Circular parallel electrode object dielectric property detection clamping device and detection method thereof

Abstract

The invention discloses a circular parallel electrode object dielectric property detection clamping device and a detection method thereof. A lower parallel electrode plate is fixedly arranged on a device base and maintained to be level. An upper parallel electrode plate is connected on a support via a slide adjusting device. The support is connected with the base. The upper electrode plate connected on the support is enabled to translate upwardly and downwardly via adjusting a coarse adjusting device and a fine adjusting device so that change of distance between the two electrode plates and clamping of effective parallel of the clamped object by appropriate clamping force can be realized. The adjusting device is also provided with a slide rheostat. Distance of the parallel electrode plates is converted into electric signals via the slide rheostat and a distance measuring circuit and then the electric signals are operated via a single-chip microcomputer and displayed on a displayer. Clamping of effective parallel of the clamped object by appropriate clamping force can be realized when the electrical properties of the object are detected, and distance in clamping can be timely and accurately read. Compared with conventional clamping devices, the clamping device has advantages that operation is convenient, detection quality and precision are higher and the related information can be directly displayed.

Description

technical field [0001] The invention relates to a circular parallel plate electrode clamping device for quickly detecting the dielectric constant of an object and a detection method thereof, belonging to the technical field of detection instruments. Background technique [0002] At present, the water shortage detection of crops has become a major problem in agricultural engineering. Although the traditional drying and weight loss method can accurately obtain the moisture content of crops, this method has a long cycle and cannot perform live detection, so it has certain limitations. In recent years, with the rapid development of science and technology, some advanced technologies have been applied to the detection of moisture content of crop leaves, including spectral technology and electrical characteristics. As far as the electrical characteristic technology is concerned, the dielectric constant is an attribute of the object, so as long as the relationship between the water ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing technologies and products are relatively simple to manufacture and cannot achieve strict mutual parallelism between the two plates, which greatly affects the measurement accuracy and produces great errors; in addition, it is impossible to directly measure the distance between the plates, and it is necessary to Manual measurement in the later stage increases the difficulty and process of the operation, which is not convenient; there is no intuitive performance for the clamping of the object, which depends entirely on personal feeling, and it is difficult to achieve the operation purpose of clamping the object with an appropriate clamping force
