Description

The invention relates to the field of telecommunications and is intended for organizing loud-speaking park communication at railway stations having one or more technological parks, at freight yards, railway stations, depots, and industrial enterprises.

A known method of acoustic warning, implemented by a device for acoustic warning, consisting in the use of intercom units connected through central switches with amplifiers connected to loudspeakers (see Kashirskaya MS and other loud-speaking communication in railway transport. M .: Transport, 1974 , p. 153-164.)

The disadvantages of this method are the significant difficulties of providing acoustic warning of large areas and the creation of significant acoustic noise.

A known method of acoustic warning, implemented by the known device for acoustic warning, consisting in the use of intercom units connected through central switches with amplifiers connected to speakers and inductive communication devices (SU 706936 A, 12/30/1979).

The disadvantages of this method are the significant difficulties in providing acoustic alerts and negotiations with performers of large areas.

The known method of station two-way park communication, implemented using known equipment of station two-way park communication modernized "SDPS.M 2" (see Technical description 38130-00-00 TO 1995, TU32TSSh 3744-95.0KP 318582).

Using well-known equipment, station speaker systems of varying complexity are organized depending on the design of the designed railway station, the number of commanders, public address lines and park intercoms, while peripheral intercoms: commander consoles and park intercoms are connected through distribution amplifiers .

However, the known method does not provide adequate flexibility in choosing the optimal notification mode in the absence of an intercom at a given station zone. In addition, the known method uses equipment, the energy consumption of which is quite high.

The closest analogue to the invention according to the set of essential features and functional capabilities is the method of station two-way park communication with digital switching, implemented using equipment of station two-way park communication with digital switching (Vokhmintsev S.V. et al.

To organize a station two-way park communication system is used as follows.

For a loud-speaking notification, the head, using the remote control 10, connects feeder lines (not shown in the drawing), which will be used for notification, turns on the control signal and transmits a message through the speakers in the park, while the operation mode is “loud”, and the feeder lines are only busy for the duration of the control signal. If necessary, the leader invites the performer in the park to connect to the communication line. The contractor in the park from one of the intercoms 8 is connected to the communication line and answers to the leader. If the subscriber is located far from the intercom 8, he is using the wearable radio access device (not shown in Fig.) Through the radio access device 15 to the leader. During negotiations between the leader and the executor, the leader switches on the quiet operation mode.

For loud-speaking notification from the artist in the park, the subscriber presses the corresponding button on the intercom 8 and transmits a message through the speakers in the park. In this case, the feeder lines are occupied only for the duration of the control signal, and the loudspeaker located in the immediate vicinity of the intercom from which the notification is made is switched off to avoid acoustic feedback.

To communicate with the leader or dispatcher, the executor in the park presses the corresponding button on the intercom 8 and calls the leader for negotiations with his voice. When the leader answers, the quiet operation mode is automatically turned on, and negotiations are carried out through the loudspeaker built into the intercom 8.

For communication between intercoms in the park, the subscriber presses the loud-speaking notification button on the intercom 8 and voice invites the performer in the park to approach one of the intercoms. The answering agent answers from the nearest intercom in silent or speakerphone mode.

To call the head (dispatcher) by the performer via a radio channel, the performer sends a call from the portable radio access device and calls the head for negotiations by voice. When the manager answers, the quiet operation mode is automatically turned on.

For loud-speaking notification from the performer from a portable radio access device, the subscriber sends a call, the control device automatically commutes the incoming call to the broadcast loudspeaker notification amplifier and transmits a message through the speakers in the park, while the feeder lines are busy only for the duration of the control signal.
