Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering monitoring technology, specifically relating to an intelligent rainfall and water level monitoring device. Background Technology

[0002] Water conservancy projects are crucial infrastructure for economic development, with small reservoirs playing a vital role in flood control, irrigation, and water supply. Small reservoirs have relatively low construction standards, are numerous, and widely distributed. Statistics show there are over 90,000 small reservoirs, accounting for 95.3% of all reservoirs. While some reservoirs rely on on-site inspections by monitoring personnel to monitor rainfall and water levels, less than 50% have automated rainfall and water level monitoring facilities, indicating a low rate of automation. Reservoirs equipped with automated rainfall and water level monitoring facilities experience high power consumption due to the deployment of cameras, rain gauges, and display screens that continuously show rainfall and water levels. This rapid power depletion, especially in remote areas where power supply is limited and unstable, can lead to insufficient power and reduced monitoring reliability when the monitoring devices are in high demand. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent rainfall and water level monitoring device to solve the problems of high power consumption and low monitoring reliability caused by insufficient power in existing rainfall and water level monitoring devices.

[0004] This utility model provides an intelligent rainfall and water level monitoring device to solve the above-mentioned technical problems. The device includes a power supply module, a display module, and rainfall and water level monitoring sensors. The power supply module provides operating power to the intelligent rainfall and water level monitoring device. It also includes a proximity trigger and a telemetry terminal. The proximity trigger detects whether a person is approaching the display module and sends a detection signal to the telemetry terminal. The telemetry terminal collects rainfall and water level information monitored by the rainfall and water level monitoring sensors. Only when the detection signal indicates that a person is approaching the display module, the terminal sends a command to the display module to activate the display module and sends rainfall and water level information to the display module for display.

[0005] Furthermore, the proximity trigger is an infrared sensor, a capacitive proximity sensor, or a millimeter-wave radar.

[0006] Furthermore, the rainfall and water level monitoring sensors include a water level gauge, a rain gauge, a first camera, a second camera, and a multi-element meteorological sensor. Each rainfall and water level monitoring sensor communicates with the telemetry terminal through an independent channel. The first camera is a fixed camera used to periodically capture images of the water level gauge. The second camera is a rotatable pan-tilt camera used to record video of the reservoir.

[0007] Furthermore, the power supply module includes a solar panel, a battery, and a mains power interface, which are used to provide the intelligent rainfall and water level monitoring device with three power supply methods: mains power, solar power, and battery power.

[0008] Furthermore, it also includes a two-way intercom module, which is used for real-time voice communication with the other party.

[0009] Furthermore, the power supply module, display module, proximity trigger, two-way intercom module, rainfall and water level monitoring sensor, and telemetry terminal are integrated and installed on the pole; among them, the water level gauge is a bubble-type water level gauge, and the air guide tube of the bubble-type water level gauge is laid along the conduit inside the pole. The main unit of the bubble-type water level gauge, the battery in the power supply module, and the telemetry terminal are installed in a protective enclosure.

[0010] Furthermore, during the integrated setup, the meteorological multi-element sensor is deployed on an L-shaped bracket fixed in the upper part of the pole.

[0011] Furthermore, during the integrated setup, the first camera is deployed above the crossbar support of the pole, and the second camera is deployed below the crossbar support of the pole.

[0012] Furthermore, it also includes a dual-channel communication module for communicating with the data center platform, with one channel using 4G / 5G / Ethernet communication and the other channel using BeiDou satellite communication.

[0013] Furthermore, the telemetry terminal's interfaces include an RS485 interface for communicating with a water level gauge, rain gauge, meteorological multi-element sensor, first camera, and second camera; an RS232 interface for communicating with the water level gauge, rain gauge, and meteorological multi-element sensor; a power interface for connecting to the power supply module; an interface for communicating with the display module; an interface for communicating with the proximity trigger; an RJ45 interface for accessing Ethernet, the first camera, and the second camera; and a USB interface for data interaction with the telemetry terminal. All interfaces are standardized.

[0014] The beneficial effects of the above technical solution are as follows: This utility model is an improved invention. A proximity trigger is set in the intelligent rainfall and water level monitoring device. The proximity trigger detects whether there are people near the display screen. Only when a person is detected approaching the display screen will the display screen be turned on, allowing the person to view the rainfall and water level information monitored by the rainfall and water level monitoring sensor on the display screen. This avoids the rainfall and water level monitoring device display screen from being constantly displayed, which can greatly reduce the power consumption rate of the rainfall and water level monitoring device. Under the same power supply, compared with the display screen being constantly displayed, the working time of the monitoring device is extended. This reduces the power supply requirements in areas with limited and unstable power supply and improves the reliability of rainfall and water level monitoring. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] This invention incorporates a proximity trigger in the intelligent rainfall and water level monitoring device, which activates the display module only when a person is detected approaching. This results in relatively low power consumption for the rainfall and water level monitoring device.

