Description

Technical Field

[0001] The present application relates to the technical field of oil and gas transportation, and in particular to a human-machine interactive stray current discharge method and system thereof. Background Art

[0002] In recent years, energy supply issues have become a key concern. To meet energy demand, pipeline networks have become increasingly large and complex. At the same time, the construction mileage of urban rail transit has also increased significantly. Urban rail transit leaks large amounts of stray current into the underground, causing serious problems with stray current interference. Stray current leaked from urban rail transit flows in and out of damaged oil and gas pipelines through the soil, causing drastic changes in the pipeline's ground potential, which in turn leads to severe electrochemical corrosion of the oil and gas pipelines. This stray current interference has an increasingly serious impact on the dynamics of oil and gas pipelines, threatening the safe operation of energy transmission systems. Therefore, there is an urgent need to develop a stray current drainage device to address this problem.

[0003] Currently, stray current drainage devices primarily employ highly reactive magnesium-aluminum alloys placed near pipelines, utilizing the cathodic protection principle of sacrificial anodes to protect oil and gas pipelines. However, this drainage solution only works when the pipeline ground potential is positive. Furthermore, stray current leaked from urban rail transit is a rapidly changing, dynamic current. Therefore, current methods may have limited capabilities and a lack of intelligence in managing dynamic stray currents.

[0004] Therefore, the poor ability of the stray current drain device in the related art to handle the dynamic stray current problem has become a problem that needs to be solved urgently. Summary of the Invention

[0036] The embodiment of the present application provides a human-computer interactive stray current discharge system, which can execute the human-computer interactive stray current discharge method provided in the embodiment of the present application. Figure 1 A schematic structural diagram of a human-computer interactive stray current discharge system provided in an embodiment of the present application.

[0037] like Figure 1As shown, the human-computer interactive stray current discharge system 001 includes at least one processor 011 and a memory 012 communicatively connected to the at least one processor; wherein the memory 012 stores instructions that can be executed by the at least one processor 011, and the instructions are executed by the at least one processor 011 so that the at least one processor 011 can execute the human-computer interactive stray current discharge method provided in an embodiment of the present application.

[0038] like Figure 2 As shown, in some embodiments, the human-computer interactive stray current discharge system includes: a DC-AC conversion module, a control module, a data acquisition and conversion module, a pulse width modulation drive module, a liquid crystal display module, a lightning protection module, a power supply module and a battery.

[0039] The input terminals of the DC / AC conversion module and the power module are both connected to the battery. The battery supplies power to the power module and the DC / AC conversion module.

[0040] The control module, data acquisition and conversion module (DC / AC conversion module), pulse width modulation drive module (PWM drive module), and LCD module are connected to the power module. The power module converts the DC voltage of the battery through various power chips into the DC voltage required by the control module, data acquisition and conversion module, PWM drive module, and LCD module.

[0041] The data acquisition and conversion module, pulse-width modulation drive module, and liquid crystal display module are each connected to corresponding interfaces of the control module. In some embodiments, the control module primarily comprises a control chip DSP28335 and its peripheral circuits. The SCI communication interface, A / D sampling interface, and EPWM interface of the control chip DSP28335 are connected to the liquid crystal display module, the data acquisition and conversion module, and the PWM drive module, respectively. This allows the control module to optimize the tube-to-ground potential collected by the data acquisition and conversion module, control the drive signal emitted by the PWM drive module, vary the output voltage of the DC / AC conversion module, and simultaneously transmit data collected by the data acquisition and conversion module to the liquid crystal display module, displaying various data statuses in real time.

[0042] In response to a selection operation of a target operating mode input on the standby interface, the liquid crystal display module is configured to display a first interface. The first interface includes a first input data control. The target operating mode includes one of a constant current mode, a constant voltage mode, and a constant potential mode.

[0043] In response to an operation of inputting preset standard data in the first input data control, collected data is displayed, wherein the collected data includes at least one of input current, input voltage, output current, output voltage and tube ground potential.

[0044] In the case of the target operating mode, the optimized control data is displayed periodically.

[0045] in,

[0046] In constant current mode, the collected data is sequentially processed through proportional-integral control and pulse-width modulation techniques to generate a drive control signal. This drive control signal is used to change the output signal of the DC / AC converter module. The difference between the output signal and the collected data is used to generate optimized control data.

[0047] In constant voltage mode, the collected data is sequentially processed through proportional-integral control and pulse-width modulation techniques to generate a drive control signal. This drive control signal is used to change the output signal of the DC / AC converter module. The difference between the output signal and the collected data is used to generate optimized control data.

[0048] In constant potential mode, optimized control data is derived from collected data using a proportional-integral control method and pulse-width modulation (PWM) based on a target optimization function. This generates a drive control signal. This drive control signal causes the DC / AC converter module to change its output signal. The optimized control data is derived based on the difference between the sum of the output signal and the grid voltage and the collected data.

