基于PLC的烟尘浓度自动监测装置设计

Design of an Automatic Monitoring Device for Soot Concentration Based on PLC

针对烟尘监测装置存在体积大、价格高、效率低的问题,本文设计一种基于PLC的烟尘浓度自动监测装置,该装置采用称重法为主、激光法测量为辅的策略实现现场烟尘测量,实时采集并处理数据,同时采用WINCC上位机实现监控。实证表明:本装置能够对烟尘浓度进行自动监测,对促进改善空气质量具有一定指导意义。

Aiming at some problems such as large volume,expensive price and low efficiency,this paper put forward an automatic device for soot concentration monitoring based on PLC.The device adopted the principal weighing method and laser method as a subsidary to measure soot in the field and real-time data were collected and processed to be monitored by the WINCC host computer.The field application showed that the device could be able to automatically monitor soot concentration and there was a certain guiding significance for improving an air quality.
