Distance measuring device based on radio wave wavelength

Abstract

The invention discloses a distance measuring device based on radio wave wavelength, which comprises a storage bin with an inlet and a plurality of wavelength distance measuring pieces arranged in the storage bin. The top of the storage bin is connected with a detachable support plate, the detachable support plate is rotatably connected with a connecting mechanism, and the center of the connecting mechanism is communicated with an inlet of the storage bin. According to the distance measuring device based on the radio wave wavelength, the heights of plastic balls at a plurality of positions in the storage bin can be detected through the plurality of wavelength distance measuring pieces, so that the accuracy of detection data in the storage bin is improved; the plurality of wavelength distance measuring pieces can be driven to move through the arranged connecting mechanism, so that the different wavelength distance measuring pieces can detect data of different positions of the storage bin, and the wavelength distance measuring pieces can perform detection through comparison of front and back data of each wavelength distance measuring device during movement, therefore, whether the wavelength distance measuring pieces are damaged is determined.

Description

technical field [0001] The invention relates to the technical field of radio wave distance measurement, in particular to a distance measurement device based on radio wave wavelength. Background technique [0002] Radio waves refer to electromagnetic waves in the radio frequency band that propagate in free space. The shorter the wavelength and the higher the frequency of radio waves, the more information can be transmitted in the same time. The main principle of use of radar ranging devices on the market is also to use radio The wave method finds targets and determines their spatial location. [0003] In chemical companies, it is often necessary to store some cleaned plastic granular materials first, and then process them. The existing silos generally measure the storage height of the materials by setting a wavelength distance measuring device on the top of the silo. This method of measuring only by one wavelength ranging device has the disadvantage of large measurement erro...

[0003] In chemical companies, it is often necessary to store some cleaned plastic granular materials first, and then process them. The existing silos generally measure the storage height of the materials by setting a wavelength distance measuring device on the top of the silo. This method of measuring only by one wavelength ranging device has the disadvantage of large measurement error, especially when the wavelength ranging device is damaged, it is difficult to find its abnormality because there is no reference object, and because the height of the material cannot be obtained in time and accurately , which may lead to the problem that the feeding of the silo exceeds the maximum limit or is not full, and when the wavelength ranging device detects inaccurate data, the existing wavelength ranging device cannot realize the data measured by the wavelength ranging device Therefore, it is impossible to judge whether the wrong data measured by the wavelength ranging device is due to the damage of the wavelength ranging device, which leads to inaccurate data, or whether the data detected by the wavelength ranging device is caused by external factors.
