2 .3 Description of an automatic centralized notification cnsa

2 .3. 1. A centralized notification system of automatization (cnsa) (Figure - 2.3.1).

CNSA designed to alert officials in automated mode and alert the population.

Alert officials in automatic mode by telephone wireline public through the device and automated alerts tion officials ASO-N.

Public notification by using sirens, radio broadcasting nodes (RBN), broadcasting stations and audio in the TV to a wired telephone networks public or private lines running through the device sirens (CCD).

The complex technical tools include:

remote control means notification with software-based PC that runs in wireline networks and is designed to control the means of notification;

device automated alerts officials ASO-N, is intended to alert officials by phone wired network connection, as well as on cell phones cellular communication through a wired network connection;

control unit running sirens (CURS), is designed to manage devices running sirens;

device running sirens CCD three versions, designed to manage the launch of sirens, radio transmission unit (RTI), language radio and record sound channels.

ASO-N produced on 8-64 wireline.

Average time alerts 100 subscribers ASO-8-9 min., ASO-64-1, 5 min.

Set ASO-N and operated by the belly with a belly.

PUZS-N operates on 1 .... 8-lines.

Single channel PUZS-N can run from the first minute. 2.3 sirens. For an increased rate of n ing sirens start to increase the number of lines that connects to PUZS-N.

Set PUZS-N and operated by the belly with a PUZO.

CCD designed:

PZS-1 to control electromechanical sirens;

CCD-2 to control the system loudspeaker Collective Farms-22 may be complementary use Electric playing device which stores formalized language message;

CCD-3 to manage radio broadcasting nodes.

 

2. 3.2 Radio-controlled notification system (rcns)

RCNS intended to alert the population to unrestricted areas.

RCNS a hardware and software system hardware, which allows you to build warning system of any configuration and length. Baseline concentration c tion hardware designed as universal and can use various types of communication at manitni by replacing individual blocks and software. Structural scheme of RCNS of meteorological stations and booster cable broadcasting in n n i (DPM) is indicated in Fig. 2. 3 .2.

RCNS consists of:

- Remote control by means of notification (belly) with several modifications at Dr. lary equipment;

- Device management terminal facilities notification (EFNC) several modifications and this who are subscribers of the respective communication systems and working in unheated areas.

Belly consists of:

- Workstation (WS) based PC with the system and the heat and lnym software;

- Receiving and transmitting device with an antenna and feeder.

EFNC depending on the functions completed the appropriate set of blocks and software, with all modifications presence of a T or cross-charged, power block, power supply, sealed battery capacity of 40 A / g Set blocks with appropriate software and we determined DESIGN solutions to the system.

 

 

 

Figure. 2. 3 .2 - Sovietscontrol warning system

When you created the objects and local warning systems based trunking radio stations can be used standard DTMF or other relevant interfaces and software. This warning system is created without the use of trunked radio base stations. Encompassed and governmental on the area with a radius of 30 km.

When creating a warning system of unlimited length used radio standard MRI-1327 or other relevant interfaces and apps and sham software. This means managing alerts via basic art and ntsiyi trunked radio communications.

Basic design of hardware and software

allow the use of various types of wireless communication (trunking, cellular, satellite) and wired communication system in the complex k ing relevant interfaces and software.

Means with the right software can create favorable condi thou complex environment monitoring system of forecasting developments on potentially hazardous objects.

Modifications EFNC allow you to perform the following functions:

remotely receive coded control signals, turn on and off by the signal sirens, amplifiers, to intercept audio in the mo they radio and television, give answers to belly on the performance (failure) and pr ployed teams;

receive and transmit speech messages are transmitted from the belly;

form automatically coded emergency signals about nesanktsi at Proposed access EFNC, sirens, speakers, power supply failure, ac discharge in mulyatora, disconnect the power supply 220/380 V, 50 Hz;

serve as a warning during the time when disconnected network liv ing at 220/380 V, 50 Hz.

Modifications belly allow you to perform the following functions:

perform remote control EFNC individuals and groups coded signals;

transfer to EFNC linguistic message;

accept EFNC coded signals answers about the commands;

make visualization of terrain maps with plotted EFNC to their subscribers t skymy numbers;

accept EFNC emergency coded signals condition with light reflection at ing and playback alarm sound and display on the area map EFNC who issued alarms;

memorize and log all incoming and outgoing data on upra in laziness EFNC with date, time, month and year of each event;

memorize and log all incoming and outgoing text information transmitted and received between the belly different levels of hierarchy;

make documenting all incoming and outgoing information;

toáreceive data from automated weather stations ISA displaying them on the screen;

when the concentration of ammonia gas in air limit values ​​is a reflection of light and sound reproduction signal from the listed Mr. tion date, time, month and year.

The complex hardware warning system also includes remote switches that allow you to turn on and off the street at high-profile speaker wire broadcasting network.

Benefits RCNS:

Small you turn the sirens on the group management team - not more than 2 seconds. 1 siren getting answers about the command;

for managing all EFNC within range of the base station trunked y and diozv'yazku only need one pair of frequencies;

possibility of building a warning system of unlimited length;

to build a warning system is not necessary laying telephone lines, feeders and building facilities for the end of city;

ability to perform its functions EFNC alerts when disconnected same power and 220/380 V, 50 Hz;

universality of basic design, which allows a set of relevant units and software use various types of communication;
