The essence of the invention is illustrated by drawings in Fig. 1 and 2. FIG. 1.the structural

- 1 039040 diagram of the proposed system of two-way park communication, in Fig. 2 is an embodiment of an active loudspeaker with a radio module.

The two-way park communication system contains (Fig. 1) a switch 1, control panels 2 for managers, a park communication transceiver 3, a portable radio station 4 for the operational work performer, park intercoms 5, an individual radio receiver 6, built into the signal vest of each operational work performer with an external side of the vest with a low-power loudspeaker 7, an active loudspeaker 8 with a radio module, a controller 9 connected to base radio stations 10 according to the DECT standard, connected by radio with wireless park intercoms 11, a receiver 12 of park communication signals, the output is connected to the input of the switch 1 and connected by a radio channel with park communication transceiver 3.

In this case, the inputs / outputs of the switch 1 are connected to the outputs / inputs of the consoles 2 of the managers, the transceiver 3 of the park radio communication, the controller 9 and the park intercom 5.

The wearable radio station 4 of the performer of operational work, the individual wearable radio receivers 6 and the radio module of the active loudspeaker 8 are connected via a radio communication channel with the transceiver 3 of the park communication.

The active loudspeaker 8 includes a series-connected radio receiving module 13 for park communication signals and a controller 14, connected via a signal circuit and a control circuit to the amplifier input 15, through a connection element 16 connected to a loudspeaker 17 or to a loudspeaker feed line 18, and a power supply unit 19 connected to the power supply.

In this case, the radio receiving module 13 of the park communication signals, the controller 17, the amplifier 15, the element 16 and the power supply unit 19 are placed in a single housing 20, on the outside of which a loudspeaker 17 is installed.

The system can include a conversation recorder connected to the corresponding switch output (not shown in the drawing).

The station two-way park communication system operates as follows.

Each performer of operational work located on the territory of the railway station is equipped with an individual wearable receiver 6, built into the signal vest and connected to a low-power loudspeaker 7 mounted on the outer side of the vest.

Commands and messages of the managers of the operational work of the station come from the intercom-calling console 5 through the switch 1 to the input of the transceiver 3, transmitting radio signals perceived by individual portable radio receivers 6, which reproduce the corresponding speech signals with the help of loudspeakers 7.

The commands and messages transmitted by the transceiver 3 are also received by the radio receiving module 13 of the active loudspeaker 8 and are reproduced by the loudspeakers 18 of the feed line or loudspeaker 17 connected to its outputs.

The active loudspeaker 8 is used in such zones of the station (passenger platforms, service passages, etc.) in which the persons in them cannot be equipped with individual portable receivers 6.

Each individual wearable receiver 6 and an active loudspeaker 8 are tuned to receive and reproduce the head's speech signal transmitted in a circular mode or for a specific group of receivers 6 (up to 10 groups).

The answer or call to the executive head is carried out either using the park intercom 5 installed on the territory of the station, connected to the switch 1 using wired lines, or using wireless park intercom 11, interacting with the intercom 2 through the base station 10 according to the DECT standard , controller 9 and switch 1, or with the help of a portable radio station 4 attached to individual performers (team leaders), interacting with the intercom 2 through a stationary transceiver 3 and switch 1.

Transmission of the performer's response to the leader who called him can be carried out without broadcasting via the park communication channel (quiet communication mode) or with broadcasting via the park communication channel (speakerphone mode). In the hands-free mode, the performer can call another performer for negotiations.

To control the functioning of the transceiver 3 in the system, a stationary receiver 12 is used, which receives the signals of the transmitter 3 and transmits the corresponding information to the remote control 2.

Active loudspeaker 8 functions as follows.

Messages or commands transmitted over the radio channel from the console 2 are received by the receiving module 13 (Fig. 2), from the output of which the signal is sent to the controller 14, which analyzes the received call. If a signal is received, transmitted in a circular mode or for a specific group of receivers, which includes an active speaker 8, the controller 14 turns on the amplifier 15.

From the second output of the controller 14, the speech signal is fed to the input of the amplifier 15 and is reproduced either by the loudspeaker 17 or by the feeder line 18.

The power supply unit 19 provides a DC voltage supplied to the elements included in the active loudspeaker 8.

Thus, the proposed system makes it possible to improve the conditions for the perception of commands and messages from managers by the executors located in the parks of the railway station, to eliminate acoustic interference in the residential areas adjacent to the station and to reduce the cost of construction and technical operation of the two-way park communication system.
