Description

Technical Field

[0001] The utility model relates to the technical field of hole depth measuring devices, in particular to a hole depth measuring device based on UWB technology. Background Technique

[0002] UWB technology is a wireless carrier communication technology, whose operating frequency band is usually between 3.1 GHz and 10.6 GHz, and the signal bandwidth exceeds 500 MHz. It has the advantages of high precision, high real-time performance, strong anti-interference ability, etc., and can achieve centimeter-level or even millimeter-level positioning accuracy, which makes it have potential application value in hole depth measuring devices. The hole depth measuring device based on UWB technology mainly measures the distance by using the flight time of UWB signals. This device usually consists of a transmitter, a receiver, and a processing unit. The transmitter emits ultra-wideband pulse signals, and the signals are received by the receiver after propagating in the hole. The processing unit then calculates the depth of the hole according to the propagation time of the signals and the speed of light.

[0003] The existing hole depth measuring device based on UWB technology generates stable UWB pulse signals through the transmitter and has sufficient transmission power to ensure that the signals can cover the entire depth of the hole to be measured. Then, the receiver accurately receives and measures the arrival time of the UWB signals. At the same time, the receiver also needs to have the ability to resist multipath effects and noise interference. Finally, the processing unit is responsible for calculating the depth of the hole according to the received signal time and the speed of light. It also needs to have data processing and storage functions to analyze and record the measurement results.

[0004] During the measurement process of the hole depth measuring device, if there are obstacles in the hole, it may affect the propagation of UWB signals, resulting in inaccurate measurement results. However, the existing hole depth measuring devices cannot avoid the entry of external obstacles into the hole during operation, resulting in signal occlusion and affecting normal measurement work. For this reason, we propose a hole depth measuring device based on UWB technology. Content of the Utility Model
