head positioning time 中文意思是什麼
head positioning time
解釋
磁頭定位時間-
By using high - speed data acquisitioning unit designed specially to capture travelling waves of transient current, using global positioning system ( gps ) to supply high precise time tagging for both ends, using wavelet transform theories to identify the head of the travelling waves, the fault locator can realize high precise double - ended travelling waves location
該測距裝置採用專門設計的高速采樣單元捕獲暫態電流行波信號,用全球定位系統( gps )為線路兩端提供精度高達1 s的統一時標,用小波變換理論識別暫態電流行波波頭信息,從而可以實現高精度的雙端行波法測距( 150m ) 。
