This invention discloses a protocol conversion method based on a dual buffer. Addressing the issue of high-priority packet loss when using a circular buffer in a serial port, it proposes a method combining a weighted cyclic priority queue and a circular buffer. This method includes: configuring a weighted cyclic priority queue in the serial port; configuring a circular buffer in the serial port; and sending or receiving packets through the dual buffer. A welding robot and a gateway are connected via a network cable, while the gateway and the welding machine are connected via a serial cable. The welding robot and gateway use a Process Field Network (PROFINET), and the gateway and welding machine use the MODBUS protocol. The gateway performs protocol conversion, thereby enabling the welding robot to control the welding machine. This invention employs a method combining a weighted cyclic priority queue and a circular buffer, reducing the loss of high-priority packets and improving the stability of the gateway system.

Electronic system for connecting torque wrench charging cradles, comprising a plurality of charging cradles (B1-Bn), each suitable for housing in a special housing (G) an electronic or mechatronic type torque wrench (D), connected to each other in series by a serial cable (C) capable of transferring electrical energy and data between one cradle and the other. The system further comprises a charging station (3), connected via a power cable (CA) to the first (B1) or the last (Bn) charging cradle in the series.
