Based on the fourth data, execute the handshake protocol for verification processing at least three times; wherein, after the verification is passed, a bidirectional data interaction channel is established and the communication rate is not less than 2 Mbps; otherwise, re-verification processing is performed.

Based on the bidirectional communication link, monitor the status of the RS485 and CAN bus communication ports in real time; wherein, it includes fault detection and recovery processing; S14. When it is detected that the connection of port A or port B is abnormal, generate corresponding fault codes and trigger voice alarms; after the port connection is restored, automatically execute the handshake protocol verification and data integrity check, and restore the corresponding communication link.

Perform CRC check processing on the transmitted data packets. When the check fails, retransmit the data packets until the check is successful; after the check is successful, resume real-time data interaction.

[0034] The generation and acquisition of second data corresponding to the intelligent tightening control process to be processed, and the generation of corresponding third data in real time according to the second data also includes: S31. Dynamically adjust and process the corresponding third data during the tightening process according to the first data collected in real time; S32. Based on the first data, adjust and process the LED brightness, tilt angle and forward and reverse control signal data in real time.

[0035] Generating and obtaining second data corresponding to the to-be-intelligently tightened control process, and generating corresponding third data in real time according to the second data, further includes: S33. Based on the second data and in combination with a preset current-torque conversion algorithm, calculating and generating corresponding fifth data; wherein, the fifth data is current torque output value data; S34. Automatically adjusting control parameter data in the control box system according to the fifth data.

[0036] Specifically, in an embodiment of the present invention, an intelligent tightening control method based on a dual communication channel is provided, including the following steps: establishing a two-way communication link between a torque control module and a control box system through RS485 and CAN buses; collecting position sensor data and device status parameters in real time and transmitting them through RS485 and CAN buses respectively; based on a current detection unit, monitoring current parameters of a transmission part in real time and dynamically identifying a current torque output range; automatically matching control parameters of the control box system according to an identification result to achieve arbitrary adaptation of different torque range modules.

[0037] The RS485 communication channel is used to transmit position sensor data and torque control parameters, and the CAN bus communication channel is used to transmit device status parameters, including LED brightness, tilt angle, forward and reverse signals, and transmission part start signals. The step of dynamically identifying the torque output range includes: collecting current data of a transmission part motor and a speed reducer in real time through a current detection unit; calculating a current torque output value based on a preset current-torque conversion algorithm; automatically adjusting control parameters of the control box system according to the torque output value.

[0038] The step of establishing the two-way communication link includes: after the system is powered on, the torque control module sends a handshake request to the control box system through RS485 and CAN buses; the control box system responds to the handshake request and executes a three-way handshake protocol verification; after the verification is passed, a two-way data interaction channel is established, and the communication rate is not lower than 2 Mbps.

[0039] The method further includes a fault detection and recovery step: monitoring the status of RS485 and CAN bus communication ports in real time; when it is detected that the connection of port A or port B is abnormal, generating a specific fault code and triggering a voice alarm; after the port connection is restored, automatically executing handshake protocol verification and data integrity verification to restore the communication link. Wherein, the data integrity verification step includes: performing CRC verification on transmitted data packets; when the verification fails, resending the data packets until the verification is successful; after the verification is successful, restoring real-time data interaction.

[0040] The method further includes an adaptive adjustment step: dynamically adjusting the torque output during the tightening process according to the position sensor data collected in real time; and based on the device status parameters, adjusting the LED brightness, tilt angle, and forward / reverse control signal in real time. The method also includes a modular adaptation step: achieving the mechanical connection between the torque control module with different appearance sizes and torque ranges and the control box system through a standardized interface; and adapting the transmission components with different power requirements through a universal power interface (5 - 48V wide voltage input). And a heat dissipation control step: monitoring the temperature parameters of the torque control module in real time; dynamically adjusting the rotation speed of the cooling fan according to the temperature data to ensure that the module operates within a safe temperature range. A data visualization step: transmitting the position sensor data, torque output value, and device status parameters collected in real time to the interface display system; and displaying the system status, fault information, and operation prompts in real time through a graphical interface to support human - machine interaction operations.

