[0053] The following description and the drawings sufficiently illustrate specific embodiments of the invention to enable those skilled in the art to practice them.

[0054] It should be clear that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are only examples of systems and methods consistent with some aspects of the present invention as detailed in the attached claims.

[0056] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise specified, "plurality" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previously associated objects are in an "or" relationship.

[0057] The following will be combined with the attached Figure 1 -Attached Figure 7 , a Stirling generator starting method of a space anti-collision cylinder provided in an embodiment of the present application is introduced in detail.

[0058] See also Figure 1-7 The method of the embodiment of the present application may include the following steps:

[0059] Since the Stirling generator needs to push the working material into the high temperature zone when starting, it is easy to collide with the bar, causing damage to the generator and affecting its service life. Therefore, a Stirling generator anti-collision bar system based on the combination of software and hardware is studied and designed, which not only provides effective measures in hardware, but also can achieve prediction and prevention through software, which can greatly improve the safety and stability of Stirling power generation equipment and reduce accident risks and maintenance costs.

[0060] In order to solve one or more defects in the prior art, the system corresponds to a Stirling generator starting method with a spatial anti-collision cylinder, which controls the temperature and starting time of the generator by installing a temperature sensor and a timing controller on the generator.

[0061] S100, installing a monitor and a controller on a generator, wherein the generator has an actuator inside;

[0062] In the embodiment of the present application, the Stirling generator mainly includes sensors, shock-absorbing pads, buffers and other devices. The sensor can be installed in the cylinder, generator and other parts, the shock-absorbing pad can be installed in the cylinder, piston and other parts that are easy to impact, and the buffer can be installed in the generator, heat storage tank and other vulnerable parts.

[0063] Figure 2This is the sensor schematic diagram. The sensor is a very critical part of the hardware system and is used to collect monitoring data such as the attitude, position, and speed of the Stirling power generation equipment. In order to ensure the accuracy and reliability of the sensor, factors such as the accuracy, sensitivity, and stability of the sensor are considered when designing the sensor, and the appropriate sensor type and position are selected for layout. The sensors include: attitude monitoring sensors, such as the first attitude monitoring sensor 3, the second attitude monitoring sensor 4, the third attitude monitoring sensor 6, the fourth attitude monitoring sensor 5, and the fifth attitude monitoring sensor 7; in order to accurately measure the changes in the carrier attitude, the attitude monitoring sensor has two built-in high-precision single-axis inclination sensors. The attitude monitoring sensor adopts the differential measurement principle and installs two sensitive elements, namely two high-precision single-axis inclination sensors, on the same axis, which can improve the accuracy and low-temperature drift of the attitude monitoring sensor. The attitude monitoring sensor as a whole uses gravity acceleration as the measurement object. When the angle of the carrier changes, the internal mass sheet of the attitude monitoring sensor will tilt with gravity, causing the size of the capacitors on both sides to change. The current tilt angle is calculated by measuring the difference between the two. Since the direction of gravity acceleration g is always perpendicular to the ground, if the carrier is in a horizontal state, the gravity acceleration is projected on the plane as 0; similarly, when the carrier is tilted, there is an angle between gravity and the plane, then gravity will have a component on the horizontal plane, thereby measuring the state of the device. The sensors include: position sensors, such as a first position sensor 1 and a second position sensor 2; the position sensors are used to estimate the position of the engine under low switching frequency. The key lies in constructing a reasonable observer to estimate the back-EMF. The performance of the observer determines the performance of estimating the back-EMF, which in turn affects the performance of estimating the rotor position and speed. The analysis of the discretization error and back-EMF cross-coupling problems existing in the discretization process of the continuous domain model under low switching frequency is provided to realize position sensor control in non-weak magnetic zone and weak magnetic zone within the high-speed range, meet the operation requirements within the range of more than 10% of the rated speed, and improve the dynamic performance and anti-disturbance of the rotor position estimation. The sensors include: speed sensors, such as a first speed sensor 13, a second speed sensor 10, a third speed sensor 11, a fourth speed sensor 12, a fifth speed sensor 9, and a sixth speed sensor 8. Due to the complex internal electromagnetic relationship of the Stirling generator, the speed sensor is combined with the generator's unique dual-synchronous speed rotating coordinate system as a reference coordinate system to analyze the influence of the load active current on the speed estimation and the fact that fixed proportional and integral parameters cannot obtain excellent performance of the speed estimation of the Stirling generator under different working conditions, thereby overcoming the dynamic rapidity problem in speed measurement, realizing accurate real-time monitoring of the generator speed, and preventing the generator from hitting the cylinder during startup.

