基于LabVIEW的玉米果穗立式烘干仓监测系统的设计

Design of monitoring system for the vertical drying bin of corn fruit ears based on LabVIEW

利用研华ADAM4000系列数据采集模块,在LabVIEW平台上开发出玉米果穗立式烘干仓监测系统。该系统是由主控、信号通道、文件操作、数字滤波、频谱分析、统计分析、系统监测等模块组成,当烘干过程中的种子接触的温度的数值除以10的值大于等于监测阈值4.3时,系统就实时完成报警,实现了温度、压力数据的采集、处理和监测。应用情况表明果穗接触温度在256.41K和484.71K之间变化,能达到玉米种子果穗烘干的安全要求,证明该监测系统有效的提高了果穗干燥的安全性。

Using the series data acquisition module of ADAM 4000 ,developed the monitoring system for the vertical drying bin of corn fruit ears by the LabVIEW platform ..This system consisted by the modules of main control ,signal channel ,file operation ,digital filter ,frequency spectrum analysis statistical analysis and systematic monitoring and so on .During the drying process ,when the value of the temperature contracting by the drying seeds divided 10 was greater than or equal to the threshold value 4 .3 ,this system can be real-time alarm ,to realize the data acquisition for the temperature and pressure ,treatment and monitoring .The application showed that ：The temperature contacted by the corn fruit ears was changing between 256 .41 K and 484 .71 K ,it can be met the safety drying requirements for the corn seed fruit ears .It was proved that this monitoring system can be effectively improving the drying security for the fruit ears .
