摘要
针对CX55B型挖掘机的油液监测技术上存在的问题,提出了利用AVR处理器控制激光产生脉;中,采用双光路光纤传感器进行信号调制,然后通过对数和差动放大后输入AVR进行处理得到油液污染信息的设计方法。改进后的监测系统较好地提高了测量精度。此方法也适用于其他同类监测技术的挖掘机。
Analyzed the problem which the CX55B excavator oil liquor monitor technology existed,proposed the AVR to control laser and produce the pulse, and processed signal through dual paths of ray optical fiber sensor and electric circuit enlargement, obtained the oil liquor pollution information by AVR. The monitor system increases the measuring accuracy after the improvement. The method is also suitable for other similar excavators.