[0064] Figure 3It is a schematic diagram of the actuator principle. The actuator is a key part of the hardware system to control the movement and posture of the device. When designing the actuator, factors such as the dynamic response, control accuracy, and load capacity of the actuator are considered, and the appropriate actuator type and position are selected for arrangement. Its main structure includes: a runner 23, a cylindrical shell 16, a second rotor 17, and a first rotor 15; the second rotor 17 is placed on the left side of the generator, and the first rotor 15 is placed on the right side of the generator; the armatures of the cylindrical shell 16 and the runner 23 are independent of the second rotor 17 and the first rotor 15, and are separated by an air gap; the armature structures of the two motors of the cylindrical shell 16 and the runner 23 are exactly the same, that is, the number of slots is equal, the slot type is the same, and the armature winding is shared; in the structure of the second rotor 17 and the first rotor 15, the permanent magnet part and the electric excitation part should have the same electrode arc coefficient, and the center lines of the magnetic poles are aligned. The main structure of the actuator also includes a second coil spring 22 and a first coil spring 21. The second coil spring 22 and the first coil spring 21 are composed of a non-magnetic isolator, an outward-expanding magnetizer, an inward-expanding magnetizer, etc. They store energy when they are compressed or stretched, and release the energy when needed. This energy storage and release characteristic helps the generator maintain a stable working state when the load changes. The outward-expanding magnetizer and the inward-expanding magnetizer both extend toward the same end along the direction of the motor shaft. The outward-expanding magnetizer extends outward to expand into a circular ring shape, and the inward-expanding magnetizer extends inward to shrink into a cylindrical shape. The circular ring and cylindrical parts are called extension ends. The extension end has a space for placing an annular magnetic bridge. The annular magnetic bridge is fixed on the end cover and has a certain air gap with the extension end. The air gap between the annular magnetic bridge and the outward-expanding magnetizer is called an outer additional air gap, and the air gap between the annular magnetic bridge and the inward-expanding magnetizer is called an inner additional air gap. The main structure of the actuator also includes the first electrode bracket 14 and the second electrode bracket 18, the first electrode substrate 19 and the second electrode substrate 20, wherein the first electrode bracket 14 and the second electrode bracket 18 are used to support and fix the electrodes of the generator to ensure that the generator can run stably; the first electrode substrate 19 and the second electrode substrate 20 are used to support and connect the electrodes of the generator, and the electrodes are embedded with tangentially magnetized permanent magnets, and there are two permanent magnet sections to provide each pole flux to the air gap, and the magnetic potential of each rare earth permanent magnet provides each pair of poles. Therefore, the air gap magnetic density of the generator can be greatly improved, even exceeding the residual magnetism of the magnetic steel, and has a significant "magnetic concentration" effect. However, in order to avoid short circuits at the ends of the permanent magnets on the shaft side, non-magnetic bushings must be used to separate the permanent magnets from the shaft.

