Description

Technical Field

[0001] The present invention relates to the field of fluid transmission technology, and in particular to a deep learning-based wireless drive control method and device for a conductivity pump. Background Art

[0002] In cutting-edge technologies like microfluidic chips and implantable medical devices, precise fluid control plays a crucial role in device performance. Traditional conductivity pumps often utilize wired power supply drives. However, these external wires significantly increase the size of the device, severely hindering its development towards miniaturization and micro-miniaturization. Furthermore, wiring is extremely difficult in enclosed spaces or applications requiring frequent movement, such as implantable medical devices or sealed reaction chambers, significantly limiting the device's installation and flexibility. Furthermore, long-term use often leads to wire aging, causing equipment failures, increasing maintenance costs, and decreasing reliability, making it difficult to meet the demands of modern precision fluid control scenarios.

[0003] Although wireless energy transmission technologies such as electromagnetic induction and magnetic resonance have been gradually applied to the field of device driving in an attempt to solve the limitations of wired driving, these technologies generally have technical bottlenecks such as short transmission distance and low energy transmission efficiency. In practical applications, they cannot stably and efficiently provide sufficient energy for conductivity pumps.

[0004] In terms of power control, existing conductivity pump systems primarily rely on manually manipulated voltage parameter settings or open-loop voltage modulation. This control approach not only suffers from poor control accuracy, making it difficult to precisely regulate fluid flow and pressure, but also suffers from significant hysteresis. In fields such as microfluidic chemical analysis and biomedical drug delivery, where fluid manipulation precision and response speed are critical, these performance shortcomings severely restrict their application effectiveness and potential. Therefore, the development of fluid control systems with wireless actuation, adaptive regulation, and high dynamic response characteristics has become an urgent need to overcome current technological bottlenecks and promote innovation and development in related fields. Summary of the Invention

[0005] To address the shortcomings of the existing technology, the present invention provides a deep learning-based wireless drive control method and device for a conductivity pump. A microwave transmitter transmits a microwave signal of a specific frequency, and a microwave receiving module built into the conductivity pump converts the microwave energy into electrical energy to drive the conductivity pump, thereby resolving problems such as spatial limitations in a wired environment. The control unit adjusts the multi-parameter spatial position of the microwave receiving component to change the polarity coupling degree and path loss ratio between the transmitting and receiving components, thereby precisely regulating the received power and controlling the output pressure and flow of the conductivity pump. This method has important engineering practical significance.

[0006] In the far field, antennas radiate transverse electromagnetic waves, meaning the electric and magnetic field components are perpendicular to each other and to the direction of propagation. Based on the intensity of the electric field at a certain location at different times, it can be divided into linear polarization, circular polarization, and elliptical polarization. The polarization direction is related to the spatial position of the antenna. When the polarization direction of the receiving component is the same as that of the transmitting component, the receiving efficiency is the highest; when there is an angle, the received power will be significantly reduced due to polarization mismatch, and its efficiency attenuation follows the rule μ = μ. max cos 2 By dynamically adjusting the polarization direction, the mismatch loss can be suppressed to the theoretical minimum, thereby achieving global optimization of energy transmission efficiency.

[0007] During microwave transmission, the path loss formula is L(d) = k0 + k1d -n +k2e -αd , where d is the distance, n is the path loss exponent, and α is the attenuation coefficient. It can be seen that energy transmission efficiency is nonlinear. Traditional voltage regulation can only compensate for first-order linear errors in a fixed spatial configuration. Displacement modulation, by reconstructing spatial coupling parameters in real time, can directly correct higher-order nonlinear terms and significantly reduce its steady-state error.

[0008] Specifically, on the one hand, the present invention provides a wireless drive control method for a conductivity pump based on deep learning, which comprises the following steps:

[0013] S5. During the injection process, the dynamic parameter flow rate Q1 of the fluid in the microfluidic channel is continuously monitored. The microcontroller compares the dynamic parameter flow rate Q1 with the preset target value Q0 and calculates the relative error: ΔQ = |(Q1-Q0) / Q0| × 100%. When ΔQ exceeds the threshold range, closed-loop control is initiated. When ΔQ is within the threshold range, the process proceeds to step S6.

