Description

Technical Field

[0001] This application belongs to the field of fuel regulator testing technology, and relates to a fuel regulator debugging device, specifically a fuel regulator metering module rapid debugging device and debugging method. Background Technology

[0002] Fuel regulators are used for the precise metering of fuel in the main combustion chamber and afterburner of aircraft engines to change or maintain the operating state of the aircraft engine, and are an important component of aircraft engines.

[0003] The metering module in the fuel regulator is the core component of the fuel regulator, mainly composed of an electro-hydraulic servo valve, a valve assembly, and a linear displacement sensor. The working principle of the fuel regulator metering module is as follows: The electro-hydraulic servo valve moves according to the received control command signal, which drives the valve assembly to move. The movement of the valve assembly changes the orifice area, thereby regulating the fuel flow. When the valve assembly moves, it drives the linear displacement sensor to move. The linear displacement sensor outputs the movement distance of the valve assembly and feeds it back to the testing device / controller. The testing device / controller performs closed-loop control based on the given electro-hydraulic servo valve command signal and the valve assembly movement signal fed back by the linear displacement sensor, thereby realizing closed-loop control of fuel metering.

[0004] As can be seen from the above, the function and performance of the metering module directly affect the performance indicators of the fuel regulator product.

[0005] The fuel regulator metering module debugging is mainly used to verify whether the function and performance of the metering module are consistent with the design goals. During the debugging process, it is necessary to provide a control signal to the electro-hydraulic servo valve and drive the electro-hydraulic servo valve, collect feedback signals from the linear displacement sensor, realize closed-loop control of the metering module, and then introduce fuel into the metering module to verify its function and performance.

[0006] Currently, fuel regulator metering module debugging equipment is usually shared with fuel regulator product debugging equipment. The fuel regulator product debugging equipment is usually a standard 38U cabinet, which integrates the drive module, signal conditioning module, signal acquisition module and other components required for fuel regulator debugging. It is not only large in size and expensive, but also has disadvantages such as being difficult to move, complicated wiring and complex to use. Summary of the Invention

[0008] A rapid debugging device for a fuel regulator metering module includes a host computer and a slave computer. The slave computer includes a data input / output module, an electro-hydraulic servo valve drive module, and a linear displacement sensor drive module. The host computer has a human-machine interface. Control data input through the human-machine interface is processed by the host computer to form control signals, which are then output to the data input / output module. The data input / output module then sends the control signals to the electro-hydraulic servo valve drive module, which outputs drive signals to the electro-hydraulic servo valve of the fuel regulator metering module based on the control signals. The linear displacement sensor drive module collects feedback signals from the linear displacement sensor of the fuel regulator metering module, calculates them, and outputs the corresponding differential ratio and signal to the data input / output module.

In the instruction set module program, the user-input position instruction set data is transformed into the corresponding control signal of the lower-level electro-hydraulic servo valve drive module, and communicated to the lower-level machine, which then outputs the corresponding voltage signal.

[0011] Furthermore, the lower-level machine uses an NI-PXIE industrial computer connected in series with a signal isolator, and the electro-hydraulic servo valve drive module and the linear displacement sensor drive module are connected in parallel at the back end of the signal isolator; the NI-PXIE industrial computer receives the control signals from the instruction-given module through the TCP / IP communication protocol, and outputs the control signals through the PXIE-4322 voltage output board inside the NI-PXIE industrial computer.

[0012] Furthermore, after receiving the electro-hydraulic servo valve control signal isolated by the signal isolator, the electro-hydraulic servo valve drive module outputs the corresponding electro-hydraulic servo valve drive signal to drive the fuel regulator metering module to the desired position.

