Embodiment 1

[0041] see Figure 1 to Figure 3 , the intelligent monitoring device of the tidal water level monitoring of the present embodiment comprises tide gauge 1, buoy 2 and fixed assembly 3, and tide gauge 1 comprises cable 4 and housing 5, and housing 5 is cylindrical, and cable 4 is from housing 5 upper end Extending to the inside of the casing 5, the inside of the casing 5 is sequentially installed with a pressure sensor 6, a temperature sensor 7, a sound velocity measurement unit 8, a storage calculation unit 9 and a battery unit 10, a pressure sensor 6, a temperature sensor 7, and a sound velocity measurement unit. The units 8 are all connected to the storage calculation unit 9, the pressure sensor 6 is used to monitor the pressure at the zero point of the tide gauge 1, the sound velocity measurement unit 8 is used to measure the propagation velocity of sound in seawater at the depth where the tide gauge 1 is located, and the storage calculation unit 9 It is used to calculate an...

Embodiment 2

[0045] see Figure 1 to Figure 3 , based on the above-mentioned intelligent monitoring device for tide water level monitoring, this embodiment also provides a working method for using the above-mentioned device to monitor the tide level, including the following steps:

[0046] Step 1, the determination of water depth, the acoustic distance measuring unit 15 in the buoy 2 emits sound waves underwater, and calculates the water depth by the time when the sound waves reciprocate on the water surface and the bottom of the water ;

[0047] Step 2, the calculation of the seawater density at the target depth, the internal storage and calculation unit 9 of the tide gauge 1 uses formula one: Calculate the seawater salinity,

[0048] Specifically, among them, Salinity, in units of ; speed of sound, unit ; Seawater temperature, unit ℃; depth, unit ;in Measured by the temperature sensor 7 in the tide gauge 1; Measured by the sound velocity measuring unit 8; Measured...

Embodiment 3

[0054] see figure 1 , the present embodiment provides a method for placing an intelligent monitoring device for tidal water level monitoring, comprising the following steps:

[0055] Step 1. Install the tide level gauge 1 into the base 19, place the tide level gauge 1 at a predetermined position on the sea, slowly release the base 19 to the bottom of the sea, and quickly locate the coordinate position of the base 19 in the navigation software ;

[0056] Step 2. In the suspended state, because the measuring vessel will be affected by the sea current and sea wind, its position will move. During the casting process, the connected lead cable 18 needs to be released at an even speed so that it is distributed in a straight line on the seabed, and the single anchor 16 throws on the seabed, quickly locate the coordinate position of single anchor 16 in the navigation software ;

[0057] Step 3, place the buoy 2 on the sea surface.

[0058]Specifically, the buoy 2 is connected to ...

Abstract

The invention relates to an intelligent monitoring device for tidal water level monitoring and a working method thereof, comprising a tide level gauge, a buoy and a fixed assembly, the tide level gauge includes a cable and a housing, the cable extends from the upper end of the housing to the inside of the housing, and the inside of the housing is equipped with Pressure sensor, temperature sensor, sound velocity measurement unit, storage calculation unit and battery unit, pressure sensor, temperature sensor, sound velocity measurement unit are all connected with storage calculation unit, the pressure sensor is used to monitor the zero position pressure of the tide gauge, and the sound velocity measurement unit is used to measure The propagation velocity of sound in seawater at the depth where the tide gauge is located, the storage calculation unit is used to calculate and store data including seawater pressure, seawater temperature and sound velocity. The present invention can solve the problem that the existing self-contained tide level gauge cannot calculate the tide level data of the monitoring area according to the actual density of the seawater at its depth, which causes the tide level and the actual tide level in the monitoring area recorded and stored by the self-contained tide level gauge quite different issues.

Description

technical field [0001] The invention relates to the technical field of marine hydrological detection, and more specifically, to an intelligent monitoring device for tide water level monitoring and a working method thereof. Background technique [0002] Ocean tide level data is an important element of marine hydrological observation. The precise measurement and forecast of tide level has very important application value for navigation and transportation, ocean engineering, disaster prevention and mitigation, marine fishery, and scientific research. [0003] At present, tide level measurement units mostly adopt the method of throwing self-contained tide level gauges to check tides at fixed points at sea. The measured data is stored in the instrument itself. [0004] According to the water pressure value, seawater density and the gravitational acceleration of the tide point, the water depth value at the zero point of the tide point instrument can be calculated, and then the wa...
