Description

Technical Field

[0001] The invention relates to the technical field of water level monitoring, and in particular to a water level remote online monitoring device. Background Art

[0002] During routine inspections, operators often encounter problems such as insufficient water levels in the reservoir or overflows when adding water. Since the reservoir is mainly used to store emergency fire water, keeping its water level within a reasonable design range is crucial to ensure the smooth operation of the equipment in the station.

[0003] However, the current water level monitoring mainly relies on manual labor. Specifically, the water storage room of the newly built substation adopts a floating rod mode for water level monitoring. The specific principle is to place a floating ball in the pool and hang a marker ball on the outer wall of the pool through a pulley combination. When the internal water level rises, the external marker ball will drop accordingly; conversely, if there is a lack of water inside, the external marker ball will rise. Although this method solves the problem of water level monitoring, it requires patrol personnel to squat on site to guard, which is both manpower-consuming and inefficient. Moreover, after field investigation, it was found that the pulley was exposed to the outdoors for a long time, exposed to the sun and rain, and was often corroded by rain, resulting in its function being impaired. In this way, in order to observe the water level, patrol personnel often need to climb a ladder to the roof, which not only increases the difficulty of work, but also poses certain safety hazards.

[0004] Therefore, it is urgent to realize real-time intelligent online monitoring of the water level in the reservoir, which can not only save labor costs and improve inspection efficiency, but also effectively ensure the safety of inspection personnel.

[0046] Embodiment 1

[0047] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in this field, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0048] Please refer to Figure 1-2 The embodiment of the present invention provides a water level remote online monitoring device, including a main controller 1, a communication module 2 and a water level monitoring module 3; wherein,

[0049] The communication module 2 and the water level monitoring module 3 are respectively connected to the main controller 1;

[0050] The water level monitoring module 3 is used to transmit a chirp signal to the water surface, capture the reflected signal, and mix the reflected signal with another synchronized chirp signal to obtain an intermediate frequency signal;

[0051] The main controller 1 is used to determine the water level according to the intermediate frequency signal, and send it to a remote end, such as a cloud server or a remote monitoring center, through the communication module 2, thereby realizing a remote online monitoring function of the water level.

[0052] In summary, the water level remote online monitoring device provided in the embodiment of the present invention realizes real-time, intelligent, and online monitoring of the water level of the reservoir by virtue of its highly integrated main controller 1, communication module 2, and water level monitoring module 3. This innovative design not only greatly saves labor costs and improves the efficiency of inspection work, but also effectively ensures the safety of inspection personnel, showing significant advantages and potential in large-scale promotion and application.

[0053] In one implementation of this embodiment, the water level monitoring module 3 is an ultra-high frequency millimeter wave radar.

[0054] This radar technology has shown significant advantages in the field of water level monitoring with its high precision and long-distance detection capabilities. By transmitting and receiving ultra-high frequency millimeter wave signals, the radar can accurately measure the distance between the water surface and the radar, and then accurately calculate the water level. Compared with traditional water level monitoring methods, ultra-high frequency millimeter wave radar has higher measurement accuracy and stronger anti-interference ability, and can work stably and reliably in various complex environments. Therefore, the use of ultra-high frequency millimeter wave radar as the water level monitoring module 3 further improves the performance and practicality of the water level remote online monitoring device of the embodiment of the present invention.

[0055] In one implementation of this embodiment, the main controller 1 is used to calculate the intermediate frequency signal according to the following formula to determine the water level:

[0056] ;

[0057] Wherein, d is the water level, c is the speed of light, Δf is the frequency difference of the intermediate frequency signal, and K is the frequency slope (frequency change rate) of the chirp signal.

[0058] It should be noted that the ranging technology of millimeter wave radar mainly relies on the principle of frequency modulated continuous wave (FMCW). The following is the detailed ranging process:

[0059] 1. Transmitting frequency modulated continuous waves: The radar's oscillator generates a signal whose frequency changes linearly with time. This signal is called a chirp signal. The frequency of the signal changes linearly from a lower frequency to a higher frequency over a period of time, forming a ramp-like frequency change.

[0060] 2. Signal transmission and reflection: The modulated signal is transmitted through the transmitting antenna, and when it encounters the target, the signal will be reflected back.

[0061] 3. Receiving and mixing: The reflected signal is captured by the receiving antenna and mixed with another synchronized chirp signal generated by the transmitter. Due to the different target distances, there will be a difference between the frequency of the reflected signal and the frequency of the transmitted signal. This frequency difference is called the intermediate frequency (IF) signal.

