[0002] Currently, in the industrial assembly field, tightening control systems are key equipment for achieving high-precision assembly. Traditional tightening control systems typically use one-way communication methods (such as ABZ incremental communication), which have the following problems:

[0003] First, its communication method is limited to one-way data transmission, failing to achieve real-time bidirectional interaction, resulting in slow system response and poor flexibility. Second, it lacks adaptability; tightening modules with different torque ranges require specific control box systems, making module interchangeability impossible, increasing equipment costs and maintenance difficulty. Furthermore, traditional operation methods suffer from low reliability; in case of communication interruptions or loose ports, there is a lack of effective fault detection and recovery mechanisms, impacting production efficiency. In addition, its level of intelligence is low: it cannot identify the torque output range in real time and lacks adaptive adjustment functions, making it difficult to meet the demands of high-precision assembly.

[0004] Therefore, in order to address the above-mentioned technical problems and deficiencies, there is an urgent need to design and develop an intelligent tightening control processing method, system, and platform based on dual communication channels. Summary of the Invention

[0068] S4. Based on the third data, and in combination with the first data and the second data, arbitrarily adapt and process tightening modules and control box systems with different torque ranges.

[0069] The creation of at least one bidirectional communication link based on RS485 and CAN bus also includes:

[0070] S11. Generate and acquire first signal data corresponding to the intelligent tightening control processing to be performed, and generate corresponding fourth data based on the first signal data; wherein, the first signal data is power-on prompt signal data; and the fourth data is handshake request data.

[0071] S12. Based on the fourth data, execute the handshake protocol corresponding to the verification process at least three times; wherein, if the verification is successful, a bidirectional data interaction channel is established and the communication rate is not less than 2Mbps; otherwise, re-verify the process.

[0072] The creation of at least one bidirectional communication link based on RS485 and CAN bus also includes:

[0073] S13. Based on the bidirectional communication link, monitor the status of the RS485 and CAN bus communication ports in real time; including fault detection and recovery processing.

[0074] S14. When an abnormal connection is detected at port A or port B, a corresponding fault code is generated and an audio alarm is triggered. After the port connection is restored, the handshake protocol verification and data integrity verification are automatically performed to restore the corresponding communication link.

[0075] The method of automatically performing handshake protocol verification and data integrity verification after the port connection is restored, and restoring the corresponding communication link, also includes:

[0076] S141. Perform CRC check processing on the transmitted data packets. If the check fails, resend the data packets until the check succeeds. After the check succeeds, resume real-time data interaction.

[0077] The process of generating and acquiring second data corresponding to the intelligent tightening control process, and generating corresponding third data in real time based on the second data, further includes:

[0078] S31. Based on the first data collected in real time, dynamically adjust and process the corresponding third data during the tightening process;

[0079] S32. Based on the first data, adjust and process the LED brightness, tilt angle, and forward / reverse control signal data in real time.

[0080] The process of generating and acquiring second data corresponding to the intelligent tightening control process, and generating corresponding third data in real time based on the second data, further includes:

[0081] S33. Based on the second data and combined with a preset current-torque conversion algorithm, calculate and generate corresponding fifth data; wherein, the fifth data is the current torque output value data;

[0082] S34. Based on the fifth data, automatically adjust the control parameter data in the processing control box system.

[0083] Specifically, in this embodiment of the invention, an intelligent tightening control method based on dual communication channels is provided, comprising the following steps: establishing a bidirectional communication link between the torque control module and the control box system via RS485 and CAN bus; collecting position sensor data and equipment status parameters in real time and transmitting them via RS485 and CAN bus respectively; monitoring the current parameters of the transmission part in real time based on the current detection unit and dynamically identifying the current torque output range; and automatically matching the control parameters of the control box system according to the identification result to achieve arbitrary adaptation of modules with different torque ranges.

[0084] The RS485 communication channel is used to transmit position sensor data and torque control parameters, while the CAN bus communication channel is used to transmit equipment status parameters, including LED brightness, tilt angle, forward / reverse signals, and transmission start signals. The step of dynamically identifying the torque output range includes: real-time acquisition of current data from the transmission motor and reducer via a current detection unit; calculation of the current torque output value based on a preset current-to-torque conversion algorithm; and automatic adjustment of the control parameters of the control box system according to the torque output value.

[0085] The steps for establishing the bidirectional communication link include: after the system is powered on, the torque control module sends a handshake request to the control box system via RS485 and CAN bus; the control box system responds to the handshake request and performs a three-way handshake protocol verification; after successful verification, a bidirectional data interaction channel is established with a communication rate of not less than 2Mbps.

[0086] The method further includes fault detection and recovery steps: real-time monitoring of the status of RS485 and CAN bus communication ports; when an abnormal connection is detected at port A or port B, a specific fault code is generated and a voice alarm is triggered; after the port connection is restored, handshake protocol verification and data integrity verification are automatically performed to restore the communication link. The data integrity verification step includes: performing CRC verification on the transmitted data packets; if the verification fails, retransmitting the data packets until the verification succeeds; and restoring real-time data interaction after successful verification.

[0087] The method further includes an adaptive adjustment step: dynamically adjusting the torque output during the tightening process based on real-time acquired position sensor data; and adjusting LED brightness, tilt angle, and forward / reverse control signals in real time based on equipment status parameters. The method also includes a modular adaptation step: achieving mechanical connection between torque control modules of different sizes and torque ranges and the control box system through standardized interfaces; and adapting transmission components with different power requirements through a universal power interface (5-48V wide voltage input). A heat dissipation control step is also included: real-time monitoring of the temperature parameters of the torque control module; and dynamic adjustment of the cooling fan speed based on the temperature data to ensure the module operates within a safe temperature range. Finally, a data visualization step is provided: transmitting real-time acquired position sensor data, torque output values, and equipment status parameters to an interface display system; and displaying system status, fault information, and operation prompts in real time through a graphical interface, supporting human-machine interaction.

