A multi-parameter rf online detection device and detection method for double-concealed probe type granary for grain

Abstract

The invention discloses a grain multi-parameter RF online detection device for a double-hidden-probe granary. The device comprises a shell body, a shell cover, a first detection circuit board, a second detection circuit board and a temperature and humidity sensor, wherein the shell body is provided with a built-in containing cavity; the shell cover can be matched with the shell body cooperatively;the first detection circuit board is detachably arranged in the containing cavity, and a first detection probe is arranged on the lower portion of the first detection circuit board; the second detection circuit board is detachably arranged in the containing cavity, the second detection circuit board is detachably connected with the first detection circuit board in a spaced mode, and a second detection probe is arranged on the lower portion of the second detection circuit board; the temperature and humidity sensor is fixedly arranged at the top of the first detection circuit board, and the distance between the first detection circuit board and to-be-detected grains is larger than the distance from the second detection circuit board to the to-be-detected grains. The invention discloses a grain multi-parameter RF online detection method for the double-hidden-probe granary.

Description

technical field [0001] The invention relates to the field of on-line moisture, temperature and humidity detection of grain, in particular to a multi-parameter RF on-line grain detection device and detection method for a double concealed probe type granary. Background technique [0002] The important indicators for the safe storage of grain in the granary are grain moisture, temperature, and humidity. The quality of grain in the granary is directly related to these three factors. The above indicators are necessary conditions for evaluating the quality of stored grains. The heating, mold and insects of grains are closely related to grain moisture, temperature, and humidity. In order to effectively avoid unfavorable phenomena in the process of grain storage, it is particularly important to accurately monitor the grain situation in the granary online. [0003] RF online detection relies on a radio frequency (Radio Frequency) signal source to generate a radio frequency voltage ...

AI Technical Summary

Problems solved by technology

[0007] Based on the above-mentioned traditional grain moisture meter and the new method of detecting grain moisture in recent years, the accuracy of the instrument to detect grain moisture is not high and it is easily disturbed by factors such as temperature and humidity. Therefore, how to reduce the measurement error of the moisture meter is a key issue for online grain water measurement.
