低功耗二甲醚复合燃料浓度检测仪的设计

The Design of Low Power Consumption Dimethyl Ether Fuel Consistency Detecting Instrument

本文描述了一种以MSP430微控器为核心的二甲醚复合燃料浓度检测仪,仪器具有浓度显示、报警和事件记忆等功能。为了降低系统功耗,采用了非关键部分分时工作机制,设计了敏感元件闭环限流电路,并给出了试验结果。实际应用证明该仪器功耗低、性能可靠、操作简便。

In this paper, a low power consumption dimethyl ether fuel consistency detecting instrument with MSP430 MCU as the core component is presented. This instrument supported the functions of fuel consistency over-proof display, alarm,episodic memory and so on. In order to reducing power consumption, the non-critical parts working in a time-sharing mechanism. The closed-loop controlled current limit circuit designed for sensor is also shown. The experimental results are also shown. It is proved to be a reliable, effective and easy to be operated.