[0013] Furthermore, the linear displacement sensor drive module outputs the linear displacement sensor drive signal of the fuel regulator metering module. The linear displacement sensor of the fuel regulator metering module senses the movement of the valve assembly. The linear displacement sensor drive module collects the VA and VB signals output by the linear displacement sensor, calculates them through internal circuitry, and outputs the linear displacement sensor differential ratio and signal to the signal isolator of the lower-level machine. After processing by the signal isolator, the signal is acquired by the PXIE-4481 voltage acquisition board in the NI-PXIE industrial computer.

[0014] A method for rapid commissioning of a fuel regulator metering module, using the aforementioned rapid commissioning device for a fuel regulator metering module, includes the following steps: S1, input control commands into the host computer; S2, the host computer checks whether the parameters are valid; if so, it proceeds to the next step.

[0026] Example 1: A rapid debugging device for a fuel regulator metering module includes a host computer and a slave computer. The slave computer includes a data input / output module, an electro-hydraulic servo valve drive module, and a linear displacement sensor drive module. The host computer has a human-machine interface. Control data input through the human-machine interface is processed by the host computer to form control signals, which are then output to the data input / output module. The data input / output module then sends the control signals to the electro-hydraulic servo valve drive module, which outputs drive signals to the electro-hydraulic servo valve of the fuel regulator metering module based on the control signals. The linear displacement sensor drive module collects feedback signals from the linear displacement sensor of the fuel regulator metering module, calculates them, and outputs the corresponding differential ratio and signal to the data input / output module. The data input / output module sends the differential ratio and signal, along with the collected electro-hydraulic servo valve control signal, back to the host computer. The host computer performs closed-loop control based on the control signals and feedback signals.

[0027] The host computer includes an instruction setting module, a data acquisition module, a parameter adjustment module, and a signal display module. The instruction setting module recognizes the input from the human-machine interface and converts it into the position control signal required for testing the fuel regulator metering module. The data acquisition module filters the communication signal parameters sent from the slave computer to the host computer, converts electrical signals to physical signals, and displays the processed signals. The parameter adjustment module is used to adjust the closed-loop control algorithm parameters of the entire debugging device. The signal display module displays the data processed by the data acquisition module as a numerical-time curve waveform.

[0028] The instruction set module receives decimal data input by the user, which represents the desired actuation position of the fuel regulator metering module. In the instruction set module program, the user-input position instruction set data is transformed into the corresponding control signal of the lower-level electro-hydraulic servo valve drive module, and then communicated to the lower-level machine, which outputs the corresponding voltage signal.

[0029] The lower-level machine uses an NI-PXIE industrial computer connected in series with a signal isolator. The electro-hydraulic servo valve drive module and the linear displacement sensor drive module are connected in parallel at the back end of the signal isolator. The NI-PXIE industrial computer receives the control signals from the instruction-given module through the TCP / IP communication protocol, and outputs the control signals through the PXIE-4322 voltage output board inside the NI-PXIE industrial computer.

[0030] After receiving the electro-hydraulic servo valve control signal isolated by the signal isolator, the electro-hydraulic servo valve drive module outputs the corresponding electro-hydraulic servo valve drive signal to drive the fuel regulator metering module to the desired position.

[0031] The linear displacement sensor driver module outputs the linear displacement sensor drive signal from the fuel regulator metering module. The linear displacement sensor of the fuel regulator metering module senses the movement of the valve assembly. The linear displacement sensor driver module collects the VA and VB signals output by the linear displacement sensor, calculates them through internal circuitry, and outputs the linear displacement sensor differential ratio and signal to the signal isolator of the lower-level machine. After processing by the signal isolator, the signal is acquired by the PXIE-4481 voltage acquisition board in the NI-PXIE industrial computer.

[0032] A method for rapid commissioning of a fuel regulator metering module, using the aforementioned rapid commissioning device for a fuel regulator metering module, includes the following steps: S1, input control commands into the host computer; S2, the host computer checks whether the parameters are valid; if so, it proceeds to the next step. S3, Start Test. The host computer sends a control signal to the slave computer, and the slave computer directly controls the fuel regulator metering module. S4, the lower-level machine collects data from the fuel regulator metering module; S5: After the host computer obtains the data collected by the slave computer, it performs data processing. S6 displays data on the host computer; S7, test complete.

