    摘要:

    為解決超差雙翻斗式雨量傳感器在檢定校準時(shí)精細定量調測問(wèn)題,尤其針對:在大小雨強(4mm/min和1mm/min)測試時(shí)超差值為一正一負,目前只能通過(guò)目測觀(guān)察法并依靠經(jīng)驗對容量調節螺母和定位螺母進(jìn)行調節,這存在著(zhù)一定的盲目性并且成功率低。提出了一套檢定流程并利用紅外光電傳感器和步進(jìn)電機模塊,實(shí)現了上翻斗和計量翻斗的左右斗的翻動(dòng)數據的定量測量以及定位螺母和容量調節螺母的自動(dòng)調節,并且可自動(dòng)記錄和上傳檢定數據到上位機。結果表明:本系統能有效地判定和解決翻斗翻動(dòng)平衡和協(xié)調性問(wèn)題,并可為業(yè)務(wù)人員積累檢定數據以便后續分析處理。

    Abstract:

    In order to solve the problem of fine and quantitative adjustment in the verification and calibration of the out of tolerance double tipping bucket rain sensor, especially for the fact that the error value is one positive and one negative in the test of large and small rain intensity (4mm / min and 1mm / min), at present, the capacity adjusting nut and positioning nut can only be adjusted by visual observation and experience, which has certain blindness and low success rate. A set of verification process is proposed, and uses infrared photoelectric sensor and stepping motor module to realize the quantitative measurement of the turnover data of the upper tipping bucket and the left and right buckets of the metering tipping bucket, as well as the automatic adjustment of the positioning nut and capacity adjusting nut, and can automatically record and upload the verification data to the upper computer. The results show that the system can effectively determine and solve the problems of tipping balance and coordination, and accumulate verification data for business personnel for subsequent analysis and processing.