[0014] S6. If the flow fluctuation rate is less than the threshold, it is determined that the system has entered a stable state. The current angle α1 of the polarized antenna and the distance L1 between the microwave receiving component and the microwave transmitting component are recorded and used as initial parameters for the same working condition.

[0015] S7. After entering the stable state, if the ΔQ fluctuation rate is greater than the threshold, the control unit sends a closing electrical signal to the relay switch and repeats steps S3 to S6.

[0017] Preferably, in step S4, the microwave receiving component is connected to the conductivity pump and the specific steps of driving the conductivity pump to work are as follows: after the microwave is received by the coupling antenna, the high-frequency microwave energy is rectified into pulsating DC by a bridge rectifier after impedance matching and high-frequency filtering through the input filter network, and the filtering outputs a smooth DC voltage to the oscillation control unit. The oscillation control unit sets the pulse parameters and limits the current before driving the primary coil of the step-up transformer to form a high-frequency square wave AC signal.

[0018] Preferably, the power detection unit performs precision detection in step S1 as follows: the power detection unit verifies whether the output power precision error of the microwave transmitting component at the frequency point is less than ±5%, if so, proceeds to the next step; otherwise, replaces the polarized antenna of the microwave receiving component or performs equipment inspection.

When ΔL(k) ≥ 0, the dual-axis stepper motor drives the microwave transmitting component to move ΔL(k) toward the microwave receiving component through the slide rail; when ΔL(k) ≤ 0, the microwave transmitting component is driven away from the receiving component by |ΔL(k)|; after the movement is executed, the actual distance L(k) = L(k-1) + ΔL(k) is updated.

In a specific embodiment, the accuracy test performed by the power detection unit specifically verifies whether the output power accuracy error of the microwave transmitting assembly at a specific frequency point is less than ±5%. If so, the next step is performed. Otherwise, the polarized antenna of the microwave receiving assembly is replaced or the equipment is inspected. The frequency range of the microwave transmitting assembly is 1-10 GHz, with the 2.45 GHz ISM (Industrial, Scientific, and Medical Band) being preferred.

The oscillation control unit sets the pulse parameters through R1, R2 and C4, and drives the primary coil of the step-up transformer after current limiting by R3 to form a high-frequency square wave AC signal.

[0053] S5. During the injection process, the dynamic parameter flow rate Q1 of the fluid in the microfluidic channel is continuously monitored. The microcontroller compares the dynamic parameter flow rate Q1 with the preset target value Q0 and calculates the relative error: ΔQ = |(Q1-Q0) / Q0|×100%. When ΔQ exceeds the threshold range, closed-loop control is started. When ΔQ is within the threshold range, step S6 is entered.

[0054] In a specific embodiment, the specific process of closed-loop control is:

[0055] The microcontroller drives the motor to drive the microwave emitting component to perform intermittent reciprocating motion at a uniform distance in a straight line. The steady-state flow rate Q1 in the microfluidic channel is continuously monitored. The detection algorithm drives the microwave emitting component to move to the distance range corresponding to the required flow rate Q0. A collaborative control model of deep reinforcement learning and adaptive temporal convolutional network is used. The specific steps are as follows:

[0060] Preferably, ΔL(k) is used as the distance adjustment amount. When ΔL(k) ≥ 0, the dual-axis stepper motor drives the microwave transmitting component to move ΔL(k) toward the microwave receiving component through the slide rail; when ΔL(k) ≤ 0, the microwave transmitting component is driven away from the receiving component by |ΔL(k)|; after the movement is executed, the actual distance L(k) = L(k-1) + ΔL(k) is updated.

The current angle α1 of the polarized antenna and the distance L1 between the microwave receiving component and the microwave transmitting component are recorded and used as initial parameters for the same working condition.

[0062] In a specific embodiment, the volatility threshold in step S6 is 1%, and the volatility calculation formula is:

[0063]

[0064] Where k is the time point, N is the number of sampling cycles, Q1(i) is the flow rate at the i-th time point, is the average flow parameter of N cycles.

