Description

The invention relates to communication technology and can be used to transmit and / or receive information between subscribers of a fixed communication network and subscribers located in a moving object, for example, a train.

A known satellite communication system comprising at least one subscriber station, at least one satellite, at least one gateway station containing a radio frequency transceiver for establishing and maintaining communication with a subscriber station through at least one satellite via an incoming communication line and an outgoing communication lines, while the gateway station is connected to the data network and further comprises a unit for determining the number of units of transmitted data that were used during the communication session of at least one of the incoming and outgoing lines; and a unit for determining the amount of the bill for the communication session at least partially based on the specified number of units of transmitted data.

The known system does not allow for high-quality communication between subscribers of a fixed communication network and subscribers located in a moving object, for example, a train, and also does not provide voice telephone communication.

The problem solved by the utility model is to provide reliable voice telephone communication between subscribers, one of which is located in a mobile facility.

The problem is solved due to the fact that, in a voice telephone communication system in a movable object containing a DC power supply installed in the rolling stock, a voltage converter, a satellite terminal, an external antenna, a payphone, an incoming office telephone, according to a utility model, the converter is connected to DC power supply and is connected to a satellite terminal, to the output of which a remote antenna is connected, a payphone and an incoming office telephone are connected to the interface satellite terminal.

Cellular operators are not able to provide reliable communication along the whole train travel path due to the long distance, therefore the satellite system is currently a worthy proposal to address the issue of providing communication services for train passengers. So, the coverage area of satellite communications Globalstar

includes space from 74 ° N 74 ° S, i.e. only the north and south poles are not covered.

The proposed utility model allows for reliable uninterrupted communication along the entire train travel path through the use of satellite communications.

The system is assembled on site. A stabilized voltage source is installed - a converter designed to convert, depending on the system configuration, 110 V DC (or 220 V AC) into 12 V DC. The output for the satellite terminal for receiving / transmitting information in the frequency range 2.5 / 1.6 GHz is removed from the converter output (Globalstar mode). A telephone set is connected to the satellite terminal through the interface, designed to receive incoming calls and to charge them.

The telephone set designed to work in the system should work in tone mode, as a tone signal should be sent to the interface of the satellite terminal, in this case, high-quality communication is guaranteed.

The payphone is installed parallel to the telephone with the ability to pay for negotiations with an electronic debit card.

The system includes the need to install a circuit breaker designed to protect against overloads and short circuits.

An analysis of known technical solutions in this area did not reveal devices characterized by the claimed combination of essential features, therefore, the proposed voice telephone system in a mobile network meets the patentability criterion of “novelty”.

The possibility of industrial use of the claimed technical solution allows us to conclude that it meets the patentability criterion of "industrial applicability".

The invention is illustrated in the drawing. Figure 1 presents a General diagram of the system.

The inventive system comprises a satellite terminal 1, a converter 2, a circuit breaker 3, a power supply 4, a telephone set 5 with tone dialing for incoming calls, a payphone 6, an external antenna 7.

The following types of equipment can be selected as elements of equipment for the system:

- satellite terminal 1 - GSP 2800 (universal);

- Converter 2 - 110 / -12V DC;

- circuit breaker 3 - 16A / 10 ";

- power supply 4 - electric shield of the car (depending on the brand of the car);

- telephone set 5 with tone dialing - any device that has a tone dialing function;

- payphone 6 - UTEK-002-02 "multi";

- remote antenna 7 - GSP 1620 DRA.

The output of power supply 4 is connected to the input of converter 2. The output of converter 2 is connected to the input of satellite terminal 1, to the output of which a remote antenna 7 is connected.

Payphone 6 and telephone 5 are connected to the RJ11 interface of satellite terminal 1. Circuit breaker 3 protects against voltage overloads and short circuits:

- up to 110 V DC;

From the output of the power source 4, the voltage is supplied to the input of the converter 2. Converter 2 converts a constant voltage of 110 V into a constant voltage of 12 V, which is necessary to power the satellite terminal 1.
