Abstract:

Blowing-carding system equipment is diverse, and some conventional equipment has low degree of automation, and relatively-lagged communication networking function.  The carding doffer process has defects of backward transmission control technology and high failure rate. In view of the above, by using Siemens PLC as center controller and using PROFIBUS-DP industrial field bus as unit networked monitoring system, the function of parameters modification, task assigning, dynamic display, data storage, fault analysis and so on are realized. At the same time, the techniques of carding doffer transmission are improved by vector inverter. The results show that the system can achieve the blowing-carding online monitoring and management, enhancing the level of production and management of enterprise automation, saving energy and reducing consumption.

Key words: blowing-carding, PROFIBUS-DP, networked monitoring, vector inverter