[0065] S7. After entering the stable state, if the ΔQ fluctuation rate is greater than the threshold, the control unit sends a closing electrical signal to the relay switch and repeats steps S3 to S6. Specific embodiments

[0067] This embodiment demonstrates the application of the microwave-driven conductivity pump of the present invention in a microbial culture system to achieve continuous and precise injection of a carbon source, thereby dynamically regulating the metabolic state of the microorganisms and improving culture efficiency and product consistency.

[0068] A dual stepper motor is installed on the guide rail in a cross-axis manner, and a turntable is installed above the motor, which is physically connected to the antenna in the transmitting component to fix the microwave receiving component.

[0069] First, connect the microwave transmitting component to a power source and use a spectrum analyzer to configure the directional antenna's beamwidth to a 30° half-power angle. Use the power detection unit installed on the microwave receiving component to verify that the transmitter's output power accuracy at the frequency point is <±5%. If not, replace the antenna or perform an equipment inspection.

[0070] The microchannel was prefilled with a charged ionic liquid containing a carbon source, the electrode pair impedance of the conductivity pump was measured, and the target flow rate Q0 = 6 μL / min was set for the microcontroller; the initial angle and distance were set according to empirical formulas; and the maximum output power of the microwave emission component was limited to 120 W and the electrode alarm threshold I = 500 mA.

[0071] The stepper motor is mechanically connected to the polarized antenna of the microwave transmitting assembly. The control unit drives the dual-axis stepper motor to perform a 720° clockwise rotation scan at an angular velocity of θ = 15° / s. The power detection unit collects the received signal strength indicator value in real time and records the angle-power mean correspondence data set {P(α)|α∈[0°,360°)}. The control unit performs Gaussian filtering on the angle-power data set and determines the angle α corresponding to the maximum received power using an extreme value detection algorithm. max; Drive the stepper motor to adjust the polarized antenna to α max ±0.25° accuracy range.

[0072] Upon determining that the coupling angle range has been reached, the control unit sends an electrical signal to the relay switch, connecting the microwave receiving assembly to the conductivity pump. The microwaves are received by the coupling antenna and then pass through the input filter network formed by L1 and C1 for impedance matching and high-frequency filtering. A bridge rectifier consisting of Schottky diodes D1-D4 rectifies the high-frequency microwave energy into pulsating DC, which is then filtered by L2 and C2 to output a smooth DC voltage. This DC voltage is supplied to the oscillator control unit based on a timing chip (NE555). This unit sets the pulse parameters using R1, R2, and C4. After current limiting by R3, it drives the primary coil of a step-up transformer, generating a high-frequency square wave AC signal. The stepped-up high-frequency voltage is then fed into a three-stage voltage multiplier consisting of D10-D14, C5-C9, and C6-C8. This voltage is then added to the output of a high-voltage DC signal, ultimately driving the microconductivity pump, which continuously injects the charged ionic liquid carbon source into the microbial reactor.

[0073] Flow and pressure sensors continuously monitor the dynamic parameters of the fluid within the microchannel (flow rate Q1) at a 60Hz sampling rate. The microcontroller compares the real-time data with the preset target value and calculates the relative error: ΔQ = |(Q1-Q0) / Q0| × 100%. When the threshold is exceeded, closed-loop control is initiated.

[0074] After steady state, if the ΔQ fluctuation is greater than 1%, the control unit drives the stepper motor to perform a 720° clockwise rotation scan at an angular velocity of θ = 15° / s. The stepper motor is mechanically connected to the polarized antenna of the microwave transmitting component; the received signal strength indicator value is collected in real time through the power detection unit, and the angle-power correspondence data set {P(α)|α∈[0°, 360°)} is recorded.

[0075] After the control unit performs Gaussian filtering on the angle-power data set, it determines the angle α corresponding to the maximum received power through the extreme value detection algorithm. max ; Drive the stepper motor to adjust the polarized antenna to α max The accuracy range is ±0.25°; on this basis, repeat the distance adjustment and steady-state determination.

[0076] During operation, if the current exceeds the alarm threshold, the system will automatically power off.

[0077] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
