| 摘 要： | 针对当前液态施肥机在液肥的精确及定量控制等方面存在的不足,以单片机作为控制核心,采用投入式液位传感器进行数据采集,将液位的变化转换成电压变化,再利用A/D将模拟量转化成数字量;同时,通过单片机处理将电压值换算成相应的液位高度值及容量值并显示,并用Mat Lab分析试验数据。结果表明:液位高度值各容量值测量误差均满足实际要求,可应用于液态施肥机。

| Abstract: | Aiming at the shortage of liquid fertilizer in agricultural machinery currently, liquid fertilizer precise, quantita-tive control is one of the limiting factors.This paper takes the microcontroller as the control core, using input liquid level to acquire data sensor, convert changed liquid level into voltage variation, then use A/D transform analog quantity into digital quantity, at the same time, processing through the MCU to convert voltage values into the corresponding capacity value and display.Finally using MATLAB analysis of test data, the results show that the measuring capacity value and the height of liquid level value error are concerned with the container, but the error meets the actual requirements, can be applied to the liquid fertilizer applicator. |