[0065] Figure 4It is the schematic diagram of the (main) controller. The controller is the key part of the hardware system to implement the control instructions generated by the software. When designing the controller, the computing power, communication capability, anti-interference capability and other factors of the controller are considered, and the appropriate controller type and position are selected for layout. The generator is the main component of the Stirling engine, which is mainly composed of the main winding and the auxiliary winding. The main winding and the auxiliary winding are wound separately on each stator pole. Its self-inductance changes with the relative position of the rotor, thus generating a rotating electromotive force. Especially when running at high speed, the induced electromotive force is large. The engine output voltage control can be achieved by adjusting the excitation current. The first single-chip microcomputer is a 32-bit ARM architecture microprocessor, which is mainly used to control the output current detection module, collect the output current of the load in real time, and shut down the inverter module when the load is overcurrent. The inverter module uses an inverter bridge, control logic and filter circuit to convert DC power (such as batteries, storage bottles, etc.) into AC power. This conversion process involves pulse width modulation (PWM) technology. By controlling the switching action of the switch tube, the DC voltage charges and discharges the inductor, so that the AC voltage is obtained at the other end of the inductor. The rectifier module is mainly composed of a matching network, an input low-pass filter, a rectifier diode, an output DC filter and a load, wherein the matching network is used to achieve impedance matching between the receiving load and the rectifier circuit. The input low-pass filter is used to suppress the higher harmonics generated by the rectifier diode to avoid the radiation waste of the higher harmonic energy through the receiving antenna, resulting in energy loss. The output DC filter suppresses the fundamental wave and harmonics, and reflects them back to the rectifier diode for re-rectification, thereby improving the rectification efficiency of the rectifier diode. The second single-chip microcomputer is also a 32-bit ARM architecture microprocessor, which mainly manages the power supply module, DC input voltage and current protection module, inverter drive module, output voltage detection module, speed detection module and generator speed regulation module of the system. The power supply module provides power supply voltage conversion to provide power supply for each module of the system. The speed detection module and the generator speed regulation module collect the voltage signal output by the speed sensor, calculate the current speed of the generator, and realize the speed regulation of the generator through closed-loop control. The regulating device mainly fine-tunes the speed of the engine according to the generator speed regulation module, thereby realizing precise control of the engine. The control unit includes a first single-chip microcomputer and a second single-chip microcomputer. The DC input voltage and current protection module is used to monitor and protect the voltage and current anomalies in the circuit. When the voltage or current exceeds the preset threshold, it can automatically cut off the circuit to prevent the system from being damaged due to current overload. The inverter drive module is mainly responsible for driving the inverter circuit corresponding to the inverter module to convert direct current DC into alternating current AC. The output voltage detection module is mainly used to monitor the changes in the output voltage in the circuit in real time to ensure that the voltage value is within the predetermined range to protect the system hardware circuit from overvoltage and undervoltage damage.

[0066] Figure 5It is the communication topology diagram of the system, which is mainly the topology diagram of the communication between the mother aircraft bus network and the child aircraft bus network through the 1553B bus. The 1553B communication bus used by the system is composed of a bus controller BC, a remote terminal RT and a bus transmission medium. The bus transmission medium can be bus A and bus B; the 1553B communication bus includes bus A and bus B, which are redundant backups for each other. The bus controller BC and the remote terminal RT share the main line part of the bus in parallel. The main line and the sub-line are coupled by transformers, and the sub-line and the 1553B device are also coupled by transformers. The 1553B communication bus system adopts a command / response transmission operation mode. When an instruction is issued by the bus controller BC, the remote terminal RT responds to the instruction, receives the instruction sent by the bus controller BC, or sends telemetry data to the bus controller BC. The remote terminal RT receives the instruction and parses the command word and data word in the instruction. The CPU processor can receive the instruction sent from the 1553B communication bus by regularly querying the specified memory address. During this process, the command information sent or received is used to control the timing and constant temperature start-up of the Stirling generator, greatly improving the safety and stability of the Stirling power generation equipment and reducing accident risks and maintenance costs.

