Bar apron board redundancy controller

Abstract

The invention discloses a bar apron board redundancy controller. The controller comprises an apron board electric control box and a plurality of apron board electromagnetic valves for controlling an apron board to act, and further comprises a control loop and an execution loop; the control loop is used for supplying power to the apron board electric control box in a scattered arrangement and local control mode; and the execution loop is used for realizing automatic switching of redundant power supplies of the plurality of apron board electromagnetic valves. According to the controller, the output power can be automatically adjusted according to the actual working condition of field equipment by means of an electric control box and an auxiliary system which are arranged on site; and when an abnormal condition occurs, the controller can effectively avoid shutdown and abnormal action of the apron board, unnecessary loss and unnecessary working procedures are reduced, the controller is reliable in application, and the service life of equipment can be prolonged.

Description

technical field [0001] The present invention relates to the technical field of bar wire production equipment, and more specifically relates to a bar skirt redundancy controller. Background technique [0002] At present, the electric control system of the cooling bed area used in the bar line is based on the control method of PLC and the on-site signal station. The on-site intermediate relay controls the specific control of the solenoid valve. Once the intermediate relay has a problem or the electrical components in the control box are damaged, or the control The voltage drop of the signal due to the long line will affect the control accuracy, which will lead to the collapse of the apron control system, and then affect the control of the electrical equipment in the entire cooling bed area, which will hinder the production capacity and increase the labor intensity of personnel. Contents of the invention [0003] The object of the present invention is to provide a redundant c...