[0062] 4. Signal processing: By analyzing the frequency of the intermediate frequency signal, the distance of the target can be determined. This is because the frequency of the intermediate frequency signal is proportional to the distance of the target. Specifically, there is a linear relationship between the target distance and the frequency of the intermediate frequency signal, which can be solved by signal processing methods such as Fourier transform.

[0063] Distance calculation: Based on the measured IF signal frequency, the target distance can be calculated using the above formula.

[0064] In one implementation of this embodiment, the communication module 2 is designed to adopt 4G Cat1 long-distance wireless transmission technology and combine it with a communication method based on the MQTT (Message Queuing Telemetry Transport) protocol. This design choice fully considers the reliability, real-time performance and cost-effectiveness of data transmission.

[0065] As a mature wireless communication technology, 4G Cat1 technology has the advantages of wide coverage, stable signal, and fast transmission speed, and is very suitable for long-distance, high-reliability data transmission scenarios. The MQTT protocol is a lightweight message transmission protocol designed for low-bandwidth, unreliable or high-latency network environments, and can achieve real-time communication between devices with minimal overhead.

[0066] Combining these two technologies enables the communication module 2 in this embodiment to efficiently and stably transmit water level monitoring data from the main controller to the remote monitoring center. At the same time, the use of the MQTT protocol also ensures the real-time and reliability of data transmission, and ensures the integrity and accuracy of the data even in a complex and changeable network environment.

[0067] In summary, the use of 4G Cat1 long-distance wireless transmission technology and the communication module 2 based on the MQTT protocol not only improves the data transmission capability of the water level remote online monitoring device of the embodiment of the present invention, but also enhances its adaptability and reliability in practical applications.

[0068] In a detailed implementation of this embodiment, the water level remote online monitoring device is also integrated with a power supply module to provide a stable working power supply to ensure the continuous operation of the entire monitoring system. The power supply module is connected to the main controller 1 and is responsible for supplying power to all key components including the main controller, the communication module and the water level monitoring module.

[0069] In a specific implementation of this embodiment, the structure of the power supply module is further refined, specifically including two parts: a power management module 4 and a lithium battery 5 .

[0070] As the main energy storage unit, the lithium battery 5 has the advantages of high energy density, long cycle life, no memory effect, etc., and is a commonly used power solution in portable devices and remote monitoring devices. In this embodiment, the lithium battery 5 is connected to the power management module 4 through a specific interface to provide a stable DC voltage and current output.

[0071] The power management module 4 plays a crucial role. It is responsible for monitoring the power status of the lithium battery 5, including key parameters such as the remaining power, charging status, and battery health. At the same time, the power management module 4 also has an intelligent control function, which can automatically adjust the output voltage and current of the lithium battery 5 according to the instructions of the main controller 1 or the preset working mode to meet the power requirements in different working scenarios. In addition, the power management module 4 also has safety mechanisms such as overcharge protection, over-discharge protection, and short-circuit protection to ensure the safety and stability of the lithium battery 5 during use.

[0072] Finally, the power management module 4 is connected to the main controller 1 through a specific interface, realizing centralized management and control of the entire power supply system. The main controller 1 can send instructions to the power management module 4 as needed to adjust power supply parameters or query information such as battery status, thereby realizing comprehensive monitoring and management of the power supply system of the water level remote online monitoring device.

[0073] In summary, by integrating the power supply module consisting of the lithium battery 5 and the power management module 4, the water level remote online monitoring device in this embodiment is more reliable, efficient and intelligent in terms of power supply, providing a strong guarantee for the long-term stable operation of the equipment.

[0074] In the further optimization of this embodiment, the power supply module is further expanded, and a solar panel 6 is added as an auxiliary power source. This design is intended to enhance the self-sufficiency and environmental adaptability of the entire monitoring device, and is particularly suitable for monitoring scenarios that are difficult to access a stable power source or require long-term unattended operation.

[0075] The solar panel 6 is a device that can convert solar energy into electrical energy. It converts the photon energy in sunlight into electrical energy through the photoelectric effect and stores it in the lithium battery 5 connected thereto. In this embodiment, the solar panel 6 is connected to the power management module 4 through a specific interface to form a complete solar charging system.

[0076] The power management module 4 is not only responsible for monitoring the power status of the lithium battery 5, but also undertakes the task of managing the power input from the solar panel 6. It can intelligently adjust the charging current and voltage of the solar panel 6 according to the power status and charging requirements of the lithium battery 5 to ensure that the lithium battery 5 is charged in a safe and efficient state. In addition, the power management module 4 also has safety protection functions such as preventing overcharging and over-discharging to ensure the safety and reliability of the entire charging process.