[0067] In the communication bus, 1553B bus and Ethernet are used for transmission. DSP1 and DSP2 processors are used to collect temperature data of different parts of the generator and calculate the actual value of the temperature for power generation and startup of the generator equipment. UART is responsible for exchanging data between DSP1 and DSP2. FPGA is responsible for receiving and sending remote control commands and telemetry data transmitted on 1553B and Ethernet buses. Two Flashes are used to store program codes run by DSP1 and DSP2, PROM is used to store programs run by FPGA, and two SDRAMs are used to load programs of DSP1 and DSP2 in FLASH.

[0068] Figure 7: is a system structure diagram, which mainly includes a cylindrical shell 16, a first electrode bracket 14, a second electrode bracket 18, a generator electrode substrate 30, a generator symmetrical winding 50 and a generator rotor 40. Among them, the cylindrical shell 16 is the outer shell structure of the generator. It is a common shell structure form. It has the characteristics of small thickness, light weight, less consumables, good performance, etc. and is widely used in generators. Its function is to form a magnetic circuit and circuit for mutual electromagnetic induction to generate electromagnetic power; the first electrode bracket 14 and the second electrode bracket 18 are used to support and fix the motor bracket. The generator rotor 40 includes a second rotor 17 and a first rotor 15. Its function is to make the coil cut the magnetic flux line when the external mechanical force drives the generator symmetrical winding to rotate, so as to generate current inside the generator. The generator symmetrical winding 50 includes a main winding and an auxiliary winding. Its function is to form a multi-phase self-closed multi-branch circuit. It can induce current for two different pole pairs and can also serve as an excitation source to excite each other. In this way, two rotating magnetic fields with different pole pairs are forced to be generated, realizing the pole pair conversion function.

[0069] The generator electrode substrate 30 includes a first electrode substrate 19 and a second electrode substrate 20, which are used to support and connect the electrodes of the generator to ensure that the current can be transmitted smoothly, thereby driving the generator to operate normally. By studying the influence of the substrate thickness of the generator electrode substrate 30 on the motor performance, the reasonable position of the auxiliary magnetic pole and the reasonable thickness of the auxiliary magnetic steel are analyzed in detail, and the structure of the system is optimized; through actual testing, the performance influencing factors of the tangential magnetic steel permanent magnet AC generator with a pole pair number of 2 in the Stirling generator are verified and analyzed, and the performance of the 2-pole tangential magnetic steel permanent magnet AC generator when the rotor and stator length ratio Lr / Ls takes different values ​​is compared.

[0070] S200, the monitor obtains monitoring data of the generator and sends the monitoring data to the controller via 1553B communication.

[0071] The communication transmission protocol of the embodiment of the present application adopts the 1553B bus, which is a serial communication protocol used for data communication in the fields of aviation and aerospace. It is a bidirectional synchronous bus that can transmit digital data between two or more nodes. Its communication speed is as high as 1Mbps, and it has the characteristics of high reliability, high anti-interference, high real-time performance, etc.

[0072] The main function of the 1553B communication module is to realize the sending and receiving of data, and to parse and process the data. In the embodiment of the present application, the 1553B communication module is used to perform reliable data communication between the controller and the monitor. When the monitor needs to send the monitoring data to the controller via the 1553B bus, the 1553B communication module receives and decodes the monitoring data from the 1553B bus into a readable format, and then sends it to the controller.

[0073] The embodiment of the present application includes software-level error handling and recovery in the 1553B communication module to cope with complex working environments and unexpected events. In the 1553B communication module, error detection and verification are performed during data transmission to ensure the integrity and accuracy of the data. If an error is found during data transmission, the 1553B communication module will immediately send an error message to the controller or monitor and correct the transmission process.

[0074] The monitor acquires monitoring data of the generator, including:

[0075] The sensor obtains the monitoring data of the generator and uses the sensor as the monitor. At this time, the monitoring data is also called sensor data. The monitoring data can be parameters such as temperature and pressure of the monitoring equipment, as well as the operating status of the equipment. The operating status of the equipment can be the position, posture, speed, acceleration, force and other collected data of the Stirling power generation equipment.

