摘要
随着社会科学技术发展,越来越多的产业开始实现自动化。近年来,互联网实时监控日渐普及,得到了广泛应用,本文设计了一套基于51单片机的粮仓温湿度检测系统。该粮仓管理系统根据用户所期待的温湿度对环境(粮仓)进行检测,将数据通过2.4G无线网络上传并记录在数据库,并在超出阈值时报警。
For the large range of temperature f luctuations and pushing tube speed and temperature control matching problems, the heating system and hydraulic in the intermediate frequency bender are analyzed, transfer function of heating system and hydraulic system are established. A double closed loop controller is developed and variable integral PID method is adopted in hydraulic system control strategy. The results show that base on a double closed loop and variable integral PID control method ensures accurately control to the temperature and high-level quality to the elbows.
