[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figures 1-6 As shown, a pipeline impedance monitoring circuit includes:

[0037] An impedance measurement module is configured to send a signal to excite the piezoelectric sensor and measure the impedance of the piezoelectric sensor;

[0038] An ambient temperature acquisition module is configured to acquire ambient temperature.

[0039] The WIFI module is configured to send the signals collected by the piezoresistive impedance module and the ambient temperature acquisition module to a remote host computer.

[0040] The measurement and control module is configured to control the impedance measurement module to perform impedance measurement, control the WIFI module to perform wireless data transmission, and control the signal acquisition module to acquire ambient temperature.

[0041] The impedance measurement module is an AD5933 impedance measurement chip. The VIN and VOUT ports of the AD5933 impedance measurement chip are electrically connected to the piezoelectric sensor. The RFB port of the AD5933 impedance measurement chip is electrically connected to the VIN port through resistor R41, and the resistance of resistor R41 is 200KΩ.

[0042] The SCL port of the AD5933 impedance measurement chip is electrically connected to a 3.3V power supply via a 10KΩ resistor. The SCL port of the AD5933 impedance measurement chip is also electrically connected to the measurement control module. The SDA port of the AD5933 impedance measurement chip is also electrically connected to a 3.3V power supply via a 10KΩ resistor. The SDA port of the AD5933 impedance measurement chip is also electrically connected to the measurement control module.

[0043] The AD5933 is a high-precision impedance measurement chip manufactured by Analog Devices, integrating an on-chip frequency generator and a 12-bit, 1MSPS analog-to-digital converter (ADC). The signal generated by the frequency generator excites an external complex impedance. The response signal of the external impedance is sampled by the on-chip ADC and then processed by the on-chip DSP using a Discrete Fourier Transform (DFT). The DFT algorithm returns a real (R) data word and an imaginary (I) data word at each frequency. After calibration, the impedance amplitude and relative phase at each scan frequency point can be easily calculated. The calculations are performed off-chip using the contents of the real and imaginary part registers, and the register contents are directly read using the serial I2C interface. Compared with impedance analyzers such as the HP4294A, the AD5933 offers extremely high cost-effectiveness. Therefore, it was chosen as the core measurement component to complete the hardware design of a portable port machinery fatigue crack monitoring instrument. The signal conditioning circuit and the AD5933 peripheral control circuit were designed. The AD5933 control program and data processing program were written in C language and implemented in the STC microcontroller. The operation of the AD5933 and other parts is controlled through the I2C bus.

[0044] To perform a frequency scan, follow the sequence below:

[0045] Standby mode. Before issuing the start frequency scan command, a command to enter standby mode must be sent to the control register to put the device into standby mode. In this mode, the Vout and Vin pins are internally grounded.

[0046] Initialization Mode. This mode allows the user full control over the timing of entering frequency scan mode to meet the settling time requirements before measuring impedance. Issuing an initialization command to the control register at the start frequency will put the device into initialization mode. In this mode, the device excites the impedance at the programmed start frequency but does not perform measurements. After the required settling time, the user issues a start frequency scan command to the control register, thus entering frequency scan mode.

[0047] Frequency scan mode. The user enters this mode by issuing a start frequency scan command to the control register. In this mode, the ADC begins measurement after a certain number of settling time cycles.

[0048] The DDS output signal passes through a programmable gain stage to generate a peak-to-peak output excitation signal. The peak-to-peak output excitation voltage is selected by setting bits D10 and D9 in the control register and is provided on the Vout pin.

[0049] The impedance to be measured is connected between the Vout and Vin pins. Current flows through the impedance to be measured into the Vin pin, generating a voltage signal through a current-voltage amplifier. The user-selected feedback resistor value of the current-voltage amplifier and the gain of the PGA must ensure that the ADC operates within its linear range. The PGA allows the signal output to be amplified by 5x or 1x. After low-pass filtering, the signal is sampled by the ADC and then sent to the DSP for DFT calculation. The DFT calculation formula is:

[0050] The AD5933 has SCL and SDA pins and connects to the I2C bus as a slave device, controlled by the master device. Its default serial bus address is 0001101. The master initiates data transmission by establishing a start condition; the start condition requires the serial clock line SCL to be held high, the serial data line (SDA) to transition from high to low, and then data transmission occurs. The slave responds to the start condition by shifting in the next 8 bits, including a 7-bit slave address and an R / W read / write bit.