[0077] By integrating the solar panel 6, the water level remote online monitoring device in this embodiment has a more diversified and sustainable energy supply. In the case of sufficient sunlight, the solar panel 6 can provide a continuous supply of electric energy to the lithium battery 5, extending the working time and service life of the device. At the same time, this design also reduces the dependence on external power sources, reducing the operating cost and environmental impact of the device.

[0078] In summary, the addition of the solar panel 6 significantly improves the energy self-sufficiency, environmental adaptability and sustainable development of the water level remote online monitoring device in this embodiment.

[0079] In a further refinement of this embodiment, an integrated housing is designed for the water level remote online monitoring device. This housing not only provides physical protection and support for the internal components, but also ensures the compactness and portability of the entire device.

[0080] The housing is made of durable materials, such as metal or high-strength plastic, to resist erosion and mechanical shock in harsh environmental conditions. Its design takes into account the needs of waterproof, dustproof and corrosion-resistant to ensure that the device can work normally in outdoor or humid environments.

[0081] Inside the housing, key components such as the main controller 1, communication module 2 and water level monitoring module 3 are carefully arranged and fixed. This layout not only ensures good connection and communication between the components, but also makes the entire device compact and light, making it easy to install and transport.

[0082] In addition, the housing may also be provided with necessary interfaces and openings, such as a power interface, a communication antenna interface, and a window for the water level monitoring module 3 to transmit and receive signals. The design of these interfaces and openings has been carefully considered to ensure that they can meet the functional requirements while maintaining the overall sealing and protection level of the housing.

[0083] In summary, by equipping the water level remote online monitoring device with an integrated housing, its reliability, durability and portability in practical applications are further improved. This housing not only provides good protection for the internal components, but also makes the entire device easier to install, transport and maintain.

[0084] In a further extension of this embodiment, an important component, a fixed bracket, is added to the water level remote online monitoring device. This design is intended to improve the installation stability and convenience of the device and ensure that it can operate stably in various application environments.

[0085] The fixing bracket is made of strong and durable materials, such as stainless steel or aluminum alloy, to withstand the pressure and impact caused by the device itself and external environmental factors. Its structural design fully considers the convenience and stability of installation, and may include adjustable fixing screws, mounting plates or hooks to adapt to different installation scenarios and needs.

[0086] By setting the housing on a fixed bracket, the entire water level remote online monitoring device can be easily installed on a wall, railing, column or other suitable supporting structure. This installation method not only simplifies the installation process, but also improves the stability and wind pressure resistance of the device, ensuring its normal operation under severe weather conditions.

[0087] In addition, the design of the fixed bracket may also take into account the maintenance and repair requirements of the device. For example, components that are easy to disassemble and install can be designed so that the housing can be easily removed for maintenance and replacement of internal components when necessary.

[0088] In summary, the addition of the fixed bracket provides a more stable and convenient installation method for the water level remote online monitoring device, further improving its reliability and practicality in practical applications.

[0089] In another implementation of this embodiment, the main controller 1 is functionally enhanced, especially by integrating a memory 7 therein. This design decision is intended to improve the data processing capability, data storage capacity and overall intelligence level of the water level remote online monitoring device.

[0090] As an important component of the main controller 1, the memory 7 is responsible for storing program instructions, data recording, and status information preservation. By integrating a high-capacity, high-reliability memory 7, it can be ensured that the main controller 1 can process the data from the water level monitoring module 3 in real time and accurately, and store it locally for subsequent analysis, processing, and uploading.

[0091] In addition, the memory 7 can also be used to store key resources such as device configuration information, historical data, and firmware upgrade packages. This enables the water level remote online monitoring device to automatically perform corresponding operations such as data reporting, fault alarm or system update according to preset rules or instructions without external intervention.

[0092] It is worth mentioning that the selection and configuration of the memory 7 needs to comprehensively consider multiple factors, including storage capacity, read and write speed, power consumption, data security, etc. Through reasonable design and selection, it can be ensured that the memory 7 can meet the system requirements while minimizing the impact on the overall power consumption and cost.

[0093] In summary, by providing the memory 7 in the main controller 1, a more powerful data processing and storage capability is provided for the water level remote online monitoring device, further improving its intelligence level and reliability in practical applications.

[0094] Although the terms such as main controller, communication module and water level monitoring module are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
