Abstract

FIELD: acoustics.
SUBSTANCE: invention relates to acoustics, in particular to horn loudspeakers. Acoustic warning unit comprises a coiled horn with a small cross-sectional area of the output of the sound head and exponential expansion of the sound channel in the inner space of the horn. Besides, it comprises the control board, accumulator battery and cable arranged in aluminum housing and interconnected control board. Control board includes microprocessor, power amplifier, secondary power supply elements, as well as a battery charger, wherein heat removal from the microprocessor is provided directly to the horn aluminum housing, and command and power supply to control board by cable is carried out by means of PoE function.
EFFECT: technical result consists in improvement of efficiency of the annunciator with reduction of dimensions and weight of the declared device.

Description

Изобретение относится к области радиотехники и может быть использовано в системах безопасности в качестве оповещателя о различных угрозах.The invention relates to the field of radio and can be used in security systems as an annunciator of various threats.

Из уровня техники известны различные системы оповещения населения. Например, из патента US 9014389 В2 (опублик. 21.04.2015), известно изобретение, которое относится к мегафону, который состоит из корпуса, двух противоположных ручек и рупора, и дополнительно содержит бампер обода, прикрепленный к концу рупора.From the prior art there are various public alert systems. For example, from patent US 9014389 B2 (published April 21, 2015), an invention is known that relates to a megaphone, which consists of a body, two opposite handles and a horn, and further comprises a rim bumper attached to the end of the horn.

Целью заявленного технического решения является создание оповещателя о различных угрозах.The purpose of the claimed technical solution is to create an annunciator of various threats.

Решение задачи достигается тем, что блок акустического оповещения со свернутым рупором с небольшой площадью сечения выхода звуковой головки и экспоненциальным расширением звукового канала во внутреннем пространстве рупора, содержит расположенные в алюминиевом корпусе (3) и взаимосвязанные плату управления (1), аккумуляторную батарею (2), кабель, при этом плата управления (1) включает в себя микропроцессор, усилитель мощности класса D, элементы вторичного питания, а также зарядное устройство для аккумуляторов, причем отвод тепла от микропроцессора обеспечивается напрямую на алюминиевый корпус (3) рупора, а подвод команд и питания к плате управления за счет кабеля категории 5 (4) происходит посредством функции РоЕ (Power over Ethernet). Для обеспечения устройства достаточной мощностью применяются Li-Pol батареи (2).The solution of the problem is achieved by the fact that the acoustic warning unit with a rolled horn with a small cross-sectional area of the sound head output and an exponential expansion of the sound channel in the internal space of the horn, contains located in an aluminum case (3) and interconnected control board (1), battery (2) cable, while the control board (1) includes a microprocessor, a class D power amplifier, secondary power supply elements, and a battery charger, and the heat removal from the micro the processor is provided directly to the aluminum case (3) of the horn, and the supply of commands and power to the control board by means of a category 5 cable (4) occurs through the PoE (Power over Ethernet) function. To ensure the device with sufficient power, Li-Pol batteries are used (2).

Технический результат заключается в повышении эффективности оповещателя при уменьшении габаритов и веса заявленного устройства.The technical result is to increase the efficiency of the siren while reducing the size and weight of the claimed device.

На фиг. 1 представлена структурная схема блока акустического оповещения со свернутым рупором, где под указанными позициями обозначены следующие конструктивные элементы:FIG. 1 shows a block diagram of an acoustic warning unit with a collapsed horn, where the following structural elements are indicated below the indicated positions:

поз. 1 - плата управления;pos. 1 - control board;

поз. 2 - аккумуляторная батарея;pos. 2 - rechargeable battery;

поз. 3 - алюминиевый корпус;pos. 3 - aluminum case;

поз. 4 - кабель 5 категории.pos. 4 - Category 5 cable.

При использовании свернутого рупора с небольшой площадью сечения выхода звуковой головки и экспоненциальным расширением звукового канала возможна установка всех компонентов, обеспечивающих работоспособность устройства в указанных габаритах, так как во внутреннем пространстве рупора остается достаточно места для размещения аккумуляторной батареи, микропроцессора и усилителя мощности, что позволяет при использовании современной базы микроэлектронных компонентов создать сиренно-речевую установку оповещения и громкоговорящей связи небольших габаритов и веса, с управлением по каналам передачи данных Ethernet и питанием по РоЕ.When using a folded horn with a small cross-sectional area of the sound head output and an exponential expansion of the sound channel, it is possible to install all the components that ensure the device’s operability in the specified dimensions, since there is enough space in the inner space of the horn to accommodate the battery, microprocessor and power amplifier, which allows Using a modern base of microelectronic components to create a lilac-speech alert setting and a speakerphone and small dimensions and weight, controlled via Ethernet data transmission channels and PoE power supply.