[0021] Device Implementation

[0022] This utility model provides an intelligent rainfall and water level monitoring device, which adopts a modular design and includes a telemetry terminal, a rainfall and water level monitoring sensor, a display module, a proximity trigger, a communication module, and a power supply module.

[0023] A proximity trigger is used to detect whether someone is approaching the display module and sends a detection signal to the telemetry terminal. The proximity trigger can be an infrared sensor, a capacitive proximity sensor, or millimeter-wave radar. The telemetry terminal collects rainfall and flood information monitored by the rainfall and flood monitoring sensors. Only when the detection signal indicates that someone is approaching the display module will it send a command to activate the display module and send rainfall and flood information to the display module for display. The display module can be an LED display screen or other display device.

[0024] After collecting various rainfall and water level information, the telemetry terminal of the intelligent rainfall and water level monitoring device transmits the monitored information to a remote data center platform for processing via a communication module. To avoid insufficient data transmission reliability, especially in the event of communication network failure under severe weather conditions, the communication module of this invention is a dual-channel communication module. One channel uses 4G / 5G / Ethernet communication, and the other channel uses BeiDou satellite communication. Preferably, the main channel is equipped with a 4G / 5G / Ethernet communication module, and the backup channel is equipped with a BeiDou satellite data transmission terminal to ensure data transmission reliability under severe weather conditions. During data transmission, the extreme value range and allowable rate of change parameters for each element can be set, automatically eliminating data that does not meet quality requirements and improving data transmission quality. A circular storage structure is adopted to ensure that data is not lost.

[0025] Due to unstable power supply in remote areas, this utility model's power supply module includes a solar panel, a battery, and a mains power interface to provide the intelligent rainfall and water level monitoring device with three power supply options: mains power, solar power, and battery power. The power supply module supplies power to the device through a charge / discharge controller, which includes a solar power interface, a load output port, an RS485 serial port, a battery interface, and a mains power interface. The load output port outputs the power supplied to the device, and the RS485 serial port outputs battery status information for monitoring battery status. Mains power prioritizes charging the battery, while solar power can be used to charge the battery during area power outages. The power supply can automatically switch; for example, solar power can be prioritized during good weather days, while mains power or battery power can be used at night or during inclement weather. In remote areas where there is a power outage at night, battery power can be used, improving power supply reliability.

[0026] The intelligent rainfall and water level monitoring system also includes a two-way intercom module. This module allows for real-time voice communication with personnel on the other end. For example, patrol personnel can observe the reservoir's video feed in real time and speak with reservoir management personnel on the other end, transmitting patrol information in real time. The two-way intercom module can use a microphone or speaker. Patrol personnel can also view reservoir management personnel through a camera and have one-way video communication with them.

[0027] To comprehensively monitor the reservoir environment, the rainfall and water level monitoring system includes a water level gauge, a rain gauge, a first camera, a second camera, and a multi-element meteorological sensor. The water level gauge can be a bubble level, pressure level, or radar level gauge to monitor the reservoir water level in real time. The rain gauge can be a tipping bucket level to monitor rainfall in real time. The multi-element meteorological sensor detects meteorological parameters of the reservoir in real time, including at least two of temperature, humidity, wind speed, and air pressure. The first camera is a fixed camera used to periodically capture images of the water level gauge, and water level information is identified based on these images. The first camera can be a bullet camera. The second camera is a rotatable pan-tilt camera used to record video of the reservoir, enabling monitoring of the overall reservoir conditions, floating debris, intrusion by personnel, and seepage behind the dam. Both the first and second cameras have infrared capabilities, enabling 24 / 7 monitoring, day and night. Each rainfall and water level monitoring sensor communicates with the telemetry terminal via an independent channel. For example, each water level gauge, rain gauge, and meteorological multi-element sensor has its own dedicated RS485 / RS232 interface, and each camera has its own dedicated RS485 or RJ45 interface to avoid bus conflicts. The water level gauge, rain gauge, and meteorological multi-element sensor support both timed data acquisition and reporting (e.g., hourly data acquisition and reporting) and event-triggered data acquisition and reporting (e.g., automatic data acquisition and reporting when the water level exceeds the limit).

