摘　　要：为解决超差双翻斗式雨量传感器在检定校准时精细定量调测问题,尤其针对在大小雨强(4 mm/min和1 mm/min)测试时误差值为一正一负,目前只能通过目测观察法并依靠经验对容量调节螺母和定位螺母进行调节,这存在着一定的盲目性并且成功率低;提出了一套检定流程并利用红外光电传感器和步进电机模块,实现了上翻斗和计量翻斗的左右斗的翻动数据的定量测量以及定位螺母和容量调节螺母的自动调节,并且可自动记录和上传检定数据到上位机;结果表明:该系统能有效地判定和解决翻斗翻动平衡和协调性问题,并可为业务人员积累检定数据,以便后续分析处理。In order to solve the problem of fine and quantitative adjustment in the verification and calibration of the output by double tipping bucket rain sensor,especially for the fact that the measurement error is positive or negative under the conditions of large or small rain intensity(4 mm/min or 1 mm/min),at present,the capacity adjusting nut and positioning nut can only be adjusted by the visual observation and experience,which has certain blindness and low success rate.A set of verification process is proposed,and the infrared photoelectric sensor and stepping motor module are used to realize the quantitative measurement of the turnover data of the left and right buckets of upper tipping bucket and metering tipping bucket,as well as the automatic adjustment of the positioning nut and capacity adjusting nut,and the verification data can automatically be recorded and uploaded to the upper computer.The results show that the system can effectively determine and solve the problems of tipping balance and coordination,and the verification data is accumulated,analyzed and processed for the business personnel later.
