SUGAHARA S-0000 REV.C

主要由系統(tǒng)內(nèi)部元器件及電路間的相互電磁輻射產(chǎn)生，如邏輯電路互輻射及其對(duì)模擬電路的影響，模擬地與邏輯地的相互影響及元器件間的相互不匹配使用等。這都屬于SUGAHARA S-0000 REV.C制造廠對(duì)系統(tǒng)內(nèi)部進(jìn)行電磁兼容設(shè)計(jì)的內(nèi)容，比較復(fù)雜，作為應(yīng)用部門是無法改變，可不必過多考慮，但要選擇具有較多應(yīng)用實(shí)績或經(jīng)過考驗(yàn)的系統(tǒng)。

怎樣才能更好、更簡(jiǎn)單解決SUGAHARA S-0000 REV.C系統(tǒng)干擾？
1）選用隔離性能較好的設(shè)備、選用優(yōu)良的電源，動(dòng)力線和信號(hào)線走線要更加合理等等，也能解決干擾，但是比較煩瑣、不易操作而且成本較高。
2）利用信號(hào)隔離器這種產(chǎn)品解決干擾問題。只要在有干擾的地方，輸入端和輸出端中間加上這種產(chǎn)品，就可有效解決干擾問題。

In this application, the sensor nodes operate compleby passively and do not carry batteries, for the sake of long-term measurement and higher maintainability.Upon data collection, an external mobile element provides energy to each node via microwave transmission, wakes it up,SUGAHARA S-0000 REV.Cand collects data from it. The prototype system uses a radio-controlled helicopter as the mobile element that is either remobypiloted or GPS-programmed. Each sensor node is equipped with ATmega128L microcontroller, a 2.4GHz XBee radio, antennas for transmission/reception, and a supercapacitor to store the energy. Each node has two types of sensors. One is a piezoelectric sensing element integrated with nuts and washers to check if the bolt has loosened. The other is capacitive-based sensors for measuring peak displacement and bolt preload. Since the size of data from these sensors are small,communication time is almost negligible; however, it takes a few minutes to charge a supercapacitor through microwave transmission in the current prototype. 

The team is currently investigating a new design to improve the charging time down to tens of seconds.The data collected by the UAV is brought back to the base station and analyzed by researchers using statistical techniques for damage existence and its b/type. Since SUGAHARA S-0000 REV.C  primary purpose of this application is to assess the safety of large civil structures after a disaster such as an earthquake, every process including data collection and analysis needs to be as quick as possible for b recovery. Furthermore, shorter travel time is required in view of the limited fuel on the helicopter
