[0002] Tide, as a key natural phenomenon in the ocean, has a significant impact on fields such as marine engineering, navigation and port management. With the surge in the number of long-distance channel dredging projects in coastal areas, for example, the channels of Lianyungang Port, Dafeng Port and Zhanjiang Port are more than 50 kilometers offshore. In such long channel dredging projects, accurate measurement of tide level has become the key to determining the accuracy of bathymetry.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. Tidal data is monitored using hydraulic and float-type water level gauges. The data is then sent to the tide processing system via a communication cable for analysis and processing. The analyzed and processed data is then transmitted to the BeiDou-3 short message transmission system. The system then sends the field data in real time to the BeiDou operation platform for summary and distribution. This can reduce the impact of poor network signals in offshore areas on data transmission and facilitate real-time transmission of monitoring data. Monitoring is performed using two different types of water level gauges, hydraulic and float-type, and subsequent analysis of the two sets of data reduces the probability of errors in single detection data. The hydraulic and float-type water level gauges can also be used to regularly calibrate the hydraulic and float-type water level gauges. 2. When the upper and lower hemispheres are fitted together, the sealing ring is embedded in the placement groove and blocks the joint between the upper and lower hemispheres to seal, reducing the probability of water seeping through the gap between the upper and lower hemispheres. When the elastic card and the card slot are aligned, the bolt holes on the upper and lower hemisphere flanges are aligned.

