[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the 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.

[0021] Example 1

[0022] like Figure 1-3As shown in the figure, it is the first embodiment of the present invention, which provides an intelligent real-time monitoring device for a hydraulic cylinder, including a hydraulic cylinder assembly 1 and an optimization system 3. The hydraulic cylinder assembly 1 includes a cylinder body 101, an end cover 102, a bottom cover 103, a piston rod 104 and a piston body 105. The end cover 102 and the bottom cover 103 are respectively fixed to the two ends of the cylinder body 101. The piston body 105 is installed in the inner cavity of the cylinder body 101 and is movably connected to the inner cavity of the cylinder body 101. One end of the piston rod 104 is fixedly connected to the piston body 105, and the other end of the piston rod 104 passes through the end cover 102 and extends to the outside of the cylinder body 101. The surface of the hydraulic cylinder assembly 1 A monitoring component 2 is installed, and the monitoring component 2 includes a pressure sensor 201, a position sensor 202 and an acceleration sensor 203. The pressure sensor 201 is used to monitor the oil inlet pressure, the position sensor 202 is used to monitor the motion trajectory of the piston body 105, and the acceleration sensor 203 is used to monitor the motion state of the hydraulic cylinder. The optimization system 3 includes a data acquisition module 301, a data processing module 302 and a control execution module 303. The data acquisition module 301 is used to analyze the data collected by the monitoring component 2, the data processing module 302 is used to analyze the data, and the control execution module 303 sends instructions. The optimization system 3 is integrated with the cloud computing platform.

[0023] like Figure 1-3 As shown, a hydraulic cylinder can be formed by combining a cylinder body 101, an end cover 102, a bottom cover 103, a piston rod 104 and a piston body 105. The oil inlet pressure of the hydraulic cylinder, the movement position of the piston body 105 and the movement state data of the hydraulic cylinder can be collected in real time by a pressure sensor 201, a position sensor 202 and an acceleration sensor 203, and the data are sent to a cloud computing platform through wireless communication. The cloud computing platform performs artificial intelligence calculations through an optimization system 3. A data acquisition module 301 receives the collected data and extracts useful data. The data processed by the data acquisition module 301 is analyzed by a data processing module 302.

[0024] Example 2

[0025] Reference Figure 1-3 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, the data processing module 302 includes a machine learning algorithm, a deep learning algorithm and a reinforcement learning algorithm. The monitoring component 2 and the optimization system 3 are connected via wireless communication. The wireless communication connection can use Wi-Fi, Bluetooth, LoRa or NB-IoT, and the data is transmitted to the cloud platform in real time.

[0027] Machine learning algorithms build predictive models by learning from historical data, predict future operating conditions, and make adjustments accordingly.

[0028] Deep learning algorithms use neural networks to analyze and model complex data, while reinforcement learning algorithms optimize control strategies and perform adaptive adjustments through continuous trial and error.

[0029] like Figure 1-3 As shown, the pressure sensor 201 can monitor the oil inlet pressure of the hydraulic cylinder in real time. Excessive or insufficient pressure will lead to reduced efficiency of the hydraulic system. By monitoring the oil inlet pressure in real time through the pressure sensor 201, the pressure abnormality can be discovered in time, so that corresponding measures can be taken. The position sensor 202 can adopt a magnetostrictive sensor, and use the magnetic field and the phenomenon called torsional strain to accurately measure the position of the piston body 105, so as to provide accurate position feedback and realize accurate control of the movement of the hydraulic cylinder. The acceleration sensor 203 can not only provide speed monitoring, but also monitor vibration. By monitoring the vibration, the excessive vibration of the hydraulic cylinder may be caused by unstable hydraulic oil pressure or internal wear of the hydraulic cylinder, so as to help identify and diagnose hydraulic system faults, and provide real-time acceleration data to help optimize the control strategy of the hydraulic system. By monitoring the acceleration of the hydraulic cylinder, the oil inlet pressure and flow of the hydraulic system can be adjusted, so as to improve the efficiency and response speed of the hydraulic system.

[0030] Example 3

[0031] Reference Figure 1-3 , which is the third embodiment of the present invention, and this embodiment is based on the previous two embodiments.

[0032] In this embodiment, the hydraulic cylinder assembly 1 also includes a first seal 106, an earring 107, a second seal 108, a third seal 109, an oil inlet pipe 110 and a reversing solenoid valve 111. There are two oil inlet pipes 110 and two reversing solenoid valves 111, and pressure sensors 201 are provided on the surfaces of the two oil inlet pipes 110.