[0033] In S5, when the host computer processes data, it performs closed-loop control based on the position command retrieval signal and the LVDT differential ratio signal. During use, the P parameter, I parameter and D parameter are adjusted in the host computer according to the steady-state and dynamic indicators of the closed-loop control to achieve the desired effect.

[0034] Example 2: The control signals required by the fuel regulator metering module are input into the host computer's human-machine interface. The slave computer receives the control signals via TCP / IP communication protocol. The data input / output module in the slave computer executes the output of the control signals and collects them back. The electro-hydraulic servo valve drive module outputs the corresponding electro-hydraulic servo valve drive signal according to the control signal, driving the electro-hydraulic servo valve to move the valve assembly. The linear displacement sensor is driven by the linear displacement sensor drive module. When the electro-hydraulic servo valve moves the valve assembly, the linear displacement sensor senses the displacement of the valve assembly and outputs the corresponding sensor feedback signal. The linear displacement sensor drive module collects the linear displacement sensor feedback signal, processes and calculates it, and outputs the corresponding differential ratio signal to the data input / output module. The data input / output module collects the differential ratio signal and the electro-hydraulic servo valve control signal and communicates them to the host computer via TCP / IP communication protocol. The host computer performs closed-loop control based on the control signal and feedback signal.

[0035] The above process completes the debugging of the fuel regulator metering module.

[0036] The block diagram of the testing device described in this invention is shown below. Figure 1 As shown.

[0037] The host computer interface is attached. Figure 2 As shown, it mainly consists of an "instruction setting module, data acquisition module, parameter adjustment module, and signal display module".

[0038] The instruction-giving module is used by the user to input the position control signals required for testing the fuel regulator metering module; The data acquisition module performs filtering, electrical signal to physical signal conversion, and other operations on the communication signal parameters sent from the lower-level machine to the upper-level machine. It then displays the processed signals to monitor the output status of command signals and the acquisition of LVDT feedback signals. The parameter adjustment module is used to adjust the closed-loop control algorithm parameters to achieve on-demand adjustment of the closed-loop control index of the fuel regulator metering module position; The signal display module displays the data processed by the data acquisition module in a numerical-time format as a curve waveform, making it easy for users to observe the experimental process data and intuitively display the closed-loop control status.

[0039] See attached hardware block diagram of the lower-level machine. Figure 3 As shown, it consists of four parts: an NI-PXIE industrial computer, a signal isolator, an electro-hydraulic servo valve drive module, and a linear displacement sensor drive module.

[0040] The NI-PXIE industrial PC includes a PXIE-1082 chassis, a PXIE-8822 embedded controller, a PXIE-4322 voltage output board, and a PXIE-4481 voltage acquisition board. The PXIE-8822 embedded controller supports TCP / IP communication and runs lower-level control software and a real-time operating system. The PXIE-4322 voltage output board outputs a (-10 to +10)V voltage signal with a sampling rate of 250kS / s, a maximum output frequency, and a 20mA current drive capability, meeting the control signal input requirements of the electro-hydraulic servo valve drive module. The PXIE-4481 signal acquisition board has a voltage acquisition range of (-10 to +10)V, meeting the LVDT differential ratio and signal acquisition requirements of the linear displacement sensor drive module. Signal isolators isolate input and output signals to ensure that the input and output signals are clean and free of noise and interference signals; The electro-hydraulic servo valve drive module receives the control command signal processed by the signal isolator and outputs the corresponding electro-hydraulic servo valve drive signal to drive the electro-hydraulic servo valve to move to the corresponding position. The linear displacement sensor driver module outputs a linear displacement sensor drive signal with specifications of 3Vrms and a 3000Hz sine wave excitation signal. It acquires the VA and VB signals output by the linear displacement sensor, calculates them through internal circuitry, and outputs the linear displacement sensor differential ratio and signal to a signal isolator. After processing by the signal isolator, the signal is acquired by the PXIE-4481 voltage acquisition board in the NI-PXIE industrial computer.