The fixed anchor is fixed to the seabed. By fixing the fixed anchor grip to the seabed, the buoy can be fixed and the probability of the buoy drifting and displacement under the impact of the water flow can be reduced. The anchor chain system is equipped with two sets, one on each side of the base. Reinforcement from both sides can further improve the fixing effect, thereby further reducing the probability of the buoy drifting and displacement caused by the water flow. 6. The fixed ring slides and abuts against the outside of the anchor grip to limit the rotation of the anchor grip, which is convenient for the storage of the fixed anchor when not in use, thereby facilitating the storage and transportation of the fixed anchor. The fixed ring slides and abuts against the outside of the anchor grip to limit the rotation of the anchor grip, which is convenient for the storage of the fixed anchor when not in use, thereby facilitating the storage and transportation of the fixed anchor. When the anchor grip rotates away from the anchor rod and forms a 60-degree angle with the anchor rod, the limit block abuts against the anchor rod to limit the rotation of the anchor grip. It is fixed by bolts and nuts. Under a large tensile force, the nuts are easy to loosen, causing the anchor grip to continue to rotate. The unlimited rotation of the anchor grip will eventually lose its function of gripping the seabed. The setting of the limit block limits the stroke of the anchor grip and reduces the probability of the anchor grip over-rotating and losing its grip. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present application embodiment discloses a tide measuring device based on BeiDou-3 short message data transmission, referring to Figure 1 and Figure 2, including a base 1 placed on the bottom of the water, a water pressure type water level gauge 2 is installed on the base 1, the water pressure type water level gauge 2 is used to monitor tidal changes, the power supply voltage is 12V, and the static pressure type water pressure type water level gauge 2 is made of 316 stainless steel. The static pressure type water pressure type water level gauge 2 is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It has good anti-interference performance, intelligent and complete mature circuits, and a diffused silicon chip sensitive element pressure sensitive sensor, which can easily cope with different pressures, convert the static pressure into an electrical signal, and then after temperature compensation and linear correction, convert it into a standard electrical signal for transmission via RS485. The water pressure type water level gauge 2 is connected to a communication cable 3, and the communication cable 3 is wrapped with a corrugated tube to prevent Scratches and extrusions, a float 4 is provided at one end of the communication cable 3 away from the water pressure water level gauge 2, the communication cable 3 can be used to transmit the data monitored by the water pressure water level gauge 2, and is also a connector connecting the water pressure water level gauge 2 and the float 4, the float 4 floats on the water surface, and a float type water level gauge 0 is fixedly installed on the float 4 outside the float 4, in order to balance the float 4, multiple float type water level gauges 0 are arranged around the float 4, and the monitoring data of multiple float type water level gauges 0 are averaged to improve the monitoring accuracy, the float 4 is installed with a tide level processing system 5, a BeiDou-3 short message transmission system 6 and a battery 7, the communication cable 3 is inserted into the float 4 to connect the tide level processing system 5, the communication cable 3 is inserted into the float 4 and is watertightly treated, and the watertight treatment adopts a double-locking corrugated hose with a card sleeve type waterproof and waterproof Explosion cable connector, high strength and good waterproof performance, the tide level processing system 5 is electrically connected to the float water level gauge 0, the BeiDou-3 short message transmission system 6 and the battery 7, the battery 7 supplies power to the tide level processing system 5 and the BeiDou-3 short message transmission system 6, the water pressure water level gauge 2 and the float water level gauge 0 transmit data respectively through different detection methods, and reduce the error value by analyzing the two sets of data, when the water pressure water level gauge 2 needs to be calibrated, the water pressure water level gauge 2 data is calibrated by the data of the float water level gauge 0, the tide data is monitored by the water pressure water level gauge 2 and the float water level gauge 0, and then the data is sent to the tide level processing system 5 for analysis and processing through the communication cable 3, and the analyzed and processed data is transmitted to the BeiDou-3 short message transmission system 6, through the Bei The Dou-3 short message transmission system 6 sends field data to the BeiDou operation platform in real time for summarization and distribution, which can reduce the impact of poor network signals in offshore areas on data transmission and facilitate real-time transmission of monitoring data. It is monitored by two different types of water level gauges, the hydraulic water level gauge 2 and the float water level gauge 0. The subsequent analysis of the two sets of data reduces the probability of errors in single detection data. Normally, the detection data of the hydraulic water level gauge 2 is used as the benchmark, and the data is appropriately adjusted by checking the data of the float water level gauge 0. For example, when the data detected by the float water level gauge 0 is higher than that of the hydraulic water level gauge 2, the data of the hydraulic water level gauge 2 is appropriately increased a little, and the increased data does not exceed half of the data of the float water level gauge 0 that is higher than that of the hydraulic water level gauge 2.The hydraulic water level gauge 2 is relatively accurate but requires regular calibration. The float type water level gauge 0 is less accurate than the hydraulic water level gauge 2 but is relatively stable. Therefore, when there is a large error between the detection data of the hydraulic water level gauge 2 and the detection data of the float type water level gauge 0, the hydraulic water level gauge 2 is calibrated by analyzing the past data errors of the float type water level gauge 0 and the hydraulic water level gauge 2. The calibration method is to correct the data error of the float type water level gauge 0 and the hydraulic water level gauge 2 on the detection data of the hydraulic water level gauge 2 by subtracting the average error of the past data. For example, if the past error between the float type water level gauge 0 and the hydraulic water level gauge 2 was 2 cm, and the current error between the float type water level gauge 0 and the hydraulic water level gauge 2 is 5 cm, then the data error of the hydraulic water level gauge 2 needs to be corrected by 3 cm.

[0029] Reference Figure 1 、 Figure 2 and Figure 5The float 4 includes a lower hemisphere 41 and an upper hemisphere 42. The float 4 is a sphere with a diameter of 50 cm. The lower hemisphere 41 is made of opaque blue ABS engineering plastic, and the upper hemisphere 42 is made of transparent PP polypropylene plastic. The upper hemisphere 42 and the lower hemisphere 41 are integrally formed with a flange 13, and bolts are installed on the flange 13. The lower hemisphere 41 and the upper hemisphere 42 are fixed to each other by bolts. A sealing ring 14 is embedded at the connection between the upper hemisphere 42 and the lower hemisphere 41. The sealing ring 14 improves water tightness and reduces the probability of water seeping into the float 4 from the gap between the upper hemisphere 42 and the lower hemisphere 41. A mounting plate 8 is installed on the lower hemisphere 41. A plurality of abutment columns 15 are fixed on the ball 41. In this embodiment, four abutment columns 15 are provided. Threaded holes are provided on the abutment columns 15. The mounting plate 8 is fixed to the abutment columns 15 by bolts, thereby realizing the installation and fixation of the mounting plate 8 on the lower hemisphere 41. A sealing ring 16 is provided circumferentially on the mounting plate 8. A placement groove 17 is provided for the sealing ring 16 corresponding to the upper hemisphere 42 and the lower hemisphere 41. When the upper hemisphere 42 and the lower hemisphere 41 are fitted together, the sealing ring 16 is embedded in the placement groove 17 and blocks the joint of the upper hemisphere 42 and the lower hemisphere 41 for sealing, thereby reducing the probability of water seeping into the gap between the upper hemisphere 42 and the lower hemisphere 41. The sealing ring 16 A plurality of elastic cards 18 are fixedly provided in the circumferential direction, and a plurality of card slots 19 are provided on the inner wall of the upper hemisphere 42 corresponding to the cards.

