Description

Technical Field

[0001] This invention relates to the field of tidal meteorological observation technology, specifically to a split-type warning tidal level monitoring and early warning system. Background Technology

[0002] Storm surge is an abnormal rise in sea level caused by strong atmospheric disturbances, such as tropical cyclones (typhoons, hurricanes) and extratropical cyclones. Coastal bays and estuaries are often densely populated areas, and when storms make landfall in these areas, poor drainage often leads to large amounts of flooding, causing significant economic losses.

[0003] The existing fixed tide gauge stations in coastal areas are all located in relatively convex positions on the coastline. The tide level data they monitor cannot reflect the actual backwater process in bays and estuaries. Therefore, they cannot accurately issue accurate tide level warnings to the surrounding people and disaster prevention and mitigation command and decision-making departments, resulting in a disconnect between warning information and emergency response. In addition, the construction of formal tide gauge stations requires huge economic investment and cannot be widely applied.

[0004] Moreover, existing seawater tide monitoring instruments mainly include several types: contact type (mechanical float), non-contact type (ultrasonic, high-frequency radar wave), and submersible type (pressure type). The mechanical transmission recording part of the contact type is complex and bulky, making it inconvenient to install and maintain. The non-contact and submersible types of sensors are affected by environmental factors such as atmospheric pressure, temperature, humidity, and changes in suspended matter concentration, resulting in measurement errors and easy misjudgment of the results.

[0005] CN108732647A discloses a storm surge forecasting method, including storm surge rise forecasting and storm surge occurrence time forecasting. Storm surge rise forecasting includes: collecting data on warning tide levels exceeding h0 from meteorological monitoring stations during a given year (Y) and corresponding wind speed data on the windward side of the monitoring station; establishing a storm surge rise database including the maximum windward wind speed, time-period average wind speed, and storm surge rise of the meteorological monitoring station. Storm surge occurrence time forecasting includes: collecting data on the occurrence time of astronomical high tide levels and storm surge occurrence time from the aforementioned meteorological monitoring stations; establishing a storm surge occurrence time database including the occurrence time of astronomical high tide and storm surge occurrence time. However, this prior art only relates to an idea and does not provide a specific implementation path. Summary of the Invention

[0006] The purpose of this invention is to provide a split-type warning tide monitoring and early warning system. The entire system is designed as a split system, which provides two-way communication for the detection and early warning system while expanding the application scope of the entire system; it minimizes the error in measurement results and effectively avoids misjudgment of results, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A split-type tide level monitoring and early warning system. It includes a warning tide level monitoring module and a warning tide level early warning module.

A positioning rod is slidably installed inside the hollow tube, and the float is fixedly installed on the top of the positioning rod. A first spring is fixedly connected between the positioning rod and the bottom surface inside the hollow tube. A second spring is equidistantly arrayed between the micro switch touch plate and the top surface inside the water tank. The micro switch touch plate is used to trigger the water level monitoring sensor.

[0011] Furthermore, the bottom of the monitoring box is provided with a base with a height adjustment component. The base includes two sets of side frames and a lifting motor fixedly connected between the two sets of side frames. A sliding assembly is provided between the side frames and the outside of the monitoring box. The sliding assembly includes two sets of slide rails. A damper is provided inside the slide rails. The telescopic rod end of the damper is fixedly connected to the top of the side frame.

[0012] Furthermore, the data acquisition system is powered by an LM2596 power chip, with an STM32F103RCT6 as the processor, and peripherals including a MAX485 chip and a relay control module. The water level sensor monitoring system at the monitoring point consists of an 80GHz radar water level gauge. By detecting the radar waves emitted and returned, the system calculates and processes the data to obtain the monitored water level height, which is then transmitted to the data acquisition unit via an RS485 interface.

[0013] Furthermore, the 4G communication system adopts the Air724 4G communication module, which has rich built-in network protocols, integrates multiple industrial standard interfaces, and supports full network compatibility, adapting to different operators and ensuring maximum flexibility. The Beidou communication system adopts the WN-BWS1000-TS Beidou communication terminal, which includes an RDSS module, an RNSS module, a processing module, and an expansion main control board. The RDSS module and RNSS module are connected to the expansion main control board through the processing module, and have satellite short message communication function to realize real-time data transmission.

[0014] Furthermore, the wind-solar hybrid power supply system uses a 600W wind turbine and a 300W photovoltaic panel for power generation, and two 120AH gel batteries are connected in series to form a 24V 240AH power output. It adopts a PWM controller, which has PWM charging function for the wind turbine, overcharge, over-discharge and open circuit protection functions for the battery, and also supports RS485 data output function.

[0015] Furthermore, the meteorological sensor monitoring system consists of a rain sensor, a wind speed sensor, a wind direction sensor, and a temperature and humidity sensor.

The data acquisition system is powered by an LM2596 power chip, with an STM32F103RCT6 as the processor and peripherals including a MAX485 chip and a relay control module.

