Description
Technical Field
[0001] This invention relates to an intelligent constant torque loading laser ranging and tracking system. Background Technology
[0002] Foreign countries have mature technologies in constant torque loading, laser ranging, and dynamic tracking. German, Japanese, and American companies have formed technological barriers in high-precision torque control, non-contact ranging, real-time tracking, and multi-parameter coordination. Their systems are highly stable and accurate, and are widely used in fields such as testing, assembly, transmission, and aerospace.
[0003] Domestic systems in this field are mostly single-function integrations, generally suffering from problems such as large torque control fluctuations, slow tracking response, low ranging accuracy, poor coordination, and insufficient intelligence. High-end testing and tracking equipment relies on imports, resulting in high costs and weak adaptability. With the increasing demands for intelligent manufacturing and quality inspection, the demand for intelligent systems integrating constant torque loading, laser ranging, and real-time tracking is growing rapidly, indicating a huge potential for domestic substitution. Summary of the Invention
[0004] The purpose of this invention is to overcome the pain points of existing technologies, such as unstable torque loading, large ranging error, tracking delay, and independent modules that cannot be coordinated for control. It provides an intelligent constant torque loading laser ranging and tracking system that integrates constant torque closed-loop stable loading, high-precision laser ranging, servo dynamic real-time tracking, and multi-parameter intelligent coordinated control, thereby improving the accuracy and automation level of precision detection, performance testing, and dynamic alignment.
[0005] The objective of this invention is achieved as follows: The intelligent constant torque loading laser ranging and tracking system consists of nine core modules: main control core module, constant torque loading module, laser ranging module, servo dynamic tracking module, signal acquisition and conditioning module, environmental error compensation module, multi-parameter collaborative control module, human-machine interaction and data management module, and fault alarm and safety protection module. The main control core module is the central hub of the system, and it has bidirectional communication connections with the constant torque loading module, laser ranging module, servo dynamic tracking module, signal acquisition and conditioning module, and multi-parameter collaborative control module; at the same time, it has unidirectional connections with the human-machine interaction and data management module and the fault alarm and safety protection module. The constant torque loading module has a built-in torque sensor. The sensor output is connected to the signal acquisition and conditioning module. After signal filtering, amplification, and AD conversion, the signal is uploaded to the main control core module. The main control core module sends control commands to the constant torque loading module to form a torque closed-loop control circuit.
[0006] The laser ranging module is electrically connected to the environmental error compensation module and the main control core module respectively; the laser ranging module collects target distance data in real time and sends it to the environmental error compensation module for real-time correction of temperature, vibration and deflection errors, and the accurate distance data after compensation is fed back to the main control core module; The servo dynamic tracking module includes a servo driver, a servo motion mechanism, and a positioning execution unit; it receives tracking path instructions and position deviation signals from the main control core module, and links with laser ranging and positioning information to achieve real-time target following and precise positioning, while transmitting real-time position and motion status back to the main control core module. The multi-parameter collaborative control module receives three types of parameters from the main control core module: real-time torque value, laser ranging value, and tracking position coordinate. It performs multi-source data fusion calculation and adaptively adjusts torque output, ranging calibration parameters, servo tracking speed and path to achieve coordinated linkage of the three parameters. The human-computer interaction and data management module communicates with the main control core module to realize parameter setting, real-time data display, historical data storage, curve playback, and test report export; the fault alarm and safety protection module monitors the operating status of each module in real time, triggers alarms when there are over-limit, overload, or abnormal displacement, and sends shutdown protection commands to the main control core module.

It develops an integrated system with stable constant torque loading, high-precision laser ranging, real-time target tracking, and intelligent closed-loop control, meeting the needs of precision testing, performance testing, and dynamic alignment scenarios. Furthermore, it offers the following advantages: Integrated Structure: The three-in-one modular design is compact and highly adaptable to installation, replacing multiple separate devices; High-precision control: torque closed-loop stabilization control, laser error compensation, and servo fast tracking significantly improve testing and alignment accuracy; High adaptability to working conditions: adaptive disturbance suppression and error compensation, suitable for complex industrial sites such as vibration and temperature changes; High level of intelligence: multi-parameter collaboration, automatic data traceability, unattended operation, reducing labor costs; Breaking the dependence on imports, it can be widely used in precision manufacturing, automotive parts, motor bearings, and automated testing lines, with significant economic and industrial value.

