Application of network in slip ring communication

Abstract

The invention relates to the application of a network in slip ring communication, which is characterized in that: by the communication control of a PROFIBUS-DP bus, an ET200 station is placed on a rotating part of a ladle turret and an IM153-1 communication template of the PROFIBUS-DP is arranged in the configuration of the ET200 station; and an IM467 communication template of the PROFIBUS-DP is arranged in the configuration of an S7-400 in a PLC room cabinet; the IM467 communication template is connected with the IM153-1 communication template positioned at the ET200 station on the rotating part of the ladle turret through contacts of the slip ring by using the PROFIBUS-DP bus so as to control the lifting of an arm and a cover of the ladle turret and the on and off of a slide gate and todisplay all states and measurement values of a weighing system. The application of the network in communication through the slip ring has the advantages of simplifying a circuit in the slip ring, economically saving cable cost and construction cost, and simplifying equipment control as well as further maintenance. The slip ring adopts the PROFIBUS-DP network communication control, so the equipment failure rate is lowered, operation time of a casting machine is increased and the repair and maintenance are extremely convenient.

Description

1. Technical field [0001] The invention relates to the application of a network in slip ring communication, in particular to the application of the network in the communication between electrical equipment of a bale turntable through a slip ring, which belongs to the field of network communication. 2. Background technology [0002] The ladle turret is the key part of the continuous casting machine, its stable operation is directly related to the output and quality of the continuous casting machine. The ET200 (Siemens decentralized control) station for continuous casting blooms is researched and developed by Baotou Steel Plant through slip ring communication. At present, electrical equipment such as the limit of the bale turntable, hydraulic valves, and weighing system equipment are connected through hard-wired point-to-point connections through slip rings, and enter the S7-400 (Siemens centralized control) of the control room of the PLC (programmable logic controller).
