  1. To our satisfaction, all the measuring results from the measurement locale are accurate and convincing comppared with the results calculated by the theory which makes it clear that the system can meet the demands of measuring upon the dafosi bridge of changjiang river. the system has achieved the long - time and real - time automatic deflection measurement of the bridge at first time in our country, and the system has passed the appraisal of the experts consigned by the ministry of communications so the system has the practical value on the long - span bridge ' s deflection measurement

    通過對橋梁實際測量結果與理論計算的結果的對比分析可知，本文所設計的連通管式光電撓度測量系統測量數據準確，系統可靠，能夠滿足大佛寺長江大橋撓度測量的需要。該撓度測量系統首次在國內實現了橋梁主梁撓度的長期實時自動監測，並且已經通過了交通部的項目驗收，具有一定的推廣價值
  2. The measurement of deflection of a bridge is crucial constituent part in the monitoring of bridges. the majority of existing methods about bridge deflection measurement can not accomplish the real - time and long - range measurement. the ultrasonic method based on connected pipes still has shortage in precision and speed of measurement. to satify the need of deflection measurement of the dafosi bridge of changjiang river, an opto - electronic measurement method is to be used to improve on the method based on connected pipes. furthermore, we will design an automatic opto - electronic deflection measurement system based on connected pipes which can be practised in the long - span bridge

    大型橋梁的安全監測具有重要的現實意義，而撓度監測是橋梁監測的一個重要的組成部分。目前現有的許多撓度測量方法還不能實現實時遠程監測，已有的連通管式超聲波法還存在著精度較低，測速慢等不足。針對大佛寺長江大橋撓度測量的需要，在此採用精度較高的光電測量方法結合連通管的優點加以改進。
  3. Measurement test the speed with untouchable measurement, touchable measurement and all kinds of measurement speed sensor have been analyzed from economy, environment, precision, life - span, etc. compari ng relevant error that the measuring system produces at the same time, to examine combined harvester complete machine request of performance of producing. make relevant error meet the precision request, and can reach the best state

    對接觸性測量和非接觸性測量兩類測速方法及各類測量速度傳感器從經濟、環境、精度、壽命等方面進行了分析，同時對測量系統所產生的相關誤差進行比較，針對測產型聯合收割機整機性能的要求，使相關誤差滿足其精度要求，並且能夠達到最佳狀態。
