Water bottom measurement device, system and method

Abstract

The present invention provides a water bottom measurement device, system and method. The method comprises the steps in that: a hiding detector body is connected with an anchor through an anchor chain;the hiding detector body is internally provided with a plurality of electromagnetic launch cabins; each electromagnetic launch cabin is internally provided with one emergency communication buoy; thehiding detector body is provided with an antenna, and the antenna and each electromagnetic launch cabin are connected with a center control module. The present invention provides a technical scheme ofimproving the applicability and the reliability of the water bottom measurement device, system and method in various scenes employs a water bottom snorkeling mode to overcome the interference problemof the water bottom environment for the underwater detection, a reliable long-term power supply solution scheme is provided, and the emergency communication buoys are employed to improve the disastertolerance of data communication. Through implementation of the optimal scheme, a more reliable device and a networking scheme are provided for a current water bottom detection demand, and the cost oflaying, putting and maintenance can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of underwater measuring equipment, and in particular relates to an underwater measuring device, system and method. Background technique [0002] In the fields of hydrological monitoring and fishery, there is a large demand for obtaining various underwater parameter information through underwater measurement. The existing underwater measurement devices can meet most of the needs through the settings of various sensors and collectors. However, in some special application scenarios, there are still limitations. [0003] For example, in inland river and lake basins with low water flow rate, the silt on the bottom of the water will have a great impact on the sensitivity and accuracy of the sensor. How to ensure the long-term and stable power supply of the measuring device is also a difficult problem to solve. [0004] In addition, the data transmission and communication of underwater measurement devices usually rely on th...

Problems solved by technology

[0003] For example, in inland rivers and inland lakes where the water flow rate is small, the silt on the bottom of the water will have a greater impact on the sensitivity and accuracy of the sensor. How to ensure long-term and stable power supply of the measuring device is also a difficult problem to solve

[0004] In addition, the data transmission and communication of underwater measurement devices usually rely on the antenna, and when the antenna fails or is damaged due to unpredictable factors, the underwater measurement device will completely lose contact with the terminal that collects information. Unsuccessful urgent data cannot be transmitted
