Abstract

본 발명은 방사능이나 가스 누출 또는 외부인의 침입이 가능한 여러곳에 설치되어 해당 지역별로 누출되는 방사능(가스량)등을 검출하고 그에 따른 적절한 제어를 수행하는 다수개의 지역감시장치와 중앙에서 다수개의 지역감시장치를 통괄 제어하는 중앙통제부간에 송수신되는 검출된 가스량및 시스템 체크 데이타를 유ㆍ무선으로 송수신할 수 있는 환경감시용 유ㆍ무선 종합방재 시스템에 관한 것이다.The present invention is installed in a number of places where radiation or gas leakage or outsider invasion is possible, a plurality of regional monitoring devices and a plurality of regional monitoring devices in the center to detect the radiation (gas amount) leaked for each region and perform appropriate control accordingly The present invention relates to a wired / wireless comprehensive disaster prevention system for environmental monitoring that can transmit and receive detected gas volume and system check data transmitted and received between the central control unit that controls and controls the system.

이러한 본 발명은, 가스누출 또는 기타 여러가지 형태의 방재가 예상되는 지역에 설치되어 누출되는 특정가스량등을 감지하는 센서와; 센서에서 검출된 특정 가스의 량 또는 외부 침입자의 위치가 설정된 범위를 초과할 때 가스의 공급 또는 출입문을 차단하기 위한 차단부와; 소정의 센서 및 차단부와 접속되어 제어를 수행하거나 각종 데이타를 송수신하는 소정수의 지역제어부; 소정수의 지역제어부를 총괄 제어하면서 각 지역제어부에서 송신하는 각종 데이타를 집계ㆍ분석ㆍ출력ㆍ저장하는 중앙통제부와; 중앙통제부와 지역제어부 간에 유ㆍ무선으로 데이타 송수신이 이루어지도록 같은 속도 또는 주파수대역을 갖는 한쌍의 유/무선송수신장치로 이루어진 소정수의 모뎀을 구비하여, 지역 감시장치와 중앙통재부간에 전용선 또는 일반 공중망을 이용 무선으로 신호를 송수신하므로써, 시스템 설치가 한결 쉬워지고 많은 양의 전선을 소모하던 종래와는 달리 경비가 절감됨은 물론 나아가 양방향 확인과 자료수집, 분석을 통한 제어로서 안정성과 정확성에 큰 장점을 나타내게 되는 것이다.The present invention, the sensor is installed in the area where gas leakage or other various types of disaster prevention is expected to detect a specific gas amount leaking; A blocking unit for blocking the supply of gas or the door when the amount of the specific gas detected by the sensor or the position of the external intruder exceeds a set range; A predetermined number of local controllers connected to predetermined sensors and blocking units to perform control or to transmit and receive various data; A central control unit which aggregates, analyzes, outputs, and stores various data transmitted from each local control unit while collectively controlling a predetermined number of local control units; It is equipped with a predetermined number of modems consisting of a pair of wired / wireless transmission and reception devices having the same speed or frequency band so that data can be transmitted and received between the central control unit and the local control unit by wire or wireless. By transmitting and receiving signals wirelessly using a public network, the system is easier to install and the cost is reduced, unlike the conventional method, which consumes a large amount of wires. It will show its advantages.
