Description

The invention relates to control systems, and in particular to control systems of geographically dispersed objects, and can be used as hardware communication control in the field to control communication networks and systems for various purposes and to ensure the stable functioning of mobile objects of communication nodes and systems.

The communication center (CS), by its functional purpose, refers to the elements of a communication system designed to ensure the exchange of information to officials of management bodies using the means of transmitting (receiving) information available at their workplaces. The stability of control of mobile objects largely depends on the stable operation of communication devices in the information areas organized by the communication center.

The reliability of the functioning of communication networks is largely determined by the organization of their management system, which includes a command transmission network for managed objects and a network for collecting data on the state of technical means that provide for the creation of various communication channels designed to provide various types of communications, and also depends on the application required for this purpose terminal devices for transmitting and receiving information on the management of controlled objects.

Known communication network management devices containing subscriber lines and communication channels for transmitting information, data acquisition, processing equipment, output means, documenting information and display, operator panels, switching units, threshold circuits, programmable device, fault fixation unit [1, 2] .

However, in such devices considerable time is spent on the formation and transmission of control commands and, in addition, they include a large number of cable lines for receiving signaling about the operation of controlled objects.

There is also a control point for a communication center, a block diagram and description of which is given in [3].

A well-known control center contains: subscriber lines, signal circuits, line input block, line switching shield, telephone sets, office communication panel, light signaling equipment panel, automatic telephone control panel, radio conduit display panel, channel failure time automatic recording unit.

In the well-known control center, the collection of data on the state of communications, channels and terminal equipment from sensors built into the equipment is carried out according to the principle of a wire-command, according to which information from each sensor is transmitted to the control center via a separate wire. This leads to the fact that for the transmission of data on the state of communications, channels and terminal equipment, it is necessary to lay a significant number of signal wires between the control point and the managed objects.

In addition, in the control room, a large number of signals are received on the display device about a change in the state of the managed objects and considerable time is spent for their analysis, which significantly reduces the efficiency of managing the communication network.

The time spent on control and execution of commands (time of the control cycle) can be represented as a sum consisting of the following terms:

T _control = t _ol + t _forms + t _lane + t _isp ,

where: T _exercise. - the total time of the control cycle required for control and execution of commands;

t _CR - the time spent on receiving information from sensors of controlled objects that are part of the mobile communication node;

t _form - the time required for the formation of control commands;

t _pep is the time required to transmit commands to the managed object;

t _isp is the time required for working out the received commands with actuating elements at the controlled objects.

The term of t _forms is the duration of the control system (device) and it includes:

t _forms = t _un + t _sol + t _com ,

where: t _un - time spent on information search of elements on display units and assessment of their condition;

t _re - time required to make a decision;

t _com - time spent issuing commands by controls by pressing buttons, keys.

The calculation of the time t _{type of} information retrieval can be made on the basis of the following expression (see the book "Fundamentals of Engineering Psychology" edited by B.F. Lomov, M., "Higher School", 1977, pp. 38-39).

Closest to the technical nature of the present invention is selected as a prototype integrated hardware communications and radio access, structural diagram and technical capabilities of which are described in RF patent No. 2506723 [4]. This equipment room contains four-wire subscriber (AL) and connecting (SL) lines, two cable entry blocks, a subscriber cross-section unit, a telephone exchange, a telephone operator’s workstation unit, a pairing unit, a line input unit, trunk lines for receiving Ethernet channels, trunk lines for connecting an external automated workstation (AW) of an official (DL), an external AW AW, a channel switching unit, a satellite communication station with an antenna system, two transducers (converters) of the C1-AND interface to the Ethernet interface, two wide-range radio stations with two antennas each, a digital radio relay station with antennas mounted on a telescopic mast, a switching cryptographic router, dispatcher workstation, Ethernet to C1-I interface converter, individual information encryption unit, high-speed information encryption unit, Ethernet switch (LAN), operator workstation a local area network (LAN) switch, a communication server, a GLONASS / GPS navigation receiver with an antenna, a combined multiplexer, a fiber optic communication line (FOCL) for exchange on data with external data transmission devices, wired lines for organizing communication directions using xDSL technology, a remote telephone (TA) of a central office / telephone exchange, a switching unit for service lines (KSL), a TA of an MB system, office communication equipment, a driver and VHF communication panel service communication radio with VHF antenna [3].

