气吸式播种机质量监控系统设计——基于ZigBee无线传感网络

针对气吸式播种机常出现的漏播和重播现象,在ZigBee技术和单片机的基础上提出了一种新的气吸式免耕播种机的质量监控系统,并对播种机的核心部件排种器进行了结构优化设计,制造了试验样机。播种质量监测系统以STC89C51单片机和ZigBee无线模块为主要部件,结合红外线传感器和涡流位移传感器对漏播和重播数据进行采集,实现了振动台的自动化控制和远程报警功能,以及LCD12864液晶对监测参数的实时显示。通过对播种机的大量测试,得到了不同播种机行进速度的排种质量曲线,由测试结果可以看出:排种质量监测系统可以成功地对漏播率和重播率进行监测,且遗漏监测的次数很少,排种和漏播播种率的精度较高,达到了精密播种机的设计标准。

Design of Quality Monitoring System for Pneumatic Seeding Machine Based on ZigBee Wireless Sensor Network

Since the air suction seeding machine often appears leakage sowing and replay phenomenon , it proposed a new gas suction type quality monitoring system of no tillage seeder based on ZigBee technology .And the drill core components of the metering device on the line structure with optimization design , it has done manufacturing the prototype experiment . The quality monitoring system combined with infrared sensor and eddy current displacement sensor to collect the data of the leakage and replay , realized the automatic control and remote alarm function of the shaking table based on STC 89 C51 microcontroller and ZigBee wireless module as the main components .And it realized the real-time display of LCD12864 liquid crystal .Through a lot of testing of the seeding machine , the quality of the different seeding rate is obtained .From the test results ,it can be seen that the monitoring system can successfully monitor the leakage rate and replay rate .