[0033] The first seal 106 is located in the inner cavity of the cylinder 101 and fixedly connected to the piston body 105 . The second seal 108 is fixed to the front end of the inner cavity of the end cover 102 . The end of the piston rod 104 away from the piston body 105 passes through the second seal 108 .

[0034] The third sealing member 109 is fixed at the connection between the position sensor 202 and the bottom cover 103. The position sensor 202 is installed at one end of the bottom cover 103. The detection end of the position sensor 202 passes through the inner cavity of the cylinder body 101. The piston rod 104, the piston body 105 and the piston body 105 are all sleeved on the detection end of the position sensor 202.

[0035] The two oil inlet pipes 110 are respectively installed on the surface of the end cover 102 and the bottom cover 103. The top of the oil inlet pipe 110 is connected to the reversing solenoid valve 111. The end of the piston rod 104 located outside the cylinder body 101 is fixedly connected to the earring 107, and the acceleration sensor 203 is installed on the surface of the earring 107.

[0036] like Figure 1-3 As shown, when the rear reversing solenoid valve 111 feeds oil into the inner cavity of the cylinder 101 through the oil inlet pipe 110, the front reversing solenoid valve 111 discharges the hydraulic oil into the oil tank. The hydraulic oil entering through the rear reversing solenoid valve 111 pushes the first sealing member 106 and the piston body 105 to move toward the front end of the inner cavity of the cylinder 101, so that the piston body 105 can push the piston rod 104 to move outside the cylinder 101. When the oil is fed through the front reversing solenoid valve 111, the rear reversing solenoid valve 111 discharges the oil into the oil tank, so that the hydraulic oil The oil pushes the piston body 105 to move toward the rear end of the inner cavity of the cylinder body 101, thereby realizing the telescopic movement of the hydraulic cylinder. The first seal 106 can not only prevent the rear end hydraulic oil from entering the front end, but also prevent the front end hydraulic oil from entering the rear end, thereby effectively avoiding the reduction of hydraulic efficiency due to hydraulic oil leakage. The second seal 108 is used to seal the connection between the piston rod 104 and the end cover 102 to prevent oil leakage or dust from entering, causing hydraulic oil pollution and reduced hydraulic power.

[0037] When in use, when the rear-end reversing solenoid valve 111 feeds oil into the inner cavity of the cylinder body 101 through the oil inlet pipe 110, the front-end reversing solenoid valve 111 discharges the hydraulic oil into the oil tank, and the hydraulic oil entering through the rear-end reversing solenoid valve 111 pushes the first sealing member 106 and the piston body 105 to move toward the front end of the inner cavity of the cylinder body 101, so that the piston body 105 can push the piston rod 104 to move toward the outside of the cylinder body 101. When oil is fed through the front-end reversing solenoid valve 111, the rear-end reversing solenoid valve 111 discharges oil into the oil tank, so that the hydraulic oil pushes the piston body 105 to move toward the rear end of the inner cavity of the cylinder body 101, thereby realizing the telescopic movement of the hydraulic cylinder;

[0038] The pressure sensor 201, the position sensor 202 and the acceleration sensor 203 can collect the oil inlet pressure of the hydraulic cylinder, the movement position of the piston body 105 and the movement state data of the hydraulic cylinder in real time, and send them to the cloud computing platform through wireless communication. The cloud computing platform performs artificial intelligence calculations through the optimization system 3. The data acquisition module 301 receives the collected data and extracts useful data. The data processed by the data acquisition module 301 is analyzed by the data processing module 302. The data processing module 302 can predict when a failure may occur through machine learning algorithms, deep learning algorithms and reinforcement learning algorithms, and remind maintenance personnel to perform preventive maintenance to avoid sudden shutdown of the equipment. The data processing module 302 can also generate the optimal adjustment plan based on the analyzed data, and send corresponding adjustment instructions through the control execution module 303, so as to realize real-time monitoring of the hydraulic cylinder. The operation data is analyzed and processed by the artificial intelligence algorithm, which can not only timely discover the operation failure of the hydraulic cylinder and take corresponding maintenance measures, but also automatically adjust the working parameters of the hydraulic system according to the operation data, optimize the performance of the hydraulic cylinder through the artificial intelligence algorithm, realize efficient and accurate control, and at the same time reduce energy consumption, extend the life of the hydraulic cylinder, reduce the occurrence of failures, and thus ensure the stable operation of the equipment.
