摘　　要：介绍了利用32位ARM芯片LPC2138为核心控制器构成的矿用空压机电机保护器,保护器实时检测空压机电机的各种工作参数,对各种故障信号进行报警并根据故障类别实现了立即保护、延时保护、只报警不保护等功能,最后将信息通过RS-485总线传输到地面计算机。空压机电机保护器具有功能齐全、使用方便等特点。Introduces a motor protector of air compressor used in coal mine, which uses the ARM chip- LPC2138 as core controller. This motor protector can check all kinds of working parameters of the air compressor motor on spots and give an alarm to the fault information and realize immediate protection, time - delay protection or only an alarm not protection. It also can transmit the information to ground computer by RS - 485 bus. This motor protector of air compressor has excellent characteristics, such as complete function, convenient to use and so on.