The main disadvantages of the well-known integrated hardware communications and radio access are the limited ability to manage communications and communication lines due to the lack of constant monitoring of the state of communication lines and means, as well as data on communication management in the process of deploying the means of a field communication node and operating communication lines.

A comparable analysis with the prototype shows that the invention is characterized by the presence of new units: three automated workstations of technological control operators (AWP OTU) equipped with laptop computers, two automated workstations (AWP) of a telecom operator equipped with laptop computers, a printer, a video monitor, a packet switch, a second switching unit, four operational telephone sets (SLTs), a second LAN switch, a trunk (SL) for connecting I have an external multifunctional terminal (MTU), a digital communications switch, a fiber optic link for transmitting E3 group stream signals, a fiber optic link for transmitting E1 group stream signals and wire service lines, making an exchange telephone exchange in the form of a multifunctional terminal device (MTU), as well as changing connections between known hardware units.

Thus, the claimed mobile communication control hardware meets the criteria of the invention of "novelty." Comparison of the proposed solutions with other technical solutions shows that the introduced blocks and devices are widely known and additional creativity for their implementation is not required. However, when new units are introduced in this connection with the remaining elements of the circuit into the claimed mobile communication control hardware, the above blocks exhibit new properties consisting in increasing the efficiency of monitoring and control of the system and communication nodes in the conditions of dispersed deployment of communication means over a large territory.

The claimed combination of elements and connections allows us to achieve this goal due to the original combination of instruments and devices used in public telephone networks, both in their direct and non-standard applications.

The proposed solution is significantly different from the currently known solutions. The proposed mobile communications control equipment allows, in contrast to the prototype, the deployment of several communication networks, including: the deployment of a control center for the communication center and the control center of the transport network of the field communication system, the ability for communication officials to automatically perform functions for the operational, technical and technological management of the node and communication, to provide work both in the parking lot and in motion with the possibility of transmitting various types of information via educated communication channels and expand the scope and quality of services provided by communications officials. This allows us to conclude that the proposed mobile complex of means of operational communication meets the criterion of "significant differences".

The claimed solution explicitly does not follow from the prior art and has an inventive step.

The inventive mobile communication control apparatus can be implemented using existing apparatus and equipment, electrical and communications, computer technology and is industrially applicable.

2) the formation of two field cable communication lines (PCLS) using xDSL equipment when working on light field two-wire cables of the P-274M type with the formation in the PCLS of an E1 digital stream with a transmission speed of 2.048 Mbit / s, which allows the transfer of Ethernet packets;

accounting for the composition and structure of the resources of the node and communication system; monitoring the status and use of system resources (communication node); operational and technical management of system resources; accounting for statistical information on the status and use of system resources;

Service communication is carried out through the exchange of voice information using packet transmission between communication officials of the field communication node and communication officials of the interacting (corresponding) CSS.

The positive effect of the proposed mobile hardware communication control is to increase the efficiency of control of the node and communication system, achieved by significantly reducing the analysis time of the status of equipment, channels, lines and directions of communication, the possibility of obtaining a generalized estimate for each line in the direction of communication and reducing time formation and communication of control teams to managed facilities.

Calculations showed that when using the proposed mobile hardware communications control, the transfer of commands to establish new and restore broken connections on the network can be carried out in a few seconds (almost in real time), while in the prototype this time is several minutes, especially when work with remote objects. In this case, we obtain a significant reduction in the time for transmitting control commands and, accordingly, a significant decrease in the total time of the control cycle of the node and communication system in the process of establishing new and restoring broken communications.

Reducing the time to establish communication on the network allows, along with increasing the efficiency of communication management, to also facilitate the work of operators by automatically performing part of the operations (searching and analyzing incoming information) for controlling the hardware devices themselves.

The advantage of mobile hardware communications management is that it expands the ability of officials to exchange information. Officials on the portable computers of their workstations can receive telex and fax messages, various kinds of graphic information and other operational information, which also increases the efficiency of managing the node and communication system.

Tests of a model of mobile hardware communications control confirmed the correctness of technical solutions, the operability of apparatus and equipment hardware and its industrial applicability.
