Description

Technical Field

[0001] This invention belongs to the field of electrical signal processing technology, and in particular relates to a deep-water breakwater monitoring data processing circuit. Background Technology

[0002] Deep-water breakwaters are subjected to dynamic loads such as waves and currents over long periods. Monitoring parameters such as breakwater amplitude can identify abnormal vibrations (such as resonance or localized damage), preventing structural instability or failure due to cumulative effects. Current deep-water breakwater data monitoring typically relies on two independently designed circuit modules: one to capture vibration signals from the breakwater structure (such as vibration responses caused by wave impacts and structural deformation), collecting data through vibration sensors and triggering the monitoring process; and the other to perform timed monitoring, initiating data acquisition at preset intervals to ensure continuous monitoring. This separate design not only results in a bulky overall circuit structure, increasing the complexity, size, and power consumption of hardware deployment, but also requires additional design of inter-module collaborative control logic, increasing circuit integration difficulty, cost, and subsequent maintenance workload. Furthermore, it is difficult to adapt to the miniaturized and low-power deployment requirements of deep-water environments. Meanwhile, due to interference from deep-water environmental noise (non-target vibration signals generated by underwater current disturbances, wave impacts, marine biological activities, etc., as well as electromagnetic interference transmitted by seawater medium and thermal noise of the sensor itself), the trigger signal is easily distorted, thus falsely waking up the vibration monitoring module. This not only increases the amount of invalid data collected, wasting limited storage resources and communication bandwidth, but also frequently wakes up the dormant processing circuit, increasing system power consumption, and may even affect the accuracy and reliability of the health status assessment of deep-water breakwater structures.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0018] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Refer to the instruction manual. Figure 1 This invention proposes a deep-water breakwater monitoring data processing circuit, which includes a monitoring data acquisition unit, a monitoring data conditioning unit, a monitoring data processing unit, a wake-up unit, and a monitoring data output unit. The monitoring data acquisition unit is electrically connected to the monitoring data conditioning unit, the monitoring data conditioning unit is electrically connected to the monitoring data processing unit, the monitoring data processing unit is electrically connected to the monitoring data output unit, and the wake-up unit is electrically connected to both the monitoring data acquisition unit and the monitoring data processing unit. The monitoring data conditioning unit conditions the monitoring data acquired by the monitoring data acquisition unit and inputs the conditioned monitoring data into the monitoring data processing unit. The monitoring data processing unit preprocesses and extracts features from the conditioned monitoring data and outputs the results into the monitoring data output unit. The wake-up unit generates a wake-up signal based on the signal output by the monitoring data acquisition unit to wake up the monitoring data processing unit. It should be noted that the above-mentioned monitoring data processing unit uses Kalman filtering for real-time data preprocessing and feature extraction, which can simultaneously complete noise filtering and data completion. For problems such as sensor packet loss and interference from Gaussian noise, Kalman filtering can output smooth and complete preprocessed data. In addition, by integrating "filtering and noise reduction" with "feature extraction", there is no need to design an additional feature extraction module, which simplifies the design process and reduces the cost of processing circuits.

[0020] The monitoring data acquisition unit is the core front-end component of the deep-water breakwater monitoring system, collecting raw physical signals. Its core configuration includes a vibration sensor, installed at key locations on the breakwater body (e.g., the wave-facing side, the head, or the base). The vibration sensor can be, for example, a piezoelectric vibration sensor. This type of sensor achieves signal conversion based on the piezoelectric effect. Its core internal element is a crystalline material with piezoelectric properties (such as quartz crystal or piezoelectric ceramic). When mechanical vibration or pressure acts on the sensitive element of the piezoelectric vibration sensor, the lattice structure of the piezoelectric material deforms, leading to a redistribution and separation of internal charges, forming a weak electrical signal corresponding to external mechanical vibration parameters (such as amplitude, frequency, and acceleration). This directly converts mechanical energy into electrical energy. During operation, the vibration sensor accurately captures vibration characteristics from low to high frequencies. Simultaneously, the sensor's built-in signal conditioning circuit performs preliminary amplification and filtering of the generated weak electrical signal, effectively suppressing signal distortion caused by environmental electromagnetic interference, temperature drift, and other factors, ensuring that the output electrical signal has a good signal-to-noise ratio and stability.

[0021] The monitoring data conditioning unit includes an AD conversion module and a data storage and communication module. The AD conversion module converts the signal output by the monitoring data acquisition unit into a digital signal, and the data storage and communication module stores the digital signal and outputs it to the monitoring data processing unit. The monitoring data conditioning unit is a core intermediate component connecting the monitoring data acquisition unit and the monitoring data processing unit. It mainly consists of the AD conversion module and the data storage and communication module. The AD conversion module acts as a hub for converting analog signals to digital signals. For the continuous analog signal output by the monitoring data acquisition unit, it accurately converts the analog electrical signal corresponding to the physical quantity into a computer-recognizable digital signal through high-precision sampling, quantization, and encoding. The data storage and communication module has dual functions: local data storage and remote / near-end transmission. On the one hand, it uses a built-in storage unit (such as flash memory, SD card, etc.) to temporarily or permanently store the converted digital signal, avoiding data loss and facilitating subsequent tracing and retrieval. On the other hand, it uses standardized communication interfaces (such as RS485, Ethernet, Bluetooth, etc.) according to a preset communication protocol to stably and efficiently transmit the stored digital signal to the monitoring data processing unit, providing reliable data input support for subsequent data analysis, calculation, and decision-making.