[0076] After the monitor acquires the monitoring data of the generator and before the monitoring data is sent to the controller via 1553B communication, the monitoring data is subjected to denoising, filtering and normalization.

[0077] In the embodiment of the present application, the Stirling power generation equipment is a Stirling generator. The software part of the Stirling generator mainly includes algorithm processing of monitoring data, including denoising, filtering, normalization, etc., so that the data calculated by the system is more accurate and reliable.

[0078] Figure 6It is a block diagram of a monitoring data acquisition module. The monitoring data can be obtained through the monitoring data acquisition module. The monitoring data acquisition module mainly includes a power supply, an analog front-end circuit, a communication module and a main controller circuit. Among them, the power supply is a commonly used pulse width modulation PWM mode, that is, a control method in which the switching frequency is constant and the duty cycle is adjusted by changing the pulse width. According to the generator startup process, a power supply circuit is designed and configured in the circuit, and the main line of the power supply part is connected to the stator of the double-fed asynchronous generator, and the other is a branch line on the main line connected to the frequency converter. The main controller circuit mainly includes a 32-bit ARM architecture microprocessor chip and its external devices. The main controller circuit can collect the position, posture and speed data of the Stirling generator equipment output by the sensor data after electrode, amplification and filtering in real time, and calculate the actual value of the position, posture and speed of the Stirling generator equipment according to the solution formula in the analog-to-digital converter. By real-time detection of the actual value of the position, posture and speed of the Stirling generator equipment, the Stirling generator is controlled to operate efficiently and stably. The communication module mainly includes 1553B. The host computer can read the actual values ​​of the position, posture and speed of the Stirling generator sent by the monitoring data acquisition module in real time, and make a prediction of the operation process of the generator. The analog front-end circuit performs electrode, amplification and filtering on the detected sensor data signal; the main controller circuit reads the actual values ​​of the position, posture and speed of the Stirling generator converted by the analog-to-digital converter in real time; the communication module transmits the actual values ​​of the position, posture and speed of the Stirling generator encapsulated into frames by the main controller circuit at high speed and in real time. These three circuit modules form a three-level pipeline structure, which enables data acquisition, data caching and data transmission operations to be executed in parallel, realizing the synchronous acquisition and high-speed, real-time transmission of multiple detection data.

[0079] S300, the controller receives the monitoring data, generates a control instruction for the generator according to the monitoring data, and sends the control instruction to the monitor and the actuator via the 1553B communication.

[0080] When the controller needs to send control instructions or control signals containing control instructions to the monitor and actuator through the 1553B bus, the 1553B communication module encodes the control instructions or control signals containing control instructions into the 1553B bus format and sends them to the 1553B bus for transmission to the monitor and actuator.

[0081] In a possible implementation manner, the controller receives the monitoring data and generates a control instruction for the generator according to the monitoring data, including:

[0082] The controller receives the monitoring data, and determines the abnormality of the equipment state of the generator according to the monitoring data; and generates a control instruction for the generator according to the abnormality of the equipment state.

[0083] In an embodiment of the present application, when the controller determines that the operating status of the equipment is abnormal based on the operating status of the equipment contained in the monitoring data, the control system corresponding to the controller can select appropriate hardware devices such as shock-absorbing pads and / or buffers to protect the generator according to different equipment status abnormalities. At this time, the control instructions include operating instructions to control hardware devices such as shock-absorbing pads and / or buffers.

[0084] In a possible implementation manner, the controller receives the monitoring data and generates a control instruction for the generator according to the monitoring data, including:

[0085] The controller receives the monitoring data, and generates a control instruction for the generator according to the monitoring data and a preset timing and temperature start.

[0086] In the embodiment of the present application, the preset timing and temperature start means starting when a specific time and a specific temperature range are met. Specifically, the Stirling power generation system can start power generation through timing control; set a specific time, and the system automatically starts power generation at this specific time. The Stirling power generation system can also start power generation through constant temperature control; set a specific temperature range, and when the temperature reaches the specific temperature range, the system automatically starts power generation.

