摘要
根据目前粮情管控系统中粮仓温湿度测量存在的问题,设计出一种基于现场总线分布式的粮情管控系统粮仓温湿度测量电路。利用单总线数字技术,接口电路及调整电路,并采用组态王6.53软件进行仿真试验。试验结果表明,该温湿度测量电路能使基于现场总线分布式粮情管控系统成本降低、测量精度提高、抗干扰性能增强、线路简单、安装维护方便等优点,满足了实时测控和管理的要求。
According to the present granary measuring and controlling system,a fieldbus distributed control system granary temperature and humidity measuring circuit was designed.Using the single-bus digital technology,interface and adjusting circuits,simulation experiments were done by kingview 6.53.The simulation results showed that the temperature and humidity measuring circuit had the advantages of cost reduction,improved accuracy,en-hanced anti-jamming performance,easy installation and maintenance,and it could fulfill real-time measuring and controlling requirement.
