摘　　要：为了精准量测典型田块作物的灌溉水量,需要设置计量设施,但由于末级渠道现场条件复杂,典型田块可能存在边界不清、形状不规则、与灌区面积不协调,以及种植作物、进水口不够单一等情况,即便选出了典型田块,但由于多为U形渠道,也不便于在末级渠道设置简易量水槛或采用标准断面量水。基于此,本文提出了一种在现场条件复杂的情况下在典型田块设置的超声波水表智能量测系统,该系统结构简单、便于维护,量测效果良好,适合复杂条件下的田间作物的灌溉用水计量。In order to accurately measure the irrigation water consumption of crops in typical plots, metering facilities need to be set up. However, due to the complex field conditions of the final channel, typical plots may have problems such as unclear boundaries, irregular shapes, incompatibility with the irrigation area, various planting crops and water intakes, etc. Even if typical plots are selected, they are mostly U-shaped channels which is not convenient to set up a simple water sill in the final channel or use standard section to measure water. On this basis, this paper proposes an intelligent measuring system of ultrasonic water meter set in typical field under complex field conditions. The system is simple in structure, easy to maintain and good in measuring effect, which is suitable for the irrigation water measurement of crops in the field under complex conditions.