[0087] In the Stirling power generation system, both the timing and constant temperature start are implemented through the controller. The controller determines whether the temperature signal reaches a specific temperature range based on the temperature signal included in the monitoring data and the preset timing and constant temperature start. If so, and within the specific time, the controller controls the actuator to start the power generation system. The same method can also be used to control the actuator to stop the generator system. At this time, the control instruction includes an instruction to control the actuator to start the generator or an instruction to control the actuator to stop the generator.

[0088] In a possible implementation manner, the controller receives the monitoring data and generates a control instruction for the generator according to the monitoring data, including:

[0089] The controller receives the monitoring data, and generates a decision strategy for the generator based on the monitoring data and a mathematical model of motion state changes of a Stirling power generation device; and generates a control instruction for the generator based on the decision strategy.

[0090] In an embodiment of the present application, in order to prevent collision with the bar, it is necessary to establish a mathematical model of the motion state change of the Stirling power generation equipment. By analyzing and predicting the mathematical model of the motion state change of the Stirling power generation equipment, a decision strategy corresponding to the monitoring data can be generated, so that the movement and posture of the equipment can be controlled according to the control instructions generated by the decision strategy.

[0091] The mathematical model of the motion state change of Stirling generator equipment is also called the mathematical simulation model of the motion and state change of Stirling generator equipment and the nonlinear model of the motion state of Stirling generator. The family of nonlinear magnetization curves is the basis for analyzing various performances of Stirling generators. Only after obtaining the function of inductance with respect to current and position angle can the mathematical model of the motion state change of Stirling generator equipment be accurately established. Therefore, before establishing the mathematical model of the motion state change of Stirling generator equipment, the finite element (FEM) field calculation of Stirling generator is simulated by ANSYS software to obtain the inductance function and magnetic flux function, and then the nonlinear interpolation module in MATLAB / SIMULINK is used to establish the mathematical model of the motion state change of Stirling generator equipment. Based on MATLAB / SIMULINK, the inductance curve L of Stirling generator is used for modeling. Considering that the axial length of the motor is much larger than the air gap length, and the stator and rotor cores are both high-permeability electrical steel lamination structures, the axial end effect can be ignored, and the influence of eddy current is not taken into account, so it can be regarded as a two-dimensional static magnetic field problem. Then, the two-dimensional finite element software ANSYS can be used to perform numerical calculations on the two-dimensional static magnetic field of the generator, and the solutions under different currents i and different rotor positions θ can be obtained, thereby obtaining the magnetic field distribution of the generator and the magnetization curve family of the SR generator. After the ANSYS field calculation, it is a two-dimensional array of phase current i and position angle θ. The inductance curve family of the switched reluctance motor is obtained through two-dimensional finite element ANSYS software simulation calculation, and then the mathematical model of the motion state change of the Stirling generator equipment is obtained.

[0093] When the control instruction is an operation instruction for controlling hardware devices such as shock absorbing pads and / or buffers, the shock absorber and / or buffer receives the control instruction and protects the generator according to the control instruction. At this time, the shock absorber and the buffer are used as the monitor.

[0094] S500: The actuator receives the control instruction and operates the generator according to the control instruction.

[0095] The actuator controls the start and stop of the generator according to the control instructions, including instructions for controlling the actuator to start the generator or instructions for controlling the actuator to stop the generator; during the control process of the actuator, the movement and posture of the actuator are adjusted according to the control instructions generated by the decision strategy determined by the monitoring data collected by the sensor in real time.

[0096] In the embodiment of the present application, the control actuator is a software part that controls the movement and posture of the hardware actuator. In the Stirling power generation equipment, by adjusting the movement and posture of the actuator, the equipment can be prevented from collision and damage, thereby ensuring the safe operation of the equipment.
