Problems solved by technology
Most of the existing 485 communication methods are to connect the 485 communication module (host computer) directly with the frequency converter for communication. There will be a lot of wiring to the device, making the wiring very complicated, which will easily cause communication instability and interference

Embodiment Construction
[0010] Referring to the drawings, the present invention includes a host computer 1, a 485 communication distributor 3 and a number of frequency converters 5. The host computer 1 and the 485 communication distributor 3 are connected through a shielded twisted pair 2, and the 485 communication distributor 3. Connect with the frequency converter 5 through the network cable 4 with a crystal head. The data sent by the upper computer 1 is transferred through the 485 communication distributor 3 and then sent to the designated frequency converter 5 to realize the data exchange between the frequency converter 5 and the upper computer 1 . The frequency converter 5 is connected to each motor in other functional modules.

The invention relates to a novel distributor opening control device which comprises an upper computer, a 485 communication distributor and a frequency converter. The upper computer is connected with the 485 communication distributor through a shielded twisted pair, and the 485 distributor is connected with the frequency converter through a network cable. The upper computer is in communication with the frequency converter through the 485 communication distributor, the 485 communication distributor serves as a transit element for communication, when multiple frequency converters are used for communication, the problems that wiring is complex and communication is prone to interference are solved, a control system is maintained more easily, the frequency converter is in communication with the 485 communication distributor through the crystal-head network cable, the faults caused by wiring are greatly reduced, and the whole system is made more stable.
Description
technical field [0001] The invention relates to a textile machine, in particular to a novel distributor opening and cleaning control device. Background technique [0002] In the field of automation, EIA RS-485 has become the dominant communication standard for data transmission in industrial applications due to its long-distance, multi-node, and low-cost transmission line characteristics. Most of the existing 485 communication methods are to connect the 485 communication module (host computer) directly with the frequency converter for communication. There will be a lot of wiring to the device, making the wiring very complicated, which will easily cause communication instability and interference. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art and proposes a novel dispenser opening and clearing control device. The system uses a 485 communication dispenser, which reduces wiring, makes the control system more stable, and ...