[0016] Furthermore, the sound and light alarm system uses a QWH35T alarm horn, whose maximum output sound can reach 123dB; it uses red, orange, yellow and blue four-color LED lights as warning lights, and can provide warnings with different colored lights according to different water levels.

[0017] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this invention are: This invention establishes a data acquisition system that acquires parameters from a wind-solar hybrid power supply system, data from a water level sensor monitoring system, and data from a meteorological sensor monitoring system via the standard Modbus protocol. After packaging and processing these data, the system uploads the processed data via a 4G communication system using a serial port pass-through mode. The BeiDou communication system serves as an emergency system and is generally in sleep mode. When the 4G communication system has no signal, the processed data will be uploaded via the BeiDou communication system. The invention discloses specific application methods and provides a connection diagram for the warning tide level monitoring point system, offering a concrete implementation path. The warning tide level early warning module in this invention is powered by a wind-solar hybrid power supply system. The data acquisition system is the core, and the 4G communication system will return instructions to the data acquisition system. The data acquisition system controls the audible and visual alarm system to perform corresponding early warning operations through IO relays. When the 4G communication system has no signal, the instructions will be sent through the Beidou communication system. The entire system is designed as a split system, which provides two-way communication guarantee for the detection and early warning system while expanding the application scope of the entire system.

[0018] This invention incorporates a mechanical signal feedback mechanism within the warning tide level monitoring module and a dual-cavity detection box. Power is used to periodically and quantitatively introduce water connected to the monitored water area into another semi-enclosed cavity. This ensures that the liquid within the semi-enclosed cavity is unaffected by environmental factors such as atmospheric pressure, temperature, humidity, and suspended solids concentration, minimizing measurement errors and effectively preventing misjudgments.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides, for example Figure 1-4 The system shown is a split-type warning tide level monitoring and early warning system, which includes a warning tide level monitoring module and a warning tide level early warning module. The warning tide level monitoring module and the warning tide level early warning module are set as two split monitoring points. Both the warning tide level monitoring module and the warning tide level early warning module include a 4G communication system, a data acquisition system, a wind-solar hybrid power supply system and a Beidou communication system. The warning tide monitoring module is also equipped with a meteorological sensor monitoring system; The warning tide level early warning module is also equipped with a wind-solar hybrid power supply system. Both the warning tide level monitoring module and the warning tide level early warning module upload the monitored data to the IoT backend via the 4G communication system and the Beidou communication system. After processing and analyzing the data, the IoT backend pushes the early warning results to the warning tide level monitoring module and the warning tide level early warning module. The warning tide level monitoring module and the warning tide level early warning module then perform early warning operations based on the early warning results.

[0023] like Figure 1As shown, the warning tide monitoring system is powered by a wind-solar hybrid power supply system. The data acquisition system is at its core, connected to the wind-solar hybrid power supply system, water level sensor monitoring system, meteorological sensor monitoring system, and BeiDou communication system via RS485 interfaces; and connected to the 4G communication system via TTL interfaces. The data acquisition system acquires parameters from the wind-solar hybrid power supply system, data from the water level sensor monitoring system, and data from the meteorological sensor monitoring system using the standard Modbus protocol, packages and processes the data, and finally uploads the processed data via the 4G communication system using serial port pass-through mode. The BeiDou communication system serves as an emergency system, generally operating in sleep mode. When the 4G communication system has no signal, the processed data will be uploaded via the BeiDou communication system.

[0024] The data acquisition system is powered by an LM2596 power chip, with an STM32F103RCT6 as the processor, and peripherals including a MAX485 chip and a relay control module. The water level sensor monitoring system at the monitoring point consists of an 80GHz radar water level gauge. It detects the radar waves emitted and returned, processes the data to obtain the monitored water level height, and finally transmits the data to the data acquisition unit via an RS485 interface.

[0025] The 4G communication system uses the Air724 4G communication module, which has rich built-in network protocols, integrates multiple industrial standard interfaces, and supports full network compatibility, adapting to different operators and ensuring maximum flexibility. The Beidou communication system uses the WN-BWS1000-TS Beidou communication terminal, which includes an RDSS module, an RNSS module, a processing module, and an expansion main control board. The RDSS module and RNSS module are connected to the expansion main control board through the processing module, and have satellite short message communication function to realize real-time data transmission.

[0026] The wind-solar hybrid power supply system uses a 600W wind turbine and a 300W photovoltaic panel for power generation. It uses two 120AH gel batteries connected in series to form a 24V 240AH power output. It adopts a PWM controller and has PWM charging function for the wind turbine, overcharge, over-discharge and open circuit protection functions for the battery, and also supports RS485 data output function.

[0027] The meteorological sensor monitoring system consists of a rain sensor, a wind speed sensor, a wind direction sensor, and a temperature and humidity sensor. It can monitor various parameters in the atmospheric environment in real time and finally transmit them to the data acquisition unit through an RS485 interface. The data acquisition system is powered by an LM2596 power chip, with an STM32F103RCT6 as the processor and peripherals including a MAX485 chip and a relay control module.

