Abstract

The invention discloses a fan networking system based on the RS‑485 enhanced Modbus communication protocol. The fan networking system includes: a controller, a gateway communicating with the controller, and multiple A transponder and the fan group connected with the plurality of transponders; the frame format in the Modbus communication protocol includes: frame header, instruction code, fan address, fan group address and error checking part; the present invention changes The frame format of the traditional MODBUS communication protocol makes the grouping of the fan system simple and the networking simple and efficient, and realizes the dual-address management of the fan unit address and the fan unit address, thereby facilitating the large-scale grouping and management of the fans.

Description

technical field [0001] The invention relates to the technical field of ventilation equipment control, in particular to a fan networking system based on the RS-485 enhanced Modbus communication protocol. Background technique [0002] New smart wind turbines have higher and higher requirements for group control networking and remote control of wind turbines. At present, the traditional standard Modbus communication protocol is mostly used in the market to meet the networking requirements of wind turbines. This protocol has a wide range of applications and a relatively simple frame format. Compact, standardized format, easy to transmit, easy to understand, easy for users to use and easy to develop. As an industrial standard protocol, users do not need to understand the technical details of Modbus, but only need to refer to the instruction manual and the provided application examples, and complete the configuration as required. No complicated programming is required, and the con...
