The areas of application of "Elod-160MC" can be the following:

- sounding of open spaces: infrastructure facilities of JSC Russian Railways, transport highways, construction sites, bridges, hydraulic structures;

- coordination of personnel actions when carrying out work in noisy places;

- dispatch radio communication;

- increasing the safety of work during track repairs and scheduled track work, when installed on special rolling stock, on fire and recovery trains;

- scoring of guarded railway bridges and structures, warehouse areas and container sites;

- sounding of the territory (commands from the work manager from the console or via radio);

- the ability to notify about the approach of a train by voice or siren and optical signal from a portable radio station at a distance of up to 6 km from the work site, depending on the topography of the area, the siren is turned on by one press of a button on the portable radio station;

- radio communication with a portable radio station at a distance of up to 6 km, and with mobile and base radio stations at a distance of up to 25 km, depending on the topography of the area;

- the possibility of using as part of an automated warning system for workers about the approach of rolling stock (ASO), for example, such as SORZH, SORBIS and SOMP. Notification of workers on railway tracks occurs due to the installation of a sensor that detects the approach of railway rolling stock to the place of work, connected by a radio communication channel to a central control unit located in the work area, generating and automatically transmitting information warning signals via radio channel to those located in in the work area, sirens that generate and reproduce certain acoustic and optical signals. The proposed system, Elod-160MC, located within the radio access zone of the central control unit, can be used as a siren;

- presence of functions: automatic self-monitoring, receiving and playing control signals from the automatic control system, receiving turn-on signals and playing a siren, turning on optical warning signals;

- the possibility of use as part of automated control systems, such as SORBIS and SOMP, which are designed to fence the work site on the stretch and notify those working on the railway tracks about the approach of railway rolling stock without the use of signalmen. The proposed device, Elod-160MC, can be used as a signaling device, which is installed on track machines and is located in the radio access zone of a collective portable signaling device (KPS-L). The signal about the approach of a train comes to KPS-L from sensors installed on the rails, and is transmitted by a special signal to Elod-160MC. At the same time, flashing beacon 11 is turned on on Elode-160MC, and the “Siren” signal is broadcast through loudspeakers 13÷17.

The remote radio warning and public address system works as follows.

Operating mode as part of ASO (SORZH, SORBIS and SOMP).

As part of the ASO, the proposed ELOD-160MC system is used as a collective siren. From the ASO, the warning signal about the approach of rolling stock is sent through the antenna to the digital radio modem 3, then upon receiving an executive signal from the digital radio modem 3, the controller 6 generates a command to play the “Siren” signal, which is sent to the input of the sound synthesizer 5, which generates the “Siren” sound signal ", which is supplied to the input of the low-frequency amplifier 12. After amplification, the electrical sound signal “Siren” is supplied to the inputs of loudspeakers 13÷17, which convert it into an acoustic signal “Siren”. Simultaneously with the formation of the acoustic signal “Siren”, controller 6 turns on the flashing beacon 11.

Mode for transmitting voice messages via radio channel.

The radio station 1 receives voice messages transmitted over the radio channel, converts them into low-frequency electrical signals, which are fed to the input of the sound synthesizer 5, from the output of which they are fed unchanged to the input of the low-frequency amplifier 12. After amplification to the required level, which can be changed by the user, the amplified voice signals are fed to the inputs of loudspeakers 13÷17, which reproduce the transmitted messages in acoustic form.

Mode for transmitting voice messages from a microphone 4.

Microphone 4 perceives the voice message transmitted by the user, converts them into electrical signals that are supplied to the input of the sound synthesizer 5, from the output of which they are fed unchanged to the input of the low-frequency amplifier 12. After amplification to the required level, which can be changed by the user, the amplified voice signals are fed to the inputs of loudspeakers 13÷17, which reproduce the transmitted messages in acoustic form.

Siren signal mode.

When you press button 8 “Siren” on the front panel of the device or additional remote buttons 9, 10, controller 6 generates a command to play the “Siren” signal. The electrical signal “Siren” is supplied to the input of the sound synthesizer 5, which generates the sound signal “Siren”, which is fed to the input of the low-frequency amplifier 12. After amplification, the electrical signal “Siren” is supplied to the inputs of loudspeakers 13÷17, which convert it into an acoustic signal “Siren”. Simultaneously with the formation of the acoustic signal “Siren”, controller 6 turns on the flashing beacon 11.

Horn signal mode.

The “Horn” signal mode is activated by pressing button 7 “Horn” located on the front panel of the device. Otherwise, the algorithm for operating the system in the Horn signal mode is similar to the algorithm for operating in the Siren signal mode, with the exception that the sound synthesizer 5 generates the Horn sound signal.

Mode of remote activation of the special signal “Siren”.

The radio station 1 receives a tone signal of a certain frequency transmitted over the radio channel, demodulates it and transmits it to the input of the sound synthesizer 5, which generates the “Siren” sound signal, which is fed to the input of the low-frequency amplifier 12. After amplification, the electrical signal “Siren” is supplied to the inputs of loudspeakers 13÷17, which convert it into an acoustic signal “Siren”. Simultaneously with the formation of the acoustic signal “Siren”, controller 6 turns on the flashing beacon 11.

Controller 6 has added memory - an SPI (Serial Peripheral Interface) Flash chip for archiving system state events, capable of recording at least 10,000 events with the ability to adjust the time zone. Recording is performed cyclically: when the end of the archive is reached, the oldest records begin to be overwritten (with the ability to select write protection against erasure). Opportunities for working with the archive include viewing the event archive, searching for events by name or date/time, exporting the archive to a CSV file, importing the CSV file back into the program, setting the date/time and time zone, enabling and disabling time synchronization via GLONASS/GPS .
