Problems solved by technology

However, changes in temperature will lead to changes in parameters such as seawater density, buoyancy, and acoustic conductivity, so it will directly affect the measurement accuracy of these instruments. The most commonly used float type tide gauges also need to set up tide wells, which is not easy
With the deepening of marine development, there are new requirements for the timeliness of tide level monitoring, the simplicity of equipment, and the accuracy of data, but the current tide gauge technology has not yet met the requirements

Embodiment

[0044] Taking 300 electrodes as an example below, the specific operation of the present invention is as follows:

[0045] The implementation is carried out in the Shilaoren sea area of ​​Qingdao, which is a regular semi-diurnal tide with a tidal range of about 2 meters. The length of the resistivity measuring device used in the test is 3 meters, which meets the range of tide level variation; the electrode ring spacing is 1cm, and the judgment accuracy of the seawater-air interface is 0.5cm, which is half of the electrode spacing. Choose 301 nylon modules and 300 electrode rings, insert the electrode ring welded with insulated wires on the side of the nylon module with the boss, and then insert the groove side of the second nylon module on the upper part to make the electrode ring tight Hoop between the nylon modules, repeat the socketing until all are completed, and all the wires pass through the formed nylon module lumen. After pressing, pour vulcanized rubber into the tube ...

Abstract

The invention discloses a system and a method for remotely and automatically monitoring ocean sea levels in real time. The system comprises an upper computer with a signal receiver, a wave elimination tube with a built-in resistivity measurement device, a central control unit connected through an insulated wire and the resistivity measurement device and provided with a control program, a GPRS (General Packet Radio Service) module connected with the central control unit and provided with an antenna, and a solar power supply device. The resistivity measurement device is composed of pluggable nylon modules and electrode rings between the pluggable nylon modules. The monitoring method comprises the following steps of: selecting the numbers of the nylon modules and the electrode rings according to the change range of a sea level to be tested; fixing the resistivity measurement device formed by inserting and connecting the nylon modules and the electrode rings and the wave elimination tube in the bank, and collecting vertical upward resistivity values circularly and repetitively; and finally, obtaining the sea level information by analyzing the resistivity values. According to the system and method disclosed by the invention, the sea level information can be issued automatically, accurately and continuously in real time; supports are provided for ocean engineering construction, safety monitoring, waterway traffic and the like; and the method is especially applicable to remotely reporting the sea level of an extreme sea condition and the like.

Description

technical field [0001] The invention relates to a remote real-time automatic monitoring system and method of ocean tide level to realize remote real-time automatic monitoring of ocean tide level and belongs to the technical field of ocean. Background technique [0002] Under the action of tidal force, seawater ebbs and flows, and the change of ocean tide level reflects the difference in time and space on the basis of following the periodic law. Tide level information has an important impact on marine transportation, ocean engineering, and meteorological research. At present, there are many technical means applied to the monitoring of ocean tide level. Commonly used ocean tide level monitoring instruments include pressure water level gauges, float type tide gauges, acoustic tide gauges, etc. However, changes in temperature will lead to changes in parameters such as seawater density, buoyancy, and acoustic conductivity, so it will directly affect the measurement accuracy of t...
