摘要

In short-wavelength near infrared range, design a leaf water measuring instrument which can realize non-destruction and in situ measurement. The system was developed on the basis of Lambert-Beer's law and double-wavelength spectroscopy. The measuring instrument centered with single-chip microcomputer MSP430 was an integrated intelligent system, which can independently accomplish data acquisition, processing, saving, communication and display. The instrument consisted of acquiring module, microprocessor system, software supporting and calibration model. The optical signals were collected by TSL230, a new type of sensor detector, which could convert the incident light into frequency in direct proportion. Choose the light-to-frequency chip simplify the circuit greatly and minimize external disturbance. Experiments were performed on Chinese redbud leaves. The related coefficient of the predicted value and standard value in prediction set was near 0.9. The experiment result indicated this system was feasible to detect leaf water of Chinese redbud non-destruction and fast. The low consumption characteristic was given full consideration in the period of hardware design and software programming. Compared with other apparatus, small volume, light weight, simple structure, low power consumption and anti-interference were the remarkable advantages.