[0049] In some embodiments, the DC / AC conversion module (DC / AC conversion module) can change the output voltage according to the control signal sent by the control module, so that the ground potential of the oil and gas pipeline is maintained within a reasonable range.

[0050] In some embodiments, the data acquisition and conversion module is composed of a voltage sampling and conditioning circuit and a current sampling and conditioning circuit. It can convert various collected analog voltage and current signals into digital signals and transmit the converted digital signals to the control chip of the control module. Thus, the data acquisition and conversion module is divided into voltage isolation sampling and conditioning and current sampling and conditioning, and can convert various analog voltage and current signals into digital signals that the control module can recognize, facilitating the control module to perform target optimization control.

[0051] In some embodiments, the PWM driver module, connected to the EPWM interface of the control chip DSP28335, can convert the PWM wave generated by the control chip into a drive signal that controls the on / off switching of the DC / AC converter module. In this way, the PWM driver module can control the on / off switching of the DC / AC converter module based on the control signal from the control module, thereby controlling the output voltage of the DC / AC converter module and achieving stray current control.

[0052] In some embodiments, the LCD module enables communication between the display and the control module, thus enabling human-machine interaction. A technician can click control buttons on the LCD to send control commands to the control chip via the SCI communication interface. Based on these commands, the control chip controls the DC / AC conversion module to operate in a set operating mode. Furthermore, the control chip transmits signals collected by the data acquisition and conversion module to the LCD module, which displays the operating status of the entire stray current drain device and the pipeline-to-ground potential in real time.

[0053] In order to adapt to complex application environments (such as the wild), in some embodiments, the lightning protection module is connected in parallel with the output terminal and the output terminal of the DC-AC conversion module. The main function of the lightning protection module is to provide protection.

[0054] In this way, the DC / AC converter module can change its output voltage based on control signals from the control module, maintaining the pipeline-to-ground potential of the oil and gas pipeline within a reasonable range. The control module can perform targeted optimization control based on the pipeline-to-ground potential collected by the data acquisition and conversion module, controlling the drive signal from the PWM drive module to change the DC / AC converter module's output voltage. Simultaneously, the data collected by the data acquisition and conversion module is sent to the liquid crystal display module, displaying various data statuses in real time. The data acquisition and conversion module is divided into voltage isolation sampling and conditioning and current sampling and conditioning, converting various voltage and current analog signals into digital signals that the control module can recognize, facilitating targeted optimization control. The PWM drive module can control the on and off state of the switching transistors in the DC / AC converter module based on control signals from the control module, thereby controlling the DC / AC converter module's output voltage and achieving stray current control. The liquid crystal display module enables communication between the display screen and the control module, enabling human-machine interaction.

[0055] Figure 3 This is a flow chart of a human-computer interactive stray current discharge method provided in an embodiment of the present application. Figure 3 As shown, in some embodiments, the human-machine interactive stray current discharge method includes the following steps:

[0056] S1, in response to an operation of selecting a target working mode input on a standby interface, displaying a first interface.

[0057] Standby interface, such as Figure 4aAs shown, it includes multiple controls. For example, it includes an input current text display control, an input voltage text display control, an output current text display control, an output voltage text display control, a tube-ground potential text display control, an input current floating-point display control, an input voltage floating-point display control, an output current floating-point display control, an output voltage floating-point display control, a tube-ground potential floating-point display control, a constant current mode switch button control, a constant voltage mode switch button control, a constant potential mode switch button control, and an oscilloscope button control.

[0058] In some embodiments, the human-computer interactive stray current draining method further includes: displaying a tube-to-ground potential waveform in response to a selection operation of an oscilloscope button control input on the first interface. For example, clicking the oscilloscope button control allows real-time viewing of the tube-to-ground potential waveform acquired by the data acquisition and conversion module.

[0059] Target working modes include: Figure 4b The constant current mode shown, Figure 4c The constant voltage mode shown and Figure 4d One of the constant potential modes shown. Clicking the corresponding operating mode switch button control can send instructions to the control module, thereby controlling the stray current drain device to operate in different modes. For example, the constant voltage mode is to make the DC / AC conversion module output a set voltage based on the input reference voltage. The constant current mode is to make the DC / AC conversion module output a set current based on the input reference current. The constant potential mode controls the output of the DC / AC conversion module based on the input reference pipe-to-ground potential through a target optimization algorithm, thereby controlling the pipe-to-ground potential of the oil and gas pipeline to the set pipe-to-ground potential.

[0060] When the target operating mode is constant current mode, Figure 4b As shown, the first interface includes multiple controls. For example, it includes an input current text display control, an input voltage text display control, an output current text display control, an output voltage text display control, a tube-to-ground potential text display control, an input current floating-point display control, an input voltage floating-point display control, an output current floating-point display control, an output voltage floating-point display control, a tube-to-ground potential floating-point display control, a constant current mode switch button control, a constant voltage mode switch button control, a constant potential mode switch button control, and an oscilloscope button control.

