[0002] In the fields of industrial automation, automobile manufacturing, aerospace, etc., it is crucial to accurately and real-timely monitor the torque of rotating mechanical components. Most traditional torque sensors have the following deficiencies:

[0003] Most torque sensors adopt contact measurement methods, that is, the sensor directly contacts the rotating shaft. Long-term use will cause wear of the sensor, affecting the measurement accuracy and the service life of the sensor; existing torque sensors often fail to meet the requirements of high-precision measurement. Especially in the case of large dynamic torque changes, the stability of the sensor is poor and it is easily interfered by external factors; traditional torque sensors have a slow response speed and cannot meet the demand for rapid response to torque changes in high-speed rotating systems; many torque sensors require a complex installation process, increasing the installation cost and the maintenance difficulty; the data transmission method of traditional torque sensors is single and mostly relies on wired connections, restricting their application in certain occasions. Especially for devices that need to be frequently moved or are far from the data processing center, it is not flexible enough.

[0004] Therefore, we provide a high-precision dynamic torque real-time monitoring sensor to solve the above problems. Content of the Utility Model

[0024] Please refer to Figures 1-3 , the present invention is a high-precision dynamic torque real-time monitoring sensor, including a sensor body 1 and a rotor detection end 2 that is used in non-contact cooperation with the sensor body 1. The sensor body 1 includes a base 11, a sensor main body 12 fixed on the upper side of the base 11, a magnetic induction coil end 17 provided at one end of the sensor main body 12, an end cover 13 provided at the other end of the sensor main body 12, a signal processing module 14 provided on the upper part of the sensor main body 12, a communication interface 16 embedded on the side of the signal processing module 14, and a power supply module 15 fixed on the upper side of the signal processing module 14; the rotor detection end 2 includes an induction shaft 21 that cooperates with the magnetic induction coil end 17 and a rotor shaft 22 that rotates synchronously with the induction shaft 21.

[0025] Regarding the further description of the above structure: The signal processing module 14 is internally provided with an amplifier, a filter, and a microprocessor, and the signal processing module 14 is connected to the built-in power supply unit of the power supply module 15. A wireless communication unit is also provided inside the signal processing module 14. The wireless communication unit and the communication interface 16 form a communication system. A magnetic induction coil is wound inside the magnetic induction coil end 17, and the magnetic induction coil end 17 induces the induction shaft 21 made of a magnetic material. The rotor shaft 22 cooperates with an external rotation drive, and the rotor shaft 22 is threadedly fitted and installed at the end of the induction shaft 21.

[0026] A notch is provided at the middle position of the lower side of the base 11, and the edge of the base 11 is fixed to the external contact surface through fasteners.

[0027] This monitoring sensor uses a non-contact torque monitoring method, which avoids the wear problems of traditional contact torque sensors, improves the service life and reliability of the sensor. The magnetic induction coil end 17 induces with the induction shaft 21 made of magnetic material, achieving high-sensitivity detection of the torque change of the rotating shaft, enabling the sensor to accurately capture minute torque changes and improving the measurement accuracy.

[0028] The signal processing module 14 with an built-in amplifier, filter and microprocessor can effectively preprocess the collected signals and perform data analysis, reducing the influence of external interference and enhancing the reliability and accuracy of the data. The combined communication system of the wireless communication unit and the communication interface 16 not only supports wired communication but also enables wireless data transmission, facilitating connection with various types of monitoring systems and enhancing the flexibility and application scope of the system.

[0029] Further explanations about this monitoring sensor are as follows:

[0030] In the sensor body 1, the base 11 serves as the basic support structure of the entire sensor. There is a notch in the middle of the lower side of the base 11 for easy installation and disassembly. The edge of the base 11 is connected to an external fixed surface (such as the shell of a mechanical device) through fasteners (such as screws) to ensure the stable installation of the sensor. The sensor main body 12 is fixed on the upper side of the base 11 and is the core part of the sensor body 1, responsible for detecting and preliminarily processing torque signals. The magnetic induction coil end 17 is arranged at one end of the sensor main body 12 and internally wound with a magnetic induction coil for detecting the magnetic field change generated by the rotor detection end 2. The end cover 13 is arranged at the other end of the sensor main body 12 to protect the internal components. The signal processing module 14 is arranged on the upper part of the sensor main body 12 and internally equipped with circuit elements such as an amplifier, a filter and a microprocessor, for processing the signals captured by the magnetic induction coil end 17 and converting them into data available for analysis. The communication interface 16 is embedded on the side of the signal processing module 14 for wired communication with external devices. The power supply module 15 is fixed on the upper side of the signal processing module 14 and internally equipped with a power supply unit (such as a battery or an energy harvesting device) to supply power to the entire sensor. The wireless communication unit is integrated inside the signal processing module 14 and together with the communication interface 16 constitutes a communication system for wireless data transmission with external devices.

[0031] In the rotor detection end 2, the induction shaft 21 cooperates with the magnetic induction coil end 17. When the induction shaft 21 rotates with the external rotating shaft, a changing magnetic field will be generated at the magnetic induction coil end 17. The rotor shaft 22 rotates synchronously with the induction shaft 21 and is installed at the end of the induction shaft 21 through a threaded fit, cooperating with an external rotary drive (such as a motor) to transmit the rotary torque.

[0032] When the rotor shaft 22 rotates with an external rotating shaft, the induction shaft 21 will change its relative position with respect to the end 17 of the magnetic induction coil, thereby generating a changing magnetic field within the magnetic induction coil. The changing magnetic field is captured by the magnetic induction coil and converted into an electrical signal. The electrical signal is then processed by an amplifier and a filter in the signal processing module 14 to remove noise and enhance the signal strength. The processed signal is further analyzed and processed by a microprocessor to calculate the torque value, which is then sent to an external monitoring system through a wireless communication unit or a communication interface 16.
