中文摘要 | 本研究係利用紅外線感測裝置檢測有無種子通過導管,並以微動開關檢測有無土壤堵塞,以完成單行缺播預警系統。除了先進行室內試驗以確定其準確性外,同時將本系統安裝於國產雜糧播種機上,播種玉米進行田間試驗,測定其可行性及缺失。其主要技術內容係採用價廉之紅外線發光二極體及微動開關,配合單晶片微電腦之軟體技術所組成。其整體結構相當簡易且成本亦甚低。實驗結果顯示,作業速度在每小時5~6公里,偵測時間設定在0.75秒時,其有效感應預警之缺播間隔為4株,失誤率平均為4.4%,可符合實際之作業需求;而微動開關之精確度幾達百分之百,可允許0.51秒內土壤暫時阻塞之發生。 |
英文摘要 | A single-line early-warning system is presented for the detection of the failure-seeding. The system combines an infrared sensor to monitor the seed passing through the seed duct and a moicroswitch to monitor the soil block at the duct end, which is controlled by the single chip software. The system is of simple structure and low cost. The performance of the sytem shows excellent results both in the tests at laboratory and field operations using a domestic planter. The missing rate of detecting failure-seeding of infrared sensor is only about 4.4% when operating at 5-6 km/hr and in the sensor period of 0.75 seconds; that is, the effective sensing-steps for failure-seeding are four. This also shows that the accuracy of the micro-switch reaches nearly 100% and which allows up to 0.51 seconds for the temporary soil blocking at the duct end. |
