摘要： 본 고안은 퍼블릭어드레스 파워앰프의 점검부 전면배치 구조에 관한 것으로, 퍼블릭어드레스 파워앰프에 있어서, 입력신호를 점검하기 위한 입력신호 단자부와, 직류 및 교류 전원의 공급상태를 점검하기 위한 전원단자부와, 출력신호의 상태를 점검하기 위한 출력신호 단자부를 장치의 전면부에 배치하는 구조를 구현함으로써, 각 신호 및 전원의 공급상태를 점검하는데 소요되는 시간을 단축하고, 점검도중에 발생되는 장비의 가동 방해 요소를 제거하며, 장비의 특성을 즉시에 점검할 수 있는 상태로 유지할 수 있는 효과를 갖는다.

摘要： A removable communication module for a PA power amplifier applying a front type self diagnosis system is provided to perform independent inspection without an additional monitor and a control computer by applying a stand-alone self diagnosis system. An overheat diagnostic part(102) judges the overheating warning inside the amplifier inside. A cooling system diagnostic part(104) judges the inspection warning of the cooling system. An emergency diagnostic part(106) judges lowering and nonexistence of the emergency power. An emergency power source fuse diagnostic part determines whether the line of the emergency power fuse is connected or not. A commercial power diagnostic part(110) judges the lowering of the commercial voltage. A commercial power fuse diagnostic part(112) determines whether the line of the commercial power fuse is connected or not. A removable communication module(2) receives a control signal and transmits a logic level or data to the outside. The removable communication module is composed of a control output unit(300), a first serial communication unit(302), and a second serial communication unit(304) and an address control switch(306).

摘要： The present invention relates to an abnormal load analysis processing method for public address broadcasting and an apparatus thereof. The abnormal load analysis processing method, in which an abnormal load analysis of a loud speaker including an electrical wiring connected to an output of a public address broadcasting device amplifier is analyzed and processed, includes: comparing and analyzing an initial individual load value when an abnormal analysis is performed and a real-time individual load value during usage for each individual loud speaker; and electrically separating only the loud speaker load including the electrical wiring corresponding to a short wire from the public address broadcasting device amplifier. (Here, the initial individual load value is characterized as an initial 2 same rate value, and the initial 2 same rate value is a value of an initial load voltage value divided by an initial load current value; and the real-time individual load value is characterized as a real-time 2 same rate value, and the real-time 2 same rate value is a value of a real-time load voltage value divided by a real-time load current value). According to the present invention, even when an abnormality occurs in unspecified multiple load sides, only the abnormal loads are electrically separated from the public address broadcasting device amplifier or marked and corrected, so that a normal broadcast transmission and an emergency escape broadcast can be prevented from being interrupted in all of the normal load loud speakers to relieve public inconvenience, satisfy fire safety criteria of emergency broadcast equipment, and additionally, material consumption of an output amplifier can be reduced and damage of the amplifier can be prevented when building the public broadcast device.
