摘要
介绍一种采用廉价单片机AT89C2 0 5 1的智能型太阳能热水器水位水温测控装置。该装置中水位信号采用两线制传输 ,水温信号采用PN结传感器 ,配以精密V/F变换器将温度变换成与频率成正比的电脉冲信号。实践证明 ,整个装置抗干扰能力强 ,可靠性高 ,成本低 。
This paper introduces an intelligent measurement set of water level and water temperature of solar energy water heart, it use single microcomputer-AT89C2051. The signal of water level use two-line-system to transmit and the temperature use PN sensor. With the accurate V/F convertor, the temperature can be transformed to impulse signal whose frequency and temperature is in direct ratio . The practice proved that this set has good anti-jamming, and be cost low, it is worth applying and extending.
