| Abstract: | The high oil temperature in the present hydraulic system leads to the system protection. Here, the paper pre- sents an intelligent oil temperature detection and alarm system based on single chip microcomputer. The principles of the pro- posed 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 CuS0 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. |
