specific Embodiment approach ： Embodiment approach 1

[0014] Specific embodiments: Embodiment 1. Detection of ice thickness and water level under the ice:

Embodiment approach 2

[0015] First, set the figure 1 The steel string tension adjustment device 6 shown in the figure adjusts the steel string 2 so that its tension reaches a suitable value, and then vertically place the sensor in ice water with one end of the sensor steel string control mechanism 8 facing down (it can be placed in the measured area when it is not frozen) water or dig out the ice layer and place it vertically in ice water when it is frozen), the top is higher than the ice surface to be detected. The special detection instrument is connected with the sensor wire connection socket through a multi-core waterproof cable. During the detection, the steel string pull-in control command is first issued by the special detection instrument, which drives the connected electromagnetic pendulum head 3 and the steel string 2 on the outer wall of the aluminum alloy shell to mechanically deflect through the steel string control circuit, so that the sensor steel string 2 and the steel string 2 The...

Abstract

Chord control digit code transducer and its detecting method are characterized in that steel chord of the transducer is at two states of contact and noncontact with outgoing contract point of the code circuit address inside the transducer under the action of the control signal and the transducer receives continuous address code pulse signal via water and ice to be identified by the internal detecting code circuit to detect the ice thickness and water level value under ice not influenced by electro-magnetic physical performance of the ice so as to finish accurate automatic detection of ice thickness and water level of river, channel, reserviors, long distance transport projects and various hydroelectric ice layer generating and dissolving process.

Description

technical field [0001] A string-controlled digital codec sensor and a detection method thereof belong to an invention in the technical field of automatic detection. It is a high-precision automatic measurement of ice thickness and subglacial water level for river channels, lakes, reservoirs, long-distance water transmission projects, polar surveys, geological and environmental monitoring, and various hydropower projects under freezing conditions. detection sensor device. technical background [0002] At present, there are many technologies and products for water level measurement at home and abroad, but there are few sensor devices that can automatically detect the thickness of the ice layer and the water level under the ice during the process of ice formation and disappearance under freezing conditions in winter. There are two main types of ice production and destruction detection technologies at home and abroad. The first is direct measurement method, which relies on manu...
