A method for constructing a quantum echo state network model for an aero-engine fault early-warning. The method comprises: first, quantizing time series data of an aero-engine; then, using quantum state data as an input of a quantum network of a first layer and subjecting same to the action of a quantum recursive circuit, and then obtaining a probabilistic output by means of quantum measurement and transferring same to a reservoir of an echo state network of a second layer, so as to obtain a high-dimensional intermediate state; and finally, performing computation only once by using a least squares method, such that a weight matrix of an output layer can be obtained, thus completing network training. A trained quantum echo state network model is applied to aero-engine fault prediction, thereby providing relatively high-accuracy operation state prediction data of an engine at a future moment. In the present invention, a quantum controlled NOT gate is utilized to realize an entangled state, so as to approximately represent a possible coupling relationship between original input data, and a quantum rotation gate is set to be an adjustable parameter of a quantum network of a first layer, such that the distribution of data can be adjusted; moreover, an echo state network layer can exert the computational advantage of fast computation and completion of a final model with one-step training.

Disclosed in the present invention is an inhaul cable tension identification algorithm considering semi-rigid constraints at two ends. The present invention only requires basic parameters such as the length of an inhaul cable and mass per unit length of the inhaul cable, and uses modal identification algorithms, such as a random subspace algorithm and a frequency domain decomposition algorithm, to process signals collected by an acceleration sensor, so as to obtain corresponding first-order natural frequency and vibration mode, thus solving the cable tension without requiring any other data in advance. Compared with the existing string vibration theory, the present invention simplifies an inhaul cable into an equivalent single-degree-of-freedom system, corrects the first-order natural frequency of the inhaul cable using the vibration mode obtained by means of modal identification, thus avoiding cable tension identification errors caused by changes in the mechanical characteristics of inhaul cable boundaries, and improving the cable tension measurement efficiency and accuracy. The present invention has very good application prospects in the aspect of cable tension real-time monitoring of inhaul cable structures. This method is especially suitable for structures having the mechanical characteristics of inhaul cable boundaries continuously changing along with working conditions in actual operation, and has high practicability and wide applicability.

Disclosed are an omnidirectional observation under-actuated capsule robot and an axial flip magnetic control operation method therefor. A radially magnetized neodymium-iron-boron magnetic ring is placed within a cavity of a capsule sphere in a non-connection mode. The neodymium-iron-boron magnetic ring independently follows a rotating magnetic field, races around a capsule axis, and is completely suspended within the cavity of the capsule sphere filled with silicone oil. Under the actuation of a coaxial following magnetic moment, the under-actuated capsule sphere cannot self-rotate around the capsule axis, but the capsule axis can flip over synchronously following a rotation axis of the magnetic field. By means of the sequential scan within a conical range where the capsule axis forms a certain angle with a vertical direction using a universal magnetic field, or by means of continuous circular flips within a vertical plane parallel to an intestinal bending direction, the capsule robot can achieve omnidirectional observation and diagnosis within the body cavity and navigate along bending directions in constrained environments including the gastrointestinal tract. The present invention improves the scanning range of the capsule, enhances environmental adaptability, achieves high precision in capsule positioning and posture adjustment, enables stable rolling and navigation, and provides a good visual observation effect, thus holding good application prospects.

The present invention belongs to the field of aero-engine fault diagnosis. Provided is a fault-tolerant soft-hard hybrid control method for fault diagnosis of a sensor of an aero-engine. In the method, detection of a soft/hard fault of a sensor of an aero-engine and estimation of the true state of a system are realized by means of a Kalman filter group in a soft/hard fault diagnosis system. A designed soft-fault diagnosis system performs residual processing on measured values of sensors and estimated values of a group of Kalman filters, and solves the weighted sum of squares of same, so as to compare the weighted sum with a known threshold value to further detect whether there is a fault. A designed hard-fault diagnosis system compares the residual absolute value of the measured values of the sensors and the estimated value of a Kalman filter with the known threshold value, so as to further detect whether there is a fault. It is verified that by means of the method, the negative effect of a fault of a sensor of an aero-engine on the overall performance of a system can be effectively removed, such that the system is more stable, and various performance indexes can better meet requirements.

