Description

Technical Field

[0001] This utility model relates to the field of intelligent terminal technology for drainage pipe networks, and in particular to a convenient radar and ultrasonic integrated telemetry terminal. Background Technology

[0002] Existing drainage network flow monitoring requires Doppler flow meters and ground telemetry stations. The Doppler flow meter (hereinafter referred to as "flow meter") is installed at the bottom of the drainage pipe through a manhole. The ground telemetry station (hereinafter referred to as "telemetry station") includes a pole, outdoor protective box, solar power system, telemetry terminal, and other facilities, and is fixed to the ground near the manhole. The flow meter and telemetry station are connected by pipelines, and the flow meter is fixed with a special bracket. Such a monitoring station requires a large amount of auxiliary equipment, complex installation technology, and a cumbersome debugging process, and personnel working in the manhole pose a high safety risk. More importantly, limited by the flow meter's monitoring principle, the instrument can only monitor the flow when the pipe is full, while more often the drainage pipe is not full, resulting in significant errors in the monitoring results and failing to achieve accurate, real-time, and online monitoring.

[0003] In terms of post-installation maintenance, when used in drainage pipe networks, the flow meter probe is easily adhered to by impurities and corroded, requiring frequent maintenance. In rainwater pipe networks with high water levels and large flow rates, measurement accuracy is affected, and it has poor adaptability to complex pipe network layouts, potentially requiring significant pipeline modifications during installation, increasing construction difficulty and cost. Therefore, there is a need to provide a convenient integrated radar and ultrasonic remote sensing terminal. Utility Model Content

[0005] This utility model is achieved through the following solution:

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1As shown, a convenient integrated radar and ultrasonic telemetry terminal includes a hollow cavity upper shell 1 and a correspondingly connected lower shell 2. A radar level gauge 3 is installed on one side of the lower shell 2, and a radar flow meter 4 and an ultrasonic flow meter 5 are installed below the radar level gauge 3. A pressure level gauge 6 is installed at the bottom of the lower shell 2. A data acquisition module (not shown in the figure) is installed inside the upper shell 1. This invention also incorporates a communication module in the data acquisition module to facilitate data collection and processing. The data acquisition module is electrically connected to the radar level gauge 3, radar flow meter 4, ultrasonic flow meter 5, and pressure level gauge 6. This invention has the advantages of easy installation, non-contact measurement, high integration, stable operation, accurate measurement, and strong environmental adaptability. The radar flow meter 4 of this invention operates in the 24GHz ISM band and uses CW modulation, enabling real-time detection of water flow velocity information around the clock, unaffected by climate, temperature, surface water vapor, or pollutants in the water. The built-in high-efficiency data acquisition module ensures high accuracy of the measurement results. Furthermore, it employs a combination of measurement-based operation and sleep mode to save energy and reduce consumption.

[0020] The lower housing 2 of the hollow cavity structure includes a first cavity 21, a second cavity 22, and a third cavity 23. A mounting hole 7 is provided in the first cavity 21. The radar level gauge 3 is correspondingly disposed in the first cavity 21. The radar flow meter 4 and the ultrasonic flow meter 5 are sequentially disposed in the second cavity 22. The pressure level gauge 6 is correspondingly disposed in the third cavity 23. The first cavity 21 is a cuboid structure with one end open, and one end of the first cavity 21 is connected to the second cavity 22. The second cavity 22 is a trapezoidal structure, and the third cavity 23 is correspondingly connected to the other end of the second cavity 22. This utility model has a compact structure, combining radar and ultrasonic measurement technologies to achieve high integration, enabling accurate acquisition of flow velocity and level data. Furthermore, the modular layout of the three different cavities allows for electromagnetic isolation and zoned thermal management.

[0021] like Figure 2 As shown, the radar level gauge 3 includes a main unit 31, with a signal transmitter 32 at one end of the main unit 31, and several receivers 33 located below the signal transmitter 32. This radar level gauge 3 operates in the 80GHz ISM band and uses FMCW modulation, enabling real-time detection of water level information around the clock. It is unaffected by climate, temperature, surface water vapor, or pollutants in the water. It features a built-in high-efficiency data acquisition module to ensure high accuracy of measurement results. It also features non-contact measurement, safety and low loss, low maintenance, and is unaffected by sediment, allowing for all-weather operation, temperature-independent operation, and strong anti-interference capabilities.

[0022] One end of the radar level gauge 3 is connected to the mounting hole 7. A buckle 34 is also provided above the signal transmitter 32, and the buckle 34 is inserted into the inner side of the mounting hole 7. Several fixing posts 35 are provided on the outer side of the signal transmitter 32, and the fixing posts 35 are connected to the main unit 31. This invention improves structural strength and enhances environmental adaptability through multiple connection methods.

[0023] This novel ultrasonic flow meter 5 utilizes the Doppler effect of sound waves propagating in fluids. By measuring the Doppler frequency shift caused by the scattering of sound waves by tiny particles and bubbles in the fluid, it determines the fluid velocity. It features high precision, high reliability, and high intelligence. Simultaneously, the digital signal processing employs a Fast Fourier Transform algorithm to ensure the stability and reliability of the measurement data.

[0024] This practical data acquisition module employs a low-power data acquisition motherboard. Power management and chip configuration play a crucial role in reducing energy consumption and ensuring efficient system operation. The motherboard is equipped with a real-time clock chip, which provides a wake-up function to activate the system when needed, and also includes a low-power memory to cache critical status information. This minimizes energy consumption while maintaining the basic functions of the circuit board, supporting the device's rapid determination of whether to enter a low-power state. Furthermore, low-power power management reduces the energy consumption of various system components, allowing the device to operate for longer periods. This data acquisition module is also connected to a high-capacity lithium-ion battery pack. In practical use, the high-capacity lithium-ion battery pack consists of five 32650 lithium iron phosphate batteries and one SPC1550 capacitor. A capacitor is connected in parallel at the output of the lithium battery pack to effectively prevent fluctuations in battery output voltage caused by factors such as battery internal resistance and transmission lines.

[0025] In a specific embodiment, when the pipe is full, the ultrasonic flow meter 5 plays the primary role in flow measurement, while the radar flow meter 4 serves as a secondary measure. When the pipe is not full, the radar flow meter 4 is the primary measurer of flow, with the ultrasonic flow meter 5 playing a secondary role. Furthermore, this invention is highly adaptable to various drainage network scenarios, and can operate stably regardless of whether the sewage network contains impurities or corrosive liquids, or whether the rainwater network experiences large fluctuations in water level and flow velocity.

[0026] The specific structure, working principle, and working process of the data acquisition module, radar level gauge 3, radar flow meter 4, ultrasonic flow meter 5, and pressure level gauge 6 in this utility model are common knowledge and will not be described in detail here.

[0027] Although the technical solutions of this utility model have been described and enumerated in detail, it should be understood that modifications to the above embodiments or the adoption of equivalent alternatives are obvious to those skilled in the art. Such modifications or improvements made without departing from the spirit of this utility model are all within the scope of protection claimed by this utility model.
