    摘要:

    對蜂蜜含水率的檢測應提供便攜,、快速,、精確、適于在線檢測且能克服溫度對測量結(jié)果影響的儀器,。在實驗基礎(chǔ)上，基于蜂蜜電導率的檢測原理,，設(shè)計了數(shù)字式蜂蜜含水率檢測儀,。以洋槐蜂蜜為對象，通過實驗建立了蜂蜜含水率（17%～43%）,、溫度（5～40℃）和電導率之間的數(shù)學模型,。以8位單片機為控制器，DJS—1型電極為電導率傳感器,，DS18B20為溫度傳感器,，設(shè)計了檢測儀的硬件系統(tǒng)，利用單片機C語言編寫程序,。檢測實驗結(jié)果表明：每個樣品的測量時間在3s內(nèi),，測量精度為±0.5%。

    Abstract:

    In order to offer a meter with the characteristics of easy taking,quickly measuring, high precision, being suitable for online detection, and overcoming influence of temperature on measurement for honey water content detection, based on the experiment and electrical conductivity detection principle, a honey water content meter was designed. Firstly, yellow-locust honey was used to establish the mathematical model among water content (17%~34%), temperature (5~40℃) and electrical conductivity. Then the hardware was designed with single chip micro-computer (SCM) of 8 bits as controller, DJS—1 electrode and DS18B20 as sensors of electrical conductivity and temperature, respectively. The software was programmed with C language of SCM. The detection results showed that the measurement time of one sample was within 3s and the precision was ±0.5%.