[0051] The slave device responds by pulling the data line low during the low period before the 9th clock pulse (acknowledgment bit) and keeping it low during the high period of this clock pulse. While the selected device waits to read or write data, all other devices on the bus remain idle. If the R / W bit is 0, the master writes data to the slave. If the R / W bit is 1, the master reads data from the slave. Data is sent via the serial bus in a sequence of 9 clock pulses: 8 bits of data followed by an acknowledge bit from either the master or slave. Data transitions on the data lines must occur during the low period of the clock signal and remain stable during the high period, as a low-to-high transition during a high clock period might be interpreted as a stop signal. If the operation is a write operation, the first data byte after the slave address is the command byte, informing the slave what to do next. It might be a simple instruction informing the slave that a block write is about to occur, or a register address informing the slave where to write subsequent data. Data can only flow in one direction as specified by the R / W bit, therefore commands cannot be sent to the slave during a read operation.

[0052] After all data bytes have been read or written, the stop condition is established. In write mode, the master pulls the data line high on the tenth clock pulse to set the stop condition. In read mode, the slave releases the SDA line during the low period before the ninth clock pulse, but the slave does not pull the data line low; this is called no-acknowledge. The master then pulls the data line low during the low period before the tenth clock pulse and then pulls the data line high during the tenth clock pulse to set the stop condition.

[0053] In a byte write operation, the master sends one byte of data to the slave. The byte write can be either a data byte written to a register address or a command operation. The command sequence for writing data to a register is as follows:

[0054] (1) The host sets the start condition on SDA.

[0055] (2) The master sends a 7-bit slave address and a write bit (0).

[0056] (3) The slave device at the corresponding address sets the bit on SDA to acknowledge.

[0057] (4) The host sends a register address.

[0058] (5) The slave device responds by setting a bit on SDA.

[0059] (6) The host sends a data byte.

[0060] (7) The slave device responds by setting a bit on SDA.

[0061] (8) The host sets the stop condition on SDA to end the process.

[0062] In a byte read operation, the AD5933 accepts a byte protocol to read a single byte of data from a register address, which is set by setting the address pointer. In this operation, the master reads one byte from the slave, and the command sequence is as follows:

[0063] (1) The host sets the start condition on SDA.

[0064] (2) The host sends the 7-bit slave address and the read bit (1).

[0065] (3) The slave device at the corresponding address sets the bit on SDA to acknowledge.

[0066] (4) The host receives a data byte.

[0067] (5) The slave device sets the no response bit on SDA (the slave device needs to check whether the master device has received the data).

[0068] (6) The host sets the stop condition on SDA to end the process.

[0069] The measurement control module is an STM32F405 chip. The PB8 and PB9 ports of the STM32F405 chip are electrically connected to the SCL and SDA ports of the AD5933 impedance measurement chip, respectively.

[0070] The ambient temperature acquisition module is an AD7190 chip. The AIN port of the AD7190 chip is electrically connected to the resistance temperature detector, and the other end of the resistance temperature detector is electrically connected to AGND.

[0071] The DIN, DOUT, SCLK, and CS ports of the AD7190 chip are each electrically connected to the measurement and control module via 22Ω resistors.

[0072] The measurement and control module is an STM32F405 chip. The PA7, PA6, PA5, and PA4 ports of the STM32F405 chip are electrically connected to the DIN, DOUT, SCLK, and CS ports of the AD7190 chip, respectively.

