摘要
针对当前孢子捕捉器普遍存在工作效率低、孢子识别率差、费时费力等缺点,设计了一种以脉冲信号为控制信号,具有高放大倍数、高分辨率的智能农作物病原菌孢子捕捉系统。该系统基于嵌入式工控机、高倍显微镜、电荷耦合器件(CCD)数字摄像头和云服务器等。与传统孢子捕捉器相比,智能孢子捕捉系统能够实现从载玻片加载、病原菌孢子捕捉、显微成像、已使用载玻片回收和监测信息发送至远程监测平台等过程的全自动化,提高了检测精度与工作效率。为了验证系统的性能,于2017年6月与2017年11月期间,对系统进行测试。测试结果表明:该系统不仅具有自动捕捉病原菌孢子的特点,而且能够与病害发生指数数据库进行比对,实现了对农作物病害的远程自动化监测。
Aiming at the shortcomings of current spore traps, such as low work efficiency, poor spore identification rate, time-consuming and laborious, an intelligent crop pathogen spore capture system with high magnification and high resolution with pulse signal as control signal is designed. The system is based on embedded industrial computer, high power microscope, charge coupled device(CCD) digital camera and cloud server. Compared with traditional spore trap, intelligent spore trapping system enables full automation from slide loading, pathogen spore capture, microscopic imaging, used slide recovery and monitoring information sent to remote monitoring platforms, improves detection accuracy and work efficiency.In order to verify the performance of the system, during the period of June 2016 and November 2017, the system was tested. The test results show that the system not only has the characteristics of automatically capturing the spores of pathogenic bacteria, but also can be compared with the database of disease occurrence indexes, thereby realizing remote automatic monitoring of crop diseases.
