產品說明 : Palert is an earthquake P wave alarm with advanced technology. It is embedded Pd technology
developed by Prof. Yih-Min Wu from National Taiwan University (Please refer to the related documents
which Prof. Wu has been published). Designed to reduce earthquake damage, Palert can issue an alarm
within 3 seconds after P wave is detected whether the following shock wave is devastating or not.

Palert offers four kinds of trigger algorithms: Pd, PGA, Displacement and STA/LTA for detecting
earthquakes. Pd algorithm was developed by Prof. Wu as it was mentioned above. PGA stands for Peak
Ground Acceleration. Palert offers 10 Hz and 20 Hz low pass filter which are selected by users to filter
out high frequency components in signal generated by non-earthquake vibration. Component “a” is
especially equipped with real time displacement calculation which is able to deploy displacement trigger
algorithm in “a” axis. The conventional STA/LTA trig algorithm is available on Palert, too.

Intensity standards of both CWB (Central Weather Bureau, Taiwan) and China (GB/T-17742-2008) are
also available and can be shown instantaneously. Other useful earthquake information is stored and
ready for retrieving on Palert. These include trigger time, maximum intensity, maximum acceleration for
each component and maximum acceleration in vector. The powerful networking capability features
streaming real time data to hosts; automatically connects up to 2 servers and NTP (Network Time
Protocol) time calibration. With these networking functions, Palert is a wonderful front end device for
EEW (Earthquake Early Warning) system.

With PC utility, it is possible to record earthquake data for research purposes and to have voice
warnings if needed. Providing two outputs and supporting industrial communication standard Modbus
TCP/RTU, Palert is an ideal product for earthquake safety control in numerous applications.

Palert 為一先進之地震P 波警報器,其除了具備傳統電子式地震開關之功能外,更內嵌由台灣
大學吳逸民教授所開發之地震測報技術,可偵測P 波並在3 秒內決定是否災害性地震來襲,並
在具破壞力之S 波到達前發出警報訊息,以提供使用者做為地震減災之用。

地震判別技術是本機之主要特點,總共提供四種機制來判斷地震,分別是Pd、PGA、
Displacement 與STA/LTA,有關Pd 之地震判別機制為台灣大學吳逸民教授所創, PGA 為Peak
Ground Acceleration 之縮寫,本機備有10Hz 與20Hz 兩種低通濾波可供選擇,以濾除非地震
之高頻訊號;Palert 也特別針對a 軸向(裝置固定時為垂直向)做即時位移處理,故可針對垂直向
之位移(Displacement)來做地震判別;而STA/LTA (STA 短週期加速度平均值 / LTA 長週期加速
度平均值)傳統地震儀之地震判斷邏輯本機亦支援。

可即時顯示中央氣象局(台灣)頒佈之七級地震震度或大陸地震烈度標準,地震之發生時間、最大
震度、三軸合成向量加速度、瞬時三軸向最大加速度等;另可依據使用者之設定來分級驅動內
建DO,以作為直接連動外界設備之界面,例如與電梯連接使其可停靠於最近之樓層;切斷瓦斯
或電熱設備等,以降低地震二次災害。

Palert 內建即時時鐘(RTC)並提供NTP 網路校時功能,可自動串流輸出資料到二部伺服主機以
作為地震速報EEW 之端末機;可即時顯示中央氣象局(台灣)頒佈之七級地震震度,或中國大陸
GB/T-17742-2008 地震烈度,並可記錄最近一筆地震事件之正確發生時間、地震之最大震度、
三軸合成向量加速度、瞬時三軸向最大加速度等;另透過PC Utility 可記錄地震波形與提供地震
語音警示。
