[0003] The existing hydrological monitoring devices have some shortcomings, which limit their effective application in mountainous areas: (1) Lack of autonomous early warning function: The existing technology lacks localized autonomous early warning threshold judgment and early warning function, which makes it difficult to realize the early warning function under extreme weather conditions or when the information remote transmission function is blocked. This limits its timeliness and reliability in disaster early warning. (2) Insufficient information collection and integration: The current monitoring devices are insufficient in integrating and collecting meteorological data, rainfall, water level, flow velocity and water quality information.

This hinders timely and effective early warning of flood and water quality risks in mountainous areas, and also makes it difficult to accurately assess the ecological safety of mountain rivers and the health risks to mountain residents.

[0053] It is worth noting that in this embodiment, the rain sensor 11 is connected to the first distributed data acquisition unit via a communication cable 111.

[0054] In this embodiment, the multi-parameter monitoring module 1 further includes:

[0055] The system includes a wireless signal transmitter 100 and a first distributed data acquisition unit 101. The wireless signal transmitter 100 is wirelessly connected to the graded early warning module 2.

[0063] In this embodiment, the main control microcontroller 21 is a RISC-V RV32IMAC chip.

[0064] In this embodiment, the graded early warning module 2 further includes an early warning screen 200 for displaying early warning information.

[0065] The early warning screen 200 can be set up in villages or residential areas near rivers to display the parameter information collected by the multi-parameter monitoring system and play an early warning role.

[0066] In this embodiment, the graded early warning module 2 may further include a command center 201, an SMS platform system 202, an early warning broadcast system 203, and a mobile client 204. The command center 201 uploads the discrimination results of the parameters obtained by the multi-parameter monitoring system from the graded early warning module 2 to the SMS platform system 202. The SMS platform system 202 sends river monitoring early warning information to the mobile client 204 to prepare nearby residents for early warning of flash floods and water pollution. The early warning broadcast system 203 receives the discrimination results and broadcasts them, playing the early warning information.

[0067] In this embodiment, the early warning broadcast system 203 can be set up in villages or residential areas near the river.

[0068] This invention features an automatic tiered early warning module based on multiple critical indicators such as rainfall, water level, and water quality. This module activates immediately when monitored data exceeds preset thresholds, eliminating the need for external information transmission. This ensures timely disaster warnings even when information is blocked or remote transmission is difficult, improving the timeliness and accuracy of flash flood warnings. By integrating real-time monitoring of key hydrological information such as rainfall, water level, flow velocity, water quality, and water temperature, as well as meteorological information such as air temperature, air pressure, atmospheric humidity, and light intensity, it achieves comprehensive understanding and early warning of risks such as mountain floods and river pollution, enhancing the accuracy of disaster prediction and response, and compensating for the lack of meteorological data in areas without available data. Furthermore, air temperature, air pressure, light intensity, and atmospheric humidity can be used for auxiliary early warning of natural disasters. Specific data on these parameters can further determine the probability of natural disasters occurring.

[0069] In this embodiment, the main control microcontroller 21 autonomously determines whether each water quality indicator in the water quality monitoring information exceeds the critical threshold through a preset critical threshold, and transmits the determination result to the command center 42.

[0070] See Figure 4 This illustrates in detail the process by which the tiered early warning module issues tiered warnings.

[0071] It should be noted that, Figure 4 The signal conditioning circuit is an integral part of the RISC-V RV32IMAC chip. That is, after the data from the multi-parameter monitoring module is input to the RISC-V RV32IMAC chip, the RISC-V RV32IMAC chip determines whether to issue an alert, and if so, what type of alert, based on the data from the multi-parameter monitoring module.

[0072] In this embodiment, the power supply module 3 includes:

[0073] The device includes a power generation unit, a charging protection circuit 35, an AC / DC power converter 36, and a battery pack 37.

[0075] In this embodiment, by adopting a multi-energy power supply method with a wind-solar-storage complementary architecture, the limitations of traditional hydrological monitoring equipment relying on a single power grid are overcome. This ensures uninterrupted operation of the equipment throughout the entire process, significantly improving the system's reliability and applicability. Considering the harsh conditions of mountainous environments, sustainable power supply methods such as solar and wind power are adopted, reducing the dependence of traditional monitoring systems on electricity and manual maintenance. Furthermore, the system has a long equipment operation and maintenance cycle, effectively reducing maintenance costs and ensuring long-term stable operation.

[0076] In this embodiment, the wind power generation device 31 includes high-strength carbon fiber blades, a hub, a speed increaser, a coupling, and a support. The wind power generation device 31 is connected to the battery pack 37 through a charging protection circuit 35 and an AC / DC power converter 36, and the generated electricity is stored in the battery pack 37.

[0077] In this embodiment, the solar power generation device 32 mainly includes a copper indium gallium selenide solar film, a solar controller, a micro inverter, a two-dimensional automatic rotating table, and a support. The solar power generation device 32 is connected to the battery pack 37 through a charging protection circuit 35 and an AC / DC power converter 36, and the generated electricity is stored in the battery pack 37.

[0078] In this example, the diesel generator set 33 mainly includes a diesel engine, a generator, a control box, a fuel tank, a starting and control battery, protection devices, and an emergency cabinet. The generated electricity is stored in the battery pack 37. The diesel generator 33 automatically starts only when the solar or wind power generation is less than 20% of the battery capacity and when there is continuous cloudy or rainy weather for more than 72 hours. The diesel generator 33 is characterized by its portability, stable power supply, high cost-effectiveness, and ease of operation and maintenance.

[0079] This application adds a diesel generator 33 to the power supply system, providing an emergency power source when solar and wind power are insufficient to supply the power required by the monitoring system in situations such as hail or extreme weather, which is of great significance for responding to extreme weather events in mountainous areas.

[0080] In this embodiment, the external power supply 34 is a backup power supply solution provided in this application. In the event of continuous flash floods, the area may enter a routine disaster monitoring phase. At this time, the reserved external power supply 34 can be activated to provide power to the monitoring system. The battery pack 37 is connected to the electronic components in the entire system via power supply lines.
