摘　　要：设计研发的“pxb”正压型防爆控制系统采用冗余设计,其控制核心部分采用两块STM32F429核心板子做为控制系统的主机和从机,避免以往采用PLC进行冗余设计时控制隔爆箱设计尺寸大的问题,使整体结构设计尺寸变小,其内置的物联网模块可与远程发送数据信息,方便操作人员及时处理。最后将该正压控制系统应用到正压控制柜中,经过试验发现其确定最高正压等级、最高正压试验、最低正压试验、泄漏试验、换气试验均符合GB/T 3836.5—2021要求。The"pxb"positive pressure explosion-proof control system designed and developed adopts a redundant design.Its control core uses two STM32F429 core boards as the host and slave of the control system,avoiding the problem of large control explosion-proof box design size when using PLC for redundant design in the past,and reducing the overall structural design size.Its built-in IoT module can send data information remotely,making it convenient for operators to process in a timely manner.Finally,the positive pressure control system was applied to the positive pressure control cabinet.After testing,it was found that the highest positive pressure level,highest positive pressure test,lowest positive pressure test,leakage test,and ventilation test all met the requirements of GB/T 3836.5-2021.