[0012] like Figures 1 to 4 This invention relates to an intelligent constant torque loading laser ranging and tracking system, which consists of nine core modules: a main control core module, a constant torque loading module, a laser ranging module, a servo dynamic tracking module, a signal acquisition and conditioning module, an environmental error compensation module, a multi-parameter collaborative control module, a human-machine interaction and data management module, and a fault alarm and safety protection module.
[0013] The main control core module is the central hub of the system, and it has bidirectional communication connections with the constant torque loading module, laser ranging module, servo dynamic tracking module, signal acquisition and conditioning module, and multi-parameter collaborative control module; at the same time, it has unidirectional connections with the human-machine interaction and data management module and the fault alarm and safety protection module.
[0014] The constant torque loading module has a built-in torque sensor. The sensor output is connected to the signal acquisition and conditioning module. After signal filtering, amplification, and AD conversion, the signal is uploaded to the main control core module. The main control core module sends control commands to the constant torque loading module to form a torque closed-loop control circuit.
[0015] The laser ranging module is electrically connected to the environmental error compensation module and the main control core module respectively. The laser ranging module collects target distance data in real time and sends it to the environmental error compensation module for real-time correction of temperature, vibration and angular errors. The accurate distance data after compensation is fed back to the main control core module.
[0016] The servo dynamic tracking module includes a servo driver, a servo motion mechanism, and a positioning execution unit. It receives tracking path instructions and position deviation signals from the main control core module, and links with laser ranging and positioning information to achieve real-time target following and precise positioning. At the same time, it transmits the real-time position and motion status back to the main control core module.
[0017] The multi-parameter collaborative control module receives three types of parameters from the main control core module: real-time torque value, laser ranging value, and tracking position coordinates. It performs multi-source data fusion calculations and adaptively adjusts the torque output, ranging calibration parameters, servo tracking speed, and path to achieve coordinated linkage of the three parameters.
[0018] The human-computer interaction and data management module communicates with the main control core module to realize parameter setting, real-time data display, historical data storage, curve playback, and test report export; the fault alarm and safety protection module monitors the operating status of each module in real time, triggers alarms when there are over-limit, overload, or abnormal displacement, and sends shutdown protection commands to the main control core module.
[0019] The module as a whole adopts a hierarchical centralized control architecture: Bottom layer: Execution perception layer (constant torque loading mechanism, torque sensor, laser ranging probe, servo tracking execution mechanism); Middle layer: Signal processing and control layer (signal acquisition and conditioning, environmental error compensation, constant torque closed-loop control, dynamic tracking drive, multi-parameter collaborative controller); Top layer: Scheduling and human-machine management layer (main control core, human-machine interaction, data storage, fault safety protection); each module adopts bus + point-to-point bidirectional signal interconnection to realize full-process control of command issuance, data feedback, closed-loop adjustment, and collaborative linkage.
[0020] The three-in-one integrated architecture integrates constant torque loading, laser ranging, and dynamic servo tracking into one, replacing the traditional multi-device separate operation mode. Constant torque closed-loop control: Real-time torque sampling, dynamic adaptive adjustment of output, suppression of disturbances under varying operating conditions, ensuring stable torque without impact, torque control range: 0–50 N·m continuously adjustable, control accuracy ±0.1%FS; Real-time compensation for environmental errors in laser ranging: Establish a correction model for errors in temperature, vibration, and installation angle to compensate for ranging deviations in real time. Laser ranging range: 0–500mm, ranging accuracy ±0.01mm; Dynamic target intelligent tracking: Laser positioning guides servo drive, intelligently plans tracking path, and achieves low latency and no overshoot repetitive positioning. Tracking response time ≤20ms, and repetitive positioning accuracy ≤±0.005mm.