[0041] That is to say, currently, the new intelligent industrial control communication tightening system, as an innovative combined structure (RS485 and CAN bus communication), compared with the technical communication technologies on the market, has the advantage that the handle board and the transmission part can be randomly matched with the control box system without the need to distinguish torque segments to adapt to a specified unique control box system, advocating efficient operation and convenient production.

[0042] Such as Figure 2 , Figure 3 As shown, the comparison differences between the new intelligent communication control system and the general - type communication control framework diagram are as follows: differences in communication methods, the communication methods between the torque control module, the control box, and the interface display system are different. The new intelligent communication system adopts a two - way combined architecture of RS485 and CAN bus communication, which is convenient for randomly adapting to any control box and display system interface; the general - type communication system mainly adopts the ABZ incremental one - way communication method and only communicates with a single control box and display interface system. Differences in reading position signals, compared with the torque control module, the new intelligent torque control module has an additional handle control module inside, which can read the position data of the position sensor in real time; the general - type torque control module can only read the sensor position signal in real time through the control box and display interface system. Differences in the control box and display interface systems corresponding to different torque ranges, when the torque output of the torque control module is different, the control box and display interface system it adapts to is also different. For the new intelligent communication control system, the torque control module can be connected to any interchangeable control box and display interface system regardless of whether the output torque is large or small; for the general - type communication system, a torque control module with a large - torque output can only be connected to a single control box and display interface system, and a torque control module with a small - torque output can only be connected to a single control box and display interface system.

[0043] Such as Figure 4As shown in the figure: The RS485 (MAX14783) chip and CAN (TJA1042) chip of the torque control module interact with the RS485_A (MAX14783) and CAN_A (TJA1042) of the control box and display interface system through twisted pair (with a wire length within 20 mm), maintaining a high communication rate of 2M to transmit data in real time. If the plug of port A or port B becomes loose or is directly pulled out, corresponding fault codes will appear in the control box and display interface system, and be accompanied by voice transmission to the human ear. If port A or port B returns to the tightly connected state again, the RS485&&CAN of the torque control module and the RS485_A&&CAN_A of the control box and display interface system will continue to request and respond, and the two parties will conduct correct real-time data interaction to ensure the normal operation of the entire intelligent control tightening system.

[0044] The communication data of RS485 and CAN are different. RS485 mainly conducts Figure 1 real-time transmission of sensor data in the system to ensure the accuracy and reliability of the position signal, making the output torque during tightening accurate and stable; The CAN bus is for data transmission of auxiliary functions, mainly covering brightness adjustment of LED lights, real-time response of the tilt angle of the torque control module, forward and reverse switch signals, and real-time data transmission of the start switch signal of the transmission part.

[0045] The torque control module covers different torque ranges and appearance dimensions. The torque of each intelligent industrial control tightening system is different, mainly reflected in the different torques output by the transmission part (motor and reducer) and the appearance size. For a small-torque tightening control system, the transmission part will be relatively thin, and the appearance will also be relatively thin; for a large-torque range, the transmission part will be relatively thick, and the appearance will naturally become larger and thicker. This new type of intelligent industrial control communication tightening system can automatically identify the size of the torque output based on RS485 and CAN communications. It mainly automatically identifies the torque size by the magnitude of the current consumed by the motor and reducer in the transmission part.

[0046] The innovation of the present invention lies in the dual communication channel architecture: RS485 communication channel: used to transmit high-precision position sensor data and torque control parameters to ensure the accuracy and stability of the tightening process. CAN bus communication channel: used to transmit device status parameters (such as LED brightness, tilt angle, forward and reverse signals, etc.) to realize real-time control of auxiliary functions. The communication rate of the dual channels can reach 2 Mbps, supporting high-speed data interaction.

[0047] Adaptive recognition technology: The current detection unit monitors the current parameters of the transmission part (motor and reducer) in real time. Based on the current-torque conversion algorithm, it dynamically identifies the current torque output range. Automatically matches the control parameters of the control box system to achieve arbitrary adaptation of different torque range modules.

