Snow thickness measurement recorder

Abstract

The purpose of this invention is to provide a kind of device that can measure the thickness of snow cover and record the geographic location of the measuring point automatically at the same time. A sharp cone is installed at the bottom of the probe rod, a distance detection unit is installed at the top of the probe rod, and a global positioning receiver, microprocessor, power supply, memory module, tilt sensing module and man-machine interface are installed; the measurement process can be operated with one hand and one button; The memory interface saves the measurement data to a USB flash drive, which is convenient for saving in other media. The snow thickness measurement recorder constructed by the present invention has been successfully applied to the Arctic and Antarctic polar scientific surveys. Its ergonomic design can be operated by one person and one hand, reducing the number of personnel for each measurement from 2 to 4 to 1 to 2 people, the measurement workload is greatly reduced, and human error is reduced. Therefore, the snow cover thickness measuring recorder constructed by the present invention has broad promotion prospect.

Description

technical field [0001] The invention relates to a snow thickness measuring recorder, more specifically, it belongs to a measuring device for measuring the snow thickness and simultaneously automatically recording the geographic location of the measuring point in a snowfall or snow accumulation area. Background technique [0002] The current global climate change is rapid and irregular, and extreme weather conditions occur frequently. This situation requires a more detailed observation of global climate change. Snow-covered areas are an important factor affecting global climate location changes, and there is a wide demand for the measurement of snow cover thickness. Traditional snow thickness measurements mostly use the following devices and methods: [0003] 1. Traditionally, measuring rulers, steel rulers, and probe rods are used to measure snow thickness, record snow thickness, and record GPS location information. Sometimes a guide is needed, and in some areas armed perso...

Problems solved by technology

[0003] 1. Traditionally, measuring rulers, steel rulers, and probe rods are used to measure snow thickness, record snow thickness, and record GPS location information. Sometimes a guide is needed, and in some areas armed personnel are also required to prevent wild animals from attacking. Therefore , the measurement of snow thickness according to the line requires the cooperation of 3 to 4 personnel, which is inefficient

[0004] 2. Use auxiliary snow cover measurement devices, such as U.S. Patents US5815064, US5864059 and US7040146, etc. disclose several snow cover thickness measurement devices, which can display or record the measured snow cover thickness, but there is no essential difference between the method of use and the traditional measurement method. The difference is that it is still necessary to manually record the geographic location information of the GPS receiving device, and the measurement accuracy is related to the operator's use method during measurement, and the number of measurement personnel that needs to participate has not decreased

[0005] 3. Use satellite remote sensing to measure a large area. Remote sensing can quickly measure snow thickness in a large area, but the measurement accuracy is relatively low, especially when there is a frozen snow layer, the error will make the measurement results unusable

[0006] The above methods or equipment have limitations, and it is difficult to meet the needs of the growing snow thickness measurement. It is necessary to develop an efficient and accurate measurement device
