针对气吸式播种机常出现的漏播现象，在单片机和NRF24 L01技术的基础上设计了一种气吸式免耕播种机工作情况监测的装置。该装置以STC89C52单片机和NRF24L01无线模块为主要部件，结合光电对管（接收管为光敏三极管）和超声波传感器，对播种机作业过程中种子的漏播、肥料漏施进行及时的声光报警，并通过LCD12864液晶对所需参数进行实时的显示。试验结果表明，该装置能够稳定、可靠地完成播种机作业时的监测任务监测漏播的准确率可控制在97．2％。

For the missing seed which always occurs to the air-suction seeder ,a monitoringsystem for a kind of suction and no-till planter is designed in the paper based on single-chip and NRF24 L01 .With STC89 C52 microcontroller and NRF24 L01 wireless module as main parts , the system monitors the working parameter of suction seeder byinfrared tube ( infrared phototriode as receiving tube ) and Ultrasonic sensor .The seeding absence alarm and working parameter can be passed with wireless module communicate withsingle-chip,then microcontroller use LCD module and alarm devise to show and warn .The test results show that the decice can complete the monitoring task stably and seed leakage alarm accuracy can be controlled at 97 .2%.
