Embodiment Construction

[0060] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0061] like figure 1 The flow chart of the grain moisture measuring method of the present invention shown, comprises the following steps:

[0062] S101 detects the moisture contained in the grain to be measured and the ambient temperature of the grain to be measured according to the moisture measurement request from the user;

[0063] S102 performing data fusion processing on the detected moisture data contained in the grain to be measured and the temperature data of the environment where the grain to be measured is located, to obtain actual moisture data of the grain to be measured;

[0064] S103 sends the obtained actual moisture data of the grain to be measured to the display device for viewing by the user.

[0065] Further, the detection of the moisture contained in the grain to be tested and the ambient temperature of the grain to be tested ...

Abstract

The invention discloses a resistive grain moisture measurement system. A moisture measurement method provided by the invention can perform grain moisture measurement continuously in a real-time manner and upload the grain moisture value and the temperature value of the grain environment in a real-time manner, and can also generate alarm information to remind users and automatically realize shutdown in time to avoid loss, so that the drying efficiency is improved by 12 to 15%. According to the method, the moisture measurement range can reach up to 11to 40%, and the temperature measurement range can reach up to minus 40 to 180 DEG C. According to the invention, the measured resistance signals are converted into frequency signals, and the grain moisture is measured by adopting a frequency measuring and period measuring method; an oscillating circuit is used to convert the collected signals, the measurement is performed by a single-chip microcomputer, linearization is carried out through a software optimization design and an appropriate algorithm, so that the moisture measurement can be performed quickly and accurately on samples of various types of food grains.

Description

technical field [0001] The invention relates to the field of moisture detection, in particular to the field of grain moisture detection. technical background [0002] Grain moisture detection is of great significance to grain purchase, transportation, storage, and processing trade. Excessive moisture wastes transportation capacity and storage capacity, promotes vigorous food life activities, and easily causes food heat, mildew, insects, and other biochemical changes. However, if the grain moisture is too low, the grain weight will be reduced, which will affect the grain quality. Therefore, moisture has always been an important quality criterion of grain. [0003] Grain moisture detection technology is generally divided into direct method and indirect method. The direct method is to directly remove the moisture in the grain by drying or chemical methods, and detect the absolute moisture content of the sample. The direct method of moisture detection has high detection accu...