[0041] The specific working process of the device is as follows: When the device is running, a position control signal is given in the instruction-giving module of the host computer according to the test requirements of the fuel regulator metering module. The PXIE-8822 embedded controller in the lower-level NI-PXIE industrial computer receives control signals from the upper-level computer via TCP / IP communication, and further transmits the control signals to the PXIE-4322 voltage output board through the PXIE bus in the PXIE-1082 chassis to output control signals. The lower-level signal isolator receives the control signal output from the PXIE-4322 voltage output board in the lower-level PXIE industrial control computer, performs isolation processing, and then transmits it to the electro-hydraulic servo valve drive module. The lower-level machine's signal isolator collects the isolated control signal, which is then transmitted to the PXIE-4481 voltage acquisition board in the lower-level machine after further isolation. The lower-level electro-hydraulic servo valve drive module receives the isolated control signal and outputs the corresponding electro-hydraulic servo valve drive signal to drive the electro-hydraulic servo valve to move to the corresponding position. The electro-hydraulic servo valve drives the valve assembly to move. The lower-level machine's linear displacement sensor drive module outputs a linear displacement sensor drive signal. The linear displacement sensor senses the movement of the valve assembly. The linear displacement sensor drive module collects the VA and VB signals output by the linear displacement sensor, calculates them through internal circuitry, and outputs the linear displacement sensor differential ratio and signal to the lower-level machine's signal isolator. After processing by the signal isolator, the signal isolator is used to acquire the voltage by the PXIE-4481 voltage acquisition board in the lower-level machine. The host computer reads data from the slave computer via TCP / IP communication, and displays the position command retrieval signal and the LVDT differential ratio and signal output by the slave computer in the host computer's data acquisition module; The host computer performs closed-loop control based on the position command feedback signal and the LVDT differential ratio signal. During use, the P parameter, I parameter and D parameter can be adjusted in the host computer according to the steady-state and dynamic indicators of the closed-loop control to achieve the desired effect.

[0042] Example 3: The present invention will now be described in detail with reference to the accompanying drawings.

[0043] 1. Host computer software design 1.1 Host Computer Software Flow The host computer software process is as follows Figure 4 As shown. After inputting the control command, parameter confirmation is performed. The software automatically determines the validity of the input parameters. If the input parameters exceed or fall below the operating range of the fuel regulator metering module, the software will determine the parameters are invalid and prompt the user to re-enter them. If the parameters are valid, the test will begin. During the test, the host computer receives data sent by the slave computer via TCP / IP and performs data acquisition, analysis, and display functions. The acquired data, after processing, is used for both data storage and display, and for closed-loop control. When the steady-state and dynamic indicators of the closed-loop control are inconsistent with the expected values, the P, I, and D parameters are adjusted through the parameter adjustment module to achieve the desired effect.

[0044] 1.2 Instruction Setting Module The instruction set module receives decimal data input by the user, which represents the desired actuation position of the fuel regulator metering module. In the instruction set module program, the user-input position instruction set data is transformed into the corresponding control signal of the lower-level electro-hydraulic servo valve drive module. This signal is then transmitted to the lower-level PXIE-4322 voltage output board via TCP / IP communication, and the board outputs the corresponding voltage signal.

[0045] 1.3 Data Acquisition Module The data acquisition module performs filtering and electrical-to-physical signal conversion on the communication signal parameters sent from the lower-level machine to the upper-level machine. It then displays the processed signals to monitor the command signal output status and the acquisition of LVDT feedback signals. The specific scheme is as follows: The lower-level machine receives the control signal output by the upper-level machine signal instruction module (1.1.2) to drive the fuel regulator metering module to operate. The lower-level machine collects the control signal of the electro-hydraulic servo valve and the LVDT differential ratio and signal output by the linear displacement sensor drive module through the signal isolator module and the PXIE-4481 voltage acquisition module. It then transmits the data to the upper-level machine via TCP / IP communication. The data acquisition module in the upper-level machine collects the feedback signal and performs filtering and data processing.

