Embodiment approach 1

[0025] Embodiment 1. Detection of ice thickness and sub-ice water level:

[0026] First, place the sensor shown in the attached figure in the water to be measured when it is not frozen or cut through the ice layer in the frozen state and place it vertically in the ice water with one end facing down, and the sensor should have some metal detection contacts exposed to above the ice and submerged at the bottom of the ice. The external working power supply and the data processing instrument are connected to the sensor wire connection socket (11) through a multi-core waterproof cable. When detecting, the single-chip microcomputer control circuit (7) inside the sensor first sends a conduction control signal to the scale decoding switch circuit (8) in the order from top to bottom under the action of the embedded special software, so that each scale decoding switch circuit ( 8) According to the order from top to bottom, it is turned on separately. When a certain scale decoding switch...

Embodiment approach 2

[0027] Embodiment 2. Detection of the water level under the ice:

[0028] First, place the sensor shown in the figure vertically in the ice water with one end facing downwards. Part of the metal detection contacts of the sensor should be submerged in the water at the bottom of the ice layer, and the height at the bottom of the sensor should be calibrated to obtain its initial value. The external working power supply and the data processing instrument are connected to the sensor wire connection socket (11) through a multi-core waterproof cable. When detecting, the single-chip microcomputer control circuit (7) inside the sensor sends a conduction control signal to the scale decoding switch circuit (8) in the order from bottom to top under the action of the embedded special software, so that each scale decoding switch circuit ( 8) According to the order from the bottom to the top, it is turned on separately. When a certain scale decoding switch circuit (8) is turned on, the detec...

Abstract

The invention is a ice thickness sensor and the measuring method belonging to automatic detecting technology field, the positive electrode of the detecting power in the sensor forms a detecting loop together with the each metal detecting contactor arranged according to the scale, inner scale decoding switch circuit, conduction identification circuit and the negative electrode of the power through the measured media including water, ice, air between the inner and outer walls of the sensor, the inner microchip control circuit in the sensor generates decoding switch control signal according to a fixed coding order, the sensor is connected whose detection circuit correspondent to the metal measuring contactor to carry on the ice thickness measurement, the sensor can carry on fixed point continuous automatic detection to the ice thickness in river, reservoir, long distance transmission project, environment detection and so on.

Description

technical field [0001] An ice layer thickness sensor and a detection method thereof belong to an invention in the technical field of automatic detection. It is a sensor that can automatically and continuously detect the thickness of the ice layer at fixed points in river channels, lakes, reservoirs, long-distance water transmission projects, polar expeditions, geological and environmental monitoring, and various hydropower projects. device. technical background [0002] At present, there are few sensor devices at home and abroad that can detect the thickness of the ice layer automatically and continuously at fixed points in the process of ice layer generation and disappearance under freezing conditions in winter. There are two types of ice production and consumption detection technologies at home and abroad. The first is the direct measurement method, which relies on manual ice cutting or drilling to directly measure ice thickness and water level through a scale. Hydrologic...