[0061] When the target operating mode is constant voltage mode, Figure 4cAs shown, the first interface includes multiple controls. For example, it includes an input current text display control, an input voltage text display control, an output current text display control, an output voltage text display control, a tube-to-ground potential text display control, an input current floating-point display control, an input voltage floating-point display control, an output current floating-point display control, an output voltage floating-point display control, a tube-to-ground potential floating-point display control, a constant current mode switch button control, a constant voltage mode switch button control, a constant potential mode switch button control, and an oscilloscope button control.

[0062] When the target working mode is constant potential mode, Figure 4d As shown, the first interface includes multiple controls. For example, the first interface includes an input current text display control, an input voltage text display control, an output current text display control, an output voltage text display control, a tube-to-ground potential text display control, an input current floating-point display control, an input voltage floating-point display control, an output current floating-point display control, an output voltage floating-point display control, a tube-to-ground potential floating-point display control, a constant current mode switch button control, a constant voltage mode switch button control, a constant potential mode switch button control, and an oscilloscope button control.

[0063] The first interface also includes a first input data control. The first input data control is used to input preset standard data. The preset standard data can be a preset threshold range. For example, a voltage range (-0.1V, 0.1V). Another example is a current range. Another example is a potential range.

[0064] S2, in response to the operation of inputting preset standard data in the first data input control, displaying the collected data.

[0065] The collected data includes at least one of input current, input voltage, output current, output voltage, and tube-to-ground potential. It is understood that the input current is displayed on the input current floating-point display control. The input voltage is displayed on the input voltage floating-point display control. The output current is displayed on the output current floating-point display control. The tube-to-ground potential is displayed on the tube-to-ground potential floating-point display control.

[0066] Exemplarily, when the preset standard data input into the first input data control is a voltage range (-0.1v, 0.1v), the first interface displays the input voltage value and the output voltage value.

[0067] S3, in the case of the target working mode, periodically displaying the optimized control data.

[0068] In some scenarios, the input voltage value and / or the output voltage value is not within the voltage range. By executing step S3, the stray current discharge can be changed according to the actual situation to achieve the control of the stray current and improve the service life of the oil and gas pipeline.

[0069] In some embodiments, the data acquisition and conversion module collects various voltage and current signals in real time and transmits these signals to the control chip of the control module. The control chip then optimizes the collected signals to generate PWM signals, which are then transmitted to the driver module via the EPWM interface. This PWM signal controls the DC / AC conversion module to output the corresponding voltage and current to manage stray currents. The control module also transmits the collected voltage and current signals to the display screen, which displays these data on the corresponding display controls after receiving the signals. The operating mode of the stray current drain device can be changed by clicking buttons on the display screen.

[0070] like Figure 6a As shown, in constant current mode, the collected data is sequentially processed through proportional-integral control and pulse-width modulation techniques to generate a drive control signal. The drive control signal is used to change the output signal of the DC-AC conversion module. The difference between the output signal and the collected data is used to generate optimized control data.

[0071] like Figure 6b As shown, in constant voltage mode, the collected data is sequentially processed through proportional-integral control and pulse-width modulation techniques to generate a drive control signal. The drive control signal is used to change the output signal of the DC-AC conversion module. The difference between the output signal and the collected data is used to generate optimized control data.

[0072] like Figure 6c As shown, in constant potential mode, optimized control data is derived from collected data using a proportional-integral control method and pulse-width modulation (PWM) based on the target optimization function to generate a drive control signal. This drive control signal causes the DC-AC converter module to change its output signal. The optimized control data is derived based on the difference between the sum of the output signal and the grid voltage and the collected data.

[0073] In some embodiments, in constant current mode, the optimized control data is a constant voltage. In constant current mode, the optimized control data is a constant current. In constant potential mode, the optimized control data is outputting a corresponding voltage and current based on the collected tube-to-ground potential value.

[0074] In some embodiments, the human-computer interactive stray current discharge method further includes:

[0075] S4, in response to receiving the driving control signal, changing the on and off state of the switch tube in the DC-AC conversion module, thereby controlling the output voltage of the DC-AC conversion module.

[0076] S5: confirm the optimized working mode based on the optimized control data.

[0077] S6: In response to the input selection operation of the optimized working mode, jump to the second interface.

[0078] The second interface is associated with the optimized working mode. Figure 5 As shown, taking the constant voltage mode as an example, you can select the constant current mode from the constant voltage mode interface. Alternatively, you can select the constant potential mode from the constant voltage mode interface. The changes between the constant current mode and the constant potential mode are similar to those of the constant voltage mode and will not be detailed here.

[0079] In some embodiments, the second interface includes a second input data control, and the human-computer interactive stray current discharge method further includes:

[0080] S7 , in response to the operation of inputting preset standard data in the second data input control, displaying the collected data.