[0046] The signal acquisition module consists of two parts: data reading and data processing. Data reading uses PXIE bus buffer data to ensure data accuracy; data processing removes interference and noise during the acquisition process to ensure data readability.

[0047] 1.4 Signal Display Module The signal display module displays the signal processed by the signal acquisition module in 1.1.3 in the form of a waveform curve, which facilitates the observation of the steady-state and dynamic indicators of the closed-loop control process.

[0048] 2. Lower-level machine design The lower-level machine consists of four parts: NI-PXIE industrial control computer, signal isolator, electro-hydraulic servo valve drive module, and linear displacement sensor drive module.

[0049] 2.1 NI-PXIE Industrial PC The NI-PXIE industrial computer receives the control signals output by the 1.1.2 signal setpoint module via the TCP / IP communication protocol, and outputs the control signals by the PXIE-4322 voltage output board inside the NI-PXIE industrial computer.

[0050] The NI-PXIE industrial computer includes the PXIE-1082 chassis, the PXIE-8822 embedded controller, the PXIE-4322 voltage output board, and the PXIE-4481 voltage acquisition board.

[0051] 2.2 Signal Isolator Signal isolators are primarily used to eliminate signal interference. Because devices may have potential differences due to different grounding, interference signals can exist within the devices. Signal isolators themselves provide isolation between input / output and power supply, thus eliminating interference signals.

[0052] The signal isolator receives the control signal output from the PXIE-4322 voltage output board in the lower-level PXIE industrial computer, isolates and processes it, and then transmits it to the electro-hydraulic servo valve drive module; the signal isolator receives the electrical signal output from the linear displacement sensor drive module in the lower-level PXIE computer, isolates and processes it, and then transmits it to the PXIE-4481 voltage acquisition board in the PXIE industrial computer for acquisition, receives the electro-hydraulic servo valve control signal for back acquisition, and finally transmits it to the upper-level (2) data acquisition module for data acquisition, processing and display via TCP / IP communication.

[0053] 2.3 Electro-hydraulic servo valve drive module (3) The electro-hydraulic servo valve drive module receives the electro-hydraulic servo valve control signal after isolation (2) and outputs the corresponding electro-hydraulic servo valve drive signal to drive the fuel regulator metering module to the desired position.

[0054] The electro-hydraulic servo valve drive module model is MKZ801B14, and its main technical parameters are as follows: Command input: ±10V voltage input; Output current: (-40~+40) mA current output, output accuracy ±0.1mA; Excitation signal: 300Hz, square wave; Nonlinearity: ≤1%.

[0055] 2.4 Linear Displacement Sensor Drive Module The linear displacement sensor drive module outputs the linear displacement sensor drive signal. The linear displacement sensor senses the movement of the valve assembly. The linear displacement sensor drive module collects the VA and VB signals output by the linear displacement sensor. After calculation by the internal circuit, it outputs the linear displacement sensor differential ratio and signal to the lower-level machine (2) signal isolator. After processing by the signal isolator, it is collected by the PXIE-4481 voltage acquisition board in the lower-level machine (1).

[0056] The AD598 is used to provide the excitation signal for the linear displacement sensor and to calculate the feedback signal of the linear displacement sensor.

[0057] The AD598 can generate a sinusoidal excitation signal of the corresponding frequency according to the excitation signal requirements of the linear displacement sensor, and output it after proportional and current amplification. The inductive signal is filtered and rectified before entering the AD598 for difference ratio and (VA-VB / VA+VB) calculation. The schematic diagram of the linear displacement sensor driver module is shown below. Figure 5 .

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should be covered within the protection scope of the present invention.
