of the complex.

The second version of the proposed control system contains k subsystems 1 ₁ −1 _k , each of which contains technical means (possibly in stationary version): data transmission equipment 2, communication equipment 3, AWP 4 ₁ -4 _mj (not shown in FIG. 4) , which include computers 5 ₁ -5 _mj , mj is the number of workstations in the j-th subsystem. Computers from the workstation in each of the subsystems 1 are connected to the corresponding LAN 6 through output 7 (not shown in Fig. 4). In each of the subsystems, a computer is allocated (5 _i in the first subsystem, denoted as 5 ₁ ), which has an additional network output 9 for communication with dedicated computers 5 _j (denoted as 5 ₂ -5 _k in other subsystems, with j = 2, 3 , ... k) from the LAN 6 other subsystems. By connecting through the switch 11 the outputs 9 of the allocated computers 5 _i and the combination of the selected computers 5 _j , a third LAN 10 is formed. In this embodiment, the dedicated computers of the subsystems are connected to the switch 11 by the corresponding cables.

The proposed automated control system (second option) operates as follows.

Officials operating the subsystems 1 _j (j = 1 ... k), in the performance of their duties, operate the corresponding subsystems similarly to the first option. In LAN 10, formed by switch 11 and additional network outputs 9 of dedicated computers connected to it, the network protocol stack common to all selected computers is valid, as well as uniform rules and algorithms that provide for secure data exchange between subsystems of an automated control system. The exchange of data between subsystems in the presence of several subsystems in the system is organized by standard means available in the system, similarly to that described in the first embodiment.

To improve convenience and efficiency when working with an automated LAN control system between dedicated computers, the subsystems are based on the equipment of one of the wireless technology standards (see, for example, S. Gordeychik, Once again about WLAN, BYTE Russia, 2005, No. 8.

A device for a wireless network in an office is known, published in an article by V. Maksimov “The diverse application of wireless technologies”, PC Week / RE No. (484) 22'2005 of June 21, 2005, heading: NetWeek, p. 21, Fig. 2, adopted prototype for the third version of the proposed system.

The disadvantages of the prototype device are limited functionality, determined by the lack of implementation of tools for the rapid update of data in the computer subsystems before starting to perform the task.

To eliminate these shortcomings, in an automated control system consisting of several subsystems, the technical means of which are connected by separate local area networks, according to the invention, an access point and other radio facilities are introduced, which together ensure the functioning of a wireless LAN, and one of the computers in the LAN of the first subsystem has an additional network output for communication with the corresponding computers from the LAN of other subsystems, connected to the access point, and similar additional network outputs The corresponding computers from the LAN of other subsystems are connected to the radio, and this wireless LAN is used to exchange data between the subsystems.

An enlarged diagram of the proposed communication system (third option) is presented in figure 5, where it is indicated: 1-1 _k subsystems (k is the number of subsystems); 5 ₁ -5 _k - selected computers; 9 - additional network output; 10 - LAN; 12 - access point (node) that supports the standard of wireless technology; 13 ₁ -13 _k - radio stations operating according to the same wireless technology standard as the access point 12. To simplify, figure 5 does not show the following blocks available in the proposed system in the first, second, and also in the third embodiment: 2 - data transmission equipment; 3 - communication facilities; 4 ₁ -4 _mj - AWP; 5 ₁ -5 _mj - computers; mj is the number of workstations in the jth subsystem; 6 - LAN.

Data transmission facilities 2, communication facilities 3, AWS and computers in the aggregate comprise the technical facilities of the complex. The radio stations 13 and the access point 12 together constitute the radio.

The proposed control system (third option) provides simultaneous communication of one subsystem with several other subsystems using wireless technologies.

The first subsystem 1 ₁ through the additional network output 9 of the dedicated computer 5 _{1 is} connected to the access point 12, and the additional network outputs 9 of the dedicated computer 5 ₂ -5 _{k of the} other subsystems are connected to the corresponding radio stations 13 ₂ -13 _k working according to the same wireless technology standard as the access point 12. The joint operation of the access point 12 and the radio stations 13 ₁ -13 _k provides the construction of a local wireless network through which data is exchanged between the subsystems.

The proposed automated control system in the third embodiment operates as follows.

The officials of the subsystems in the performance of their duties operate the corresponding subsystems similarly to the first option. In LAN 10, formed by access point 12, radios 13 connected to additional network outputs of dedicated computers 9 and dedicated computers 5, the network protocol stack common for all dedicated computers 5 and common rules and algorithms provide for the secure exchange of data between subsystems of the automated control system . The exchange of data between subsystems using wireless technology is organized by standard means available in the system, similar to how it is done in the case of the first and second variants of the claimed control system.

Large automated control systems are built in stages and may contain subsystems that differ in hardware and software execution, according to the protocols operating in them, and also according to sets of rules and algorithms for ensuring information security. In this case, it may also be impossible to exchange data between the subsystems by simply connecting the LAN of one subsystem to the LAN of the other subsystem. The proposed device can also be used to ensure safe data exchange between the subsystems of a stationary automated control system, that is, when all subsystems are stationary.

The proposed technical solution is implemented using widely known and affordable products, has wider functionality, better tactical and technical characteristics.
