This dissertation describes the studying of the whole construction of water - saving irrigation expert control system, the realization of hardware and software and low - cost soil - moisture sensor which is needed for water - saving irrigation. the distributed control system based on bus. according to real - time data of soil - moisture, water - level of sump, pressure of tube, etc. and irrigation knowledge in expert knowledge bases, it can make decisions such as when to irrigation, the water quantity to irrigation and the cost and benefit of the irrigation
本文對節水灌溉專家控制系統的總體結構、軟硬體實現以及節水灌溉急需的低成本土壤水分傳感器進行了研究,系統採用了基於總線的分散式控制結構,根據實時檢測的土壤水分、水槽水位、管道壓力等實時參數,知識庫的作物灌溉知識,分析決策灌水時間、灌水量、灌溉成本及灌溉效益。The product has filled in the gaps in china and won the " excellent new product " prize of state. it squality comes up to the same cylene brilliant blue 6b level of sandoz co. of swizerland and the color surpassed the cylene 6b, the annual output is 200 tons
該產品填補了國內空白,榮獲國家級優秀新產獎,產品質量經沈陽化工研究院檢測,產品質量達到瑞士山道士公司同類產品柴林艷藍6b水平,色光優于柴林艷藍6b ,年生產能力200噸。On the basis of research results of the existing experts and scholars especially the theory put forward by professor xu zhenliang ( my tutor ) that predicts the velocity profiles and friction loss of settling slurry when it flows in horizontal pipe and upward - inclined - pipe, relations among the velocity of water, that of solid particles and that of settling slurry have been established by the analysis of momentum transmission process between water and solid. then the calculation formulae for fricton loss of downward inclined and vertical pipe are deprived
本文在現有專家學者的研究成果特別是許振良教授(導師)提出的預測非均質流在水平管道及向上傾斜管道流動時的速度分佈及摩阻損失的理論的基礎上,從動量守恆的角度建立了清水速度、固體顆粒速度和漿體速度之間的關系,進而推導出了向下傾斜及垂直管道沉降性漿體輸送的摩阻損失的計算公式。Through redesigning of pipe system to alter its character and using the ways to isolate vibration and reduce vibration, it is yielded very good results of reducing the vibration and noise. in some points the acoustic pressure level drops very much, such as in the standard point of number one pump the acoustic pressure level drops 15db ( a ) and in the standard point of cistern also drops 15db ( a ), and in the highest point of the acoustic pressure before redesign drops from 105db ( a ) to 44db ( a ), and in the second floor the acoustic pressure level have reached the requirment
通過對管道結構的改造,減振和隔振措施的有效使用,使供水系統的振動和噪聲得到了有效的控制:使一號泵前的標準點和蓄水池前標準點的噪聲聲壓級都降低了15db ( a ) ,管道上測點的振動量降低了90 ;二樓居民門外的噪聲從55db ( a )降到25db ( a ) ,遠低國家標準35db ( a ) ;在改造前噪聲最大點西側蓄水池的噪聲也由105db ( a )降到44db ( a ) 。分享友人