[0048] Fault detection and recovery mechanism: When an abnormal connection of the communication port (Port A or Port B) is detected, the system generates a specific fault code and triggers a voice alarm. After the port connection is restored, the system automatically executes the handshake protocol verification and data integrity check to ensure the reliable reconstruction of the communication link.

[0049] Modular design: The torque control module adopts a standardized interface design, supporting the mechanical connection between modules with different appearance sizes and torque ranges and the control box system. The universal power interface (20 - 48V wide voltage input) and the modular heat dissipation structure are adapted to diverse application scenarios.

[0050] In other words, the solution of the present invention is to provide a new type of intelligent industrial control communication tightening system. The torque control module, the control box and the interface display system interact with each other through two different communication methods, mainly RS485 and CAN bus communication. The mutual interaction rate can reach more than 2M. Moreover, the torque control module is not limited by the torque size, and can be interchanged with any one of the control box and the interface display system in terms of appearance size, and the stability and reliability of the entire communication system are ensured. The key point is that the two different (RS485 and CAN) communication methods each have functional effects to achieve automatic identification of the torque size, and different torque size ranges and appearance sizes can be arbitrarily adapted to a control box and a display interface system. Through the two different (RS485 and CAN) communication interaction methods, the communication performance and reliability of the system are improved. At the same time, the intelligence of the tightening control system is realized, the influence of electromagnetic interference is reduced, and the production efficiency is improved.

[0051] To achieve the above object, the present invention also provides an intelligent tightening control processing system based on a dual communication channel, as Figure 5 shown. The system specifically includes: A communication link creation unit, configured to create at least one bidirectional communication link based on RS485 and CAN buses; wherein, the bidirectional communication link is located between the torque control module and the control box system; A first data generation unit, configured to generate and obtain first data corresponding to the intelligent tightening control to be processed, and process and transmit the first data in real time based on the bus; wherein, the first data includes position sensor data and device status parameter data; A second data generation unit, configured to generate and obtain second data corresponding to the intelligent tightening control to be processed, and generate corresponding third data in real time according to the second data; wherein, the second data is the current parameter data for monitoring the transmission part; the third data is the current torque output range data; A data adaptation processing unit, configured to arbitrarily adapt and process tightening modules and control box systems with different torque ranges based on the third data, in combination with the first data and the second data.

[0052] The communication link creation unit further includes: A first generation module, configured to generate and obtain first signal data corresponding to 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; the fourth data is handshake request data; A first processing module, configured to perform a handshake protocol for verification processing at least three times based on the fourth data; after successful verification, a two-way data interaction channel is established and the communication rate is not lower than 2 Mbps; otherwise, re-verification processing is performed. A first monitoring module, configured to monitor the states of RS485 and CAN bus communication ports in real time based on the two-way communication link; wherein, it includes fault detection and recovery processing. A second processing module, configured to generate corresponding fault codes and trigger voice alarms when abnormal connections of port A or port B are detected; after the port connection is restored, automatically perform handshake protocol verification and data integrity verification, and restore the corresponding communication link. And / or, the second data generation unit further includes: A third processing module, configured to dynamically adjust and process the corresponding third data during the tightening process according to the first data collected in real time. A fourth processing module, configured to adjust and process LED brightness, tilt angle, and forward and reverse control signal data in real time based on the first data. A second generation module, configured to calculate and generate corresponding fifth data based on the second data in combination with a preset current-torque conversion algorithm; wherein, the fifth data is current torque output value data. A fifth processing module, configured to automatically adjust and process the control parameter data in the control box system according to the fifth data.

[0053] The second processing module further includes: A verification processing module, configured to perform CRC verification processing on the transmitted data packets, and retransmit the data packets until the verification is successful when the verification fails; after the verification is successful, resume real-time data interaction.

[0054] That is to say, in the system embodiment of the present invention, an intelligent tightening control system based on a dual communication channel is provided. The system includes: a torque control module for integrating RS485 and CAN bus communication modules; a control box system for data processing and instruction issuing; an interface display system for real-time display of system status and parameters. The system supports arbitrary adaptation of tightening modules with different torque ranges to the control box system. Among them, the control box system is configured with a fault detection and recovery mechanism, including fault code generation, voice alarm, and automatic reconnection functions.
