Description

The utility model relates to alarm devices and is intended for local or remote speech, light and sound alerts to the public, employees of enterprises about emergency or emergency situations, the transmission of warning signals and messages, as well as service teams during the production of repair and other types of work.

Known light and sound siren, comprising a housing, sources of light and sound and power supply (patent RU 85731, CL G09F 13/06, publ. 10.08.2009). However, such an annunciator has large sizes and limited functionality and is not sufficiently protected from external influences.

The technical problem is the elimination of the noted deficiencies. The technical result consists in expanding the arsenal of signaling devices in the field of emergency or emergency situations.

The problem is solved, and the technical result is achieved by the fact that in the annunciator combined for issuing light and sound signals, comprising a housing, light and sound sources and a power supply, the housing is made of dust and moisture-proof galvanized steel with a minimum thickness of 2 mm; a voice module and a low-frequency amplifier with a capacity of at least 200 W, an automatic volume level control board is integrated into the board, and a 220 V power supply unit is equipped with a rechargeable battery An awn of not less than 9 Ah at a voltage of not less than 36 V and is located in the battery compartment of the case, which is equipped with a thermostat to maintain a positive temperature. The siren can be equipped with a radio station with a built-in optional board and receiving antenna, an external LED lamp with a luminous intensity of 3500 Lm, having a self-monitoring and diagnostics function, a built-in matching transformer to enable connection of the output amplifier of the broadcasting line with a voltage of 100 V, a LAN connection board that performs the scheduling of the siren over the local network, the call panel for communication of the siren with the dispatcher and the sun-protection cover.

FIG. 1 shows the appearance of the proposed siren; FIG. 2 - the same, with a sun-protection cover, on fig. 3 is a block diagram of the siren.

The siren contains a dust and moisture proof housing made of galvanized steel with a thickness of at least 2 mm of IP65 standard. In the case there is a controller board with a built-in voice module and a low-frequency amplifier with a capacity of at least 200 watts. An automatic volume control board is integrated into the board, which allows the device to automatically shoot the background noise level and adjust the output level of the amplifier in accordance with the background noise indicators. This feature is required to use alerts in areas with a changeable level of background noise (railway, motorways, airports, etc.). The 220 V power supply unit is equipped with a battery with a capacity of at least 9 Ah at a voltage of 36 V and is located in the battery compartment of the case, which is equipped with a thermostat to maintain a positive temperature at negative ambient temperatures, which allows the siren to work autonomously for 24 hours in standby mode and 1 hour in alert mode.

The annunciator is additionally equipped with a DMR radio station with a built-in optional board and a receiving antenna. With the help of a radio station, the system receives alert signals and sends monitoring information about the system status to the dispatcher. In addition, the internal memory of the radio station contains up to 15 audio messages that can be played by the dispatcher’s command, or from a portable radio station also equipped with an optional card.

An external LED lamp is included in the siren. With a high noise level, a bright LED lamp is used to attract attention, the intensity of which is about 3500 Lm, which makes it possible to see the warning signal even in bright sun. It has the function of self-monitoring and diagnostics. In cases of malfunction of the light alert, a signal will be sent to the dispatcher.

The siren has an integrated matching transformer for connecting the output of the amplifier to a 100 V transmission line. If necessary, a more uniform sounding of the territory is provided for a matching transformer that matches the signal level of the power amplifier with a 100 V signal of the broadcast line. Additionally, galvanic isolation of the transmission lines from the power amplifier is carried out.

The siren includes a LAN connection board. This option allows you to dispatch a warning system on the local network.

The call panel is included in the siren, which is intended for the connection of the subscriber who is directly at the warning system with the dispatcher. With it, you can call the dispatcher and provide the necessary information. The dispatcher can communicate with the subscriber by speakerphone.

For regions with hot climates, a sun cover is provided to protect the device from direct sunlight and overheating.

There are 3 options for the device:

on "dry" contacts;

Ethernet interface;

over the radio DMR.

According to the first and second options, most modern warning systems work. To work in these modes requires the installation of cable routes. The proposed siren provides the ability to wirelessly transmit signals over a radio network in the DMR standard. The distance between the control tower and the terminal device can reach 60 km (via a repeater). At the same time, there is no need to lay cable routes; only a connection point to the 220V power network is needed. This circumstance is the main advantage of this solution in the alert system.

In order to comply with the requirements of GOST R-42.3.01-2014 "TECHNICAL MEANS OF PUBLIC NOTIFICATION", namely the requirements for feedback of the terminal device with the dispatcher, the siren sends periodic packets with the device status data and messages about the processing of the warning signals. To this end, an expansion card (manufactured by NEOKOM LLC) is built into the digital mobile radio station that is on board. Using it, telemetry data on the status of the siren is transmitted to the dispatcher. Interrogation of terminal devices is carried out with a certain frequency for the rapid detection of possible faults. This increases the reliability of the warning system as a whole. In addition, the expansion card allows you to divide the end devices into groups and one by one for the selective transmission of alert signals.

Also, in accordance with GOST R-42.3.01-2014, in addition to feedback, it is necessary to ensure the autonomy of the device for at least 6 hours in standby mode plus 1 hour in data transfer and alert mode. The annunciator has autonomy at the level of 24 hours in the standby mode plus an hour in the alert mode, which exceeds many analogs. This is achieved by installing a 9Ah lithium-iron-phosphate battery into the notification device, designed by the specialists of NEOKOM LLC, with a capacity of 9Ah at a voltage of 36V and relatively small size relative to lithium analogs, as well as an increased number of charge / discharge cycles at the level of 5000 times.