The maximum current of the tide processing system 5 and the Beidou-3 short message transmission system 6 does not exceed 3A. The rechargeable lithium-ion battery with a maximum current of 10A fully meets the power supply requirements; the solar panel 9 has an operating voltage of 18V and a power of 20W. The solar panel 9 absorbs solar energy and converts it into electrical energy, which is stored in the battery 7.

The Beidou-3 short message transmission system 6 is installed on the upper hemisphere 42. Since the signal of the Beidou-3 short message transmission system 6 cannot penetrate the solar panel 9 for transmission, the Beidou-3 short message transmission system 6 needs to be placed above the solar panel 9 and fixed to the top of the upper hemisphere 42 by nail-free glue. The cable passes through the solar panel 9 and is connected to the battery 7 and the tide level processing system 5 to achieve electrical connection between the Beidou-3 short message transmission system 6, the battery 7 and the tide level processing system 5, so as to power the Beidou-3 short message transmission system 6 and transmit information; a position indicator light is installed on the float 4. 12. A plurality of position indicator lights 12 are provided. These lights are evenly installed in the upper hemisphere 42 along the circumference of the float 4. The position indicator lights 12 are powered by the battery 7 and can be easily connected to the battery 7 when installed in the float 4. The position indicator lights 12 use red colored lights. Red light has stronger penetrating properties and can better indicate the position. By connecting a photoresistor, the position indicator lights 12 are illuminated only in poor lighting conditions. In bright lighting conditions, there is no need to indicate the position. Even if the position indicator lights 12 are turned on, they are not easily noticed. Not turning on the position indicator lights 12 can save energy. The setting of the position indicator lights 12 can remind nearby ships to pay attention to tide gauge equipment, reducing the probability of ships accidentally colliding with tide gauge equipment.

The anchor rope 111 is installed on the buoy 4, and the anchor rope 111 is arranged five meters below the buoy 4 to reduce the probability of the ship scraping the anchor rope 111 and the probability of the anchor rope 111 being scraped and pulled by the ship. The fixed anchor 112 is installed on the end of the anchor rope 111 away from the buoy 4, and the fixed anchor 112 is fixed to the seabed. By grabbing and fixing the fixed anchor 112 to the seabed, the buoy 4 can be fixed, reducing the probability of the buoy 4 drifting and displacing under the impact of the water flow. The anchor chain system 11 is provided with two groups, and the two groups of anchor chain systems 11 are respectively provided on both sides of the base 1. Reinforcement from both sides can further improve the fixing effect, thereby further reducing the probability of the buoy 4 being driven by the water flow to drift and displace.

The fixing ring 1123 is slidingly set on the anchor rod 1121, and the anchor catch 1122 rotates toward or away from the anchor rod 1121. When the anchor catch 1122 rotates close to the anchor rod 1121 to abut against the anchor rod 1121, the fixing ring 1123 slides and abuts against the outside of the anchor catch 1122 to limit the rotation of the anchor catch 1122, which is convenient for the storage of the fixed anchor 112 when not in use, thereby facilitating the storage and transportation of the fixed anchor 112. When the fixed anchor 112 needs to be used, the fixing ring 1123 is driven to slide The limit block 20 limits the stroke of the anchor grip 1122, thereby reducing the probability of the anchor grip 1122 losing its grip due to excessive rotation.