[0088] In other words, the new intelligent industrial control and communication tightening system, as an innovative combination structure (RS485 and CAN bus communication), has the advantage of being able to freely match the handle plate and transmission part with the control box system compared to the existing communication technologies on the market. It does not require distinguishing the torque range to adapt to a specific control box system, thus promoting efficient operation and convenient production.

[0089] like Figure 2 , Figure 3 As shown, the differences between the new intelligent communication control system and the general-purpose communication control framework are as follows: **Differences in Communication Methods:** The communication methods between the torque control module and the control box and display system are different. The new intelligent communication system adopts a bidirectional combined architecture of RS485 and CAN bus communication, facilitating random adaptation to any control box and display system interface; the general-purpose communication system mainly uses ABZ incremental unidirectional communication, communicating only with a single control box and display system. **Differences in Reading Position Signals:** The new intelligent torque control module has an additional handle control module, enabling real-time reading of position sensor data; the general-purpose torque control module can only read sensor position signals in real-time through the control box and display system. **Differences in Control Boxes and Display Systems Corresponding to Different Torque Ranges:** Different torque output torques of the torque control module require different control boxes and display systems. The new intelligent communication control system allows the torque control module to be connected to any interchangeable control box and display interface system, regardless of whether the torque output is large or small. In contrast, the universal communication system requires a single torque control module to be connected to a single control box and display interface system for both large and small torque outputs.

[0090] like Figure 4As shown: The RS485 (MAX14783) chip and CAN (TJA1042) chip of the torque control module communicate with the RS485_A (MAX14783) and CAN_A (TJA1042) chips of the control box and display interface system via twisted-pair cables (within 20mm in length) to maintain a high communication rate of 2M for real-time data transmission. If port A or port B becomes loose or is directly pulled out, the control box and display interface system will display a corresponding fault code, accompanied by a voice message. If port A or port B is restored to a secure connection, the RS485 and CAN chips of the torque control module and the RS485_A and CAN_A chips of the control box and display interface system will continue to request and respond, ensuring correct and real-time data exchange and guaranteeing the normal operation of the entire intelligent control tightening system.

[0091] RS485 and CAN communicate using different data. RS485 primarily performs... Figure 1 Real-time transmission of sensor data ensures the accuracy and reliability of position signals, resulting in precise and stable output torque during tightening. The CAN bus is used for data transmission of auxiliary functions, mainly covering real-time data transmission of LED brightness adjustment, real-time tilt angle response of the torque control module, forward and reverse switch signals, and transmission part start switch signals.

[0092] The torque control module covers a different range of torque and has varying dimensions. Each intelligent industrial control tightening system has a different torque capacity, primarily reflected in the output torque of the transmission components (motor and reducer) and their size. Low-torque tightening control systems have smaller transmission components and a thinner overall appearance; high-torque systems have thicker transmission components and a larger overall appearance. This new intelligent industrial control communication tightening system can automatically identify the torque output based on RS485 and CAN communication. It primarily identifies the torque capacity by measuring the current consumed by the motor and reducer in the transmission components.

[0093] The innovation of this invention lies in its dual-communication channel architecture: an RS485 communication channel for transmitting high-precision position sensor data and torque control parameters, ensuring the accuracy and stability of the tightening process; and a CAN bus communication channel for transmitting equipment status parameters (such as LED brightness, tilt angle, forward / reverse signals, etc.) to achieve real-time control of auxiliary functions. The dual-channel communication rate can reach 2Mbps, supporting high-speed data interaction.

[0094] Adaptive recognition technology: The current parameters of the transmission components (motor and reducer) are monitored in real time through a current detection unit. Based on a current-to-torque conversion algorithm, the current torque output range is dynamically identified. The control parameters of the control box system are automatically matched to achieve arbitrary adaptation to modules with different torque ranges.

[0095] Fault detection and recovery mechanism: When an abnormal connection is detected on a communication port (port A or port B), the system generates a specific fault code and triggers an audio alarm. After the port connection is restored, the system automatically performs handshake protocol verification and data integrity check to ensure reliable reconstruction of the communication link.

[0096] Modular design: The torque control module adopts a standardized interface design, supporting mechanical connections between modules of different sizes and torque ranges and the control box system. A universal power interface (20-48V wide voltage input) and a modular heat dissipation structure adapt to diverse application scenarios.

[0097] In other words, the present invention provides a novel intelligent industrial control and communication tightening system. This system employs a torque control module, a control box, and an interface display system that interact through two different communication methods: RS485 and CAN bus communication. The interaction rate can reach over 2Mbps. Furthermore, the torque control module is not limited by torque magnitude or size and can be interchanged with either the control box or the interface display system, while ensuring the stability and reliability of the entire communication system. The key point is that each of the two different communication methods (RS485 and CAN) has its own functional effect to automatically identify the torque magnitude. Different torque ranges and external dimensions can be arbitrarily adapted to any control box and display interface system. By using two different communication interaction methods (RS485 and CAN), the system's communication performance and reliability are improved. Simultaneously, it achieves intelligent tightening control, reduces the impact of electromagnetic interference, and improves production efficiency.

[0098] To achieve the above objectives, the present invention also provides an intelligent tightening control processing system based on dual communication channels, such as... Figure 5 As shown, the system specifically includes:
