大型离心通风机的监控小型化平台设计与实现

Monitoring Platform Design and Implementation of Large Centrifugal Fan

当前的大型离心通风机的参数监测、运行控制以及数据处理系统都是挂靠在大型DCS控制系统中,无法实现小型化独立控制。设计并实现了一种大型离心通风机监控的小型化平台。监控平台依据一体化、模块化的设计思想完成小型化设计,硬件设计中以ARM Cortex-M3系列LPC1752芯片为核心处理模块,主要包括液晶显示模块、键盘、声光报警模块、片外EEROM存储电路等模块,将获取的大型离心通风机各类参数发送至LPC1752芯片,依据参数的改变对大型离心通风机的工作状态进行改变,使其达到通风要求,分析了监控平台能够实现的功能,给出软件设计整体流程图,同时详细分析了串口通信功能和远程监控功能。以GAF33.5-20-1大型卧式、动叶停车机械式可调轴流式矿井通风机为研究对象,仿真实验结果表明,设计的平台进行大型离心通风机电机电流、输出功率、温湿度监控时与实际值相似度高,说明设计的平台具有较高的精度和较强的应用性。

A miniaturization monitoring platform of a large centrifugal fan is designed and realized. The monito- ring platform is completed by the miniaturization design with integrated and modular design ideas. ARM architecture （M3 series LPC1752 chip） is used as the core processing module in hardware design, which mainly includes liquid crystal display module, keyboard, sound and light alarm module, outside EEROM memory circuit modules. All pa- rameters of the large centrifugal fan are obtained and sent to the LPC1752 chip. The work condition of the large cen- trifugal fan is changed according to the change of the parameters, so as to achieve the ventilation requirements. Ac- cording to the functions of monitoring platform, a serial port communication and remote monitoring, the software is designed and developed. By taking the large mine ventilator GAF33.5 -20 - 1 as the research object, the experi- mental results show that the proposed system has high reliability and practicability.
