Summary:An objective of the present invention is to provide a wireless damper controller for smoke control of a building which can adjust internal pressure balancing. The wireless damper controller for smoke control of a building is used in a wireless building smoke control system including a front room smoke control device and a living room smoke control device transceiving signals via wireless communication, and linking front room smoke control and living room smoke control to each other to perform building smoke control. The wireless damper controller for smoke control of a building comprises: a main body; an absolute pressure sensor attached to and detached from the main body, and measuring the pressure of a living room or a front room; a wireless communication module which is a TX/TX module capable of bidirectional communication; a control device comparing a measured pressure value of an installation point received from the absolute pressure sensor and a measured pressure value of a different point received through the wireless communication module to calculate differential pressure, and considering the measured pressure value of the installation point, the calculated differential pressure, and external state received through the wireless communication module to operate a relay for air blower/damper operation; and a setting switch setting to a main mode if installed on an air blower introducing the outdoor air into a building or discharging the indoor air in the building to the outside, and setting to a sub mode if installed on a damper opening and closing a flow path of the air. If the wireless damper controller operates in the main mode, a signal for controlling an air blower speed is outputted. If the wireless damper controller operates in the sub mode, a signal for adjusting the opening degree of the damper is outputted. The external state includes a state whether a fire occurs and a state whether the excessive differential pressure is generated. 건물 제연용 무선식 댐퍼 컨트롤러는, 무선 통신을 통해 신호를 송수신하는 전실 제연 장치 및 거실 제연 장치를 포함하고, 전실 제연 및 거실 제연이 상호 연동되도록 하여 건물 제연을 수행하는 건물 무선 제연 시스템에 사용되는 건물 제연용 무선식 댐퍼 컨트롤러로서, 건물 제연용 무선식 댐퍼 컨트롤러는, 본체, 본체에 탈착되며, 거실 또는 전실의 압력을 측정하는 절대압력 센서, 양방향 통신이 가능한 TX/RX 모듈인 무선통신모듈, 절대압력 센서로부터 제공받은 설치 지점의 측정 압력값과 무선통신모듈을 통해 수신한 타 지점의 측정 압력값을 비교하여 차압을 산출하고, 설치 지점의 측정 압력값, 산출된 차압 및 무선통신모듈을 통해 수신된 외부 상태를 고려하여 송풍기/댐퍼 조작용 릴레이를 작동시키는 제어 장치, 및 외기를 건물 내로 유입시키거나 건물 내의 내기를 외부로 배출시키는 송풍기에 설치될 경우 메인 모드로 설정하고, 공기의 유로를 개폐하는 댐퍼에 설치될 경우 서브 모드로 설정하는 설정 스위치를 포함하고, 메인 모드로 작동할 경우, 송풍기 속도를 제어할 수 있는 신호를 출력하고, 서브 모드로 작동할 경우, 댐퍼의 개도를 조정할 수 있는 신호를 출력하고, 외부 상태는 화재 발생 여부 및 과도 차압 발생 여부를 포함하는 것이다.
