摘要
本文研究并设计了一种基于MSP430单片机的高精度和高准确度的液位监控系统,从硬件设计、软件设计、系统抗干扰、开浇停浇电压补偿和参数线性化五个方面详细描述了整个系统。系统选用了高集成度、超低功耗的混合信号处理器MSP430F449,实现了信号的采集和处理,对液位进行实时的监控并且完成了与LTC1446、LTC1451的数据传输任务。除此之外,还可以根据液位变化情况进行人工调整。系统解决了以往液位监控系统中存在的问题,达到了高准确度和高精度液位监控仪器的各项标准。
A new crystallizer liquid level measuring system with high accuracy and high precision is developed in this paper. It described the system according to the hardware design, software design, anti-jamming design, voltage compensation for opening and stopping and parameter linearization. We choose an advanced integrated mcu with extremely low power consumption Msp430F449 as the main controller to Realize signal sampling, processing and its conversion in the system. It also timely surpervise the liquid level and transmission data to LTC1446 and LTC1451 and receive related date from them. Anything else, it also be adjusted artificially aecroding to the liquid-level change. The system reach the high standar of liquid-level with high precision and accuracy to solve the problems that have been existing in the past.
