Drill type ice thickness automatic measuring instrument and its measuring method

Abstract

The invention discloses a drill-type ice thickness automatic measuring instrument, which includes an electric drill or an ice breaker, and a back-end processing unit is arranged on the electric drill or ice-breaker, and the back-end processing unit includes a pressure sensor, a rotary encoder, a single-chip microcomputer , A / D conversion module, wireless communication module, display module and power supply module; The pressure sensor is arranged on the drill bit of the electric drill or ice breaker, the pressure sensor is connected with the single-chip microcomputer through the A / D conversion module, and the rotary encoder is connected with the electric drill or The ice breakers are connected by wires, and the rotary encoder, wireless communication module and display module are respectively connected to the single-chip microcomputer. The present invention is improved on the basis of traditional electric drills or ice breakers. Only a back-end measurement unit is added to the traditional electric drills, and the thickness of the ice can be automatically calculated at the moment when the ice is drilled through, which not only overcomes the impurities in the Yellow River water The influence of many factors such as large sand concentration and other factors on the measurement is eliminated, and the trouble of manual recording is eliminated.

Description

technical field [0001] The invention belongs to the field of ice layer thickness measurement, and in particular relates to a drilling-type ice layer automatic measuring instrument and a measuring method thereof. Background technique [0002] In northern my country, due to the relatively cold winter, the freezing period is long. When the ice layer reaches a certain thickness, vehicles and personnel can pass through the ice directly. This brings great convenience to transportation. However, it can be seen from the returned information that due to the complexity of hydrological and geographical conditions, there are often some areas where the local ice layer becomes thinner (commonly known as Qinggou). The Yellow River is located in the northern region. Due to the large latitude span, ice hazards often occur, which poses a great threat to the lives and property safety of people along the coast. To solve the ice problem, we must first understand the basic conditions of ice, a...

Problems solved by technology

The method of using the electrical conductivity of water to determine the thickness of the ice layer is based on the electrical conductivity of water and ice, which is affected by factors such as the purity of the water and the temperature of the ice layer, especially the contact between the bottom of the ice layer and the thickness of the ice layer. The conductivity change characteristics of the interface are relatively complex, and there is no strict boundary point between conductivity and insulation, which brings difficulties to detection