Disclosed in the present invention is an anhydrous anaerobic operation method, belonging to the technical field of chemistry. The present invention uses a low-melting-point organic solid instead of a liquid solvent subjected to anhydrous anaerobic treatment, and uses a vacuumizing method to remove air, so as to eliminate water and oxygen in a reaction system. After heating, the low-melting-point organic solid is melted to serve as a solvent, and reactants react under the heating condition. In addition, since the reaction system is all solid before heating, avoiding liquids being gasified and escaped due to excessively high degrees of vacuum, a higher degree of vacuum may be used for vacuumizing so as to thoroughly extract air including air adsorbed on the surface of the solid, thereby completely eliminating the water or oxygen in the reaction system, and avoiding the need of feeding an inert gas to replace air anymore. The method has simple operation and low costs and may be popularized and applied in a large scale.

The present application discloses an FxLMS structure-based active noise reduction system, a method, and a device. The device comprises: a primary path adaptive filter, a secondary path adaptive filter, and a subband filter set, the subband filter set being used to adjust a filter coefficient of the secondary path adaptive filter on the basis of a target playback sound. On the basis of an existing FxLMS structure, a subband filter set is added to the system, so that, in a process during which an active noise reduction device plays a target sound (such as a music signal), the subband filter set is used to whiten the target playback sound to eliminate correlation (this is due to the fact that the correlation in a music signal is strong, an eigenvalue is close to zero, a step size needs to be set smaller, and therefore a convergence speed of the adaptive filter is severely affected), so as to obtain a real-time filter coefficient of the secondary path adaptive filter. Compared with an offline method for modeling a secondary path using white noise, real-time online modeling is performed directly using target playback sound, improving user comfort. The method is more practical, and can be dynamically and automatically adjusted in real time.

Disclosed in the present invention is an image encryption method based on multi-scale compressed sensing and a Markov model. According to the difference between information carried in a low-frequency coefficient and a high-frequency coefficient of an image, different sampling rates are set for the low-frequency coefficient and the high-frequency coefficient of the image, such that the reconstruction quality of a decrypted image can be effectively improved. In addition, by means of combining a chaotic system with the Markov model, an encryption process is completed by using the policy of performing coefficient matrix intra-scrambling on the image first, then performing coefficient matrix inter-scrambling on the image, and finally performing independent diffusion and global diffusion. In the solution, compared with the existing solutions, an information entropy of a generated ciphertext image is higher, such that it is difficult to obtain related information of an original image, and the ciphertext image also has better plaintext sensitivity and key sensitivity, and thus can resist various attacks. Compared with a decrypted image generated in the existing solutions, a decrypted image obtained in the present invention has higher quality, and thus can obtain a better visual effect and more complete original image information.

A steam source system based on a steam-liquid ejector pressurization and flashing technology, relating to the technical field of waste heat utilization and steam generation. The system comprises a steam-liquid ejector, a flash tank, and a heater. Low-pressure water sucked from the flash tank is heated and pressurized by the steam-liquid ejector by using high-pressure steam, is heated by the heater, and then enters the flash tank to be flashed to low-pressure saturated steam; and unflashed saturated water is collected at the bottom of the flash tank, and is communicated with an ejection inlet of the steam-liquid ejector through a lead-out pipe at the bottom, thereby implementing cyclic pressurization and flashing. Meanwhile, a water replenishing pump transfers the low-temperature water to the flash tank to ensure continuous and stable operation of the steam source system; and a heating source of the heater is the tail flue gas of a steam boiler or other available medium- and low-temperature waste heat. The system generates multiple times of low-pressure flashed saturated steam with a small amount of high-pressure steam, realizes the recycling of waste heat such as tail flue gas of a boiler, improves the economy of process steam, and provides a flexible and adjustable steam source for heavy oil thermal recovery equipment, seawater desalination equipment, or sewage treatment equipment.
