摘要:3DJY-45型烟苗剪叶机实现了剪叶和消毒的自动化控制,但是当系统出现问题时,无法迅速报警并确定故障点,为了保证设备高效稳定的工作,设计了基于STC89C52RC单片机控制的剪叶机监控系统。试验结果表明,系统报警成功率高于95%,当系统出现故障时,监控系统能及时发出声音报警同时确定故障点,并将故障点显示在人机交互界面,为故障维修提供了依据,提高了维修效率。

Abstract: Automatic leaf-cutting and disinfecting were achieved in the 3DJY-45-tobacco seedlings leaf-cutting machine, however its difficult for the machine to alarm and locate points of fault when failures occurred, so a STC89C52RC-based leaf-cutting monitoring system was designed to make up for the lack of alarming and fault points locating. Results showed that, the alarm success rate of system was above 95%, when the system had the breakdown, the monitoring system could give the sound alarm in time and determine the fault, and then the points of fault will be displayed on the human-machine interaction, which gave basis to maintenance, improved the maintenance efficiency as well.

目前漂浮育苗作为工厂化育苗的一种方式,凭借其育苗效率高、能有效预防幼苗病害、移栽过程简单、返苗速度快等优点,广泛应用于烟草育苗行业。为了培育根系健壮的烟苗,在育苗过程中要适时对烟苗进行剪叶。
3DJY-45型烟苗剪叶机主要由剪叶机构和消毒机构组成。剪叶机构的主要任务是根据苗床的大小,调节剪叶范围并选择剪叶路径,实现了苗盘无需离开苗床的剪叶功能;消毒机构的主要任务是控制剪叶过程中的消毒频率和消毒量。虽然该设备实现了剪叶和消毒的自动化控制,但是当系统出现问题时无法迅速报警并确定故障点,例如当消毒管堵塞时,剪叶机构仍能正常工作,但消毒机构无法对刀具进行消毒,不能有效防止病菌的传播,影响系统工作的可靠性。为了保证设备高效稳定的工作,设计了剪叶机监控系统,当系统出现故障时,监控系统能及时报警并确定故障点,将故障点显示在人机交互界面上,提高了维修效率。……
