基于西门子PLC除尘器粉尘防爆危险源信号检测及预警系统的研究

Research on Dust Explosion-proof Hazard Signal Detection and Early Warning System Based on Siemens PLC

研发适用于滤袋式除尘器粉尘爆炸危险源信号的实时检测及预警系统。该系统综合应用工业控制、PLC控制、智能测控终端无线传输、云平台数据管理等技术。采用传感器分别监测除尘器运行时的进出风口压差、除尘器运行状态、高压脉冲喷吹压力和箱体温度。当监测信号不在系统预设的合理范围时,PLC输出就地预警信号,监测信号也可通过无线传输模块上传到云平台。运用云平台的数据分析功能,实现除尘器运行状态系统化监测和综合管理。

A real-time detection and warning system for dust explosion hazard signal of bag filter is developed.The system integrates industrial control,PLC control,wireless transmission of intelligent measurement and control terminal,cloud platform data management and other technologies.Sensors are used to monitor the pressure difference between the inlet and outlet of the dust collector,the operation status of the dust collector,the high-pressure pulse injection pressure and the temperature of the box.When the monitoring signal is not within the reasonable range preset by the system,the PLC outputs the local warning signal.Monitoring signals can also be uploaded to the cloud platform through wireless transmission module.The data analysis function of cloud platform is used to realize the systematic monitoring and comprehensive management of dust collector operation status.
