    摘要:

    基于STC12C5A60S2單片機，采用串口通信技術,、數(shù)據(jù)庫技術,、VS2008軟件編程技術，設計并實現(xiàn)了施藥監(jiān)測系統(tǒng),。該系統(tǒng)具有可擴展性,，可支持8路模擬傳感器和2路數(shù)字脈沖式傳感器,，以采集壓力,、流量和速度等各種施藥參量,，并通過LCD顯示器實時顯示；系統(tǒng)可將各施藥參量存入SD卡中,，同時通過RS232串口傳給PC機,；PC機將接收到的數(shù)據(jù)存儲于數(shù)據(jù)庫中，并以表格和圖形方式向用戶顯示施藥參量,。試驗表明：采樣周期為1s時,，速度經(jīng)一次校核后測量平均精度達97.7%；測試平臺試驗和噴藥機試驗的壓力測量平均精度分別為99.3%和98.7%,，流量平均測量精度達99.3%,。

    Abstract:

    A pesticide application monitoring system was designed by using serial communication technology, database technology and VS2008 software programming technology based on MCU STC12C5A60S2. The system could collect information from eight analog sensors and two pulse sensors at the same time. The pesticide application parameter data from sensors (pressure sensor, flow sensor, speed sensor, etc.) would be displayed on LCD monitor, stored in SD card and transmitted to PC through RS232 serial port. Then the data will be stored into database and showed to users in the term of tables and graphs on PC as well. Experiments showed that while the sampling period was 1s, the average measuring accuracy of speed was 97.7% after the system calibration, the average measuring accuracy of pressure in “test-bed experiment” and “sprayer experiment” was 99.3% and 98.7%, and the average measuring accuracy of flow was 99.3%.