[0022] The wake-up unit includes a wake-up signal generation unit, a buffer unit, and a wake-up signal output unit. The wake-up signal generation unit is electrically connected to the buffer unit, and the buffer unit is electrically connected to the wake-up signal output unit. The buffer unit is used to buffer and amplify the initial wake-up signal generated by the wake-up signal generation unit. The wake-up signal output unit is used to output the buffered and amplified initial wake-up signal to the enable interface of the monitoring data processing unit, thereby waking up the monitoring data processing unit.

The signal output from the monitoring data acquisition unit is connected to the input terminal of diode D2 through the IN terminal. The output terminals of diode D1 and diode D2 are connected to one end of resistor R2. The other end of resistor R2 is grounded. One end of resistor R2 is connected to the control terminal of switch K1. Power supply VDD2 is connected to one end of switch K1. The other end of switch K1 is grounded through current source I1. The other end of switch K1 is also connected to the control terminal of switch K2. One end of switch K2 is grounded, and the other end outputs OUT1.

[0024] Refer to the instruction manual. Figure 3 The buffer unit includes a current source I2, switches KM, K3, K4, K5, K6, and K7, resistors R3 and R4. Power supply VDD3 is connected to one end of current source I2. The other end of current source I2 is connected in series with switch KM and then connected to power supply VDD4. Power supply VDD4 is connected to the control terminal of switch K5. One end of switch K5 is connected to one end of switch K3, the control terminal of switch K3, and the control terminal of switch K4. The other end of switch K3 is connected to the other end of switch K4. One end of switch K4 outputs OUT2. The other end of switch K5 is connected to one end of switch K6 and one end of resistor R3. The other end of switch K6 and the other end of resistor R3 are connected to one end of switch K7 and one end of resistor R4. The other end of switch K7 and the other end of resistor R4 are both connected to OUT1.

[0025] Refer to the instruction manual. Figure 4The wake-up signal output unit includes switches K8, K9, K10, K11, and operational amplifier A1. OUT2 is connected to one end of switch K8, the control terminal of switch K9, and the control terminal of switch K11. The other end of switch K8 is connected to one end of switch K9 and the positive input terminal of operational amplifier A1. The control terminal of switch K8 is connected to the negative output terminal of operational amplifier A1. The other end of switch K9 is grounded, and the other end of switch K11 is grounded. One end of switch K11 is connected to the negative input terminal of operational amplifier A1 and one end of switch K10. The control terminal of switch K10 is connected to the positive output terminal of operational amplifier A1. The other end of switch K10 outputs the wake-up signal.

[0026] The working principle of the deep-water breakwater monitoring data processing circuit of this invention is briefly described below, in conjunction with the appendix to the instruction manual. Figure 2-4 First, power supply VDD1 charges capacitor C1 through resistor R1. When the voltage on capacitor C1 reaches a threshold, diode D1 conducts, generating a first driving voltage at the control terminal of switch K1. Simultaneously, the input terminal of diode D2 is connected to the signal output from the monitoring data acquisition unit. That is, when the monitoring data acquisition unit detects vibration of the deep-water breakwater, a vibration input voltage signal exists at the input terminal of diode D2. This vibration input voltage signal generates a second driving voltage at the control terminal of switch K1 through diode D2. The first or second driving voltage passes through a first buffer module composed of switches K1 and K2 and current source I1, generating an OUT1 signal proportional to the first or second driving voltage. This OUT1 signal is then buffered by a second proportional buffer module (which uses resistors R3 and R4 to adjust the OUT1 signal ratio) to generate an OUT2 signal. Finally, a wake-up signal output unit composed of operational amplifier A1 provides negative feedback and stable output to the OUT2 signal, eliminating fluctuations or noise and generating a reliable wake-up signal. The wake-up signal "awake" is input to the enable interface of the monitoring data processing unit. The monitoring data processing unit processes data based on the wake-up signal "awake" and outputs the data through the monitoring data output unit. This invention, through the two-stage buffering effect of the first buffer module and the buffer unit, can mitigate the distortion of the output signal of the monitoring data acquisition unit caused by underwater electromagnetic interference, thereby ensuring the reliability of the wake-up signal generated by the subsequent circuit. Furthermore, this invention utilizes capacitor C1 as a timer, integrating timed wake-up and vibration wake-up, which simplifies the circuit structure of the deep-water breakwater monitoring data processing circuit.