[0073] The AD7190 is a low-noise, complete analog front-end suitable for high-precision measurement applications, featuring a built-in low-noise, 24-bit Σ-Δ analog-to-digital converter (ADC). An on-chip low-noise programmable gain stage allows for direct input of small signals. The device can be configured with two differential inputs or four pseudo-differential inputs. An on-chip channel sequencer enables multiple channels, and the AD7190 performs conversions sequentially on each enabled channel. This simplifies communication with the device. An on-chip 4.92MHz clock can be used as the ADC's clock source; alternatively, an external clock or oscillator can be used. The output data rate can be varied from 4.7 Hz to 4.8 kHz. Two digital filter options are available. The choice of filter affects the root mean square noise and noise-free resolution, settling time, and 50 Hz / 60 Hz rejection when operating at the programmed output data rate. For applications requiring settling for all conversions, the AD7190 features zero latency. During continuous conversion acquisition, the RDY bit in the status register goes low after each conversion. If CS is low, the DOUT / RDY line will also go low when a conversion is complete. To read the conversion result, the user needs to write to the communication register to indicate that the next operation is to read the data register. After reading the data word from the data register, DOUT / RDY goes high. The user can read this register multiple times if needed. However, the user must ensure that access to the data register has ended when the next conversion is complete; otherwise, the new conversion word will be lost. If multiple channels are enabled, the ADC will continuously cycle through each enabled channel, performing one conversion on each channel in each cycle. Once the conversion result is obtained, the data register is updated immediately. The DOUT / RDY pin goes low each time a conversion result is available. The user can then read the conversion result while the ADC performs a conversion on the next enabled channel. If the DAT_STA bit in the mode register is set to 1, the contents of the status register will be output along with the conversion result each time a data read is performed. The status register indicates the channel corresponding to the conversion.

[0074] The Wi-Fi module is the E103-W11 Wi-Fi module. The RST, WAKE, TXD, RXD, CS, and MOSI ports of the E103-W11 Wi-Fi module are electrically connected to the measurement and control module via 22Ω resistors. The E103-W11 is a serial-to-Wi-Fi module with a small surface-mount package, operating in the 2.4-2.4835GHz frequency band. The module can use serial communication for data transmission and reception, lowering the barrier to entry for wireless applications. The main chip integrates all the hardware and software resources required for Wi-Fi and Bluetooth applications, supporting both AP and STA dual-role connections, and simultaneously supporting BLE low-power Bluetooth connections. The MCU, with a maximum operating speed of 240 MHz and built-in 512KB RAM, enables cloud connectivity.

[0075] The measurement and control module is an STM32F405 chip. The PC5, PC4, PA3, PA2, CS, and MOSI ports of the STM32F405 chip are electrically connected to the RST, WAKE, TXD, RXD, CS, and MOSI ports of the E103-W11WIFI module, respectively.

[0076] It also includes a power module, which provides power to the impedance measurement module, ambient temperature acquisition module, WIFI module, and measurement control module.

[0077] The power module output port provides power to the impedance measurement module, ambient temperature acquisition module, WIFI module, and measurement control module through the voltage regulation module;

[0079] The VIN and VOUT ports of the ADP160 chip are both grounded through multiple capacitors.

The IN port of the LT3042 chip is electrically connected to the positive terminal of the power module, and the OUT port of the LT3042 chip is connected to the VIN port of the ADP160 chip of the voltage regulation module.

[0081] Beneficial effects:

[0082] The integrated WIFI module transmits data from the impedance measurement and ambient temperature acquisition modules to a remote host computer in real time, enabling real-time acquisition of impedance data to monitor the degree of damage to the pipeline and ensure its normal operation.

[0083] The power module design utilizes ADP160 and LT3042 chips, employing voltage regulation and noise reduction technologies to ensure stable system operation at low power consumption. This design extends the equipment's lifespan and adapts to long-term operation requirements, making it particularly suitable for applications such as pipeline monitoring that require long-term operation and may be located in remote areas.

[0084] The circuit employs a modular design, enabling each functional module (impedance measurement module, temperature acquisition module, and WIFI module) to operate independently and work collaboratively. This design not only improves system maintainability but also allows for future expansion of other functions as needed, such as adding other sensor modules or improving wireless communication methods.

[0085] The LT3042 power supply noise reduction module effectively filters power supply noise and interference, ensuring circuit stability and measurement reliability. This is crucial for industrial pipeline monitoring, preventing errors caused by power supply noise.

[0086] The system design employs standardized interfaces and connection methods, reducing the complexity of wiring between different modules. This design not only saves space but also reduces the occurrence of malfunctions due to poor contact or tangled wiring.
