针对目前液压系统油温过高导致系统保护的问题,设计了一种基于单片机的智能油温检测报警系统.详细阐述了该智能油温检测报警系统的原理.该智能油温检测报警系统以Atmel公司AT89C51型单片机为主要内核,采用铜热电阻Cu50和摩托罗拉公司MC14433型A/D转换器为温度信号采集装置,并以7448芯片驱动LED显示,在精确测量温度的同时实现油温升高超限报警功能.%The high oil temperature in the present hydraulic system leads to the system protection. Here, the paper presents an intelligent oil temperature detection and alarm system based on single chip microcomputer. The principles of the proposed system is elaborated emphatically. The intelligent oil temperature detection and alarm system takes AT89C51 single-chip microcomputer produced by Atmel company as the main core, adopts copper heat resistance Cu50 and Motorola MC14433 type A/D converter as temperature signal acquisition device, and realizes LED displaying driven by 7448 chip, which measures the temperature accurately and at the same time gives an alarm when the oil temperature increases and exceeds the temperature limits.
