摘　　要：针对水稻机直播时播种量超限不易察觉的难题,研制了播种监测器。监测器可用键盘进行播种量及播种误差设置,以红外光敏对管作为监视传感器,采用AT89C51单片机对信号进行采集、处理,用显示器实时显示播种量。当播种量超出预设值的范围时,声光报警装置自动报警。监测器具有如下特点:1)监测精度较高,工作可靠;2)可同时监测多播行的播种量,具有可扩展性;3)结构简单,操作方便;4)成本低;5)适用范围广。试验结果表明,各项性能指标均达到了设计要求,实现了水稻直播机播种量的自动监测,为水稻精量直播、增产增收创造了条件。In view of the problem that exceeding the limited seeding quantity is hard to be detected in the use of the rice drill, seeding detector was researched and developed. The detector takes keyboards to set seeding quantity and errors, adopts the infrared photo tube as its detection sensor, employs single-chip microprocessors AT89C51 to collect and process signals and uses display to show the seeding quantity on the spot. When the seeding quantity surpasses the preset number, the sound-light alarming device gives an alarm automatically. The detector bears several characteristics as follows: (1) high precision and reliability; (2) ability to inspect seeding quantity of many rows simultaneously and expansibility; (3) simple structure and convenience; (4) low cost; (5) wide scope of application. The result of experiments shows that all the properties and indexes of the detector have met the expected standards. The detector achieves automatic seeding detection for rice drill, which serves to realize precise direct seeding and improve the production and income.
