AI Technical Summary

Technical Problem

In the current rice drying process, offline detection is time-consuming and labor-intensive, while traditional resistance methods are destructive and cause food waste. Furthermore, traditional two-plate capacitor detection has low accuracy and short detection time, and cannot accurately represent the actual moisture content of rice.

Method used

By employing a capacitor-type three-plate structure, combined with a BP neural network and genetic algorithm, and through a cross-shaped blade structure and a vibration motor, online moisture detection of rice is achieved, improving detection accuracy and automation, and avoiding grain loss.

Benefits of technology

It achieves high precision and automation in online moisture detection of rice, with a detection error of less than ±0.6%. It has a simple structure, reduces labor costs, and is suitable for the actual working conditions of the grain discharge port of the drying tower.

Abstract

本发明的一种电容式三极板水稻在线水分检测装置属于水分检测装置,是在检测盒体的外侧壁上固定有控制器,在控制器内嵌入检测模型。在检测盒体上部设有隔板,隔板两端中心的固定轴穿过盒体两端的侧板,其一端固定轴与电机的输出端连接;在隔板的上、下两侧分别竖直固定有电极板,两电极板和隔板形成十字形叶板;在检测盒体的前后侧板内分别固定有电极板,检测盒体的内壁上固定有温度传感器。该装置通过“十”字形叶板将采样、排粮及电容器结合,在装置运行过程中形成三极板平板式电容器,结合BP神经网络和遗传算法进行检测,相对于传统两极板平板式电容器水分检测精度更高,检测过程不会对水稻造成损耗,更适用于烘干塔排粮口水稻的在线水分检测。
