The present invention relates to electrical engineering and communication, in particular, to a field communication system and can be used to provide control of receiving and transmitting centers, for transmitting (receiving) data over a data exchange network, and forming remote control lines.

An analogue of the claimed system is the field switching center N-14 PBIN.3512.001.TU developed by the Scientific Research Institute "Automation", Moscow. It includes the field cross P-247 PEA.4383.000.TU, the remote control device for the receiving P-604 SFK.1035.000.TU and the transmitting centers P-605 SFK. 1026.001.TU development of the Mytishchi communication equipment repair plant, Moscow region. and other elements. The P-247 field junction and the P-605 remote control device ensure the distribution of communication channels to control rooms, the formation of telephone and telegraph channels, automatic control over channels, and measurement of channels. In their composition, they contain equipment for frequency separation of channels, a cordless device for switching channels, cable glands and other elements.

The disadvantages of a field switching center include: long time of channel switching, bulky power equipment, low channel capacity, and a large number of service personnel.

The existing remote control system P-604 SFK.1035.000.TU, consisting of an analog radio relay station for the formation of analog channels, equipment for frequency separation of channels, cable input and a manual channel switch. This system is a prototype of the proposed technical solution. It serves for remote control of the receiving means of the field communication center, the organization of radio relay and cable communication lines, the reception and transmission of service and operational information. The disadvantages of this system include:

- long time of channel switching;

- large specific energy consumption per channel;

- bulky equipment;

- low reliability of the MTBF equipment;

- a large number of service personnel.

The aim of the invention is to increase the speed of channel switching at the field communication node while increasing the reliability of the equipment, as well as to reduce the number of vehicles, energy consumption and maintenance personnel.

This goal is achieved by the fact that a remote control system for a field communication center, containing an analog radio relay station, frequency division equipment, the first automatic channel switch and cable input, additionally introduced a digital radio relay station, time division equipment, data transmission equipment, a specialized computer and the second automatic channel switch, while both channel switches are made on a special processor of the "RAMEK-113" type, the outputs of the radio relay stations through the first channel switch are connected to the equipment of frequency and time separation of channels, the inputs of which are connected to the second channel switch, the outputs of which are connected to the transmission equipment data connected to a specialized machine, and the inputs of the second switch are connected to the cable gland.

The drawing shows a block diagram of the proposed system for remote control of a field communication center. It contains:

1 - cable gland;

2 - automatic channel switch # 2;

3 - equipment for time division of channels;

4 - automatic channel switch # 1;

5 - analog radio relay station;

6 - data transmission equipment;

7 - equipment for frequency separation of channels;

8 - digital radio relay station;

9 - a specialized computer.

Cable gland 1 is used to provide reception of telegraph channels (TC), telephone channels (PM) and digital channels (C1I) from 1.2 kbps to 48 kbps. Automatic switch of channels 2 provides switching of digital signal transmission means at 1, 2 steps in the interests of equipment redundancy, as well as in the interests of ensuring the prompt interception of certain transmitting groups in the interests of a priority communication post. The remote control system uses two automatic channel switches of the Mezha-1 type (one 128 × 128 channels, the other 16 × 16 channels). The equipment for time division of channels 3 is used to ensure the reception of subscriber channels, bring them to a single group rate E1 and issue in the appropriate direction. For this, the channel-forming equipment, the primary multiplexer of the MP-2 type, is used. Digital radio relay station 8 of the "Rokada-RRS" type is used to operate in 4 directions in the range from 7.98 to 8.4 GHz. Analog radio relay station 5 of the R-415B type with a directional antenna DB-11 in the range from 390 to 430 MHz is used to create analog channels. Frequency division equipment 7 serves to separate analog and digital channels. Specialized computing machine 9 of the "Baguette-11" type is designed to provide automated switching on requests, according to the program and to monitor the technical condition of the equipment. In addition, it is designed for automated control of a communication center in an ACS system. It also generates and commutes group information flows to various communication directions and provides the formation, using primary digital multiplexers, of four group E1 streams from voice frequency (PM) and telegraph channels (TC), automated control of flow switching using a specialized computer 9 V according to the provided algorithm. The computing core of this machine is built on a special processor of the RAMEK-113 type. With the help of a switch, it is connected to the control modules of the primary multiplexers MK8 and the switch of group flows KCS. Switches provide formation and switching of group flows in accordance with control commands coming from the operator's terminal through a special computer 9. Zexel's-1612 multiplexers are designed to organize highly reliable distributed modem networks and multi-line switching nodes. From the side of the computer 9, the control unit via the RS232 interface. The unit is equipped with five U-336R modems and provides operation on 2-wire dial-up and 2-4-wire dedicated lines with a speed of 300 to 33600 bit / s, depending on the used exchange protocol in synchronous and asynchronous modes of operation.

The data transmission equipment 6 serves for the service exchange of messages in the data exchange network between the hardware of the field communication center in the interests of the functioning of the ACS.

An essential feature is that the remote control system of the field communication center includes a specialized computer 9 with special software and data transmission equipment that provides automated information and technological communication as part of a field communication center. The equipment of the remote control system of the field communication center is located in one KK 4.2.00.2 container body, the base of the KamAZ-43114 chassis with life support and power supply equipment.

The positive effect in comparison with the prototype is expressed in the reduction of the required number of field hardware rooms, personnel, in the increase in the throughput of the system, in the reduction of energy consumption. This system is implemented in one vehicle.