[0028] The device also includes a lightning rod. The lightning rod, power supply module, display module, proximity trigger, two-way intercom module, communication module, rainfall and water level monitoring sensor, and telemetry terminal are integrated and mounted on the pole, enabling centralized control via the telemetry terminal. The display module is fixed to the pole with clamps.

[0029] like Figure 1 As shown, the intelligent rainfall and water level monitoring device includes a bubble level gauge (not shown in the figure), a tipping bucket rain gauge 1, a multi-element meteorological sensor 2, a microphone 3, an LED display screen 4, a protective enclosure 5, a proximity trigger 6, a bullet camera 7, a spherical pan-tilt camera 8 (capable of 360° rotation), a Beidou satellite data transmission terminal 9, a solar panel 10, a lightning rod 11, a telemetry terminal, and a battery. The air duct of the bubble level gauge is laid along the conduit inside the pole, and the air chamber is located underwater. The main unit of the bubble level gauge, the battery, and the telemetry terminal are housed in the protective enclosure 5. The tipping bucket rain gauge is mounted on an independent bracket on the pole, which extends horizontally 0.5m beyond the pole.

[0030] The pole structure is made of galvanized steel pipe with a diameter of Φ140mm and a wall thickness of 4mm, with a wind resistance rating of ≥12. The sampling device is arranged in a layered layout (from top to bottom).

[0031] The meteorological multi-element sensor 2 is deployed on an L-shaped bracket fixed in the upper part of the pole. Preferably, the L-shaped bracket and the pole are at the same height to avoid interference from the solar panel in wind direction detection. The lightning rod 11 is installed at the highest point of the pole. For example, the meteorological multi-element sensor 2 and the lightning rod 11 are installed at the top layer (4m high).

[0032] The middle layer (3.8m high) can hold 10 150W solar panels.

[0033] A horizontal bar is installed on the observation layer (3m high). A bullet-shaped camera 7 is deployed above the horizontal bar support of the upright, and a spherical pan-tilt camera 8 is deployed below the horizontal bar support of the upright. The observation layer also houses a tipping bucket rain gauge 1, a Beidou satellite data transmission terminal 9, and a microphone 3. Interaction layer (2.5m high): a suspended LED display screen; Equipment layer (2m high): a protective enclosure 5 is installed, with a proximity trigger 6 installed beneath the enclosure.

[0034] To improve the equipment compatibility of the intelligent rainfall and water level monitoring device, the device features a modular design, with each module using standardized interfaces for easy expansion and maintenance. Specifically, for example... Figure 2 As shown, the telemetry terminal uses standardized interfaces, including an RS232 interface for communication with water level gauges, rain gauges, and multi-element meteorological sensors; an RS485 interface for communication with water level gauges, rain gauges, multi-element meteorological sensors, the first camera, and the second camera; a power interface for connecting to the power supply module; an interface for communication with the display module (such as RS232 / RS485 interfaces); an interface for communication with proximity triggers (such as high / low level signal interfaces); an RJ45 interface for connecting to Ethernet, the first camera, and the second camera; and a USB interface for data interaction with the telemetry terminal (including downloading and upgrading software versions to and from the telemetry terminal). Wired interfaces, wireless interfaces, and pressure expansion interfaces can also be added as needed. The telemetry terminal also includes a built-in storage unit, a data processing unit, a digital display unit, and a wireless communication unit. The storage unit stores the received data, the data processing unit analyzes the received data and generates instructions, such as controlling the display module to turn on. The wireless communication unit is used to access 4G / 5G networks. The digital display unit displays the configuration parameters of the telemetry terminal.

[0035] like Figure 3As shown, the telemetry terminal acquires the detection signal from the proximity trigger and controls the display module to turn on when the detection signal indicates that someone is approaching the display module. The telemetry terminal also collects hydrological information, images, and video data, including water level, rainfall, and meteorological data, from water level gauges, rain gauges, multi-element meteorological sensors, and the first and second cameras. Through 4G / 5G / Ethernet / BeiDou networks, and in accordance with standard hydrological / water resources protocols, the collected data is automatically reported to the cloud-based data center platform for comprehensive analysis, achieving automated reservoir monitoring. This allows management personnel to focus on real-time data of the reservoir dam, providing a foundation and basis for reservoir management and scheduling, and supporting real-time emergency response decisions for reservoir safety. Furthermore, the device can be remotely configured with parameters, upgraded, and restarted. Modular and standardized design specifications improve the device's compatibility with other equipment.
