摘要
无线检漏布袋除尘系统是以XBee-pro无线通信模块为基础进行数据传输,利用单片机和PLC来达到控制的目的。由于工作环境中的粉尘进入滤室会吸附在悬浮装置上,导致液位高度上升。本系统主要通过高精度的液位传感器采集装置中液位的高度信息,然后通过高精度的A/D将液位高度信息转化成数字信号传递给单片机,封装成帧结构转发给协调器,协调器接收到发送帧,然后转交给PC机解析、计算出环境中粉尘比例,实现对环境中粉尘比例的检测。在控制过程中,通过给终端XBee-pro发送控制帧信息,传递给单片机解析出控制命令信息,移交给PLC以实现对各个阀的控制。
The wireless dust bag leak detection and filter system is based on wireless radio communication module -- XBee-pro for data transmission. The dust in the work environment will be adsorbed into the filter chamber in a suspension, resulting in the rise of liquid level. In this system, high-precision liquid level sensor acquires the height information of liquid level in the device, and then high-precision A/D converts the liquid level information into a digital signal, and transfers it to the microcontroller package structure where it is packed into frame structure and forwarded to the coordinator. Coordinator receives the frame and sends it to the PC, and then the PC calculates the proportion of dust in the environment through analysis. During the control process, control frame information is sent to the terminal XBee-pro, and passed to the MCU to analyze the control command information which is transferred to the PLC to realize the control on each valve.