[0028] The sound and light alarm system uses a QWH35T alarm horn, which can output a maximum sound level of 123dB. The alarm horn maintains its alarm action until the operator turns it off, ensuring the effectiveness of the QWH35T alarm horn. It uses red, orange, yellow, and blue LED lights as warning lights, which can provide different warnings based on the water level. The warning level of the four-color LED warning lights decreases sequentially from red, orange, yellow, to blue.

[0029] like Figure 2 As shown, the warning tide level module is powered by a wind-solar hybrid power supply system. The data acquisition system is at its core, controlling the audible and visual alarm system via I / O relays. It connects to the BeiDou communication system via an RS485 interface and to the 4G communication system via a TTL interface. When a command is issued from the backend, the 4G communication system sends the command back to the data acquisition system, which then controls the audible and visual alarm system to perform corresponding warning operations via I / O relays. When the 4G communication system has no signal, the command is sent through the BeiDou communication system.

[0030] like Figure 3 As shown, the data acquisition system consists of an STM32F103RCT6 processing chip, an LM2596 power supply chip, and a MAX485 conversion chip. The PA9 and PA10 pins of the STM32F103RCT6 processing chip are connected to pins 4 and 1 of the MAX485 chip, respectively, and the PA1 pin controls the transmit and receive functions of the MAX485 chip.

[0031] like Figure 4 As shown, the RDSS and RNSS modules inside the Beidou module unit are connected to the processing module, and it is equipped with an expansion main control board to facilitate secondary development according to requirements. At the same time, the module integrates an integrated built-in antenna.

[0032] like Figure 5 and Figure 6As shown, the warning tide monitoring module includes a monitoring box 1, which contains a first cavity 101 and a second cavity 102. The first cavity 101 is connected to the water area to be monitored via a pipe 103. The second cavity 102 is a semi-enclosed cavity, with no open space except for the inlet 201, effectively avoiding the influence of environmental factors such as atmospheric pressure, temperature, humidity, and suspended solids concentration changes. A dial wheel 104 is installed in the first cavity 101, and the dial wheel 104 is connected to a drive device. According to the settings, when the water level in the first cavity 101 rises, it represents a tide change. The rotation of the dial wheel 104 can adjust the first tide level. The water liquid in cavity 101 is introduced into the second cavity 102. Specifically, the dial wheel 104 is used to transfer the water liquid in the first cavity 101. A water level monitoring component 3 is installed in the second cavity 102, and a water tank 2 is installed in the second cavity 102. An inlet 201 is opened on one side of the top of the water tank 2. The inlet 201 and the dial wheel 104 are matched and used to introduce the water liquid in the first cavity 101 into the second cavity 102. Overflow holes 202 are opened on both sides of the water tank 2 to ensure that the water level in the first cavity 101 can only stay at the warning tide level. At the same time, the dial wheel 104 is activated to divert the water, mainly to use the second cavity 102 for secondary monitoring of the water level.

[0033] The water level monitoring component 3 includes a float 301, a hollow tube 302, and a micro switch touch plate 305. A positioning rod 303 is slidably installed inside the hollow tube 302. The float 301 is fixedly installed on the top of the positioning rod 303. A first spring 304 is fixedly connected between the positioning rod 303 and the bottom surface of the hollow tube 302. Second springs 306 are equidistantly arranged between the micro switch touch plate 305 and the top surface of the water tank 2. When the micro switch touch plate 305 is used... The water level monitoring sensor is triggered, and the communication system between the water level monitoring sensor and the entire warning tide monitoring module is connected. When the water level rises, the buoyancy of the float 301 caused by the rising water level is greater than the compression force of the first spring 304. The first spring 304 is stretched, and the positioning rod 303 moves upward with the float 301 until the float 301 touches the micro switch touch plate 305. The water level monitoring sensor sends a signal to the warning tide warning module, triggering the coordinated work between the internal units of the warning tide warning module.

[0034] The monitoring box 1 has a base 4 with a height adjustment component at its bottom. The base 4 includes two sets of side frames 401 and a lifting motor 402 fixedly connected between the two sets of side frames 401. A sliding assembly 5 is provided between the side frames 401 and the outside of the monitoring box 1. The sliding assembly 5 includes two sets of slide rails 501. A damper 502 is provided inside the slide rails 501. The telescopic rod end of the damper 502 is fixedly connected to the top of the side frame 401. The lifting motor 402 is provided to adjust the height of the monitoring box 1 in a timely manner, thereby ensuring that the water level inside the box is at the same level as the water level of the area to be monitored or within the set height difference range. The warning tide monitoring module and the warning tide early warning module are both equipped with matching signal data with the height difference, minimizing the error in the measurement results and effectively avoiding misjudgment of the results.
