Sistemar Annunciation da Alarm Annunciator

A cikin kungiyoyi da tattalin kasa, sunan Annunciator yana nufin wurare da ya fi sani da hankali ko abubuwan da ba a gaisa su ne wanda suka shafi na musamman.

Muhihimmiyar Alarm Annunciator

Yana daya daga cikin abubuwa da aka fahimta, yana nufin ita ce mai karatu da ma'afata, wanda ya fi sani da hankali ko abubuwan da ba a gaisa su ne, ko kuma idan akwai hankali. Wannan yana bukatar don dalilin hankali, kuma yana iya haɗa da hankali a baya game da tsarin da ba daidai ne, wanda ya fi sani masu amfani da shi don kula da hankalin da ba a gaisa su ne. Wannan shine muhihimmiyar Alarm Annunciator, da alarm annunciation system. Za a duba aiki na wasu wuraren alarm annunciator.

Aiki na Alarm Annunciator

Alarm Annunciation System

Don in fahimta aiki da tasiri na alarm Annunciator, za a fahimta muhihimmiyar alarming system a cikin tsarin monitoci. Idan karamin electromagnetiko ta kasance da takarda, yana yi aiki da electromagnet don wani abu. Daga baka, saboda takarda mai yawa, wata batu a kan karamin electromagnet an fara. Tabbacin haka, duk abubuwan da suka shiga suka zama da ala'ada. Saboda haka, idan kana tabbaci sababin wannan ala'ada, za a duba kowane batu a kan wurar da kake so in tabbaci da kumshi. Idan kana da 50 karamin electromagnet, za a duba kowane karamin da kake so in tabbaci, zai zama da rashin kawo kofin da kuma lokaci.

Amma idan kana sama da bulb da kake bayyana da takarda a kan karamin electromagnet, zai yanfi idan karamin electromagnet yana yi aiki da kima. Hakan, don 50 karamin electromagnet, za a samun 50 bulb, kowane bulb da kake bayyana da karamin electromagnet, inda za ku iya tabbaci aiki da kima. Wannan shine muhihimmiyar da kuma babban model na monitoci.
Alarm Annunciator yana daya daga cikin abubuwan da ke bayyana da audio visual signals don abubuwan da ba a gaisa su ne. Modelin da yanzu ana amfani da su suna da microprocessor ko microcontroller circuitry, wanda ke tabbatar da inganci da kuma kisan abubuwan da kuma funtuka.

Tsari na Alarm Annunciator

Akwai nau'o'i biyu na ita ce mai karatu da ma'afata, su ne input fault contacts da output relay changeover contacts. Input fault contacts su ne simple connection normally open (ko NC Selectable) da common C contact. Yawanci waɗannan input fault contacts su ne potential free contacts. Lissafin haka, idan kowace fault contacts da common contact C an samu short circuited, fascia ko fault window yana faru da kuma output relay contact zai changeover instantly.

Idan kana amfani da 8 windows annunciation system, yana nufin an tabbaci 8 aiki a baya. Idan kana sama F1 (fault 1) da over voltage alarm na motor 1, da kuma F2 (fault 2) da overheating na motor 2 armature. Kana sama over voltage relay da motor 1, da kuma PTC thermistor relay da Motor 2, kuma output (Normally open output, changes to close when faulty) na waɗannan relays za a sama across F1 (fault input) da C (common), da F2 (fault input) da C (common) na annunciator system. Saboda haka, idan takarda na motor 1 ya zama mafi yawa, over voltage relay zai yi aiki da kuma zai make closed loop between F1 and Common. Don haka, F1 window zai faru, wanda yana nufin cewa motor 1 yana kasance da over voltage. A baya, annunciator relay zai changeover, da kuma idan kana sama hooter da output contacts, hooter zai faru.

Duk da haka, idan temperature na armature na motor 2 ya zama mafi yawa, PTC thermistor relay zai changeover da kuma zai make loop path between F2 and Common C. Don haka, F2 window zai faru, wanda yana nufin cewa motor 2 yana kasance da overheating. A baya, annunciator relay zai changeover, da kuma hooter da output contacts, zai faru. Baƙin haka, annunciator output relay changeover yana da mata, ba ɗaya ɗaya. An amfani da ɗaya hooter don duka fault windows. Auxiliary AC/DC supply yana bukatar don yi aiki na annunciator, da modern annunciators, akwai window da kuma connection don monitoci auxiliary supply.

Modern Alarm Annunciators suna da power supply unit SMPS, programming unit CPU, da kuma connections including fault contacts da facial display units. Windows da suke faru suna da acrylics, wanda suke enlighten da LED da kuma low power consumption. Typically, annunciation effectively starts from 4 faults that is 4 windows, if the number of faults to be monitored is more than 64, it is preferable to install the programming unit CPU, power supply unit PSU and the display facial unit individually, which ensures the maximum accuracy and effectiveness.
